Key result
Current smoking is linked to ~51-fold higher odds of harmful alcohol use post-ACS.
Why the study?
The relationship between alcohol abuse and cardiovascular disease, particularly coronary heart disease, remains controversial and requires further investigation after ACS.

BACKGROUND: Some studies have indicated alcohol abuse as one of the contributors to the development of cardiovascular disease, particularly coronary heart disease. However, this relationship is controversial. OBJECTIVE: To investigate the relationship between post-acute coronary syndrome (ACS) alcohol abuse in the Acute Coronary Syndrome Registry Strategy (ERICO Study). METHODS: 146 participants from the ERICO Study answered structured questionnaires and underwent laboratory evaluations at baseline, 30 days and 180 days after ACS. The Alcohol Use Disorders Identification Test (AUDIT) was applied to assess harmful alcohol consumption in the 12 months preceding ACS (30 day-interview) and six months after that. RESULTS: The frequencies of alcohol abuse were 24.7% and 21.1% in the 12 months preceding ACS and six months after that, respectively. The most significant cardiovascular risk factors associated with high-risk for alcohol abuse 30 days after the acute event were: male sex (88.9%), current smoking (52.8%) and hypertension (58.3%). Six months after the acute event, the most significant results were replicated in our logistic regression, for the association between alcohol abuse among younger individuals [35-44 year-old multivariate OR: 38.30 (95% CI: 1.44-1012.56) and 45-54 year-old multivariate OR: 10.10 (95% CI: 1.06-96.46)] and for smokers [current smokers multivariate OR: 51.09 (95% CI: 3.49-748.01) and past smokers multivariate OR: 40.29 (95% CI: 2.37-685.93)]. CONCLUSION: Individuals younger than 54 years and smokers showed a significant relation with harmful alcohol consumption, regardless of the ACS subtype.

Morilha et al. (2015) conducted a cohort in Post-Acute Coronary Syndrome (n=146). Current smoking vs. Never smoking was evaluated on High-risk alcohol abuse (AUDIT score ≥ 8) at 180 days post-ACS (OR 51.09, 95% CI 3.49-748.01). Current smoking was significantly associated with a markedly higher risk of harmful alcohol consumption 180 days after an acute coronary event compared to never smoking (OR 51.09).
