Stress echocardiography for predicting cardiac events in octogenarians: is myocardial perfusion scintigraphy necessary anymore?

Department of Cardiology, Cleveland Clinic Florida, Fort Lauderdale 33309, USA.


The use of stress echocardiography (SE) in an elderly population was retrospectively evaluated and compared with myocardial perfusion scintigraphy (MPS) in a similar group. Patients > or = 80 years of age were evaluated by treadmill or pharmacologic SE (group 1; n = 65) to determine its predictive value for cardiac events. A second group had MPS (group 2; n = 68). We identified 11 patients in group 1 and 25 in group 2 who had a cardiac event, with no statistical significance between the positive predictive value of SE and MPS (55% vs 49%) and the negative predictive value of SE and MPS (89% vs 73%). The actuarial event-free survival was better for patients with negative SE than for patients with positive SE or negative or positive MPS. This study suggests that SE is comparable to MPS as a prognosticator of cardiac events in octogenarians. The retrospective design and the small population studied are major limitations. A larger, prospective trial should be launched to analyze this group and compare various stress tests.
