Conclusion
The occurrence of a major surgical procedure seems to have beneficial psychological effects, representing an interesting setting for smoking cessation counseling to have higher chances of success.
Methods
Smokers submitted to myocardial revascularization were divided into CABG and PCI groups. The research was conducted through interviews at the Hospital Santa Lucinda outpatient clinic. Patients with smoking cessation longer than 90 days before hospital admission, combined procedures, hospital readmission before 360 days after discharge, cases of death at any time, and emergency procedures were excluded from the study. The start of the smoking cessation period was determined as just after hospital discharge, with a follow-up of 12 months.
Objective
To study the rate and perpetuation of smoking cessation after myocardial revascularization comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI).
Results
The proportion of patients reporting smoking relapse was significantly lower in the CABG than in the PCI group at 30 (11.1% vs. 20.8%; P=0.039) and at 180 days (23.1% vs. 41.5%; P=0.002), but no differences were observed between the two groups at 360 days after hospital discharge (51.9% vs. 54.1%; P=0.719). High levels of nicotine dependence and passive smoking showed to be important predictors of smoking relapse in the long-term.
