[Left ventricular function in patients with arterial hypertension and myocardial hypertrophy based on the data of
Insights
Hypertension can cause early subclinical left ventricular dysfunction, affecting cardiac energy and function, even when standard tests appear normal. This dysfunction involves energetic efficacy, diastolic function, and myocardial asynchronism in hypertensive patients.
Area of Science:
- Cardiology
- Hypertension Research
- Clinical Echocardiography
Background:
- Hypertension is a major risk factor for cardiovascular disease.
- Left ventricular hypertrophy (LVH) is a common complication of hypertension.
- Early detection of left ventricular dysfunction is crucial for managing hypertensive heart disease.
Purpose of the Study:
- To define early subclinical signs of left ventricular dysfunction in hypertensive patients with LVH.
- To investigate cardiac cycle energetic efficacy, diastolic function, and myocardial asynchronism.
- To identify dysfunction not detected by standard two-image analysis.
Main Methods:
- Study included 39 hypertensive subjects with clinical echocardiographic evidence of LVH.
- Coronary angiography and transvenous multiple-phase left ventriculography were performed.
- Analysis focused on energetic efficacy, diastolic function, and myocardial asynchronism.
Main Results:
- Early subclinical left ventricular dysfunction was identified in hypertensive patients.
- Dysfunction was characterized by impaired energetic efficacy of the cardiac cycle.
- Abnormalities in diastolic function and myocardial asynchronism were observed.
- These signs were present even when standard two-image analysis showed normal values.
Conclusions:
- Subclinical left ventricular dysfunction occurs early in hypertensive patients with LVH.
- Advanced echocardiographic techniques can detect dysfunction missed by standard analysis.
- Monitoring cardiac energetic efficacy, diastolic function, and asynchronism is vital in hypertension management.
Abstract:
The study included 39 hypertensive subjects with clinical echocardiographic evidence of left ventricular hypertrophy. All the patients were subjected to coronary angiography and transvenous multiple-phase left ventriculography. Early subclinical signs of left ventricular dysfunction in hypertensive patients have been defined. They concern energetic efficacy of the cardiac cycle, left ventricular diastolic function, myocardial asynchronism. It is noted that the above dysfunction was recorded in cases where standard two-image analysis provides normal values.
