The Effects of the Obesity Paradox and In-Hospital and One-Year Outcomes in Patients With ST Elevation Myocardial Infarction (STEMI): Results From a STEMI Registry.

Background: Obesity is strongly associated with increased cardiovascular diseases (CVD) and cardiovascular risk factors, such as diabetes mellitus, hypertension, and dyslipidemia. However, numerous studies have suggested the existence of an "obesity paradox" in which overweight and mildly obese patients often exhibit a better outcome than their leaner counterparts. Therefore, this study aimed to characterize the association between BMI and in-hospital and one-year outcomes.

Circadian pattern of symptom onset in patients with ST-segment elevation myocardial infarction in western Iran.

Background: Circadian variation is known as an important factor in acute myocardial infarction (AMI). Moreover, the circadian pattern may help in disease prevention and better medication prescription. Therefore, the aim of our study was to investigate the circadian pattern of symptom onset in patients with ST-segment elevation myocardial infarction (STEMI).
