Brief Summary

Angina is the most common symptom of coronary heart disease among women but unlike men most women do not have stenosis of the coronary arteries. In a large proportion of these women, coronary microvascular dysfunction (CMD) is thought to be the cause of angina. However, CMD is also demonstrable in the asymptomatic population, and may merely be an innocent bystander related to the presence of cardiovascular risk factors rather than a cause of angina symptoms. The aim of this study is to determine whether comprehensive intervention is feasible and results in improvement in both angina and microvascular function in these patients.

Outcome Measures

Primary Outcomes (1)

  • Changes in coronary microvascular function

    Coronary microvascular function will be assessed by transthoracic Doppler stress echocardiography (TTDSE) and measured as Coronary Flow Velocity Reserve (CFVR). CFVR is a measure of microvascular dysfunction in the absence of upstream coronary stenosis. CFVR is the ratio of flow during stress and flow during rest and will be measured with TTDSE of the left anterior descending artery before and during infusion of high dose adenosine (0.14 mg/kg/min).

    Up to 24 months

Secondary Outcomes (8)

  • Changes in symptom burden assessed by the Seattle Angina Questionnaire (SAQ)

    Up to 24 months

  • Changes in biomarkers including inflammatory markers and markers of metabolism

    Up to 24 months

  • Changes in exercise capacity (VO2peak)

    Up to 24 months

  • Changes in body weight and fat distribution (DEXA scan)

    Up to 24 months

  • Changes in level of anxiety and depression (HADS questionnaire)

    Up to 24 months

  • +3 more secondary outcomes

Study Arms (2)

Weight loss, training, medication

EXPERIMENTAL

The intervention program consists of a comprehensive 24-week treatment period of: 1) Body weight loss without significant loss of muscle mass, through low energy diet combined with 2) Exercise training based on interval training and resistance exercise and 3) Optimal medical treatment for hypertension and hypercholesterolemia (with statin and ACE-inhibition). Further, participants in this allocation group receive nutrition counselling. The diet products are sponsored by Cambridge Weight Plan. No persons with interest in Cambridge Weight Plan will take part in the intervention phase, analyzing phase, data processing, or publication of data in this study.

Dietary Supplement: DietBehavioral: TrainingDrug: Medication (with statin and ACE-inhibition)

Control

NO INTERVENTION

The control group receives 24 weeks of usual care according to guidelines of Danish Cardiology Society. Treatment of angina pectoris in absence of coronary artery disease is normally provided by the patient's general practitioner and does not comprise intensive lifestyle intervention or medical treatment. If control group participants in this study need medical therapy for hypertension or hypercholesterolemia, this will be effectuated by the researcher, MD. Then, control participants will be monitored with blood pressure and LDL blood samples and receive medicine adjustments according to National Prevention Guidelines during the full study period.

Interventions

DietDIETARY_SUPPLEMENT

Weight loss achieved by following an evidence-based low energy diet of 800-1200 kcal/day for 12 weeks (Cambridge Weight Plan). Hereafter follow 12 weeks of 'weight maintenance' with consumption of normal heart healthy diet. Goal: total weight loss of at least 10% without significant loss of muscle mass. Monitored and supervised by a dietician

Also known as: Low Energy Diet
Weight loss, training, medication
TrainingBEHAVIORAL

Aerobic interval training and resistance exercise in group sessions twice weekly throughout the 24-week intervention. Training intensity individually adapted to the restricted calorie intake. Goal: Improved VO2 peak (at least 10%). Monitored by a physiotherapist.

Also known as: Aerobic Exercise Training
Weight loss, training, medication

Medical treatment for hypertension and/or hypercholesterolemia if systolic blood pressure \> 130 and/or low density lipoprotein (LDL) \> 2.0.
