To study myocardial perfusion, 201Tl myocardial scintigraphy was used to examine 25 patients with chronic alcoholism and alcoholic damage to the heart. 201Tl myocardial scintigraphy was performed at rest and repeatedly 3-7 days later by using the bicycle ergometer exercise test. The total 201Tl uptake at rest was 2.3 +/- 0.2%. The resting scintigrams of the patients showed a profound irregularity of 201Tl distribution and a diffuse decrease in its washout. The increment of 201Tl uptake in response to exercise was 20.6%. Exercise scintigrams displayed steady perfusion defects mainly of anteroseptal site. There was an improvement of tracer washout in the exercise test as compared at rest. Thus, 201Tl myocardial scintigraphy allows perfusion disturbances to be detected in patients with alcoholic damage to the heart. Myocardial scintigraphy performed at the peak of exercise records a decreased increment of 201Tl extraction, suggesting a lower perfusion reserve in patients with alcoholic heart damage. |
