Surgeon reveals how to tell if your heart is weak or strong and explains the ‘red flags’ to look out for
Cardiovascular surgeon Dr. Jeremy London discusses key indicators of a weak heart and the “red flags” to watch for. One of the earliest signs of heart issues is shortness of breath, especially with mild exertion, which suggests the heart isn’t pumping efficiently. Difficulty breathing while lying flat, or orthopnea, can indicate heart failure due to fluid buildup in the lungs. Swelling in the legs and ankles is another red flag of poor circulation and heart weakness. Dr. London emphasizes monitoring the ejection fraction, a measure of how much blood the heart pumps out with each beat—anything significantly lower than 65-70% signals heart weakness.
Other symptoms include fatigue, decreased exercise tolerance, and chest discomfort, which can be signs of heart strain. Regular checkups are crucial for early detection, particularly for those with risk factors like family history, high blood pressure, or diabetes. Lifestyle adjustments, such as regular exercise, a heart-healthy diet, managing stress, and avoiding smoking and excess alcohol, can support heart health. Staying vigilant and proactive is essential for maintaining a strong heart and preventing serious cardiovascular conditions.
