- W2415334671 abstract "To value stress tolerance and stress myocardial perfusion before and after a week of oral therapy with gallopamil 150 mg daily, we studied 10 patients suffering from stable effort angina. We performed bicycle exercise stress testing and thallium scintigraphy (Tl) with planar technique in 3 projections (anterior-posterior and oblique left anterior at 45 and 70 degrees) according to the current standards. We valued systolic and diastolic blood pressure (SBP-DBP), heart rate (HR) and HR-SBP product at rest, at symptoms stress-induced and at the end of the procedure. Moreover we valued work threshold of chest discomfort and ischemia, the maximal work capacity and the perfusion defects according to a Tl score obtained dividing the 3 projections in 5 segments and fixing a value according to the observed perfusion from 0 = normal perfusion to 3 absent perfusion. We observed a significant reduction of basal HR (77 vs 71, p = 0.05), SBP (147 +/- 15 vs 131 +/- 15 mmHg, p = 0.001), DBP (91 +/- 6 vs 83 +/- 6 mmHg, p = 0.002). Work threshold of chest discomfort and ischemia significantly arose (8 +/- 3 vs 11 +/- 4 min., p = 0.002; 6 +/- 3 vs 10 +/- 4 min., p = 0.001). The HR-SBP product at the maximal work capacity and the Tl score significant decreased (31650 +/- 6239 vs 29406 +/- 5418, p = 0.003; 8 +/- 2 vs 5 +/- 1, p = 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
