We agree with the administrative law judge that the issue of medical causation is dispositive. Section 287.020.2 RSMo provides, as follows:
An injury is compensable if it is clearly work related. An injury is clearly work related if work was a substantial factor in the cause of the resulting medical condition or disability. An injury is not compensable because work was a triggering or precipitating factor.
The parties presented conflicting medical expert testimony on the issue of medical causation. Employee provides the testimony of Dr. Cohen, who believes employee's work was a substantial factor in the cause of his stroke. Dr. Cohen acknowledged that employee exhibited several of the most common risk factors for stroke, such as high blood pressure, high cholesterol, and diabetes. But Dr. Cohen explained that employee's work involved the type of stress that would cause someone with high blood pressure to have even higher blood pressure. Ultimately, Dr. Cohen opined that employee's work caused his high blood pressure to worsen which in turn was a substantial factor that caused him to suffer the stroke.
Employer, on the other hand, provides the testimony of Dr. Goldring, who believes employee's stroke was the result of his underlying vascular risk factors. Dr. Goldring disagreed with Dr. Cohen's analysis and pointed out that Dr. Cohen's causation opinion

relied on the speculative premise that employee's work actually caused him to experience an increase in his already high blood pressure. Dr. Goldring characterized this premise as "a stretch." Dr. Goldring opined that stress is not one of the recognized causes of stroke, and that he'd never even heard of a stroke being work-related where there wasn't any trauma involved.
After carefully considering the testimony from both of these experts, we agree with the administrative law judge that Dr. Goldring is more credible.
We conclude that work was not a substantial factor causing employee to suffer the stroke on March 31, 2004, or any resulting disability.
**All other issues moot**
We note that the administrative law judge went on to address a number of other issues and to render findings, such as the extent of employee's permanent partial disability, that are moot by reason of employee's failure to meet his burden of proof on the issue of medical causation. We do not adopt any of the administrative law judge's findings or comments related to the moot issues of past medical expenses, future medical care, or the nature and extent of permanent partial disability.
**Conclusion**
Based on the foregoing, the Commission concludes and determines that employee failed to demonstrate that his work was a substantial factor causing him to suffer a stroke at work.
The claim for compensation is denied.
The award and decision of Administrative Law Judge Edwin J. Kohner, issued September 2, 2011, is attached and incorporated only to the extent it is not inconsistent with our findings, conclusions, and analysis herein.
Given at Jefferson City, State of Missouri, this 5th day of April 2012.
