introduction: the precise time of using percutaneous coronary intervention (pci) after fibrinolytic therapy for maximum efficiency and minimum side effects is still undetermined. therefore, the present study was designed to compare the outcome of myocardial infarction (mi) patients who underwent surgical intervention (angiography and pci) within 48 hours of thrombolytic therapy or after that. m...

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. ...

coronary artery calcium scoring (cacs) is a reasonable test for patients with the possibility of atherosclerosis. it can also be used for reclassifying the coronary artery disease (cad) to the high-risk status by higher cacs and subsequently modifying the management of the patients.the purpose of this study was to investigate the association of cacs to the severity of coronary artery disease in...

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 ...

background: coronary computed tomography angiography (ccta) is a well-known method for evaluating anatomic coronary stenosis, but the reliability of ccta to predict cardiovascular events is an issue of controversy. materials and methods: in this prospective observational study, 58 patients with acute chest pain and low-to-moderate risk were selected and ccta was performed on them. during follow...

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 ...

background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, es­pecially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...

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...
