Assessment of Left Ventricular Diastolic Dysfunction in Cases with Liver Cirrhosis

Background: Cirrhosis is a long-term inflammatory process of hepatic tissue condition that mainly affects people aged 50 to 60. This study aims to assess Left ventricular diastolic dysfunction (LVDD) in cases with cirrhotic liver by conventional, tissue Doppler and two-dimensional speckle tracking echocardiography to clarify the correlation between the severity of cirrhotic liver and LVDD. Methods: A prospective case-control research involved 100 adult cases with confirmed HCV and HBV. Cases were divided into 4 equal group: Group A: Child A cases, group B: Child B cases, group C: Child C cases and group D (Controls): healthy non-hepatic subjects of the same age and sex who have normal blood pressure, nonsmoking participants with no further concomitant problems. Results: Number of cases with LVDD had a statistical noticeable increase in Child A, B, and C (p =0.004, <0.001, and <0.001 respectively. LAVi had a statistical noticeable increase in Child C / B (p =0.013 and p =0.014). Conclusion: Left atrial volume index (LAVi) had a statistical noticeable increase in Child C / B in comparison to the controls but E m, E l were statistical noticeable lower in Child C / B. /E had a statistical noticeable increase in Child C group, LVSRe had a statistical noticeable decrease in Child C group but it was insignificantly different across Child A / B/ C and controls and across Child B / C and controls.

Correlation of glycated hemoglobin and diastolic dysfunction in type 2 diabetes mellitus patients in a tertiary care centre

Background: There is a substantial increase in the coincidence of diabetes mellitus and cardiomyopathy. The cardiomyopathy may occur in patients who have no evidence of large vessel disease or abnormalities. The early and commonest hemodynamic derangement of diabetic cardiomyopathy is left ventricular diastolic dysfunction. So, the present study was undertaken to assess the prevalence of diastolic dysfunction in patients with type 2 diabetes and to assess the correlation of diastolic dysfunction and HbA1c% levels. Materials and methods: A total of 100 diabetic patients with minimum 5 years duration of diabetes were selected from Malla Reddy Hospital, Suraram from August 2020 to June 2022. Patients with minimum history of 5 years of type 2 diabetes were scrutinized for Doppler echo cardiography and HbA1c levels. Results: Diastolic dysfunction of left ventricle was observed in 58 patients out of 100, of which 54 (93.1%) patients had HbA1c% of > 6.4. 2 (3.4%) patients belong to HbA1c% group of 5.7-6.4. and 2(3.4%) patients belong to HbA1c% of < 5. Conclusion: Our findings indicate that myocardial damage in patients with diabetes affects diastolic function before systolic function. Diabetic cardiomyopathy is characterized by an early diastolic dysfunction and a later systolic dysfunction. Impaired diastolic function was not affected by sex or type of diabetes. Even young patients with diabetics with normal systolic ventricular function have diastolic dysfunction, which serves as a marker of a diabetic cardiomyopathy. Diastolic seems not to correlate with disease duration. HbA1c% can be a very good indicator of long term prognosis. Strong corelation exists between diastolic dysfunction and HbA1c.

Correlation between Serum Osteoprotegerin/Soluble Receptor Activator of Nuclear Factor-κβ Ligand Levels and the Left Ventricular Diastolic Dysfunction in Type 2 Diabetes / 中山大学学报(医学科学版)

ObjectiveTo study the possible correlation between serum osteoprotegerin （OPG）/soluble receptor activator of the nuclear factor κB ligand （sRANKL） levels and the left ventricular diastolic dysfunction （LADD） in patients with type 2 diabetes mellitus （T2DM）. MethodsTotally 68 T2DM patients and 37 healthy controls were selected. Serum OPG and sRANKL were determined by solid-phase enzyme-linked immunosorbent assay （ELISA）. The left ventricular diastolic function of T2DM patients was measured by transthoracic echocardiography， where E/A < 1 were regarded as LVDD. T2DM patients were further divided into two subgroups according to E/A ratio （E/A≥1.0 and E/A<1）. Spearman correlation analysis， logistic regression and ROC curves were used to assess the possible correlation between serum OPG/sRANKL and LADD in T2DM patients. ResultsCompared with the healthy controls， serum OPG level in T2DM patients was higher with statistically significant difference （P <0.01）， while serum sRANKL level was lower without statistically significant difference （P =0.32）. T2DM patients with E/A<1 had significantly higher OPG level and lower sRANKL level than those with E/A≥1（P <0.01） in subgroup analysis. Spearman correlation analysis showed serum OPG level was negatively correlated with E/A ratio， while sRANKL was positively related with E/A ratio. In single factor logistic regression analyses， serum OPG ［OR （95% CI）=1.068 （1.031， 1.106）， P<0.001］ and sRANKL ［OR （95% CI）=0.976 （0.959， 0.992）， P=0.003］ were significant correlation with LVDD in T2DM patients. ROC curve analysis showed that the sensitivity and specificity of combined OPG and sRANKL in diagnosing T2DM patients LADD were 78.13% and 88.3%， respectively （area under the curve： 0.857； 95% CI=（0.768， 0.946）； P<0.001）. ConclusionsThe elevated OPG and decreased sRANKL levels may be associated with LADD in T2DM patients.

