VILCHES IZQUIERDO, Ernesto et al. Smoking and alcohol and coffee consumption as risk factors for sudden cardiac death. Rev cubana med [online]. 2014, vol.53, n.3, pp. 325-336. ISSN 0034-7523.

Objective: describe the role of smoking and alcohol and coffee consumption as risk factors in the cases of sudden cardiac death (SCD) recorded at Julio Trigo López Hospital in the period 2007-2011. Methods: analytical observational unmatched case-control study. Results: it was found that smoking (OR= 4.08) and alcohol consumption (OR= 1.70) exhibited a strong statistical association with the cases of sudden cardiac death. On the other hand, evaluation of the presence of lesions on the coronary vascular tree revealed a strong positive statistical association mainly in the group of cases with OR= 5.5 for the variable smoking and OR= 4.8 for alcohol consumption. A fresh coronary thrombus and/or AMI were responsible for 63.8% of the cardiovascular deaths. This was particularly significant in the group of deaths due to cardiac causes (p= 0.000), reaching 75.5 % of the cases. Conclusions: in both study groups, smoking showed strong statistical significance, but it was predominant in the SCD group. Alcohol consumption was found to be a potential RF in SCD cases. The presence of significant atherosclerotic lesions in both groups confirms its status as a RF. The potentially beneficial effect of coffee could not be determined, for it was accompanied by smoking. Hence the impossibility of controlling the variable.
