ABSTRACT
Objective: Nitroglycerin is a first-line treatment for hypertensive acute heart failure syndrome (AHFS). However, nicardipine is frequently used to treat hypertensive emergencies, including AHFS. In this study, we compared the effectiveness of nicardipine and nitroglycerin in patients with hypertensive AHFS.Patients and Methods: This single-center, retrospective, observational study was conducted at the intensive care unit of a Japanese hospital. Patients diagnosed with AHFS and systolic blood pressure 140 mmHg on arrival between April 2013 and March 2021 were included. The outcomes were the time to optimal blood pressure control, duration of continuous infusion of antihypertensive agents, duration of positive pressure ventilation, need for additional antihypertensive agents, length of hospital stay, and body weight changes. Outcomes were compared between the nicardipine and nitroglycerin groups. We also compared these outcomes between the groups after excluding patients who received renal replacement therapy.Results: Fifty-eight patients were enrolled (26 and 32 patients were treated with nitroglycerin and nicardipine, respectively). The nicardipine group had a shorter time to optimal blood pressure control (2.0 [interquartile range, 2.0–8.5] h vs. 1.0 [0.5–2.0] h), shorter duration of continuous anti-hypertensive agent infusion (3.0 [2.0–5.0] days vs. 2.0 [1.0–2.0] days), less frequent need for additional anti-hypertensive agents (1 patients [3.1%] vs. 11 patients [42.3%]), and shorter length of hospital stay (17.5 [10.0–33.0] days vs. 9.0 [5.0–15.0] days) than the nitroglycerin group. The duration of positive pressure ventilation and body weight changes were similar between the groups. The outcomes were similar after excluding patients who received renal replacement therapy.Conclusion: Nicardipine may be more effective than nitroglycerin for treating hypertensive AHFS.
ABSTRACT
Takotsubo syndrome (TTS) is an acute and mostly reversible cardiomyopathy that mimics an acute coronary syndrome with systolic dysfunction of left ventricular.Although supraphysiological epinephrine levels have been associated with TTS, the detailed pathophysiology is incompletely understood.According to the distribution of left ventricular wall motion abnormalities, various morphological subtypes have been identified.The ultimate diagnosis depends on cardiac imaging with left ventricular angiography during acute heart catheterization, as well as echocardiography and cardiac magnetic resonance.Management is based on observational data, while randomized multicenter studies are still lacking.Mechanical circulatory support is an emerging strategy for patients with TTS and shock, in order to avoid catecholamines and inotropes in particular.This review provides a general overview of TTS.However, the demographic characteristics, diagnosis, treatment and prognosis of TTS have not been well studied in children.
ABSTRACT
Objective:To investigate the effects of intervention mapping on cardiopulmonary function for patients with acute heart failure in compensatory period, so as to provide references for their early rehabilitation activities.Methods:A total of 90 patients with acute heart failure admitted to Fuwai Central China Cardiovascular Hospital from October 2018 to October 2019 were enrolled in the present study. They were divided into experimental group and control group according to draw-lots-method, with 45 cases in each group. The control group received the routine care and activity plan, while the experimental group implemented intervention mapping-based stage early rehabilitation program. The indicators included 6MWT, forced expiratory volume in one second (FEV 1), brain natriuretic peptide (BNP) as well as Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the intervention effects were compared between the two groups. Results:There were no significant differences in FEV 1, 6MWT, BNP and MLHFQ scores between the two groups at admission ( P>0.05). On discharge, FEV 1, 6MWT were (2.17±0.44) L, (273.09±55.80) m in the experimental group, significantly higher than (1.94 ± 0.39) L and (236.44 ± 50.99) m in the control group; the plasma BNP were (676.79 ± 78.75) ng/L in the experimental group, significantly lower than (736.05 ± 78.77) ng/L in the control group; in addition, the physical demention, emotional dimenson, other demension scores and total scores of MLHFQ in the experimental group were (65.39 ± 5.02), (67.56 ± 4.99), (66.05 ± 4.16) and (66.33 ± 2.63) points, significantly higher than (59.79 ± 5.94), (64.33 ± 5.93), (62.76 ± 4.47), (62.36 ± 2.98) points in the control group, the differences were statistically significant ( t values were 2.56-6.51, all P<0.05). Conclusions:Designing and implementing stage early rehabilitation program using intervention mapping can promote cardiopulmonary function and quality of life of patients with acute heart failure in compensatory period.
