Afterload-related cardiac performance (ACP) was developed to describe cardiac function in patients with sepsis, when cardiac output (CO) is increased due to a decline in systemic vascular resistance (SVR). We now studied the prognostic relevance of ACP in comparison with the cardiac index (CI) and cardiac power index (CPI) in patients at a very early stage of community-acquired sepsis (CAS) in the Emergency Department.
In patients ≥18 years admitted to our Emergency Department with CAS (infection and ≥2 SIRS criteria), CI, CPI, and ACP were measured either non-invasively (TaskForce-Monitor; CNSystems, Austria) or invasively. ACP was calculated as ACP = 100 × CO/(560.68 × SVR-0.64). Cardiac function was graded into normal (> 80%), slightly (61 to 80%), moderately (41 to 60%) or severely impaired (≤40%).
Taken together, only the parameter ACP but not CI nor CPI is able to detect an early impairment of cardiac function in patients with CAS and provides prognostic information on admission.
