What Causes Heart Attack? | How to Keep Your Heart Healthy? | Heart Attack Signs and Symptoms

Summary

Une crise cardiaque survient lorsqu'une artère coronaire se bloque, empêchant le sang oxygéné d'atteindre le muscle cardiaque. Cela est souvent causé par des dépôts graisseux qui durcissent et rétrécissent les artères. Les signes comprennent des douleurs thoraciques, un essoufflement et des nausées. Si le blocage n'est pas traité, des cellules cardiaques meurent. On peut débloquer l'artère par angioplastie ou chirurgie de pontage. Mais il vaut mieux prévenir en mangeant sainement, faisant de l'exercice et gérant son stress. Une crise cardiaque peut survenir sans avertissement. Connaître les signes et les facteurs de risque peut sauver des vies.

answering a heartbreaking question what

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

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
