Abstract:Objective To investigate the myocardial status and the value of echocardiography in the detection of cardiac function in patients with acute severe infection under the storm of inflammatory cytokines.Methods A total of 110 patients with acute severe infection treated at the Western Center Hospital in Hainan from January 2020 to February 2023 were selected. Among them, 45 patients with cytokine storm were included in the observation group, and 65 patients without cytokine storm were included in the control group. The differences in clinical data, myocardial injury markers, electrocardiogram, and echocardiographic parameters between the two groups were compared.Results Patients in the observation group were older than those in the control group (P < 0.05). Lactate dehydrogenase, creatine kinase, creatine kinase isoenzyme, cardiac troponin T, cardiac troponin I, and N-terminal pro-brain natriuretic peptide in the observation group were higher than those in the control group (P < 0.05). White blood cell count and neutrophil count in the observation group were higher than those in the control group (P < 0.05), while platelet count and red blood cell count were lower than those in the control group (P < 0.05). The proportion of atrial fibrillation, ventricular premature contraction, atrial premature contraction, and abnormal Q wave in the observation group was higher than that in the control group (P < 0.05). Left ventricular end-diastolic diameter , left ventricular end-systolic diameter, left ventricular end-diastolic volume, left ventricular end-systolic volume , E peak, tricuspid regurgitation pressure gradient, and pulmonary artery systolic pressure in the observation group were higher than those in the control group (P < 0.05), while left ventricular ejection fraction and A peak were lower than those in the control group (P < 0.05). Conclusion Myocardial injury is evident in patients with acute severe infection under the storm of inflammatory cytokines, and echocardiography can visually detect the cardiac condition.
