Effect of nicotine replacement therapy on cardiovascular outcomes after acute coronary syndromes.

Abstract

The optimal approach to encourage smoking cessation after acute coronary syndrome (ACS) remains unclear. The safety of nicotine replacement therapy (NRT) after ACS is not well established. The aim of the present study was to determine the relationship between NRT use and adverse cardiovascular outcomes after ACS. Using a pre-existing database, 663 smokers with ACS were identified. The patients were separated into the NRT (n = 184) or control (n = 479) groups according to whether NRT was prescribed on hospital discharge. Multivariate logistic regression analysis was used to account for the baseline differences between the 2 groups. Of the 663 patients, 202 had adverse events in the first year after ACS. No significant differences were seen with NRT use for the 1-year combined end point of death, myocardial infarction), repeat revascularization, or rehospitalization for angina, congestive heart failure or arrhythmia (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.61 to 1.30, p = 0.54). There were no differences in the individual 1-year end points of death (odds ratio 0.80, 95% confidence interval 0.33 to 1.91, p = 0.61), myocardial infarction (odds ratio 0.90, 95% confidence interval 0.40 to 2.06, p = 0.80), repeat revascularization (odds ratio 0.77, 95% confidence interval 0.44 to 1.36, p = 0.37), or rehospitalization for angina, congestive heart failure, or arrhythmia (odds ratio 1.01, 95% confidence interval 0.66 to 1.53, p = 0.97). In conclusion, NRT use was not associated with an increased risk of adverse cardiovascular events in the first year after ACS.
