We report a case of a 74-year-old male, who presented with an acute ST elevation posterior wall myocardial infarction (MI) 21 years following revascularization with three saphenous vein grafts (SVGs) to the left and right coronary arteries. In coronary angiography (CAG), the dilated SVG to the first marginal branch of the circumflex artery appeared only contrast enhanced in the proximal portion...

The objective of the present study is to investigate the relationship between the lesion characteristics of coronary artery and risk factors of coronary heart disease (CHD). A total of 430 patients underwent coronary angiography (CAG) were recruited from January 2008 to October 2009 and divided into CHD group (n=282) and non-CHD group (control group, n=148) according to the findings on CAG. The...

OBJECTIVE To examine whether we could predict myocardial ischemia when coronary artery calcification is detected by non-gated multidetector CT in patients with suspected ischemic heart disease. METHODS Eighty-three patients suspected of having ischemic heart disease (55 men, 28 women; age range 36-83 years; mean age 68 years) underwent multidetector CT and T1-201 single photon emission comput...

BACKGROUND The use of invasive procedures has mostly been studied in retrospective (multi)- national registries. Limited evidence exists on the association between microalbuminuria and coronary artery disease (CAD). METHODS The incidence of major adverse cardiac events (MACE) and invasive cardiac procedures was registered between 1997 and 2003 in 8139 subjects, without prior documented CAD, i...

Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

BACKGROUND Coronary artery calcification (CAC) measured by electron-beam computed tomography (EBCT) has been well studied in the prediction of coronary artery disease (CAD). We sought to evaluate the impact of the CAC score in the diagnostic process immediately after its introduction in a large tertiary referral centre. METHODS 598 patients with no history of CAD who underwent EBCT for evalua...

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...
