"그의 친구가 심장마비로 사망했어요."

Translation: His friend died from a heart attack.

[Zack510737]

To die 죽다
To decease(used in officiallly)사망하다
To pass away(used respectfully ie towards a loved one) 돌아가시다

[Staszek456]

by the way 돌아가시다 means literally 'to go back' or 'return' (돌아가다) with a honorific '시' suffix attached

[KoreanKat9803]

'돌아가시다'가 맞을 뿐만 아니라 '죽다'와 '사망하다'도 꽤 맞아라!

[PIEROS16]

thank you, kind stranger, here's a lingot

[Le_choc]

Is 사망하다 more formal than 죽다?

[my-song]

Yes, think of it as passed away vs died

[AbunPang]

Hm, but if I'm not mistaken (native speakers, please correct me if I am), 사망하다 is quite neutral concerning respect to the deceased person, whereas English "to pass away" is quite respectful. I would expect 사망하다 in formal contexts (it's common in newspaper articles for example). But when speaking of, say, my grandparents or the loved ones of the person I'm talking to, I would choose a more euphemistic expression (probably 돌아가시다, lit. "to go back").

[bnbnb2]

Yeah, you are right(I ama nativv)

[KiwiWangja]

Should "his friend died of a heart attack" not be accepted?

[SvedishPlumber]

Yes

[mxriii]

Why is everyone dying.

[JansonLau1]

심장마비 litterally means the heart went numb isnt it?

[oee16]

마비 (Hanja) means paralysis but is also used to mean numbness/numb, I think.

심장 - heart (organ)

[oee16]

Alternative answer?
His friend lost his life to a heart attack.

[chilamleung]

그의 親舊가 心臟麻痹로 死亡했어요.

[Staffan431948]

Could someone get whoever wrote this an appointment with a psychiatrist? Death, death, death...

[Jeong-JinL]

Death is part of life.

[KoreanKat9803]

대부분의 사람은 그런 거 같아요.

[GeraldMath4]

Interesting that it is "heart attack" instead of "early attack." The notes at the beginning of this section give the English for 心臟 as "early"!

[WooyunChoi]

He died of heart attack died from heart attack is incorrect grammar as die, dies or died goes with the preposition of

[oee16]

Both "die of" and "die from" are correct.

Die of a heart attack implies the heart attack is the direct cause of the person's death.

Die from a heart attack means the heart attack brings about complications which eventually kill the person.