Parâmetros Ecocardiográficos Simples são Fortes Preditores de Risco Cardiovascular em Indivíduos Assintomáticos: Coorte Elsa-Brasil / Simple Echocardiographic Parameters are Strong Predictors of the Cardiovascular Risk in Asymptomatic Individuals: Elsa-Brasil Cohort

Resumo Fundamento vários estudos avaliam alterações ecocardiográficas como preditores de risco cardiovascular; entretanto, nenhum associa risco cardiovascular global com alterações ecocardiográficas em brasileiros. Objetivo Este estudo avalia a associação entre risco cardiovascular global (ASCVD) e achados ecocardiográficos como hipertrofia ventricular esquerda (HVE), disfunção diastólica (DDVE) e aumento do volume do átrio esquerdo (AE). Métodos A população foi composta por participantes do ELSA-Brasil que realizaram ecocardiografia entre 2008 e 2010 (n = 2.973). Eram assintomáticos e não tinham história de doença cardiovascular (DCV). O escore ASCVD foi calculado em dois períodos: 2008-2010 e 2012-2014. Razões de prevalência (RP) foram estimadas com intervalos de confiança (IC) de 95%. Resultados Evidenciou-se associação entre alterações ecocardiográficas e alto risco cardiovascular global (escore ASCVD ≥ 7,5) nos dois períodos do estudo, separadamente. O risco global combinado (baixo risco no primeiro período e alto risco no segundo período) teve associação significativa apenas com DDVE (RP = 3,68; IC 95%: 2,63-5,15) e HVE (RP = 2,20; IC 95%: 1,62-3,00). Conclusão Alterações ecocardiográficas (DDVE, HVE e aumento do volume do AE) são preditores independentes de risco cardiovascular em adultos brasileiros sem DCV prévias.

Abstract Background Several studies have evaluated echocardiographic abnormalities as predictors of cardiovascular risk; however, none have associated the global cardiovascular risk with echocardiographic abnormalities in the Brazilian population. Objective This study evaluates the association between the global cardiovascular risk (ASCVD score) and three echocardiographic abnormalities: left ventricular hypertrophy (LVH), left ventricular diastolic dysfunction (LVDD), and increased left atrium (LA) volume. Methods The study population was composed of participants from ELSA-Brasil who underwent echocardiography between 2008 and 2010 (n = 2973). They were asymptomatic and had no history of cardiovascular disease. The ASCVD score was calculated in two periods: 2008-2010 and 2012-2014. Prevalence ratios (PR) were estimated with 95% confidence intervals (CI). Results There is an association between echocardiographic abnormalities and high global cardiovascular risk (ASCVD score ≥ 7.5) in both study periods, separately. The combined global risk (low risk in the first period and high risk in the second period) was significantly associated only with LVDD (PR = 3.68, CI 95% 2.63-5.15) and LVH (PR = 2.20, 95% CI 1.62-3.00). Conclusion Echocardiographic abnormalities (LVDD, LVH, and increased LA volume) are independent predictors of cardiovascular risk in Brazilian adults.

A study of left ventricular diastolic dysfunction in patients of sickle cell disease

Background:Left ventricular diastolic filling patterns are altered in patients with sickle cell anaemia andthese diastolic abnormalities may be present in the absence of heart failure. These abnormal patterns suggest an intrinsic myocardial abnormality in patients with sickle cell anaemia andmay prove to be early markers of cardiac disease. The ventricles do not properly relax and become stiff meaning they cannot fill with blood properly.Methods:This study was carried out in tertiary health care hospital in western India, where homozygous sickle cell disease patients and age and haemoglobin matched controls were taken into cross sectional observational study design.Results:The mean values of E, A, E/A, IVRT, DT, AT, were in normal range in controls. In cases although the mean values of E, A, E/A, IVRT, DT, AT were in normal range, there were 19 cases of sickle cell anaemia who had significant alteration in indices of diastolic LV function from normal range. Out of these 20 cases with diastolic dysfunction, 11 cases had significant increase in (E) velocity from normal range with E/A ratio more than 2 suggestive of restrictive filling pattern of diastolic dysfunction while in 8 cases E value was less than normal with increase in (A) velocity and E/A ratio was less than 1 suggestive of impaired relaxation pattern of diastolic dysfunction. When indices of diastolic LV function were compared in cases and controls, mean early peak filling velocity (E) was significantly higher in cases. Conclusions:In present study, out of 37 cases 19 (51%) cases had LV diastolic dysfunction.Of these 19 cases with diastolic dysfunction, 11 cases had restrictive filling pattern and 8 cases had impaired relaxation pattern of diastolic dysfunction.

