Prognostic value of pulmonary vascular resistance estimated by cardiac magnetic resonance in patients with chronic heart failure.
Pulmonary arterial hypertension is known to be related to worse prognosis in patients with heart failure (HF). Quantification of pulmonary vascular resistance (PVR) still requires invasive right heart catheterization. Recent studies have shown an accurate method for non-invasive estimation of PVR by cardiac magnetic resonance (CMR). Our aim was to evaluate the prognostic value of PVR calculated by CMR in patients with congestive HF.We calculated PVR by CMR in 132 patients [age 65.6 ± 13.1 years, left ventricular ejection fraction (LVEF) 35.1 ± 16.4%, ischaemic aetiology 40%] recently admitted for decompensated HF and derived to our cardiac imaging unit for diagnosis. Patients with cardiac e…
Mean velocity of the pulmonary artery estimated by cardiac magnetic resonance as an early prognostic predictor in heart failure.
Background and objective: To identify early, non-invasive prognostic indicators in heart failure (HF), with and without associated pulmonary hypertension, by means of cardiac magnetic resonance, and oxidative stress and anti-inflammatory biomarkers such as Trolox (TM) (antioxidant status) and IL-10 (anti-inflammatory cytokine). Patients and methods: We prospectively included 70 patients admitted for new-onset HF. During index admission, mean velocity of the pulmonary artery (mvPA) was measured, and blood Trolox (TM) and IL-10 determined. The study sample was divided in two groups according to the optimal cut-off value for event prediction calculated by the ROC curve (mvPA = 8 cm/s), conside…
Velocidad media de la arteria pulmonar estimada por resonancia magnética cardiaca como predictor pronóstico precoz en insuficiencia cardiaca
Resumen Introduccion y objetivo La hipertension pulmonar asocia peor pronostico en insuficiencia cardiaca (IC). En este estudio buscamos identificar predictores pronosticos no invasivos en IC con y sin hipertension pulmonar asociada, mediante resonancia magnetica cardiaca y determinacion de marcadores de estres oxidativo y antiinflamatorios. Pacientes y metodos Inclusion prospectiva de 70 pacientes ingresados por IC de comienzo, en los que se determino la velocidad media de arteria pulmonar (vmAP) y la concentracion sanguinea de TroloxTM (estatus antioxidante) e IL-10 (citocina antiinflamatoria). La muestra se dividio en dos grupos de acuerdo con el valor optimo de vmAP para la prediccion d…
