What are the classic symptoms of myopathy affecting cardiac function?

The classic symptoms of myopathy affecting cardiac function include chest pain and shortness of breath. Myopathy can lead to the weakening of the heart muscle, resulting in impaired cardiac function. When the heart is unable to pump effectively, it may lead to inadequate blood supply to various tissues, which manifests as chest pain. Additionally, as the heart struggles to maintain adequate circulation, patients often experience shortness of breath, particularly during exertion or when lying flat, due to fluid accumulation in the lungs (pulmonary congestion). These symptoms are critical in assessing cardiac-related issues stemming from myopathy, highlighting the importance of early identification and management of such conditions in clinical practice.
