What is included in acute coronary syndrome?
The term acute coronary syndrome (ACS) refers to any group of clinical symptoms compatible with acute myocardial ischemia and includes unstable angina (UA), non—ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI).
What are the three acute coronary syndromes?
Non-ST-elevation myocardial infarction (NSTEMI), ST-elevation MI (STEMI), and unstable angina are the three traditional types of ACS.
What are some typical signs and symptoms of acute coronary syndrome?
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.
- Sweating.
How is acute coronary syndrome diagnosed?
Diagnosis
- Electrocardiogram (ECG). Electrodes attached to your skin measure the electrical activity in your heart.
- Blood tests. Certain enzymes may be detected in the blood if cell death has resulted in damage to heart tissue.
Which of the following is the most common symptom of acute coronary syndrome?
The most common symptom of ACS is chest pain. The chest pain may come on quickly, come and go, or get worse with rest. Other symptoms can include: Pain in the shoulder, arm, neck, jaw, back, or belly area.
What is acute coronary syndrome pathophysiology?
The underlying pathophysiology in ACS is decreased blood flow to part of heart musculature which is usually secondary to plaque rupture and formation of thrombus. Sometimes ACS can be secondary to vasospasm with or without underlying atherosclerosis.
What is the difference between coronary artery disease and acute coronary syndrome?
Introduction and definitions On the other hand, CAD is characterized by atherosclerosis in coronary arteries and can be asymptomatic, whereas ACS almost always presents with a symptom, such as unstable angina, and is frequently associated with myocardial infarction (MI) regardless of the presence of CAD (2).
