Abstract

Background: Smoking is a challenge in secondary prevention after acute coronary syndrome (ACS). The objective was to assess whether the early anti-smoking intervention (ASI), in the acute hospitalization phase, improves the abstinence rate obtained during a cardiac rehabilitation program (CRP).

Methods: Multicenter clinical trial in which smoker patients admitted for ACS were randomized 1:1 to receive or not ASI from the first day of admission. Upon discharge, both groups were referred to the CRP, performing abstinence controls using co-oximetry. Patients lost were considered smokers.

Results: 72 patients were included, 58 men (80.5%), mean age 53 ± 8.1 years. They were admitted for ST elevation myocardial infarction 42 (58%), non-ST elevation myocardial infarction 29 (40%) and unstable angina 1 (1.3%). They smoked an average of 22 ± 11.3 cigarettes/day (pack-year index 37 ± 20). They completed the Richmond test (8.8 ± 1.3) and Fagestrom (5.69 ± 2.1). 36 patients (50%) were randomized to ASI, with no differences in the baseline characteristics of both groups. The dropout rate at the time of inclusion in CRP was higher in the ASI group (69 vs. 44%; p 0.034; OR 2.84), without statistical significance at discharge from the CRP (58 vs. 50%; p 0.478; OR 1.4) or at 12 months (58 vs. 44%; p 0.24; OR 1.75).

Conclusions: The ASI during admission significantly improves the smoking cessation rate at the time of inclusion in the CRP. Part of these beneficial effects are reduced in the follow-up losing statistical significance with respect to the control group.
