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...

background: stenting is currently the standard of care in percutaneous coronary intervention (pci). whether young patients remain at increased risk after pci in the present stent era has not been investigated widely. we evaluated angiographic characteristics and short- and mid-term outcomes in patients younger than 40 years of age who underwent pci. methods: from april 2003 to march 2005, prosp...

Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

objective(s):biochemical markers are important for the timely diagnosis and follow-up of ischemic events. most of the markers have been previously studied in the context of cardiac ischemia. however, research on markers of non-cardiac events has been insufficient. therefore, we investigated the relationship between troponin and myoglobin which are commonly used markers of cardiac ischemia, in n...

thrombotic thrombocytopenic purpura (ttp) is a rare syndrome affecting multiple organs. there is no sufficient evidence regarding the clinical cardiac manifestations of ttp. nonetheless, pathologic cardiac involvement is quite frequent in acute ttp, which is predominantly manifested as myocardial necrosis due to coronary arteriolar microthrombosis. the present case report describes a 43-year-ol...

background: given the importance of the role of depression in predicting the outcome of cardiovascular disorders, current medications for treating depression, particularly selective serotonin reuptake inhibitors (ssris), are taken into  consideration. this study aimed to systematically review the published findings in the use of ssris and the risk for cardiac events. materials and methods: an i...

background: this study sought to access differences in long-term (9 months) outcomes between acute coronary syndrome (acs) patients who undergo early intervention compared to percutaneous coronary intervention (pci) in stable and refractory conditions. methods: data originated from tehran heart center registry- interventional cardiology (thcr-ic) and consisted of 1267 patients divided into two ...
