[Functional state of the myocardium in patients with renovascular hypertension]
Insights
Vasorenal hypertension doubles heart muscle mass and impairs function. Surgical correction reverses these effects, reducing heart muscle mass and improving contractility.
Area of Science:
- Cardiology
- Nephrology
- Vascular Surgery
Background:
- Vasorenal hypertension is a significant cause of secondary hypertension.
- Hypertension can lead to adverse cardiac remodeling, including myocardial hypertrophy.
Purpose of the Study:
- To investigate the impact of vasorenal hypertension on myocardial mass and function.
- To evaluate the effects of surgical correction of renal blood flow on cardiac parameters.
Main Methods:
- Studied 24 patients with vasorenal hypertension.
- Assessed myocardial mass and contractile function before and after surgical intervention.
- Monitored hypotensive effect post-surgery.
Main Results:
- Myocardial mass doubled in patients with vasorenal hypertension.
- Contractile and pumping functions of the myocardium were diminished.
- Surgical correction led to regression of myocardial hypertrophy.
- Improved myocardial contractile function was observed post-surgery.
Conclusions:
- Vasorenal hypertension causes significant cardiac remodeling.
- Surgical correction of renal blood flow effectively reverses cardiac changes associated with vasorenal hypertension.
Abstract:
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.
