摘要
目的 观察精神应激时冠心病患者冠状动脉的舒缩反应。方法 用定量冠状动脉造影观察 2 1例冠心病患者精神应激 (心算 10min)前后冠状动脉内径。结果 精神应激时心率由 ( 78± 16 )增加到 ( 91± 2 2 )次 /min(P <0 0 0 1) ;收缩压由 ( 14 4± 2 2 )上升到 ( 16 6± 2 9)mmHg( 1mmHg =0 133kPa) (P <0 0 0 1) ;舒张压由 ( 93± 8)上升到 ( 10 1± 11)mmHg(P <0 0 5 ) ;心率收缩压乘积由 ( 11 4±3 3)增加到 ( 15 6± 5 7)次 /min·mmHg·10 3 (P <0 0 0 1)。精神应激时冠状动脉病变 ( 2 2处 )段内径由应激前的 ( 1 97± 0 5 7)mm降至 ( 1 6 6± 0 5 2 )mm (P <0 0 1) ,休息 10min后为 ( 1 75± 0 6 2 )mm ,仍明显小于应激前的 ( 1 97± 0 5 7)mm(P <0 0 5 )。结论 精神应激使冠心病患者心率血压明显增高 ,病变段冠状动脉内径明显降低
