Relationship Among 24h Average Pulse Pressure Coronary Artery Disease And Arrhythmia In Patients With Essential Hypertension And Coronary Heart Disease

Objective High blood pressure play a greater role in the development of coronary heart disease, Relationship of blood pressure and coronary heart disease is closely.Research shows that dynamic monitoring of pulse pressure is an important predictor of coronary heart disease, hypertension and other cardiovascular events development,PP Can better reflect the extent of the damage target organs.As an independent risk factor, its monitoring value than systolic blood pressure, diastolic blood pressure.Ambulatory blood pressure monitoring and ECG synchronization, which can observe the relationship between changes in blood pressure in patients with arrhythmias and myocardial ischemia.To evaluate the relationship among 24h average pulse pressure(PP),coronary artery disease and arrhythmia in patients with Hypertension(HBP) and Coronary Heart Disease(CHD).Methods 154 Patients diagnosed as CHD and HBP proved by coronary angiography,synchronous monitor 24h ambulatory blood pressure(A BP) and 24h ambulatory electrocardiography(A ECG).They were divided into group A(<50mmhg) and group B(≥50mmhg) based 24h PP.The coronary artery lesion severity and occurrence arrhythmia of two groups were compared. Coronary artery disease were divided into single, double, three.Count with vascular disease, coronary stenosis and coronary artery stenosis integral to represent.Results The incidence of 3 coronary artery disease in group B was higher than group A,P<0.01;The incidence of 2 coronary artery disease, Gensini integrals and coronary stenosis in group B was higher than group A,P<0.05;The incidence of ST-T change and arrhythmia in group B was higher than group A,P<0.05.Conclusion All patients with CHD and HBP were given 24h A BP and 24h A ECG,we find increased pulse pressure and coronary artery disease stenosis,arrhythmia and myocardial ischemia were positively correlated.The rusults show that PP is regarded as one of the more reliable and simple indexes for prognosis of CHD.
