Angina

Gambaran umum

Angina is a type of chest pain or discomfort that happens when your heart muscle doesn’t get enough oxygen-rich blood. It’s not a disease on its own but a symptom of an underlying problem—most commonly narrowed heart arteries. Think of it as a warning signal from your heart, especially during physical activity or stress. The pain often feels like pressure, squeezing, or heaviness in the chest. There are two main types: stable angina (occurs predictably with exertion and goes away with rest) and unstable angina (unpredictable, can happen at rest, and is a medical emergency). Understanding your symptoms helps you take the right steps quickly.

Yes, angina is fairly common, especially in older adults. It affects millions of people worldwide. In the UK, around 2 million people have angina.

Angina primarily affects adults over 55, though it can occur earlier in people with risk factors like smoking, diabetes, high blood pressure, or a family history of heart disease. Men are more likely to develop angina at a younger age, but after menopause the risk for women increases. It is very rare in children and young adults with no heart conditions.

Gejala

Gejala umum

• Chest discomfort: often described as pressure, tightness, squeezing, or a heavy weight on the chest. It is usually behind the breastbone.
• Pain spreading to the arms (often the left arm, but can be both), neck, jaw, shoulder, or back.
• Shortness of breath.
• Feeling tired or dizzy without a clear reason.
• Nausea or indigestion-like feeling, particularly in women.
• The discomfort is often triggered by physical activity, emotional stress, heavy meals, or cold weather, and typically eases with rest.

Gejala pada anak-anak

• Angina is extremely rare in children. Chest pain in children is much more likely to be caused by muscle strain, anxiety, asthma, or gastrointestinal issues. However, any chest pain that is severe, persistent, or accompanied by fainting, trouble breathing, or palpitations should be checked by a doctor.

Gejala pada lansia

• Older adults may have more subtle symptoms—sometimes just fatigue, confusion, or breathlessness rather than clear chest pain.
• They may also find it harder to describe the sensation, so it's important to pay attention to any new, unexplained discomfort.

Penyebab

Penyebab utama

• Coronary artery disease: The most common cause. Fatty deposits (plaques) build up inside the arteries that supply your heart, narrowing them and reducing blood flow. When your heart works harder, it can’t get enough oxygen.
• Coronary artery spasm: In variant angina, the arteries temporarily tighten or spasm, reducing blood flow even without major plaque buildup. This can happen at rest, often at night.
• Severe anemia, heart valve disease, or a very fast heartbeat can also reduce oxygen supply to the heart muscle and cause angina.

Faktor risiko

• Smoking or long-term exposure to secondhand smoke.
• High blood pressure (hypertension).
• High levels of 'bad' cholesterol (LDL) or low levels of 'good' cholesterol (HDL).
• Diabetes or prediabetes.
• Being overweight or obese.
• Not getting enough physical activity.
• A family history of heart disease, especially if a close relative developed it before age 55 (men) or 65 (women).
• Older age—the risk increases as you get older.
• Chronic stress or depression.

Kapan harus ke dokter

Segera temui dokter jika:

• Chest pain that lasts longer than a few minutes, even at rest, or does not ease with your angina medication.
• Pain that spreads to your arm, neck, jaw, or back and feels different from your usual angina.
• You feel sick, sweaty, dizzy, or very short of breath with the pain.
• Your angina pattern is getting worse—more frequent, more intense, or occurring at rest.

Buat janji temu rutin jika:

• You experience recurring chest discomfort during activity that goes away within a few minutes of rest.
• You want to understand the cause of any chest pain and get a proper diagnosis.
• You have risk factors for heart disease and want to discuss preventive steps with your doctor.

Diagnosis

Your doctor will make the diagnosis based on your description of the discomfort, your medical history, a physical exam, and the results of diagnostic tests. They’ll want to know what the pain feels like, when it occurs, what triggers it, and how it goes away. This helps them decide if it’s stable angina, unstable angina, or another condition.

Tes yang mungkin dilakukan

• Electrocardiogram (ECG): A quick, painless test that records the electrical activity of your heart. It can show if you’ve had a heart attack or if the heart is under strain.
• Stress test: You’ll be asked to walk on a treadmill or pedal a stationary bike while your ECG and blood pressure are monitored. Sometimes an imaging scan is done during the test to see blood flow to the heart.
• Blood tests: These check for markers of heart damage, as well as cholesterol, blood sugar, and signs of anemia.
• Echocardiogram: An ultrasound of your heart that shows the structure and pumping function.
• CT coronary angiography: A special X-ray that takes detailed 3D pictures of your coronary arteries to look for narrowing.
• Coronary angiography: A thin tube (catheter) is passed through a blood vessel to the heart, and dye is injected to show blockages on X-ray. This is done in a hospital.

