The aim of this study was to investigate if there was an association between infarct size (IS) measured by cardiac magnetic resonance (CMR) and echocardiographic global longitudinal strain (GLS) in the early stage of acute myocardial infarction in patients with preserved left ventricular ejection fraction (LVEF). Patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were assessed with CMR and transthoracic echocardiogram within 1 week of hospital admission. Two-dimensional speckle tracking was performed using a semi-automatic algorithm (EchoPac, GE Healthcare). Longitudinal strain curves were generated in a 17-segment model covering the entire left ventricular myocardium. GLS was calculated automatically. LVEF was measured by auto-LVEF in EchoPac. IS was measured by late gadolinium enhancement CMR in short-axis views covering the left ventricle. The study population consisted of 49 patients (age 60.4 ± 9.7 years; 92% male). The study population had preserved echocardiographic LVEF with a mean of 45.8 ± 8.7%. For each percent increase of IS, we found an impairment in GLS by 1.59% (95% CI 0.57–2.61), P = 0.02, after adjustment for sex, age and LVEF. No significant association between IS and echocardiographic LVEF was found: −0.25 (95% CI: −0.61 to 0.11), P = 0.51. At the segmental level, the strongest association between IS and longitudinal strain was found in the apical part of the LV: impairment of 1.69% (95% CI: 1.14–2.23), P < 0.001, for each percent increase in IS. In conclusion, GLS was significantly associated with IS in the early stage of acute myocardial infarction in patients with preserved LVEF, and this association was strongest in the apical part of the LV. No association between IS and LVEF was found.

Abstract Background Depression of left ventricular function is common phenomenon after acute myocardial infarction and it's often associated with poor prognosis. However, substantial portion of patients with acute myocardial infarction had normal left ventricular function by assessment of left ventricular ejection fraction. Purpose In this study, we examined role of left ventricular global longitudinal strain assessment in patients who had normal ejection fraction after acute myocardial infarction. Methods We choose patients with acute myocardial infarction who were successfully treated with primary percutaneous coronary intervention (PCI). All of those patients had normal ejection fraction (EF≥55%) in routine echocardiographic examination within 3 days after acute myocardial infarction. Two dimensional speckle tracking echocardiography was used to assess left ventricular global longitudinal strain. Based on existence of newly onset clinical signs (pulmonary edema, lung crackles, peripherial edema etc.) of heart failure patients divided into case and control group. Patients who had other etiology or previous heart failure were excluded. Results A total of 153 patients with AMI were selected and newly onset heart failure is occurred in 20 patients. Left ventricular global strain was significantly different between patients with clinical heart failure and patients without clinical heart failure (−11.1±1.85% vs. −16.6±3.38%, p&lt;0.001). After adjustment of possible predictors of impaired left ventricular function such as, age, gender, hypertension, diabetes, previous coronary artery disease, cardiac troponin, mitral inflow EA ratio, deceleration time, left ventricular end diastolic volume, ejection fraction, mitral annulus EE' ratio and wall motion score index, global longitudinal strain was independent predictor of clinical heart failure (odds ratio 1.79, 95% CI 1.22–2.65, p=0.003). Adding global longitudinal strain into above mentioned predictors of clinical heart failure after acute myocardial infarction is associated with significantly increased c-statistic (0.93, 95% CI 0.87–0.99 vs. 0.97, 95% CI 0.94–0.99, p&lt;0.001). Conclusion Left ventricular global longitudinal strain is independently associated with clinical heart failure in patients with preserved ejection fraction after acute myocardial infarction. Adding global longitudinal strain parameter into screening model may increase rate of precise determination of clinical heart failure after acute myocardial infarction.

