In Reply We thank Olafiranye for his interest in our work evaluating the effect of ischemic postconditioning in patients with ST-segment elevation myocardial infarction who are admitted for primary percutaneous coronary intervention.1 Smoking is a well-established risk factor for the development of cardiovascular disease.2 In this context, smoker’s paradox is a true paradox. The concept, first described in 1977 by Kitchin et al,3 was based on observations that current or previous smokers had a lower mortality after an acute myocardial infarction than nonsmokers. Similar data were subsequently recorded by others.4
