Ny pathophysiology ny aretim-po, fantatra ihany koa amin'ny hoe infarction myocardial, dia misy ny fikorontanan'ny rà mankany amin'ny ampahany amin'ny hozatry ny fo, mitarika ny fahafatesan'ny sela ao am-po.
Izany dia mitranga noho ny fanakanana ny lalan-drà amin'ny lalan-drà, izay matetika vokatry ny atherosclerosis, toe-javatra iray izay misy ny plaque miorina ao amin'ny lalan-drà.
Misy kolesterola sy tavy, fako avy amin'ny sela, kalsioma, ary fibrine ao amin'ilay takelaka.
Rehefa vaky ny takelaka, dia mety hiteraka fivontosan'ny ra izany, izay mety hanakana ny lalan-drà ary hanakana ny rà be oksizenina tsy hahatratra ny hozatry ny fo.
Io tsy fahampian'ny oksizenina io no mahatonga ny sela hozatra ao amin'ny fo ho faty, ka mitarika ho amin'ny aretim-po.
Miankina amin'ny haben'ny faritra misy ny lalan-dra mikitoantoana sy ny fotoana elaela taorian'ny fanafihana sy ny fitsaboana ny halehiben'ny fahavoazana.
Mety ho fanaintainana na tsy fahazoana aina eo amin'ny tratra, tsy fahampian'ny fofonaina, maloiloy, fanina, ary fanaintainana eo amin'ny sandry, tendany, valanoranony, na lamosiny ny soritr'aretin'ny aretim-po.
Matetika no atao izay hamerenana haingana ny ra ao amin'ny hozatry ny fo, amin'ny alalan'ny fanafody na fitsaboana hafa, toy ny angioplastie sy stenting na fandidiana lalan-dra.
Zava-dehibe ny manamarika fa sarotra ny pathophysiology amin'ny aretim-po ary misy antony maro, anisan'izany ny fototarazo, ny fomba fiainana ary ny tontolo iainana.
Anisan'ny mety hampidi-doza ny aretim-po ny fiakaran'ny tosidra, ny kolesterola avo, ny fifohana sigara, ny diabeta, ny hatavezina, ny tsy fahampian'ny fampihetseham-batana, ary ny aretim-po ao amin'ny fianakaviana.
Mety tsy ho voan'ny aretim-po ianao raha mitandrina tsara.

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.