Advances in extracardiac mechanisms for heart failure with preserved ejection fraction / 中南大学学报(医学版)

Heart failure with preserved ejection fraction (HFpEF) is a syndrome with highly heterogeneous clinical symptoms, and its incidence has been increasing in recent years. Compared with heart failure with reduced ejection fraction (HFrEF), HFpEF has a worse prognosis. Traditional therapies targeting the internal mechanisms of the heart show limited or inefficacy on HFpEF, and new therapeutic targets for HFpEF are expected to be found by focusing on the extracardiac mechanisms. Recent studies have shown that cardiopulmonary pathophysiological interaction exacerbates the progression of HFpEF. Hypertension, systemic vascular injury, and inflammatory response lead to coronary microvascular dysfunction, myocardial hypertrophy, and coronary microvascular remodeling. Acute kidney injury affects myocardial energy production, induces oxidative stress and catabolism of myocardial protein, which leads to myocardial dysfunction. Liver fibrosis mediates heart injury by abnormal protein deposition and inflammatory factors production. Skeletal muscle interacts with the sympathetic nervous system by metabolic signals. It also produces muscle factors, jointly affecting cardiac function. Metabolic syndrome, gut microbiota dysbiosis, immune system diseases, and iron deficiency promote the occurrence and development of HFpEF through metabolic changes, oxidative stress, and inflammatory responses. Therefore, the research on the extracardiac mechanisms of HFpEF has certain implications for model construction, mechanism research, and treatment strategy formulation.

Effect of positive end-expiratory pressure on cardiac function in patients with early left ventricular diastolic dysfunction: a prospective cohort study / 中华危重病急救医学

Objective:To evaluate the effect of positive end-expiratory pressure (PEEP) ventilation on cardiac function in patients with early left ventricular (LV) diastolic dysfunction undergoing laparoscopic radical gastrectomy.Methods:Patients who underwent laparoscopic radical gastrectomy under elective general anesthesia from July 2021 to February 2022 at the Subei People's Hospital were enrolled [age 60-75 years old, American Society of Anesthesiologists (ASA) grade Ⅰ-Ⅱ, and left ventricular ejection fraction (LVEF) > 0.50]. Transthoracic echocardiography (TTE) was performed before operation, and the peak early diastolic velocity (E peak) and peak late diastolic velocity (A peak) at the mitral ostium were recorded and the E/A and E peak deceleration time (DT) were calculated. Then isovolumic relaxation time (IVRT) and early peak mitral annular diastolic velocity (e') were recorded and left ventricular E/e' (LVE/e') was calculated. According to the E/A, mitral e', LVE/e', DT, and IVRT, the patients were divided into early LV diastolic dysfunction group (E/A < 1, mitral e' < 7 cm/s, LVE/e' > 14, DT > 200 ms, and IVRT > 100 ms) and normal cardiac function group (1 < E/A < 2, 160 ms < DT < 240 ms, and 70 ms < IVRT < 90 ms), with 35 patients in each group. Both groups were received fixed 5 cmH 2O (1 cmH 2O≈0.098 kPa) PEEP 5 minutes after the beginning of the pneumoperitoneum until the end of the procedure. A volume controlled ventilation was used with a tidal volume (VT) of 7 ml/kg, an inspired oxygen concentration of 0.60, and an inspiratory to expiratory ratio of 1∶2. Left and right myocardial systolic and diastolic function related parameters, including LVEF, LV global longitudinal strain (LVGLS), tricuspid annulus plane systolic migration (TAPSE), the peak early diastolic velocity (E peak) at the mitral and tricuspid valve ostia and the peak early diastolic velocity (e') at the corresponding annulus were measured by transesophageal echocardiography (TEE) before tracheal intubation (T 0), 5 minutes after the pneumoperitoneum (T 1), 5 minutes after PEEP ventilation (T 2), 30 minutes after PEEP ventilation (T 3), and 5 minutes after the end of pneumoperitoneum (T 4), respectively. The left and right ventricular myocardial performance index (LVMPI/RVMPI) was calculated. Results:Finally, 60 patients were included in the analysis, including 28 patients in the early LV diastolic dysfunction group and 32 patients in the normal cardiac function group. Compared with those at T 0, mean arterial pressure (MAP), LVEF, mitral e', LVGLS, tricuspid e' and TAPSE were significantly lower in the normal cardiac function group at T 1, and the early LV diastolic dysfunction group at T 1, T 2, and T 3, and LVMPI, LVE/e', RVE/e', and RVMPI were significantly higher. At T 4, the LVE/e' and the RVE/e' were significantly higher in the early LV diastolic dysfunction group than those at T 0 (LVE/e': 16.52±1.26 vs. 14.32±1.09, and RVE/e': 18.71±1.74 vs. 16.51±1.93, respectively, both P < 0.05), Mitral e' and tricuspid e' were significantly lower than those at T 0 [mitral e' (m/s): 0.07±0.01 vs. 0.09±0.01, tricuspid e' (m/s): 0.06±0.01 vs. 0.08±0.01, both P < 0.05]. Compared with the normal cardiac function group, MAP, LVEF, mitral e', LVGLS, tricuspid e', and TAPSE at T 1, T 2, and T 3 were significantly lower in the early LV diastolic dysfunction group, while LVMPI, LVE/e', RVE/e', and RVMPI were significantly higher. At T 4, the LVE/e' and the RVE/e' were significantly higher in the early LV diastolic dysfunction group than those in the normal cardiac function group (LVE/e': 16.52±1.26 vs. 9.87±1.25, RVE/e': 18.71±1.74 vs. 10.97±1.70, both P < 0.05). Mitral e' and tricuspid e' were significantly lower in the normal cardiac function group [mitral e' (m/s): 0.07±0.01 vs. 0.11±0.02, tricuspid e' (m/s): 0.06±0.01 vs. 0.10±0.02, both P < 0.05]. Conclusions:In early LV diastolic dysfunction patients, compared with patients with normal cardiac function, 5 cmH 2O PEEP can further exacerbate left and right myocardial systolic and diastolic function in patients during pneumoperitoneum; when the pneumoperitoneum was ended, 5 cmH 2O PEEP only worsen left and right myocardial diastolic function in patients, and did not affect left and right myocardial systolic function.

