dissenting.
As I understand the law governing the factual situation before us, in order for the plaintiff to recover compensation for a change of condition, the plaintiff has the burden of showing that the subsequent heart attacks which resulted in total disability were the direct and natural result of the original heart attack. Professor Larson, in his treatise on workers’ compensation law, states:
The basic rule is that a subsequent injury, whether an aggravation of the original injury or a new and distinct injury, is compensable if it is the direct and natural result of the compensable primary injury.
1 A. Larson, The Law of Workmen’s Compensation § 13.11, at 3-348.91 (1976) (emphasis added). In discussing the range of compensable consequences flowing from a primary compensable injury, Professor Larson says this:
*255The issue in all of these cases is exclusively the medical issue of causal connection between the primary injury and the subsequent medical complications. . . . [D]enials of compensation in this category have invariably been the result of a conclusion that the requisite medical causal connection did not exist.
1 A. Larson, Workmen’s Compensation Law § 13.11(a), at 3-358 to 3-359 (1976) (footnotes omitted). See Starr v. Paper Company, 8 N.C. App. 604, 175 S.E. 2d 342, cert. denied, 277 N.C. 112 (1970). In the case at bar, the plaintiff has the burden of showing that the June 1981 myocardial infarction which changed the condition from partial to total disability was the direct and natural result of the first compensable attack. It is insufficient for the plaintiff to merely show that the damage from the first myocardial infarction, when coupled with the damage from the subsequent infarctions, contributed in some measure to his present disability. As noted by Deputy Commissioner McCrodden in her opinion and award, Chairman Stephenson in his dissenting opinion to the Commission’s award, and Judge John Martin in his dissenting opinion in the Court of Appeals, the evidence in this case totally fails to satisfy this requirement.
Following the primary compensable heart attack on 12 April 1979, the plaintiff was hospitalized until 2 May 1979. The plaintiff returned to full-time work on 15 July 1979 and performed his normal duties for a period of nine months without any symptoms of heart difficulty. In August of 1980, the plaintiff suffered another myocardial infarction while he was walking through a flea market during his leisure time. Following a period of recuperation, the plaintiff was able to return to work. The plaintiff suffered an additional myocardial infarction in June of 1981 while he was sleeping at home, and since that date, he has been unable to work.
Dr. Hindman, a cardiologist who treated the plaintiff, testified at the hearing on 13 April 1984 as a medical expert. He stated that the plaintiff had a history of high blood pressure for three years prior to the original myocardial infarction which occurred on 12 April 1979. Dr. Hindman defined a myocardial infarction as being a death of heart muscle resulting from an interruption of the blood flow to the heart muscle. Dr. Hindman further testified that, in his opinion, the plaintiff was suffering *256from advanced coronary artery disease and that this disease existed prior to the plaintiffs initial myocardial infarction on 12 April 1979. Dr. Hindman stated that coronary artery disease is a progressive illness and can progress very rapidly. Dr. Hindman said that the plaintiffs coronary artery disease was so advanced that in May of 1983 one of his coronary arteries was 100% blocked, while the other two were 75% to 95% blocked. The plaintiff suffered from angina, which resulted from occlusions or blockages of his coronary arteries. It is important to note that Dr. Hindman did not testify that the myocardial infarctions that occurred in August of 1980 and June of 1981 were the direct and natural result of the first myocardial infarction. To the contrary, Dr. Hindman made it clear that the second and third myocardial infarctions were the result of the continued progression of the plaintiffs coronary artery disease.
The damage to the plaintiffs heart muscle which resulted from the myocardial infarction on 12 April 1979 did not prevent the plaintiff from returning to his regular job. According to Dr. Hindman, this fact indicated that the plaintiffs heart muscle was continuing to receive an adequate blood flow following the first myocardial infarction. Dr. Hindman noted that the ability of the plaintiffs heart to pump blood to his body had been affected by the first myocardial infarction, but the plaintiffs heart was still strong enough to enable the plaintiff to perform his normal job without any coronary symptoms.
Of some twelve pages of summary of the medical evidence in the record before this Court, the majority has chosen to anchor its opinion on a one-sentence quotation from that summary. That one sentence is as follows:
It is my opinion that Mr. Weaver’s present disability is a combination of the cumulative damage of the heart muscle and the continued underlying coronary occlusions that still cause him angina.
On the basis of this one sentence, the majority concludes that “[finding of fact number 9 was clearly supported by competent evidence.” I do not agree with that conclusion. Finding of fact number 9 was as follows:
9. Plaintiffs total incapacity to earn wages was caused by a combination of the cumulative damage to the heart mus*257cle resulting from his initial compensable heart attack, his three subsequent attacks and the continued underlying coronary occlusions that also cause angina.
Neither the quoted testimony nor the finding of fact even address the question of whether the subsequent attacks which produced the changed condition were the direct and natural result of the first compensable heart attack. From any fair reading of the entire medical testimony, one would have to conclude that the second and third heart attacks resulted solely from the continued progression of the claimant’s coronary artery disease and were in no way triggered by, caused by, or the direct and natural result of his first attack.
It is my position that, during the course of the hearing, the claimant failed to elicit any testimony from Dr. Hindman which demonstrated that his change of condition was the direct and natural result of the original compensable heart attack. On the contrary, he testified that the two subsequent myocardial infarctions were caused by progressive coronary artery disease that predated the original compensable attack. Because the claimant failed to establish a causal relationship between the compensable injury and the subsequent myocardial infarctions, he has failed to show a compensable change of the condition under N.C.G.S. § 97-47.
I also agree with the Commissioner (then Chairman) Stephenson of the Industrial Commission, who dissented from the Commission’s order, and with Judge Martin, who dissented from the opinion of the Court of Appeals, that the Commission and the majority of the panel below has applied, without saying as much, the “significant contribution” test recently adopted by this Court in the occupational disease field. In effect, the majority has held that if this claimant’s permanent total disability is significantly contributed to by his first compensable heart attack, he is entitled to compensation for that percentage of his disability contributed by the first attack. In my view, this is a totally inappropriate test in cases where the permanent total disability results from a series of heart attacks, only the first of which is work related.
Under the majority opinion, as I understand it, if a worker suffers any heart attack during the course and scope of his employment, he will receive compensation for a change of condi*258tion resulting from a second, further disabling heart attack, regardless of where that heart attack occurs and regardless of the cause or extent of the second heart attack or its contribution to the plaintiffs disability. In a case like the one before us now, the result would be no different if the heart attack which eventually totally disabled the claimant occurred while he was scaling the Matterhorn or in bed with a paramour, so long as a physician testifies that the total disability results from a “combination” of the series of attacks and any other possible underlying conditions that might be preexisting. This assessment of the impact of the decision of the majority is hardly an overstatement.
It should also be noted that a change of condition, particularly where it arises from a heart attack, may not readily manifest itself. Here, the change occurred within approximately two years of the original attack. However, if, in a given case, there should be an award for the maximum period of 300 weeks for permanent partial disability arising from a work-related heart attack, because the claimant has two years after the last payment within which to file for a change of condition, an increase of compensation could conceivably be awarded as late as seven years after the employee last worked for the employer who experiences the cost.
I believe it is inappropriate for an appellate court to fashion new rules, particularly in such areas of the Workers’ Compensation Act as this, which involve public policy decisions best determined by the legislature. I vote to reverse the Court of Appeals and vacate the Commission’s award.
