Incidence of @entity299 and functional significance of changes in the electrocardiogram 10 years after radiotherapy for XXXX .

@entity1 @entity308 @entity66 @entity0 @entity5 @entity299
Late @entity299 after radiotherapy for @entity0 was studied in 197 @entity1 examined before, 6 months after, and 10 years after treatment. The 10-year follow-up was done by survey of the files of @entity1 who had died and re-examination of @entity1 who were alive and free of @entity5 . Among 95 @entity1 who died, 3 died of @entity66 . Autopsy in 32 @entity1 showed serious @entity299 in 3. Of 102 @entity1 alive at follow-up, 3 reported heart symptoms. Sixty-nine @entity1 participated in the re-examination. Electrocardiogram (ECG) abnormalities were found in 19% of these @entity1 before treatment; in 45% at 6 months, essentially due to T-wave changes in @entity1 who had received left-sided irradiation; and in 45% at 10 years, with fewer T-wave abnormalities but more @entity308 and ectopic beats. Average working capacity was 83 W before, 81 W at 6 months, and 84 W at ten years. Average heart volume was 680 ml before, 689 ml at 6 months, and 718 ml (P less than 0.01) 10 years after treatment. In conclusion, there was a high incidence of ECG T-wave changes, but they were reversible, and the perimyocardial damage indicated was functionally insignificant. The incidence of serious @entity299 was low.
