Patients with rheumatic heart disease should avoid overexertion and getting angry. Both overexertion and anger can increase the heart's burden, leading to a worsening of the heart disease. Patients should consume easily digestible foods and avoid spicy and greasy foods because these can cause indigestion or gastrointestinal symptoms, which in turn can increase the burden on the heart. A low-salt diet is also recommended; avoid eating overly salty dishes. Consuming foods high in salt can lead to retention of sodium and water in the blood, which increases the heart's burden, and in severe cases, can lead to heart failure.
