[Distribution, determinants and reference values of left ventricular parameters in the general population--results of the MONICA/KORA echocardiography studies].
For successful fighting against the burden of cardiovascular disease in the community a comprehensive knowledge about the prevalence and the impact of underlying risk factors is important. The present paper summarises some studies undertaken on more than 2000 persons from the MONICA/KORA-studies (parts of S1 and S3) where left ventricular mass (LVM) and other left ventricular parameters were determined by echocardiography. We especially investigated the associations of LVM with blood pressure and obesity. A special focus was on sex-specific factors in the determination of LVM and the influence of different indices of body size when normalising LVM. It could be shown that hypertension and obesity are major determinants of LV hypertrophy. Especially women with both hypertension and obesity on showed a high prevalence of concentric hypertrophy, significantly more than men. We also showed that the prevalence of LV hypertrophy in a representative sample of the general population (25 to 74 years) is 17.5 % for men, and 18.5 % for women. This underscores the need for primary and secondary prevention regarding the development of LV hypertrophy. Finally, our data in a selected group of normal subjects (reference sample) may be used for the development of reference values for left ventricular parameters in the general German population.
