ABSTRACT

ObjectiveTo investigate the association between estimated glucose disposal rate (eGDR) and the severity of coronary heart disease. MethodsWe conducted a hospital-based cross-sectional study that included 1258 patients (mean age: 62(53-68) years) who underwent coronary angiography for suspected coronary artery disease (53.9% were male). Insulin resistance level (IR) was calculated according to eGDR formula: eGDR = 21.158 - (0.09 × WC) - (3.407 × hypertension) - (0.551 × HbA1c) [hypertension (yes = 1 / no = 0), HbA1c = HbA1c (%)]. Subjects were grouped according to the eGDR quantile. CAD severity was determined by the number of narrowed vessels: no-obstructive CAD group (all coronary stenosis were<50%, n=704), Single-vessel CAD group (only one involved major coronary artery stenosis≥50%, n=205), Multi-vessel CAD group (two or more involved major coronary arteries stenosis≥50%, n=349); Multivariate logistic regression model was used to analyze the association between eGDR and CAD severity. The linear relationship between eGDR and CAD in the whole range of eGDR was analyzed using restricted cubic spline. Subgroup analyses were used to assess the association between eGDR and CAD severity in different diabetic states. Receiver operating characteristic (ROC) curve analysis were used to evaluate the value of eGDR in improving CAD recognition. ResultsA decrease in the eGDR index was significantly associated with an increased risk of CAD severity (OR: 2.79; 95%CI: 1.72~4.55; P<0.001). In multivariate logistic regression models, individuals with the lowest quantile of eGDR (T1) were 2.79 times more likely to develop multi-vessel CAD than those with the highest quantile of eGDR (T3) (OR: 2.79; 95%CI: 1.72~4.55; P<0.001). Multivariate restricted cubic spline analysis showed that eGDR was negatively associated with CAD and multi-vessel CAD (P-nonlinear>0.05). In non-diabetic patients, compared with the reference group (T3), the T1 group had a significantly increased risk of CAD (OR: 1.42; 95% CI: 1.00~2.01; P<0.05) and multi-vessel CAD (OR: 1.86; 95%CI: 1.21~2.86; P<0.05). No statistical association was found between eGDR and CAD in diabetic patients. In ROC curve analysis, when eGDR was added to traditional model for CAD, significant improvements were observed in the model's recognition of CAD and multi-vessel CAD. ConclusionOur study shows eGDR levels are inversely associated with CAD and CAD severity. eGDR, as a non-insulin measure to assess IR, could be a valuable indicator of CAD severity for population.

ABSTRACT

ABSTRACT Introduction: There is no consensus on the impact of coronary artery disease in patients undergoing transcatheter aortic valve implantation. Therefore, the objective of this study was, in a single-center setting, to evaluate the five-year outcome of transcatheter aortic valve implantation patients with or without coronary artery disease. Methods: All transcatheter aortic valve implantation patients between 2009 and 2019 were included and grouped according to the presence or absence of coronary artery disease. The primary endpoint, five-year all-cause mortality, was evaluated using Cox regression adjusted for age, sex, procedure years, and comorbidities. Comorbidities interacting with coronary artery disease were evaluated with interaction tests. In-hospital complications was the secondary endpoint. Results: In total, 176 patients had aortic stenosis and concomitant coronary artery disease, while 170 patients had aortic stenosis only. Mean follow-up was 2.2±1.6 years. There was no difference in the adjusted five-year all-cause mortality between transcatheter aortic valve implantation patients with and without coronary artery disease (hazard ratio 1.00, 95% confidence interval 0.59-1.70, P=0.99). In coronary artery disease patients, impaired renal function, peripheral arterial disease, or ejection fraction < 50% showed a significant interaction effect with higher five-year all-cause mortality. No significant differences in complications between the groups were found. Conclusion: Five-year mortality did not differ between transcatheter aortic valve implantation patients with or without coronary artery disease. However, in patients with coronary artery disease and impaired renal function, peripheral arterial disease, or ejection fraction < 50%, we found significantly higher five-year all-cause mortality.

