Background: Cystatin C (Cys C) as a cysteine protease inhibitor is produced in a constant level from all nucleated cells. The purpose of this study was to investigate the correlation between serum levels of Cys C and coronary slow flow (CSF) and body mass index (BMI) in men.
Methods: This investigation is in the form of a descriptive-analytical study. The statistical population was all non-active male aged 34-73 years with CSF candidate for angiography referring to Seyedoshohada University Hospital, Urmia, Iran, from March 2015 to February 2017. After obtaining an inform consent, 74 male patients (mean age 54.77±9.00 years, height 1.74±0.12 cm, weight 73.13±6.85 kg, and BMI 26.98±3.83 kg/m2) were selected by convenience non-random sampling as the sample size (patients were eligible for diagnostic coronary artery angiography for the first time and referring to Seyedoshohada University Hospital in Urmia). Then all the patients were placed under angiography with one mobile angiography system. Patients were assessed for coronary blood flow with a quantitative method using corrected thrombolysis frame count in myocardial infarction (CTFC). All the patients with TFC larger than two standard deviation pre-published area for a specific vessel were counted as CSF. Demographic characteristics of age, height, weight, and BMI in male patients were measured by wall-meter with an accuracy of one millimeter, digital scale with precision of 100 g, and weight/hieght2 formula, respectively. The traditional risk factors including smoking, diabetes mellitus (DM), high blood pressure (HBP), dyslipidemia, and family history were also assessed using a checklist. Serum levels of Cys C were measured by ELISA machine.
Results: The mean demographic and physiological variables of subjects were: age 54.77±9.00 yr, height 1.74±0.12 cm, weight 73.13±6.85 kg, and BMI 26.98±3.83 kg/m2. Also, the results of this study showed that there were no significant correlations between serum levels of Cys C with CSF and BMI in male patients’ candidate for angiography referring to Seyedoshohada University Hospital (P=0.871 and P=0.494, respectively).
Conclusion: The results of this study suggest that serum levels of Cys C had no significant correlations with the CSF and BMI in male patients’ candidate for angiography aged 34-73 years.

Background: Hypertension induces cardiac hypertrophy. Oxidative stress plays an important role in the pathogenesis of hypertension induced cardiac hypertrophy. Exercise and Quercetin (as activators of Sirtuins) reduce oxidative stress. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) with Quercetin supplement on oxidative stress and level of concentric pathologic hypertrophy in patients with hypertension and coronary heart disease after angioplasty.
Methods: The present study was conducted experimentally randomized, placebo-controlled and double‑blind on 24 men with hypertension and coronary heart disease after angioplasty aged 40-60 since years May to August 2019 at the Exercise Physiology department of Sport Sciences Faculty, Shahid Rajaee Teacher Training University, Tehran, Iran. The subjects were randomly divided into two groups of HIIT+quercetin (n=12) and HIIT+placebo (n=12) and were followed during 8 weeks of high-intensity interval training (30 seconds of activity and 30 seconds of rest) and quercetin consumption (250 mgr of quercetin supplement or placebo pills daily). Echocardiography was used to investigate morphological factors such as posterior wall dimension (PWd) and left ventricular end diastolic diameter (LVEDd). Plasma total antioxidant capacity (TAC) and malondialdehyde (MDA) were measured by colorimetric method.

Background: Coronary artery ectasia (CAE) is dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent normal coronary artery. The incidence of coronary artery ectasia is distinct in different countries that can be found in 1.2% to 5% of angiographic examinations.
Methods: This is a retrospective study that was conducted from September 2019 to February 2020 in Kermanshah University of Medical Sciences and the results were reported briefly. To obtain the desired articles, electronic searches were conducted in databases including the Scopus, PubMed, and Science Direct databases without time limited until October 2019. The keywords used were Coronary Artery Ectasia AND (Diabetes OR "Diabetes Mellitus"). This was done by two individuals separately and the final results were confirmed by a third person. Mixed method appraisal tool (MMAT) was used to evaluate the quality of studies. The structure of writing and the process of performing and reporting the study are based on the PRISMA checklist.
