Hi friend, Welcome to Health Care Magic Micro-vascular angina is possible – but more often, it is a diagnosis by exclusion. A thallium stress treadmill exercise test may help. Coronary angiogram (may be even with provocative tests) is generally needed to exclude obvious and easily treatable large artery lesions. Cardiomyopathy may need to be excluded. Rather than rushing each time, you ought to have planned visits and appropriate investigations – to arrive at proper diagnosis. Because, proper treatment depends on proper diagnosis. Take care Wishing speedy recovery God bless Good luck
