Type 2 diabetes is an important risk factor for heart failure and is common in patients with heart failure. The objective of the study was to examine all-cause mortality in relation to weight status in patients with type 2 diabetes hospitalized for decompensated heart failure. The Worcester Heart Failure Study included adults admitted with acute heart failure to all metropolitan Worcester medical centers in 1995 and 2000. The weight status of 1644 patients with diabetes was categorized using body mass index calculated from height and weight when patients were admitted. Sixty-five percent of patients were overweight or obese and 3% were underweight. Underweight patients had 50% higher odds of all-cause mortality within 5 years of hospitalization
