Jerry L. Pope appeals from the judgment of the district court entered in favor of the Secretary of the Department of Health and Human Services denying him disability insurance and supplemental security income benefits under the Social Security Act, 42 U.S.C. §§ 423, 1381a (1982). The administrative law judge found that Pope had not engaged in substantial gainful activity since December 9, 1985 and that he was unable to perform his past relevant work. *1039 The ALJ concluded, however, that Pope did retain the residual functional capacity to perform sedentary work. Based on this finding, the AU denied benefits to Pope and the denial was affirmed by the district court. On appeal, Pope asserts that the AU failed to recognize the shift of the burden of proof to the Secretary after finding that Pope could not resume his regular work. Pope also asserts that substantial evidence does not support the Secretary’s determination that he can perform a full range of sedentary work but rather substantial evidence establishes that he does not have such capability and therefore it is error to rely on the Medical-Vocational Guidelines. We reverse and'remand to the Secretary for further consideration.
I.
Pope, now forty-five years old, has a history of heart disease which first became evident in June or July 1982. On April 26, 1985, quadruple coronary artery bypass surgery was performed on him. On December 16, 1985, Pope applied for disability benefits and supplemental security income with the Secretary of the Department of Health and Human Services. The Secretary denied benefits to Pope and a hearing before an AU followed on October 22, 1986. The AU concluded that Pope was not entitled to benefits, and Pope subsequently requested review by the Appeals Council of the Social Security Administration. The Appeals Council noted that although the AU did not explicitly state that the burden of proof had shifted because of Pope’s inability to perform his past work, the AU nevertheless met his burden of proof by correctly utilizing the Medical-Vocational Guidelines, 20 C.F.R. pt. 404, subpt. P, app. 2. The Appeals Council denied Pope’s request for review which made the AU’s decision the final decision of the Secretary. Pope appealed the Secretary’s decision to the district court under 42 U.S.C. § 405(g). The district court held that the outcome of the case was clear regardless of who bore the burden of proof and therefore denied Pope’s claim for benefits. This appeal followed. Our task is to determine whether the Secretary’s decision is supported by substantial evidence on the record as a whole. 42 U.S.C. § 405(g).
At the hearing before the AU, Pope presented evidence of the medical opinion of his treating physician, Dr. Martin Aro-now. The AU found that Dr. Aronow was not entirely consistent in his opinion of Pope’s disability status. On two occasions, January 9, 1986 and April 2, 1986, Dr. Aronow stated that Pope was totally disabled. On December 13, 1985, however, on the date of Pope’s treadmill stress test, he found that Pope demonstrated a normal physical work capacity with no significant arrhythmia, unremarkable EKG, and no is-chemic lesion identified with submaximal stress. The AU also noted that Dr. Aro-now’s subsequent opinion of disability was not supported by the findings of the Cardiac Surgery Associates. In a letter dated January 13, 1986, based on a June 10, 1985 examination, the Cardiac Surgery Associates, of which Pope’s surgeon, Dr. Richard Toon is a member, stated that Pope was walking over two miles per day without difficulty and that there were no long term limitations imposed on his activities.
The AU found that Pope was a credible witness who testified openly and candidly about his condition. The AU acknowledged Pope’s allegation of constant pressure in his chest and his claim that he started to experience angina when he became active. He further recognized Pope’s testimony that he could walk 200 feet without chest discomfort, stand four to five minutes, use his hands and arms, although not repetitively, lift five to ten pounds without problem, and sit without problem. The AU found that these restrictions would not preclude sedentary work.
The AU found that Pope had not engaged in substantial gainful activity since December 9, 1985 and was unable to perform his past relevant work as fire inspector, safety inspector, police officer or security supervisor. The AU found, however, that Pope had the residual functional capacity to satisfy the physical exertion requirements of work except for prolonged walking and standing, repeated bending, and lifting weights in excess of ten pounds. *1040 The AU determined that Pope retained the residual functional capacity to perform the full range of sedentary work and concluded that he was not disabled.
II.
Pope asserts as error the AU’s failure to expressly recognize that the burden of proof shifts to the Secretary upon a finding that he could not perform his past work. The Secretary concedes that the AU did not expressly recognize the burden shift and acknowledges that our holdings require such a burden shift. Relying on
Kirksey v. Heckler,
As the Secretary recognizes, we have frequently declared that the AU must expressly acknowledge the shift in the burden of proof and if the AU does not do so, we will not assume that the AU implicitly shifted the burden of proof. This failure to shift the burden of proof constitutes reversible error unless all of the evidence is so strongly against the claimant's position that a proper allocation of the burden of proof would not have changed the outcome.
Struempler v. Bowen,
Upon examining the record before us, we cannot conclude that the evidence is so strongly against Pope’s position that a proper allocation of the burden of proof would not have changed the outcome.
Struempler,
The record contains other evidence, however, which minimizes the effect of these inconsistencies. The report from Cardiac Surgery Associates which states that Pope was walking over two miles per day without difficulty and with no long term limitations imposed on his activities, although dated January 13, 1986, was actually based on a June 10, 1985 examination. In addition, this report specifically referred the disability determination personnel to Dr. Aronow, as Pope’s personal physician, for more recent evaluation of Pope’s condition. In a report dated December 11, 1985, Dr. Toon of the Cardiac Surgery Associates stated that Pope had done well until two weeks earlier when Pope again noticed the onset of angina pains and that Pope was able to last only one minute on the treadmill. He further stated that the left anteri- or descending artery was heavily diseased as it had been at the time of surgery. Dr. Toon recommended medical therapy and indicated that if therapy was not successful, repeat surgery should be considered.
While Dr. Aronow expressed an opinion based on the December 13, 1985 treadmill test that Pope demonstrated a normal physical work capacity, he also stated that the treadmill test was inconclusive one day later, on December 14, 1985. In his letter dated January 9, 1986, Dr. Aronow reported that Pope had not had a good result from his bypass surgery, continued to be very symptomatic in spite of medications, and was at risk for myocardioinfarction in the future. Dr. Aronow stated that, considering Pope’s age, he would probably require a second bypass procedure in the future, although it should be delayed as long as possible. He also reported that *1041 Pope was experiencing angina with minimal physical activity in spite of medications. Dr. Aronow concluded that he should be considered completely and totally disabled for all types of work now and in the future.
Under these circumstances, the AU’s rationale for discrediting Dr. Aronow’s opinion is not based upon substantial evidence on the record as a whole. This state of the record prevents us from concluding that the evidence presented is so strongly against Pope’s position that a proper allocation of the burden of proof would not have changed the outcome. Accordingly, we must remand to the Secretary for further consideration with a clear acceptance of the burden shift.
III.
We further observe that the Secretary should carefully consider the regulations defining residual functional capacity upon remand. In particular, the Secretary must establish that there is substantial evidence which supports a finding that the claimant can perform the requisite physical acts “day in and day out, in the sometimes competitive and stressful conditions in which real people work in the real world.”
McCoy v. Schweiker,
Finally, we observe that the testimony of the treating physician, Dr. Aronow, must be accorded its proper weight upon remand. To reject the opinion of the treating physician, the Secretary must establish that there is substantial evidence on the record as a whole which leads to such a result.
Ward v. Heckler,
We reverse and remand to the Secretary for further proceedings consistent with this opinion.
