Generally, for patients with mild rheumatic heart disease, pregnancy is not recommended. Pregnancy can sometimes increase the burden on the heart, leading to heart failure. If this condition is treated in time, or if the patient has relatively good heart function and rheumatic heart disease rarely recurs, pregnancy can still be considered for young female patients. However, for rheumatic heart disease patients experiencing palpitations and chest tightness, it is best not to consider pregnancy. This condition can increase the load on the heart, especially in the late stages of pregnancy, and may further exacerbate heart failure.
