BD = balloon dilation; LAD = left anterior descending coronary artery; NC = noncompliant balloon; RCA = right coronary artery; TIMI = Thrombolysis In Myocardial Infarction; other abbreviations as in Tables 1 and 2.

  • Student t test for continuous variables, Fisher exact test for type of lesion, diffuse, ostial, culprit, complete revascularization, and noncompliant BD post-dilation, and chi-square test for other qualitative ones.
