Abstract

AIM: The objective of the present study was to describe clinical features and medium term follow-up of patients with myocardial infarction and normal coronary arteries. PATIENTS AND RESULTS: Between June 1994 and April 1996, 3120 coronary angiographies were performed in our clinic. During this period 15 patients (10 men, 5 women) with mean age of 46.8±8.7 years (34-63) with documented myocardial infarction and completely normal coronary arteries were identified. According to the ECG criteria there was no predilection for a specific location of MI (6 anterior MIs, 8 inferior MIs and 1 posterior). Thrombolytic therapy was performed in 2 patients. In 7 patients areas of localized hypo- or akinesia were shown on left ventricular cineangiography. The mean ejection fraction was 61.6±10 %. Most of them (11 patients, 73%) are cigarette smokers. During a mean follow-up period of 50.4±5.7 (44-66 months) no patient died and no patient suffered from angina pectoris or heart failure. CONCLUSION: Patients with acute MI and angiographically normal coronary arteries seem to have a favorable prognosis.

Özet

AMAÇ: Akut miyokart enfarktüsü geçirmiş ve koroner arterleri normal olan hastaların klinik özelliklerini ve orta süreli izleme bulgularını, araştırmak. HASTALAR VE BULGULAR: Haziran 1994 ile Nisan 1996 tarihleri arasında kliniğimiz koroner anjiografi laboratuarında yapılan 3120 koroner anjiografiden 15'inde (5 kadın, 10 erkek, 34-63 yaşları arası, ortalama 46.8±8.7) dokümante edilmiş miyokart enfarktüsü ve normal koroner arter görüldü. Mİ lokalizasyonu açısından bir yöne eğilim yoktu. (6 anterior, 8 inferior, I posterior). Trombolitik tedavi 2 hastaya uygulandı. Hastalarda ventrikülografik olarak ortalama ejeksiyon fraksiyonu %61.6±10 idi ve hastaların 7'sinde hipokinezi veya akinezi şeklinde duvar hareket bozukluğu görüldü. Hastaların çoğunluğunun (11 hasta, %73) sigara içtiği dikkati çekti. Hastalar 44-66 ay arasında ortalama 50.4±5.7 ay izlendi. İzleme süresi boyunca hastalarda ölüm, kalp yetmezliği veya angina pectoris görülmedi. SONUÇ: Sonuç olarak anjiografık olarak normal koroner arteri olan akut miyokart enfarktüsü geçirmiş hastaların prognozıınun oldukça iyi olduğunu söyleyebiliriz.
