Glucose Levels Predict Hospitalization for Congestive Heart Failure in Patients at High Cardiovascular Risk

Abstract
Background— Patients with diabetes mellitus (DM) are at high risk of developing congestive heart failure (CHF). However, the relationships between glucose levels and CHF in people with or without a history of DM have not been well characterized. Methods and Results— We evaluated the associations between fasting plasma glucose and risk of hospitalization for CHF during follow-up in patients at high cardiovascular risk and without CHF enrolled in a large-scale clinical trials program. Baseline fasting plasma glucose levels were assessed in 31 546 high-risk subjects with ≥1 coronary, peripheral, or cerebrovascular disease or DM with end-organ damage who are participating in 2 ongoing parallel trials evaluating the effects of telmisartan, ramipril, or their combination (Ongoing Telmisartan Alone and in Combination With Ramipril Global Endpoint Trial [ONTARGET]; n=25 620) and the effects of telmisartan against placebo in angiotensin-converting enzyme–intolerant patients (Telmisartan Randomized Assessment Study...
