introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

anxiety may negatively affect the course of coronary artery disease (cad). the aim of this study was to assess which factors are associated with anxiety in young adults with cad. a cohort of individuals with premature coronary artery disease was formed between 2004-2011, as the tehran heart center's premature coronary atherosclerosis cohort (thc-pac) study. patients (men≤45-year-old, and women≤...

introduction: hot flashes (hf) and night sweats (ns) are due to vasomotor instability and could be recognized as cardiovascular risk markers. therefore, this study aimed to evaluate the relationship between vasomotor instability and severity of coronary artery disease (cad) in postmenopausal women.  materials and methods: this observational cross sectional study, was performed in chamran hospit...

conclusions according to the results of the study, abdominal obesity is as a risk factor for atherosclerosis. therefore, the use of a simple, low cost and high precision method for determining visceral obesity and preventing the cad is warranted. background despite efforts made by the medical community and public health officials for combating 76 obesity, the prevalence of overweight and obesit...

Many epidemiological studies have reported an association between hemostatic factors and risk of both coronary and peripheral artery diseases. Using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis, we investigated the association between coronary artery disease and polymorphisms in the methylenetetrahydrofolate reductase (MTHFR C677T and A1298C), proth...

endothelial dysfunction and carotid intima-media thickness are 2 indicators of subclinical cardiovascular disease. the aim of study was to analyze brachial flow mediated dilation(fmd)and carotid intima media thickness (cimt)in patients with coronary artery disease, and investigate the relationship between endothelial function, cimt and coronary artery disease risk factors.56 men and women aged ...

conclusions a significant proportion of coronary atherosclerotic plaques in cadavers with confirmed acute myocardial infarction were detected to be infected with cytomegaloviruses while no infections of c. pneumoniae and h. pylori were detected. patients and methods sixty cadavers in two equal groups were analyzed. acute myocardial infarction group included cadavers with acute myocardial infarc...

background: given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (abi) as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test. methods: this case-control study, conducted between 2010 and 2011 in tehran heart center, recruited 362 angiographi...

more than eighty percent of patients with coronary heart diseases (chd) have conventional risk factors. prevalence of well known risk factors seems to show a different pattern in younger patients and individual above 55 years. to evaluate the pattern of conventional chd risk factors in healthy individuals in two different age groups. a large scale population based survey of 31999 individuals fr...
