Differential Prognostic Value of Galectin-3 According to Carbohydrate Antigen 125 Levels in Transcatheter Aortic Valve Implantation

2019

Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have been associated with adverse outcomes after transcatheter aortic valve implantation (TAVI). Experimental data have suggested a potential molecular interaction. Therefore, we assessed the association of Gal-3 and CA125 with prognosis after TAVI.A total of 439 patients were enrolled. The primary endpoint was a composite of all-cause mortality or readmission for worsening heart failure after TAVI.The primary endpoint occurred in 16.4%. Gal-3 was dichotomized at ≥ 8.71 ng/mL into elevated and not elevated. Gal-3 was elevated in 31.9% and was associated with a higher risk of the primary endpoint (25% vs 12.4%, HR, 2.26; P.001). After m…

KCND3 is a novel susceptibility locus for early repolarization

2019

AbstractThe presence of an early repolarization pattern (ERP) on the surface electrocardiogram (ECG) is associated with risk of ventricular fibrillation and sudden cardiac death. Family studies have shown that ERP is a highly heritable trait but molecular genetic determinants are unknown. We assessed the ERP in 12-lead ECGs of 39,456 individuals and conducted a two-stage meta-analysis of genome-wide association studies (GWAS). In the discovery phase, we included 2,181 cases and 23,641 controls from eight European ancestry studies and identified 19 genome-wide significant (p<5E-8) variants in the KCND3 (potassium voltage gated channel subfamily D member 3) gene with a p-value of 4.6E-10. …

Valor pronóstico diferencial de la galectina-3 según los valores de antígeno carbohidrato 125 para el implante percutáneo de válvula aórtica

2019

Resumen Introduccion y objetivos La galectina-3 (Gal-3) y el antigeno carbohidrato 125 (CA125) han mostrado relacion con eventos adversos tras el implante percutaneo de valvula aortica (TAVI). Datos experimentales indican que podrian tener cierta interaccion molecular. El objetivo del presente estudio es establecer la asociacion de Gal-3 y CA125 con el pronostico tras el TAVI. Metodos Se incluyo en total a 439 pacientes. El objetivo primario fue el compuesto de mortalidad por todas las causas o reingreso por insuficiencia cardiaca tras el TAVI. Resultados El objetivo primario se produjo en el 16,4% de la muestra. Los valores de Gal-3 se dicotomizaron en elevados (≥ 8,71 ng/ml) y no elevados…

KCND3 potassium channel gene variant confers susceptibility to electrocardiographic early repolarization pattern

2019

BACKGROUND: The presence of an early repolarization pattern (ERP) on the surface ECG is associated with risk of ventricular fibrillation and sudden cardiac death. Family studies have shown that ERP is a highly heritable trait, but molecular genetic determinants are unknown. METHODS: To identify genetic susceptibility loci for ERP, we performed a GWAS and meta-analysis in 2,181 cases and 23,641 controls of European ancestry. RESULTS: We identified a genome-wide significant (P < 5 × 10(–8)) locus in the potassium voltage-gated channel subfamily D member 3 (KCND3) gene that was successfully replicated in additional 1,124 cases and 12,510 controls. A subsequent joint meta-analysis of the discov…

Determinants of elevated carbohydrate antigen 125 in patients with severe symptomatic aortic valve stenosis referred for transcatheter aortic valve i…

2018

Elevated carbohydrate antigen 125 (CA125) predicts adverse outcome after transcatheter aortic valve implantation (TAVI). While known underlying pathophysiological mechanisms of elevated CA125 include serosal effusions and inflammatory stimuli, clinical determinants associated with elevated CA125 in patients referred for TAVI remain unknown. Therefore, we investigated clinical, laboratory and echocardiographic determinants of elevated CA125 in patients with severe aortic valve stenosis referred for TAVI.This study includes 650 patients with severe aortic stenosis referred for TAVI. Baseline CA125 was determined by an immunoassay and dichotomized (elevated versus normal) based on the manufact…

Comparison of Carbohydrate Antigen 125 and N-Terminal Pro-Brain Natriuretic Peptide for Risk Prediction After Transcatheter Aortic Valve Implantation

2017

Elevated carbohydrate antigen 125 (CA125) and N-terminal pro-brain natriuretic peptide (NTproBNP) have been associated with adverse outcome after transcatheter aortic valve implantation (TAVI). This study performs a comparison of both biomarkers for prognosis after TAVI. The study includes 363 patients. The primary end point was all-cause death or readmission for worsening congestive heart failure within 1 year after TAVI, and this end point occurred in 16% of the population. The optimal cutoff to predict the primary end point was 18.4 U/ml for CA125 and 2,570 ng/L for NTproBNP. Elevated CA125 levels were present in 52% and were associated with a higher rate of the primary end point (27% vs…
