These affections demand no dietetic treatment. They are a part of some general disease, such as rheumatism and the exanthemata, or of a local infection and toxemia, such as diphtheria or tonsillitis. The diet that is indicated for the principal malady must be adhered to when these cardiac complications arise. During convalescence care must be taken to avoid increasing the blood pressure unduly by drinking too much or by overloading the stomach and bowels. In these ways the heart, already weakened by the acute affection from which it has suffered, may easily be dilated or tired. The diet should be nutritious and concentrated. The bowels should be regularly and thoroughly moved.
