So what are some of the heart conditions?

Heart conditions encompass a wide range of diseases and abnormalities affecting the heart's structure, function, or rhythm. Each condition has unique causes, symptoms, and treatment options, but early detection and management can significantly improve outcomes.

I’ll provide a detailed overview of the types of heart conditions, their symptoms, and what you need to know to protect your heart health.

Common Heart Conditions

1. Angina

Angina is a symptom rather than a condition itself. It causes chest pain or discomfort when blood flow to the heart is reduced, often due to coronary artery disease (CAD).

Symptoms: Tightness, pressure, or a burning sensation in the chest, sometimes radiating to the shoulders, arms, or neck.
Cause: Typically triggered by physical exertion or stress when the heart muscle doesn’t get enough oxygen-rich blood.

Angina is a warning sign of underlying heart problems and should always be evaluated by a doctor.

2. Arrhythmia

An arrhythmia is an abnormal heart rhythm that causes the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly.

Symptoms: Palpitations, dizziness, fainting, or fatigue.
Cause: Electrical signal disturbances in the heart due to stress, heart disease, or electrolyte imbalances.

3. Atrial Fibrillation (AF)

Atrial fibrillation is a common type of arrhythmia that causes the upper chambers of the heart (atria) to beat irregularly and out of sync with the lower chambers (ventricles).

Symptoms: Heart fluttering, fatigue, and shortness of breath.
Complications: AF increases the risk of stroke and heart failure if untreated.

4. Coronary Heart Disease (CHD)

CHD, also known as coronary artery disease, is caused by the narrowing or blockage of coronary arteries due to plaque build-up (atherosclerosis).

Symptoms: Angina, shortness of breath, or no symptoms until a heart attack occurs.
Complications: If untreated, CHD can lead to heart attacks or heart failure.

For more information on CHD, visit the British Heart Foundation.

5. Heart Attack (Myocardial Infarction)

A heart attack occurs when blood flow to a part of the heart muscle is blocked, usually by a blood clot in a coronary artery.

Symptoms: Chest pain or discomfort, sweating, nausea, and shortness of breath.
Emergency: Immediate medical attention is crucial to minimise damage to the heart.

6. Heart Blocks (Atrioventricular Blocks)

Heart blocks occur when the electrical signals that regulate your heartbeat are delayed or blocked.

Symptoms: Some heart blocks are asymptomatic, while severe ones can cause dizziness, fainting, or fatigue.
Cause: Congenital heart defects, infections, or damage to the heart muscle.

7. Heart Failure

Heart failure happens when the heart is unable to pump blood effectively to meet the body’s needs.

Symptoms: Persistent fatigue, shortness of breath, and swelling in the legs or ankles.
Cause: Conditions like high blood pressure, CHD, or valve disease can lead to heart failure.

8. Stroke

A stroke occurs when the blood flow to part of the brain is interrupted, either by a clot (ischaemic stroke) or a burst blood vessel (haemorrhagic stroke).

Symptoms: Sudden weakness on one side of the body, slurred speech, or loss of coordination.
Cause: Often linked to heart conditions like atrial fibrillation or high blood pressure.

Recognising Common Cardiac Symptoms

Heart conditions can present with a variety of symptoms, including:

Chest Pain: A classic symptom of angina or heart attacks.
Shortness of Breath: Associated with heart failure or valve disease.
Palpitations: Common in arrhythmias like atrial fibrillation.
Swelling: In the legs or ankles, often linked to heart failure.
Fatigue: Persistent tiredness could indicate a struggling heart.

These symptoms should not be ignored and warrant medical evaluation, especially if they occur suddenly or persist.

Diagnosing Heart Conditions

A variety of tests can help diagnose heart conditions:

ECG (Electrocardiogram): Measures the heart’s electrical activity to detect arrhythmias or damage.
Echocardiogram: Uses ultrasound to assess the heart’s structure and function.
Stress Tests: Evaluate how the heart performs under physical exertion.
Blood Tests: Measure cholesterol, glucose, and markers like troponin.
CT or MRI Scans: Provide detailed imaging of the heart and blood vessels.

Managing and Preventing Heart Conditions

While some heart conditions are congenital or genetic, many can be managed or prevented through lifestyle changes:

Healthy Diet: Prioritise fruits, vegetables, whole grains, and lean proteins.
Regular Exercise: Aim for 150 minutes of moderate activity per week.
Quit Smoking: Smoking is a major risk factor for heart disease.
Manage Stress: Practice relaxation techniques like mindfulness or yoga.
Routine Check-Ups: Regular screenings help detect problems early.

When to See a Cardiologist

If you experience any of the following, it’s important to seek specialist care:

Persistent chest pain or discomfort
Unexplained shortness of breath or fatigue
Palpitations or irregular heartbeats
Symptoms of a stroke or heart attack

A cardiologist can provide expert evaluation and recommend the appropriate tests and treatments.
