Introduction
Poor blood supply to multiple organs and body parts leads to dependent edema, causing noticeable swelling in the legs and joints. Sudden worsening of heart failure due to dilated cardiomyopathy can result in acute pulmonary congestion, leading to severe shortness of breath and orthopnea. This may also cause increased or irregular heart rate, and without timely treatment, shock may occur.
Dilated cardiomyopathy, clinically referred to as "dilated heart disease," and heart failure, clinically known as cardiac insufficiency, may present varied late-stage manifestations when dilated cardiomyopathy leads to heart failure. Symptoms may include dependent edema, pulmonary congestion, or increased heart rate.
1. Dependent edema: Dilated cardiomyopathy can impair normal cardiac function, compromising blood supply to multiple organs. This often results in dependent edema, with noticeable swelling in the legs and joints. In severe cases, it may lead to pleural effusion or ascites.
2. Pulmonary congestion: A sudden worsening of heart failure in dilated cardiomyopathy can cause acute pulmonary congestion, leading to severe shortness of breath and orthopnea. Patients may also cough up pink, frothy sputum.
3. Increased heart rate: If left untreated, this condition severely affects normal heart function, causing tachycardia or arrhythmia. Without prompt treatment, shock may develop, potentially resulting in death, indicating a serious impact on health.
Upon experiencing these symptoms, patients should seek timely medical care. Daily rest should be appropriately maintained, and strenuous physical activity avoided to prevent increased cardiac workload.