ABSTRACT
RESUMEN Introducción: Las teorías físicas y matemáticas han permitido el desarrollo de nuevas metodologías diagnósticas de la dinámica cardiaca. Entre estas se encuentra la evaluación de las proporciones de la entropía proporcional para diferenciar la normalidad de la enfermedad cardiaca, aunque su capacidad diagnóstica debe comprobarse en escenarios clínicos críticos específicos, como en la falla cardiaca y el infarto agudo de miocardio. Objetivo: Describir evaluaciones diagnósticas de la dinámica cardiaca en pacientes con infarto agudo de miocardio o falla cardiaca aguda. Métodos: En un estudio a doble ciegos con 20 Holter, 5 normales, 8 con falla cardiaca aguda y 7 con infarto agudo de miocardio, se aplicó un método fundamentado en las proporciones de la entropía tomando los valores máximos y mínimos de la frecuencia cardiaca y el número total de latidos por hora, en un mínimo de 18 horas, generando un atractor numérico. Se evaluó cada dinámica con base en la entropía y sus proporciones. Finalmente, se comparó la precisión diagnóstica del método matemático con respecto al diagnóstico clínico convencional. Resultados: Se diferenciaron matemáticamente los casos normales y patológicos mediante la evaluación en 18 horas con el método descrito, encontrando valores de sensibilidad y especificidad del 100 % y un coeficiente Kappa de uno, indicando una concordancia diagnóstica perfecta del método matemático con respecto al diagnóstico clínico. Conclusiones: Las proporciones de la entropía permiten establecer diagnósticos objetivos de la dinámica cardiaca, diferenciando matemáticamente dinámicas normales de aquellas que presentan infarto agudo de miocardio y falla cardiaca aguda.
ABSTRACT Introduction: Physical and mathematical theories have allowed the development of new diagnostic methodologies of cardiac dynamics, as one based on the evaluation of entropy proportions to differentiate normality from cardiac disease, although its diagnostic capacity must be yet determined in specific critical scenarios as acute heart failure and acute myocardial infarction Objective: To describe diagnostic evaluations of cardiac dynamics in patients diagnosed with acute myocardial infarction or acute heart failure. Methods: A blind study was developed with 20 Holter registries; 5 normal, 8 with acute cardiac failure and 7 with acute myocardial infarction. Then, a method based on the proportions of the entropy of the numerical attractors was applied. The maximum and minimum values of the heart rate and the total number of beats per hour were taken for at least 18 hours, with which numerical attractors were generated, which measure the probability of consecutive heart rate pairs. An evaluation of all dynamics was made based on the entropy and its proportions. Finally, a comparison between the diagnostic precision of the mathematical method with respect to the conventional clinical diagnosis was performed. Results: Normal cases were mathematically differentiated from the pathological ones through the evaluation of Holter registries for 18 hours, achieving values of sensitivity and specificity of 100% as well as a Kappa coefficient of 1, indicating a perfect diagnostic concordance between the mathematical method to diagnose the cardiac dynamics with respect to the clinical diagnosis. Conclusions: The proportions of entropy allow to establish objective diagnoses of cardiac dynamics, mathematically differentiating normal dynamics from those with acute myocardial infarction and with acute cardiac failure.
