Key legal question
Whether the insured showed a relevant change in circumstances under Art. 17 LPGA justifying revision of the pension decision
Extracted holding
The cardiac worsening identified by the new experts did not amount to a significant change in circumstances; the residual work capacity remained 85% and the practical impact on employability was insignificant.
Extracted reasoning
A new diagnosis alone is insufficient. Only the effect on work capacity matters. The additional limitation to avoid intense physical effort was too narrow and did not materially alter the range of suitable jobs compared with the earlier medical assessment.
