Physiologic right left shunt during the acute stage of myocardial infarction ; Shunt fisiologico destro sinistro durante infarto miocardico in fase acuta

Twenty five studies in 12 patients affected by acute myocardial infarction have been performed. A highly significant positive correlation between physiological right to left shunt, cardiac index and cardiac output was found. No correlation between physiological shunt, pulmonary artery and wedge pressure was found. Pathogenesis of physiological shunt and the meaning of its positive correlation with cardiac index and cardiac output are discussed. Therapeutic implications are also considered.
