306例高血压病人随机分为气功组(气功加规律服用小剂量降压药)154例和对照组(仅规律服用小剂量降压药)152例。25~30年随访发现:气功组血压稳定率为86.56%,对照组血压稳定率为68.87%,气功组疗效较佳。25~30年随访期间气功组总病死率(22.73%)明显低于对照组(40.79%)。进一步分析发现气功组脑卒中发生率为18.83%,病死率为14.29%,而对照组则分别达33.55%和28.95%,气功组明显低于对照组(P<0.01),14项脑卒中危险和防护因子的多因子回归分析,提示脑卒中的发生与坚持气功锻炼呈负相关。以上结果表明气功锻炼具有预防脑卒中和改善高血压预后的有益作用。
A total of 306 hypertensive patients were randomly divided into Qigong group (qigong plus regular low-dose antihypertensive drug) and control group (regular low-dose antihypertensive drug only) 152 cases. Follow-up from 25 to 30 years showed that the blood pressure stability was 86.56% in the Qigong group and 68.87% in the control group, and the Qigong group was better. The total case fatality rate of Qigong group (22.73%) during 25-30 years follow-up was significantly lower than that of control group (40.79%). Further analysis showed that the stroke rate was 18.83% and the mortality rate was 14.29% in the Qigong group compared with 33.55% and 28.95% in the control group, significantly lower in the Qigong group than in the control group (P <0.01), and 14 in the stroke group Multivariate regression analysis of protective factors suggested that the occurrence of stroke was negatively correlated with insisting on qigong exercise. The above results show that qigong exercise has the beneficial effect of preventing stroke and improving the prognosis of hypertension.
