    • Effects of carvedilol on functional capacity, left ventricular function, catecholamines and oxidative stress ... 
      Castro, Pablo; Pérez, Osvaldo; Greig, Douglas; Díaz Araya, Guillermo; Moraga, Francisco; Chiong Lay, Mario; Troncoso, Rodrigo; Padilla, Ivonne; Vukasovic, Jose L.; Corbalán, Ramón; Lavandero González, Sergio (Ediciones Doyma, S.L., 2004)
      Introduction and objective. Carvedilol is an antioxidant and adrenergic antagonist with demonstrated benefits in terms of mortality from heart failure (HF). The aim of the present study was to evaluate clinical parameters, ...
    • Gln27→Gluβ2-adrenergic receptor polymorphism in heart failure patients: Differential clinical and oxidative ... 
      Troncoso Cotal, Rodrigo; Moraga, Francisco; Chiong Lay, Mario; Roldán, Juan; Bravo, Roberto; Valenzuela, Rodrigo; Díaz Araya, Guillermo; Del Campo, Andrea; Sanhueza, Carlos; Rodriguez, Andrea; Vukasovic, José Luis; Mellado, Rosemarie; Greig, Douglas; Castro, Pablo F.; Lavandero González, Sergio (2009)
      We investigated the clinical response of chronic heart failure patients with β2-adrenergic receptor Gln27→Glu polymorphism treated for 6 months with carvedilol, a α/β-antagonist with antioxidant properties. The 6-min. walk ...
    • Heart energy metabolism and its role in the treatment of heart failure Metabolismo energético del corazón ... 
      Castro, Pablo; Gabrielli, Luigi; Verdejo, Hugo; Greig, Douglas; Mellado, Rosemarie; Concepción, Roberto; Sepulveda, Luis; Vukasovic, José Luis; García Nannig, Lorena; Pizarro, Marcela; Pivet, Deisy; Carrillo, Constanza; Tapia, Fabiola; Navarro, Mario; Troncoso, Rodrigo; Baraon (2010)
      It is unknown why heart failure progresses even when patients are treated with the best therapy available. Evidences suggest that heart failure progression is due to loss of neurohumoral blockade in advanced stages of the ...
    • Inflammation and endothelial dysfunction in patients with chronic heart failure Inflamación y disfunción ...
