The aim of this study was to determine the value of treadmill test for detecting restenosis after percutaneous transluminal coronary angioplasty. The study material was consisted of 32 patients (31 males and 1 female; the mean age was 20.2 9.6 years, range 30-68 years) with single-vessel or multivessel coronary heart disease. Complete revascularization was achieved in 42 lesions of all patients. Submaximal exercise treadmill test was performed 15th, 30th, 90th and 180th days after coronary angioplasty; and if was found to be positive coronary angiography was performed at the same week, otherwise at the end of 180th day. All patients had follow-up coronary angiography. Angiographic restenosis was defined as the presence of a 60% luminal diameter narrowing at the coronary angioplasty site. Angiographic restenosis occurred in 15 patients (47%). The sensitivity, specificity, positive predictive value and negative predictive values of the test were 93%, 41%, 58% and 88%, respectively. In patients with only left anterior descending artery lesion, the specificity and sensitivity of test increased to 67% and 100% respectively. We concluded that exercise treadmill test had high sensitivity and negative predictive value, but low specificity and positive predictive value in the detection of restenosis after percutaneous transluminal coronary angioplasty.
