Outcome Measures

Primary Outcomes (1)

  • SAQ questionnaire

    The pre-specified primary outcome criterion is the improvement in angina severity assessed by the Seattle Angina Questionnaire (SAQ SS - Summary Score) at 6 months from the start of treatment compared to baseline. It will be evaluated by the mean difference in change within the same patient in SAQ between the two groups at 6 months of treatment. The SAQ is a validated self-administered scale that allows assessment of angina severity, frequency, quality of life, and functional limitation. It is the most commonly used and validated patient-reported outcome measure for angina. The SAQ provides a scale for evaluating the severity of angina that has been shown to be valid, reproducible, and sensitive to changes.

Interventions

Beta-blockers are the first-line treatment for patients with stable angina secondary to classic epicardial atherosclerotic disease, where their clinical benefits are well-established (4). However, their efficacy has not yet been demonstrated in ANOCA patients with MVD, where beta-blockers are frequently used due to their physiological plausibility. Beta-blockers act by competitively inhibiting catecholamine receptors. The therapeutic benefits of beta-blockade in patients with stable angina are mediated by a reduction in myocardial oxygen demand. Myocardial oxygen demand depends on heart rate, contractility, and left ventricular wall tension, all of which are reduced with beta-adrenergic blockade. The reduction in wall tension is partly mediated by the antihypertensive action of these drugs. The decrease in heart rate occurs both at rest and during sympathetic activation such as exercise or stress. The negative inotropic effect of these drugs also contributes to reducing myocardial oxyg
