Abstract:
Objective To explore the relationship between the level of morning blood pressure surge (MBPS) and High-sensitivity C-reactive protein( hs-CRP) in acute coronary events among old patients and to evaluate their clinical value. Methods One hundred and twenty - three patients with coronary disease were divided into two groups, each of which was old myocardial infarction(OMI, n = 55) and old myocardial infarction with acute cardiovascular syndrome (OMI + ACS, n =68). The control group includes the patients without coronary disease( n =50). The patients who have infection, malignant tumors, liver and kidney dysfunction, blood diseases, valvular heart diseases, congenital heart diseases, aortic dissection,secondary hypertension were not included. All groups were received 24 hours ambulatory blood pressure monitoring to calculate MBPS and the determination of hs-CRP in serum. Results Compared with each two groups, the levels of MBPS and hs-CRP in OMI group were significantly higher than those of the control group (0. 01 ＜ P ＜0. 05) , and had more significance in the other groups ( P ＜0.01). The levels of MBPS and hs-CRP had positive relationship in coronary events in the elderly ( r =0. 76, P ＜0. 01) . Conclusion The level of MBPS is positively correlated with serum hs-CRP which is one of key risk factors of inflammatory reactions by impairing vessels in body. The two factors both play important roles in the occurrence and the development of coronary events among old patients. They both have important clinical value in recurrent acute coronary events among old patients.
