Regression of left ventricular hypertrophy during treatment with antihypertensive agents
Insights
Antihypertensive therapy can reverse left ventricular hypertrophy in patients with essential hypertension. Echocardiography revealed significant reductions in wall thickness after 12 weeks of treatment.
Area of Science:
- Cardiology
- Hypertension Research
- Diagnostic Imaging
Background:
- Essential hypertension frequently leads to left ventricular hypertrophy (LVH).
- LVH can manifest as asymmetric septal hypertrophy (ASH) or symmetrical hypertrophy.
- The impact of antihypertensive treatment on established LVH requires further investigation.
Purpose of the Study:
- To assess the effect of antihypertensive therapy on left ventricular hypertrophy in patients with essential hypertension.
- To determine if blood pressure reduction can lead to regression of LVH.
Main Methods:
- Echocardiography was used to evaluate left ventricular wall thickness in 24 patients with essential hypertension.
- Patients received 12 weeks of antihypertensive treatment aimed at reducing supine blood pressure to 150/90 mmHg or below.
- Changes in left ventricular configuration and wall thickness were monitored.
Main Results:
- Initially, 14 of 24 patients had LVH, with 8 showing asymmetric septal hypertrophy (ASH) and 6 symmetrical hypertrophy.
- After 12 weeks of treatment, only 2 of the 8 patients with initial ASH continued to meet the criteria.
- Patients with symmetrical LVH also demonstrated significant reductions in septal and posterior wall thickness.
Conclusions:
- Antihypertensive therapy can lead to a regression of left ventricular hypertrophy.
- Reducing blood pressure effectively reverses cardiac structural changes associated with hypertension.
- Echocardiography is a valuable tool for monitoring treatment response in hypertensive patients with LVH.
Abstract:
1 Echocardiography showed 14 of 24 patients with essential hypertension to have hypertrophy of their left ventricular walls. In eight of these 14 patients the left ventricular configuration initially fulfilled the criteria for asymmetric septal hypertrophy (ASH) and six were symmetrically hypertrophied, the remaining ten being normal. 2 Following 12 weeks' treatment of hypertension with the object of reducing the supine BP to 150/90 mmHg or below, there was a reduction of wall thickness so that only two of the eight continued to show ASH. 3 The six patients with symmetrical left ventricular hypertrophy also showed a significant reduction in the thickness of the septum and the posterior wall. Those with normal echocardiograms did not change. 4 This reduction of wall thickness produced by antihypertensive therapy may represent regression of left ventricular hypertrophy.
