[Diastolic function of the left ventricle in elderly patients with ischemic heart disease before and after the coronary shunting operation].
In order to assess the effect of coronary shunting (CS) on the diastolic function of the left ventricle (DFLV) in sick people of elderly and old age with ischemic heart disease stress-Doppler-echocardiogram was performed on 45 men at the age of 65 to 75 years before and after CS. The patients were formed into two groups on the basis of preoperative study of DFLV. Group I consisted of patients who had no myocardial infarction (MI) or who have had small-focal MI, parameters of transmitral blood flow in rest corresponded to impaired diastolic function on the "disturbed relaxation" type. Group II consisted of patients who have had transmural (large-focal) MI and whose DFLVcorresponded to the "pseudonormal blood flow" type (by S. Appleton). Analysis of indices of transmitral blood flowin rest before and after the operation showed its normalizing effect on DFLV in Group I. DFLV parameters in Group II demonstrated positive effect of the operation and were most pronounced when parameters of transmitral blood flow in stress were compared before and after CS. Thus, surgical revascularization of myocardium facilitates improvement of DFLV which can in its turn serve as an additional criterion of assessment of adequacy of CHD surgical treatment of sick people of elderly and old age with post infarction cardio sclerosis of various degree of manifestation.
