Abstract：Objective To investigate the correlation between ambulatory pulse pressure indexes (APPI) and coronary artery disease (CHD) in patients with hypertension. Methods The hypertensive patients (n=355) with coronary angiography (CAG) were chose from Apr. 2010 to Apr. 2013 and then divided into CHD group (n=237) and non-CHD group (n=118) according to CAG resutls. All patients were given 24-hour ambulatory blood pressure monitoring. The changes of SBP, DBP and pulse pressure (PP) were recorded and mean pressure [MBP=(SBP+DBP)/2] and PP index (PPI=PP/SBP) were calculated. The correlation between the above mentioned indexes and coronary artery lesions was analyzed. Results The levels of PP and APPI were higher in CHD group than those in non-CHD group [PP:(77.8±8.7) mmHg vs. (64.7±7.6) mmHg;APPI:(0.52±0.08) vs. (0.45±0.10) , P<0.05]. In CHD patients, the higher APPI value, the more severe coronary artery lesions (P<0.01). The results of Logistic analysis showed that APPI (OR=1.39), PP (OR=1.23) and SBP (OR=1.27) were risk factors of CHD (all P<0.01). Conclusion APPI value can be used for predict the severity of coronary artery lesions in patients with hypertension.
