Terminology. Myocardial infarction (MI) refers to tissue death ( infarction) of the heart muscle ( myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [22]

Infarct miocardic. Schema unui infarct miocardic (2) la nivelul vârfului peretelui anterior al cordului (un infarct apical) după obstrucția (1) unei ramuri a arterei coronare stângi (LCA, artera coronară dreaptă = RCA). Infarctul miocardic ( IM) sau Infarctul miocardic acut ( IMA ), numit frecvent și atac de cord, este întreruperea ...
Diagnose myocardial infarct via physical exam and EKG (plus blood test) A diagnosis of myocardial infarction is created by integrating the history of the presenting illness and physical examination with electrocardiogram findings and cardiac markers ( blood tests for heart muscle cell damage ). [1] [2] A coronary angiogram allows visualization ...
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Aug 8, 2023 · Myocardial infarction (MI), colloquially known as “heart attack,” is caused by decreased or complete cessation of blood flow to a portion of the myocardium. Myocardial infarction may be “silent” and go undetected, or it could be a catastrophic event leading to hemodynamic deterioration and sudden death.[1] Most myocardial infarctions are due to underlying coronary artery disease, the ...

A myocardial infarction, also and commonly called a heart attack, happens when a blood vessel in the heart suddenly becomes blocked. Blood vessels carry blood and oxygen. When a blood vessel in the heart gets blocked, blood cannot get to part of the heart. This part of the heart does not get enough oxygen. This is called ischemia.
May 5, 2021 · Myocardial ischemia, also called cardiac ischemia, reduces the heart muscle's ability to pump blood. A sudden, severe blockage of one of the heart's artery can lead to a heart attack. Myocardial ischemia might also cause serious abnormal heart rhythms. Treatment for myocardial ischemia involves improving blood flow to the heart muscle.
