Aim: MicroRNAs (miRNAs) have been shown to play an important role in the progression of heart failure (HF). The aim of our study was to analyze miRNAs in the blood of patients with transposition of the great arteries and a systemic right ventricle (TGA-RV) in order to identify those that predict worsening HF.Materials and Methods: In 36 patients with TGA-RV, SurePrint™ 8 × 60K Human v21 miRNA microarrays were used to determine the miRNA abundance profiles and compared to 35 age- and gender-matched healthy volunteers (HVs). MiRNAs that were most significantly abundant or best related to worsening HF were further validated by RT-qPCR.Results: Using miRNA array analysis, a total of 50 down-regulated and 56 up-regulated miRNAs were found to be differentially abundant in TGA-RV patients compared to HVs. Six of these 106 miRNAs were significantly related to worsening HF. After validation by RT-qPCR, four miRNAs turned out to be significantly associated with worsening HF, namely miR-150-5p, miR-1255b-5p, miR-423-3p, and miR-183-3p. In the stepwise multivariable Cox regression analysis, ejection fraction of the systemic RV, high sensitive TNT and miR-183-3p were found to be independent predictors of worsening HF (P = 0.001, P = 0.002, and P = 0.001, respectively).Conclusions: In patients with TGA-RV, miR-183-3p is an independent predictor of worsening HF and thus may be used as additional biomarker in the risk assessment of these patients.

Abstract Background The prognostic value of human epididymis protein 4 (HE4) in patients with ischemic cardiomyopathy (ICM) is unknown. Methods A total of 103 patients with ICM were prospectively enrolled in this study from Hunan Provincial People’s Hospital between February 2019 and June 2019. All patients were tested for HE4 levels at baseline and follow-up. Endpoints of the study included cardiovascular death and heart failure-related hospitalization. Results A total of 96 patients with ICM were included for analysis. After a mean follow-up period of 263 (153–313) days, cardiovascular events were observed in 45 patients. Serum HE4 levels in patients with events were significantly higher than those in patients without events [188.70 (113.35–326.82) pmol/L versus 92.90 (61.50–123.20) pmol/L, P < 0.001]. Multivariate Cox regression analysis revealed that HE4 [χ2: 9.602, hazard ratio (HR): 1.003, 95% confidence interval (CI): 1.001–1.005, P = 0.002] and age [χ2: 4.55, HR: 1.044, 95% CI: 1.003–1.085, P = 0.033] were independent predictors of events. After adjusting for age and sex, the risk of events in patients with HE4 > 100.2 pmol/L was higher than that in patients with HE4 ≤ 100.2 pmol/L [HR: 3.372, 95% CI: 1.409–8.065, P < 0.001]. Conclusion HE4 is an independent predictor of cardiovascular death and heart failure-related rehospitalization in patients with ICM.

AbstractBackgroundThe increase in soluble suppression of tumorigenicity 2 (sST2) both in the diagnosis and prognosis of heart failure is well established; however, existing data regarding sST2 values as the prognostic marker after myocardial infarction (MI) are limited and have been conflicting. This study aimed to assess the clinical significance of sST2 in predicting 1-year adverse cardiovascular (CV) events in MI patients.Materials and methodsIn this prospective study, 380 MI patients were included. Participants were grouped into low sST2 (n = 264, mean age: 60.0 ± 12.1 years) and high sST2 groups (n = 116, mean age: 60.5 ± 11.6 years), and all study populations were followed up for major adverse cardiovascular events (MACE) which are composed of CV mortality, target vessel revascularization (TVR), non-fatal reinfarction, stroke and heart failure.ResultsDuring a 12-month follow-up, 68 (17.8%) patients had MACE. CV mortality and heart failure were significantly higher in the high sST2 group compared to the low sST2 group (15.5% vs. 4.9%, p = 0.001 and 8.6% vs. 3.4% p = 0.032, respectively). Multivariate Cox regression analysis concluded that high serum sST2 independently predicted 1-year CV mortality [hazard ratio (HR) 2.263, 95% confidence interval (CI) 1.124–4.557, p = 0.022)]. Besides, older age, Killip class >1, left anterior descending (LAD) as the culprit artery and lower systolic blood pressure were the other independent risk factors for 1-year CV mortality.ConclusionsHigh sST2 levels are an important predictor of MACE, including CV mortality and heart failure in a 1-year follow-up period in MI patients.

