Summary

The SAMCRO is an all comers, prospective, randomized, multicenter, open-label study with blinded adjudicated evaluation of outcomes (PROBE). The diagnosis of angina in non obstructive coronary artery disease (ANOCA) will be confirmed with coronary artery angiography and with the invasive assessment of coronary microvascular dysfunction (CMD) and coronary vasomotion. At least 120 ANOCA patients with invasively confirmed CMD will be randomized to i) multi-domain lifestyle intervention (experimental arm) vs. ii) standard of care (control arm). All patients will undergo follow-up visits at 6, 12, 24, 36, 48 and 60 months. The study endpoints will be the improvement of angina status and quality of life as assessed by validated questionnaires at one year. All participants in the multi-domain lifestyle group will receive five different kinds of intervention: i) dietary counselling, ii) strict management of cardiovascular (CV) and metabolic risk factors, iii) tailoring of medical therapy on the basis of the invasive assessment of CMD and coronary vasomotion, iv) exercise training and v) psychological intervention. Patients randomized to the control group will be managed according to current guidelines. The angina status will be assessed by the Seattle Angina Questionnaire (SAQ). Quality of life will be assessed using the EuroQoL (EQ5D-5L). Anxiety and depression will be assessed using the Beck Depression Inventory (BDI).

Detailed description

The aim of the SAMCRO trial is to determine whether a multidomain lifestyle intervention improves angina status and quality of life in ANOCA patients as compared to current standard of care. Patients will be randomized to: EXPERIMENTAL ARM: MULTI-DOMAIN LIFESTILE INTERVENTION Patients will receive five different kinds of intervention: i) strict management of CV and metabolic risk factors, ii) tailoring of medical therapy on the basis of the invasive assessment of CMD and coronary vasomotion, iii) dietary counselling, iv) exercise training v) psychological counselling CONTROL ARM: STANDARD OF CARE Patients randomized to the control group will be managed according to current guidelines
