One of the main causes of death worldwide is still heart disease. Your ability to manage your symptoms and follow dietary guidelines can have a big impact on your heart health.

What do we need to know about heart disease, and how can we protect our heart?

In this comprehensive guide, we will cover all the important features of heart disease, from identifying symptoms to putting heart-healthy diets and management advice into practice. This comprehensive guide offers helpful information to help you maintain a healthy heart, regardless of whether your goal is to prevent heart disease or manage an existing condition.

What is heart disease, and how does it affect health?

Heart disease encompasses a range of conditions that affect the heart’s structure and function. The most common types include coronary artery disease, heart failure, arrhythmias, and valvular heart disease. Understanding these different types is essential for recognising symptoms and implementing effective management strategies.

Coronary Artery Disease (CAD)

Coronary artery disease is the most prevalent type of heart disease. It occurs when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to the buildup of cholesterol and fatty deposits (plaque). This can reduce blood flow to the heart, leading to chest pain (angina), shortness of breath, or heart attacks. Risk factors for CAD include high blood pressure, high cholesterol, smoking, diabetes, and a sedentary lifestyle.

Heart Failure

Heart failure, also known as congestive heart failure, occurs when the heart is unable to pump blood effectively to meet the body’s needs. This condition can result from various heart problems, including coronary artery disease, high blood pressure, and cardiomyopathy (heart muscle disease). Symptoms of heart failure include fatigue, shortness of breath, swelling in the legs and ankles (oedema), and difficulty performing everyday activities. Management typically involves medications, lifestyle changes, and, in some cases, surgical interventions.

Arrhythmias

Arrhythmias are irregular heartbeats that can be either too fast (tachycardia), too slow (bradycardia), or erratic. Common types of arrhythmias include atrial fibrillation (AFib), ventricular tachycardia, and ventricular fibrillation. Arrhythmias can cause symptoms like palpitations, dizziness, fainting, and shortness of breath. Treatment options vary depending on the type and severity of the arrhythmia and may include medications, lifestyle modifications, and procedures such as ablation or the implantation of a pacemaker or defibrillator.

Valvular Heart Disease

Valvular heart disease involves damage or dysfunction of one or more of the heart’s valves, which can affect blood flow through the heart. The heart has four valves—the aortic, mitral, pulmonary, and tricuspid valves—that ensure blood flows in the correct direction. Conditions such as valve stenosis (narrowing) or valve regurgitation (leakage) can cause the heart to work harder and lead to symptoms like chest pain, fatigue, shortness of breath, and swelling in the legs. Treatment for valvular heart disease may involve medications, lifestyle changes, or surgical procedures like valve repair or replacement.

What are the Common Symptoms of Heart Disease?

Recognising the symptoms of heart disease early can lead to prompt medical intervention and better outcomes. Here are the common symptoms in more detail:

Chest Pain (Angina)

Chest pain is one of the most well-known symptoms of heart disease. It often feels like a tightness, pressure, squeezing, or burning sensation in the chest. This pain can radiate to the shoulders, arms, neck, jaw, or back. Angina typically occurs when the heart muscle doesn’t get enough oxygen-rich blood, especially during physical activity or stress. It’s crucial to remember that not all chest pain is a sign of heart disease, but any persistent or severe chest pain requires medical attention.

Shortness of Breath

Shortness of breath, also known as dyspnoea, can occur with or without chest pain. It may happen during physical exertion, while at rest, or even when lying flat. This symptom is often a result of the heart’s inability to pump blood effectively, leading to fluid buildup in the lungs (pulmonary congestion). Wheezing or a persistent cough may accompany shortness of breath in heart failure, which can worsen over time.

Fatigue

Unusual fatigue is a common symptom of heart disease, particularly in women. It’s common to describe this type of fatigue as overwhelming and unresponsive to rest. It can be a sign that the heart is struggling to meet the body’s demands for blood and oxygen. Fatigue may occur during physical activity or even at rest and can significantly impact daily activities and quality of life.

Irregular Heartbeats (Arrhythmias)

Arrhythmias are abnormalities in the heart’s rhythm, which can manifest as palpitations (the feeling of a racing, pounding, or fluttering heart). Some arrhythmias are harmless, while others can be life-threatening. Symptoms of arrhythmias can include dizziness, fainting, shortness of breath, and chest discomfort. Common types of arrhythmias include atrial fibrillation, ventricular tachycardia, and bradycardia.

Swelling (Edoema)

Swelling in the legs, ankles, feet, or abdomen can be a symptom of heart failure. This swelling, known as oedema, occurs when the heart’s reduced pumping efficiency leads to fluid buildup in the body’s tissues. Edoema can cause discomfort and may worsen over time. Weight gain and a feeling of tightness or heaviness in the affected areas are frequently associated with it.

