Utility of the ACC/AHA lesion classification as a predictor of procedural, 30‐day and 12‐month outcomes in the contemporary percutaneous coronary intervention era

Background Correlations between the ACC/AHA coronary lesion classification and clinical outcomes in the contemporary percutaneous coronary intervention (PCI) era are not well established. Methods We analyzed clinical characteristics and outcomes according to ACC/AHA lesion classification (A, B1, B2,...

Description
Summary:Background Correlations between the ACC/AHA coronary lesion classification and clinical outcomes in the contemporary percutaneous coronary intervention (PCI) era are not well established. Methods We analyzed clinical characteristics and outcomes according to ACC/AHA lesion classification (A, B1, B2, C) in 13,701 consecutive patients from the Melbourne Interventional Group (MIG) registry. Patients presenting with STEMI, cardiogenic shock and out‐of‐hospital cardiac arrest were excluded. The primary endpoints were 30‐day and 12‐month mortality. Secondary endpoints were procedural success as well as 30‐day and 12‐month major adverse cardiac events. Results Of the 13,701 patients treated, 1,246 (9.1%) had type A lesions, 5,519 (40.3%) had type B1 lesions, 4,449 (32.5%) had Type B2 lesions and 2,487 (18.2%) had Type C lesions. Patients with type C lesions were more likely to be older and have impaired renal function, diabetes, previous myocardial infarction, peripheral vascular disease and prior bypass graft surgery (all P
