Abstract
Prediction of ventricular arrhythmias and sud¬den cardiac death after myocardial infarction In order to stratificate the risk of arrhythmic events (AE) such as sudden cardiac death, vent¬ricular fibrillation, sustained vertricular tach¬ycardia in the first year after myocardial infarction, 62 patients were evaluated with echocardiography, Holter monitorisation and high resolution signal averaged electrocardiography (HI-RES ECG). Patients were divided into 2 subgroups according to presence or absence of AE [AE (+): 5 (%8), AE (-): 57 (%92)]. Patients with AE [(mean left ventricular ejection fraction (LVEF): % 48±13.5 showed 5 (%100) late potentials (LP), 1 (%20) malign VA and 3 (%60) LV dysfunction with LVEF < %40, while the other patients with AE (-) (LVEF % 55+9.7) had 28 (49%) LP (+), 2(%3.5) malign VA ve 7 (%I2) LVEF<%40 (p<0.05, p>0.05, p<0.01). During the 1 ' year follow-up, LP (+) patients (n=33) who had 6 (18%) LVEF<%40 and 3(%9) malign VA showed 5 (%15) sudden death, while LP (-) patients (n=29) who had 4 (13.8%) VEF<%40 but no malign VA, showed no sudden death (p>0.05, p>0.05, p<0.05). Patients with VA (n=14) who had 11(%78.5) LP (+) and 5J%35.7) LVEF<40 showed 4 (%28.5) sud¬den death in the first year after AMI, whereas pa¬tients without VA (n=48) who had 22 (%45.8) LP (+) and 5(%10) LVEF<%40 showed 1 (2%) sudden death (p<0.05, p<0.05, p<0.01). Patients with LVEF<%40 (n=10), who had 6 (%60) LP (+) and 1 (%10) malign VA before hospital discharge evolved 3 (%30) sudden death, whereas pa¬tients with LVEF>%40 (n=52) who had 27 (%51.9) LP (+) and 2 (%3.8) malign VA before hospital disc¬harge, showed 2 (%3.8) sudden death in the one year follow-up period (p>0.05, p>0.05, p<0.0I). In conclusion, in the risk stratification of arrhy¬thmic events after AMI, all of the three methods (ec¬hocardiography, Holter, HI-RES ECG) are useful where HI-RES ECG is more sensitive.
Özet
Akut miyokard infarktüsü (AMI) geçiren 62 olgu hastaneden çıkmadan önce ekokardiyogra.fi, ■ Holter monitor . ve sinyal ortalamak elektrokardiyografi (SOEKG) ile incelendi. Bir yıllık takip süresi içinde aritmi olayı (AO) (ani ölüm, ventriküler fibrilasyon, sürekli ventriküler taşikardi) yönünden değerlendirildi. ' AMI geçiren olgular, AO (+) [5 (%8)] ve AO (-) [57 (%92)] gruplara ayrıldı. AO (+) grubun [sol ventrikül ejeksiyon fraksiyonu (LVEF): % 48+13.5 mmHg] tümünde (% 100) geç potansiyel (LP) po¬zitifliği, I 'inde (%20) malign ventriküler aritmi (VA) 3 olguda (%60) LVEF 0.05, p 0.05, p>0.05, p %40 olan ve-27 olguda (%51.9) LP (+), 2 olguda (%3.8) malign VA tesbit edilen 52 ol¬gunun bir yıllık takibinde 2 tanesinde, (%3.8) ani ölüm gelişti (p>0.05, p>0.05, p<0.01). Sonuç olarak AMI sonrası malign VA ve ani ölüm riskinin belirlenmesinde en fazla SOEKG olmak üzere 3 yöntemin de (SOEKG, eko-kardiyogra.fi, Holter monitor) faydalı olabileceği ka¬naatine varıldı.