ABSTRACT

Abstract Background: Trimethylamine N-oxide (TMAO), a gut microbiota metabolite, is associated with cardiovascular disease (CVD) development. TMAO can trigger an inflammatory response by inducing the nuclear factor-kappa B (NF-κB) signaling cascade and increasing the expression of pro-inflammatory cytokines, contributing to the worsening of CVD. This study aimed to evaluate the association between TMAO plasma levels and inflammation in patients with coronary artery disease (CAD). Methods: A cross-sectional study was carried out including 29 patients with CAD. Peripheral blood mononuclear cells (PBMC) were isolated from fasting blood samples, and NF-κB and vascular cell adhesion protein 1 (VCAM1) mRNA expression were estimated using real-time quantitative PCR. We determined TMAO plasma levels by LC-MS/MS and TNF-α by ELISA. Routine biochemical parameters were evaluated using an automatic biochemical analyzer. Correlations were estimated by Spearman or Pearson test. Statistical significance was set at the level of p < 0.05. Results: All patients presented TMAO levels within the normal range according to EUTox (normal range: 2.83 ± 1.53 mg/L; CAD patients: 0.2 [0.1 to 0.2] ng/μL). TMAO plasma levels were positively correlated with NF-κB mRNA expression (0.555; p = 0.002). Conclusion: TMAO plasma levels may be associated with NF-κB mRNA expression in patients with CAD and may contribute to the pathogenesis of this disease.

ABSTRACT

Introducción. La arteria interventricular anterior se origina en la coronaria izquierda, irriga la cara anterior de los ventrículos, el ápex y el tabique interventricular; es la segunda arteria más relevante del corazón. Objetivo. Describir las características anatómicas y clínicas de la arteria interventricular anterior mediante angiografía. Materiales y métodos. Se realizó un estudio descriptivo con 200 reportes angiográficos de personas colombianas; se valoraron el origen, el trayecto y la permeabilidad de la arteria interventricular anterior, así como la dominancia coronaria. Se incluyeron datos relacionados con dolor precordial, infarto agudo de miocardio, dislipidemia y alteración electrocardiográfica. No fue posible hacer pruebas estadísticas, debido a la escasa prevalencia de variaciones anatómicas de dicha arteria. Resultados. Se encontró una arteria interventricular anterior con su origen en el seno aórtico izquierdo, sin puente miocárdico, sin alteración de la permeabilidad y con dominancia izquierda. La frecuencia de los puentes fue del 2 % y la dominancia más frecuente fue la derecha en el 86 %. Se presentaron alteraciones de permeabilidad en el 43 % de los casos, las cuales afectaron principalmente al S13. El 25 % de los pacientes presentó dolor precordial; el 40 %, alteraciones ecocardiográficas; el 5 %, cardiopatía isquémica, y el 59 %, alguna alteración electrocardiográfica. Conclusiones. Las variaciones en el origen de la arteria interventricular anterior son poco prevalentes, según reportes de Chile, Colombia y España. Los puentes miocárdicos de esta arteria fueron escasos respecto a otros estudios, lo cual sugiere mejor especificidad de los hallazgos de la angiotomografía o de la disección directa. La permeabilidad coronaria se valora con la escala TIMI (Thrombolysis in Myocardial Infarction); puntajes de 0 y 1 indican una lesión oclusiva asociada con cardiopatía isquémica. La dominancia coronaria más frecuente, según diversas técnicas, es la derecha, seguida de la izquierda en hombres y de una circulación balanceada en mujeres.


