Structural-and-functional changes in the heart in patients with associated arterial hypertension before endoprosthetic surgery of large joints

Osteoarthrosis incidence among subjects above 65 is 60-70 %, and arterial hypertension in the same age-related group occurs in 50 % of the subjects. But the severity of arterial hypertension is determined not only by the degree of arterial pressure increase. Early diagnostics of disordering the structure and function of target organs, and, first of all, those of the heart is one of the important moments. 50 patients at the age above 50 with the knee and the hip osteoarthrosis have been examined. All of them had associated arterial hypertension of IIIII stage. The patients were divided into groups depending on their age. ECG- and EchoCG-examination was performed in all of them. Left vetricular remodeling and hypertrophy progressing with age were observed in 82 % of cases. The higher values of wall thickness, myocardium mass, and myocardium mass index of the left ventricle, as well as the decreased values of ejection fraction and fractional shortening were observed in patients with the heart geometry changed in comparison with the patients with the heart normal geometry. High percentage of revealing the diastolic function disorder of both the left and the right ventricles was observed in all the groups.
