Cardiac β‐adrenoceptors and adenylyl cyclase activity in human left ventricular hypertrophy due to pressure overload

Humans with left ventricular hypertrophy (LVH) due to aortic stenosis, and patients without LVH undergoing heart surgery for mitral stenosis or coronary artery disease (controls). Both groups had normal systolic function and plasma catecholamine levels.
