Acute Coronary Syndrome (ACS) is an emergency
condition that occurs when blood flow to the heart suddenly decreases, usually
due to a blockage or narrowing of the coronary arteries. If blood flow to the
heart is reduced, the heart muscle doesn't get enough oxygen. When this
happens, heart tissue cells can be damaged or even die, leading to a heart
attack.
Some common symptoms include:
- Chest pain or discomfort around the chest;
feeling tight, pressured, or burning.
- Pain spreading from the chest to other body
parts, such as the shoulders, arms, upper abdomen, back, neck, and even
the jaw.
- Nausea or vomiting.
- Sudden excessive sweating.
- Feeling a faster heart rate.
- Dizziness.
- Fainting.
If someone experiences similar symptoms, immediate
medical attention is necessary. The goal of treatment, whether with medication
or procedures, is to increase blood flow and prevent complications.
Acute Coronary Syndrome is most commonly caused
by plaque in the coronary arteries. This plaque is made up of fat,
cholesterol, and other substances. Plaque can block blood flow in two ways:
- Plaque gradually builds up, causing the blood vessels
to narrow, which can lead to symptoms.
- Unstable plaque suddenly ruptures, and a blood clot
forms around it, severely narrowing the blood vessel and potentially
causing a complete blockage.
Prevention of ACS is divided into primary and secondary
prevention.
- Primary prevention focuses on preventing ACS from
occurring in the first place. This can be achieved through maintaining
a balanced diet, engaging in regular exercise and physical
activity, also avoiding nicotine use.
- Secondary prevention involves therapy to prevent
further damage and disease progression after someone has already been
diagnosed with cardiovascular disease. Examples of secondary prevention
include regularly taking prescribed medications such as antiplatelet
drugs, antihypertensives, and anti-diabetic medications to regulate the
comorbid condition.
