Serum Soluble ST2 and Adverse Left Ventricular Remodeling in Patients With ST-Segment Elevation Myocardial Infarction.

ABSTRACT:

Objective

To assess the dynamics of serum levels of soluble isoform of suppression of tumorigenicity 2 (sST2) and N-terminal pro-brain natriuretic peptide (NT-proBNP) and their correlations with the development of adverse left ventricular remodeling (LVR) through 6 months in patients with primary myocardial infarction with ST-segment elevation (STEMI).

Methods

Subjects were 31 patients with STEMI (median age: 58 years), who underwent percutaneous coronary intervention (PCI) during the first 24 hours of the onset of myocardial infarction (MI). Blood samples and parameters of echocardiography were assessed at days 1, 3, 7, and 14 and 6 months after STEMI.

Results

Serum levels of sST2 and NT-proBNP decreased during the 6-month period. Levels of sST2 decreased by 48% from admission to day 7, and levels of NT-proBNP decreased by 40% from day 7 to 6 months after STEMI. Serum levels of sST2 at day 1 (r = 0.5, P < .05) and day 3 (r = 0.4, P < .05) were associated with adverse LVR by 6 months after STEMI. Logistic regression analysis showed that a high concentration of sST2 at day 7 increased the risk of adverse LVR (95% confidence interval [CI], 0.5-0.9; areas under curve [AUC] = 0.8; P = .002), with 92% sensitivity and 70% specificity. A multivariate analysis model revealed that adverse LVR was associated with the level of sST2 (P = .003) and with complete revascularization (P = .01) at the admission.

Conclusions

The dynamics of serum levels of sST2 and NT-proBNP were different. The level of sST2 normalized by the 7th day; NT-proBNP decreased only by the end of the 6-month period after MI. Increased serum levels of sST2 by the 7th day of MI were associated with the development of adverse LVR by the end of the 6-month period.

Project description:ObjectivesYoung patients account for about half of ST-segment elevation myocardial infarction (STEMI) patients and display a unique risk profile compared with old patients. Whether these differences are related to disparities in ventricular remodeling remains unknown. This study aimed to evaluate age-related differences in ventricular remodeling after primary percutaneous coronary intervention (PPCI) for STEMI.MethodsIn this observational study, consecutive STEMI patients between October 2019 and March 2021 who underwent serial cardiovascular magnetic resonance at index admission (3 to 7 days) and 3 months after PPCI were enrolled. Adverse remodeling was defined as ≥ 10% enlargement in left ventricular end-diastolic volume index (LVEDVi), while reverse remodeling was defined as a decrease in left ventricular end-systolic volume index (LVESVi) of more than 10%.ResultsA total of 123 patients were included and grouped into young (< 60 years, n = 71) and old (≥ 60 years, n = 52) patients. Despite generally similar baseline structural and infarct characteristics, LVESVi significantly decreased only in old patients during follow-up (p = 0.034). The incidence of adverse remodeling was higher (49.3% vs 30.8%, p = 0.039), while the incidence of reverse remodeling was lower (31.0% vs 53.8%, p = 0.011) in young compared with old patients. Younger age (< 60 years) was associated with a significantly higher risk of adverse remodeling (adjusted OR 3.51, 95% CI 1.41-8.74, p = 0.007) and lower incidence of reverse remodeling (adjusted OR 0.42, 95% CI 0.18-0.97, p = 0.046).ConclusionsIn STEMI patients undergoing PPCI, young patients are at a higher risk of adverse remodeling and less probably develop reverse remodeling than old patients. Equal or more attention should be paid to young patients with STEMI compared with their older counterparts.Key points• In STEMI patients undergoing PPCI, young patients displayed unfavorable remodeling compared with old patients. • Young patients are at a higher risk of adverse remodeling and less probably develop reverse remodeling than old patients. • Equal or more attention should be paid to young patients compared with their older counterparts.

Project description:ObjectiveTo investigate the predictive value of radiomics features based on cardiac magnetic resonance (CMR) cine images for left ventricular adverse remodeling (LVAR) after acute ST-segment elevation myocardial infarction (STEMI).Materials and methodsWe conducted a retrospective, single-center, cohort study involving 244 patients (random-split into 170 and 74 for training and testing, respectively) having an acute STEMI (88.5% males, 57.0 ± 10.3 years of age) who underwent CMR examination at one week and six months after percutaneous coronary intervention. LVAR was defined as a 20% increase in left ventricular end-diastolic volume 6 months after acute STEMI. Radiomics features were extracted from the one-week CMR cine images using the least absolute shrinkage and selection operator regression (LASSO) analysis. The predictive performance of the selected features was evaluated using receiver operating characteristic curve analysis and the area under the curve (AUC).ResultsNine radiomics features with non-zero coefficients were included in the LASSO regression of the radiomics score (RAD score). Infarct size (odds ratio [OR]: 1.04 (1.00-1.07); P = 0.031) and RAD score (OR: 3.43 (2.34-5.28); P < 0.001) were independent predictors of LVAR. The RAD score predicted LVAR, with an AUC (95% confidence interval [CI]) of 0.82 (0.75-0.89) in the training set and 0.75 (0.62-0.89) in the testing set. Combining the RAD score with infarct size yielded favorable performance in predicting LVAR, with an AUC of 0.84 (0.72-0.95). Moreover, the addition of the RAD score to the left ventricular ejection fraction (LVEF) significantly increased the AUC from 0.68 (0.52-0.84) to 0.82 (0.70-0.93) (P = 0.018), which was also comparable to the prediction provided by the combined microvascular obstruction, infarct size, and LVEF with an AUC of 0.79 (0.65-0.94) (P = 0.727).ConclusionRadiomics analysis using non-contrast cine CMR can predict LVAR after STEMI independently and incrementally to LVEF and may provide an alternative to traditional CMR parameters.

