Abstract：Objective To discuss the correlation between 24-h pulse pressure (24-h PP) and ambulatory and severity of coronary artery lesion. Methods The patients (n=230) accepted coronary angiography (CAG) and diagnosed as suspected coronary heart disease (CHD) were chosen from Aug. 2011 to Mar. 2013. All patients were given ambulatory blood pressure monitoring (ABPM) and CAG, and Gensini scoring. The difference in the level of 24-h PP was compared among patients with normal coronary artery and those with lesions of different coronary vessels. The coronary stenosis was compared between 24-h PP<50 mmHg group and 24-h PP≥50mmHg group. The relationship between coronary lesion and 24-h PP was analyzed by using binary Logistic regression analysis. Results The level of 24-h PP was significantly higher in 2-vessel lesion group and 3-vessel lesion group than that in normal group (P<0.05). The lesion rate of coronary artery and Gensini integrals were significantly higher in 24-h PP≥50mmHg group than those in 24-h PP<50 mmHg group (P<0.05). Logistic regression analysis showed that the level o f24-h PP was an independent risk factor (OR=1.14, 95%CI:1.07-1.53) of CHD coronary stenosis. Conclusion The level of 24-h PP is an independent risk factor, which can be taken as an index fro predicting the degree of CHD coronary stenosis.
