Summary

Coronary Microvascular Dysfunction (CMD) occurs when there are problems in the small blood vessels/arteries of the heart, resulting in persistent chest pain that affects women.

There are an estimated 3 million women in the US with CMD and about 100,000 new cases annually. 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. The autonomic nervous system (ANS) controls normally involuntary activities, such as heart rate, respiration (breathing), body temperature, blood pressure, and urinary function. This study will also examine how chronic and daily life mental stress affects the heart and blood vessels.

Participants from this study will be recruited mainly from Emory Healthcare-associated hospitals, the Emory Heart Disease Center for Prevention, and Emory Healthcare outpatient cardiology clinics. Participants will have physical exams, blood tests, stress tests, exercise tests, surveys, questionnaires, and images taken of their hearts and blood vessels. They will be asked to take home devices to monitor their autonomic function, sleep, and track their mood, stress level, and symptoms for one week. Data and specimens will be saved for future research.

Study Procedures

All participants will answer a series of questionnaires that address several factors such as patient medical history, family history, medication usage, health behaviors, psychological factors, etc. Questionnaires related to symptoms, psychological factors, depression, anxiety, and quality of life will be taken. All participants will undergo 123I-MIBG SPECT imaging in the morning in a fasting state. Mental Stress Testing will be conducted in the Laboratory in the morning after fasting for at least 4 hours and withdrawal of all vasoactive medications, caffeine, and tobacco 24-48 hours before testing. Participants will also undergo 1-week of Home Monitoring using a single-use, noninvasive, water-resistant, 7-day ambulatory ECG monitoring, which offers the advantage of direct access to raw data that can be downloaded from the device after use. A 3-day food recall diary, cognitive assessments via the NIH Toolbox, and a Sleep diary during home monitoring will be collected.
