    • Changes in total and transmural coronary blood flow induced by ethanol 
      Pescio, Sergio; Macho Fisher, Pilar; Penna Varela, Mario; Domenech Lira, Raúl (Oxford University Press, 1983)
      Summary: We studied the effects of ethanol on total coronary resistance and on the resistance across the left ventricular wall in the isolated empty beating heart of the dog. The coronaries were perfused with homologous ...
    • Contractilidad ventricular. Fisiología y proyección clínica 
      Domenech Lira, Raúl; Parra Morales, Víctor (Soc Médica Santiago, 2016)
      The contractile state of the heart is the result of myocardial contractility, the intrinsic mechanism that regulates the force and the shortening of the ventricle and determines the ventricular ejection volume. However, ...
    • Effect of left intraventricular pressure on magnitude of vascular waterfall in the epicardial coronary veins 
      Domenech Lira, Raúl; Macho Fisher, Pilar; Barros, Felipe (Oxford University Press, 1990)
      Study objective - The aim was to test the hypothesis of a vascular waterfall in the epicardial veins due to compression by the left ventricular (LV) pressure. If this were so, the epicardial venous pressure should be a ...
    • Envejecimiento cardiovascular 
      Domenech Lira, Raúl; Macho Fisher, Pilar (SOC MEDICA SANTIAGO, 2008-12)
      Aging produces its own cardiovascular changes, mainly remodelling of arteries, heart and the microcirculation. These progressive changes, detected since adolescence, represent a major risk factor for the development of ...
    • Preconditioning - A new concept about the benefit of exercise 
      Domenech Lira, Raúl (LIPPINCOTT WILLIAMS & WILKINS, 2006-01-03)
      Case presentation: A 45-yearold man with coronary artery disease is found to be in good condition after his annual medical checkup, and his doctor advises him to continue with the same drugs, a prudent diet, ...
    • Supplementation of underfed twin-bearing ewes with herbal vitamins C and E: Impacts on birth weight, postnatal ... 
      Parraguez Gamboa, Víctor; Sales, Francisco; Peralta Troncoso, Óscar; Narbona Narbona, Eileen; Lira, Raúl; Reyes Solovera, Mónica de los; González Bulnes, Antonio (MDPI, 2020)
      Simple Summary In twin-bearing ewes, undernourishment during pregnancy lowers the birth weight and increases morbidity and mortality of lambs. One of the causes is oxidative stress, which can be prevented by supplementing ...
    • Tachycardia preconditions infarct size in dogs: Role of adenosine and protein kinase C 
      Domenech Lira, Raúl; Macho Fisher, Pilar; Vélez, Diego; Sánchez, Gina; Liu, Xueliang; Dhalla, Naranjan (Lippincott Williams and Wilkins, 1998)
      Background - Myocardial ischemic preconditioning is a well-known phenomenon, however there is scant information in regard to nonischemic preconditioning. Methods and Results - We studied in anesthetized dogs the preconditioning ...
    • Ventricular contractility. Physiology and clinical projection Contractilidad ventricular. Fisiología y ... 
      Domenech Lira, Raúl; Parra, Víctor M. (Sociedad Medica de Santiago, 2016)
      © 2016, Sociedad Medica de Santiago. All rights reserved. The contractile state of the heart is the result of myocardial contractility, the intrinsic mechanism that regulates the force and the shortening of the ventricle ...
