Early signs of heart disease in seniors: How to recognise them

Why early detection of heart disease is crucial for seniors

As people age, their hearts and blood vessels undergo changes that can lead to cardiovascular problems. Atherosclerosis (hardening of the arteries), high blood pressure, and weakened heart muscles all contribute to an increased risk of heart disease in older adults. Many heart diseases develop slowly over time, with subtle symptoms that are easy to overlook. Recognising these symptoms early allows for timely intervention, potentially preventing a heart attack, stroke, or heart failure.

1. Chest pain (Angina)

One of the most well-known symptoms of heart disease is chest pain, also known as angina. This pain is often described as a feeling of tightness, pressure, or heaviness in the chest. It can sometimes spread to the arms, neck, back, or jaw.

What to look for: Chest pain that occurs during physical activity or emotional stress, and eases with rest, is a common sign of coronary artery disease (CAD). CAD occurs when the arteries supplying blood to the heart become narrowed or blocked, reducing blood flow.

When to seek help: If chest pain is persistent, worsening, or accompanied by other symptoms such as nausea, sweating, or shortness of breath, it could be a sign of a heart attack. Immediate medical help should be sought by calling emergency services.

2. Shortness of breath (Dyspnoea)

Shortness of breath is another critical indicator of heart problems, particularly in older adults. Many seniors assume that breathlessness is a normal part of ageing, but it can actually be a sign of heart failure or other cardiovascular issues.

What to Look For: Difficulty breathing during simple activities like walking up stairs or even at rest could indicate that the heart is not pumping effectively. This condition, known as heart failure, causes fluid to build up in the lungs, making it harder to breathe.

When to Seek Help: If shortness of breath becomes frequent, particularly if it worsens when lying flat, or is accompanied by chest pain or fatigue, it’s essential to contact a healthcare provider. Sudden, severe shortness of breath should prompt an immediate call to emergency services.

3. Fatigue and weakness

Unexplained fatigue is one of the more subtle signs of heart disease, particularly in seniors. While occasional tiredness is normal, persistent fatigue that affects daily activities can signal that the heart is struggling to supply the body with enough oxygen-rich blood.

What to look for: Seniors may notice they feel unusually tired after light activities, such as walking short distances or even after resting. Heart failure or arrhythmias (irregular heartbeats) can cause this kind of fatigue, as the heart works harder to pump blood.

When to seek help: If fatigue is ongoing, and other symptoms like swelling in the legs or difficulty breathing are present, it’s important to see a doctor. Fatigue that limits mobility or daily functioning should never be ignored.

4. Dizziness or light-headedness

Dizziness or light-headedness can occur if the heart is not pumping enough blood to the brain. While dizziness can result from many factors, recurrent episodes in seniors may be linked to heart conditions such as low blood pressure, arrhythmias, or heart valve issues.

What to look for: Dizziness that occurs when standing up or during physical activity could indicate heart-related issues. Fainting (syncope) is a more serious symptom that suggests a significant heart problem, such as valve disease or atrial fibrillation.

When to seek help: Recurrent dizziness, especially if accompanied by chest pain or shortness of breath, should be evaluated by a doctor. Any fainting episode should be treated as an emergency.

5. Swelling in the legs, feet, or ankles

Swelling, particularly in the legs, feet, or ankles, can be a sign of heart failure. When the heart is unable to pump blood efficiently, fluid can build up in the lower extremities, leading to noticeable swelling.

What to look for: Swelling that persists throughout the day or worsens after being on the feet for extended periods may be a sign of fluid retention caused by heart failure.

When to seek help: If swelling occurs suddenly, is painful, or is accompanied by shortness of breath or fatigue, it’s crucial to seek medical advice.

6. Irregular heartbeat (Arrhythmia)

An irregular heartbeat, or arrhythmia, is another potential warning sign of heart disease. While occasional heart palpitations are common and often harmless, frequent or persistent irregular heartbeats can indicate a serious heart condition.

What to look for: Seniors may feel their heart skipping beats, fluttering, or racing. These symptoms can be caused by various conditions, including atrial fibrillation (AFib), which increases the risk of stroke.

When to seek help: If an irregular heartbeat lasts for more than a few minutes, or is accompanied by other symptoms like chest pain, dizziness, or shortness of breath, it’s important to see a healthcare provider promptly.

Preventative measures for seniors

Recognising the early signs of heart disease is vital, but there are also preventative measures seniors can take to reduce their risk of developing heart problems.

- Regular check-ups: Seniors should visit their doctor regularly to monitor blood pressure, cholesterol, and blood sugar levels. Early detection of risk factors can prevent the progression of heart disease.
- Healthy diet: A diet rich in fruits, vegetables, whole grains, and lean proteins supports heart health. Reducing sodium and saturated fat intake can lower blood pressure and cholesterol levels.
- Physical activity: Engaging in regular physical activity, such as walking, swimming, or gentle exercise classes, strengthens the heart and improves circulation.
- Quit smoking: Smoking is a major risk factor for heart disease. Quitting smoking can significantly improve heart health, even in older adults.
- Manage stress: Chronic stress can raise blood pressure and contribute to heart disease. Relaxation techniques, such as yoga, meditation, or deep breathing exercises, can help seniors manage stress and improve overall heart health.

For seniors, recognising the early warning signs of heart disease can mean the difference between life and death. Symptoms like chest pain, shortness of breath, fatigue, dizziness, and swelling should never be ignored. By paying attention to these signals and seeking timely medical help, seniors can prevent serious complications and maintain a healthier, more active life.
