Risk factors such as diabetes mellitus (DM) have been associated with increased risk of mortality in patients with heart failure (HF). Obesity in diabetic patients worsens outcomes. However, there appears to be an obesity paradox in which stable HF patients with higher body mass index (BMI) have better survival. We sought to evaluate the association of DM and BMI with mortality in patients with end stage HF on palliative inotropic therapy. We performed a single center, retrospective chart review of HF patients who were placed on inotropes (milrinone or dobutamine) as palliative therapy from January 1, 2010 and followed up until October 1, 2019. Patients who received mechanical circulatory support or heart transplant were excluded. Patients were categorized by BMI (<25Kg/m2, 25-35Kg/m2 and >35Kg/m2). The primary outcome was all cause mortality. Multivariate cox proportional hazard regression model was used for analysis. 115 patients were included. Unadjusted analysis revealed significant relationship between mortality and coronary artery disease (HR 1.981; p value 0.01) and ischemic cardiomyopathy (HR 1.941; p value 0.01). After adjusting baseline characteristics using multivariate analysis (Table 1), mortality was associated wi...Continue Reading
