Objective: Epicardial fat is an indirect contact with coronary arteries. There are some studies about the relationship between this fat and metabolic syndrome and it has considered as an indicator of cardiovascular risk. Several studies have addressed the association between epicardial fat thickness (EFT) and coronary artery disease (CAD) with conflicting results. The aim of our study was to evaluate the hypothesis that echocardiographic EFT thickness could be a marker severe CAD. Methods: Overall, 315 cases who underwent coronary angiography were classified in two groups: Normal and CAD. Measurement of EFT was done with echocardiography. The difference between mean EFT in two groups was analyzed. Califf scoring considered for severity of CAD. Then the relationship between EFT and age, sex, body mass index (BMI), serum lipids and severity of CAD was evaluated. The obtained data were compared by using ANCOVA test, Pearson and Spearman's partial correlation analyses. Results: The EFT in CAD group was significantly higher than in normal group (5.4±1.9 mm vs 4.4±1.8mm, p=0.0001). EFT had a positive relationship with Califf scoring of diseased coronary arteries (r=0.158 p=0.04), low-density lipoprotein cholesterol (p=0.04), female gender (p=0.02), BMI (p=0.001) and serum triglyceride levels (p=0.04).

OBJECTIVE:To investigate the relation between major depressive disorder and metabolic risk factors of coronary heart disease.INTRODUCTION:Little evidence is available indicating a relationship between major depressive disorder and metabolic risk factors of coronary heart disease such as lipoprotein and apolipoprotein.METHODS:This case–control study included 153 patients with major depressive disorder who fulfilled the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM‐IV), and 147 healthy individuals. All participants completed a demographic questionnaire and Hamilton rating scale for depression. Anthropometric characteristics were recorded. Blood samples were taken and total cholesterol, high‐ and low‐density lipoproteins and apolipoproteins A and B were measured. To analyze the data, t‐test, χ2 test, Pearson correlation test and linear regression were applied.RESULTS:Depression was a negative predictor of apolipoprotein A (β = −0.328, p<0.01) and positive predictor of apolipoprotein B (β = 0.290, p<0.05). Apolipoprotein A was inversely predicted by total cholesterol (β = −0.269, p<0.05) and positively predicted by high‐density lipoprotein (β = 0.401, p<0.01). Also, low‐density lipoprotein was a predictor of apolipoprotein B (β = 0.340, p<0.01). The severity of depression was correlated with the increment in serum apolipoprotein B levels and the decrement in serum apolipoprotein A level.CONCLUSION:In view of the relationship between apolipoproteins A and B and depression, it would seem that screening of these metabolic risk factors besides psychological interventions is necessary in depressed patients.

Background:Appearance of microalbuminuria, particularly in patients with hypertension, might be associated with a higher prevalence of left ventricular (LV) dysfunction and geometric abnormalities. This study was undertaken to determine whether high urine albumin to creatinine ratio (UACR) as a sensitive marker for microalbuminuria can be associated with LV hypertrophy (LVH) and systolic and diastolic LV dysfunction.Methods:The study population consisted of 125 consecutive patients with essential uncomplicated hypertension. Urine albumin and creatinine concentration was determined by standard methods. LVH was defined as a LV mass index >100 g/m2 of body surface area in women and >130 g/m2 in men. Echocardiographic LV systolic and diastolic parameters were measured.Results:The prevalence of microalbuminuria in patients with essential hypertension was 5.6 %. UACR was significantly no different in patients with LVH than in patients with normal LV geometry (21.26 ± 31.55 versus 17.80 ± 24.52 mg/mmol). No significant correlation was found between UACR measurement and systolic and diastolic function parameters, including early to late diastolic peak velocity (E/A) ratio (R=-0.192, p=0.038), early diastolic peak velocity to early mitral annulus velocity (E/E') ratio (R=-0.025, p=0.794), LV ejection fraction (R=0.008, p=0.929), and LV mass (R=-0.132, p=0.154). According to the receiver operator characteristic (ROC) curve analysis, UACR measurement was not an acceptable indicator of LVH with areas under the ROC curves 0.514 (95 % confidence interval 0.394–0.634). The optimal cut-off value for UACR for predicting LVH was identified at 9.4, yielding a sensitivity of 51.6 % and a specificity of 48.3 %.Conclusion:In patients with uncomplicated essential hypertension, abnormal systolic and diastolic LV function and geometry cannot be effectively predicted by the appearance of microalbuminuria.

Background:Recently, the relationship between increased level of inflammatory mediators and occurrence of left ventricular failure in patients with kidney disease has been suggested. The present study attempted to assess relationship between inflammatory mediators and occurrence of left ventricular failure in patients with chronic kidney disease.Materials and Methods:This cross-sectional study was performed at Noor and Hazrat Aliasghar hospital in Isfahan between September 2012 to September 2013 on patients aged >19 years that referred for following their chronic kidney disease. Serum level of inflammatory parameters including C-reactive protein (CRP) and Interleukin-6 (IL-6) was measured using spectrophotometer. All patients were also assessed using M-mode echocardiography to determine left ventricular ejection fraction (LVEF).Results:The group with significant reduced LVEF showed lower GFR when compared to the normal LVEF group (40.73 ± 20.61% versus 44.43 ± 17.98%, P = 0.032). Comparing GFR across the three groups with normal LVEF (>55%), with mild LV dysfunction (LVEF: 45 – 55) those with significant LV dysfunction (LVEF < 45%) showed significantly lower GFR level in latter group compared with normal LVEF and mild LV dysfunction group (P = 0.026). Although the level of serum CRP was significantly higher in patients with significant left ventricular failure than other groups (P = 0.018).Conclusion:Inflammatory processes can potentially affect left ventricular function in patients with chronic kidney disease. In this regard, increased level of CRP may be a main factor for predicting severity of left ventricular failure in these patients.

Background: The relation between left anterior descending artery (LAD) anatomy and clinical outcomes in patients with anterior ST-segment elevation myocardial infarction (STEMI) has not been fully investigated. The aim of this study was to determine the frequency and severity of short-term cardiovascular outcomes in patients with Anterior ST-Segment Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous intervention (PCI), based on wraparound and non-wraparound left anterior descending artery (LAD). Methods: In a cross-sectional study, 126 patients with anterior STEMI who were admitted to Shahid Chamran Hospital in Isfahan during 2020 were studied. Patients were evaluated for anatomical features of LAD coronary artery and clinical outcomes determined and compared based on wraparound LAD and non-wraparound LAD during hospitalization and up to one month after PCI. Results: The prevalence of wraparound LAD in the studied patients was 73% and left ventricular systolic dysfunction in admission was greater and more severe in patients with wraparound LADs compared with those with non-wraparound. Severe LV systolic dysfunction in the wraparound and non-wraparound groups was 39.6% and 8.8%, respectively ( P < 0.001). Also, the frequency of arrhythmias in the wraparound group (21.7%) was higher than the non-wraparound group (5.9%) ( P = 0.037). Conclusion: The patients with anterior STEMI and wraparound LAD have a worse clinical outcome and more severe left ventricular systolic dysfunction. Therefore, it seems that the study of the anatomical condition of the LAD artery at the time of angiography is of great importance in the way of observation and care, and treatment of patients.
