Randomized trial of warfarin, aspirin, and clopidogrel in patients with chronic heart failure: the Warfarin and Antiplatelet Therapy in Chronic Heart Failure (WATCH) trial.

abstract：:In a porcine preparation of cardiac arrest, we demonstrated that there is a marked paradox of venous acidemia and arterial alkalemia. This paradox is related to decreased clearance of CO2 from the lungs when pulmonary blood flow is critically reduced. Accordingly, increased venous PCO2 rather than metabolic acidosis d...
