- ItemGalectin-3 levels in patients hospitalized for decompensated heart failure(SOC MEDICA SANTIAGO, 2017) Rossel, Victor; Diaz Toro, Felipe; Verdejo, Hugo; Concepcion, Roberto; Sepulveda, Luis; Castro, Pablo; Luis Vukasovic, Jose; Bernales, Angie; Representacion Departmento InsuficGalectin-3 (Gal-3) is a mediator of myocardial fibrosis involved in cardiac remodeling and a potential new prognosis marker in heart failure (HF). Aim: To measure Gal-3 at the moment of discharge in patients hospitalized for HF and its association with different variables. Material and Methods: Patients hospitalized for decompensated HF from four hospitals between August 2014 and March 2015, were included. Demographic, clinical and laboratory variables were recorded at the time of admission. At discharge, a blood sample was withdrawn to measure Gal-3 and brain natriuretic propeptide (Pro-BNP). Patients were separated in two groups, according to the level of Gal-3 (using a cutoff value of 17.8 ng/mL), comparing clinical and laboratory values between groups. Results: We included 52 patients with HF aged 70 17 years (42% females). Functional capacity was III-IV in 46% of patients and the ejection fraction was 34.9 13.4%. Pro-BNP values at discharge were 5,323 8,665 pg/mL. Gal-3 values were 23.8 16.6 ng/mL. Sixty percent of patients had values over 17.8 ng/mL. Those with elevated Gal-3 levels were older (75 16 and 62 15 years, respectively, p = 0.025) and were hypertensive in a higher proportion (90.5% and 57.1% respectively, p = 0.021). Conclusions: In patients hospitalized for HF, Gal-3 levels are higher in older and hypertensive subjects.
- ItemRelationship between mechanical and metabolic dyssynchrony with left bundle branch block: Evaluation by 18-fluorodeoxyglucose positron emission tomography in patients with non-ischemic heart failure(ELSEVIER SCIENCE INC, 2012) Castro, Pablo; Luis Winter, Jose; Verdejo, Hugo; Orellana, Pilar; Carlos Quintana, Juan; Greig, Douglas; Enriquez, Andres; Sepulveda, Luis; Concepcion, Roberto; Sepulveda, Pablo; Rossel, Victor; Chiong, Mario; Garcia, Lorena; Lavandero, SergioBACKGROUND: Ventricular dyssynchrony is a common finding in patients with heart failure (HF), especially in the presence of conduction delays. The loss of ventricular synchrony leads to progressive impairment of contractile function, which may be explained in part by segmental abnormalities of myocardial metabolism. However, the association of these metabolic disarrangements with parameters of ventricular dyssynchrony and electrocardiography (ECG) findings has not yet been studied.
