Pulmonary artery hypertension in severe aortic stenosis: incidence and mechanism.

abstract：BACKGROUND:Kidney failure causes anemia and is associated with a very high risk of coronary heart disease (CHD). Mildly to moderately decreased kidney function is far more common and also is associated with an elevated prevalence of anemia and CHD risk. Recent data suggest an even higher risk of CHD when both condition...
