Does feature-tracking CMR identify variations in left ventricular myocardial strain and focal fibrosis in patients with resistant hypertension?
Feature-tracking CMR provides valuable information on the attenuation of myocardial deformation and focal fibrosis in response to long-standing high blood pressure.
• Variations of left ventricular strain are attributable to the degree of myocardial impairment in resistant hypertensive patients. • Focal myocardial fibrosis of the left ventricle is associated with attenuated global radial strain. • Feature-tracking CMR provides additional information on the attenuation of myocardial deformation responding to long-standing high blood pressure.
Chen et al. (Mon,) studied this question.
