Angina is a heart disease that makes coronary arteries narrow. This leads to chest pain and discomfort. There are two main types: stable and unstable angina. The first is predictable, while the latter comes unexpectedly. They both cause chest pain, tightness, and can make you feel pressure for minutes.
Treating angina involves medicines, lifestyle changes, or surgeries like angioplasty. Now, stem cell therapy is becoming a new way to help. It aims to repair the heart’s damaged tissues and make the heart work better in people with angina.
Key Takeaways:
- Angina is a heart disease characterized by chest pain and discomfort.
- Symptoms of angina include chest pain, chest tightness, and pressure.
- Treatment options for angina include medications, lifestyle changes, and medical procedures.
- Stem cell therapy shows promise in regenerating damaged heart tissue and improving heart function.
- Early diagnosis and appropriate treatment play a crucial role in managing angina effectively.
What is Angina?
Angina causes chest pain when the heart doesn’t get enough oxygen-rich blood. It happens because the coronary arteries are narrowed or blocked. This reduces blood flow to the heart. There are several types of angina, including stable, unstable, and variant angina.
Stable angina is common and arrives with physical effort or stress. Its occurrence is expected, and it usually goes away with rest or medication. Unstable angina, however, is unpredictable and more severe. Its symptoms can show up at rest or with little exertion, warning of a possible heart attack. Variant angina, or Prinzmetal’s angina, is infrequent. It happens at rest due to coronary artery spasms.
Angina’s symptoms may differ but often include chest pain, chest tightness, breathlessness, and tiredness. The pain feels like a squeezing, with pressure, and may spread to the arms, shoulders, neck, jaw, or back. These episodes usually last a few minutes. They might be set off by stress or activity.
Angina itself isn’t a heart attack. But it could signal an underlying heart problem. If you feel chest pain, getting medical help is crucial. This is how you can find out the cause and get the right treatment.
Types of Angina
Angina mainly falls into three types:
- Stable Angina: It shows up with physical or emotional stress and is usually predictable. Rest or medicine can make it better.
- Unstable Angina: This type is more severe and less predictable. Symptoms might come on without exertion and could indicate a heart attack.
- Variant Angina: Also called Prinzmetal’s angina, it’s rare and causes pain at rest. Spasms in the coronary arteries are behind it.
Symptoms of Angina
Frequent angina symptoms include:
- Chest pain or discomfort
- Chest tightness
- Shortness of breath
- Fatigue
The chest pain often feels like a squeezing, and you may feel it in the arms, shoulders, neck, jaw, or back. These signs hint at angina and last only for minutes. They might be from stress or physical activity.
Knowing angina’s symptoms and acting when you first feel them is important. A doctor can check your symptoms, do tests, and suggest the best way to treat your angina.
Causes of Angina
The main cause of angina is coronary artery disease. This happens when the blood vessels that give the heart oxygen-rich blood are blocked. Such a block can cause chest pains. Other lifestyle factors and risk factors also add to angina’s development.
Smoking is a big risk for angina and heart disease. The bad stuff in tobacco harms blood vessels. This leads to blocked arteries. Smoking also lowers the blood’s oxygen, damaging the heart even more.
High blood pressure is another common risk. It strains both the heart and the blood pipes. This strain can lead to angina over time.
High cholesterol in the blood is not good either. High LDL or “bad” cholesterol makes artery walls thick. This blocks blood flow to the heart, causing angina symptoms.
Diabetes also raises the risk for angina. High blood sugar damages blood vessels. It usually comes with obesity and high blood pressure, making angina even more likely.
Lifestyle Factors
Living unhealthily can be bad for your heart. Being too heavy or sitting too much can cause heart and artery problems. These lifestyle choices can lead to angina.
Family history and genetics matter too. If heart disease runs in your family, you might face a higher risk. Also, men over 45 are generally more at risk for angina.
In short, angina comes from coronary artery disease, which blocks heart blood vessels. But smoking, high blood pressure, high cholesterol, diabetes, obesity, no exercise, and family heart problems can make angina worse. It’s good to know these risks and change your lifestyle. This can lower your risk of angina and make your heart healthier.
Angina Symptoms
Angina symptoms can change how you go about your day. The most common one is chest pain. It feels like someone is squeezing you or putting pressure on your chest. This pain may spread to your arms, shoulders, neck, jaw, or back.
People with angina might also feel their chest is tight. It’s like someone is squeezing around their chest.
Angina can also cause you to feel out of breath. It might be hard for you to catch your breath at times.
Feeling tired a lot is another sign of angina. Even when resting, you might not feel like you have much energy.
Other symptoms could include feeling dizzy, nauseous, or sweating too much. These might happen when you’re active or under stress.

Angina Treatment
The aim of treating angina is to lower symptom frequency and severity. It also looks to improve life quality and prevent issues. Treatment includes meds, changes in lifestyle, and medical steps.
Medications
Doctors often prescribe meds for angina to lessen symptoms and better heart blood flow. Common meds are:
- Angina medications like nitroglycerin ease chest pain and boost heart blood flow.
- Beta-blockers lower heart rate and blood pressure, reducing heart stress.
- Calcium channel blockers expand blood vessels, improving blood flow.
- Aspirin keeps blood clots at bay, cutting heart attack risk.
Lifestyle Changes
Changing up your life plays a key part in angina care and heart health enhancement. These lifestyle tweaks can greatly cut symptoms and boost well-being:
- Stop smoking to better heart health and lower heart complication risks.
- Keep a healthy weight with a good diet and exercise.
- Eat a heart-friendly diet that’s low in bad fats, cholesterol, and salt.
- Get moving regularly, like with walks or swims, for better heart fitness.
- Handle stress with relaxation or activities such as yoga or meditation.
Medical Procedures
In some situations, medical procedures might be needed for angina and to enhance heart blood flow. These steps include:
- Angioplasty is a not-so-invasive method where a catheter with a balloon opens up blocked arteries to restore blood flow.
- Coronary artery bypass surgery sets up a ‘detour’ from other blood vessels, letting blood flow around blockages and to the heart better.
Using the right meds, living healthily, and possibly having medical procedures like angioplasty or bypass surgery, people with angina can well manage their condition. They can cut symptoms and better their life’s quality.
Angina Diagnosis
To diagnose angina, a doctor checks your medical history, does a physical exam, and may order tests. This full checkup finds the correct cause of your chest pain. It’s a thorough way to know what’s really going on.
Medical History
First, the doctor will look at your health story. They ask about your chest pains – how often, how bad, what makes it better or worse. Tell them about any health issues or family history of heart problems. This info is key to a precise diagnosis.
Physical Examination
The next step is a checkup. The doctor listens to your heart, measures your blood pressure, and looks for signs of heart trouble. A complete physical exam can spot clues that suggest angina. This exam helps find any signs of heart disease.
Diagnostic Tests
Tests might be needed to confirm angina. They check your heart’s activity, blood flow, and the state of your arteries. Tests often used are:
- Electrocardiogram (ECG): This test checks your heart’s electric patterns. It can find heart rhythm issues or signs of angina. It’s a basic test for heart problems.
- Stress Test: It’s a kind of exercise test. You walk on a treadmill while being monitored. This test sees how your heart reacts to movement and if it triggers angina symptoms.
- Coronary Angiography: For this X-ray test, a dye is injected into your arteries. It shows any blockages or narrowings. This test gives clear pictures of your heart’s blood flow to help plan treatment.
All the data from your history, exam, and tests helps your doctor diagnose angina. They build a treatment plan just for you. This care is designed to deal with your specific case.