Long Term Mortality

Abstract Background Late left ventricular remodeling (LLVR) after the index acute myocardial infarction (AMI) is a common complication, and is associated with poor outcome. However, the optimal definition of LLVR has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding the influence of different LLVR definitions on long-term outcomes in AMI patients undergoing percutaneous coronary intervention (PCI). Purpose To explore the impact of different definitions of LLVR on long-term mortality, re-hospitalization or an urgent visit for heart failure, and identify which definition was more suitable for predicting long-term outcomes in AMI patients undergoing PCI. Methods We prospectively observed 460 consenting first-time AMI patients undergoing PCI from January 2012 to December 2018. LLVR was defined as a ≥20% increase in left ventricular end-diastolic volume (LVEDV), or a &gt;15% increase in left ventricular end-systolic volume (LVESV) from the initial presentation to the 3–12 months follow-up, or left ventricular ejection fraction (LVEF) &lt;50% at follow up. These parameters of the cardiac structure and function were measuring through the thoracic echocardiography. The association of LLVR with long-term prognosis was investigated by Cox regression analysis. Results The incidence rate of LLVR was 38.1% (n=171). The occurrence of LLVR according to LVESV, LVEDV and LVEF definition were 26.6% (n=117), 31.9% (n=142) and 11.5% (n=51), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable Cox regression analysis revealed LLVR of LVESV definition [hazard ratio (HR): 2.50, 95% confidence interval (CI): 1.19–5.22, P=0.015], LLVR of LVEF definition (HR: 16.46, 95% CI: 6.96–38.92, P&lt;0.001) and LLVR of Mix definition (HR: 5.86, 95% CI: 2.45–14.04, P&lt;0.001) were risk factors for long-term mortality, re-hospitalization or an urgent visit for heart failure. But only LLVR of LVEF definition was a risk predictor for long-term mortality (HR: 6.84, 95% CI: 1.98–23.65, P=0.002). Conclusions LLVR defined by LVESV or LVEF may be more suitable for predicting long-term mortality, re-hospitalization or an urgent visit for heart failure in AMI patients undergoing PCI. However, only LLVR defined by LVEF could be used for predicting long-term mortality. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Background: To explore the miR-4787-3p expression levels in the serum exosome and tissue and its role in lymph node metastasis and prognosis in ESCC. Methods: The miRNA array was conducted to detect the ESCC serum exosomal miRNAs expression. A receiver operating characteristic (ROC) curve was constructed to determine the predictive ESCC with lymph node metastasis efficacy of serum exosomal miR-4784-3p. The Cox regression analysis was preformed to explore prognostic factors for ESCC. Transwell assay and CCK-8 assays were utilized to evaluate cell migration, invasion, and proliferation, respectively. Results: High serum exosomal miR-4787-3p expression was demonstrated in lymph node metastasis group (P =0.011). The serum exosomal miR-4787-3p expression was significantly associated with histologic grade (P = 0.010), and TNM stage (P = 0.033). However, there was no significant relationship between tissue miR-4787-3p expression and clinical characteristics (P >0.05). ROC analyses revealed that the AUCs of serum exosomal miR-4787-3p for lymph node metastasis prediction was 0.787. The Cox regression analysis found that high expression serum exosomal miR-4787-3p were correlated with poor prognoses (for OS, HR=2.68, 95% CI: 1.02~7.04; for DFS, HR = 2.65, 95% CI: 1.05~6.68). Nevertheless, no association between tissue miR-4787-3p expression and ESCC prognosis. In addition, upregulated expression of miR-4787-3p could promote migration and invasion in vitro. Conclusions: Serum exosomal miR-4787-3p can be promising biomarkers for ESCC metastasis and prognosis

Background: Over the past decade, the FDA has approved several new medications that are highly effective when added to existing standard therapy in the treatment of heart failure with reduced ejection fraction (HFrEF). It is possible that, despite the presence of substantial evidence regarding the clinical effectiveness of these new medications, their high cost and the complex medical reimbursement system in America may prevent their routine adoption. Methods: We analyzed 5,824 Intermountain Healthcare patients, age ≥18 years with a new clinical diagnosis of HFrEF (LVEF ≤35%), from 1/1/2015 onward, for the use of newly-approved sacubitril/valsartan or any sodium-glucose cotransporter-2 inhibitor (SGLT2-I). We collected baseline characteristics and medication utilization data. We followed the patients for 1.7±1.4 years for future major adverse cardiovascular events (MACE), including death, myocardial infarction (MI), stroke, and heart failure hospitalization (HFH). We identified differences between groups by multivariable Cox regression analysis. Results: Baseline characteristics and incidence of MACE, according to insurance status and the use of common HFrEF medications, are shown in the Table. Overall, only 344 (5.9%) and 169 (2.9%) of patients ever received a prescription for sacubitril/valsartan or an SGLT2 inhibitor, respectively. The figures show survival curves for MACE of patients receiving or not receiving the newly-approved medications. Conclusion: In this large, modern, real-world HFrEF population, the adoption of newly-approved evidence-based HFrEF medications is minimal in all patients and especially in Medicare patients. This lack of adoption is associated with a significant worsening in patient outcomes. These findings demonstrate a critical need to resolve our present healthcare financial crisis, which is almost certainly the reason for these findings.

