Myocardial Strain and Stiffness Parameters as a Novel Target of Antihypertensive Treatment

In the review, the clinical significance of increased myocardial stiffness and strain impairment in the settings of arterial hypertension is considered. The mechanisms of increasing myocardial stiffness as a part of hypertensive heart disease are presented. Particular attention is paid to the role of the sympathetic nervous system activation as one of the triggers that induce the connective tissue alteration of cardiac interstitium. The possibilities of echocardiography in the early noninvasive detection of myocardial strain abnormalities are discussed. New ultrasound parameters for describing stiffness properties of the heart are presented. From the evidence-based medicine point of view, the prognostic significance of increasing myocardial stiffness as a risk factor of the adverse cardiovascular events, as well as the possibility of its management with different antihypertensive drugs, is considered. Finally, there are presented clinical trials data, indicating high potential of the highly selective ^1-adrenoblocker bisoprolol for of correction myocardial stiffness and strain impairment.
