Many patients undergoing pharmacological stress echocardiography for assessing symptoms suggestive of coronary artery disease are found to have a normal test. This study was performed to evaluate whether asthma symptoms simulate angina pectoris. A total 41 consecutive patients who had a negative pharmacological stress echocardiography and had been evaluated for angina pectoris were studied. Pat...

A 58 year-old Caucasian man was admitted to the coronary care unit with angina pectoris. There were deep inverted T waves and ST segment depression at anterior precordial derivations. Coronary angiography revealed widespread coronary artery to left ventricular microfistulae arising from distal portions of both left and right coronary systems. Left ventriculography and transthoracic echocardiogr...

OBJECTIVE EVIDENCES for angina pectoris, in the absence of proved myocardial infarction or grossly abnormal electrocardiograms, are more or less limited to abnormal electrocardiographic changes induced by exercise or hypoxemia. Similarly, while termination or prevention of angina is notoriously unreliable in the evaluation of "coronary dilator" drugs, their effects on provoked abnormalities in ...

BACKGROUND Intravenous iron and erythropoietin are commonly used for the treatment of anemia in end stage renal disease (ESRD) patients. Even though i.v. iron is proven to be very effective, there is great concern regarding its possible toxic effects. The aim of our study was to evaluate the possible correlation between iron administration and the incidence of angina pectoris in hemodialysis pa...

BACKGROUND Patients with chronic coronary artery disease exhibit a dysfunctioning endothelium, which may be responsible for exercise-induced platelet activation and expression of a procoagulant moiety. In this study, we evaluated the therapeutic efficacy of a low molecular weight heparin (Parnaparin) in patients with stable angina pectoris. METHODS AND RESULTS According to a double-blind, ran...

most of the patients imagine that chest pain is not sign of heart attack. but, may be pain is not sign of heart attack. pain source may be from pulmonary, stomach, intestinal, psychologic or musculoskeletal problems. from these factors, when two or more factors combine to each other, similar signs are happen. all of these factors harden diagnosis of chest pain reason. only with separation of pe...

BACKGROUND Due to overlapping symptoms and inadequate exercise capacity, noninvasive diagnosis of coronary artery disease (CAD) may be under- or overestimated in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE To assess outcomes of coronary angiography in COPD patients depending on baseline clinical characteristics. METHODS Medical records of 157 patients with COPD and...

Refractory angina, also described as chronic refractory angina pectoris (CRAP), classically occurs in patients with advanced, often diffuse coronary artery disease (CAD) that failed to be completely revascularized by percutaneous coronary intervention (PCI) and/or coronary artery bypass graft (CABG) with remaining angina pectoris symptoms despite maximized pharmacological intervention. In the m...

This is a case report of a 48-year-old female patient with a compatible history of Kawasaki disease during childhood, who was admitted to the emergency coronary unit with unstable angina pectoris. Coronary angiography identified two coronary aneurysms, one causing right coronary occlusion and the other causing severe obstruction of the left anterior descending coronary artery. Coronary artery b...

Coronary sinus blood flow was studied by the continuous thermodilution method in 13 subjects with normal coronary arteries and 14 patients with coronary artery disease during progressive elevation of the heart rate by atrial pacing. In 11 patients of the coronary group angina pectoris developed during pacing. In subjects with normal coronary arteries the coronary sinus blood flow rose proportio...
