Why the study?
Does smoking affect the clinical profile and in-hospital outcome in patients with a first documented myocardial infarction?
Does smoking affect the clinical profile and in-hospital outcome in patients with a first documented myocardial infarction?
Smokers presenting with a first myocardial infarction paradoxically have a better in-hospital prognosis than non-smokers, despite evidence of higher peak cardiac enzymes.
Answers are grounded in this paper and cite their sources.
Smokers' better in-hospital prognosis after first MI is hypothesis-generating; does not support changes in smoking cessation practice.
Nine hundred and seventy eight patients with a first documented myocardial infarction were studied to detect smoking related differences in clinical profile and in-hospital outcome. The distribution of infarct sites differed significantly between smokers and non-smokers. Smokers had higher peak cardiac enzyme concentrations. In spite of this, smokers had a better prognosis than non-smokers. There are important differences between smokers and non-smokers, both in clinical profile and in-hospital outcome, which may reflect a difference in the nature of the underlying coronary disease.
