    • Cardiovascular aging Envejecimiento cardiovascular 
      Domenech Lira, Raúl; Macho Fisher, Pilar (2008)
      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 ...
    • 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 ...
    • 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 ...
    • Effect of tachycardia on myocardial sarcoplasmic reticulum and Ca2+ dynamics: a mechanism for preconditioning? 
      Domenech Lira, Raúl; Sánchez, Gina; Donoso Laurent, Paulina; Parra Morales, Víctor; Macho Fisher, Pilar (ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2003-12)
      We have previously demonstrated that brief episodes of tachycardia prior to a prolonged occlusion of a coronary artery, followed by reperfusion, substantially reduce the infarct size. Adenosine receptors and mitochondrial ...
    • Endothelium and coronary circulation El endotelio y la circulacion coronaria. 
      Domenech, Cristina; Macho Fisher, Pilar (1991)
      In the last few years, so many different substances produced by the endothelium have been discovered that this structure is considered today a paracrine organ. Among these substances, there are at least three with marked ...
    • 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 ...
    • Late cardiac preconditioning by exercise in dogs is mediated by mitochondrial potassium channels 
      Parra, Víctor M.; Macho Fisher, Pilar; Domenech Lira, Raúl (2010)
      We previously showed that exercise induces myocardial preconditioning in dogs and that early preconditioning is mediated through mitochondrial adenosine triphosphate-sensitive potassium channels. We decided to study if ...