Introduction. The anterior interventricular artery originates from the left coronary artery and irrigates the anterior surface of the ventricles, apex, and interventricular septum, making it the second most relevant artery of the heart. Objective. To describe the anatomical and clinical aspects of the anterior interventricular artery through angiography. Materials and methods. A descriptive study was conducted using 200 angiographic reports of Colombian individuals. The anterior interventricular artery's origin, course, patency, and coronary dominance were evaluated. Data related to chest pain, acute myocardial infarction, dyslipidemia, and electrocardiographic abnormalities were included. Statistical tests could not be performed due to this artery's low prevalence of anatomical variations. Results. One anterior interventricular artery was found to have originated from the left coronary sinus without a myocardial bridge, with no alteration in permeability, and with left dominance. The frequency of bridges was 2%, and the most frequent dominance was right in 86; permeability alterations occurred in 43% mainly affecting S13. Twenty-five per cent presented chest pain; 40%, echocardiographic alterations; 5%, ischemic heart disease, and 59%, electrocardiographic alterations. Conclusions. Variations of origin of the anterior interventricular artery have a low prevalence according to reports from Chile, Colombia, and Spain. anterior interventricular artery myocardial bridges were scarce compared to other studies, suggesting better specificity of computed tomography angiography or direct dissection for these findings. The assessment of coronary permeability is graded with the thrombolysis in myocardial infarction scale; values 0 and 1 indicate occlusive lesion associated with ischemic heart disease. According to various techniques, the most frequent coronary dominance the right, followed by the left in men and balanced circulation in women.

ABSTRACT

Aim: To assess the safety, efficiency, and device compatibility of the Second Generation Robotic System. Methods: Data on Robot-Assisted PCI (RePCI) is frequently insufficient in India. Many articles were published in national, non-indexed journals that are not available online and are difficult to obtain. Recognizing these constraints, the current review is intended to compile the available data on this important new innovation technique. This review could encourage future research and serve as a valuable source of information. Results/Conclusion: In terms of procedure efficiency, operator radiation reduction, and safety, the recent implementation and development of second-generation robotic systems have had a significant impact on interventional cardiology. This technology will play a significant role in the future of interventional cardiology as advancements eliminate the need for manual assistance, improve devices compatibility, and expand the use of robotics for telestenting procedures. A larger study demonstrating the safety and feasibility of tele-stenting over greater geographic distances, as well as addressing fundamental technical difficulties, would be required before attempting RePCI

ABSTRACT

Abstract Cardiovascular diseases are among important causes of death. Atherosclerosis is an important etiology for coronary artery diseases in which coronary artery calcification plays a principal role. Recently novel cardiovascular risk factors in coronary calcification are under attention. In this study, we investigated possible association between novel cardiovascular risk factors and coronary calcification. This is a prospectively registered systematic review and meta-analysis in PROSPERO and was performed in accordance with PRISMA guidelines. Medical databases were searched. Primary papers were screened and studies reporting our outcomes of interest were selected for data extraction. Quantitative data syntheses were performed using Comprehensive Meta-analysis Ver.3. In this study, 5252 papers were screened and finally 28 papers including 31241 patients underwent data extraction. Based on our findings, neutrophil/lymphocyte ratio (8 out of 10), red cell distribution width (r = 0.250, p < 0.0001), and interleukin 6 (odds ratio [OR]: 1.101 [95% confidence interval (CI): 1.001-1.210], p = 0.047) were associated with severity of coronary calcification while C-reactive protein (one out of eight) was not associated with coronary calcification. Results of lymphocyte/monocyte ratio (r = -0.120, p < 0.001), platelet/lymphocyte ratio (OR: 1.47 [95% CI: 0.89-2.41, p = 0.124]), and MPV (r = 0.017, p = 0.814 vs. OR: 1.91 [95% CI: 1.28-2.85, p = 0.002]) remained controversial due to few number of included studies or contrary results. We can conclude that neutrophil/lymphocyte ratio, red cell distribution width, and interleukin-6 are significantly associated with coronary calcification and C-reactive protein is not significantly associated with severity of coronary calcification. Our results about mean platelet volume, platelet/lymphocyte ratio, and lymphocyte/monocyte ratio are not reliable and require further investigations.


