Stockholm Myocardial Infarction With Nonobstructive Coronaries Study 3 (SMINC-3)
March 14, 2023 updated by: Per Tornvall, Karolinska Institutet
Stockholm Myocardial Infarction With Nonobstructive Coronaries Study 3 - Pilot Study of Prevalence of Coronary Microvascular Dysfunction in Myocardial Infarction With Nonobstructive Coronary Arteries
The present pilot study will investigate the prevalence of CMD in an unselected cohort of patients with the working diagnosis MINOCA and to study if the diagnostic yield can be improved by adding adenosine to the CMR investigation.
Patient will be their own controls.