ABSTRACT
Resumen La insuficiencia cardíaca aguda descompensada (ICAD) es una causa común de hospitalización, con repercusiones significativas en los sistemas de salud. El manejo agudo se basa en la reducción de la volemia con diuréticos de asa, sin embargo, un porcentaje de pacientes presenta resistencia o no logra la respuesta clínica esperada con este tratamiento. Una de las medidas que ha comprobado ser efectiva en este contexto, es el uso de solución salina hipertónica (SSH) en conjunto con dosis altas de diuréticos de asa, como medida terapéutica temida por sus posibles repercusiones sobre la función renal y posible sobrecarga de sodio. Objetivos: Determinar si el uso de solución salina hipertónica en pacientes con falla cardiaca aguda e hipervolemia genera un deterioro de la función renal. Determinar la respuesta del Pro-BNP ante el uso de la solución salina hipertónica en pacientes con falla cardiaca aguda como marcador de respuesta terapéutica. Determinar si el uso de solución salina hipertónica aumenta la diuresis sin generar cambios importantes en el sodio. Se muestran datos de pacientes con insuficiencia cardiaca aguda descompensada, que tras no presentar mejoría con altas dosis de diurético de asa en bolo, se les aplicó la solución hipertónica como adyuvante a este tratamiento. Se toma un total de 26 pacientes analizando datos generales clínicos y de laboratorio, se valoran curvas con la respuesta diurética y por parámetros de laboratorio a las 48 y 72 horas. El uso de solución salina hipertónica consigue un aumento de más de un 200% de la diuresis en 24 horas, con un descenso del Pro BNP de más de un 60% a las 48 horas, sin mostrar un cambio importante en los niveles de creatinina, nitrógeno ureico y sodio. Se requirió reposición de potasio en la totalidad de los pacientes. Se concluye que la infusión de furosemida más solución hipertónica es efectiva tanto en disminuir niveles de NT Pro-BNP en los pacientes, como en generar un aumento en el volumen de diuresis. La principal complicación fue la hipokalemia, sin cambios considerables en el valor de sodio, creatinina y nitrógeno ureico séricos.
Abstract Uso de Solución Hipertónica en pacientes con insuficiencia cardiaca aguda como terapia adyuvante a altas dosis de diuréticos Acute decompensated heart failure (AHF) is a common cause of hospitalization, with significant repercussions on health systems. Acute management is based on the reduction of blood volume with loop diuretics; however, a percentage of patients show resistance or do not achieve the expected clinical response with this treatment. One of the measures that has proven to be effective in this context is the use of hypertonic saline (HSS) in conjunction with high doses of loop diuretics, as a therapeutic measure feared due to its possible repercussions on kidney function and possible sodium overload. Objetives: To determine if the use of hypertonic saline in patients with acute heart failure and hypervolemia leads to a deterioration in renal function. To determine the response of Pro-BNP to the use of hypertonic saline in patients with acute heart failure as a marker of therapeutic response. Determine if the use of hypertonic saline increases urine output without causing significant changes in sodium. Data are shown from patients with acute decompensated heart failure, who after not presenting improvement with high doses of bolus loop diuretic, the hypertonic solution was applied as an adjunct to this treatment. A total of 26 patients are taken analyzing general clinical and laboratory data, curves with the diuretic response and by laboratory parameters are evaluated at 48 and 72 hours. The use of hypertonic saline solution achieves an increase of more than 200% in diuresis in 24 hours, with a decrease in Pro BNP of more than 60% at 48 hours, without showing a significant change in creatinine levels, urea nitrogen and sodium. Potassium replacement was required in all patients. It is concluded that the infusion of furosemide plus hypertonic solution is effective both in reducing levels of NT Pro-BNP in patients, and in generating an increase in the volume of diuresis. The main complication was hypokalemia, without significant changes in serum sodium, creatinine, and urea nitrogen.

Acute heart failure (AHF) is a common critical illness in pediatrics.At present, there is a lack of evidence-based diagnosis and drugs for children with AHF.Besides, there is a paucity of reliable evidence on the effectiveness and safety of technologies and drugs for the management of AHF in children.Moreover, the innovation is absent from the treatment theory.Furthermore, the consensus or guidelines on the management of children with AHF are out of date.Therefore, there are huge challenges in the clinical management of children with AHF.In recent years, new drugs and technologies have been applied in the diagnosis and treatment of children with AHF.For example, calcium sensitizers have gradually attracted attention in the treatment of children with AHF, blood purification and extracorporeal membrane oxygenation can significantly improve the prognosis of some children with AHF.Therefore, a multi-center, large sample high-quality and randomized control study is still required to guide the clinical management of children with AHF.
