Role of neurohumoral control of the circulation in determining exercise capacity in patients with heart failure.

abstract：:Most panels that develop clinical practice guidelines are poorly equipped to address resource allocation or cost issues associated with management options. This risks neglect, arbitrariness, lack of transparency, and methodological flaws in consideration of resource allocation. We provide recommendations for guideline...
