Ultimate phases of hypertensive heart disease and stressed heart morphology by conventional and novel cardiac imaging.

Abstract

Early recognition of hypertensive heart disease is needed to prevent macrovascular and microvascular damage. Hypertension (HTN) is a risk factor for coronary artery disease, and plays a prominent role in the development of adverse left ventricular (LV) remodeling and heart failure. Here, we review new knowledge on effects of HTN on cardiac geometry and function, obtained from multimodality cardiac imaging, including echocardiography, positron emission tomography and magnetic resonance imaging. Early recognition of changes in LV geometry and function induced by HTN could identify patients at risk for end-organ damage, who could be targeted for close monitoring and intensive therapy. Basal septal hypertrophy as the early imaging biomarker at the adaptive phase may be a specific aspect not only in hypertensive heart but stress-related conditions and called stressed heart morphology.
