coronary heart disease (cad) is the leading cause of death specially among elderly. coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. myocardial perfusion scan is a noninvasive and sensitive method for evaluation of cad and is suggested by many investigators in recent years. in this study, 64 patients who had ...

the acute coronary syndrome due to the left main coronary artery (lmca) thrombosis is a clinically rare and catastrophic event.   we describe a young man ( smoker, alcoholic, and drug abuser) with a history of recent surgery and typical chest pain who had non-occlusive lmca thrombosis in coronary angiography. the thrombosis was successfully treated with two 180 µ/kg intracoronary boluses of ept...

Coronary aneurysms in adults are rare clinical entities. Herein, we presented a 54-year-old man who was admitted with an acute extensive anterior myocardial infarction. The emergency coronary angiography revealed an isolated large aneurysm at the proximal segment of the left anterior descending coronary artery. The patient was successfully treated with a graft-coated stent

Contrast-induced nephropathy (CIN) (known as contrast-induced acute kidney injury) occurs as a result of acute worsening of renal function following a procedure with administration of iodine contrasts agent and remains a substantial concern in clinical practices. The purpose of this study is to investigate the preventive effect of Pentoxifylline supplementation on reduction of CIN occurrence af...

BACKGROUND It is not known whether prehospital fibrinolysis, coupled with timely coronary angiography, provides a clinical outcome similar to that with primary percutaneous coronary intervention (PCI) early after acute ST-segment elevation myocardial infarction (STEMI). METHODS Among 1892 patients with STEMI who presented within 3 hours after symptom onset and who were unable to undergo prima...

BACKGROUND AND OBJECTIVES In the general population, an early invasive strategy of routine coronary angiography is superior to a conservative strategy of selective angiography in patients who are admitted with unstable angina or non-ST segment elevation myocardial infarction (MI), but the effectiveness of this strategy in individuals with chronic kidney disease (CKD) is uncertain. DESIGN, SET...

T he choice of a primary end point for evaluating the long-term results of percutaneous coronary interventions has come full circle since Andreas Gruentzig first evaluated the initial Zurich experience.' At that time, he equated the long-term success of percutaneous transluminal coronary angioplasty (PTCA) (predominantly in patients with single-vessel disease) to ongoing freedom from a composit...

AIMS Women with chest pain but without obstructive coronary artery disease (CAD) are considered at low risk for cardiovascular (CV) events, but half continue to experience debilitating chest pain over many years. This study compared CV outcomes in women with persistent chest pain (PChP) vs. those without PChP. METHODS AND RESULTS We studied 673 Women's Ischaemia Syndrome Evaluation (WISE) par...