Periprocedural bleeding is one of the most frequent complications of percutaneours coronary interventions. We assessed the relation between blood transfusion and all-cause mortality or incident cardiovascular events (death, MI, stroke) among 6103 patients of the Evaluation of Oral Xemilofiban in Controlling Thrombotic Events (EXCITE)-trial. Subjects were followed for 7 months after enrollment for the occurrence of events. Multivariate Cox-regression analysis evaluated the independent association of blood transfusion with each outcome adjusted for age, gender, race, diabetes mellitus, hypertension, hypercholesterolemia, history of MI, PCI, CABG, heart failure, LVEF<30%, use of beta-blockers, statins, ACE-inhibitors, platelet inhibitors and allocation to treatment with xemolifiban. In addition, propensity score analyses were performed (ROC 0.80). Mean age was 59.2 years, 21.7% were female, and 18.9% had diabetes mellitus. Of the169 patients who received blood transfusion, 14 (8.3%) died and 42 (24.9%) experienced a CVD event. Of the 5934 patients without transfusion, 65 (1.1%) died (p-value: <0.001) and 555 (9,4%) experienced a CVD event (p-value: <0.001) In multivariate analysis, blood transfusion was associated with a 5.3 fold increased risk of mortality (HR 5.3; 95% CI 2.8 –10.2), and a 2.5 fold increased risk of incident CVD (HR 2.5; 95% CI 1.7–3.4.) Noteworthy, patients who were US citizens had a higher transfusion rate then non-US citizens (OR 1.45, 95%CI 1.02–2.06) The need of blood transfusion is a strong and independent predictor of all-cause mortality and incident CVD events among patients undergoing PCI.

BACKGROUND: Left atrial(LA) interstitial fibrosis is known to be a key contributor to atrial fibrillation(AF) development and maintenance. The role of galectin-3 in the pathogenesis of cardiac fibrosis has been demonstrated in previous studies. We aimed to determine whether serum galectin-3 level is an independent predictor for the late AF recurrence in patients with lone AF who underwent cryoballoon- based pulmonary ven isolation(PVI). METHODS: 100 patients (43.80% male, 56.95± 11.36 years) with lone AF who underwent cryoballoon-based PVI were included in the study. Pre-procedural galectin-3 levels were measured with ELISA. RESULTS: At a follow-up of 12 months, 76 (76%) patients were free of late AF recurrence. Body mass index(BMI) ( 25.04± 1.54 vs. 23.93± 2.08 kg/m2, p=0.002), AF duration [7 (3- 20) vs. 5 (1- 24) months, p=0.024], serum galectine-3 levels [11.10 (4.20- 33.80) vs. 5.70 (2.60- 12.40) ng/mL, p<0.001], left atrial diameter(LAD) (4.30± 0.40 vs.3.79± 0.42 cm, p<0.001) and incidence of early recurrence (60 vs 2%, p<0.001) were found to be significantly higher in patients with late AF recurrence. Serum galectin-3 levels (HR: 1.16, p<0.001), LAD (HR: 3.38, p= 0.042) and early recurrence (HR: 10.92, p<0.001) were found to be independent predictors of late AF recurrence in the multivariate Cox regression analysis. A cut-off level for serum galectin-3 level of 7.9 ng/mL predicted late AF recurrence in lone AF patients with a sensitivity of 93.33% and specificity of 87.76% (AUC: 0.910, p<0.001). CONCLUSION: Pre-procedural serum galectin-3 level is an independent predictor of late AF recurrence following cryoballoon-based PVI in patients with lone AF. Galectin-3 may serve as a novel biomarker to identify patients with high recurrence risk following AF ablation.

