Smoking prevalence in coronary patients from EuroAspire III Romania

Abstract

Objective: Evaluating smoking incidence, the compliance to smoking cessation recommendation and benefits of quitting smoking in coronary patients included in EuroAspire III Romania survey.

Materials and methods: We evaluated the acute cardiovascular events (MACE) incidence in 530 consecutive coronary patients (> or = 18 years and < 80 years at the time ofidentification) with first or recurrent clinical diagnosis or treatments for coronary heart disease, retrospectively identified from diagnostic registers or hospital discharge lists. The coronary events for hospital admission were: elective or emergency coronary artery by-pass graft (CABG), elective or emergency percutaneous transluminal coronary angioplasty (PTCA), acute myocardial infarction (AMI) and unstable angina (UA). The starting date for identification was not less than 6 months and not more than 3 years prior to the expected date ofinterview. Patients were divided in three groups according to their condition of smoker (smoking at interview moment), ex-smoker (quitting smoking prior to interview moment) and no smoker (never smoking).

Results: Smoking incidence before hospital admission for coronary event was 68.3% and 10% after hospital discharge. Prior the coronary event, percentage of male smokers (77.15%) predominated by female smokers (42.64%) - p<0.05, OR=4.54. Male smokers (67.25%) were more compliant to smoking cessation recommendation compared to females (32.35%) - p=0.04, OR=2.16; there was no significant difference between the two sexes concerning smoking incidence at interview moment (p>0.05). Patients who continued smoking after hospital discharged presented an increased frequency of MACE compared to non smokers (p=0.043, OR=1.98). Also, patients who continued smoking till hospitalization for coronary event, presented a higher risk compared to non smokers concerning re-intervention by PTCA (p=0.017, OR=4.28) and AMI incidence (p=0.01, OR=4.89). The MACE incidence was higher in active smokers versus passive smokers, but there was no significant differences between the two groups (p>0.05).

Conclusion: Majority of coronary patients renounced smoking after their first experience with cardiovascular events, a small part continued smoking. Patients who continued smoking after the acute event had higher incidence of MACE compared to non-smokers or ex-smokers (p<0.05). Also, MACE incidence was higher in active smokers versus passive but the difference was not significant between the two groups (p>0.05).