Nausea and Dizziness

Nausea and dizziness can be symptoms of heart disease, especially in women. These symptoms may occur in conjunction with chest pain or shortness of breath. Dizziness can result from reduced blood flow to the brain, while nausea may be linked to the body’s response to decreased oxygen levels or the presence of other symptoms like chest pain.

Cold Sweats

Cold sweating can be a sign of a heart attack, especially when it happens in conjunction with other symptoms like chest pain or shortness of breath. This symptom is often described as sudden and profuse sweating that feels clammy and is not related to heat or physical exertion. Cold sweats can be a response to severe pain or stress on the heart.

Pain in Other Parts of the Body

Heart disease can cause referred pain in areas other than the chest. This pain can radiate to the arms (especially the left arm), shoulders, neck, jaw, or back. This type of pain is often associated with angina or a heart attack and can vary in intensity and duration.

Lightheadedness or Fainting

Lightheadedness or fainting (syncope) can occur when the heart’s pumping action is compromised, leading to a temporary drop in blood flow to the brain. This can result from severe arrhythmias, heart failure, or other cardiac conditions. Fainting episodes can be sudden and may require immediate medical attention.

Indigestion or Heartburn

Indigestion or heartburn-like sensations can sometimes be mistaken for heart disease symptoms. These gastrointestinal symptoms can occur with or without chest pain and may be more prevalent in women. It’s important to differentiate between typical indigestion and potential cardiac issues, especially if these symptoms are new, persistent, or associated with other heart disease signs.

How can one effectively manage heart disease in their daily life?

Managing heart disease involves a multifaceted approach that includes lifestyle changes, medication, and regular medical check-ups. Here are the key strategies for effective management:

Lifestyle Changes

1. Quit Smoking: Smoking is a major risk factor for heart disease. Quitting smoking can improve heart health almost immediately and reduce the risk of heart attacks and strokes.
2. Healthy Diet: Follow a heart-healthy diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit the intake of saturated fats, trans fats, sodium, and added sugars. This helps lower cholesterol levels, blood pressure, and overall heart disease risk.
3. Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. Include muscle-strengthening activities on two or more days per week. Exercise helps maintain a healthy weight, lowers blood pressure, and improves cardiovascular health.
4. Maintain a Healthy Weight: Achieving and maintaining a healthy weight reduces the strain on your heart and lowers the risk of heart disease. A balanced diet and regular physical activity are essential for weight management.
5. Limit Alcohol: If you drink alcohol, do so in moderation. For women, this means up to one drink per day, and for men, up to two drinks per day. Excessive alcohol consumption can increase blood pressure and contribute to heart disease.
6. Manage Stress: Chronic stress can negatively impact heart health. Practice stress management techniques such as mindfulness, meditation, deep breathing exercises, and hobbies to reduce stress levels.

Medications

1. Blood Pressure Medications: Medications such as ACE inhibitors, beta-blockers, calcium channel blockers, and diuretics help control high blood pressure, reducing the risk of heart disease complications.
2. Cholesterol-Lowering Medications: Statins, niacin, and fibrates are commonly prescribed to lower LDL (bad) cholesterol and raise HDL (good) cholesterol levels.
3. Blood Thinners: Anticoagulants and antiplatelet agents help prevent blood clots, reducing the risk of heart attacks and strokes.
4. Anti-Anginal Medications: These medications, such as nitrates, beta-blockers, and calcium channel blockers, help relieve chest pain (angina) by improving blood flow to the heart.
5. Diuretics: Diuretics help reduce excess fluid in the body, which can decrease the workload on the heart, especially in cases of heart failure.

Regular Medical Check-Ups

1. Routine Monitoring: Regular visits to your healthcare provider are essential for monitoring your heart health. This includes checking blood pressure, cholesterol levels, blood sugar levels, and other relevant health markers.
2. Diagnostic Tests: Your doctor may recommend tests such as electrocardiograms (ECG), echocardiograms, stress tests, and blood tests to assess heart function and detect any issues early.
3. Follow-Up Appointments: Regular follow-up appointments ensure that your treatment plan is effective and allow for adjustments if necessary. It’s important to discuss any new symptoms or side effects of medications with your healthcare provider.
4. Cardiac Rehabilitation: Cardiac rehabilitation is a structured programme that includes supervised exercise, education on heart-healthy living, and counselling to reduce stress and improve mental health. This programme is beneficial for those recovering from a heart attack, heart surgery, or managing chronic heart disease.

Cardiac Rehabilitation

Cardiac rehabilitation is a critical component of heart disease management for many patients. It typically includes:

1. Supervised Exercise: Safe, monitored exercise sessions to gradually improve cardiovascular fitness.
2. Education: Information on heart-healthy living, including diet, exercise, and stress management.
3. Counselling: Support to help patients cope with the emotional aspects of heart disease and make lasting lifestyle changes.
