Multicenter Registry on Microvascular Dysfunction - Searching a New Ach Spasm Definition (MICRO-SNAPE)
November 4, 2023 updated by: Tommaso Gori, Johannes Gutenberg University Mainz
A Multicenter regIstry on the Diagnosis of Patients With Chronic Angina and no Angiographic coRonary Artery Stenosis (International Retrospective Collection of Anonymized Patient Data) - Searching a New Ach Spasm Definition
The MICRO-SNAPE registry will collect data from patients undergoing investigation of microvascular dysfunction and coronary spasm in Europe and North America.

Detailed Description
Microvascular dysfunction is an important determinant of patients´quality of life and 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 understanding and diagnosis has a potentially large clinical importance.
It is therefore important to better describe the phenotype of these patients.
The MICRO-SNAPE registry will allow investigating these associations.
Patient data as collected during the local clinical practice and at the operator's discretion, will be entered in this non-interventional registry.