Resumen Las enfermedades cardiovasculares se encuentran entre las primeras causas de mortalidad. La aterosclerosis es una etiología importante de las enfermedades de las arterias coronarias en la que la calcificación de las arterias coronarias juega un papel principal. Recientemente, se están prestando atención a factores novedosos de riesgo cardiovascular en la calcificación coronaria. En este estudio investigamos la asociación posible entre los factores novedosos de riesgo cardiovascular y la calcificación coronaria. Esta es una revisión sistemática y metaanálisis registrados de forma prospectiva en PROSPERO y se realizó de acuerdo con las pautas de PRISMA. Se realizaron búsquedas en bases de datos médicas. Se examinaron los artículos primarios y se seleccionaron para la extracción de datos los estudios cuyos resultados fueron de nuestro interés. Las síntesis de datos cuantitativos se realizaron utilizando Comprehensive Meta-analysis Ver.3. En este estudio se seleccionaron 5252 artículos y finalmente se extrajeron los datos de 28 artículos que incluían 31241 pacientes. Según nuestros hallazgos, la proporción de neutrófilos/linfocitos (8 de 10), el ancho de distribución de glóbulos rojos (r = 0,250, valor de p < 0.0001) y la interleucina 6 (OR: 1.101 [IC del 95%: 1.001-1.210], valor p = 0.047) se asociaron con la gravedad de la calcificación coronaria, mientras que la proteína C reactiva (1 de 8) no se asoció con la calcificación coronaria. Resultados de la proporción linfocitos/monocitos (r = -0,120, valor p < 0,001), la proporción plaquetas/linfocitos (OR: 1,47 [IC 95%: 0.89-2.41, valor p = 0.124]) y el volumen plaquetario medio (r = 0.017, valor p = 0.814 C. OR: 1.91 [IC 95%: 1.28-2.85, valor p = 0.002]) siguieron siendo polémicos debido al escaso número de estudios incluidos o resultados contrarios. Podemos concluir que la proporción de neutrófilos/linfocitos, el ancho de distribución de los glóbulos rojos y la interleucina 6 se asocian significativamente con la calcificación coronaria y la proteína C reactiva no se asocia significativamente con la gravedad de la calcificación coronaria. Nuestros resultados sobre el volumen plaquetario medio, la proporción de plaquetas/linfocitos y la proporción de linfocitos/monocitos no son confiables y requieren más investigaciones.

ABSTRACT

Abstract Background: Coronary artery ectasia (CAE) is defined by focal enlargement of the coronary artery exceeding 1.5 times the adjacent normal segment. CAE can often cause arrhythmias, heart failure, sudden death, and myocardial ischemia. Ischemia due to microvascular dysfunction may be responsible for the ventricular heterogeneity in CAE. Objectives: The aim of our study was to evaluate the frontal QRS-T angle in patients with CAE. Methods: Our study included 55 patients with CAE and 50 individuals in the control group. Demographic characteristics and electrocardiographic parameters were compared between the two groups. Categorical variables were compared using the chi-square test. Continuous variables were compared using unpaired Student's t-test. P values < 0.05 were considered statistically significant. The frontal QRS-T angle was calculated from 12-lead electrocardiograms (ECGs) using the automatic report from the electrocardiography machine. Results: The average age of patients with CAE was 63.2 ± 3.4 years, with 18 women among them. The control group had an average age of 61.1 ± 3.2 years, with 28 women included. There was no significant difference in demographic parameters between the two groups. Compared to the control group, patients with CAE had significantly wider frontal QRS-T angle (p < 0.001), as well as longer QTmax duration, p = 0.002; Tp-Te interval, p = 0.02; and QT dispersion (QTd), p = 0.04. Conclusion: The frontal QRS-T angle can be calculated easily and time-efficiently using surface electrocardiography. In this study, we showed for the first time that the frontal QRS-T angle was significantly increased in patients with CAE.

