Questão jurídica principal
Whether the insured showed a legally relevant deterioration justifying revision from a half pension to a full disability pension.
Decisão extraída
No relevant worsening was proven; the remaining work capacity in adapted work stayed at 75%.
Fundamentação extraída
The medical reports did not establish a significant change since the original award. Post-angioplasty recovery was favorable, and later complaints were not objectively supported enough to show total incapacity.
