Determinants of Cardiorespiratory Fitness and Effects of HIIT in Patients With ANOCA Obstructive Coronary Artery Disease(ANOCA)
Determinants of Cardiorespiratory Fitness and Effects of High Intensity Interval Training (HIIT) in Patients With Angina and No Obstructive Coronary Artery Disease (ANOCA)
University of Virginia

INTERVENTIONAL
Conditions
Summary
The main goal is to understand what causes reduced fitness in ANOCA and whether targeted exercise can help improve it. This study aims to better understand why patients with Angina and No Obstructive Coronary Artery Disease (ANOCA) have poor cardiorespiratory fitness and its effect on quality of life. Investigators also want to see if a structured high-intensity exercise program (HIIT), done with remote monitoring, can safely improve heart function, fitness, and quality of life in these patients. The Investigators will use a special exercise test called cardiopulmonary exercise testing to look for patterns that can help explain exercise limitations and quality of life in ANOCA before and after a remote high-intensity exercise program.