ABSTRACT

Abstract Background: Ischemic heart disease is one of the most common causes of death worldwide. There are few data in the literature about the association of clinical profile and coronary angiography results in the Brazilian population. Objectives: To assess clinical variables and their associations with the results of coronary angiography and to evaluate the safety of coronary angiography in a public university hospital. Methods: From August 2015 to April 2018, 1 844 patients submitted to coronary angiography at the Pedro Ernesto University Hospital (HUPE, acronym in Portuguese) were enrolled in this cross-sectional study. They were evaluated by their clinical variables, angiographic results, and procedure complications. Logistic regression was used, and the criterion for determining significance was set at 5%. Results: The median age was 62 years, and most of the population (71%) were outpatients. Stable angina was the most common indication (62.9%). Only 19.7% underwent noninvasive cardiac testing. Arterial hypertension was the most prevalent (88.2%), followed by dyslipidemia (60.2%). Most patients (65%) had obstructive coronary artery disease (CAD). Left main coronary artery (LMCA) stenosis was found in 8.1% of patients. Older age, male sex, quantity of risk factors (RF), and peripheral artery disease were risk predictors for CAD. Death occurred only in 0.16% of the population, and acute coronary artery occlusion in 0.2%. Conclusion: Classic RF showed an association with CAD. The low incidence of complications suggests that coronary angiography is a safe procedure to be conducted in a public university hospital.

ABSTRACT

Abstract Background: Coronary artery disease (CAD) is the most common form of cardiac disease with high morbidity and mortality rates. Objectives: In this study, we evaluated the expression of miR-27a and miR-27b as biomarkers in peripheral blood mononuclear cells (PBMCs) of patients with CAD and investigated its correlation with cholesterol-efflux transporter, ATP-binding cassette transporter A1 (ABCA1). Method: This study was performed on 54 men with CAD and 51 healthy, sex- and age-matched control participants. The expression of miR-27a/b and ABCA1 genes in PBMCs were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The protein expression of ABCA1 was assessed by Western blotting. Concurrently, the specificity and sensitivity of miR-27a/b was evaluated through receiver operating characteristic (ROC) curve. The significance level adopted in the statistical analysis was 5%. Results: We found that miR-27a and miR-27b expression were significantly increased, while both mRNA and protein expression of ABCA1 were markedly reduced in the PBMCs of CAD patients in comparison to non-CAD controls. miR-27a/27b expression was also shown to be inversely correlated with ABCA1. ROC analysis showed that the miR-27a had an area under the ROC curve (AUC) of about 92.6 (sensitivity 83.3٪ and specificity 86.6٪) and miR-27b had an AUC of about 93.0 (sensitivity 86.6٪ and specificity 80.0 (%, suggesting the diagnostic potential of miR-27a/b in CAD patients. Conclusions: Our data suggested a possible role of miR-27a/b in CAD pathogenesis. Additionally, we proposed that miR-27a/b expression in PBMCs may have potential clinical implications in the diagnosis of CAD patients, but further validations in large cohorts are required.

ABSTRACT

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

ABSTRACT

Abstract Background: ST-segment elevation myocardial infarction (STEMI) is the acute coronary syndrome with the highest severity and mortality. It can affect physical health and well-being of patients, and consequently their quality of life (QoL). Objective: To describe the QoL of patients at 30 days and 180 days after STEMI, focusing on sex differences and repercussions on physical and mental dimensions. Methods: Observational study with 174 STEMI patients included in the study on STEMI conducted in the city of Salvador, Brazil (PERSISST). The QoL of patients at 30 days (D30) and 180 days (D180) after the coronary event was assessed using the 12-item short form health survey (SF-12). Physical and mental components of QoL were calculated using the SF-12 OrthoToolKit. Descriptive analysis of data was made using the IBM SPSS software, version 25.0. Results: Mean age of participants at D30 and D180 was 57.1±11.4 years and 60.5±10.9 years, respectively, with a higher prevalence of men (55.8% and 56.8%). In general, patients had a poor QoL at both time points (scores 49.1±8.9 and 49.9±8.4, respectively). Analysis by sex, however, showed that men had a good QoL at both 30D (score 51.8±7.4) and 180 D (score 51.3±7.7), whereas a poor QoL was found among women at these time points (45.7±9.6 and 48.1±9.0, respectively). Men showed higher physical and mental health scale scores than women at both D30 and D180, and there was a greater impairment of the physical component in both sexes. Conclusion: Patients had poor QoL at 30 days and 180 days after STEMI, with a greater impairment of the physical component and a worse QoL perception among women than men at both time points.

