Claim of Maynard v. Industrial Welding Corp.
Claimant suffered a myocardial infarction in April 1972, returning to work in January 1973 with restrictions. Work demands gradually increased, leading to heavy lifting similar to pre-infarction levels by August 1973. On August 29, 1973, claimant experienced multiple onsets of chest pain at work, which the Workers’ Compensation Board found to be an accidental injury aggravating pre-existing heart damage and necessitating coronary artery bypass surgery in September 1974. The appellate court, however, found insufficient evidence to support the board's conclusion that an accidental injury occurred on August 29, 1973, or that the post-August 29 coronary insufficiency was work-related, stating that the work merely exposed a pre-existing disease without causing further damage. The decision of the Workers' Compensation Board was reversed and the matter remitted.
