Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

this study evaluated the relationship between the location of the most severe coronary artery stenosis and the subsequent acute myocardial infarction (ami). methods: of 1590 patients who were admitted with a diagnosis of ami, we identified 44 patients who had undergone previous myocardial perfusion spect. thirty-one of these patients also had previous coronary angiography. the relationship betw...

large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...

 Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery.  Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...

  Abstract   Background: Recently, small dense low density lipoprotein (sdLDL) has been   highlighted as a new risk factor for the coronary artery disease (CAD).Small dense   LDLs are believed to be atherogenic since these particles are taken up more easily by   arterial wall. They are readily oxidized and have reduced affinity for low density   lipoprotein (LDL) receptor and increased affinity...

impaired fasting glucose identifies individuals at high risk of progression to diabetes but the role of ifg as a coronary artery disease risk factor, independent of its progression to diabetes and its association with other coronary artery disease risk factors ,is unclear. a cross-sectional study was conducted to evaluate the hypothesis that impaired fasting glucose increased the likelihood of ...

Purpose: To assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in Cardiac Magnetic Resonance of patients with history of remote myocardial infarction. Materials and Methods: The Cardiac Magnetic Resonance images of sixty patients with history of remote ST segment or non-ST segment elevation myocardial infarction were ...
