Clinical Trials

This research will investigate whether the stress response physiology and autonomic function in response to mental stress are different in women with CMD compared to other groups.

Are you a current patient at Massachusetts General Hospital or Brigham and Women’s Hospital with clinical depression and heart failure or unstable chest pain (called angina)? This study is investigating whether 26 weeks of education and increased monitoring from healthcare managers improves psychiatric and heart symptoms better than self-managed care. This study takes place in Boston, Massachusetts.

To determine the mechanism of monocyte priming in humans, the study team will conduct a complete feeding trial in normal weight and metabolically healthy human subjects (20-45 years of age) using a western diet (WD), characterized as being high-saturated fat, high-fructose, and high-calorie for 8 weeks.

The Together Everyone Achieve More (TEAM) Physical Activity trial evaluates the efficacy of a group-based social affiliation intervention (vs. a standard group-delivered physical activity comparison program) for increasing physical activity among inactive African American women. Using a group cohort randomized design implemented at community centers across five years, the primary aim of this study is to evaluate the efficacy of the 10-week TEAM-PA group-based intervention (vs. comparison program) on increasing daily total physical activity from baseline to post-intervention and maintenance at a 6-month follow-up.

The study aims to determine the minimally effective dose combination(s) of frequency and duration needed to provide cardiometabolic benefit during an 8-hour experimentation period.

This study will identify and test the physiological effects of several sedentary behavior interruption strategies and explore the feasibility (i.e., likelihood of an individual performing the requested activities) of those strategies to inform the development of public policy surrounding sedentary behavior interruption. Long-term, the findings of this study will inform a large clinical trial that can test whether sedentary behavior reduction can decrease cardiovascular disease risk.

This study aims to evaluate the effect of estradiol with or without a prior gonadotropin releasing hormone analogue on insulin sensitivity and vascular function in transgender females compared to cisgender controls.

The purpose of the study is to evaluate how dietary habits in the post-surgical year impact outcomes of bariatric surgery.

The overarching goal of the proposed study is to develop and test an enrichment to Nurse-Family Partnership (NFP) using an existing, evidence-based program to improve clients' and their children's cardiovascular health from early pregnancy to 24 months postpartum. With support from NFP supervisors and nurses, the investigators will develop new NFP materials promoting healthy diet, activity, sleep, and smoking behaviors, along with optimal weight, glycemia, lipid, and blood pressure profiles. The investigators will conduct a pilot study with 40 prenatal or postpartum NFP clients and their nurses to determine feasibility and acceptability of the materials and study protocol.

Do you have overweight? Circadian rhythm disorders can cause overweight and obesity. This study is examining how not getting enough sleep causes these complications. To participate in this study, you must be between the ages of 20 and 40 and have overweight but not obesity. This study is located in New York, New York.
