“…An increasing number of studies has reported the use of a combined index integrating systolic and diastolic LV function, the overall myocardial performance index (MPI)[9], for predicting short-term adverse outcome in AMI [10-14]. However, some included high-risk patients with multiple myocardial infarction [10,13] and previous history of CHF [13] or with non-ST elevation [10-13], while others studied only anteroseptal AMI [14], that could affect their results.…”

“…However, some included high-risk patients with multiple myocardial infarction [10,13] and previous history of CHF [13] or with non-ST elevation [10-13], while others studied only anteroseptal AMI [14], that could affect their results. Moreover, some authors [11,13,14] considered diverse in-hospital complications besides CHF (recurrent angina, reinfarction, death, arrhythmias, heart block, cardiac rupture and pericardial effusion), not always solely related to the extend of LV dysfunction in the acute phase of AMI. These factors may justify some controversy about the short-term independent prognostic significance of MPI in AMI patients, defended by some [10,11,14] but questioned by others [12,13].…”

BackgroundLeft ventricular ejection fraction (LVEF) has been considered a major determinant of early outcome in acute myocardial infarction (AMI). Myocardial performance index (MPI) has been associated to early evolution in AMI in a heterogeneous population, including non ST-elevation or previous AMI. Left atrial volume has been related with late evolution after AMI. We evaluated the independent role of clinical and echocardiographic variables including LVEF, MPI and left atrial volume in predicting early in-hospital congestive heart failure (CHF) specifically in patients with a first isolated ST-elevation AMI.MethodsEchocardiography was performed within 30 hours of chest pain in 95 patients with a first ST-elevation AMI followed during the first week of hospitalization. Several clinical and echocardiographic variables were analyzed. CHF was defined as Killip class ≥ II. Multivariate regression analysis was used to select independent predictor of in-hospital CHF.ResultsEarly in-hospital CHF occurred in 29 (31%) of patients. LVEF ≤ 0.45 was the single independent and highly significant predictor of early CHF among other clinical and echocardiographic variables (odds ratio 17.0; [95% CI 4.1 - 70.8]; p < 0.0001). MPI alone could not predict CHF in first ST-elevation AMI patients. Left atrial volume was not associated with early CHF in such patients.ConclusionFor patients with first, isolated ST-elevation AMI, LVEF assessed by echocardiography still constitutes a strong and accurate independent predictor of early in-hospital CHF, superior to isolated MPI and left atrial volume in this particular subset of patients.

Acute myocardial infarction (AMI) is still among the major causes of mortality and morbidity especially in the developed countries. There are two treatment modalities: primary percutaneous coronary intervention (PPCI) and thrombolytic therapy (TT). The Tei Index (Myocardial Performance Index) has become a valuable echocardiograhic index for assessment of global systolic and diastolic function. TDI Tei index correlates with pulsed wave measurements. 1,2 Tei index provides prognostic information in patients with dilated cardiomyopathy, cardiac amyloidosis, acute myocardial infarction congenital heart disease and primary pulmonary hypertension. [3][4][5][6][7][8][9][10][11] Increased Tei index is a strong predictor of mortality and morbidity after acute myocardial infarction. [9][10][11] Duan Y et al. demonstrated that RV TDI Tei index correlated well with the Tei index obtained by pulsed Doppler in fetuses. This demonstrated that RV TDI Tei index is a simple and valuable method of assessing RV global function even in seldom evaluated subjects such as fetuses. 12 Even if the right ventrincle has not faced ischemia it may be affected by left ventricle ischemia. In the GISSI-3 Echo Substudy, RV function deteriorated in acute MI patients and RV function recovery over time ORIGINAL RESEARCH

“…Myocardial performance index (MPI) was calculated with the Tei index formula (IVRT + IVCT/ET). 22 Tissue Doppler imaging (TDI) was obtained from the apical four-chamber image with the pulse wave Doppler sample volume traced at the mitral-lateral annulus. Peak systolic velocity (Sm), peak early (Em) and peak late (Am) diastolic myocardial annular velocities, ET, IVRT and IVCT were measured.…”

Aims: We aimed to evaluate asymmetric dimethylarginine levels in young patients with Type 1 diabetes mellitus according to diabetes duration and to examine the relationship between these levels and measures of atherosclerosis and myocardial function. Materials and methods: In total, 83 patients (8.5-22 years) with Type 1 diabetes mellitus were stratified by diabetes duration: 12-60 months (Group 1, n = 27), >60-120 months (Group 2, n = 29) and >120 months (Group 3, n = 27). Asymmetric dimethylarginine levels were assessed. Carotid intima-media thickness was measured. Myocardial function was assessed by M-mode, conventional Doppler and tissue Doppler echocardiography. Results: Asymmetric dimethylarginine level was significantly higher in Group 1, while carotid intima-media thickness was significantly greater in Group 3 (p < 0.05). Tissue Doppler echocardiography showed the ratio of peak early to peak late diastolic myocardial annular velocity decreased significantly in Groups 2 and 3 with a negative correlation with duration (r: −0.310, p = 0.004) and HBA1c levels (r = −0.391, p < 0.001). Myocardial performance index in all groups and isovolumic relaxation time in Group 3 increased significantly. Asymmetric dimethylarginine levels were negatively correlated with carotid intima-media thickness and isovolumic relaxation time (p < 0.05). Conclusion: In contrast to adult diabetics, asymmetric dimethylarginine concentration decreases as diabetes duration increases in young Type 1 diabetic patients and is associated with worsening measures of cardiovascular risk and poorer diastolic function.
