Kernrechtsfrage
Whether the medical situation and residual work capacity were sufficiently clarified without further expert evidence.
Extrahierter Entscheid
The record was sufficiently clarified; further investigations were unnecessary under anticipatory appraisal.
Extrahierte Begründung
The medical file, including angiological and general-practice reports plus a radiological exam, allowed assessment of work capacity. No concrete indications justified psychiatric or musculoskeletal further studies.
