Abstract
We investigated the association between in-hospital and peri-hospital mortality and body mass index (BMI)/waist circumference (WC) in a prospective acute coronary syndrome (ACS) registry in the Arabian Gulf. No significant associations with in-hospital mortality were found. Normal BMI had highest peri-hospital mortality, notably those with high WC. In logistic regression of mortality on obesity measures and potential confounders, the effects of obesity measures were no longer significant. In-hospital death increased by 5% with age and decreased by 42% in males. Mortality increased 3.7-fold with ST-elevation myocardial infarction (STEMI) and 3.0-fold with heart failure (HF) but decreased by 33% with dyslipidemia. Peri-hospital death increased by 4% with age and decreased by 30% in males. Mortality increased 2.8-fold with STEMI and 2.4-fold with HF. In- and peri-hospital mortality in ACS is significantly associated with age, gender, STEMI, HF, and dyslipidemia but not obesity measures.