ABSTRACT
Objective:To investigate the clinical diagnostic value of soluble leukocyte differentiation antigen 14 subtype (sCD14-ST, presepsin) in elderly patients with acute left heart failure (AHF) complicated with bacterial pneumonia.Methods:The data of 111 elderly patients with acute left heart failure complicated with bacterial pneumonia or acute left heart failure (the control group) who were admitted into emergency department from August 2017 to August 2018 were retrospectively analyzed. Chemilluminescence immunoassay was performed to detect presepsin in all patients. And meanwhile, fever or not, presepsin, procalcitonin (PCT), C-reaction protein (CRP) and other clinical data were compared between the two groups. Univariate and multivariate logistic regression analysis were adopted to screen the risk factor influencing the diagnosis. The receiver operating characteristic (ROC) curve was used to analyze the clinical value of presepsin on diagnosing acute left heart failure complicated with bacterial pneumonia in elderly patients.Results:Presepsin of the group complicated with bacterial pneumonia was significantly higher than that of the control group [(500.9±283.5) ng/L vs. (167.7±102.3) ng/L, t=-7.902, P=0.000]. The logistic regression analysis, showed that fever, presepsin and procalcitonin were independent risk factors for AHF combined with bacterial pneumonia diagnosis. The area under ROC curve (AUC) of presepsin, PCT and WBC was 0.887 (95% CI: 0.825-0.949, P<0.001), 0.794(95% CI: 0.704-0.885, P<0.001), and 0.566 (95% CI: 0.455-0.678, P=0.231), respectively. The optimal threshold value of presepsin was 227 ng/L, the sensitivity was 82.0%, specificity was 83.6%, the positive likelihood ratio was 5, the negative likelihood ratio was 0.22, the positive predictive value) was 80.4%, and the negative predictive value was 85%. Conclusions:Presepsin has an important diagnostic value for the identification of AHF combined with bacterial pneumonia in elderly patients.

Congestive cardiac failure (CCF) is a worldwide phenomenon and affects millions of people years and is accompanied with high mortality. The present review is undertaken to evaluate the usefulness of Lung Ultrasound Scan in diagnosis and to identify its role as a marker of clinical outcome in patients with Acute LVF. A review of literature was done to find the role of lung ultrasound and clinical congestion score in acute left ventricular failure from search engines such as PubMed, google scholar. Major exclusion criteria were the studies that included patients with Right Ventricular Failure, renal insufficiency, other respiratory causes of breathlessness like pneumonia, pulmonary embolism, pneumothorax and pleural effusion. This review concluded that lung ultrasonography is as a rapid, non-invasive, bedside tool for the diagnosis and risk assessment of pulmonary congestion in Acute LVF.
ABSTRACT
Background: Acute heart failure (AHF) is a common and growing medical problem associated with major morbidity and mortality. It is the leading reason for hospital admission among patients over age 65 years. Not much of data is available from India, there are a lot of differences between the western data and available Indian data. Prompt diagnosis, identification of reversible causes and supportive management in ICU is of paramount importance.Methods: This study was conducted at Sri Jayadeva Institute of Cardiovascular Sciences and Research, Bangalore, Karnataka after the institutional ethics committee approval. Those patients who were diagnosed to have AHF, were evaluated and treated as per the institution protocols in ICU and standard medical care which includes diuretics, inotropes and vasopressors. All the patients were prospectively studied; investigated for the etiology of AHF.Results: Majority of patients presenting as Acute Heart Failure are of 60 years mean age, with 63% males. Ischemic heart disease is the leading cause of Acute Heart Failure. Shortness of breath was the commonest presentation followed by crackles. Abdominal pain was the most common (28%) non cardiac symptom. There is no significant correlation between the presence of anemia and mortality. Hyponatremia had relation with mortality. 22% had HFpEF, rest had HFrEF. The mean hospital stay was 8.3 days. The study mortality was 9 % and the 30-day mortality was 13 % in our study.Conclusions: Current available data from Indian studies and registries has a lot of difference from the western data with regards to causes, response to treatment, and more such data is needed to frame regional guidelines for better understanding of presentation of heart failure ,treatment and risk factors for mortality.
