Case report: assessment and management of myocardial infarction and non-obstructive coronary arteries (MINOCA): the role of microvascular coronary vasospasm.

Women with evidence of myocardial infarction with non-obstructive coronary arteries (MINOCA) and ischemia with non-obstructive coronary arteries (INOCA), a condition associated with adverse cardiovascular outcomes, are becoming increasingly recognized. Underlying mechanisms of MINOCA, such as coronary microvascular spasm, represent a diagnostic and therapeutic challenge to clinicians as there is currently neither a uniform nor comprehensive diagnostic strategy for accurate risk stratification for these patients. Diagnostic tests such as invasive coronary reactivity testing (CRT) can be useful in the diagnosis of MINOCA.
