Sa fisiopatologia de un'atacu de coro, connotu fintzas comente infartu de miocàrdiu, ìmplicat s'interrutzione de su flussu de sàmbene a una parte de su mùsculu cardìaccu, batende a sa morte de sas tzèllulas de su coro.
Custu de sòlitu acontesset pro more de s'ostruidura de un'artèria coronària pro unu càmpulu de sàmbene, chi a s'ispissu est su resurtadu de aterosclerosi, una cunditzione in ue sa placa s'ammuntonat in sas artèrias.
Sa placa est fata de colesterolu, sustàntzias grassas, produtos de iscartu tzellulare, càlciu e fibrina.
Cando una placa si nche istratzat, podet fàghere nàschere unu càmpulu de sàmbene, chi podet cungiare s'artèria e impedire a su sàmbene ricu de ossìgenu de segudare su mùsculu cardìacu.
Custa mancàntzia de ossìgenu faghet mòrrere sas tzèllulas de su mùsculu cardìacu, giughende a un'atacu de coro.
S'estensione de su dannu dipendet dae sa mannària de s'àrea frunida dae s'artèria blocada e su tempus intre s'atacu e su tratamentu.
Sos sìntomos de un'atacu de coro podent incrùere dolore o non cumòveru in su pettu, dificultade a respirare, nàusea, vertigine e dolore in sos bratzos, su tzugru, sa barra o sa coa.
Su tratamentu pro un'atacu de coro de sòlitu ìmplicat su riprìstinu de su flussu de sàmbene a su mùsculu cardìacu su prus in presse possìbile, cun meighinas o protzeduras comente s'angioplastia e s'istentzione o s'interventu de bypass a s'artèria coronària.
Est de importu a notare chi sa fisiopatologia de un'atacu de coro est cumplessa e interessat fatores mùltiplos, intre sos cales fatores genèticos, istile de vida e ambientales.
Sos fatores de arriscu pro s'atacu de coro includent pressione arta, colesterolu artu, fumu, diabete, obesidade, mancàntzia de atividade fìsica e un'istòria familiare de maladia de coro.
Manigiare custos fatores de arriscu podet agiudare a reduire sa probabilidade de isvilupare un'atacu de coro.

What is pathophysiology of heart attack?
The pathophysiology of a heart attack, also known as myocardial infarction, involves the disruption of blood flow to a part of the heart muscle, leading to the death of heart cells.
This typically occurs due to the obstruction of a coronary artery by a blood clot, which is often the result of atherosclerosis, a condition where plaque builds up in the arteries.
The plaque is made up of cholesterol, fatty substances, cellular waste products, calcium, and fibrin.
When a plaque ruptures, it can cause a blood clot to form, which can block the artery and prevent oxygen-rich blood from reaching the heart muscle.
This lack of oxygen causes the heart muscle cells to die, leading to a heart attack.
The extent of the damage depends on the size of the area supplied by the blocked artery and the time between the attack and treatment.
Symptoms of a heart attack can include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain in the arms, neck, jaw, or back.
Treatment for a heart attack usually involves restoring blood flow to the heart muscle as quickly as possible, either through medication or procedures such as angioplasty and stenting or coronary artery bypass surgery.
It is important to note that the pathophysiology of a heart attack is complex and involves multiple factors, including genetic, lifestyle, and environmental factors.
Risk factors for heart attack include high blood pressure, high cholesterol, smoking, diabetes, obesity, lack of physical activity, and a family history of heart disease.
Managing these risk factors can help reduce the likelihood of experiencing a heart attack.