ABSTRACT
Resumen Introducción: la estimación temprana del riesgo en falla cardiaca aguda puede ayudar en la toma de decisiones clínicas. Objetivo: identificar los factores de riesgo asociados a mortalidad intrahospitalaria en pacientes con falla cardiaca aguda. Métodos: análisis de una cohorte retrospectiva de pacientes mayores de 18 años ingresados a hospitalización por falla cardiaca aguda en un hospital de tercer nivel, entre los años 2012 y 2016. Resultados: se incluyeron 247 pacientes, con edad promedio de 62,8 años; predominó el sexo masculino con un 60%. El 84% de los pacientes tenía falla cardiaca con fracción de expulsión disminuida (mediana de 25%). La mortalidad intrahospitalaria fue de 9,3% y la acumulada a 30 días y 6 meses posterior al egreso hospitalario fue de 10,9 y 14,1%, respectivamente. Los dos predictores asociados a muerte intrahospitalaria fueron el nitrógeno ureico en sangre (BUN)> 37 mg/dl (OR: 10,8; 95% IC: 4,10-28,8) y la presión arterial sistólica (PAS) ≤ 125 mm Hg (OR: 3,42; 95% IC:1,15-10,0). El modelo de árbol de regresión y clasificación (CART) identificó como el mejor predictor de mortalidad los niveles elevados de BUN (≥ 32,5 mg/dl), seguido por la presión sistólica disminuida (< 97 mm Hg) y finalmente por los niveles elevados de creatinina (≥ 1,75 mg/dl). Conclusión: el análisis mediante el CART permite clasificar en forma temprana la probabilidad de muerte por un árbol de riesgo que incluye el BUN ≥ 32,5 mg/dl, la presión sistólica < 97 mm Hg y los niveles de creatinina ≥ 1,75 mg/dl.
Abstract Introduction: The early estimation of risk in acute heart failure may help in the taking of clinical decisions. Objective: To identify the risk factors associated with in-hospital mortality in patients with acute heart failure. Methods: An analysis was performed on a retrospective cohort of patients greater than 18 years admitted to a tertiary hospital due acute heart failure between the years 2010 and 2016. Results: A total of 247 patients were included, with a mean age of 62.8 years, and of which 60% were male. The large majority (84%) of the patients had heart failure with a reduced ejection fraction (median 25%). The in-hospital mortality was 9.3%, and the accumulated rate at 30 days and 6 months after hospital discharge was 10.9% and 14.1%, respectively. The two predictors associated with in-hospital death was a blood urea nitrogen (BUN) > 37 mg/dL (OR: 10.8; 95% CI: 4.10-28.8) and a systolic blood pressure (SBP) ≤ 125 mmHg (OR: 3.42; 95% CI: 1.15-10.0). The classification and regression tree (CART) model identified elevated levels of as the best predictor of mortality, followed by a decreased systolic pressure (< 97 mmHg), and finally due to elevated creatinine levels (≥ 1,75 mg/dL). Conclusion: The analysis using the classification and regression tree (CART) model can provide an early classification of the probability of death by a risk tree that includes BUN ≥ 32.5 mg/dL, systolic pressure <97 mm Hg, and creatinine levels ≥ 1.75 mg/dL.

