Certiorari to review a decision of the Workers’ Compensation Court of Appeals which, with two judges dissenting, applied the presumption set forth in Minn.Stat. § 176.011, subd. 15 (1982), to find that the coronary arteriosclerosis which caused employee’s myocardial infarction was an occupational disease. We are satisfied that the statutory presumption was applicable in this case, but we reverse the award of benefits because we find that the employer overcame the presumption with uncontra-dicted medical evidence that the disease and disability were the result of recognized causative factors unrelated to the employee’s occupation.
The employee, Elmer Worden, sustained a heart attack while at home in bed in the early morning hours of September 17, 1979. At that time, he had been employed as a deputy sheriff for 14 years, first by Fillmore County for 5 years, then by Houston County, his present employer. Since January of 1979, he had worked as chief deputy sheriff, a position which entailed *695 more responsibility, more on-the-job pressure, and longer work hours than he had experienced previously.
Worden subsequently returned to work but sought workers’ compensation benefits, relying on the presumption of Minn.Stat. § 176.011, subd. 15 (1982), to claim that his heart attack and arteriosclerosis resulted from the nature of his employment. Houston County opposed application of the presumption, arguing that Worden had not undergone the preemployment physical examination that is required by the statute. Houston County further contended that even if the presumption did apply, it had been refuted by medical evidence that Wor-den’s coronary condition in fact resulted from causative factors unrelated to his employment. The compensation judge found that the presumption did apply and that the employer had failed to make the strong showing necessary to rebut the presumption. The Workers’ Compensation Court of Appeals affirmed that decision. Houston County petitioned this court for certiorari.
1. Minn.Stat. § 176.011, subd. 15 (1982), provides:
If immediately preceding the date of his disablement or death, an employee was employed on active duty * * ⅜ as a * * * sheriff or full time deputy sheriff of any county, and his disease is that of myocarditis, coronary sclerosis, pneumonia or its sequel, and at the time of his employment such employee was given a thorough physical examination by a licensed doctor of medicine, and a written report thereof has been made and filed with such * * * sheriff’s department of any county, which examination and report negatived any evidence of myocardi-tis, coronary sclerosis, pneumonia or its sequel, the disease is presumptively an occupational disease and shall be presumed to have been due to the nature of his employment.
In this case Houston County did not require and Worden did not undergo a physical examination at the time of his employment. Therefore, Houston County argues, this condition precedent to application of the statutory presumption was not established. We do not agree. The purpose of the statute’s physical examination and record requirement, as we noted in
Linnell v. City of St. Louis Park,
2. Having found the presumption applicable, we must determine whether the employer successfully overcame it. To rebut the presumption, the employer must make a strong showing either that the employee’s duties were significantly less stressful than those of most employees in his occupation or that his disease and disability resulted from recognized causative factors unrelated to his occupation.
Lin-nell,
When faced with a record containing such specific and uncontroverted medical evidence, we are compelled to reverse- the findings to the contrary. Had there been expert testimony on this issue, the opinions expressed in the reports could have been explicated, tested, and perhaps qualified. And, had there been such testimony, we would afford deference to the factfinder’s unique opportunity to scrutinize the witnesses and judge their credibility.
