Sign 2: Shortness of Breath
Shortness of breath, or dyspnea, is another hallmark sign of cardiomyopathy. While it’s normal to huff and puff after intense physical activity, people with cardiomyopathy often experience breathlessness after only light exertion or even at rest.
Dyspnea in cardiomyopathy isn’t just a feeling of being “winded”. It’s an uncomfortable sensation where you feel you’re not getting enough air. It might be accompanied by a feeling of tightness in the chest or a need to gasp for air. This shortness of breath happens because, as the heart muscle weakens, it can’t pump enough oxygen-rich blood to meet the body’s needs. When this happens, the body diverts blood away from less vital organs, providing the heart and brain with a larger share.
Consequently, the effort needed for even basic tasks becomes too great, causing breathlessness. This sign is particularly noticeable during physical activities that were previously manageable, like climbing stairs or walking short distances. As cardiomyopathy progresses, it can also occur at rest or during sleep, which can lead to startling awakenings and a fear of sleep.
Breathlessness can significantly impact daily life and well-being. Therefore, if you notice this symptom, especially in conjunction with others on this list, don’t hesitate to seek medical advice. Remember, early detection could be crucial for effective management of cardiomyopathy. (2)