ObjectiveThe assessment of volume load status in patients with acute heart failure is of great significance for preventing volume overload. The aim of this study was to explore the predictive value of NT-proBNP level and IVC-CI on volume load and prognosis in patients with acute heart failure. MethodsFrom January 2017 to April 2019, the clinical characteristics of 98 patients with acute heart failure diagnosed and treated in the Peking University People's Hospital were retrospectively reviewed in this study. All of them were treated with routine anti-heart failure treatment. According to the level of relative volume balance, they were divided into volume overload group (65 cases) and non-volume overload group (33 cases). All the patients were followed up for 30 days after discharge. The patients with death and cardiogenic rehospitalization were included in the event group (30 cases), and the rest were in the non-event group (68 cases). NT-proBNP and IVC-CI in different volume load groups and different prognosis groups were compared. The volume index levels (serum albumin, hemoglobin, hematocrit, PCWP, CVP) of patients in different volume load groups were compared. The effects of NT-proBNP and IVC-CI on volume load and prognosis of patients were analyzed.ResultsThe levels of NT-proBNP [（1306.39±313.98）pg/mL], PCWP [（19.63±1.95）mmHg] and CVP [（14.65±1.03）cmHg] in the volume overload group were higher than those in the non-volume overload group, while the IVC-CI [（38.26±8.14）%], albumin [（16.23±2.12）g/L], hemoglobin and hematocrit [（36.26±2.78）%] in the volume overload group were lower than those in the non-volume overload group (P0.05). On discharge, the AUC of NT-proBNP, IVC-CI in predicting patients with acute heart failure was respectively 0.806 and 0.847. Although the prediction accuracy was relatively high, the AUC of combined prediction was 0.982, which was significantly higher than that of NT-proBNP and IVC-CI (Z=3.589, 3.274, both P<0.05).Conclusion There is a correlation between NT-proBNP, IVC-CI and volume indexes. The combined detection of NT-proBNP and IVC-CI can help to assess the volume load status of patients with acute heart failure and improve the predictive value of short-term prognosis of patients.
ABSTRACT
La insuficiencia cardiaca aguda (ICA) se define como la aparición rápida o el empeoramiento de los síntomas o signos de IC. Es una entidad potencialmente mortal que requiere evaluación y tratamiento urgentes y típicamente conlleva la hospitalización urgente. La descompensación de la insuficiencia cardiaca crónica puede ocurrir sin que existan factores desencadenantes conocidos. Se produce una disfunción endotelial que puede deberse a un desequilibrio en el medio neuro-hormonal, inflamatorio, y oxidativo en la circulación y en las células endoteliales. Se produce clínicamente hipoperfusión miocárdica, reducción del flujo coronario, disfunción isquémica, aumento de la rigidez vascular y deterioro de la distensibilidad arterial que agravan en mayor medida la lesión miocárdica. La evaluación inicial y la monitorización no invasiva continua de las funciones vitales cardiorrespiratorias son esenciales. Los diuréticos son la piedra angular del tratamiento de los pacientes con ICA y signos de sobrecarga de fluidos y congestión. La terapia de reemplazo renal se debe reservar para pacientes que no responden al tratamiento con diuréticos. Los vasodilatadores intravenosos son los segundos fármacos más utilizados en la ICA para el alivio de los síntomas; sin embargo, no existen pruebas definitivas que confirmen su efecto beneficioso. El uso de inotrópicos debería estar reservado a los pacientes con disfunción sistólica que afecta a la perfusión de órganos vitales. Los dispositivos de asistencia ventricular y otras formas de asistencia mecánica circulatoria pueden emplearse como tratamiento puente en pacientes seleccionados(AU)
