Is the G-231A polymorphism in the endothelin-A receptor gene associated with lower aortic pressure in patients with dilated cardiomyopathy?
Our results suggest an association of genetic variation in the ET(A) receptor gene with aortic pressure in patients with DCM.
None of the tested methods simultaneously improved the correlation to MWT, remained simple enough to be scored by mental calculation and ranged between intuitive minimal and maximal values. The original empirical scoring seems a good compromise between accuracy and simplicity.