Background: Methamphetamine (MA) use is rising, and overdose deaths have increased by 500% in San Francisco since 2008. MA use is associated with heart failure (HF); yet, cardiovascular (CV) outcomes in this population have not been described. Methods: We performed a retrospective case-control study of HF patients at a safety net hospital in San Francisco. Between January 2001-June 2019, 1771 HF patients with MA use were matched by age and gender to 3542 HF patients without MA use. We examined age and gender-adjusted associations of MA use with likelihood of index HF admission and 30-day readmission (HF and all-cause), and used demographic-adjusted Cox regression model with competing risks to compare hazard rates associated with MA use over the 18-year study period. Results: At time of HF diagnosis, mean age was 52 years and 77% were male. Patients with MA use were significantly more likely than non-MA users to be black (49.1% vs 33.0%), and to have comorbid conditions including HIV (14.5% vs 4.7%), pulmonary hypertension (11.1% vs 7.7%), hypertension (82.0% vs 77.6%), and cocaine use (58.0% vs 14.7%). Despite similar rates of coronary artery disease, myocardial infarction, and diabetes, HF patients with MA use were less likely to have percutaneous coronary intervention (6.1% vs 8.2%) or coronary artery bypass graft (0.8% vs 1.4%), p<0.05 for all. Compared to HF patients without MA use, HF patients with MA use had higher rates of index HF hospitalizations (36.0% vs 21.7%, adjusted odds ratio 2.04, 95% CI 1.80-2.32, p<0.01), 30-day HF readmission (12.2% vs 6.4%, adjusted hazard ratio (aHR) 1.87, 95% CI 1.31-2.67, p<0.01) and 30-day all cause readmission (20.9% vs 14.3%, aHR 1.46, 95% CI 1.14-1.88, p<0.01). Exposure to MA was associated with higher likelihood of death during the study period, regardless of hospitalizations (22.4% vs 15.1%, aHR=1.17, 95% CI 1.03-1.33, p<0.01). Conclusions: In our study, HF patients with MA use were more likely to be admitted for an index HF admission; subsequently, they were also more likely to be readmitted within 30 days. Regardless of hospitalization risk, individuals with MA use had higher likelihood of death. Further study to understand the clinical and socioeconomic factors driving worse outcomes in this high-risk population is needed.

Abstract Background CHA2DS2-VASc score has been used as a surrogate marker for predicting outcomes beyond thromboembolic risk in patients with atrial fibrillation (AF). Likewise, cardiac troponin I (cTnI) is a predictor of mortality in AF. Purpose This study aimed to investigate the association of cTnI and CHA2DS2-VASc score with long-term prognosis in patients admitted to the emergency department with AF. Methods A retrospective cohort study conducted between January 2012 and December 2013, enrolling patients admitted to the emergency department with AF and having documented cTnI measurements. CHA2DS2-VASc score was estimated. Primary endpoint was 5-year all-cause mortality, readmission for heart failure (HF), readmission for myocardial infarction (MI) and the composite end point of major adverse cardiac events defined as death, readmission for HF or readmission for MI (MACE). Results A total of 578 patients with AF were studied, of whom 252 patients had elevated levels of cTnI (43.6%) and 334 patients had CHA2DS2-VASc score >3 (57.8%). Patients with elevated cTnI tended to be oldercompared with those who did not have cTnI elevation and were more frequently comorbid and of higher ischemic risk, including hypertension, prior MI, prior HF, chronic renal failure and peripheral artery disease. The overall median CHA2DS2-VASc score was higher in those with cTnI elevation compared to those patients elevated cTnI levels (4.2 vs 3.3 points, p<0.001). Main diagnoses at hospital discharge were tachyarrhythmia 30.3%, followed by heart failure 17.7%, respiratory infections 9.5% and acute coronary syndrome 7.3%. At 5-year follow-up, all-cause death was significantly higher for patients with cTnI elevation compared with those who did not have cTnI elevation (56.4% vs. 27%; logrank test p<0.001). Specifically, for readmissions for HF and readmissions for MI there were no differences in between patients with or without cTnI elevation. In addition, MACE was reached in 165 patients (65.5%) with cTnI elevation, compare to 126 patients (38.7%) without cTnI elevation (p<0.001). On multivariable Cox regression analysis, cTnI elevation was an independent predictor of all-cause death (hazard ratio, 1.67, 95% confidence interval [CI]: 1.24–2.26, p=0.001) and of MACE (hazard ratio 1.47, 95% confidence interval 1.15–1.88; P=0.002), but it did not reach statistical significance for readmissions for MI and readmissions for HF. CHA2DS2-VASc score was a predictor on univariate Cox regression analysis for each endpoint, but it did not reach significance on multivariable Cox regression analysis for any endpoint. Conclusions cTnI is independently associated with long-term all-cause mortality in patients attending the emergency department with AF. cTnI compared to CHA2DS2-VASc score is thus a biomarker with predictive capacity for mortality in late follow-up, conferring utility in the risk stratification of patients with atrial fibrillation.
