Polypill for Prevention of Cardiomyopathy

This study will investigate the utility of a polypill-based strategy for patients with type 2 diabetes mellitus and high risk of heart failure (HF), as assessed via the WATCH-DM risk score. Polypill therapy will consist of empagliflozin 12.5 mg, losartan 25, 50 or 100 mg, and finerenone 10 mg daily. The study duration is 6 months, and participants will be randomized to either polypill therapy or simultaneous prescription of the individual drugs. The primary outcome is change in peak VO2 and adherence to usual care. The investigators hypothesize that the use of a polypill is feasible and improves medication adherence and peak VO2 as compared to those receiving usual care.

Heart failure (HF) is a major cause of cardiovascular morbidity and mortality. One of the risk factors for HF is diabetes mellitus (DM). Altered glucose and lipid metabolism in DM leads to fibrosis and cardiac remodeling, ultimately causing ventricular dysfunction. While there is no consensus on the definition of "diabetic cardiomyopathy", broadly it can be defined as presence of pathological left ventricular hypertrophy, fibrosis and left ventricular diastolic/systolic dysfunction. A risk prediction score called "WATCH-DM" that includes clinical, laboratory and echocardiographic data has been developed to predict HF risk in those with type 2 DM. Every unit increase was associated with a 24% increase in relative risk of HF within 5 years. Drugs that decrease HF incidence could potentially be used in patients with Type 2 DM to alleviate HF burden. This many also improve medication adherence, which is poor for patients with polypharmacy. The rationale for the study is as follows: * Heart failure represents a major contributor to mortality, morbidity, and healthcare costs * Adherence to medications that prevent heart failure is low. * A polypill strategy is an innovative approach to heart failure prevention that also promotes adherence, especially in underserved population. The investigators propose a single-center, open-label, pragmatic, randomized study of 200 participants with T2DM and high risk of heart failure, as determined by a WATCH-DM risk score greater than or equal to 11. Duration of follow up will be 6 months. The target population is patients receiving care at UT Southwestern Medical Center or Parkland Health for Type 2 Diabetes Mellitus and high risk of heart failure. 100 participants will receive polypill and 100 will receive simultaneous individual prescriptions.The polypill will contain empagliflozin 12.5 mg, losartan 50 or 100 mg, and finerenone 10 mg and is dosed once daily. Our primary outcome will be the change in peak VO2 during a cardiopulmonary exercise test from baseline to 6 months. Secondary outcomes will include change in urine albumin creatine ratio, adherence, which will be assessed by the Morisky Medication Adherence Score - 8 (MMAS-8), pill count at baseline, 1 month and 3 months, and 6 months.
