[Evaluation of the cardiovascular risk in hypertensive patients: left ventricular hypertrophy]

Area of Science:

• Cardiology
• Medical Imaging
• Hypertension Research

Background:

• Left ventricular hypertrophy (LVH) is linked to increased cardiovascular complications, especially in hypertensive individuals.
• Echocardiographic measurement of left ventricular mass offers a quantitative risk assessment, potentially integrating multiple cardiovascular risk factors.
• Current risk factor assessment is variable and challenging, prompting interest in integrated markers like LV mass.

Purpose of the Study:

• To evaluate the utility of echocardiographic left ventricular mass measurement as a risk marker in cardiovascular disease.
• To explore the potential of LV mass as a surrogate for traditional risk factors in hypertensive patients.
• To assess the feasibility and reproducibility of M-mode echocardiography for LV mass determination.

Main Methods:

• Utilized M-mode echocardiography to measure left ventricular mass.
• Assessed the feasibility of the technique in a general population (approximately 80% success rate).
• Evaluated the reproducibility of LV mass measurements, even among experienced sonographers.

Main Results:

• Echocardiographic LV mass measurement provides a risk assessment independent of classical factors.
• The technique's feasibility is limited to about 80% of the population.
• Reproducibility of LV mass measurements is not yet perfect, even with expert users.

Conclusions:

• While promising, echocardiographic LV mass measurement is not yet recommended for routine use due to technical limitations and the need for further validation.
• Monitoring LV mass regression during treatment could offer a shorter, more efficient alternative to traditional morbidity-mortality trials in hypertension.
• Further research is needed to confirm if LVH regression translates to reduced cardiovascular complications.
