摘要 目的研究原发性醛固酮增多症(PA)高血压患者的动态血压特点。方法选取2013年1月至2016年12月在首都医科大学附属北京安贞医院确诊且临床资料齐全的123例PA高血压患者为观察组;以性别、年龄、病程匹配同期临床资料齐全的124例原发性高血压(PH)患者为对照组。比较观察组和对照组平均血压水平、血压变异性、昼夜节律等动态血压参数;观察组再按病理类型和病变范围进行分组,比较各组PA高血压患者的动态血压参数。结果观察组与对照组的比较:①血压水平:观察组的24h平均收缩压、白昼平均收缩压、夜间平均收缩压(nSBP)、24h平均压舒张压(24hDBP)、白昼平均舒张压、夜间平均舒张压(nDBP)均明显高于对照组[(135±15)mmHg(1mmHg=0.133kPa)比(127±15)mmHg、(137±14)mmHg比(129±15)mmHg、(132±16)mmHg比(122±17)mmHg、(86±11)mmHg比(79±11)mmHg、(87±10)mmHg比(81±11)mmHg、(81±10)mmHg比(75±12)mmHg](P〈0.01);②血压变异性:观察组24h舒张压变异系数明显低于对照组,差异有统计学意义[10.4(8.9,16.0)比10.6(9.7,13.0)](P〈0.05);③昼夜节律:观察组的nSBP下降率明显低于对照组[3.6%(0.O%,8.5%)比6.1%(0.9%,10.0%)](P〈0.05),但nDBP下降率与对照组差异无统计学意义(P〉0.05);④心率:2组24h、白昼、夜间平均心率差异均无统计学意义(均P〉0.05)。不同病理类型和范围PA高血压患者比较①血压水平:左侧腺瘤组、右侧增生组的24hDBP、nDBP明显低于右侧腺瘤组,差异有统计学意义[(85±10)、(82±10)mmHg比(90±12)mmHg,(81±10)、(76±10)mmHg比(86±9)mmHg](P〈0.05),各组间其他血压水平参数差异无统计学意义(P〉0.05);②血压变异性:各组间血压变异性差异无统计学意义(P〉0.05);③昼夜节律:各组间血压昼夜节律参数差异无统计学意义(P〉0.05);④平均心率:各组间24h、白昼、夜间平均心率差异无统计学意义(P〉0.05)。结论PA高血压与PH动态血压参数存在明显差异;病理类型及范围对PA高血压患者动态血压也有一定影响。 Objective To investigate characteristics of ambulatory blood pressure in hypertensive patients with primary aldosteronism(PA). Methods From January 2013 to December 2016, 123 hypertensive patients with PA were included as observation group in Beijing Anzhen Hospital, Capital Medical University; 124 patients with primary hypertension(PH) ( sex, age and disease course matched) were included as control group. Blood pressure, blood pressure variability and circadian rhythm were analyzed. Results Comparisons between observation group and control group showed: (1) 24 h systolic blood pressure, daytime systolic blood pressure, nocturnal systolic blood pressure(nSBP), 24 h diastolic blood pressure(24 hDBP), daytime diastolic blood pressure and nocturnal diastolic blood pressure(nDBP) in observation group were significantly higher than those in control group [ ( 135 ± 15) mmHg vs ( 127 ± 15) mmHg, ( 137 ± 14) mmHg vs ( 129 ± 15) mmHg, ( 132 ± 16) mmHg vs ( 122 ± 17)mmHg, (86±11)mmHgvs (79±11)mmHg, (87 ±10)mmHgvs (81 ±11)mmHg, (81 ±10)mmHg vs (75 ± 12)mmHg ] (P 〈 0. 01 ). (2) 24 hDBP coefficient variation in observation group was significantly lower than that in control group[ 10. 4(8.9,16. 0) vs 10. 6(9.7,13.0) ] (P 〈0. 05). (3) the decline rate of nSBP in observation group was significantly lower than that in control group[ 3.6% (0. 0% ,8.5% ) vs 6. 1% (0. 9% , 10. 0% ) ] ( P 〈 0. 05 ) ; the decline rate of nDBP had no significant difference between groups ( P 〉 0. 05 ). (4) 24 h heart rate (HR) , daytime HR and nocturnal HR had no significant differences between groups (P 〉 0. 05 ). Comparisons among PA patients with different pathological types and lesion range showed: (1) 24 hDBP and nDBP in left side adenoma group and right side hyperplasia group were significantly lower than those in right side adenoma group [ (85 ± 10),(82 ± 10)mmHg vs (90 ± 12)mmHg; (81 ± 10),(76 ± 10)mmHg vs (86 ±9)mmHg] (P 〈0. 05). (2) Parameters of blood pressure variability showed no significant differences among groups (P 〉 0. 05 ). (3) Parameters of circadian rhythm showed no signifieant differences among groups ( P 〉 0. 05 ). (4) 24 h HR, daytime HR and nocturnal HR had no signifieant differences among groups ( P 〉 0. 05 ). Conclusions There are differenees of ambulatory blood pressure parameters between hypertensive patients with PA and patients with PH. Pathological types and range of PA also have influenees on ambulatory blood pressure.
