The myocardial performance index (MPI) is used for global systolic-diastolic left ventricular function and prognosis assessment in patients with heart disease, allowing assessment of the patient‘s current condition and disease development follow-up. The classic method of calculation is pulsed Doppler echocardiography. The aim of the study was to evaluate the correlation of myocardial performance index with established left ventricular systolic and diastolic function indices and to determine cut-off values of the myocardial performance index in M-mode color tissue Doppler echocardiography through the aortic and mitral valves predicting abnormal myocardial performance index by pulsed Doppler echocardiography. One hundred and fi ve subjects were studied, including 30 healthy controls, 45 hypertensive patients, and 30 patients with CHD. MPI was calculated using pulsed Doppler (MPIPW) and M-mode color tissue Doppler echocardiography through the aortic (MPIAO1 and MPIAO2) and mitral (MPIMV) valves. In all patients, the myocardial performance index showed a low to moderatenegative correlation with the left ventricular ejection fraction, and the correlation with the diastolic function indices was moderate to high. In healthy persons, the correlations were not signifi cant in almost all comparisons. The MPIAO1, MPIAO2,and MPIMV values predicting abnormal MPI by pulsed Doppler (MPIPW ≥ 0.50) are MPIAO1 ≥ 0.578, MPIAO2 ≥ 0.446, and MPIMV ≥ 0.552. The cut-off values of MPI by M-mode color tissue Doppler echocardiography through the aortic and mitral valve obtained can be used for global left ventricular function assessment in patients with heart disease. Further studies, on a larger number of patients, are necessary to estimate the predictive value of the parameters established.

Myocardial Performance

Latar belakang.Bayi kurang bulan merupakan masalah di negara maju maupun negara berkembang. Pada bayi kurang bulan tahanan vaskular paru masih tinggi, sehingga tekanan di ventrikel kanan tinggi. Pengukuran fungsi ventrikel kanan sulit dilakukan dengan ekokardiografi standar karena bentuk geometri ventrikel kanan yang berbentuk “bulan sabit” dan trabekuler yang kasar.Myocardial performance index tissue doppler imaging (MPI-TDI) adalah cara pengukuran fungsi ventrikel kanan yang baru dikembangkan, merupakan penilaian fungsi ventrikel kanan pada fetus, anak, dan dewasa dengan berbagai penyakit jantung. Tujuan.Menilai apakah MPI-TDI pada bayi cukup bulan lebih tinggi dibandingkan dengan kurang bulan dan bagaimana korelasi antara MPI-TDI dan usia kehamilan.Metode.Penelitian dilakukan terhadap 36 bayi (17 bayi kurang bulan dan 19 bayi cukup bulan), berusia kehamilan 33–42 minggu, yang menjalani pemeriksaan MPI-TDI dengan menggunakan ekokardiografi, di Instalasi Pelayanan Jantung RS Dr. Hasan Sadikin periode Juli–Oktober 2010 dengan rancangan potong lintang. Analisis statistik yang digunakan adalah one wayANOVA untuk menilai perbedaan MPI-TDI bayi cukup bulan dan kurang bulan serta uji korelasi rankSpearman untuk menilai korelasi antara MPI-TDI dan usia kehamilan dengan kemaknaan hasil uji bila didapatkan p<0,05.Hasil.Didapatkan rerata MPI-TDI untuk bayi usia kehamilan <34 minggu adalah 0,31 (0,03), bayi usia kehamilan 34–36 minggu 0,32 (0,03) dan bayi usia kehamilan >37 minggu adalah 0,30 (0,03) (p=0,03). Nilai korelasi antara MPI-TDI dan usia kehamilan adalah (0,24) dengan nilai p=0,378. Kesimpulan.Didapatkan perbedaan MPI-TDI ventrikel kanan antara bayi kurang bulan dan cukup bulan. Tidak ada korelasi antara MPI TDI dan usia kehamilan.
