Remodeling and regression of left ventricular hypertrophy in patients with arterial hypertension (literature review)

Abstract

The article contains literature information concerning the pathogenesis of hypertrophy and remodeling of the left ventricle (LV) of the heart in patients with arterial hypertension (AH), regression of left ventricular hypertrophy (LVH) under the influence of anti-hypertensive treatment. Remodeling of the heart is its structural geometrical changes occurring under the influence of pathological factors: increasing the number of sarcomeres, length and thickness of cardiomyocytes, increasing or decreasing the wall thickness, and enlargement of the ventricular cavity. The renin-angiotensin-aldosterone system (RAAS) plays a central role in the pathogenesis of hypertrophy and remodeling of the myocardium with AH and heart failure. LVH is one of the most significant predictors of cardiovascular events, including myocardial infarction, stroke, life-threatening ventricular arrhythmias, mortality from cardiovascular diseases, and general mortality. Treatment with angiotensin-converting enzyme inhibitors (ACEI), dihydropyridine calcium channel blockers (CCB), АТ ІІ receptor blockers (ARB) promotes reverse development of LVH and regression of the processes of the heart muscle remodeling. ACEIs are found to be more effective in achieving regression of LVH in patients with AH compared to CCB and beta-blockers. An early beginning of anti-hypertensive therapy and attention to metabolic aspects are critically important to avoid irreversible LVH. The ESH/ESC recommendations (2018) indicate that ACEI and ARB are effective for the prevention or regression of LVH in patients with AH, and beta-blockers are less effective than RAAS blockers and CCB.Objective: to systematize literature data about the pathogenesis of the left ventricle remodeling in patients with arterial hypertension, and the role of anti-hypertensive therapy in the regression of left ventricular hypertrophy. Conclusion. Today, the concept about the role of the renin-angiotensin-aldosterone system in the pathogenesis of hypertrophy and remodeling of the left ventricle in patients with arterial hypertension has been formulated. Angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers are the most effective in the prevention or regression of left ventricular hypertrophy in patients with arterial hypertension.
