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.

Do you have stable angina and myocardial bridging but not obstructive coronary artery disease (CAD)? This study aims to help improve treatments for people that have angina in the absence of obstructive CAD. Angina without CAD affects millions of people but remains underdiagnosed and treatments are lacking. To participate in this study, you must be between 18 and 80 years old. This study takes place in Stanford, California.

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

Do you have a high-risk pregnancy? This study will investigate the use of a non-invasive scan called fetal magnetocardiography to detect potential problems in the fetus in five high-risk pregnancy conditions associated with stillbirth. The scan is normally used to look at fetal heart rhythms. To participate in this study, you must be at least 18 years old and pregnant with one of the following: having a stillbirth in a previous pregnancy, carrying identical twins, or having a fetus that has been diagnosed with major congenital heart disease, fetal hydrops, or fetal gastroschisis. This study takes place in Madison and Milwaukee, Wisconsin.

Are you a woman who is postmenopausal or a man older than 65? This study will investigate the effects of oral progesterone for older women and testosterone for older men on QT intervals. QT intervals that are increased by medicine can lead to dangerous heart rhythm problems. Researchers hope to learn more about why this happens and how to deliver safer doses. This study is located in Indianapolis, Indiana.

The study is designed to assess the usability of a novel CPAP human interface compared to a traditional nasal mask. Human subjects will interact with two different CPAP interfaces including a traditional CPAP mask and the 2nd generation DreamPort-Eclipse. Subjects will be requested to put on each of the different CPAP interface options a total of three times for a total of 6 trials. The order of device will be randomized.

The purpose of this research study is to see if obstructive sleep apnea (OSA) is associated with abnormalities in fat metabolism. Through this research study, the Investigator will evaluate how fat is metabolized in people with and without sleep apnea, what substances the fat tissue releases, and how these substances might change the way the body uses energy and sugar.

This research study is designed to learn, first, whether two anesthetics have different effects on collapse seen within the upper airway during sleep endoscopy. A second purpose is to learn whether collapse at several levels of the upper airway is associated with obstructive sleep apnea that persists after adenotonsillectomy, the surgery that removes the tonsils and adenoids.

This double-blind placebo-controlled parallel group randomized study design will be used to test whether 4 weeks of atorvastatin 10 mg daily reduces levels of inflammatory markers in OSA patients treated with CPAP (standard of care). The purpose of this study is to investigate: 1) whether statins reduce endothelial inflammation and pro-thrombotic conditions in OSA, including in patients adherent to CPAP (Aim 1); and 2) whether statins reduce endothelial inflammation and pro-thrombotic conditions by improving endothelial cholesterol metabolism and trafficking in OSA (Aim 2).
