Are you an adult with mild heart failure (HF) and left bundle branch block (LBBB)? LBBB is a heart condition in which there is a delay or blockage of electrical signals to the left side of the heart. This study is exploring the use of a treatment called cardiac resynchronization therapy (CRT) in people with HF and LBBB. To have CRT, participants must be willing to have an implanted device, called a biventricular pacemaker, that helps the chambers of the heart work together to pump blood more efficiently. To participate in this study, you must be at least 18 years old. This study takes place in Rochester, Minnesota.

Have you experienced a cardiac event in the past 6 months? This study assesses the efficacy of combining center-based and remote- or home-based cardiac rehabilitation sessions. Many patients who require cardiac rehabilitation, including those with angina myocardial infarction, heart failure, heart valve disease, and coronary heart (artery) disease, do not complete the necessary amount of rehabilitation sessions when done in a center-based environment. Researchers are investigating whether a combination approach will help. To participate in this study, you must be between 18 and 85 years old. This study takes place in Detroit, Michigan.