ABSTRACT

Abstract Background Patients with degenerated saphenous vein grafts (SVG) have a higher risk of developing no-reflow. The CHA2DS2-VASc score was established as a no-reflow predictor in patients with acute coronary syndrome (ACS). Objectives In our study, we aimed to assess the association between CHA2DS2-VASc score and no-reflow after the procedure and short-term mortality in patients with SVG who underwent elective percutaneous coronary intervention (PCI). Methods Our retrospective study comprised 118 patients who were divided into two groups according to the occurrence of the no-reflow phenomenon. The groups were compared on the basis of demographic characteristics, angiographic parameters, CHA2DS2-VASc scores, and outcome. A logistic regression analysis was additionally performed to determine the predictors of no-reflow. A p value of < 0.05 was considered statistically significant. Results Mean age of the participants was 66.4 ± 9.2 years, and 25.4% of them were female. Apart from the history of diabetes (p = 0.032), demographic data, blood parameters, ejection fraction, total stent length and diameter, medication use, median CHA2DS2-VASc score, and adverse cardiac events did not differ between the groups. In univariate logistic regression analysis, the presence of diabetes and stent length appeared to be associated with no-reflow, but not in multivariate analysis. The median CHA2DS2-VASc score was higher in non-survivors at 1-year follow-up (4.5 versus 3, p = 0.047). Conclusions In our study, we did not observe a significant relationship between no-reflow and CHA2DS2-VASc score. Larger studies are needed to reveal the indicators of improved post-intervention reperfusion in elective SVG PCI.

Introduction: Coronary bifurcation lesions are considered one of the challenging entities in the field of coronary intervention due to the risk of side branch loss and higher risk of stent thrombosis. However, there is limited data about the proper management of such lesions in the setting of myocardial infarction as most bifurcation lesion studies excluded patients with acute coronary syndromes (ACS). The aim of this study was to compare in-hospital and mid-term outcomes of single-stent and two-stents strategy in the management of bifurcation culprit lesions in patients presenting with anterior STEMI. Methods: This retrospective multi-center study included all patients presented with anterior STEMI who underwent primary PCI between January 2017 and December 2019, coronary angiography showed true bifurcation lesion with sizable side branch that can be managed by stenting. Patients with left main bifurcation, those indicated for urgent CABG, and patients in cardiogenic shock were excluded. Included patients were divided into two groups according to the stenting strategy either single or two stents. Six months follow up data were collected by telephone calls and by examination of medical records. Results: Out of 1355 anterior STEMI patients presented between January 2017 and December 2019, 158 patients (11.6%) were identified to have bifurcation culprit lesions with a sizable diagonal branch. 93 patients (59%) were treated by single stent while 65 patients (41%) were managed by two-stents strategy. The baseline characteristics and angiographic findings were similar in both groups except for higher side branch involvement in the two stents group (83.31%±11.20 vs 71.88%±15.05, t= -5.39, p <0.001). Mean fluoroscopy time (23.96±8.90 vs 17.81±5.72 mins) and contrast volume (259.23± 59.45 vs 232.58± 96.18 ml) were significantly higher in two stents group than single stent group (p=0.049). However, the angiographic success rates (residual stenosis ?30% and restoration of TIMI flow grade II or III) were comparable (96.8% vs 99%, MCp=0.151). There is no significant difference in the overall incidence rate of MACE in both groups 6 months following the index procedure (13.9 % vs 16.9%, FEp=0.698), with no difference between different bifurcation stenting techniques in patients managed with two stents. Conclusion: Although two stents strategy in the setting of STEMI is much complex with more fluoroscopy time and contrast volume, the procedural success rate and the incidence of MACE were comparable to one stent strategy, on medium-term follow up.

