📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: The objectives of the study were to assess myocardial systolic and diastolic functions by myocardial performance index (MPI) and its relationship with E – wave deceleration time (DT) in early phase of acute Q-wave myocardial infarction (MI).Methods: We performed nongeometric Doppler-derived echocardiography to assess combined systolic and diastolic functions using myocardial performance index in 50 patients with acute Q-wave MI at early phase of events, (25 pts with anterior MI and 25 pts with inferior MI).
📊
Key Findings & Data:The index is defined as the sum of the isovolumic contraction and isovolumic relaxation times divided by ventricular ejection time and was obtained by Doppler measurement from the diastolic mitral inflow and left ventricular outflow velocity-time intervals.Results: As a result, the index was 0.54±0.1 in all patients with MI.
💡
Conclusion & Impact:We also estimated the higher MPI and DT values in anterior than inferior MI (MPI: 0.61±0.07 vs., 0.46±0.06, p

Abstract

Objective: The objectives of the study were to assess myocardial systolic and diastolic functions by myocardial performance index (MPI) and its relationship with E – wave deceleration time (DT) in early phase of acute Q-wave myocardial infarction (MI).Methods: We performed nongeometric Doppler-derived echocardiography to assess combined systolic and diastolic functions using myocardial performance index in 50 patients with acute Q-wave MI at early phase of events, (25 pts with anterior MI and 25 pts with inferior MI). The index is defined as the sum of the isovolumic contraction and isovolumic relaxation times divided by ventricular ejection time and was obtained by Doppler measurement from the diastolic mitral inflow and left ventricular outflow velocity-time intervals.Results: As a result, the index was 0.54±0.1 in all patients with MI. We also estimated the higher MPI and DT values in anterior than inferior MI (MPI: 0.61±0.07 vs., 0.46±0.06, p

Özet

Amaç: Bu çalışmada akut Q-dalgalı miyokard infarktüsünün (Mİ) erken döneminde sol ventrikül sistolik ve diyastolik fonksiyonlarının miyokard performans indeksi (MPİ) ile değerlendirilmesi ve elde edilen değerin mitral E dalgası deselerasyon zamanı (DT) ile ilişkisinin ortaya konulması amaçlandı.Yöntem: Çalışmamıza Q-dalgalı Mİ tanısı ile koroner yoğun bakıma yatırılan olgulardan 25 anteriyor (yaş ort. 63±11 yıl), 25 inferiyor (yaş ort. 62±7l yıl ) olmak üzere toplam 50 olgu dahil edildi. Olguların 40’ı erkek (%80), 10’u kadın (%20) idi. Pulsed Doppler (PWD) ekokardiyografi ile ölçülen kalbin izovolümik gevşeme zamanı (İVGZ) ile izovolümik kasılma zamanının (İVKZ) toplamını, ejeksiyon zamanına bölünmesi ile MPİ değeri hesaplandı. Aynı zamanda mitral E dalgası DT ölçümü yapıldı.Bulgular: Anteriyor Mİ’lı olgularda MPİ ve DT inferiyor Mİ’lı olgulara göre daha yüksek bulundu (sırasıyla; MPİ: 0.61±0.07’e karşın 0.46±0.06, p
