Summary

The aim of this study is to assess microvascular function as determined by a cardiovascular magnetic resonance measurement of whole-heart (global) perfusion reserve. The goal is to determine the prevalence of MVD in two common forms of non-ischemic cardiomyopathy, hypertrophic cardiomyopathy (HCM) and idiopathic dilated cardiomyopathy (IDCM). The hypothesis that an optimized technique will provide robust detection of MVD and that a multifaceted approach will provide new insights into the pathophysiology of MVD, including the influence of myocardial scarring upon the presence and severity of MVD.

Conditions

Interventions

DRUG

Regadenoson

Microvascular disease will be considered present if regional perfusion defects are observed or global perfusion reserve is reduced. For the assessment of microvascular disease, the adenosine and regadenoson groups will be combined, as the medications are considered interchangeable.