ABSTRACT: Purpose: Despite the recognized benefits of practicing physical activity in patients with cardiovascular disease, it is believed that patients with heart failure and reduced ejection fraction with non-sedentary behavior may present an improvement in cardiovascular function and quality of life compared to sedentary patients, even if they do not practice regular physical ex-ercise. The aim of the present study was to compare functional capacity, systolic and diastolic cardiac function and quality of life of sedentary and non-sedentary patients with heart failure and reduced ejection fraction. Methods: Patients with heart failure and ejection fraction below 50% were divided into two groups, Sedentary (n = 45) and Non-Sedentary (n = 36), using the IPAQ questionnaire. These two groups were evaluated with clinical evaluation, quality of life SF-36 questionnaire, Cooper walking test and transthoracic echocardiography. They were compared by Chi-Square test for categorical variables or Test T or Man-Whitney for continuous variables; the level of significance adopted in the statistical analysis was 5%. Results: The groups were homogeneous in relation to the baseline characteristics and etiology. The Non-Sedentary Group had fewer patients with severe symptoms (p <0.01), less necessity of digitalis (p = 0.02) and better left ventricle fractional shorten-ing (p = 0.03). There was no apparent difference in the walk-test data between groups. Additionally, there was a greater impairment in the functional capacity of the SF-36 Questionnaire in the Sedentary Group. Conclusion: Considering the sample limitation, patients with heart failure and non-sedentary behavior have greater tolerability to exercise because they have fewer limiting symptoms and better quality of life in the functional capacity domain than sedentary patients.

Calcium homeostasis behavior and cardiac function on left ventricular remodeling by pressure overload

Sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) and sarcolemmal Na+/Ca2+ exchanger (NCX1) structures are involved in heart cell Ca2+ homeostasis. Previous studies have shown discrepancies in their function and expression in heart failure. The goal of this study was to evaluate heart function and hypertrophied muscle Ca2+-handling protein behavior under pressure overload. Twenty male Wistar rats were divided into two groups: Aortic stenosis (AoS), induced by a clip placed at the beginning of the aorta, and Control (Sham). After 18 weeks, heart function and structure were evaluated by echocardiogram. Myocardial function was analyzed by isolated papillary muscle (IPM) at basal condition and Ca2+ protein functions were evaluated after post-pause contraction and blockage with cyclopiazonic acid in IPM. Ca2+-handling protein expression was studied by western blot (WB). Echocardiogram showed that AoS caused concentric hypertrophy with enhanced ejection fraction and diastolic dysfunction inferred by dilated left atrium and increased relative wall thickness. IPM study showed developed tension was the same in both groups. AoS showed increased stiffness revealed by enhanced resting tension, and changes in Ca2+ homeostasis shown by calcium elevation and SERCA2a blockage maneuvers. WB revealed decreased NCX1, SERCA2a, and phosphorylated phospholambam (PLB) on serine-16 in AoS. AoS had left ventricular hypertrophy and diastolic dysfunction compared to Sham; this could be related to our findings regarding calcium homeostasis behavior: deficit in NCX1, SERCA2a, and phosphorylated PLB on serine-16.

Diastolic versus systolic dysfunction in patients with chronic liver disease ­ a single center study in South-South, Nigeria

Objectives: The term cirrhotic cardiomyopathy (CCM) has been used to describe the constellation of cardiovascular abnormalities including diastolic and systolic dysfunctions in patients with chronic liver disease (CLD). CCM contributes to morbidity and mortality associated with CLD. The aim of the study was to evaluate the left atrial and ventricular geometry, systolic and diastolic functions in patients with CLD. Material and Methods: This was a cross-sectional analytical study that involved 80 patients with CLD seen at University of Calabar Teaching Hospital, Calabar, Nigeria, and 80 apparently healthy controls matched for age/ gender. The participants were interviewed, examined and had resting transthoracic echocardiography. The data were analyzed using IBM SPSS version 20.0. Results: A total of 160 subjects were recruited into the study with a male to female ratio of 2.8:1. There was no difference in the mean age of cases and controls (P = 0.115). Systolic function of the left ventricle was similar in the two arms. However, left ventricular diastolic dysfunction, left atrial enlargement, and increased left ventricular mass index (LVMI) were more prevalent among the patients with CLD compared to controls (P < 0.05). Conclusion: The study demonstrated increased left atrial diameter, increased LVMI associated with diastolic dysfunction, and preserved systolic function at rest among CLD patients. Keywords: Chronic liver disease, Diastolic dysfunction, Systolic dysfunction

