About this trial

The evidence above demonstrates that microvascular dysfunction is an important determinant of patient prognosis, which however remains poorly classified. Given the high burden of disease and the severity of the functional impairment in these patients, the lack of a clear definition for this disease has a potentially large clinical importance. It is important to better describe the phenotype of these patients, identify the predictors of prognosis, and determine the impact of diagnosis.

Eligibility criteria

Qualifiers

Age ≥ 18 and <85 years.

Chronic coronary syndrome (including patients with anginal equivalents)

Evidence of reversible ischemia on non-invasive testing

Disqualifiers

Medical or psychological conditions that would jeopardize an adequate and orderly participation.

Left ventricular ejection fraction lower than 30%

Previous coronary artery bypass surgery (CABG) to all major branches in the LAD and left circumflex (LCX) territory, such that IMR cannot be measured
