心脑血管急症身体会有哪些预警?这些症状要警惕

气温骤降诱发血管收缩与血压升高,专家提醒识别预警信号并做好科学防护

Quick Look

冷空气来袭导致气温下降,心梗、脑梗进入高发期。专家指出寒冷刺激引起血管收缩、血压升高及血小板功能增强,可能诱发斑块破裂和缺血事件。文章介绍了晨练、泡脚、喝水、进补等日常习惯的血管风险,以及心梗、脑梗的典型预警信号和专家建议的防护措施。

Why It Matters

冷空气来袭导致气温明显下降,心梗、脑梗进入高发期。研究显示,气温每降低1摄氏度,心梗风险升高2%。冬季昼夜温差大、室内外冷热交替,寒冷刺激会直接引起血管收缩、痉挛。

随着冷空气来袭,气温下降明显,心梗、脑梗进入了高发期。研究显示,气温每降低1摄氏度,心梗风险升高2%。

冷热刺激之下,血管会发生怎样的变化?为什么冬季更容易诱发心脑血管急症?

专家介绍,冬季昼夜温差大、室内外冷热交替,寒冷刺激会直接引起血管收缩、痉挛。健康血管弹性好,调节能力强;但对于存在动脉硬化、血管斑块的人群,血管收缩不仅会造成供血不足,还可能诱发斑块破裂、脱落,堵塞血管,进而引发心梗、脑梗。

北京大学人民医院神经内科主任医师 刘尊敬:气温骤降,会诱发交感神经兴奋,血压是升高的。天气突然降温,可能会导致患者体内的血小板功能得到提升,也就是我们说的凝血功能可能更强一些。从这个角度来讲,也是诱发缺血事件的一个原因。温度突然骤降,内皮细胞的功能可能也会受到影响,包括炎性反应增加,这样就让一些斑块的不稳定性增加。斑块的不稳定性同样会带来缺血性心脑血管病事件的增加。

这些日常习惯暗藏血管风险

专家提醒,不少心脑血管急症看似突然发作,其实是长期不良习惯叠加寒冷刺激共同诱发的。

大清早外出晨练、盲目高温热水泡脚、喝水过少、进补过量,这些很多人习以为常的做法,背后藏着不小的隐患。

不少老年人有早起晨练的习惯,清晨日出前后往往是一天当中气温最低的时段,低温会直接刺激血管收缩,大幅升高心梗、脑梗的发病风险。还有人觉得热水泡脚能够活血养生,可对于本身存在下肢血管缺血、患有糖尿病的人群来说,高温泡脚不仅不养生,反而会加重肢体缺血,暗藏危险。

秋冬出汗变少,很多人喝水不足,血液黏稠度上升;还有部分人群冬季盲目进补,血脂快速波动,同样会加重血管负担。

读懂身体求救信号

识别心脑血管急症预警

心梗、脑梗发病常常十分凶险,很多人误以为心梗一定伴随着剧烈胸痛,脑梗一定会剧烈头痛,实际上血管急症的预警信号复杂隐蔽,不同部位发病表现各不相同。

那么如何快速识别,把握救治时机,日常如何做好科学防护,降低冬季心脑血管急症的发病风险呢?

北京大学人民医院神经内科主任医师 刘尊敬:突然发生心肌梗死时,有的病人胸骨后的疼痛很明显,并且这种疼痛可以放射到背部、肩部,甚至颜面部。也有一部分心肌梗死的患者,症状不是那么典型,有的感到的是胸前区的不适感,胃部区域的不适感,或者疲乏乏力。一旦有不适,就要及时就诊。

和心梗信号不同,脑梗发作有一套辨识度很高的典型表现,记住这些特征,就能快速识别中风风险。

首都医科大学附属北京朝阳医院血管外科主任医师 郭建明:脑梗有几个典型的表现,一个是突然发现说话不利落了。或者是胳膊腿活动灵活性出问题了,比如拿筷子夹东西,突然发现夹不稳了。另外就是突然发现脸和嘴角开始斜了,往一侧偏。

识别预警信号、及时送医是救治的关键,日常做好科学防护,同样能降低冬季心脑血管急症的发病风险。

首都医科大学附属北京朝阳医院血管外科主任医师 郭建明:保暖是第一位的。对于老年人来说,要适度锻炼,一定要量力而行,过度锻炼也有可能对心脑血管造成负担。还有就是要及时按规律吃药。如果出现了高血压、高血糖,一定要积极地去控制它。另外要戒烟,因为抽烟对血管的伤害是非常大的。还有就是要定期体检,60岁以上每年要做脑血管和颈动脉的超声。

"Free Talk" The cell phone that I dare not mute is also in our house

The author tells the story of his mother, who is disabled and bedridden with dementia, and has an Indonesian caregiver at home, but she has to rely on mobile phone translators because of the language barrier. The retired father, who is over 70 years old, is responsible for driving to and from rehabilitation, accompanying him to medical appointments, communicating with doctors and sorting out medications. The author talks to his mother every day. The article points out that the long-term care system provides services, but families are faced with a life that continues to operate every day. Coordination, waiting, communication and companionship cannot be included in the service hours, but they are also part of care.
