Obesity paradox: Clinical benefits not observed in obese patients with ST-segment elevation myocardial infarction: A multicenter, prospective, cohort study of the northern region of China

摘要

A significant increase in the incidence of coronary heart disease has been reported in obese populations. However, many cohort studies and several cross-sectional analyses and retrospective studies have found that among patients with coronary heart disease, obese patients had a better cardiovascular prognosis, and this has been called the "obesity paradox" [1-4]. Studies to date have described the clinical manifestations, treatment, and outcomes of obese patients with acute myocardial infarction but have focused mainly on the populations of Western countries [5,6]. Obesity and the proportion of obese individuals in the Chinese population differ significantly from those in Western countries due to racial differences.
