The Application Value of Electrocardiogram ST-T Changes in the Diagnosis and Treatment of Elderly Hypertension combined with Coronary Heart Disease
Objective To explore the diagnostic value of electrocardiogram ST-T changes in elderly patients with hypertension and coronary heart disease,in order to provide reference for early clinical diagnosis and intervention plans.Methods One hundred hypertensive patients who visited our hospital from January 2022 to June 2023 were selected as the study group,and another 100 healthy patients who underwent physical examinations during the same period were selected as the control group,all of whom underwent electrocardiogram examinations.Compare the changes in electrocardiogram ST-T(ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,V4T-V6T wave low flat or inverted)between two groups,patients with different hypertension grades and concomitant or non concomitant coronary heart disease,different number of coronary lesion branches,and degree of coronary stenosis,and analyze the correlation between ST-T changes and hypertension grades,coronary lesion branches,and degree of coronary stenosis.Results Compared with the control group,the study group had a higher detection rate of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave low flat or inverted(P＜0.05).Comparison of detection rates of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave low flat or inverted in patients with different hypertension grades:hypertension grade Ⅲ＞hypertension grade Ⅱ＞hypertension grade Ⅰ(P＜0.05).Compared with patients without concomitant coronary heart disease,patients with concomitant coronary heart disease had a higher detection rate of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave flat or inverted(P＜0.05).Comparison of detection rates of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave low flat or inverted in patients with different coronary artery disease branches:multi branch disease＞double branch disease＞single branch disease(P＜0.05).Comparison of detection rates of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave low flat or inverted in patients with different degrees of coronary stenosis:severe stenosis＞moderate stenosis＞mild stenosis(P＜0.05).The detection rates of ST segment ischemic depression,V1-V6T wave upright V1T＞V5T,and V4T-V6T wave low flat or inverted in electrocardiogram were significantly positively correlated with hypertension grade,number of coronary lesion branches,and degree of stenosis(P＜0.05).Conclusion The ST segment changes in electrocardiogram can be used for the diagnosis of elderly hypertension combined with coronary heart disease,providing reference for early clinical evaluation of hypertension and coronary heart disease,and formulating targeted treatment plans.