Estudo Comparativo da Doença Coronariana Microvascular Causada por Doença de Chagas e por Outras Etiologias / Chagas Cardiomyopathy as the Etiology of Suspected Coronary Microvascular Disease. A Comparison Study with Suspected Coronary Microvascular Disease of Other Etiologies

Resumo Fundamento A doença de Chagas (DC) constitui uma causa potencial negligenciada de doença microvascular coronariana (DMC). Objetivos Comparar pacientes com DMC relacionada à DC (DMC-DC) com pacientes com DMC ligada a outras etiologias (DMC-OE). Métodos De 1292 pacientes estáveis, encaminhados para angiografia coronária invasiva para elucidar o padrão hemodinâmico e a causa de angina, 247 apresentaram coronárias subepicárdicas normais, e 101 foram incluídos após aplicação dos critérios de exclusão. Desses, 15 compuseram o grupo de DMC-DC e suas características clínicas, hemodinâmicas, angiográficas, e cintilográficas foram comparadas às do grupo de 86 pacientes com DMC-OE. O nível de significância estatística para todas as comparações adotado foi de 0,05. Resultados Pacientes com suspeita de DMC-DC apresentaram características antropométricas, clínicas e angiográficas, além de alterações hemodinâmicas e de perfusão miocárdica estatisticamente comparáveis às detectadas nos 86 pacientes com DMC-OE. Disfunção ventricular diastólica, expressa por elevada pressão telediastólica do ventrículo esquerdo, foi igualmente encontrada nos dois grupos. Entretanto, em comparação a esse grupo com DMC-OE, o grupo com DMC-DC exibiu fração de ejeção ventricular esquerda mais baixa (61,1 ± 11,9 vs 54,8 ± 15,9; p= 0,049) e mais elevado escore de mobilidade da parede ventricular (1,77 ± 0,35 vs 1,18 ± 0,26; p= 0,02). Conclusão A cardiomiopatia crônica da doença de Chagas esteve associada à etiologia de possível doença microvascular coronariana em 15% de amostra de 101 pacientes estáveis, cujo sintoma principal era angina requerendo elucidação por angiografia invasiva. Embora os grupos DMC-DC e DMC-OE apresentassem características clínicas, hemodinâmicas, e de perfusão miocárdica em comum, a disfunção global e segmentar do ventrículo esquerdo foi mais grave nos pacientes com DMC associada à DC em comparação à DMC por outras etiologias.

Abstract Background Chagas disease (CD) as neglected secondary form of suspected coronary microvascular dysfunction (CMD). Objectives Comparison of patients with CMD related to CD (CMD-CE) versus patients with CMD caused by other etiologies (CMD-OE). Methods Of 1292 stable patients referred for invasive coronary angiography to elucidate the hemodynamic pattern and the cause of angina as a cardinal symptom in their medical history, 247 presented normal epicardial coronary arteries and 101 were included after strict exclusion criteria. Of those, 15 had suspected CMD-CE, and their clinical, hemodynamic, angiographic and scintigraphic characteristics were compared to those of the other 86 patients with suspected CDM-OE. Level of significance for all comparisons was p < 0.05. Results Patients with suspected CMD-CE showed most anthropometric, clinical, angiographic hemodynamic and myocardial perfusion abnormalities that were statistically similar to those detected in the remaining 86 patients with suspected CMD-OE. LV diastolic dysfunction, expressed by elevated LV end-diastolic pressure was equally found in both groups. However, as compared to the group of CMD-OE the group with CMD-CE exhibited lower left ventricular ejection fraction (54.8 ± 15.9 vs 61.1 ± 11.9, p= 0.049) and a more severely impaired index of regional wall motion abnormalities (1.77 ± 0.35 vs 1.18 ± 0.26, p= 0.02) respectively for the CMD-OE and CMD-CE groups. Conclusion Chronic Chagas cardiomyopathy was a secondary cause of suspected coronary microvascular disease in 15% of 101 stable patients whose cardinal symptom was anginal pain warranting coronary angiography. Although sharing several clinical, hemodynamic, and myocardial perfusion characteristics with patients whose suspected CMD was due to other etiologies, impairment of LV segmental and global systolic function was significantly more severe in the patients with suspected CMD related to Chagas cardiomyopathy.

Falla cardiaca con fracción de eyección preservada: generalidades y aproximación en el perioperatorio / Heart failure with preserved ejection fraction: overview and perioperative management / Falência cardíaca com fração de ejeção preservada: generalidades e abordagens no perioperatório

