Two exercise tests, one under basal conditions and one after sublingual nitroglycerin (NTG), were performed in 39 patients with stable angina pectoris--16 with critical coronary stenoses and 23 with normal coronary arteries (syndrome X). Under basal conditions, times at ischemic threshold, at peak exercise, and at complete ECG recovery were similar in the(More)
In a series of patients with TIA or minor stroke we have investigated the possibility of a different distribution of risk factors according to the presence or absence of angiographic lesions of the cerebral arterial circulation. The differences observed, though not statistically significant, argue for a more severe and widespread atherosclerotic process in(More)
In 50 patients with stable effort angina the effect of three drugs, metoprolol, nifedipine, and diltiazem was assessed by analyzing exercise stress test response and ambulatory ECG recordings. Both metoprolol and diltiazem caused a significant increase in time to ischemic threshold during exercise and a significant decrease of maximum ST-segment depression(More)
To investigate the effects of the acute administration of aminophylline and nitroglycerin on effort ischemia, 20 patients with syndrome X underwent 3 bicycle exercise tests after sublingual nitroglycerin (0.3 mg) and after 90 minutes of oral administration of aminophylline (400 mg). Compared with the basal test, only aminophylline induced a significant(More)
Au-195m is a radio-isotope with an ultra-short half-life with which multiple sequential evaluations of ventricular function can be made. In order to evaluate the reliability and reproducibility of analyses of overall and regional ventricular function by radio-isotope ventriculography with Au-195m we studied 10 healthy volunteers and 12 patients with(More)
