Have you ever suddenly felt a strange tightness, pain, or shortness of breath in your chest? Or have you seen someone you know do so? These symptoms can sometimes be a sign of a very dangerous heart condition. Acute Coronary Syndrome (ACS) is a common name for several conditions that occur suddenly and are caused by blockages in the arteries that supply blood to the heart.
What is acute coronary syndrome (ACS)?
Simply put, Acute Coronary Syndrome (ACS) is an emergency condition that occurs when the coronary arteries that carry blood to the heart suddenly become blocked, preventing the heart from getting the oxygen it needs. Imagine if something suddenly gets stuck in the pipe that carries water to the water pump in your house. Then the water does not flow properly to the pump. The same thing happens to the heart. This is not a single disease, but rather a combination of three types of heart disease. All of these can be life-threatening, so prompt medical attention is very important.
What types of heart disease fall under ACS?
Okay, so what are the types of heart disease that fall under ACS? There are three main types. These vary depending on where in the heart the blood vessel is blocked, how long it has been blocked, and how much damage has been done to the heart.
1. Unstable Angina: This is when you suddenly experience chest pain or tightness, even when you are at rest. It can feel like someone is squeezing your chest. This is actually a warning sign of a heart attack . It can also happen when previously existing chest pain (stable angina) becomes severe.
2. NSTEMI (Non-ST-elevation myocardial infarction): This is also a type of heart attack. However, in this case , the EKG (Electrocardiogram) test, which measures the electrical activity of the heart, does not show much difference. However, blood tests can detect damage to the heart muscle. Here, the coronary artery is not completely blocked, or if it is blocked, it is only for a short time.
3. STEMI (ST-elevation myocardial infarction): This is the most severe form of heart attack . It can be clearly identified through EKG and blood tests. What happens here is that an artery supplying blood to the heart is completely blocked for a long time, causing damage to a large area of the heart.
Who can develop this ACS condition?
Now you may be wondering who can develop ACS. Actually, anyone can develop it. However, people with certain risk factors are more likely to develop it.
Age and lifestyle:
- Age: Men over 45 years of age and women who have gone through menopause are at higher risk.
- Overweight/obesity.
- Use of drugs such as cocaine.
- Lack of physical exercise.
- Smoking.
- Unhealthy diet (foods high in oil, salt, sugar).
Other medical conditions you have and family history:
- If COVID-19 had broken out.
- Diabetes.
- If anyone in your family has had conditions such as chest pain, heart disease, or stroke.
- High blood cholesterol level.
- High blood pressure (High blood pressure / hypertension).
- If you had high blood pressure, preeclampsia, or diabetes during pregnancy.
Other conditions that show similar symptoms to ACS
But don't assume that ACS is the cause of chest pain. There are several other conditions that can cause similar symptoms to ACS. That's why it's important to get an accurate diagnosis and get prompt treatment . Some of the conditions that can cause similar symptoms include:
- Aortic stenosis.
- Asthma.
- Pulmonary embolism.
- Digestive problems, chronic acid reflux (GERD - Gastroesophageal Reflux Disease) or esophageal spasms.
- Pericarditis.
- Muscle or bone problems.
- Rib fractures.
- Pneumonia.
- Stomach problems such as ulcers.
- Stress, anxiety, or depression.
How common is ACS?
Coronary Artery Disease (CAD) is the most common heart disease in the world and a leading cause of death. So, ACS, a condition related to CAD, kills a large number of people every year. This risk is especially high in men and those with underlying coronary heart disease.
How does ACS occur?
Okay, now let's see how this ACS situation occurs.
Our heart is a muscle. To function properly, it needs a constant supply of oxygen-rich blood. This blood is supplied by the coronary arteries and the small blood vessels that branch off from them.
Sometimes, over time, plaque builds up inside these arteries, narrowing them. This is called atherosclerosis . It's like rust building up in a water pipe over time.
ACS occurs suddenly if this deposited layer of fat (plaque) suddenly bursts or ruptures.
When this happens, a blood clot forms over the broken part. This blood clot narrows the blood flow path even further, or blocks it completely. Then a part of the heart (the myocardium) does not get the oxygen it needs. This lack of oxygen (ischemia) damages the heart muscle. That's when the previously mentioned unstable angina or heart attack occurs.
Very rarely, ACS can also be caused by other reasons:
- Coronary artery embolism is the blockage of a coronary artery by a blood clot, air bubble, or fat particle.
- Coronary artery spasm.
- Spontaneous coronary artery dissection (SCAD).
What are the symptoms of ACS?
Symptoms of ACS can vary depending on where the blood vessel is blocked, the extent of the blockage, your age, gender, and whether you have other medical conditions, such as diabetes.
Often these symptoms come on without warning, even when you're at rest. The most common symptom is chest pain or discomfort (angina) . This can feel like:
- It feels like a pain.
- Like a burn.
- Chest feels heavy.
- Chest tightness.
- Like a push, a squeeze.
- It's like being trapped.
This pain can spread to the left shoulder, down the arm, neck, back, or jaw. However, some people may not experience any chest symptoms.
Other common symptoms:
- Dizziness, lightheadedness, and feeling like you're going to faint.
- Sudden excessive sweating (diaphoresis).
- Tiredness, fatigue.
