1Cardiovascular Department of Internal Medicine, the Second Affiliated Hospital of Dalian Medical University, PR China.
Insights
Left ventricular geometric alterations in hypertensive patients correlate with extracardiac organ damage. Echocardiographic patterns help stratify risk and guide intensive treatment for better hypertension management.
Area of Science:
- Cardiology
- Hypertension Research
- Medical Imaging
Background:
- Essential hypertension is a major risk factor for cardiovascular and target organ damage.
- Left ventricular geometry alterations are common in hypertension and linked to adverse outcomes.
- Understanding the relationship between cardiac structure and extracardiac damage is crucial for risk stratification.
Purpose of the Study:
- To investigate the association between left ventricular geometric patterns and extracardiac target organ damage in hypertensive individuals.
- To determine if echocardiographic parameters can predict organ damage in patients with essential hypertension.
Main Methods:
- Retrospective analysis of 298 essential hypertension patients.
- Echocardiography used to calculate left ventricular mass index (LVMI) and relative wall thickness (RWT).
- Patients categorized into four groups based on left ventricular geometric patterns.
Main Results:
- Each of the four left ventricular geometric patterns was linked to varying degrees of extracardiac organ damage.
- LVMI and RWT showed significant correlations with retinal changes and elevated serum creatinine, respectively.
- Left ventricular geometric alterations were associated with increased extracardiac target organ damage.
Conclusions:
- Echocardiographic classification of left ventricular geometry effectively stratifies hypertensive patients by risk.
- This classification may inform decisions regarding the need for intensive treatment in hypertension.
- Left ventricular geometry serves as a valuable indicator for predicting target organ damage in hypertensive patients.
Abstract:
To study the relation between left ventricular geometric alteration and extracardiac target organ damage in hypertensive patients. A retrospective study of 298 patients with essential hypertension was performed. Left ventricular mass index (LVMI) and relative wall thickness (RWT) were calculated using echocardiographic data. Patients were divided into four groups based on their left ventricular geometric pattern as determined using LVMI and RWT. Each of the four left ventricular geometric patterns was associated with a different degree of extracardiac organ damage. In multivariate analysis, LVMI and RWT showed strong, significant correlation to retinal changes and increases in serum creatinine levels, respectively. Alteration of left ventricular geometry resulted in an increase in the degree of extracardiac target organ damage. Echocardiographic classification of left ventricular geometry can further stratify hypertensive patients according to risk, and possibly according to the indications for intensive treatment.
