[Effect of postinfarct left ventricular dysfunction on late occurrence of mitral regurgitation--two year experience].
The aim of this study was to evaluate factors that might influence on the occurrence of mitral regurgitation (MR) in patients (pts) following myocardial infarction (MI) after fibrinolysis--two year experience. The study group comprised 118 pts: 40 women and 78 men (mean age: 58 +/- 9 years) following MI, who underwent Doppler echocardiography which revealed no MR 3 weeks after the MI. The second echocardiographic examination was performed after 2 years. We evaluated the following parameters: presence and stage of MR, left ventricular end-diastolic diameter (LVDD), left atrial diameter (LA), end-diastolic volume (EDV), wall motion score index (WMSI), asynergic area (AA) and ejection fraction (EF). Results after 2 years were as follows: 43 pts (36%) presented without MR, 45 (38%) MR I degree, 27 (23%) MR II degree, 3 (3%) MR III degree. Echocardiographic parameter comparison after 2 years demonstrated the following changes: LVDD increase from 5.0 +/- 0.5 cm to 5.3 +/- 4.6 cm (p < 0.005), LA increase from 3.7 +/- 0.4 cm to 4.3 +/- 0.4 cm (p < 0.00001), EDV increase from 130 +/- 29 ml to 147 +/- 39 ml (p < 0.005), WMSI increase from 1.37 +/- 0.23 to 1.45 +/- 0.21 (p < 0.05), AA increase from 23.5 +/- 10.1% to 27.8 +/- 7.9% (p < 0.005) and significant EF decrease 50.4 +/- 7.9% to 46.9 +/- 7.1% (p < 0.005). These results demonstrate that the occurrence of MR 2 years after the MI is caused by left ventricular remodelling, as well as segmental and global function deterioration.
