Cardiovascular Morbidity And Mortality

Left ventricular hypertrophy is the main risk factor for development of cardiovascular morbidity and mortality in patients on hemodialysis. Left ventricular hypertrophy is found in 75% of the patients treated with hemodialysis. Risk factors for left ventricular hypertrophy in patients on hemodialysis include: blood flow through arterial-venous fistula, anemia, hypertension, increased extracellular fluid volume, oxidative stress, microinflammation, hyperhomocysteinemia, secondary hyperpara- thyroidism, and disturbed calcium and phosphate homeostasis. Left ventricular pressure overload leads to parallel placement of new sarcomeres and development of concentric hypertrophy of left ventricle. Left ventricular hypertrophy advances in two stages. In the stage of adaptation, left ventricular hypertrophy occurs as a response to increased tension stress of the left ventricular wall and its action is protective. When volume and pressure overload the left ventricle chronically and without control, adaptive hypertrophy becomes maladaptive hypertrophy of the left ventricle, where myocytes are lost, systolic function is deranged and heart insufficiency is developed. Left ventricular mass index-LVMi greater than 131 g/m2 in men and greater than 100 g/m2 in women, and relative wall thickness of the left ventricle above 0.45 indicate concentric hypertrophy of the left ventricle. Eccentric hypertrophy of the left ventricle is defined echocardiographically as LVMi above 131 g/m2 in men and greater than 100 g/m2 in women, with RWT ?0.45. Identification of patients with increased risk for development of left ventricular hypertrophy and application of appropriate therapy to attain target values of risk factors lead to regression of left ventricular hypertrophy, reduced cardiovascular morbidity and mortality rates and improved quality of life in patients treated with regular hemodialyses.

Purpose:The aim of this investigation was to assess the influence of an 8-month physical training period on left ventricular voltages identified by resting ECG in relation to changes in left ventricle mass in adolescent athletes.Methods:The study encompassed 28 adolescents aged 13 years (14 boys and 14 girls) from a sports secondary school. Clinical assessment was performed on all athletes before and after 8 months of physical training.Results:Sokolov-Lyon voltage index, Cornell voltage index, and maximum spatial QRS vector magnitude demonstrated statistically significant decline during the study period. The specific potential of the myocardium also significantly decreased during 8 months of training. The Sokolov-Lyon voltage criterion for left ventricular hypertrophy was fulfilled in 9 athletes (32.1%) at the beginning of the observation and only in 3 athletes (10.7%) at the end of the study. On the other hand, mean left ventricular mass and mean left ventricular mass index significantly increased after long-term training. No statistically significant correlations were identified between relative changes in left ventricular mass and QRS voltages.Conclusion:An early period of intensive physical training in young athletes is associated with a decrease in QRS amplitude and a relative voltage deficit over the left ventricle.

Aim. To study the distribution of cardiovascular risk factors, target organ damage, associated clinical conditions and to stratify the 10-year risk of arterial hypertension complications in menopausal females depending on presence of inappropriately high left ventricular mass. Methods. 107 females from city of Kazan aged 42-59 years entered the study, including 11 women with normal blood pressure, 16 patients with high normal blood pressure, and 80 patients with hypertension according to All-Russia scientific Society of Cardiologists classification (2010) with disease duration of 0-34 years. Mean age of patients with hypertension was 51.4±4.0 years. Patients with secondary hypertension were excluded from the study. All patients underwent a questionnaire survey, physical examination, biochemical blood test, ECG, echocardiography, and cervical extracranial vessel ultrasonography. Actual left ventricle mass was calculated according to R.B. Devereux et al. (1977) and was adjusted to the body surface area. Proper left ventricle mass was defined by G. Simone et al. (1998). Disproportion coefficient was calculated as a ratio of actual left ventricle mass to proper left ventricle mass. Left ventricle hypertrophy was diagnosed using the Sokolow-Lyon index and left ventricle mass index ≥ 110 g/m2 (Echo-signs of left ventricle hypertrophy). Results. In menopausal women, inappropriately high left ventricular mass was associated with significantly (р 0.05, Fisher exact test) higher frequency of obesity, especially its abdominal type, as well as target organ damage, including Echo-signs of left ventricle hypertrophy, very high added 10-year risk of developing arterial hypertension complications. It was also associated with significantly (р 0.05, the U-criterion) higher mean values of waist circumference, waist to hip circumference ratio, body mass index, total number of damaged target organs and 10-year risk for developing arterial hypertension complications. Conclusion. Distinguishing the patients with inappropriately high left ventricular mass among menopausal women is important for planning the measures to prevent cardiovascular events.