Acute heart failure (AHF) is defined as the rapid onset or worsening of the symptoms or signs of heart failure. It is a potentially fatal entity that requires urgent evaluation and treatment and typically involves urgent hospitalization. Decompensation of chronic heart failure can occur without known triggers. An endothelial dysfunction occurs that may be due to an imbalance in the neuro-hormonal, inflammatory, and oxidative environment in the circulation and in the endothelial cells. Myocardial hypoperfusion is clinically produced, coronary flow reduction, ischemic dysfunction, increased vascular rigidity and deterioration of arterial compliance that aggravate myocardial injury to a greater extent. Initial evaluation and continuous non-invasive monitoring of vital cardiorespiratory functions are essential. Diuretics are the cornerstone of the treatment of patients with AHF and signs of fluid overload and congestion. Renal replacement therapy should be reserved for patients who do not respond to treatment with diuretics. Intravenous vasodilators are the second most used drugs in the AHF for the relief of symptoms; however, there is no definitive evidence to confirm its beneficial effect. The use of inotropics should be reserved for patients with systolic dysfunction that affects the perfusion of vital organs. Ventricular assist devices and other forms of mechanical circulatory assistance can be used as a bridge treatment in selected patients(AU)

Existe remodelamiento cardiaco, que, junto con el incremento de la masa miocárdica y del tamaño del ventrículo izquierdo y la contractilidad miocárdica disminuida agravada por los cambios del embarazo, pueden condicionar insuficiencia cardiaca aguda durante el periodo periparto. Se considera miocardiopatía periparto cuando la función sistólica del ventrículo izquierdo y los síntomas de insuficiencia cardiaca ocurren en el último mes del embarazo y en los cinco meses posteriores al parto con incidencia de 1 por cada 1300 a 15,000 embarazos. Se comunica el caso de una paciente de 26 años, con antecedente de catarata congénita, que tuvo embarazo normoevolutivo, con parto eutócico, durante el puerperio tuvo disnea y datos de hipoperfusión, mediante evaluación ultrasonográfica pulmonar y cardiaca mostró datos de miocardiopatía dilatada periparto, fue trasladada a un hospital de tercer nivel, donde a pesar del tratamiento intensivo multidisciplinario, falleció. La miocardiopatía periparto es una enfermedad subvalorada con alta mortalidad materna y perinatal; sin embargo, la detección oportuna puede mejorar el tratamiento y el pronóstico. Con la comunicación de este caso, se pretende demostrar la importancia de la detección temprana de una afección poco diagnosticada, como es la miocardiopatía periparto.
Abstract: Pregnancy is a state that imposes a real challenge for the maternal cardiovascular system. There is a cardiac remodeling, which along with an increase in myocardial mass, in left ventricular size and decreased myocardial contractility aggravated by changes in pregnancy, can condition acute heart failure during the peripartum period. Peripartum cardiomyopathy is when the systolic function of the left ventricle and the symptoms of heart failure occur in the last month of pregnancy and in the five months after delivery with an incidence ranging from 1/1300 to 1/15,000 pregnancies. This paper reports the case of a 26-year-old female patient, who had a history of congenital cataract, with normal pregnancy and eutocic delivery; during the puerperium patient showed dyspnea, hypoperfusion data and pulmonary and cardiac ultrasonographic evaluation of peripartum dilated cardiomyopathy, being transferred at a third level, where despite intensive multidisciplinary treatment, the patient died. Peripartum cardiomyopathy is an undervalued disease that has a high maternal and perinatal mortality; however, a timely detection can improve treatment and prognosis. The purpose of this case report is to demonstrate the importance of early detection of a poorly diagnosed entity, such as peripartum cardiomyopathy.
