Abstract

Recently, we have shown the usefulness of high-dose dipyridamole echocardiography testing (DET) as an exercise-independent method for the evaluation of patients having coronary angioplasty. The purpose of the present study was to determine the value of DET compared with exercise testing in the early functional evaluation after successful percutaneous transluminal coronary angioplasty (PTCA) and in the prediction of late recurrence of angina. We performed DET and exercise testing in 52 consecutive patients both before and after successful PTCA. Criteria of positivity for DET were transient dyssynergy absent or negligible in the baseline examination and exercise testing for an ST segment shift >0.1 mV from baseline. All patients had an angiographically successful PTCA: the percent stenosis went from 78±7% before to 30±7% after PTCA. Exercise testing was positive in 49 and 29 patients, respectively, before and after PTCA (94% versus 44%, p50% lumen reduction). We conclude that variations in DET both before and after PTCA are better correlated to the anatomic results of the procedure than variations in exercise testing. With regard to the early identification of a subset at higher risk for recurrence of angina after PTCA, a negative exercise test has a higher negative predictive value than DET, whereas the latter has a higher positive predictive value.
