Predictive value of noninvasive hemodynamics testing indices on prognosis of vulnerable stage of heart failure
Objective To investigate the predictive value of noninvasive hemodynamics testing indices on prognosis of vulnerable stage of heart failure.Methods A total of 85 patients with chronic heart failure hospitalized in the Chengde Central Hospital from November 2021 to November 2022 were randomly selected,and their medication treatment,re-visit,re-hospitalization and death within 3 months after discharge were recorded.Multivariate logistic regression analysis was used to analyze the factors impacting the prognosis of vulnerable stage of heart failure.Results A total of 85 patients were followed up,in which 26 patients had poor prognosis.The left ventricular ejection fraction(LVEF),cardiac output(CO),cardiac index(CI)and left ventricular stroke work(LCW)in patients with poor prognosis were all lower than those in patients with good prognosis,with statistically significant differences(P＜0.05).The level of thoracic fluid content(TFC)and systemic vascular resistance(SVR)in patients with poor prognosis were higher than those in patients with good prognosis,with statistically significant differences(P＜0.05).In the above,LVEF,LCW and TFC were the prognostic factors for prognosis of vulnerable stage of chronic heart failure(P＜0.05).Conclusion Noninvasive hemodynamic indices such as LVEF,LCW and TFC are important prognostic factors of the vulnerable stage of heart failure patients,which may have predictive value for the prognosis of the vulnerable stage of heart failure and have reference significance for guiding the clinical treatment of patients with chronic heart failure.
