Long-term treatment in arterial hypertension for protecting hypertrophic myocardium.

Abstract：

:The cardiac organ manifestation of arterial hypertension comprises the myocardium itself with left-ventricular hypertrophy, the interstitium with perivascular and interstitial fibrosis, and the coronary circulation with disease of large and small coronary arteries. The consequences of the sum and interactions of these cardiac organ manifestations have an impact on left-ventricular systolic and diastolic function, the ischemic risk, and the occurrence of arrhythmias in hypertensive patients. As the prognosis of arterial hypertension is determined, to a considerable extent, by these cardiac complications, the aim of treatment of hypertensive heart disease is reversal of the myocardial hypertrophy in order to prevent later progression to hypertensive failure. A further goal of therapy is reversal of hypertensive coronary microangiopathy in order to improve the coronary reserve and to reduce the ischemic risk. Regression of hypertrophy can be induced by suitable antihypertensive drugs (calcium channel blockers of the dihydropyridine type, ACE inhibitors, and sympatholytic substances). While normal systolic function was maintained in the compensated stage of hypertensive hypertrophy and was not significantly influenced by antihypertensive therapy, diastolic function was impaired in a very early stage of arterial hypertension. Both the phase of isovolumic relaxation and the phase of early diastolic filling were imparied, while after long-term antihypertensive treatment with Ca-channel blockers of the dihydropyridine type or ACE inhibitors, only the latter one was improved. From preliminary results there is clinical evidence that hypertensive disease of small coronary arteries can be reversed after long-term antihypertensive treatment with a consequently improved coronary reserve and a reduced ischemic risk. Moreover, to what extent the prognosis of hypertensive heart disease can be improved by reversal of myocardial hypertrophy and disease of small coronary arteries is yet unknown.
