Clinical Characteristics and Predictors of Adverse Outcomes in HFpEF

Differences in clinical characteristics, history, laboratory biomarkers, echocardiographic measurements, angiographic findings, coronary microvascular function using caIMR and clinical outcomes were assessed between the two groups to identify potential risk factors. Subsequently, the incidence of clinical outcomes and mortality was compared. Univariate logistic regression and multivariate logistic regression analyses, adjusted for significant risk factors, were conducted to identify independent predictive factors. Finally, a Receiver Operating Characteristic (ROC) curve was generated, and the area under the curve was evaluated to assess the predictive accuracy of the regression model.
