Objective To evaluate relation between smoking in 1 year events in cardiac death in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).

Methods 624 consecutive patients (506 male, 118 females) with STEMI undergoing primary PCI were enrolled, including 319 smoking female (63.0%), 187 nonsmoking (37.0%). To observe the relation between smoking and 1 year cardiac death in male.

Result Male have 25 cases cardiac death (4.9%), including 11 deaths in administration (2.1%), smoking 23 cases (4.5%), nonsmoking 2 cases (0.39%) p=0.001. Multivariate liner regression analysis showed that active smoking is associated with SYNTAX score in coronary artery lesions (p=0.019). Logistic regression analysis showed a significant relationship between active smoking and 1 year cardiac death (OR, 3.472; 95% CI 3.035 to 3.762; p=0.021).

Conclusion Active smoking is related with 1 year cardiac death. Male active smoking is not only the independent risk factor with cardiac death, but also the risk of adverse prognosis after intervention.
