[Distribution, determinants and reference values of left ventricular parameters in the general population--results of...

Area of Science:

• Cardiology
• Public Health
• Medical Imaging

Background:

• Cardiovascular disease poses a significant public health burden.
• Understanding the prevalence and risk factors of conditions like left ventricular hypertrophy (LVH) is crucial for effective community health strategies.
• Echocardiography plays a vital role in assessing cardiac structure and function.

Purpose of the Study:

• To investigate the associations between left ventricular mass (LVM) and risk factors like hypertension and obesity.
• To explore sex-specific determinants of LVM and the impact of body size indices on normalization.
• To determine the prevalence of LVH in a general population sample.

Main Methods:

• Analysis of data from over 2000 individuals in the MONICA/KORA studies (S1 and S3).
• Echocardiography used to measure left ventricular mass (LVM) and other left ventricular parameters.
• Statistical analysis focusing on associations with blood pressure, obesity, and sex-specific factors.

Main Results:

• Hypertension and obesity were identified as major determinants of left ventricular hypertrophy (LVH).
• Women with both hypertension and obesity exhibited a significantly higher prevalence of concentric hypertrophy compared to men.
• The prevalence of LVH in the general population (ages 25-74) was 17.5% for men and 18.5% for women.

Conclusions:

• Hypertension and obesity are significant risk factors for developing LVH.
• Sex-specific differences exist in the manifestation of LVH, particularly in women with comorbid hypertension and obesity.
• Findings emphasize the necessity of primary and secondary prevention programs for LVH and provide a basis for establishing German reference values.
