Determinants of Cardiorespiratory Fitness and Effects of HIIT in Patients With ANOCA Obstructive Coronary Artery Disease(ANOCA)
What this study is about
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.
View original scientific description
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.
Interventions
BEHAVIORAL
EXERCISE TRAINING WITH OR WITHOUT MEDICATION
Remote 4 weeks of high-intensity interval exercise training on three non-consecutive days of the week.
Primary outcome measures
Examine cardiorespiratory fitness (change in VO2max in mL/kg/min) with cardiopulmonary exercise testing (CPET) Phenotype.
Time frame: 4 weeks
The investigators will assess VO2max (mL/kg/min) in 25 patients with ANOCA at the exercise laboratory.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
