STEMI is a medical term used to describe a type of heart attack. It stands for ST-elevation myocardial infarction. The correct spelling of this term is important to ensure proper medical treatment. When pronounced using IPA phonetic transcription, it is spelled "stɛmi". The "st" sound is followed by the short "ɛ" sound, then the "m" sound and finally the long "i" sound. Understanding the IPA transcription helps in accurately communicating medical terms and avoiding confusion in healthcare settings.
STEMI stands for ST-segment elevation myocardial infarction. It is a medical emergency that occurs when there is a complete blockage of one of the major arteries supplying blood to the heart muscle. This obstruction typically occurs as a result of a blood clot forming on the surface of an atherosclerotic plaque within the coronary artery.
The term "ST-segment elevation" refers to a characteristic pattern seen on an electrocardiogram (ECG), which is a test that records the electrical activity of the heart. In a STEMI, the ST segment on the ECG is visibly elevated above the baseline, indicating a significant disruption in blood flow to the heart muscle.
A myocardial infarction, also known as a heart attack, is the death of a part of the heart muscle due to prolonged lack of blood supply. In the case of a STEMI, the complete blockage of the artery deprives the myocardium of oxygen and nutrients, leading to irreversible damage and potentially life-threatening complications if not promptly treated.
Immediate medical intervention is crucial in the management of a STEMI. Treatment typically involves restoring blood flow to the affected artery through a procedure known as percutaneous coronary intervention (PCI) or, in some cases, by administering clot-dissolving medications called thrombolytics. Prompt reperfusion therapy aims to minimize the size of the heart attack and improve the patient's prognosis. Post-treatment, patients require ongoing medical management, lifestyle changes, and secondary prevention strategies to reduce the risk of future cardiac events.
