Abstract

Objective: The New York Heart Association (NYHA) classification is recommended for grading symptoms of chronic heart failure and is a powerful prognostic marker. Patient-rated NYHA (Pa-NYHA) and physician-rated NYHA (Dr-NYHA) class have never been compared directly, and it is unknown whether they carry similar prognostic significance. Methods and Results: NYHA class was rated independently by a physician and patient in 1752 patients referred with suspected heart failure. Pa-NYHA and Dr-NYHA varied by 1 class in 37.1% cases and by 2 classes in 12.8% cases. Mean Dr-NYHA and Pa-NYHA were higher in women than men (1.98 vs 1.89, P = .016; 2.17 vs 2.02, P = .002) despite less cardiac disease. Dr-NYHA correlated more with 6-minute walk test distance and severity of left ventricular systolic dysfunction than Pa-NYHA (Spearman's ρ: −0.53 vs −0.44 and 0.32 vs 0.16). Dr-NYHA better predicted mortality when compared with Pa-NYHA (log-rank: χ2 = 105 vs 46, both P < .001). Conclusion: Patients rate NYHA differently from physicians, and women rate NYHA differently from men. Dr-NYHA relates more strongly to survival and severity of left ventricular systolic dysfunction, suggesting that for physicians the NYHA classification may have become a “heart failure severity score” and not as was intended, purely a measure of a patient's symptoms and functional status.
