Claim of Alperin v. Great Atlantic & Pacific Tea Co.
The claimant, on March 12, 1971, experienced acute heart failure or insufficiency due to excessive work effort, aggravating a pre-existing heart defect caused by a damaged aortic valve. The Workers' Compensation Board determined that a subsequent operation to replace the defective aortic valve and its sequelae were causally related to this work activity. Appellants contested this finding, arguing a lack of substantial evidence. However, the record contained unequivocal medical testimony confirming that the specific work effort caused the condition to become symptomatic, necessitating the operation to alleviate symptoms. The court affirmed the Board's decision, finding a clear causal link.
