Abstract
This study was performed to evaluate the importance of the duration of balloon inflation during PTCA, by comparing two common inflation durations. Patients were randomized to a 30-second inflation protocol (group I, 83 procedures, 109 lesions), or a 60-second protocol (group II, 83 procedures, 115 lesions). There were no differences in baseline characteristics between the two groups, and no subsequent differences in mean inflation number (3.4 +/- 1.6 vs 3.1 +/- 1.6), residual stenosis (34% +/- 17% vs 33% +/- 16%), presence of dissection (29% vs 34%), or clinical success (89% vs 84%), group I versus group II, respectively. The 30-second inflations caused significantly less chest pain score (147 +/- 239 vs 399 +/- 516, P less than 0.001), and ST segment alteration (75 +/- 94 seconds vs 136 +/- 163, P less than 0.05). These results indicate that 60-second inflations do not produce a superior result to 30-second inflations. Furthermore, shorter inflations are much better tolerated.
