目的探讨原发性高血压患者血压变异性与急性脑梗死的关系。方法选取2013年4—8月我院收治的原发性高血压患者100例,将57例单纯性原发性高血压患者记为A组,将43例合并急性脑梗死患者记为B组,两组患者入院后72 h内均进行24 h动态血压监测,计算两组患者血压变异性指标,包括:24 h收缩压(SBP)、24 h舒张压(DBP)、日间SBP、日间DBP、夜间SBP、夜间DBP的变异系数。结果 A组24 h SBP、24 h DBP、夜间SBP变异系数均低于B组(P<0.05);两组日间SBP、日间DBP、夜间DBP变异系数比较,差异均无统计学意义(P>0.05)。结论原发性高血压患者急性脑梗死的发生与血压变异性有关。
Objective To investigate the relationship between blood pressure variability and acute cerebral infarction in patients with essential hypertension. Methods 100 cases of essential hypertension admitted in our hospital from April to August in 2013 were selected, 57 cases of simple essential hypertension were recorded as group A, 43 cases of patients with acute cerebral infarction were recorded as group B, The ambulatory blood pressure monitoring was performed within 24 hours after admission in both groups, and the indexes of blood pressure variability were calculated in two groups, including 24 h systolic pressure (SBP), 24 h diastolic pressure (DBP), daytime SBP, daytime DBP , Night SBP, nighttime DBP coefficient of variation. Results The coefficient of variation of 24 h SBP, 24 h DBP and night SBP in group A were all lower than those in group B (P <0.05). There was no significant difference in the coefficient of variation of daytime SBP, daytime DBP and nocturnal DBP > 0.05). Conclusion The incidence of acute cerebral infarction in patients with essential hypertension is related to the variability of blood pressure.
