What Causes Heart Attack? | How to Keep Your Heart Healthy? | Heart Attack Signs and Symptoms
Summary
TLDR心脏病发作是导致全球每年700万人死亡的最为人们所惧怕的心血管疾病之一。心脏病发作的根本原因是供应心脏的冠状动脉被脂肪斑块堵塞,导致心肌缺血。它的典型症状包括胸痛、短促呼吸等。如果发现这些症状,应立即送医。采取健康的生活方式可以降低发病风险。
Takeaways
- ❤️ 人类心脏是负责泵送生命维持血液的生物工程奇迹,但这个重要器官并非不可阻挡。
- 🌍 心脏病发作每年全球夺走约700万人的生命。
- 💔 心脏像所有肌肉一样需要氧气正常工作,它通过冠状动脉获得氧合血。
- 🚫 由于各种原因,冠状动脉的壁上开始形成脂肪沉积或斑块,有时这些斑块可能变硬、变块或发炎,导致部分阻塞。
- ⚠️ 斑块破裂后,身体会立即开始形成血凝块,导致动脉完全阻塞,从而切断对心肌的血液供应,引发心脏病发作。
- 🚑 心脏病发作的常见迹象包括压迫性胸痛或不适,可能蔓延到左臂、颈部、下巴或背部。
- 🔍 对于女性和老年人,持续的疲劳和虚弱可能是心脏不健康的重要迹象。
- 🏥 若发现心脏问题,医生可能会进行心电图或ECG检查,并通过血液测试检查肌肉损伤。
- 💉 在严重情况下,医生可能会通过使用带有气球的细管做血管成形术来清除动脉中的阻塞,或进行搭桥手术。
- 🍏 通过健康饮食、定期锻炼和避免吸烟等生活方式的改变,可以显著降低心脏病发作的风险。
- 🤫 心脏病发作可能突然发生而不被察觉,这称为无声心脏病发作,占所有心脏病发作的五分之一。
Q & A
心脏病发作的常见症状有哪些?
-最常见的症状包括胸部压迫感或不适,可能向左臂、颈部、下颚或背部扩散。有时也会出现其他轻微症状,如气短、冷汗、恶心和头晕。
什么因素会增加心脏病发作的风险?
-高血压、高胆固醇、吸烟、糖尿病、超重和缺乏运动都会增加心脏病发作的风险。
察觉心脏病发作的轻微症状后,应该怎么办?
-如果察觉到上述任何症状且症状无改善迹象,则最好立即带患者前往最近的医院。
医生如何确诊心脏病发作?
-医生可能会做心电图或血液测试来检查心肌损伤。如果确诊,心脏科医生可以进行血管成形术来清除血管堵塞。
怎样预防心脏病发作?
-通过健康生活方式改变可以显著降低心脏病发作的风险,如饮食健康、适度运动、戒烟、充足睡眠和管理压力等。
心脏病发作会导致哪些后果?
-如果不及时救治,心肌细胞因缺氧死亡,心脏会停止跳动,最终可能导致死亡。
心脏病发作的根本原因是什么?
-冠状动脉中脂肪斑块形成并最终完全堵塞动脉,切断心肌供血,导致细胞死亡。
保持心脏健康的关键是什么?
-保持健康的生活方式,如健康饮食、适度运动、管理压力等小事每天都做好,这对心脏健康非常重要。
什么是无症状心脏病发作?
-这指心脏病发作没有任何症状,患者本人都未察觉,这种无症状心脏病发作占所有心脏病发作的五分之一。
为什么心脏如此重要?
-心脏是向全身供血的生命器官,如果心脏停止跳动,血液无法供应,极易导致死亡。

Highlights
心脏病发作是导致全球每年约700万人死亡的最可怕的心血管事件之一
我们的心脏需要氧气才能正常工作,它从称为冠状动脉的血管获取氧合血的供应
由于各种原因,脂肪沉积或斑块开始在这些动脉的壁上形成
如果这个阻塞破裂,你的身体会将其视为任何其他伤害,并在几分钟内开始形成血栓
由于血流被完全阻断,心肌细胞开始死亡,这就导致了心肌梗死
最常见的症状包括压迫性的胸痛或不适,可能会蔓延到左臂、颈部、下颌或后背
医生可能会做一个叫做心电图的测试,来检查心脏的电活动
心脏病医生可以使用一个带气球的薄管进行血管成形术,来清除动脉内的阻塞
在严重的情况下,医生可能会进行旁路移植手术
更好的方法是通过改变生活方式来预防问题,这可以显着降低心脏病发作的风险
每天小小的改变可以对保持心脏健康和强壮产生巨大的不同
心脏病发作可以突然发生,而患者并不知道,这被称为无症状心脏病发作
无症状性心脏病发作占所有心脏病发作的五分之一

oh little kitty you seem to be eating
junk and lacing around too much these
days please get active to help your
heart otherwise such a lifestyle is
known for causing a heart attack really
how well let us explore that by
answering a heartbreaking question what
causes a heart attack zoom
in the human heart a Marvel of
biological engineering is responsible
for pumping life sustaining blood
throughout the body however this vital
organ is not Unstoppable and one of the
most feared cardiovascular events is a
heart attack claiming around 7 million
lives worldwide every year
but what causes it in the first place
you see like all muscles our heart needs
oxygen to function properly it gets the
supply of oxygenated blood from vessels
called coronary
arteries however due to various reasons
fatty deposits or plaque start
developing on the walls of these
arteries at times these fatty pla
can get hardened lumpy or
inflamed causing a partial blockage that
reduces the flow of oxygenated blood if
this block ruptures your body perceives
it as any other injury and within
minutes starts to form blood clots
around it leading to the complete
blockage of the artery as a result blood
flow is cut off to the heart muscles
and oxygen sted cells begin to die
within a few minutes leading to a heart
attack medically known as myocardial
infection if help is not received
immediately things may go downhill as
the heart will stop pumping
blood and in worst case scenario the
person may pass away so it's vital to
understand the war in signs to identify
the lurking threat of a heart attack and
what are
they the most common signs include
crushing chest pain or discomfort that
may spread to the left arm neck jaw or
back at times there are other subtle
signs such as shortness of breath cold
sweats nausea and Li headedness for
women and older people constant
tiredness and weakness can be a major
sign of a weak heart not only that but
certain things make a heart attack more
likely like high blood pressure high
cholesterol smoking diabetes being
overweight and not being active so if
you notice people showing any of the
said symptoms with no sign of
improvement then it's better to
immediately take them to the nearest
hospital the doctor might do a test
called an
electrocardiogram or ECG to check the
heart's electricity and a blood test for
muscle damage if they find a problem the
cardiologist can do an
angioplasty using a thin tube with a
balloon to clear blockages is in the
artery in serious situations doctors
might do bypass surgery they take a
piece of vein from another part of the
body and redirect the blood flow around
the blockage to fix the heart but
remember it's better to prevent Problems
by making Lifestyle Changes which can
significantly lower the risk of a heart
attack yes to keep your heart strong eat
healthy foods like fruits and veggies
play and move around for regular
exercise and stay away from smoking
listen to your body get enough sleep and
manage stress with relaxing activities
like drawing or playing remember small
steps every day can make a big
difference in keeping your heart healthy
and and strong to know more check our
video how your heart
Works trivia time did you know a heart
attack can happen suddenly without a
person knowing it yes this is referred
to as a silent heart attack and these
account for one in five heart
attacks it's sketching time today's
sketch of the day goes to
lohas hope you learn something new today
until next time it's me Dr boox zooming
