ELEUTERIO POLINA, vs. RALPHS GROCERY STORE
The Workers' Compensation Appeals Board denied Ralphs Grocery Store's petition for reconsideration. Defendant argued the administrative law judge erred in finding hypertension and stroke industrially caused. The Board affirmed the judge's decision, relying on the qualified medical evaluator's opinion that work stress and night shift work were contributing factors to the applicant's hypertension, which in turn led to the stroke. The Board emphasized that industrial factors only need to be a contributing cause for an injury to be compensable, and the location of symptom onset is irrelevant if the exposure occurred during employment.
