title: [THE FEATURES OF STRUCTURE-FUNCTIONAL HEART CONDITION IN OLDER PATIENTS WITH UNSTABLE ANGINA AND LEFT BUNDLE BRANCH BLOCK].
abstract: The structural and functional parameters of echocardiography in 56 older patients with UA and LBBB were analyzed in comparison with these parameters in 186 patients with UA without LBBB. The median age of patients with UA and LBBB was 75 (67-81) years, without LBBB - 74 (65-80) years. The procedure was carried out in the first day of hospitalization in cardiology department on the UA. LBBB in patients with unstable angina is associated with remodeling of the heart with an increase the diameter of the aorta, the LVID (s) and (d), thickening of the IST and PWT and increasing the RWT, as well as a decrease of LP and RV cavities. We revealed the signs of left ventricular dysfunction without evidence valvular obstruction in the patients with UA and LBBB. The hemodynamic of patients with UA and LBBB was characterized by large LV DV and SV, as well as by decrease FS, FJ, MFS and gradients MV, AV, PV, and TV than at UA without LBBB. The echocardiographic symptoms of diastolic dysfunction with delayed relaxation were found in patients with UA and LBBB. The mitral regurgitation occurred more frequently in 2,4 times more in patients with UA without LBBB.
