Abstract The goal of treatment in stable coronary artery disease is to improve prognosis and quality of life of the patients. International Guidelines support revascularization procedures for symptomatic patients unresponsive to optimal medical treatment. Previous studies demonstrated, in fact, the therapeutic efficacy of coronary angioplasty in reducing angina and improving the functional capacity of these patients. The ORBITA study, recently published, challenged these assertions by demonstrating the lack of benefit of angioplasty over placebo in terms of effort tolerance in a population of patients with single-vessel coronary artery disease. What lesson could we learn from the ORBITA study?

The regression equation of the American College of Sports Medicine (ACSM) was a preferred method for estimating maximal oxygen consumption (VO2max). Recently, a more precise equation from the fitness registry and the importance of exercise national database (FRIEND) for healthy people was developed. This study compared VO2max estimated by the ACSM and FRIEND equations to VO2max directly measured in coronary artery disease (CAD) patients. Overall, 293 CAD patients who participated in cardiac rehabilitation between June 2015 and December 2018 were analyzed. Directly measured VO2max values were compared to the ACSM and FRIEND equations. The directly measured VO2max was significantly different from the estimated VO2max by ACSM equation (24.16 vs. 28.7 mL/kg/min, p < 0.001), which was overestimated by 20% in men and 16% in women. However, there was no statistically significant difference between the directly measured VO2max and the estimated VO2max by the FRIEND equation. (24.16 vs. 24.15 mL/kg/min, p = 0.986). In CAD patients, the estimated VO2max from the ACSM equation was significantly higher than the directly measured VO2max. In addition, estimated cardiorespiratory fitness (CRF) by the FRIEND equation showed similar results with directly measured CRF. As a result, the FRIEND equation can predict CRF more accurately than the ACSM.
