Purpose: In essential hypertensive patients, cardiac remodeling may be associated with the risk of renal damage in the future which can be reflected by the estimated glomerular filtration rate (eGFR). Through retrospective analysis, we evaluated the potential of cardiac remodeling based on echocardiographic measurements to predict the risk of renal damage in the future with hypertensive patients.
Methods: We retrospectively analyzed the relationship between the changes of left heart structure and function and renal damage for 510 patients with hypertension, who were diagnosed between 2016 to 2022. Demography data, clinical data, blood samples and echocardiographic variables were used for survival analysis, and the Cox proportional hazards regression model was used.
Results: In our study, we found that age, serum creatinine (SCR), creatine kinase isoenzyme MB (CK MB), abnormal high-sensitivity troponin I (TNI), interventricular septum thickness (IVST) and left ventricular ejection fraction (LVEF) could be used as independent predictors in risk of renal impairment in hypertensive patients (p< 0.05). Combined in a score where one point was given for the presence of each of the parameters above, this score could strongly predict renal function damage in the future (p< 0.05). In receiver operating characteristics (ROC) curve analyses, the area under the curve of the risk factor score was 0.849 (P< 0.001).
Conclusion: In essential hypertensive patients, LVEF and IVST can predict the risk of future adverse renal outcomes. Moreover, combining risk variables into a simplified score may enable to assess the risk of renal impairment in hypertensive patients at an early stage.