- Feeling like your heart is beating fast, feeling like your chest is pounding (heart palpitations).
- Pain in the upper abdomen (some may mistake this for indigestion or stomach inflammation).
Women, in particular, are less likely to experience chest symptoms during ACS. They may experience more of these symptoms:
* Nausea or vomiting.
* Pain radiating to the shoulders, neck, abdomen, or jaw areas.
* Difficulty breathing (dyspnea).
If these symptoms persist or worsen, tell your doctor as soon as possible . If you think this could be a heart attack, take an aspirin immediately and go to the nearest hospital emergency department, or call 911.
How is ACS diagnosed?
How do doctors diagnose ACS?
First, you will be examined physically. Then, several blood tests and an EKG (electrocardiogram) will be done. The EKG records the electrical activity of the heart. From these test results, the doctor can determine whether you have a heart attack or unstable angina.
In addition, other tests may be done to rule out other conditions and choose the most appropriate treatment. For example, an exercise stress test or medication stress test increases your heart rate and measures how your heart responds when you work at its maximum.
Imaging studies, such as a CT scan or heart MRI, are also used to obtain detailed images of the heart. Other imaging tests may include:
- Calcium-score screening heart scan.
- Cardiac catheterization.
- Coronary computed tomography angiogram (CCTA).
- Coronary angiogram.
- Echocardiogram.
- Nuclear medicine imaging.
ACS is a medical emergency. If tests confirm that blood flow to the heart is blocked, you will be treated immediately . If you have severe symptoms, such as loss of consciousness, treatment may begin even before a diagnosis is confirmed.
Is there a complete cure for ACS?
There is no cure for ACS. However, early diagnosis and treatment can help prevent further damage to your heart and keep it working as well as possible. Your doctor can tell you more about ways to reduce your risks and prevent complications.
How is ACS treated?
The main goals of treatment for ACS are to reduce pain and restore blood flow and improve heart function as quickly as possible. Your doctor will prescribe treatment based on your specific condition. It usually involves a combination of medications and surgical procedures to open the artery and restore heart function.
What medications can the doctor prescribe for ACS?
The type of medication you receive will depend on your specific condition. In some cases, your doctor may prescribe medication before confirming a diagnosis. These medications may include:
- Anticoagulants or blood thinners, such as aspirin or heparin.
- Angiotensin-converting enzyme (ACE) inhibitors, which lower blood pressure.
- Beta-blockers, which control blood pressure and slow down the heart rate.
- Nitroglycerin, which improves blood flow and reduces chest pain.
- Pain relievers.
- Statins, which lower blood cholesterol levels.
- Thrombolytic medications within the first 12 hours of a heart attack .
Your doctor may also prescribe medications for other related heart problems, such as:
- High cholesterol.
- High blood pressure.
- Irregular heartbeat (Arrhythmia).
Will I need surgery for ACS?
The goal of surgical treatment for ACS is to reopen the blocked artery and restore normal blood flow. Your doctor may recommend treatments such as:
- Angioplasty with stent: Insertion of a small metal mesh (stent) to open the blocked artery.
- Coronary artery bypass surgery (CABG): Creating a new path for blood to flow.
- Percutaneous coronary intervention (PCI): Opening a blocked artery.
How to reduce the risk of ACS?
Adopting a heart-healthy lifestyle can reduce your risk of developing ACS and other cardiovascular conditions. Here are some tips to help you do so:
- Avoid smoking: If you smoke or use nicotine products, ask your doctor about programs and medications that can help you quit smoking.
- Eat a heart-healthy diet: Talk to your doctor or a registered dietitian about a diet that can help you maintain a healthy weight and reduce your risk of heart disease. The Mediterranean and DASH diets are two nutritious diets.
- Limit alcohol consumption: Limit women to one drink per day and men to two drinks per day.
- Manage health problems such as high cholesterol, high blood pressure, diabetes, stress, depression, and anxiety. Your doctor or a mental health counselor can provide support and treatment for this.
- Stay active: Exercise can help you lose weight, improve your fitness, and reduce stress. Talk to your doctor before starting any exercise program.
What is the outlook for ACS status?
The outlook for ACS depends on the specific condition you had, its severity, and the amount of damage to the heart muscle. With timely diagnosis and treatment, as well as lifestyle changes, you can have the best chance of living a healthy life.
Follow your doctor's advice and maintain heart-healthy habits. See your doctor on time, complete any tests your doctor orders, and talk about your long-term care so you can understand what you can do to reduce your risks and prevent complications.
If you have had a heart attack, your doctor may recommend a cardiac rehabilitation program to help you regain strength, reduce health risks, and improve your quality of life.
When should you seek medical advice for ACS?
If you experience symptoms of ACS , seek emergency medical attention immediately . If you experience symptoms of ACS suddenly, or if you think it's a heart attack, go to the emergency department of your nearest hospital, or call 911. Don't waste time!
What information should be provided to the medical team?
When you go to the hospital, the medical team will ask you about your symptoms, such as when they started and how severe they are.
The more details you can provide, the better. Consider these things:
- When did I first feel symptoms?
- What was I doing at that time?
- What are the symptoms?
- How long have they been there?
- Do I have pain? Where is it?
- On a scale of 1 to 10, how much pain do I feel?
- Do I have other medical conditions?
- What medications am I currently taking?
