BACKGROUND Dipyridamole and dobutamine stress echocardiography testing are most widely utilized, but their sensitivity remained suboptimal in comparison to routine exercise stress echocardiography. The aim of our study is to compare, head-to-head, exercise, dobutamine and dipyridamole stress echocardiography tests, performed with state-of-the-art protocols in a large scale prospective group of ...

Recently, Feng et al. (1) published an article entitled “Altered heart rate variability depends on the characteristics of coronary lesions instable angina pectoris” in Anatol J Cardiol, where they have shown that the parameters of heart rate variability (HRV) are associated with the severity of coronary lesions in patients with stable angina pectoris. Noninvasive detecting the severity of coron...

The effects of indoramin, a selective alpha 1 adrenoceptor antagonist, on exercise tolerance were studied in 15 patients using a random double blind crossover protocol. All patients had chronic stable angina, for which 13 had been receiving beta adrenoceptor blocking drugs and nitrates, and these were continued unchanged throughout the study. An initial open challenge with indoramin in eight pa...

Sixteen patients with documented angina pectoris were exercised on a bicycle ergometer to an end point of moderately severe angina pectoris. Electrocardiograms and blood pressure were taken at one-minute intervals. The reliability of the testing procedure was gauged from the reproducibility of the values of both maximum ST segment depression and maximum double product at the end point of the te...

OBJECTIVES This study analyzes the long-term course of patients with typical angina pectoris or anginalike chest pain and normal coronary angiographic findings. BACKGROUND In previous studies of such patients the rate of occurrence of typical coronary events during follow-up has differed widely, depending on the duration of the study and the number of patients. METHODS One hundred seventy-s...

Myocardial scintigraphy with thallium-201 and electrocardiogram-gated left ventriculography with technetium-99m labelled red blood cells were applied in four groups of subjects: 25 with no signs or symptoms of cardiovascular disease (group 1), 28 with a "false" positive exercise electrocardiogram (group 2), 14 with angina pectoris and normal coronary angiograms (group 3), and 43 with angina pec...

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...

Forty-six men under age 70, without clinical congestive heart failure or unstable angina pectoris, performed treadmill tests 3, 5, 7, 9 and 11 weeks after myocardial infarction. Patients were more frequently able to perform moderate exertion (2 mph, 14% grade) at 7 and 11 weeks than at 3 weeks following infarction. Ischemic ST-segment depression, usually unaccompained by angina pectoris, occurr...

Eight patients with a diagnosis of atherosclerotic heart disease and a history of typical angina pectoris, uncomplicated by cardiac dilatation or heart failure, were studied by means of standardized, symptom-limited treadmill exercise test. Repeatability of such testing was determined during two control tests 1-1.5 hours apart. From two to six days later, the same patients performed two treadmi...
