- Abstract: Objective To evaluate the value of color Doppler echocardiography and electrocardiography in assessing cardiac function and disease severity in patients with hypertensive heart disease. Methods A retrospective analysis was conducted on 205 patients with hypertensive heart disease who were categorized into 3 groups based on the New York Heart Association (NYHA) criteria: class II (n=62), class III (n=89) and class IV (n=54). The demographic characteristics (including gender and age) and the results of color Doppler echocardiography and electrocardiography were extracted from the hospitals medical record system for analyzing the relationships of the diagnostic findings from color Doppler echocardiography and electrocardiography with cardiac function and disease severity. Results Electrocardiography revealed statistically significant intergroup differences in QTc interval, QRS voltage, and QRS duration across 3 groups (P<0.05). Among 3 groups, class IV group exhibited the most pronounced abnormalities with prolonged QTc interval and QRS duration, along with reduced QRS voltage (P<0.05). Compared with class II group, class III group had longer QTc interval and QRS duration, alongside lower QRS voltage (P<0.05). Color Doppler echocardiography showed that left ventricular systolic diameter, left ventricular diastolic diameter, left atrial diameter, left ventricular posterior wall thickness, interventricular septum thickness, left ventricular ejection fraction, and E/A ratio differed significantly across 3 groups (P<0.05). Class IV group exhibited the largest left ventricular systolic diameter, left ventricular diastolic diameter and left atrial diameter, the thickest left ventricular posterior wall and interventricular septum, and the lowest left ventricular ejection fraction and E/A ratio (P<0.05). Compared with class II group, class III group had enlarged left ventricular systolic diameter, left ventricular diastolic diameter and left atrial diameter, thicker left ventricular posterior wall and interventricular septum, and reduced left ventricular ejection fraction and E/A ratio (P<0.05). Spearman correlation analysis found that QTc interval, QRS duration, left ventricular systolic diameter, left ventricular diastolic diameter, left atrial diameter, left ventricular posterior wall thickness, and interventricular septum thickness were positively correlated with cardiac functional impairments in patients with hypertensive heart disease, while QRS voltage, left ventricular ejection fraction, and E/A ratio were negatively correlated with cardiac functional impairments in patients with hypertensive heart disease (P<0.05). Multiple linear regression analysis identified QTc interval, QRS duration, left ventricular end-systolic diameter, left ventricular end-diastolic diameter, left atrial diameter, left ventricular posterior wall thickness, ventricular septum thickness, QRS voltage, left ventricular ejection fraction, and E/A ratio as critical factors for assessment of cardiac function (P<0.05). Conclusion Color Doppler echocardiography and electrocardiography demonstrate significant clinical utility in evaluating cardiac function and disease severity in patients with hypertensive heart disease.
