春季适量爬山 谨防运动给心脏惹祸

爬山游玩,锻炼身体,是很多人在春天喜欢做的事。可如果不注意控制运动量,爬山锻炼也会给心脏引发大问题。沙坪坝区的王大爷就在近日一次老年登山会途中突然喘不过气,被紧急送往医院抢救后方才脱离危险。医生说,过大的爬山运动量是导致老人心血管疾病突发的最主要原因。
据第三军医大学新桥医院心内科耿召华博士介绍,冬天过去后,春天温暖的气候比较适宜进行户外爬山活动。但在冬天运动量较小的情况下,人们在爬山时往往不注意控制运动量。有的人爬得太快太猛,心肌耗氧量会明显增加,这种情况下就很有可能因为过度劳累造成头晕、心慌、胸闷、乏力等不适症状,甚至诱发心绞痛,非常危险。另外,山里的气候潮湿,有心血管病史的爬山者易被链球菌感染,造成风心病发作。山上交通不方便,如果出现心血管疾病的其他并发症不及时救治,患者极易发生急性心肌梗死。
近年来,出现心肌梗死并不都是中老年人的事情,年轻患者也要注意保护心脏健康。耿召华博士建议,有冠心病,高血压病史的患者,爬山时应该依据自己身体情况,最好选择海拔不高、山势缓和的小山进行爬山锻炼。爬山的最佳时间应该是下午,因为清晨4点到上午10点,血液为时段性血粘阶段,此时进行爬山等剧烈运动容易发生危险。同时,爬山过程中要根据身体情况适当休息,千万不要一味逞强。随身一定要携带好急救药品,放在好拿出的位置。如果出现急性反应,要第一时间送医院救治,以防出现意外。
