To analyze the clinical examination indicators of heart failure with preserved ejection fraction (HFpEF) patients with deficiency and excess syndrome to explore the characteristics.Methods:Through cross-sectional investigation,general clinical information,blood test and echocardiogram indexes of patients with HFpEF were collected.Then Logistic regression was used to analyze the clinical examination indicators of HFpEF patients with different syndromes.Results:With the syndrome of HFpEF patients as the dependent variable,a binary Logistic regression analysis was performed on the indicators with statistically significant differences,and the final remaining variables were the heart rate (HR) and the ejection fraction (EF).Conclusion:In patients with heart failure with ejection fraction retention,HR and EF are closely related to deficiency and excess syndrome.
