What is pathophysiology of Heart attack?

['Phulaphula eli phepha']

Yintoni i-pathophysiology yesifo sentliziyo?

Ipathophysiology yesifo sentliziyo, ekwabizwa ngokuba yi-myocardial infarction, ibandakanya ukuphazamiseka kwegazi eliya kwinxalenye yesihlunu sentliziyo, nto leyo ekhokelela ekufeni kweeseli zentliziyo.

Oku kwenzeka ngenxa yokuvaleka kwemithambo yegazi ngenxa yokuqina kwegazi, nto leyo edla ngokubangelwa kukuqina kwemithambo yegazi, imeko apho i-plaque ihlangana khona kwimithambo yegazi.

Le plaque yenziwe ngecholesterol, amafutha, inkunkuma eyenziwa ziiseli, ikhalsiyam nefibrin.

Xa i-plaque iqhuma, inokubangela ukuba kuvele igazi eliqingqiweyo, elinokuvala umthambo lize lithintele igazi elino-oksijini ukuba lingafiki kwisihlunu sentliziyo.

Oku kunqongophala kweoksijini kubangela ukuba iiseli zemisipha yentliziyo zife, nto leyo ekhokelela kwisifo sentliziyo.

Umlinganiselo womonakalo uxhomekeke kubukhulu bommandla ongena kuwo umthambo ovalekileyo nexesha eliphakathi kokuhlaselwa nokunyanga.

Iimpawu zokuhlaselwa sisifo sentliziyo zinokubandakanya iintlungu okanye ukungakhululeki esifubeni, ukuphefumla kancinci, isicaphucaphu, ukuziva unesiyezi, iintlungu ezingalweni, entanyeni, emhlathini okanye emqolo.

Unyango lwesifo sentliziyo ngokuqhelekileyo luquka ukubuyisela igazi kwisihlunu sentliziyo ngokukhawuleza kangangoko kunokwenzeka, mhlawumbi ngokusebenzisa amayeza okanye iinkqubo ezinjengokufakelwa iangioplasty ne-stent okanye utyando lokuthintela imithambo.

Kubalulekile ukuqaphela ukuba i-pathophysiology yesifo sentliziyo inzima kwaye ibandakanya izinto ezininzi, kuquka imizila yemfuza, indlela yokuphila nezinto ezibangele imeko-bume.

Izinto ezibangela ukuba umntu abe nesifo sentliziyo ziquka uxinzelelo lwegazi oluphezulu, icholesterol eninzi, ukutshaya, isifo seswekile, ukutyeba kakhulu, ukungawenzi umthambo nokuba nesifo sentliziyo entsatsheni.

Ukulawula ezi zinto zinokubangela isifo sentliziyo kunokunceda ekunciphiseni amathuba okuba nesifo.

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.
