background: investigators frequently encounter continuous outcomes with plenty of values clumped at zero called semi-continuous outcomes. the gensini score, one of the most widely used scoring systems for expressing coronary angiographic results, is of this type. the aim of this study was to apply two statistical approaches based on the categorization and original scale of the gensini score to ...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

conclusions the eft, as measured by echocardiography, with a cut off value 2.95 mm has a strong association with premature cad. results among baseline characteristics, waist circumference, triglyceride levels, cigarette smoking and history of statin use were significantly higher in the cad group. the body mass index (bmi) was significantly higher in the non-cad group. according to echocardiogra...

background: the existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (cad). however, the results of the studies conducted hitherto on this subject are inconsistent. we sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of cad in patients undergoing n...

background and objective: obstructive sleep apnea (osa) is frequent and in some degree it affects about 24% of male and 9% of female in middle age adults. this study aimed to assess the association between risk of osa and cad. materials and methods : this case-control study was performed among 184 patients with a history of coro- nary angiography in two catheter labs at hospitals in qom, iran. ...

background: coronary angiography, albeit a safe procedure, may cause serious complications especially in patients with left main stenosis (lms). this study was designed to investigate the efficacy of workload achieved by exercise tolerance test (ett) in predicting lms in candidates for coronary angiography. methods: a total of 743 patients with a positive ett who subsequently underwent cardiac ...

conclusions the pattern and number of vessels involved were similar in both groups. based on common prevalence of traditional risk factors among two groups, planning for lifestyle changes is recommended. results of the 112 patients, 51 (45.5%) were in group a and 61 (54.5%) were in group b with mean age of 37.6 ± 4.4 and 63 ± 8.5, respectively. no significant statistical differences were found ...

conclusions the scf phenomenon is relatively frequent, particularly among patients with acute coronary syndrome who are scheduled for coronary angiography. hypertension, a low hdl-c level, and high hemoglobin level can be considered independent predictors of this phenomenon. results among the 3600 patients scheduled for selective coronary angiography, 75 (2%) met the scf criteria. scf and neca ...

conclusions our findings revealed that the severity of coronary artery stenosis is common in diabetic patients compared to nondiabetics. early diagnosis and treatment of cad in diabetic patients is recommended. results based on data found in our study, 93.8% of diabetic and 83.4% of nondiabetic patients were shown to suffer coronary artery stenosis. severe involvement (grade 3vd) of coronary ar...
