Heart health is essential, yet many people remain unaware of the subtle signs that could indicate a weakening heart. Cardiovascular surgeon Dr. Jeremy London, known for his straightforward advice on social media, has highlighted several red flags that everyone should be aware of. Although these tips aren’t a substitute for medical advice, they can offer insight into when it might be time to consult a doctor. Here’s how to recognize signs of a weak heart and understand the steps you can take to protect your health.

Why Understanding Heart Health Matters

The heart works tirelessly to pump blood and supply oxygen throughout the body. Any disruption in its efficiency can lead to serious health consequences. Conditions like heart failure, coronary artery disease, and arrhythmias can develop gradually, often showing symptoms that are easy to overlook. Knowing these early warning signs can help in seeking timely treatment, preventing further damage, and supporting long-term cardiovascular health.

Key Signs of a Weak Heart

Let’s explore some of the most common indicators that could suggest a heart is struggling. These symptoms may appear subtle, but they’re worth taking seriously.

Shortness of Breath

One of the earliest signs of heart trouble is persistent shortness of breath. Dr. London explains that feeling winded or out of breath during routine activities—such as walking up stairs or taking a brisk walk—could signal that your heart isn’t pumping effectively. This can result from conditions like coronary heart disease, heart failure, or arrhythmias.

The British Heart Foundation also advises taking breathlessness seriously and consulting a healthcare provider as soon as possible. While shortness of breath isn’t always tied to heart problems, it’s a potential warning sign that warrants investigation, especially if it occurs regularly without intense exertion.

Another red flag for heart health is orthopnea, or shortness of breath that appears when lying flat. This condition can cause difficulty breathing at night, often leading to interrupted sleep or the need to prop oneself up with pillows. According to Dr. London, orthopnea may indicate excess fluid in the lungs, a common consequence of heart-related issues.

Orthopnea typically improves upon sitting or standing, which relieves pressure on the lungs. However, its presence can be a sign of heart failure, as the heart may struggle to pump blood efficiently, causing fluid buildup. Anyone experiencing this symptom regularly should discuss it with their doctor, as it can interfere with both sleep quality and overall health.

Swollen Legs and Ankles

Swelling in the legs and ankles, also known as edema, is another indicator of potential heart issues. When the heart is too weak to pump blood effectively, blood can back up in the veins, especially in the lower extremities. This results in fluid leakage into surrounding tissues, leading to noticeable swelling in the legs, ankles, and sometimes even the abdomen.

The National Health Service (NHS) also notes that persistent leg swelling can signal heart failure or other cardiovascular conditions. Monitoring this symptom and seeking professional evaluation can help catch heart problems early and avoid complications.

Heart Health Testing and Diagnosis

So, how can you determine whether these symptoms indicate a weak heart? Dr. London suggests that a simple echocardiogram, or an ultrasound of the heart, can provide valuable insights. This non-invasive test uses sound waves to create images of the heart, allowing doctors to examine its structure and function.

One crucial measure assessed in an echocardiogram is the ejection fraction, which indicates the percentage of blood pumped out of the heart with each beat. A normal ejection fraction is typically between 65% and 70%. Lower percentages can indicate weakened heart function, often linked to heart failure or other cardiovascular diseases. If the ejection fraction falls below these levels, further investigation may be necessary to address potential risks and treatment options.

How Poor Heart Function Impacts Surgery Outcomes

According to Dr. London, heart function significantly influences how well patients fare in surgical procedures. A strong heart generally withstands the stresses of surgery better, aiding in recovery and reducing complications. Patients with weakened hearts often face more challenging recoveries, as the heart’s reduced capacity to pump blood effectively can strain the body during and after surgery. For those with known heart issues, strengthening the heart before any planned surgeries can make a meaningful difference in outcomes.

Ways to Support Heart Health Naturally

Fortunately, several lifestyle adjustments can support heart health and, over time, improve symptoms like shortness of breath and edema. Here are some effective strategies:

• Exercise Regularly: Physical activity strengthens the heart and improves circulation. Aim for at least 150 minutes of moderate exercise per week, such as walking, swimming, or cycling.
• Eat a Heart-Healthy Diet: A diet rich in fruits, vegetables, whole grains, and lean proteins supports cardiovascular health. Omega-3 fatty acids, found in fish like salmon, are particularly beneficial for reducing inflammation and maintaining a healthy heart rhythm.
• Limit Sodium Intake: Excess salt can lead to fluid retention, worsening symptoms like swollen legs and shortness of breath. Opt for fresh foods and avoid processed items, which are often high in sodium.
• Stay Hydrated: Drinking enough water helps maintain blood volume, which supports proper circulation. However, those with heart failure may need to balance fluid intake carefully—consult a healthcare provider for guidance.
• Manage Stress: Chronic stress can strain the heart and raise blood pressure. Techniques like meditation, deep breathing, and mindfulness can help manage stress and promote relaxation.

Recognizing When to Seek Professional Help

While these lifestyle changes can improve heart health, there are times when medical intervention becomes necessary. If you experience any of the red flags Dr. London discussed—especially if they worsen over time—it’s essential to seek a medical evaluation. A healthcare provider can assess these symptoms, conduct necessary tests, and create a personalized plan to support your heart health.

Ignoring symptoms of a weak heart can lead to progressive heart failure, which can impact quality of life and shorten lifespan. Early intervention, however, can lead to effective management of symptoms and, in many cases, a significant improvement in heart function.

Conclusion: Listen to Your Heart and Act Early

Keeping an eye out for symptoms like shortness of breath, difficulty breathing while lying flat, and swollen legs can provide critical early warnings about heart health. By understanding and recognizing these red flags, you can take proactive steps to protect your heart. While lifestyle changes can significantly support heart health, don’t hesitate to seek medical advice if symptoms persist or worsen. Early intervention is often the key to managing heart issues effectively, helping you maintain a strong, healthy heart for years to come.
