Patients with rheumatic heart disease must avoid emotional excitement, as it can lead to an increased heart rate and an increased burden on the heart. They must also avoid overexertion, as it can exacerbate heart failure, and a high-salt diet, as consuming too much salt can lead to an increased fluid volume, worsening heart burden and potentially inducing or worsening heart failure. Patients with rheumatic heart disease should generally maintain a pleasant mood, rest adequately, avoid overexertion, eat light and easily digestible foods, and have a high-protein diet. They should also avoid cold and prevent colds to avoid worsening the burden on the heart and the symptoms of heart failure.
