Prognostic value of echocardiographic and Doppler parameters in horses admitted for colic complicated by systemic inflammatory response syndrome.
Abstract: To assess the prognostic value of echocardiographic parameters of left ventricular (LV) function in horses with systemic inflammatory response syndrome (SIRS). Methods: Prospective observational study. Methods: Veterinary teaching hospital. Methods: Forty-one horses admitted for colic with clinical evidence of SIRS. Methods: All horses underwent Doppler echocardiographic examination on admission. LV echocardiographic parameters, including pulsed-wave tissue Doppler imaging parameters, were compared between nonsurvivors (n = 29) and horses that survived to discharge (n = 12). Results: With comparable heart rate and LV preload estimate, LV stroke volume index, the velocity time integral, deceleration time, ejection time of Doppler aortic flow, and peak early diastolic myocardial velocity were lower in the nonsurviving than in the surviving horses, while pre-ejection period to ejection time ratio (PEP/ET) of Doppler aortic flow and the peak early diastolic filling velocity to peak early diastolic myocardial velocity ratio (E/Em) were higher (P < 0.05). A cut-off value of 0.26 for PEP/ET predicted mortality with 100% sensitivity and 42% specificity (area under the receiver operating characteristic curve: 0.71), whereas a cut-off value of 2.67 for E/Em predicted mortality with 100% sensitivity and 83% specificity (area under the receiver operating characteristic curve: 0.89). Conclusions: Echocardiography may provide prognostic information in colic horses with clinical evidence of SIRS. Especially, PEP/ET and E/Em could be useful markers of systolic and diastolic dysfunction, respectively, to detect horses with a high risk of death requiring more intensive cardiovascular monitoring as it has been reported in human patients with septic shock.

This study explored the prognostic significance of certain heart function parameters in horses suffering from systemic inflammatory response syndrome (SIRS) complicated by colic. Specific echocardiographic measurements were conducted with hopes of using these findings to recognize horses at high risk of mortality.
Methodology
- The study was a prospective observational research carried out in a veterinary teaching hospital.
- It involved a total of 41 horses, all of which were admitted due to colic and had observed evidence of SIRS.
- All the participating horses underwent Doppler echocardiographic examination upon their arrival at the hospital.
- A comparison was subsequently made between survivors and non-survivors. The comparison was in respect to echocardiographic parameters pertaining to the left ventricular (LV) functionality, including pulsed-wave tissue Doppler imaging parameters.
Key Findings
- In instances where the heart rate and LV preload estimate were similar, non-survivors had lower velocity time integral, LV stroke volume index, ejection time of Doppler aortic flow, and deceleration time.
- Furthermore, both the pre-ejection period to ejection time ratio (PEP/ET) of Doppler aortic flow and the peak early diastolic filling velocity to peak early diastolic myocardial velocity ratio (E/Em) were found to be higher in horses that eventually died.
- A PEP/ET cutoff of 0.26, and an E/Em cutoff of 2.67 were found to be strong predictors of mortality. The parameters showed sensitivity of 100% while the specificity stood at 42% and 83% respectively.
Conclusions and Significance
- The findings from the research indicate that echocardiography could provide valuable prognostic information for horses with SIRS complicated by colic.
- Specifically, the PEP/ET and E/Em parameters could be beneficial in detecting horses that are at an escalated risk of death. This information could then be used to inform a more intensive cardiovascular monitoring strategy for these at-risk horses.
- Similar research variables have been reported in human patients suffering from septic shock, thus deeper understanding about parallel treatment improvements in veterinary and human medicine can be gained.