Resumen: La falla cardiaca con fracción de eyección preservada es frecuente y de difícil abordaje perioperatorio en población adulta. Es un síndrome clínico complejo con alteraciones estructurales y funcionales cardiacas con fracción de eyección del ventrículo izquierdo preservada (FEVI) ≥ 50 %. Los biomarcadores, la ecocardiografía, el cateterismo cardiaco y otros métodos no invasivos confirman el diagnóstico. Actualmente no existe manejo específico efectivo comparado al de la falla con FEVI reducida. Objetivo: Elaborar una revisión de la literatura sobre la falla cardiaca con fracción de eyección preservada y sus implicaciones anestésicas. Métodos: Se realizó una revisión no sistemática de la literatura en las siguientes bases de datos: Pubmed/Medline, LILACS, ScienceDirect. Resultados: La falla cardiaca con fracción de eyección preservada es una entidad común con una prevalencia entre 36,9 % y más del 50 % del total de pacientes. La fisiopatología incluye alteraciones diastólicas del ciclo cardiaco incluyendo las fases de relajación y de compliance ventricular. Desde el punto de vista anestésico se debe mantener el ritmo sinusal en arritmias, controlar la respuesta cronotrópica, evitar congestión pulmonar, manejar específicamente las etiologías-comorbilidades, conservar presiones de llenado ventricular y lograr estabilidad hemodinámica. Conclusión: Los pacientes con este síndrome representan un reto anestésico. El manejo incluye tratamiento específico de las etiologías, comorbilidades y fenotipos. A diferencia de la falla cardiaca con fracción de eyección reducida, no existen terapias que disminuyan la mortalidad, por lo que se requieren nuevos fármacos y estudios clínicos que mejoren las perspectivas anestésicas y el abordaje terapéutico.

Abstract: Heart failure with preserved ejection fraction (HFPEF) is frequent and challenging to manage in the adult population during the perioperative period. It is a complex clinical syndrome with structural and functional cardiac abnormalities with left ventricular preserved ejection fraction (LVPEF) ≥ 50%. Biomarkers, echocardiography, cardiac catheterization, and other noninvasive methods confirm the diagnosis. Currently, there is no specific effective management compared to failure with reduced LVPEF. Aim: To prepare a literature review of HFpEF and its anesthetic implications. Methods: A non-systematic literature review was carried out in the following databases: Pubmed/Medline, LILACS, ScienceDirect. Results: HFpEF is a common entity with a prevalence between 36.9 % and more than 50 % of all patients. The pathophysiology includes diastolic alterations of the cardiac cycle, including relaxation and ventricular compliance phases. From the anesthetic point of view, sinus rhythm should be maintained in arrhythmias, chronotropic response controlled, pulmonary congestion avoided, etiologies/comorbidities specifically managed, ventricular filling pressures preserved, and hemodynamic stability achieved. Conclusion: Patients with HFPEF represent an anesthetic challenge. Management includes specific treatment of etiologies, comorbidities, and phenotypes. Unlike heart failure with reduced ejection fraction, there are no therapies that reduce mortality, so new drugs and clinical studies are required to improve anesthetic prospects and therapeutic management.

Resumo: Introdução: A falência cardíaca de ejecção preservada é frequente e de difícil abordagem perio-peratória na população adulta. É uma síndrome clínica complexa com alterações estruturais e funcionais cardíacas de ejeção do ventrículo esquerdo preservada (FEVI) ≥ 50 %. Os biomarcadores, a ecocardiografia, o cateterismo cardíaco e outros métodos não invasivos confirmam o diagnóstico. Atualmente, não há manejo específico efetivo comparado à da falência com FEVI reduzida. Objetivo: Elaborar uma revisão da literatura sobre falência cardíaca com fração de ejeção preservada e suas implicações anestésicas. Métodos: Foi realizada uma revisão não sistemática da literatura nas bases de dados: PubMed/Medline, LILACS, ScienceDirect. Resultados: A falência cardíaca com fração de ejeção preservada é uma entidade comum com uma prevalência entre 36,9 % e mais de 50 % do total de pacientes. A fisiopatologia inclui alterações diastólicas do ciclo cardíaco incluindo as fases de relaxamento e de complacência ventricular. Do ponto de vista anestésico, deve-se manter o ritmo sinusal em arritmias, controlar a resposta cro-notrópica, evitar congestão pulmonar, lidar em específico com as etiologias-comorbidades, conservar pressões de fibrilação ventricular e atingir estabilidade hemodinâmica. Conclusão: Os pacientes com essa síndrome representam um desafio anestésico. O manejo inclui tratamento específico das etiologias, comorbidades e fenótipos. À diferença da falência cardíaca com fração de ejeção reduzida, não existem terapias que diminuam a mortalidade; portanto, são exigidos novos fármacos e estudos clínicos que melhorem as perspectivas anestésicas e a abordagem terapêutica.

Study of Diastolic Function in Asymptomatic Type 2 Diabetes Patients Visiting Goa Medical College and Hospital, Bambolim, Goa

Diabetes mellitus increases the risk of heart failure even in the absence of other co-morbidities. The present study is done to assess the diastolic dysfunction in diabetic patients and in correlating the grade of dysfunction with various parameters like age, gender, sex, glycaemic control, and microangiopathies associated with diabetes. We wanted to determine as to whether there is an association between diastolic dysfunction and type 2 DM and quantify the relation of LV diastolic dysfunction with age, duration of DM, HbA1c and obesity indices. We also wanted to assess the correlation between diastolic dysfunction and other microvascular complications of type 2 diabetes. METHODSThis is a cross sectional study. The sample size was 75. Assessment of the mitral peak velocity of early filling (E) and early diastolic mitral annular velocity (e’), and (E / e’) ratio is used to measure diastolic dysfunction. study was conducted on patients admitted in Goa Medical College. RESULTSAmong 75 subjects studied, 56 subjects (74.6 %) had diastolic dysfunction. There is a correlation of duration of diabetes with grade of diastolic dysfunction with a p value of 0.001. There is a correlation of dipstick proteinuria with grades of diastolic dysfunction with a p value of 0.002. Mean HbA1c in patients with grade 0 dysfunction was 7.93 with standard deviation of 0.86, grade 1 dysfunction was 7.28 with a standard deviation of 0.71, grade 2 dysfunction was 9.72 with standard deviation of 1.86, grade 3 dysfunction was 11.94 with standard deviation of 2.05 with a p value of < 0.001. CONCLUSIONSDiabetes is an independent risk factor for cardiovascular disease in the form of diastolic dysfunction in the initial stages. The grade of dysfunction was proportional to duration of diabetes, blood sugar levels, and mean HbA1c. Diastolic dysfunction also correlates with other microvascular complications of diabetes.

