In comparison to the myocardial perfusion scintigraphy, a treadmill stress test is a viable, efficient and cost effective option to predict cardiovascular events in elderly patients

To define the prognostic value and cost-effectiveness of the treadmill stress test (TST) in comparison to the dipyridamole myocardial perfusion scintigraphy (DIP), in individuals > or = 75 years of age. Consecutive and prospective assessment of 66 patients (40% male) aged 81 +/- 5 years of which...

Description
Summary:To define the prognostic value and cost-effectiveness of the treadmill stress test (TST) in comparison to the dipyridamole myocardial perfusion scintigraphy (DIP), in individuals > or = 75 years of age. Consecutive and prospective assessment of 66 patients (40% male) aged 81 +/- 5 years of which 57% were hypertensive, 38% had dyslipidemia and 28% were diabetics. The Bruce protocol was adapted for a tilt treadmill and the TST prognostic value was obtained using the Duke treadmill score. The TST duration, recommended maximum heart rate percentage and double product at peak exercise were respectively: 7 +/- 3 minutes, 95 +/- 9% and 24,946 +/- 4,576 (bpm x mmHg). The TST and DIP presented similar positive results for myocardial ischemia (21% vs 15%, respectively). The correlation between the tests was 88% (Kappa 0.63, p
