晨峰血压与心脏事件的影响

The Influence of Morning Blood Pressure Surge for Cardiac Events

摘要: 目的：探讨晨峰血压与心脏事件发生的关系，对心脏事件的早期诊治提供依据。方法：选取2013年1月~2015年1月于我院心内科住院治疗的心脏事件患者72例作为实验组(心脏事件组)；其他疾病患者74例作为对照组(非心脏事件组)。给予动态血压监测，测定其24 h平均收缩压(24 hSBP)、白昼平均收缩压(dSBP)、24 h平均脉压(24 hPP)、夜间平均收缩压(nSBP)、白昼平均舒张压(dDBP)夜间平均舒张(nDBP)和24 h平均舒张压(24 hDBP)。记录每个受检者是否吸烟、肥胖及A型性格。结果：24 hSBP、dSBP、24 hPP、nSBP差异有统计学意义(P < 0.05)。dDBP、nDBP、24 hDBP差异无统计学意义(P > 0.05)；实验组晨峰血压较对照组明显增高，差异有统计学意义(P < 0.05)。采用多因素logistic回归分析得出晨峰血压增高是心脏事件发生的独立危险因子。结论：晨峰血压对心脏事件的发生有重要影响作用。

Abstract: Objective: To investigate the relationship between morning blood pressure surge and the patients with cardiac events and provide basis for early diagnosis and treatment of cardiac events. Methods: 72 patients (cardiac events group) with cardiac events and 74 patients with other diseases (non-cardiac event group) in my hospital are chosen from January 2013 to January 2015. Testing 24-hour ambulatory blood pressure monitoring for every person and recording 24 h systolic blood pressure (24 hSBP), day mean systolic blood pressure (dSBP), the 24 h mean pause pressure(24 hPP), night mean systolic blood pressure (nSBP), day diastolic blood pressure (dDBP), night dias-tolic blood pressure (nDBP), 24 h diastolic blood pressure (24 hDBP), and asked everyone whether he (she) had a-type character, the history of smoking or the obesity. Result: 24 hSBP, dSBP, 24 hPP, nSBP in cardiac events group compared with the non-cardiac event group, P < 0.05, the difference had statistics significance. No statistical difference was detected between the two groups in dDBP, nDBP, 24 hDBP; multiple factor logistic regressive analysis suggested that morning blood pressure surge was the independent risk factor for patients with cardiac events. Conclusion: Our analysis suggested that the patients with cardiac events were influenced significantly by morning blood pressure surge.