ABSTRACT

Non ST elevation myocardial infarction (NSTEMI) has been the subject of numerous studies. Risk stratification is a fundamental element for the management of NSTEMI; therefore, several scores have been established in this direction, particularly prognostic markers derived from the ECG. Aims: The aim of our study is to correlate the dispersion of the QRS with the severity of coronary lesions assessed by the GENSINI score in patients admitted for NSTEMI at the University Hospital of Marrakech. Methods: A retrospective study was conducted in the cardiology department of Mohammed VI university hospital of Marrakech from January 01, 2022 to March 31, 2022. Data was derived from the hospitalization register, including 30 patients (16 women and 14 men). Age ranged from 56 to 74 years with an average of 64.6 ± 9.3. Data was analyzed by SPSS, the level of significance set at p <0.05. Results: We found, in our study, a highly significant positive correlation between QRS dispersion (considered important if >20 ms) and admission heart rate (p=0.003) as well as the level of ultrasensitive troponins (p=0.003). There is also a very significant correlation between QRS dispersion and corrected QT interval (p=0.005), Moreover, we concluded that in patients admitted for NSTEMI, the greater the dispersion of the QRS, the higher the score of GENSINI (p<0.0001). Conclusion: The dispersion of the QRS is a simple marker on the ECG that can have a predictive value in different clinical contexts, particularly in acute ischemic heart disease. Further studies are needed, however, to validate its usefulness in routine practice.

ABSTRACT

Background: COVID-19 has appeared as a pandemic and public health issue at a universal level. First documented as a respiratory disease, COVID-19 has been found to interrelate with and disturb the cardiovascular system causing myocardial injury and also cardiac dysfunction. Initial documentation of cardiac pathology can play a substantial role in dropping the death rate. This study emphasizes on the relationship between the serum levels of cardiac Trop I and prognosis in patients with and without pre-existing CAD in COVID-19 patients. Aims and Objectives: The first objective was to explore the association among the serum levels of cardiac Trop I and bad prognosis in patients with antiquity of CAD and without CAD. The secondary objective was to explore and understand whether increased Trop I is an appreciated prognostic indicator for COVID-19 patient antagonistic prognosis. Materials and Methods: This was conducted as a retrospective observational study in which a whole of 45 patients admitted in COVID Hospital of Malabar Medical College and Research Center category C were studied. The medical record of the patients whose COVID-19 confirmation done by combined conclusions of reverse transcription PCR, symptoms, and chest X-ray was studies by the team. Results: Mean age of the study participants was 59.3 ± 13.7. Every study participants had elevated Trop I levels with a median Trop I in study subjects being 397.9. There was a statistically significant elevation in Trop I levels in patients with CAD linked with non-CAD patients with a median IQR of 641.6 and P = 0.003 and there was a significant increase in Trop I levels in patients who expired related to patients who got discharged with a median IQR of 587.3 and P = 0.003. Conclusion: From this study, we accomplish that rise in cardiac troponin-I level is connected with elevated mortality in patients with COVID-19. Hence, it can be used as significant biomarker of disease evolution, hospitalization, and worse prognosis in COVID-19 patients.

ABSTRACT

Background: Trinidad and Tobago ranks number 45 in the world for total deaths due to coronary heart disease. Predictive tests for coronary angiographic results set the basis for earlier monitoring of the disease before additional complications become obvious. Aims and Methods?This study aimed to evaluate the anthropometric and biochemical parameters of 124 patients with suspected coronary artery disease (CAD) in Trinidad and how these parameters correlate to the findings at angiography. Results?The biochemical parameters showed statistically significant correlations with CAD severity by Spearman's rank-order correlation. Two clinical parameters showed significant associations with CAD severity—ethnicity (?2 (4)?=?12.925, p?=?0.012) and presence of type 2 diabetes at baseline (?2 (4)?=?21.483, p?<?0.001). Conclusion?Biochemical parameters such as fasting blood sugar, N-terminal pro B-type natriuretic peptide, creatinine, and hemoglobin A1c were well correlated and well associated with the severity of CAD after diagnosis by the process of coronary angiography. Hence, these factors can be taken into consideration to predict the severity of CAD.

