Abstract :In this study, the kinetic, structural and functional changes of the ventriculus in dogs with myocardial infarction introduced experimentally were examined using M-Mode and two dimensional insert ignore into journalissuearticles values(2-D); echocardiography. 21 healthy, mixed-breed dogs of both genders insert ignore into journalissuearticles values(16 females and 5 males); and of various ages were used in this study. Different coronary arteries were ligated in each dog with silk sutures and the dogs were grouped accordingly: left distalis descending coronary artery insert ignore into journalissuearticles values(Group I, n=7);, right distalis descending coronary artery insert ignore into journalissuearticles values(Group II, n=7); and both left and right distalis decending coronary artery insert ignore into journalissuearticles values(Group III, n=7);. All the dogs were examined using echocardiography prior to the study. After the coronary arteries were ligated, this was repeated at 2, 4, 8 and 12-hour intervals for seven days. Wall motion abnormalites were observed in areas of infarction insert ignore into journalissuearticles values(left ventricle posterior wall = LVPW); in addition to irregularities in mitral valvule insert ignore into journalissuearticles values(MV); movements 2 hours after coronary ligation in Group I Increases were observed in the left ventricle insert ignore into journalissuearticles values(LV); end-systolic diameter insert ignore into journalissuearticles values(EDS); and end-diastolic diameter insert ignore into journalissuearticles values(EDD);, circumference insert ignore into journalissuearticles values(C); and area insert ignore into journalissuearticles values(A);; and also int he right ventricle insert ignore into journalissuearticles values(RV); EDS and RVEDD, RVC, RVA, RV systolic volumes insert ignore into journalissuearticles values(SV); and diastolic volumes insert ignore into journalissuearticles values(DV); in Group I, whereas the LV shortening fraction insert ignore into journalissuearticles values(SF);, RVSF and ejection fraction insert ignore into journalissuearticles values(EF); insert ignore into journalissuearticles values(p
