title: Comparison of Long-Term Mortality for Cardiac Diseases in Patients With Versus Without Diabetes Mellitus.
abstract: Diabetes mellitus confers the highest mortality risk in primary and secondary cardiovascular prevention, but long-term prognosis differences between different forms of cardiovascular disease have not been assessed. We hypothesized that acute heart failure (HF) could have poorer outcomes than acute coronary heart disease (CHD) in patients with diabetes. We performed a prospective study of all consecutive patients admitted in a single year. Patients were categorized according to main cardiologic diagnosis: acute HF, acute CHD, rhythm disorders, or noncardiac disease. A total of 1,293 patients were included, 31.8% had diabetes and had higher mean age, more risk factors, previous cardiovascular disease, and co-morbidities. Hospital mortality (5.6% vs 1.7%; p <0.01) was higher in patients with diabetes. During follow-up (median 58.0 months; interquartile range 31.0 to 60.0), diabetic patients had higher cardiovascular mortality (27.2% vs 9.6%; p <0.01) and all-cause mortality (35.8% vs 14.5%; p <0.01); cardiovascular disease accounted for 75% of deaths. According to discharge diagnosis, patients with diabetes only had higher mortality rates in the subgroup of acute CHD. Acute HF was the diagnosis with higher cardiovascular (36.9%) and all-cause mortality (44.1%), followed by acute CHD (16.8% and 24.4%) and rhythm disorders (5.8% and 8.8%). Multivariate analysis identified an independent association with higher long-term mortality of acute HF and acute CHD in patients with and without diabetes. In conclusion, 1/3 of cardiology-admitted patients have diabetes and have poorer long-term prognosis, especially when discharged with the diagnosis of acute HF or acute CHD.