Disfunción diastólica y relación con arritmias: un vínculo más allá de la fibrilación auricular / Diastolic dysfunction and its relationship with arrhythmias: more than just linked to atrial fibrillation

Resumen Introducción: La falla cardíaca es un problema de salud pública, cuya prevalencia aumenta con la edad. Hasta el 50% de los casos tiene fracción de eyección preservada. Pocos estudios evalúan arritmias en este tipo de población. Se conoce una asociación con fibrilación auricular, pero se ignora qué otro tipo de arritmias pueden estar presentes. Objetivo: Describir arritmias por medio de monitorización Holter de 24 horas en pacientes con disfunción diastólica. Materiales y métodos: Se realizó un estudio observacional, descriptivo y retrospectivo, en el que se evaluaron y compararon los parámetros de la monitorización Holter de 24 horas en pacientes con disfunción diastólica, provenientes de un solo centro y residentes en Medellín, durante el año 2017. Resultados: 67 pacientes tenían disfunción diastólica; la mayoría correspondió a mujeres (65.7%). El promedio de edad fue 71 años, el índice de masa corporal fue de 26,8 y las comorbilidades más frecuentes fueron hipertensión arterial (68,7%), fibrilación auricular (19,4%) y enfermedad coronaria (19,4%). El promedio de fracción de eyección fue de 58%; el 67,2% tenía disfunción diastólica tipo I y el promedio del volumen de la aurícula izquierda fue de 33 ml/m2. Las arritmias más frecuentes fueron taquicardia atrial no sostenida (40,3%), fibrilación auricular (10,4%), taquicardia ventricular monomórfica (7,5%) y taquicardia por reentrada intranodal (1.5%). Se presentó bloqueo AV de primer grado (22,4%) y bloqueo sinoatrial (1,5%). El promedio de variabilidad de la frecuencia cardíaca fue 126.23. Conclusiones: En pacientes con disfunción diastólica tipo I y II se documentaron varios tipos de arritmias más allá de la fibrilación auricular. No hubo alteraciones en la variabilidad de la frecuencia cardíaca y tampoco en el tiempo de QTc. Dada la existencia de trasfondo fisiopatológico común, se debe evaluar en estudios futuros la relación entre arritmias y disfunción diastólica, además de su potencial tratamiento y modificación de su curso clínico.

Abstract Introduction: Heart failure is a public health problem, with a prevalence that increases with age. Up to 50% of cases have a preserve ejection fraction. Few studies have evaluated arrhythmias in this population type. It is known that there is an association with atrial fibrillation, but other types of arrhythmias that could be present are ignored. Objective: To describe arrhythmias using 24 hour Holter monitoring in patients with diastolic dysfunction. Materials and methods: An observational, descriptive, and retrospective study was performed in which the parameters from 24 hour Holter monitoring were evaluated and compared in patients with diastolic dysfunction from a single centre and resident in Medellin, during the year 2017. Results: A total of 67 patients had diastolic dysfunction, in which the majority (65.7%) were women. The mean age was 71 years, with a mean body mass index of 26.8. The most frequent comorbidities were arterial hypertension (68.7%), atrial fibrillation (19.4%), and coronary disease (19.4%). The mean ejection fraction was 58%; 67.2% had a type I diastolic dysfunction, and the mean atrial volume was 33 ml/m2. The most common arrhythmias were discontinuous atrial flutter (40.3%), atrial fibrillation (10.4%), monomorphic ventricular tachycardia (7.5%) and nodal re-entrant tachycardia (1.5%). First degree AV block (22.4%) and sinoatrial block (1.5%) were observed. The mean heart rate variability was 126.23. Conclusions: Several types of arrhythmias other than atrial fibrillation were documented in patients with type I and type II diastolic dysfunction. There were no changes in the heart rate variability or in the QTc time. Given the existence of a common pathophysiological background, further studies are needed in order to evaluate the relationship between arrhythmias and diastolic dysfunction, as well as any potential treatment and modification of its clinical course.

