Smoking as a Risk Factor for Recurrence of Sudden Cardiac Arrest

Abstract
We obtained information about cessation of smoking in 310 survivors of out-of-hospital cardiac arrest who had been habitual cigarette smokers at the time of their arrest. Patients with coronary heart disease were stratified according to mortality risk on the basis of recognized criteria. The expected first-year rate of recurrent arrest ranged from 2 to 40 percent among the strata.
