Standardizing the Management of Patients With Coronary Microvascular Dysfunction (SAMCRO)

February 17, 2026 updated by: Consorzio Futuro in Ricerca

Standardizing the Management of Patients With Coronary Microvascular Dysfunction: the SAMCRO Trial

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:

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Seattle Angina Questionnaire
Time Frame: 1-year
The primary efficacy endpoint is the value of Seattle Angina Questionnaire (SAQ) summary score. The SAQ-SS ranges from 0 to 100 and higher values indicate better outcome
1-year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
EQ visual analogue scale
Time Frame: 1-year
The continuous value of EQ visual analogue scale (EQ-VAS). The EQ-VAS scale ranges from 0 to 100 and higher values indicate better outcome
1-year
Beck Depression Inventory (BDI)
Time Frame: 1-year
The continuous value of Beck Depression Inventory (BDI). BDI score ranges from 0 to 63. Higher scores indicate greater depressive severity.
1-year
Clinical adverse events
Time Frame: 1-year
Cumulative occurrence of death, and hospital admission for any cause
1-year
