Cardiomyopathy is a group of diseases that affect the heart muscle, leading to structural and functional abnormalities. These conditions can be classified into various types, including dilated, hypertrophic, restrictive, and arrhythmogenic right ventricular cardiomyopathy, each presenting with a range of symptoms that often overlap with those of heart failure.
One of the most prevalent symptoms across all types of cardiomyopathy is shortness of breath, which can occur during physical activity or even at rest. This is often accompanied by extreme fatigue, making it difficult for patients to perform everyday activities .
Patients frequently experience swelling in the legs, ankles, and feet due to fluid retention. This peripheral edema is a common sign of heart failure associated with cardiomyopathy .
Orthopnea, or difficulty breathing while lying flat, and paroxysmal nocturnal dyspnea, which involves sudden shortness of breath during sleep, are also common symptoms. These symptoms are indicative of fluid accumulation in the lungs .
Irregular heartbeats or palpitations are frequently reported by patients with cardiomyopathy. These can range from mild fluttering to severe arrhythmias, which may lead to syncope (fainting) or presyncope (near fainting) .
Chest pain, often described as tightness or pressure, is another symptom that can occur, particularly in hypertrophic cardiomyopathy. This pain can be exacerbated by physical exertion or emotional stress .
Dizziness and lightheadedness are common, especially in hypertrophic cardiomyopathy, where they can be triggered by changes in posture or exertion. These symptoms are often related to abnormal blood pressure responses during physical activity .
A persistent cough, sometimes producing frothy sputum, and wheezing can occur due to fluid buildup in the lungs. These respiratory symptoms are more pronounced in advanced stages of cardiomyopathy .
In conditions like peripartum cardiomyopathy, emotional symptoms such as anxiety, fear, and feelings of impending doom are reported. These psychological symptoms can significantly impact the quality of life and may complicate the clinical picture.
Patients with hypertrophic cardiomyopathy often experience exertional dyspnea, presyncope, and atypical chest pain. Syncope, especially during or after physical activity, is a characteristic symptom .
Dilated cardiomyopathy typically presents with symptoms of heart failure, including reduced ejection fraction, peripheral edema, and fatigue. Arrhythmias and sudden cardiac death are also significant risks .
This less common type is associated with symptoms of systemic disease, such as amyloidosis, and presents with severe dyspnea and fatigue. The restrictive nature of the heart muscle limits its ability to expand and contract effectively.
This type is characterized by ventricular arrhythmias and can lead to sudden cardiac death. Symptoms often include palpitations, syncope, and heart failure .
Symptoms in peripartum cardiomyopathy include shortness of breath, excessive fatigue, swelling, and palpitations. Emotional symptoms such as anxiety and fear are also prevalent .
Cardiomyopathy encompasses a range of heart muscle diseases with overlapping symptoms primarily related to heart failure. Common symptoms include shortness of breath, fatigue, edema, palpitations, and chest pain. Specific types of cardiomyopathy may present with unique symptoms, such as syncope in hypertrophic cardiomyopathy and arrhythmias in arrhythmogenic right ventricular cardiomyopathy. Early recognition and management of these symptoms are crucial for improving patient outcomes.
