Background: Rose questionnaire is a standard mean for diagnosing angina pectoris in epidemiological study. The present study was done to determine the prevalence of angina pectoris according to Rose questionnaire for chest pain, and to investigate the association of angina with several coronary hearh disease risk factors in Tehran urban population (district-13) during 1999 to 2000. Methods: 60...

Background. In patients with stable angina pectoris aminophylline, a nonselective antagonist of adenosine receptors, markedly improves exercise capacity. To establish the role played by A, adenosine receptors in the anti-ischemic action of aminophylline, the effects of bamiphylline, a selective A, antagonist, on exercise-induced ischemia were investigated in patients with stable angina pectoris...

BACKGROUND Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associat...

Background—We previously reported that 20% of women with chest pain but without obstructive coronary artery disease (CAD) had stress-induced reduction in myocardial phosphocreatine–adenosine triphosphate ratio by phosphorus-31 nuclear magnetic resonance spectroscopy (abnormal MRS), consistent with myocardial ischemia. The prognostic implications of these findings are unknown. Methods and Result...

Syndrome Xdefines a group of patients who present with typical, usually exertional angina pectoris and a normal coronary arteriogram. They often have a positive exercise test, but direct signs of ischemia are detectable in only a minority of patients. Areduced coronary vasodilative response to dipyridamole or pacing is observed in such patients with or without a positive electrocardiographic ex...

Acute coronary syndromes are a major public health problem and the leading cause of death in the western world. Acute coronary syndromes consist of unstable angina pectoris, non-ST-segment-elevation myocardial infarction, and ST-segment-elevation myocardial infarction. These diseases represent a continuum of increasing severity and are pathophysiologically linked to intracoronary thrombus forma...

FIGURE 1 Snapshot Showing Bridging in the Mid-Left Anterior Descending Artery Before Adenosine Infusion W e report the case of a fit 90-year-old woman presenting with increasing episodes of angina. Diagnostic angiography identified a mid-left anterior descending artery myocardial bridge (MB) (Figure 1, Online Video 1) as well as a moderate diagonal disease. We performed fractional flow reserve ...

BACKGROUND Transmyocardial laser revascularization (TMLR) is an alternative treatment modality for patients with refractory angina who are not candidates for conventional surgical or percutaneous revascularization. Clinical studies of TMLR have not shown one-to-one correlation between increased myocardial perfusion and improved clinical status. METHODS Three patients (51, 53, and 70 years old...
