MARK WILLIAMS vs. CITY OF PASADENA
This case involves a police officer claiming industrial injury to his heart due to hypertensive heart disease, a condition he argued was distinct from previously compensated hypertension. The Workers' Compensation Appeals Board (WCAB) rescinded the administrative law judge's decision, finding the claim was not barred by res judicata. The WCAB clarified that while hypertension alone is not considered heart trouble, left ventricular hypertrophy, as diagnosed in the current claim, constitutes a distinct condition. The case is returned to the trial level for further proceedings on other unresolved issues.
