THORNTON, J.

This is an appeal from a Workers’ Compensation Board order reversing the referee and awarding claimant 50 percent unscheduled disability for his low back. The issue is the extent to which claimant’s heart attack, suffered subsequent to the time his back disability forced retirement from his job as a pipe fitter, contributed to his inability to work.
