What is pathophysiology of Heart attack?

['Lalela lelikhasi']

Yini i-pathophysiology yekuhlaselwa yinhlitiyo?

I-Pathophysiology yekuhlaselwa yinhlitiyo, leyatiwa ngekutsi yi-myocardial infarction, ifaka ekhatsi kuphatamiseka kwekuhamba kwengati kuya encenyeni yemsipha wenhlitiyo, lokuholela ekufeni kwetinhlayiya tenhlitiyo.

Loku kuvame kwenteka ngenca yekwandza kwengati emitsanjeni yemitsambo yenhlitiyo, lokuvame kuba ngumphumela wekucina kwemitsambo yemitsambo, simo lapho khona kwakheka khona emabhakede emithanjeni.

Lendvwangu yakhiwa yi-cholesterol, emafutsa, tintfo letisele, icalcium kanye ne-fibrin.

Nangabe i-plaque idzabuka, ingenta kutsi kwakheke ingati, lengavimba lomgogodla futsi ivimbele ingati lenemsoco we-oksijini kutsi ifinyelele emsipheni wenhlitiyo.

Lokushoda kwe-oksijini kubangela kutsi tinhlayiya temsipha wenhlitiyo tife, lokwenta inhlitiyo ishaye.

Bukhulu balomonakalo buye ngekutsi lomgogodla uvale kangakanani kanye nesikhatsi lesendlulile kusukela wahlaselwa kute kube ngulapho selashwa.

Timphawu tekuhlaselwa yinhlitiyo tingafaka ekhatsi buhlungu besifuba, kuphefumula kalukhuni, kukhwehlela, kuba nenhloko lelula kanye nebuhlungu bemikhono, intsamo, umhlatsi nobe umhlane.

Kwelapha sifo senhlitiyo kuvame kufaka ekhatsi kubuyisela ingati kutsi ingene esicutjini senhlitiyo ngekushesha lokukhulu, kungaba ngemitsi nobe ngekuhlindvwa kwemitsambo yenhlitiyo.

Kubalulekile kwati kutsi i-pathophysiology yesifo senhlitiyo iyinkimbinkimbi futsi ifaka tintfo letinyenti, kufaka ekhatsi tintfo letiphatselene netinhlayiya, indlela yekuphila kanye netintfo letiphatselene nemvelo.

Tintfo letibangela sifo senhlitiyo tifaka ekhatsi umfutfo wengati lophakeme, i-cholesterol lephakeme, kubhema, sifo sashukela, kukhuluphala, kungakhoni kutivocavoca kanye nemlandvo wekugula kwenhlitiyo emndenini.

Kunakekela letintfo letiyingoti kunganciphisa ematfuba ekutsi inhlitiyo yakho ihlasele.

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.
