Primary Outcome Measures

Name	Time	Method
Prevalence of coronary vasomotor dysfunction	Baseline	Can be handled as dichotomous outcome with normal vs abnormal coronary function test (CFT) results. Alternatively, can also be handled as categorical outcome with the following categories.; 1. Normal CFT results; 2. Vasospastic endotype (epicardial or microvascular); tested by acetylcholine provocation; 3. Microvascular dysfunction endotype (decreased coronary flow reserve or increased index of microvascular resistance); tested by bolus thermodilution, optionallly with additional continuous thermodilution method; 4. Mixed endotype

Secondary Outcome Measures

Name	Time	Method
Angina burden	Baseline and every year up to 5 years after baseline	Measured by Seattle Angina Questionnaire summary score, 0-100 with higher scores indicating better (functional) status.
Experienced quality of life	Baseline and every year up to 5 years after baseline	Measured by Short Form 36, 0-100 with higher scores indicating better quality of life
