The prognostic significance of smoking cessation after acute coronary syndromes: An observational, multicentre study from the Melbourne interventional group registry

Abstract

Objective We aim to ascertain the prognostic significance of persistent smoking and smoking cessation after an acute coronary syndrome (ACS) in the era of percutaneous coronary intervention (PCI) and optimal secondary prevention pharmacotherapy. Methods Consecutive patients from the Melbourne Interventional Group registry (2005-2013) who were alive at 30 days post-ACS presentation were included in our observational cohort study. Patients were divided into four categories based on their smoking status: non-smoker; ex-smoker (quit >1 month before ACS); recent quitter (smoker at presentation but quit by 30 days) and persistent smoker (smoker at presentation and at 30 days). The primary endpoint..
