“37大但人文艺术yongyuxun8998”寒冬至心脑血37大但人文艺术yongyuxun8998管“怕冷” 专家支招儿保健康

  中新37大但人文艺术yongyuxun8998网上海12月26日电 (陈静 37大但人文艺术yongyuxun8998何佳楠)近期,上海气温急剧下降。低温和寒潮之下,心脑血管疾病的发病率会增加。 研究发现,不少心血管疾病患者死因与天气变化相关,冬季心血管病死亡率比夏季高41%。

  “冬季是脑血管意外高发期。”冬雷脑科医院神经外科主任王威26日对记者表示,随着年龄的增长,人体血管的弹性会逐渐减弱,尤其在寒冷的天气,血管遇到冷刺激就会收缩,导致血压升高。对于本身就有高血压的人群来说,动脉瘤破裂的风险就会增加。

  据介绍,脑动脉瘤是脑血管壁上的异常膨出。脑动脉壁先天性薄弱,在血流不断冲击下形成局部膨出,就像血管壁上吹起的一个气泡。这个“气泡”是藏在颅内的一颗“不定时炸弹”:当患者出现精神紧张、情绪激动、劳累、用力举重物、上楼等时,均可诱发血压增高而导致的脑动脉瘤破裂,造成蛛网膜下腔出血,严重者还会出现脑内出血,患者随时会出现生命危险。

 37大但人文艺术yongyuxun8998 王威分享了一个病例,本月,一名老人在晨练中突感剧烈头痛、全身乏力,随即失去意识并跌坐在地。在医院,经CT扫描后,医生诊断患者出现蛛网膜下腔出血并伴有脑室积血,进一步的血管造影检查后,医生确认其脑动脉瘤破裂,情况极为严重。经过动脉瘤介入栓塞治疗、开颅脑室外引流手术,患者最终苏醒。

  冬季室内外温差较大,频繁的温度变化会使人体血管受到较大的波动压力,加剧动脉瘤破裂的可能性。对此,王威提醒民众,注意保暖、饮食均衡、适量运动,同时保持良好心态,定期检查、按时吃药。

  这位专家表示,冷风嗖嗖的时候,老人尽量少出门,免得血管一收缩,心脏和大脑供血不足;温差大的时候,记得衣服要穿得合适,特别是头和手,别让它们冻着。冬天少吃点高热量的食物,别让胆固醇和血脂往上飙;多吃点肉、饭、水果和蔬菜,让血管保持健康。王威提醒,冬天,老人每天动一动,散散步或者打打太极,血液循环就会好很多。早上冷的时候别太剧烈运动,等太阳出来,气温升高了再出去活动。他提醒民众定期去医院检查,特别是有心脑血管疾病的朋友,记得按时吃药,别自己随便改药量和频率。

  做好这些,冬天罹患心脑血管疾病的风险就能大大降低。这位专家表示,万一觉得不对劲,比如脸歪了、走路不稳或者说话困难,赶紧找医生帮忙。(完)
