Johnson2 confirmed his findings and adopted the second possibility as an explanation, assuming that the blood is laden with impurities as a result of the renal disease, and that these poisons stimulate the arterioles to contract by way of the vasomotor nerves and so necessitate an hypertrophy of the left ventricle.