Objective    The purpose of this study was to investigate the association between global longitudinal strain (GLS) and plasma NT-proBNP for predicting left ventricular (LV) performance in asymptomatic patients after acute myocardial infarction (AMI).Material and methods    We prospectively included patients with diagnosis of AMI without clinical signs and symptoms of heart failure (HF) and followed these patients for 6 mos. Baseline echocardiography was performed at admission, and follow-up echocardiography was performed after 6 mos. A normal GLS was defined as having an absolute value of ≥16 %. According to the baseline GLS, participants were divided into two groups and compared. In all participants, blood samples of plasma NT-proBNP were obtained at admission, before discharge, and 6 mo after discharge.Results    The study population was consisted of 98 participants, of which 80 (81.6 %) were males, and the mean age was 56.0±9.3 years. Baseline echocardiography showed that most of the participants (60, 61.2 %) had abnormal GLS<16 %, whereas 38 (38.8 %) participants had normal or borderline GLS ≥16 %. Compared with the normal GLS group, participants with abnormal GLS had higher GRACE score, higher troponin I concentration, lower systolic blood pressure, lower mean LV ejection fraction, and decreased LV diastolic function. At 6‑mo follow-up, only LV systolic function remained significantly different between the two groups. Compared to baseline, there was a significant improvement of GLS in the abnormal GLS group at 6‑mo follow-up (p=0.04). Prevalence of complications after AMI was significantly higher in this group. There were significant differences between baseline and discharge NT-proBNP concentrations between the two groups (p<0.05). In the abnormal GLS group, there were significant correlations between baseline and discharge NT-proBNP concentrations with baseline LV systolic function. Discharge NT-proBNP concentration also correlated significantly with 6‑mo follow-up GLS. For determining the effect of baseline GLS abnormality, the areas under the ROC curve for baseline and discharge NT-proBNP concentrations were 0.73 (95 % CI 0.60–0.85, p=0.001) and 0.77 (95 % CI 0.66–0.87, p<0.001), respectively. Regarding early prediction of follow-up GLS abnormality, the area under the ROC curve for discharge NT-proBNP concentration was significantly higher 0.70 (95 % CI 0.55–0.84, p=0.016). The optimum cut-off value of discharge NT-pro-BNP was 688.5 pg / ml, with 72.4 % sensitivity and 65.4 % specificity to predict 6‑mon GLS abnormality following acute myocardial infarction.Conclusion    The main finding of this study is that impaired LV GLS is associated with elevated plasma concentrations of NT-proBNP in post-AMI patients. Pre-discharge NT-proBNP concentration combined with impaired initial GLS could predict worsening LV systolic function over time in asymptomatic post-AMI patients.

The Relationship

Background: Epidemiological data show that the incidence of heart failure after myocardial infarction is about 20%. The incidence of heart failure after acute myocardial infarction is also known to increase post-infarct mortality. The incidence of heart failure is related to the remodelling process after acute myocardial infarction. The acute remodelling process after acute myocardial infarction involves a mechanical mechanism in which there is a change in left ventricular geometry as an adaptive response to the incidence of infarction and then results in increased left ventricular wall stress. Increased left ventricular wall stress can be assessed by measuring global longitudinal strain (GLS) using echocardiography. On the other hand, mechanical overload in the myocardium is known to increase sST2 levels. The relationship between increased levels of sST2 and left ventricular GLS in patients with acute myocardial infarction has never been studied before.Methods: An analytic observational study with a cross-sectional design conducted from July to September 2018 at Dr Sardjito Hospital. Patients diagnosed with acute myocardial infarction and fulfilling the inclusion and exclusion criteria were included in the study. Measurement of sST2 levels and echocardiographic examination was performed on the first day after admission. Correlation test analysis was conducted to determine the relationship between sST2 levels and left ventricular GLS.Results: There were 72 subjects, with 62 STEMI subjects and 10 NSTEMI subjects. The mean level of sST2 in this study was 4,252 ± 198 pg / mL. Measurement of the left ventricular function obtained a mean ejection fraction of 47 ± 9%, LVIDd 45.79 ± 6.2 mm and GLS values of -9.3 ± 3.3%. Correlation test using Spearman test showed that there was no correlation between increased sST2 levels and decreased GLS values in patients with acute myocardial infarction (r = -0.133; p = 0.344).Conclusion: Increased sST2 levels were not correlated with decreased GLS values in patients with acute myocardial infarction.
