Akut iskemik inmeli hastalarda miyokard fonksiyonunun doku Doppler miyokardiyal performans indeksi ile değerlendirilmesi

Amaç: Bu çalışmanın amacı, akut iskemik inmeli hastalarda National Institutes of Health Stroke Ölçeği (NIHSS) ile doku Doppler miyokard performans indeksi ile değerlendirilen miyokard fonksiyonları arasındaki ilişkiyi araştırmaktır.Gereç ve Yöntem: Çalışmaya akut iskemik inme geçiren 128 hasta (erkek,55; kadın, 73; yaş, 68 ± 19) alındı. 20 hasta çalışmadan çıkarıldı. NIHSS skoruna göre hastalar iki gruba ayrıldı (Grup 1, NIHSS skor <16; Grup 2, NIHSS skoru ≥ 16). Bütün hastalardan demografik, klinik ve laboratuvar verileri toplandı. Hastaların kardiyak fonksiyonları, nöroloji yoğun bakım ünitesine yatırıldıktan sonraki 48 saat içerisinde transtorasik ekokardiyografi değerlendirildi.Bulgular: Hastaların demografik özellikleri açısından gruplar arasında anlamlı farklılık saptanmadı. Doku Doppler miyokard performans indeksi, Grup 2 hastalarında, Grup 1 hastalarına göre anlamlı derecede daha yüksek bulundu (0.62±0.28 ile 0.46±0.16).Sonuç: Yapmış olduğumuz bu çalışmada, akut iskemik inme ile yatan hastalarda, inme şiddeti ile doku doper miyokard performans indeksi arasında bir ilişki olduğu sonucuna varılabilir. Doku Doppler MPİ, LV EF’dan farklı olarak, global miyokardiyal disfonksiyonunun bir göstergesidir. Doku Doppler MPİ, hem sistolik, hem de diyastolik zaman intervallerini içermekte olup, global kardiyak disfonksiyonu değerlendirir.

Assessment of myocardial function by tissue Doppler imaging myocardial performance index in patients with acute ischemic stroke

Purpose: The aim of this study is to investigate the relationship between myocardial function assessed by tissue Doppler imaging myocardial performance index (TDI-MPI) and National Institutes of Health Stroke Scale (NIHSS) score in patients with acute ischemic stroke. Materials and Methods: The study comprised 128 patients (males, 55; females, 73; 68 ± 19 years) with acute ischemic stroke. 20 patients were excluded. Patients were divided into two groups based on the calculated NIHSS score (Group 1, NIHSS score < 16; Group 2, NIHSS score ≥ 16). Demographic, clinical, and laboratory data for all patients were collected. Cardiac function was evaluated by transthorasic echocardiography within 48 hours of admission to the neurology care unit.Results: There were no significant differences among demographic parameters of patients. Tissue Doppler myocardial performance index was significantly higher in Group 2 patients than in Group 1 patients (0.62±0.28 vs 0.46±0.16).Conclusion: Our results suggest that TDI-MPI is associated with stroke severity on admission in patients with acute ischemic stroke. TDI-MPI is an indicator of global myocardial dysfunction with a different from LVEF. TDI-MPI, which includes both systolic and diastolic time intervals to assess the global cardiac dysfunction.
