摘要 目的通过观察血清胱抑素C与高血压患者心肌纤维化及左室舒张功能的相关陛,探讨胱抑素C对高血压心肌纤维化和心功能的影响。方法测定100例初发原发性高血压患者(高血压组)和50例健康者(对照组)的血清胱抑素C、Ⅰ型前胶原(PCⅠ)、Ⅲ型前胶原(PCⅢ)和心功能等指标,并进行统计学分析。结果高血压组血清胱抑素C[(2.11±0.95)mg/L]、PCⅠ[(76.87±20.72)μg/L]、PCⅢ[(144.66±29.67)μg/L]、左室舒张末期内径(LVEDD)[(47.12±9.78)mm]、E波减速时间(EDT)[(159.68±26.88)ms]和收缩压[(148.86±22.32)mmHg(1mmHg=0.133kPa)]显著高于对照组[分别为(1.04±0.49)mg/L、(38.92±11.65)pg/L、(64.31±15.19)μg/L、(45.31±8.36)mm、(142.45±21.76)ms、(125.75±15.84)mmHg](P〈0.05),二尖瓣口舒张早期流速峰值/舒张晚期流速峰值(E/A)(0.77±0.53)显著低于对照组(1108±0.44)(P〈0.05)。偏相关分析表明,高血压患者的血清胱抑素C与PCⅢ、PCⅠ和LVEDD呈显著正相关(r=0.577、0.514、0.479,P〈0.05);与E/A呈显著负相关(r=-0.406,P〈0.05)。结论胱抑素C可能通过促使心肌纤维化和损害左室舒张功能等途径参与高血压的病理生理过程。
