Although many patients with coronary artery disease (CAD) have a positive exercise test without pain, the frequency and significance of this "silent" ischemia is unclear. Therefore, we studied 122 consecutive clinically stable patients with angiographically defined CAD (greater than 75 per cent luminal stenosis) and a positive exercise test. Seventy-eight ...

The effects of nitroglycerin (TNG) on exercise-induced abnormalities of left ventricular wall motion and ejection fraction are unknown in symptomatic and asymptomatic patients with coronary artery disease (CAD). In the present investigation radionuclide cineangiographic studies were performed in 47 patients with CAD (14 without angina during exercise) and in 25 ...

In order to improve the value of exercise tests for the detection of coronary artery disease (CAD) a system for on-line computer processing of the Frank lead exercise ECG was developed. Data were analyzed from 95 patients with CAD and 129 ostensibly healthy men. All subjects had a normal ECG ...

Near-maximal isometric exercise (IHG) was employed to provoke new, or alter pre-existing fourth heart sounds (S4s) in ambulatory middle-aged normal subjects (N), hypertensive patients (HHD), and patients with coronary disease (CAD). S4 amplitudes and systolic time intervals (STIs) were measured blindly. No subjects without a resting S4 developed a new ...

The submaximal treadmill exercise test is a valuable noninvasive tool for the diagnosis of overt or latent coronary artery disease (CAD). When submaximal heart rates of 80% to 90% of the predicted maximal rates are attained and when ST-segment depression of at least 1 mm is taken as a criterion ...

In summary, near-maximal or maximal exercise testing has a sensitivity of approximately 60% and a specificity of approximately 90% for coronary atherosclerotic heart disease. When screening asympatomatic men with exercise testing, an abnormal response identifies a group of men at very high risk for coronary artery disease. However, the predictive ...

The sensitivity of myocardial perfusion imaging (MPI) using thallium-201 injected both at rest and during peak exercise was compared to simultaneously recorded 12 lead electrocardiography (ECG) for the detection of transient ischemia in 20 normal subjects and 63 patients with coronary artery disease (CAD). No significant perfusion defects or ECG ...

The relationship between regional myocardial blood flow and the results of exercise tests were evaluated in 54 patients, 40 of whom had angiographically demonstrated coronary artery disease (CAD) and 14 had normal angiograms. After 20 patients had 2-step tests, 20 had bicycle ergometry, and 14 had treadmill tests, regional myocardial ...

Brief-tone audiometry was administered to two groups of listeners. The first group consisted of five sophisticated subjects with normal hearing, who were tested under normal and simulated hearing-loss conditions. The second group consisted of five patients with true pseudohypacusis. Results under simulated and true pseudohypacusic conditions were similar, but were ...

Twenty-eight patients with hypertensive cardiovascular disease (HCD) and incipient myocardial dysfunction underwent hemodynamic studies at rest and during exercise before and 30 minutes after administration of 0.6 mg beta-methyl-digoxin intravenously. Measurements were made during right heart catheterization with a balloon-tipped catheter. The hemodynamic changes after administration of digitalis did not ...

This study has assessed whether chest pain occurring during or after a step test could improve the accuracy of exercise testing in the diagnosis of coronary artery disease (CAD). One hundred and fifty-three consecutive men underwent the double Master two-step test prior to diagnostic coronary arteriography. On hundred and twenty-five ...

The concentration of lysozyme (LZM) in cerebrospinal fluid (CSF) has been studied in 148 patients to evaluate its possible significance in the differential diagnosis of various diseases affecting the central nervous system (CNS). In the control group only 3 of 45 patients had detectable LZM in their CSF, the highest ...

In 24 patients with a pheochromocytoma, angiography revealed a multiple localization in 20%, extra-adrenal localization in 20%, and insufficient information supplied by aortography in 25%. On the basis of this experience, several proposals are advanced for optimal execution of the vascular study, including retrograde phlebography of apparently normal adrenal glands ...

Background: Recovery indices of oxygen-consumption (VO2) kinetics have been observed as an important factor to evaluate and differentiate patients (pts) with various degrees of chronic heart failure (CHF) and less for pts with coronary artery disease (CAD). Objectives: To find the significance of recovery-VO2 kinetics indices in differentiating pts with ...

Accurate and safe diagnostic testing provides the crucial link between detection and optimal management of coronary artery disease (CAD). Noninvasive diagnostic testing for CAD may be less accurate in women than in men. Many noninvasive diagnostic modalities are available for this purpose. An exercise tolerance test provides an assessment of ...