ABSTRACT

Background: Coronary artery disease (CAD) is characterized by atherosclerotic plaque accumulation in the epicardial arteries. The dynamic nature of the CAD process results in various clinical presentations. Red blood cell distribution width (RDW) is a practical, widely available marker for assessing the severity of coronary artery disease and helps in the risk stratification of patients with CAD. This study aimed to analyze the severity of CAD regarding the number of vessels involved. Material & Methods: This descriptive cross-sectional study included 124 purposively selected patients who underwent elective CAG in the Department of Cardiology, Chittagong Medical College Hospital, Chattogram, from January 2020 to June 2021. SPSS 23.0 software was used for processing and analysis at the end of the data collection period. Results: The age of the patients ranged from 32-75 years with a mean (±SD) age of 53.4 (±9.9) years. The majority of the patients (83.1%) were male with a male-to-female ratio of 4.9:1. On coronary angiography, the majority of the patients (51/124, 41.1%) had triple vessel disease, followed by double vessel disease in 23 (28.5%) patients, single-vessel disease in 31 (25.0%). In 19 (15.4%) patients no significant lesion was observed in any of the vessels. Gensini score ranged between 1 and 176 in the study with a median score of 56.77. The majority of the patients (69.4%) in the present study had a Gensini score ?30 indicating severe stenosis. A positive correlation between RDW and coronary artery disease severity in terms of Gensini score (r=0.393). With the increase of RDW, the Gensini score increases. It was found statistically significant (p=<0.001) by Pearson’s correlation test. There was a positive correlation between RDW and CAD severity regarding the number of vessels involved (rho =0.5). With the increase of RDW, the number of involved vessels increases. It was found statistically significant (p=<0.001) by Spearman’s correlation test. The Median (IQR) value of RDW was 13.5 (13.0-14.0) in patients with mild stenosis compared to 14.5 (13.9-15.0) in patients with severe stenosis. This difference was statistically significant (p<0.001). The median (IQR) value of RDW was the lowest in patients without any significant stenosis in any of the coronary arteries [13.1% (12.7%-13.5%)] and was the highest in patients with triple vessel diseases [14.5% (14.1%-15.0%)]. Conclusion: This study demonstrated that RDW level was an independent predictor for CAD and the severity of coronary stenosis. So, it can be concluded that RDW is an inexpensive routine laboratory test that might help identify high-risk patients before planning for a more invasive treatment strategy.

ABSTRACT

Introduction: Hypertension (HTN) is a modifiable risk factor for coronary artery disease, heart failure, cerebrovascular disease and chronic renal failure. HTN affects about 1 billion people globally; by 2025, up to 1.58 billion adults worldwide are likely to suffer from complications of HTN. This study was done to know the diet and physical activity patterns and HTN among the population of three districts of Western Rajasthan. Objectives: To study the dietary and physical activity patterns among the population of Western Rajasthan. and to compare key findings among three districts Pali, Jodhpur and Barmer so that lifestyle changes can be recommended. Methods: A case-control study was done among attendees of NCD clinics of tertiary-level centers in Pali, Barmer and Jodhpur. Hospital Controls were matched to age (± 5 years) and gender Considering the prevalence of HTN to be 20%*, the proportion of exposure in the general population as 0.2, odds ratio to be 2.2, power =80%, alpha=5% sample size is estimated to be 102 cases & 102 controls (from each district). Results: Overall being married (OR= 3.3), having diabetes Cardiac disease (OR= 2.6), excessive salt consumption (OR= 2.7), moderate physical exercise less than 30 minutes (OR=1.9), using oil other than vegetable oil(OR=1.8) , Age >?60 years (OR =1.4) were the key risk factors. It was found that high BMI (BMI>27), consumption of non-vegetable oils (12.7%) was highest in Jodhpur, lack of moderate exercise for at least 30 minutes (81%), lack of sports activity (92%) was highest in Pali, least number of days/week of fruits and vegetables consumption (~1.64 days) was seen in Barmer. Conclusions: Change in quantity of salt consumption and incorporation of moderate physical exercise for >30 minutes was most followed in control of HTN among the attendees of NCD Clinics from the multiple advise given.
