[Changes in segmental and general left ventricular myocardial contractility and intracardiac hemodynamics in the dipyridamole test of patients with ischemic heart disease (data of roentgenocontrast ventriculography)].
The dipyridamole test was performed during diagnostic coronaro-ventriculography in 7 patients showing no angiographic signs of coronary atherosclerosis (group 1) and 15 patients with a 75% stenosis in one or more coronary arteries (group 2). The test provoked an anginal attack in 11 (73%) second-group patients that was accompanied with the emergence or aggravation of asynergy in 10 (67%) or ischemic electrocardiographic changes in 7 (47%). In all cases, the anginal attack was associated with a rise in end diastolic pressure. All first-group patients showed no response to the dipyridamole test as evidenced clinically and electrocardiographically. No asynergic zones were identified on any of the ventriculograms recorded after dipyridamole administration.