Clinical profile of patients presenting with heart failure with preserved ejection fraction

Background: Evaluate the clinical profile of patients presenting with heart failure having normal or preserved ejection fraction and to determine the prevalence of comorbid illnesses in these patients.Methods: The study was carried out on patients that presented with heart failure at the Vadilal Sarabhai hospital, Ahmedabad between September 2014-2016. Heart failure patients with normal ejection fraction (>50%) were selected. Socio-demographic, vital signs, data of 2D Echocardiography and Tissue Doppler study were collected. The patients were classified as per the Echocardiographic study into four categories. Different laboratory parameters were compared in patients with respect to (a) grade of Hypertension (b), grade of anemia (c), HbA1c levels. Statistical analysis was done using the SPSS software v20. Mann-Whitney and Kruskal-Wallis tests were performed to compare the means between different study groups.Results: Out of the 70 patients, a majority (47%) belonged to the Grade 2 (pseudo-normalized) group of diastolic dysfunctions with most of them having only dyspnea and pedal edema (33%). 58.6% patients required intensive care for at least one day. Regarding co-morbidities 27 (38.6%) had hypertension, 34 (48.6%) were diabetic and 49(70%) had anemia. Patients with higher grade of dysfunction had higher HbA1c (p=0.023) and worsening anemia (p=0.003).Conclusions: Authors concluded that it is of prime importance to find, prevent and treat the comorbidities along with targeted therapies for HFpEF. Further evaluation can be done for clinical applicability of different markers including HbA1c and U.ACR for renal dysfunction in HFpEF.

Physiopathological and diagnostic aspects of cirrhotic cardiomyopathy / Aspectos fisiopatológicos y diagnósticos de la miocardiopatía cirrótica

Abstract Cirrhotic cardiomyopathy is characterized by the presence of structural and functional cardiac alterations in patients suffering from hepatic cirrhosis, without previously known cardiac causes that may explain it. Clinically, it is characterized by the presence of variable grades of diastolic and systolic dysfunction (SD), alterations in the electric conductance (elongation of corrected QT interval) and inadequate chronotropic response. This pathology has been related to substandard response in the management of patients with portal hypertension and poor outcome after transplant. Even when the first description of this pathology dates back from 1953, it remains a poorly studied and frequently underdiagnosed entity. Echocardiography prevails as a practical diagnostic tool for this pathology since simple measurements as the E/A index can show diastolic dysfunction. SD discloses as a diminished ejection fraction of the left ventricle and the latent forms are detected by echocardiography studies with pharmacological stress. In recent years, new techniques such as the longitudinal strain have been studied and they seem promising for the detection of early alterations.

Resumen La miocardiopatía cirrótica se caracteriza por la presencia de alteraciones cardiacas estructurales y funcionales en pacientes con cirrosis hepática, sin que existan otras causas de enfermedad cardiaca. Clínicamente se caracteriza por la presencia de grados variables de disfunción diastólica y sistólica, alteraciones de la conducción eléctrica (prolongación del intervalo QT) y respuesta cronotrópica inapropiada. Esta patología se ha relacionado con desenlaces clínicos adversos, mala respuesta en el manejo de la hipertensión portal y resultados desfavorables posterior a trasplante hepático ortotópico. A pesar de que las primeras descripciones datan de 1953, es una entidad poco estudiada y frecuentemente subdiagnosticada. El ecocardiograma es una herramienta de diagnóstico importante en esta entidad. Mediciones simples como el índice E/A pueden traducir disfunción diastólica. La disfunción sistólica se manifiesta con disminución de la fracción de eyección del ventrículo izquierdo y las formas latentes se detectan mediante estudios de ecocardiografía con estrés farmacológico; en los últimos años se han estudiado otras técnicas como el strain longitudinal, que parecen prometedoras en la detección de alteraciones tempranas.

Cardiovascular dysfunction in patients of cirrhosis of liver

Background: Cirrhosis of liver refers to a progressive condition that disrupts the normal architecture of the liver. It is increasingly recognized that cirrhosis per se can cause cardiac dysfunction. The aim was to assess cardiovascular dysfunction electrocardiographically and echocardiographically in patients with cirrhosis of liver and to find the correlation between cardiovascular dysfunction and severity of liver cirrhosis as per child-PUGH score.Methods: Total 90 patients of cirrhosis of liver of both sexes were included in this cross-sectional study conducted from January 2018 to August 2019 in SGRDIMSR, Sri Amritsar. The severity of liver cirrhosis was assessed as per Child Pugh Score. QTc interval was calculated by Bazett抯 formula. Systolic and Diastolic dysfunction was seen on 2D-echocardiography.Results: QTc interval increased linearly with the severity of liver cirrhosis. Mean values of QTc in Child Pugh Class A=425.00(�.97), Class B=437.35(�.60), Class C=479.71(�.48) with p value of 0.04 which is significant. Diastolic dysfunction was also related with the severity of liver cirrhosis. In Child Pugh Class A= 2(33%) patients had grade 1 diastolic dysfunction, Class B=23(59%) patients had grade 1 diastolic dysfunction while in Child Pugh Class C=3(7%) had grade 1 diastolic dysfunction, 33(73%) patients had grade 2 diastolic dysfunction and 1(2%) patients had grade 3 diastolic dysfunction with p value of 0.04 which is significant. Systolic function was found normal in all the patients.Conclusions: Diastolic dysfunction and QTc interval prolongation are both related with the severity of liver cirrhosis and are major criteria of cirrhotic cardiomyopathy.
