[Functional state of the myocardium in patients with renovascular hypertension].

The authors studied the changes in the mass and contractile function of the myocardium in 24 patients with vasorenal hypertension before operation and in the late periods after surgical correction of the renal blood flow. It was found that in vasorenal hypertension the mass of the myocardium doubled while its contractile and pumping functions diminished. In the late periods after adequate surgical correction of renal blood flow with a good hypotensive effect hypertrophy of the myocardium regresses and its contractile function improves.