ABSTRACT
Objective@#To explore the role of late gadolinium enhancement (LGE) and T1 mapping for detection of cardiac amyloidosis.@*Methods@#Nine cases of cardiac amyloidosis who had diagnosed by renal biopsy diagnosed type light-chain (AL) amyloidosis and acute heart failure suspected involvement of the heart in Tianjin First Central Hospital from May 2018 to March 2019 were enrolled, and at the same time 14 cases of non-obstructive hypertrophic cardiomyopathy patients, 12 cases of healthy physical examination at the same period were enrolled as the control. All patients underwent Philips 3.0-T including plain scan as cine, T2WI, native T1 mapping and enhanced scan as perfusion, LGE imaging, post T1 mapping. For LGE cardiac magnetic resonance imaging (CMRI), a bolus of 0.1 mL/kg of gadolinium-based contrast followed by a 20 mL saline flush was administered. After a 7-minutes delay, ECG-gated images were acquired in 3 long-axis and a stack of short-axis slices identical to those of cine images using a breath-hold gradient recalled echo phase-sensitive or magnitude only inversion recovery sequence. LGE and T1 mapping CMRI observation, including cardiac function index [left ventricle end-diastolic volume (LVEDV), left ventricle end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), valvular regurgitation], cardiac morphological index [including left ventricular wall thickness, left ventricular weight (LVM)], myocardial histological characteristics and markers N-terminal pro-brain natriuretic peptide (NT-proBNP) and accompanying signs (including pericardial effusion, pleural effusion) were performed.@*Results@#The predominant LGE pattern in amyloidosis was diffuse left ventricular sub endocardial enhancement (3/9), diffuse in left ventricular wall enhancement (3/9), and transmural delayed enhancement in left ventricular (2/9) and non-typical delayed enhancement (1/9). Myocardial T1 was significantly elevated in cardiac AL amyloidosis patients compared to normal subjects and hypertrophic cardiomyopathy (ms: 1 497.3±22.0 vs. 1 273.3±30.1, 1 329.3±42.6, both P < 0.05). Myocardial T1 was increased in AL amyloid before LGE. A post-contrast myocardial T1 was significantly elevated in cardiac AL amyloidosis patients compared to normal subjects and hypertrophic cardiomyopathy (ms: 476.7±44.2 vs. 516.1±41.5, 569.9±12.3, both P > 0.05). Three of 9 amyloidosis patients with review images showing T1 value and cardiac function was no significantly different with the first check (ms: 1 484.8±6.5 vs. 1 497.3±22.0, P = 0.11).@*Conclusions@#One-stop CMRI can improve the diagnosis of cardiac amyloidosis, LGE can display the myocardial scarring and fibrosis, and T1 mapping is sensitive to myocardial edema and diffuse fibrosis. LGE and T1 mapping can improve the diagnostic accuracy, which is very meaningful for diagnosis and follow-up of patients.
ABSTRACT
Objective@#To investigate the value of pulse indicator continuous cardiac output (PiCCO) monitoring in the treatment management of patients with severe heart failure.@*Methods@#Sixty patients of severe heart failure admitted to intensive care unit (ICU) of Fujian Provincial Hospital from August 2017 to February 2019 were enrolled, and they were divided into control group and treatment group according to random number table method, with 30 in each group. The treatment group used bedside PiCCO to carry out minimally invasive hemodynamics monitoring, according to the monitoring data target guidance for vasoactive drugs and liquid management. The control group was based only on traditional electrocardiogram (ECG) monitoring and lung sound, urine volume of vasoactive drugs and liquid management. The changes of cardiac index (CI), global end diastolic volume index (GEDVI), extravascular lung water index (EVLWI), systemic vascular resistance index (SVRI), invasive mean arterial pressure (MAP) and central venous pressure (CVP) were observed before and 72 hours after treatment in the treatment group. The 7-day total effective rate, the length of ICU stay and 28-day mortality were compared between the two groups.@*Results@#Compared with before treatment, CI and MAP in the treatment group were significantly increased after treatment [CI (mL·s-1·m-2): 53.34±16.67 vs. 35.01±13.34, MAP (mmHg, 1 mmHg = 0.133 kPa): 72.6±10.6 vs. 62.5±10.3, both P < 0.05], GEDVI, EVLWI, SVRI, CVP were significantly decreased [GEDVI (mL/m2): 760.3±90.2 vs. 960.2±110.3, EVLWI (mL/kg): 6.5±1.3 vs. 12.5±6.2, SVRI (kPa·s·L-1·m-2): 297.3±35.1 vs. 434.1±58.8, CVP (mmHg): 10.1±2.6 vs. 12.2±3.4, all P < 0.05]. Compared with the control group, the 7-day total effective rate of the treatment group was significantly higher (90.0% vs. 80.0%), the length of ICU stay was significantly shorter (days: 8.2±4.5 vs. 10.3±2.5), and the 28-day mortality was significantly lower, with statistically significant difference (all P < 0.05).@*Conclusion@#PiCCO monitoring is a goal-oriented treatment management for patients with severe heart failure, which is helpful to individualized accurate treatment, shorten the length of ICU stay and improve short-term prognosis.
