Background: In outpatient center-based cardiac rehabilitation (O-CBCR), moderate-intensity continuous training (MICT) based on the anaerobic threshold (AT) determined by cardiopulmonary exercise stress testing is recommended. However, it is unclear whether differences in exercise intensity within the MICT domain affect peak oxygen uptake (%peakV̇O2).Methods and Results: We retrospectively evaluated patients who underwent O-CBCR at Japan Community Healthcare Organization Osaka Hospital. Those treated with the constant-load method were designated as Group A (n=38), whereas those treated with the variable-load method were designated as Group B (n=48). Although the change in exercise intensity was significantly greater in Group B by approximately 4.5 W, the change in %peakV̇O2was not significantly different between groups. Group A had a significantly longer exercise time than Group B (by approximately 4–5 min). No deaths or hospitalizations occurred in either group. The percentage of episodes with exercise cessation was similar between the 2 groups, but the percentage of episodes with load reduction was significantly higher in Group B, mostly because of the increased heart rate.Conclusions: In supervised MICT based on AT, the variable-load method increased exercise intensity more than the constant-load method without severe complications, but did not improve %peakV̇O2.

Takayasu arteritis (TAK) is a rare disease characterized by inflammation of large blood vessels, which results in vascular stenosis, occlusion, and aneurysm formation. The principal treatment has been glucocorticoids, but the recent emergence of biological disease-modifying anti-rheumatic drugs (bDMARDs), represented by tocilizumab (TCZ), has significantly changed the treatment landscape. Both cardiologists and cardiovascular surgeons will encounter patients receiving these drugs who require catheterization, other invasive procedures, or surgery. Several bDMARDs have shown promise against TAK in clinical studies and their use is expected to increase in the future. Janus kinase inhibitors may also be effective. Here, we review the evidence supporting the use of TCZ and other immunosuppressants in TAK and provides an update on their status as well as the relevant guidelines.
