May 16, 2023 · Acute coronary syndrome is a term that describes a range of conditions related to sudden, reduced blood flow to the heart. These conditions include a heart attack and unstable angina. A heart attack happens when cell death damages or destroys heart tissue. A heart attack also is known as a myocardial infarction.
Dec 2, 2022 · Take note of these common signs of an acute coronary syndrome: Chest pain or discomfort, which may involve pressure, tightness or fullness. Pain or discomfort in one or both arms, the jaw, neck, back or stomach. Shortness of breath. Feeling dizzy or lightheaded. Nausea.

Acute coronary syndromes result from a sudden blockage in a coronary artery. This blockage causes unstable angina or a heart attack (myocardial infarction), depending on the location and amount of blockage. A heart attack is death of heart tissue due to lack of blood supply.
Acute coronary syndrome is subdivided in three scenarios depending primarily on the presence of electrocardiogram (ECG) changes and blood test results (a change in cardiac biomarkers such as troponin levels): ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), or unstable angina.
Acute coronary syndromes include. Unstable angina. Non–ST-segment elevation myocardial infarction (NSTEMI) ST-segment elevation myocardial infarction (STEMI) These syndromes all involve acute coronary ischemia and are distinguished based on symptoms, ECG findings, and cardiac biomarker levels.