Project description:BackgroundPrimary percutaneous coronary intervention (PPCI) in patients with ST-segment elevation myocardial infarction (STEMI) improves the survival of patients; nevertheless, some patients develop left ventricular adverse remodeling (LVAR) a few months after the intervention. The main objective of this study was to characterize the role of pro-inflammatory cell populations, related cytokines, and microRNAs (miRNAs) released after PPCI as reliable prognostic biomarkers for LVAR in patients with STEMI.MethodsWe evaluated the level of pro-inflammatory subsets, before and after revascularization, 1 and 6 months after PPCI, using flow cytometry. We also performed a miRNA microarray in isolated peripheral blood mononuclear cells (PBMCs) and examined the levels of 27 cytokines in patients' serum of patients by multiplex ELISA.ResultsWe observed that the levels of classical and intermediate monocytes increased 6 h after PPCI in patients who developed LVAR later. Multivariate regression analysis and ROC curves indicated that intermediate monocytes, after PPCI, were the best monocyte subset that correlated with LVAR. Within the 27 evaluated cytokines evaluated, we found that the increase in the level of vascular endothelial growth factor (VEGF) correlated with LVAR. Furthermore, the microarray analysis of PBMCs determined that up to 1,209 miRNAs were differentially expressed 6 h after PPCI in LVAR patients, compared with those who did not develop LVAR. Using RT-qPCR we confirmed a significant increase in miR-16, miR-21-5p, and miR-29a-3p, suggested to modulate the expression of different cytokines, 6 h post-PPCI in LVAR patients. Interestingly, we determined that the combined analysis of the levels of the intermediate monocyte subpopulation, VEGF, and miRNAs gave a better association with LVAR appearance. Similarly, combined ROC analysis provided high accurate specificity and sensibility to identify STEMI patients who will develop LVAR.ConclusionOur data suggest that the combined analysis of intermediate monocytes, VEGF, and miRNAs predicts LVAR in STEMI patients.

Project description:ObjectivesThis study sought to determine the incidence and prognostic significance of persistent iron in patients post-ST-segment elevation myocardial infarction (STEMI).BackgroundThe clinical significance of persistent iron within the infarct core after STEMI complicated by acute myocardial hemorrhage is poorly understood.MethodsPatients who sustained an acute STEMI were enrolled in a cohort study (BHF MR-MI [Detection and Significance of Heart Injury in ST Elevation Myocardial Infarction]). Cardiac magnetic resonance imaging including T2* (observed time constant for the decay of transverse magnetization seen with gradient-echo sequences) mapping was performed at 2 days and 6 months post-STEMI. Myocardial hemorrhage or iron was defined as a hypointense infarct core with T2* signal <20 ms.ResultsA total of 203 patients (age 57 ± 11 years, n = 158 [78%] male) had evaluable T2* maps at 2 days and 6 months post-STEMI; 74 (36%) patients had myocardial hemorrhage at baseline, and 44 (59%) of these patients had persistent iron at 6 months. Clinical associates of persistent iron included heart rate (p = 0.009), the absence of a history of hypertension (p = 0.017), and infarct size (p = 0.028). The presence of persistent iron was associated with worsening left ventricular (LV) end-diastolic volume (regression coefficient: 21.10; 95% confidence interval [CI]: 10.92 to 31.27; p < 0.001) and worsening LV ejection fraction (regression coefficient: -6.47; 95% CI: -9.22 to -3.72; p < 0.001). Persistent iron was associated with the subsequent occurrence of all-cause death or heart failure (hazard ratio: 3.91; 95% CI: 1.37 to 11.14; p = 0.011) and major adverse cardiac events (hazard ratio: 3.24; 95% CI: 1.09 to 9.64; p = 0.035) (median follow-up duration 1,457 days [range 233 to 1,734 days]).ConclusionsPersistent iron at 6 months post-STEMI is associated with worse LV and longer-term health outcomes.
