Determinants of left ventricular hypertrophy in arterial hypertension
1Governmental Hospital, GDR, Berlin.
Insights
Left ventricular hypertrophy (LVH) is a multifactorial process. Key predictors include male sex, longer hypertension history, higher blood pressure, and lipid issues, highlighting the need for comprehensive management.
Area of Science:
- Cardiology
- Hypertension Research
- Echocardiography
Background:
- Left ventricular hypertrophy (LVH) is a significant indicator of cardiovascular risk.
- Understanding the factors contributing to LVH development is crucial for effective prevention and treatment strategies.
Purpose of the Study:
- To identify clinical and echocardiographic predictors of developing left ventricular hypertrophy (LVH) in hypertensive patients over a long-term follow-up.
- To analyze the association between baseline parameters and the incidence of LVH.
Main Methods:
- A longitudinal study monitored 593 hypertensive and 156 normotensive individuals for 2-7 years.
- Echocardiographic measurements assessed left ventricular hypertrophy (LVH) (wall thickness ≥12 mm).
- Multivariate analysis identified factors associated with incident LVH.
Main Results:
- 49% of hypertensive patients developed echocardiographic signs of LVH, compared to 5.1% of normotensive individuals.
- Predictors of LVH included male sex, prolonged hypertension history, higher diastolic blood pressure, lipid metabolism disturbances, chest pain, and suboptimal antihypertensive treatment.
- LVH development was confirmed as a multifactorial process.
Conclusions:
- Left ventricular hypertrophy (LVH) development is influenced by a combination of patient characteristics and disease-related factors.
- Early identification and management of risk factors are essential for preventing LVH in hypertensive patients.
- The findings underscore the complex etiology of LVH.
Abstract:
A long term study (2-7 years, mean 3.6 years) monitoring 112 clinical and echocardiographic pattern in 593 hypertensives and 156 normotensives was performed in order to find associations to left ventricular hypertrophy (LVH) developing later. 49% of the hypertensives developed echocardiographic signs of LVH (wall thickness of 12 mm and more), in contrast to 5.1% of normotensive persons. Multivariate analysis revealed the following parameters examined at entry were associated with LVH on follow-up: male sex, prolonged hypertensive history, higher diastolic blood pressure, frequent lipid-metabolism disturbances, uncharacteristic chest pain and less effective antihypertensive treatment. Thus, LVH development can be regarded as a multifactorial process.
