The application value of afterload-related cardiac performance in patients with sepsis-induced cardiomyopathy

Objective To investigate the application value of afterload-related cardiac performance(ACP) in patients with sepsis-induced cardiomyopathy. Methods A total of 148 patients with septic shock admitted by the department of critical care of Wuhan fourth hospital from April 2013 to March 2018 were retrospectively included, all included patients were divided into LVEF 80%), mild heart function impairment group (60% < ACP≤80%), moderate heart function impairment group (40% < ACP≤60%), and severe heart function impairment group (ACP≤40%) according to ACP value, the mortality rate at 28 days was compared in the 4 groups. The measurement data were compared by grouped t test, the rates were compared by chi-square test. Results The mortality rate was 58.2% in the LVEF < 50% group, and 30.9% in the LVEF≥50% group, with statistically significant differences (χ2=11.171, P<0.01). The values of ACP in the LVEF < 50% group were (39.3±16.4) %, and those in the LVEF≥50% group were (69.1±14.9) %, with statistically significant differences (t=11.571, P<0.01).The mortality rate was 14.81% in the normal group, 44.00% in the mild, 58.82% in the moderate and 90.00% in the severe group. The differences between the normal group and the mild and moderate groups were statistically significant, while those between the severe group and the mild and moderate groups were statistically significant. Conclusion Afterload-related cardiac performance is of great value for the diagnosis and prognosis in patients with sepsis-induced cardiomyopathy.
