Introduction
If a patient with heart disease experiences leg swelling, it is typically caused by heart failure—especially right-sided heart failure—which leads to systemic congestion and readily results in lower-extremity edema. Leg swelling in patients with heart disease must be taken seriously. Prompt evaluation at a reputable hospital is essential, followed by active treatment with diuretics, positive inotropic agents, and vasodilators.

We often encounter various discomforts in daily life. Regardless of the nature of the issue, it warrants our serious attention. We should proactively address it using appropriate methods to prevent the condition from worsening. Leg swelling is a common symptom; however, its underlying causes vary among individuals. So, what causes leg swelling in patients with heart disease?

Causes of Leg Swelling in Heart Disease

If a patient with heart disease develops leg swelling, it is typically due to heart failure—particularly right-sided heart failure—which leads to systemic venous congestion and subsequently causes lower-limb edema. Leg swelling in cardiac patients must be taken seriously. Prompt evaluation at a reputable hospital is essential, followed by active treatment with diuretics, positive inotropic agents, and vasodilators. However, leg swelling in heart disease patients may also stem from kidney disease; therefore, renal function tests should be performed at a qualified medical facility to rule out this possibility. During this period, patients must prioritize rest, avoid staying up late or overexertion, and limit fluid intake.

Edema has numerous potential causes—not exclusively heart disease. Other contributors include hypertension, viral infections, valvular heart disease, advanced chronic kidney disease, end-stage liver disease, and malnutrition. Rheumatic valvular heart disease results from rheumatic activity affecting the heart valves, leading to conditions such as mitral stenosis or regurgitation—and other valve abnormalities—ultimately causing cardiac enlargement, impaired cardiac function, and arrhythmias.

Patients are advised to follow a low-salt, low-fat diet, avoiding high-fat and high-sodium foods. Instead, they should consume more green vegetables—such as celery and Chinese cabbage—as well as fresh fruits. We hope this information proves helpful to you.
