OPINION
This is an appeal from a decision of the Industrial Accident Board (Board) denying claimant’s (Mooney’s) petition for workmen’s compensation for a heart attack.
The facts are not disputed: Mooney has been in the construction trade for over 30 years, the last 10 of which have been spent as a construction superintendent for a variety of construction companies. On November 1, 1979, he began working for Benson Management Company (Benson) in such a position; a job admittedly stressful because of the nature of his responsibilities and the people he had to deal with on a daily basis. On November 27,1979, Mooney experienced tightness and pain in his chest while arguing with a painting sub-contractor in the normal course of his job. The pain subsided and he went to his family doctor, who referred him to a specialist in cardiology, Dr. Levy. Dr. Levy performed a variety of tests, prescribed medication, and continued to see him until January 8, 1980. Mooney continued to work for Benson until May 9, 1980, when he suffered a severe myocardial infarction which required his hospitalization. He seeks compensation for the economic loss and medical bills caused by the May 9 heart attack.
The Board made factual findings that Mooney had a pre-existing heart condition prior to May 9, 1980, and that he was not involved in any unusual exertion on that date. Compensation was denied on that basis.
Mooney makes two arguments on appeal: (1) That the Board erred as a matter of law when it applied the “Unusual Exertion” theory to the facts of his case rather than the “Cumulative Detrimental Effect” theory; and (2) that the Board’s finding of a pre-existing heart condition is not supported by substantial evidence.
Mooney intertwines these two arguments by asserting that the pre-existing heart condition the Board presumes to find is really the cumulative detrimental effect of his job on his health and as a consequence he need only prove “usual exertion” on the day of his injury.
Under the well-established standard and scope of review imposed on this Court by statute and case law, we can only examine the record and determine if there is substantial evidence to support the findings and conclusions of the Board. If such evidence exists and the Board has made no error of law, its decision must be affirmed. 29 Del.C. § 10142; Air Mod Corp. v. Newton, Del.Supr., 215 A.2d 434 (1965).
I believe the Board applied the correct theory to the facts of this case. Mooney’s only argument before the Board was that he did not have to prove unusual exertion because there was no pre-existing heart condition. He did not argue the “cumulative detrimental effect” theory before the Board, and should not be permitted to raise it for the first time on appeal. See Wilmington Trust Company v. Conner, Del. Supr., 415 A.2d 773 , 781 (1980).
Having decided that the Board applied the correct theory in this case, the only remaining issue is whether there is substantial evidence in the record to support the Board’s finding that Mooney was suffering from a pre-existing heart condition when he had his heart attack on May 9.
The law on heart attacks in workmen’s compensation eases in Delaware is clear. “Unusual exertion is a prerequisite to compensation in a heart or back case where a pre-existing condition is shown”. Willis v. New Castle County, Del.Supr., 371 A.2d 1072 , 1073 (1976). That rule was reaffirmed recently in Boulevard Electric Sales v. Webb, Del.Supr., 428 A.2d 11 (1981).
My review of the record reveals that substantial competent evidence exists to support the Board’s finding of a pre-exist-ing heart condition. Admittedly, much of the medical testimony and evidence was confusing and sometimes contradictory. However, it is the role of the Board, not this Court, to resolve conflicts in testimony and issues of credibility and to decide what weight is to be given to the evidence presented. See Boulevard Electric, supra; Delaware Tire Center v. Fox, Del.Super., 401 A.2d 97 (1979).
Supporting the Board’s conclusion are the following evidentiary items: Dr. Levy testified that when he examined Mooney after the November 27, 1979, incident, the “... electrocardiogram ... was within normal limits, but the symptomatology was so typical for coronary artery disease that I gave him nitroglycerin and another drug called Isordil, which are used in cases of known coronary artery disease”. (R 9). He defined coronary artery disease as the buildup of fatty deposits in the coronary arteries which produces a blood clot in the artery, and that this is something that in some people, takes quite a long time to occur (R 21-22). He did not know if such a buildup had happened to Mooney because there was no history of it and no tests had been done to determine it (R 22-23). He acknowledged that such a buildup over time can occur without any outward symptoms (R 22-23). It was the duty of the Board to decide which aspect of his testimony to believe, Delaware Tire Center v. Fox, supra, and the Board apparently believed that the coronary artery disease existed at least as of November 27, 1979.
Thus, I believe there is substantial evidence to support the Board’s finding that claimant had a pre-existing heart condition prior to May 9, 1980. Under the law as stated in Willis and Boulevard, supra, the existence of a pre-existing heart condition requires the claimant to prove his heart attack was caused by some sort of unusual exertion. Mooney has admitted throughout his briefs in this appeal and at the hearing before the Board that the stress of his job on May 9 was the same as on any other routine working day. Thus, there is substantial evidence to support the Board’s finding that Mooney was not involved in any unusual exertion on May 9 when he had his attack.
The Board’s decision is affirmed.
