慢性冠脉综合征患者急性发作风险与动态血压水平的关系

Relationship between the risk of acute attack and ambulatory blood pressure levels in patients with chronic coronary syndrome

目的探讨慢性冠脉综合征(CCS)患者急性发作风险与动态血压水平的关系。方法选取我院收治的CCS患者81例,对患者随访1年并根据是否急性发作将其分为未发作组(n=47)和急性发作组(n=34)。比较两组24 h血压动态变化及血压分布情况。结果急性发作组的nmSBP、24 h mSBP、nmDBP、24 h mDBP均高于未发作组,SBP、DBP夜间血压下降率均低于未发作组,非杓型发生率高于未发作组(P<0.05)。结论临床可根据患者的24 h动态血压水平预测CCS未来发作风险,并及时调整治疗方案,避免CCS急性发作。

Objective To explore the relationship between the risk of acute attack and ambulatory blood pressure levels in patients with chronic coronary syndrome(CCS).Methods A total of 81 patients with CCS admitted in our hospital were selected and followed up for 1 year,and the patients were divided into non-attack group(n=47)and acute attack group(n=34)by whether the acute attack occurred or not.The 24 h blood pressure dynamic changes and blood pressure distribution of the two groups were compared.Results The levels of nmSBP,24 h mSBP,nmDBP and 24 h mDBP in the acute attack group were higher than those in the non-attack group,and the nocturnal blood pressure decrease rates of SBP and DBP were lower than those in the non-attack group,the incidence of non dipper was higher than that in the non-attack group(P<0.05).Conclusion According to the 24 h ambulatory blood pressure levels of patients,the risk of CCS in the future can be predicted,and the treatment plan can be adjusted in time to avoid the acute attack of CCS in clinic.
