High-intensity interval training and causes of low cardiorespiratory fitness in people with ANOCA

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

Run by University of Virginia · NCT07182955 · Data updated 2026-11-12

This project will test whether a four-week remotely monitored high-intensity interval training (HIIT) program can safely improve fitness, heart function, and quality of life for adults with angina but no obstructive coronary artery disease (ANOCA).

Is this trial a fit for you?

Likely a good fit

Adults 18–85 with anginal symptoms and confirmed ANOCA on invasive or CT coronary angiography who can perform CPET, complete English questionnaires, use a wearable, and participate in intermittent high-intensity exercise.

Probably not a fit

People with systolic heart failure (LVEF <50% or NYHA class III), prior myocardial infarction or coronary revascularization, inability to safely perform CPET or HIIT, pregnant individuals, or those unable to participate in English are unlikely to benefit from this protocol.

What this trial studies

This interventional study will enroll 25 adults with angina and no obstructive coronary artery disease confirmed by invasive or CT coronary angiography. Participants will complete baseline cardiopulmonary exercise testing (CPET) and questionnaires on symptoms and quality of life, then undergo a four-week remotely monitored HIIT program with wearable monitoring. CPET and the same questionnaires will be repeated after training to measure changes in peak VO2 and to define CPET phenotypes that reflect cardiac, ventilatory, and muscle contributors to exercise limitation. Validated instruments including the Seattle Angina Questionnaire, SF-36, MacNew, CAQ, WLQ, and DASI will be used to capture symptom burden and functional status.

Why it matters

Potential benefit: If successful, the intervention could raise peak oxygen consumption (VO2peak), reduce anginal symptoms, and improve daily functioning and quality of life using an accessible remote exercise program.

How similar studies have gone: Previous HIIT studies in patients with coronary disease and heart failure have improved VO2peak and functional capacity, but HIIT and CPET phenotyping are relatively underexplored specifically in ANOCA.
