Renoprotective effect and cost-effectiveness of using benidipine, a calcium channel blocker, to lower the dose of angiotensin receptor blocker in hypertensive patients with albuminuria.

In hypertensive patients with chronic renal disease, angiotensin receptor blockers (ARBs) are among the first-line drugs, and calcium channel blockers (CCBs) are recommended as a second line. We examined the effects of two therapeutic strategies using ARBs and benidipine, a CCB, on blood pressure (BP), urinary albumin excretion (UAE), and cost-effectiveness in hypertensive patients with albuminuria. Patients whose BP was 140/90 mmHg or higher despite treatment with low- or medium-dose ARBs were assigned randomly to two groups.

Multiple papillary fibroelastomas of the aortic valve: case report.

Papillary fibroelastoma is the third most common primary tumor of the heart and most commonly involve the cardiac valves. Most papillary fibroelastomas do not cause symptoms and they are usually incidental findings by routine echocardiography or at autopsy. However, multiple papillary fibroelastomas are extremely rare.

Oxidative stress in the Dahl salt-sensitive hypertensive rat.

Oxidative stress has been proposed as important in the pathogenesis of hypertension. Measurement of 8-iso prostaglandin F2alpha (8-ISO) is introduced for evaluating oxidative stress in vivo. 8-ISO is the major urinary metabolite of F2-isoprostanes and is formed nonenzymatically from the attack of superoxide radicals on arachidonic acid.
