Is hemodynamic , not ventilatory , inefficiency associated with high VE/VCO2 slope in repaired , noncyanotic congenital heart disease?
A high VE/VCO₂ slope observed in patients with repaired, noncyanotic CHD seems not to depend on excessive ventilation but on hypoperfusion due to impaired cardiac output response to incremental exercise. This finding should focus researchers' attention mainly on the heart when addressing exercise pathophysiology of this patient population.
Rheumatologist care is not more costly than generalist care for patients with RA. Important differences (especially in the use of laboratory tests) become apparent when the type of care provided as well as the specialty of the provider are considered in the analyses.
