Abstract Background Elevated pre-procedural high-sensitivity troponin T (hs-TnT) levels predict adverse outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). It is unknown whether elevated troponin levels still provide prognostic information during follow-up after successful TAVR. We evaluated the long-term implications of elevated hs-TnT levels found at 1-year post-TAVR. Methods and results The study included 349 patients who underwent TAVR for severe AS from 2010–2019 and for whom 1-year hs-TnT levels were available. Any required percutaneous coronary interventions were performed > 1 week before TAVR. The primary endpoint was survival time starting at 1-year post-TAVR. Optimal hs-TnT cutoff for stratifying risk, identified by ROC analysis, was 39.4 pg/mL. 292 patients had hs-TnT < 39.4 pg/mL (median 18.3 pg/mL) and 57 had hs-TnT ≥ 39.4 pg/mL (median 51.2 pg/mL). The high hs-TnT group had a higher median N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, greater left ventricular (LV) mass, higher prevalence of severe diastolic dysfunction, LV ejection fraction < 35%, severe renal dysfunction, and more men compared with the low hs-TnT group. All-cause mortality during follow-up after TAVR was significantly higher among patients who had hs-TnT ≥ 39.4 pg/mL compared with those who did not (mortality rate at 2 years post-TAVR: 12.3% vs. 4.1%, p = 0.010). Multivariate analysis identified 1-year hs-TnT ≥ 39.4 pg/mL (hazard ratio 2.93, 95% CI 1.91–4.49, p < 0.001), NT-proBNP level > 300 pg/mL, male sex, an eGFR < 60 mL/min/1.73 m2 and chronic obstructive pulmonary disease as independent risk factors for long-term mortality after TAVR. Conclusions Elevated hs-TnT concentrations at 1-year after TAVR were associated with a higher long-term mortality. Graphic abstract

Abstract Aim Cardiotoxicity (CTox) is a major side effect of cancer therapies, but uniform diagnostic criteria to guide clinical and research practices are lacking. Methods and results We prospectively studied 865 patients, aged 54.7 ± 13.9; 16.3% men, scheduled for anticancer therapy related with moderate/high CTox risk. Four groups of progressive myocardial damage/dysfunction were considered according to current guidelines: normal, normal biomarkers (high-sensitivity troponin T and N-terminal natriuretic pro-peptide), and left ventricular (LV) function; mild, abnormal biomarkers, and/or LV dysfunction (LVD) maintaining an LV ejection fraction (LVEF) ≥50%; moderate, LVD with LVEF 40–49%; and severe, LVD with LVEF ≤40% or symptomatic heart failure. Cardiotoxicity was defined as new or worsening of myocardial damage/ventricular function from baseline during follow-up. Patients were followed for a median of 24 months. Cardiotoxicity was identified in 37.5% patients during follow-up [95% confidence interval (CI) 34.22–40.8%], 31.6% with mild, 2.8% moderate, and 3.1% with severe myocardial damage/dysfunction. The mortality rate in the severe CTox group was 22.9 deaths per 100 patients-year vs. 2.3 deaths per 100 patients-year in the rest of groups, hazard ratio of 10.2 (95% CI 5.5–19.2) (P &lt; 0.001). Conclusions The majority of patients present objective data of myocardial injury/dysfunction during or after cancer therapy. Nevertheless, severe CTox, with a strong prognostic relationship, was comparatively rare. This should be reflected in protocols for clinical and research practices.

Abstract Background Some studies reported utility of microRNAs in myocardial infarction diagnostic process, whereas their prognostic remains unclear. Aim To evaluate the prognostic value of five circulating miRs (miR-1, miR-21, miR-133a, miR-208, miR-499) levels for predicting major adverse cardiac events (MACE), including death, nonfatal myocardial infarction (MI) or cardiovascular rehospitalization (reh.) in patients with NSTE-ACS. Material and methods In our prospective, single-center observational study we recruited patients (pts) with NSTE-ACS with symptoms onset &lt;24 hours before the hospital admission and age, gender-matched patients with stable coronary artery disease (SCAD) as controls. Blood was sampled twice (at admission and 4h after in NSTE-ACS and once in SCAD). Relative expression of miRs were calculated using the ΔΔCt method after normalization to the cel-miR-39 spiked-in control. The mean value of miRs relative expression from two time samples in NSTE-ACS pts were used for further analysis. Subjects were categorized according to mean miRs expression at hospital admission into two group (≤ or &gt; median level of miRs). Results 103 NSTE-ACS pts (median age 67 years, 68% male) were included in this study. During median 1569 (IQR 935–1842) days of follow-up the primary endpoint (MACE) occurred in 66 (64.1%) pts: 18 pts (18.7%) died, 30 pts (20%) presented with MI and 85 pts (56.7%) were readmitted. In a Cox proportional-hazards regression model miR-499 expression &gt; median level (HR=1.82, 95% CI 1.07–3.09) and high-sensitivity troponin T level (HR=1.24, 95% CI 1.05–1.46) were independent predictors of MACE in long term observation, even after adjustment for other covariates (including other miRNAs). Incidence of MI [34% vs 10%, HR=4.1 (2.0–8.5)], rehospitalization for cardiovascular reasons [67% vs 49%, HR=2.1 (1.3–3.3)] and MACE [76% vs 55%, HR=2.2 (1.5–3.5)] was significantly higher in pts with elevated (&gt; median) miR-499 levels at hospital admission. None of analyzed miRNAs was related to long-term mortality, whereas the left ventricular ejection fraction (EF) has been identified as the only one survival predictor (HR=0.95, 95% CI 0.92–0.98). Conclusions Elevated miR-499 levels independently of high sensitivity troponin T levels in early phase of NSTE-ACS are related to increased rate of MACE in 4-year follow-up.
