Abstract

To compare cardiac index (CI), oxygen delivery index (D(O(2))I), oxygen extraction ratio (O(2)ER), oxygen consumption index (V(O(2))I), and systemic vascular resistance index (SVRI) in dogs with naturally occurring sepsis with published values for healthy dogs; compare those variables in dogs with sepsis that did or did not survive; and compare CI and D(O(2))I in dogs with sepsis with values in dogs with nonseptic systemic inflammatory response syndrome (nSIRS). Cohort study. 10 dogs with naturally occurring sepsis and 11 dogs with nSIRS. Over 24 hours, CI, D(O(2))I, O(2)ER, V(O(2))I, and SVRI were measured 4 and 5 times in dogs with sepsis and with nSIRS, respectively. The mean values of each variable in each group were compared over time and between groups; data for dogs with sepsis that did or did not survive were also compared. Mean D(O(2))I was significantly decreased, and mean CI, O(2)ER, V(O(2))I, and SVRI were not significantly different in dogs with sepsis, compared with published values for healthy dogs. Mean CI and D(O(2))I in dogs with sepsis were significantly greater than values in dogs with nSIRS. Among dogs with sepsis that did or did not survive, values of CI, D(O(2)I), O(2)ER, V(O(2))I, and SVRI did not differ...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