Apa yang diharapkan saat janji temu

Most of these tests are non-invasive and painless apart from a needle stick for blood or contrast dye. A stress test might make you feel tired and a bit breathless, which is normal. Your medical team will explain each step and answer your questions. The whole process may take a few appointments.

Perawatan

The goal of treatment is to relieve or prevent symptoms, improve your quality of life, and lower the risk of a heart attack or stroke. Treatment usually combines lifestyle changes, medications, and sometimes procedures. Your doctor will tailor a plan to your situation and how severe the angina is.

Perawatan mandiri di rumah

• If you feel angina coming on, stop what you’re doing and rest immediately until it passes.
• Take any quick-relief medicine exactly as prescribed by your doctor if you have it.
• Quit smoking—this is one of the most powerful steps you can take. Seek support if needed.
• Eat a heart-healthy diet rich in fruits, vegetables, whole grains, and lean protein, while limiting salt, sugary foods, and saturated fats.
• Maintain a healthy weight.
• Learn to manage stress through deep breathing, meditation, gentle yoga, or talking to a friend or counselor.
• Keep regular appointments with your doctor to monitor your condition.

Perawatan medis

Doctors may prescribe several types of medicines. Some work to prevent angina by lowering the heart’s workload or widening blood vessels; others tackle the underlying causes, like lowering cholesterol or controlling blood pressure. If you have unstable angina or a high risk of heart attack, stronger medicines to prevent blood clots may be used. Always take your medicines as directed and never stop them without talking to your doctor. If lifestyle changes and medicines are not enough, a procedure may be considered.

Kapan operasi dipertimbangkan?

If your coronary arteries are severely narrowed and symptoms limit your daily life, your cardiologist might recommend a procedure to restore blood flow. This could be an angioplasty—where a tiny balloon opens the artery and often a stent (a small mesh tube) is placed to keep it open—or coronary artery bypass grafting, where a blood vessel from another part of your body is used to reroute blood around the blockage. These are major decisions made after thorough testing and discussion.

Hidup dengan kondisi ini

Most people with stable angina lead full, active lives once they learn to recognize and manage their triggers. You’ll develop a routine: taking your medicines, pacing yourself during activity, and knowing when to rest. It can feel worrying at first, but with time, many feel confident and in control.

Tips gaya hidup

• Take all prescribed medications faithfully, even if you feel well.
• Stop smoking completely, and avoid smoky environments.
• Cut down on alcohol—no more than 14 units per week for men and women, spread over several days.
• Practice stress-reduction techniques daily.
• Keep all medical appointments and check-ups.
• Report any change in your symptoms to your doctor promptly.

Diet dan olahraga

A heart-healthy diet is the cornerstone. Aim for plenty of vegetables, fruits, whole grains, and fish, while reducing red meat, processed foods, salt, and sugary drinks. Exercise is important, but always check with your doctor about what level is safe for you. Often, walking, cycling, or gentle swimming are encouraged. Start slowly, warm up before and cool down after, and stop if any chest discomfort occurs. Avoid heavy, rich meals that can trigger angina.

Kesehatan mental dan kesejahteraan emosional

It’s completely normal to feel anxious, down, or scared after being diagnosed with angina. You might worry about having another episode or a heart attack. These feelings can be eased by learning about your condition, talking openly with your healthcare team, and leaning on loved ones. If you feel persistently low or anxious, ask your doctor about talking therapy or support groups. You are not alone, and your emotional wellbeing is just as important as your physical health.

Pencegahan

Many cases of angina can be prevented or delayed. The biggest impact comes from adopting a healthy lifestyle early and managing risk factors. Even if you already have angina, these steps can slow progression and reduce complications.

Program skrining

Regular health checks for blood pressure, cholesterol, and blood sugar are important, especially if you have a family history of heart disease or other risk factors. Catching and treating these conditions early can prevent angina from developing.

Komplikasi

Jika tidak diobati

• Angina that is not well managed can progress to unstable angina, which is a medical emergency.
• The underlying narrowed arteries can lead to a heart attack (myocardial infarction), where part of the heart muscle dies due to prolonged lack of blood supply.
• Over time, reduced blood flow can weaken the heart muscle, potentially causing heart failure or dangerous heart rhythms (arrhythmias).

Prospek jangka panjang

With proper treatment and healthy living, the outlook for most people with stable angina is very good. You can manage symptoms, reduce the chance of a heart attack, and continue doing the things you love. Many live long, healthy lives. The key is early diagnosis, sticking to your plan, and staying connected with your healthcare team. If you ever notice a change, reach out—help is available.
