Some Predictors of Heart Rhythm Disturbances in Myocardial Infarction

To identify some predictors of complex ventricular arrhythmias (CVA) on 10-12 day of QMI. In 31 men with QMI, CVA were studied on Holter monitoring, Sympathoadrenal system (SAS) - by daily excretion with urine of epinephrine (E), norepinephrine (NE) and dofamin (D). Echocardiography was carried out according to ASE recommendations. Group (G) I included 15 patients with CVA (Lown-Wolf), GII - without CVA. CVA was revealed more frequently in anterior MI (93% and 57%), (p<0,05), left ventricle (LV) aneurism (73% and 19%), (p<0,05).Excretion of E in GI was 0,0118 and in GII 0,0074mg/d, (p<0,001), differences in excretion NE and D were n.s. LV EDV and edvi in GI were 152,4ml and 80,3 ml/m2, in GII - 130,4 and 68,4, (p<0,05), values of ESV and esvi were 85,2 and 45,1; 63,1ml and 33,1 ml/m2 in GI and GII respectively, (p<0,05). LVEF in GI and GII were 44,7 and 52,1%, (p<0,05). In QMI reliability of CVA identification was higher in anterior MI, SAS hyperactivation, LV aneurism, increases in LV EDV, ESV and decrease in LVEF.
