About this trial
Angina is a feeling of chest pain or discomfort which can happen if there is reduced blood flow to the heart. Patients can experience angina with no obstructive coronary arteries (ANOCA) which is a difficult condition to treat (ie relieve angina) since few randomised, controlled therapy trials have been undertaken for ANOCA. Until now, angina has been mainly studied in men even though women are at least two-fold more likely than men to experience ANOCA.
In 2023, a Scientific Statement from the American Heart Association affirmed that resistance exercise training can improve or maintain muscle mass and strength and confer favourable physiological and clinical effects on cardiovascular disease and risk factors. Resistance exercise has not been assessed in ANOCA and it offers an important opportunity to study non drug alternatives to treatment for women.
This study will use a resistance based exercise programme to investigate if symptoms of ANOCA can be improved in women. It will recruit at least 76 patients (maximum 152 patients) across 13 hospitals in the UK and the Netherlands.
The study will use a randomised wait list control design. This means all participants will be offered the intervention, but the randomisation will decide when they undergo it.
It is part of a platform of trials for women with ANOCA. We are also setting up a drug study called ANOCA Therapy and a cohort study called ANOCA- Diagnosis.

Trial outcomes
Primary outcomes
Seattle Angina Questionnaire
The Seattle Angina Questionnaire a validated 19-item patient-reported survey used to measure coronary artery disease and angina treatment efficacy. Patients will complete on paper or electronically. The scores range from 0 to 100, with higher scores indicating less frequent angina, improved function, and better quality of life.
Secondary outcomes
Myocardial perfusion reserve (MPR)
The ratio of maximum blood flow in the heart muscle under stress compared to resting flow
Handgrip strength using hand dynamometer
Measured in Kgs. This is used as a proxy for overall body strength with lower measures indicating less strength.
Short Physical Performance Battery (SPPB)
Used as a proxy for fitness
Brief Illness perception Questionnaire (Brief IPQ)
A nine-item scale designed to rapidly assess the cognitive and emotional representations of illness. It consists of 9 items: 8 are scored on a 0-10 scale, and item 9 is an open-ended question assessing perceived causes. The total score (0-80) is calculated by summing the first 8 items, with items 3, 4, and 7 reverse scored. Higher scores generally reflect a more threatening perception of the illness
