AIMS Patients with acute coronary occlusion may lack typical signs of myocardial infarction in the electrocardiogram. We tested the ability of different echocardiographic modalities to identify coronary occlusion by quantifying myocardial dysfunction in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS AND RESULTS One hundred and fifty patients were examined by echoca...

OBJECTIVES The purpose of this study was to investigate the correspondence between the coronary arterial anatomy and supplied myocardium based on the proposed American Heart Association 17-segment model. BACKGROUND Standardized assignment of coronary arteries to specific myocardial segments is currently based on empirical assumptions. METHODS A cardiac magnetic resonance study was performed...

The effects of an intracoronary aminophylline infusion, adjusted to give a constant concentration of 25 microgram.cm-3 coronary blood, on the reactive hyperaemic responses following coronary occlusion for 4, 10, and 25 heart beats were investigated in anaesthetised, open-chest dogs. The vasodilator effect of intracoronarily-administered adenosine and the hyperaemic response after coronary occlu...

Previous reports have described an inverse relationship between alcohol consumption and the prevalence of myocardial infarction or the extent of coronary artery occlusion. The study reported here explored the relationship between patterns of alcohol intake and coronary occlusion in 526 patients who have had coronary arteriography. Patients were characterized as regular drinkers, occasional drin...

BACKGROUND The purpose of this investigation was to compare the magnitude of change in myocardial perfusion and function during exercise with that obtained during total coronary artery occlusion. Radionuclide studies are widely used for the diagnosis and determination of prognosis in patients with suspected or known coronary artery disease. These studies are based on the premise that the relati...

Ischemic heart disease presents with various symptoms, and chest pain is a chief complaint. Occlusion of the left main trunk often results in serious symptoms such as cardiogenic shock. However, while extremely rare, left main trunk occlusion can present with only slight chronic symptoms. In the present case, a 62-year-old woman with few risk factors for ischemic heart disease visited our hospi...
