Reduction in morning blood pressure is a key factor for ameliorating urinary albumin excretion in patients with morning hypertension irrespective of treatment regimen.

Background:  The Morning Hypertension and Angiotensin Receptor Blocker/Hydrochlorothiazide Combination Therapy (MAPPY) study has shown that losartan/hydrochlorothiazide (HCTZ) combination is superior to high-dose losartan in not only reducing morning systolic blood pressure (SBP) but also ameliorating urinary albumin excretion (UAE) after 3-month treatment. The purpose of the present study was to investigate factors associated with UAE reduction in on-treatment patients with morning hypertension.

Methods And Results:  A total of 95 patients registered in the MAPPY study were analyzed.

Endothelial function in subjects with isolated low HDL cholesterol: role of nitric oxide and circulating progenitor cells.

Epidemiologic studies have shown that a low level of high-density lipoprotein (HDL) cholesterol is a risk factor for cardiovascular diseases. The purpose of this study was to determine the contribution of isolated low HDL cholesterol to endothelial function. Thirty-nine subjects with low HDL cholesterol who had no other cardiovascular risk factors were selected from the 5,417 participants from our population.

Elevated circulating oxidized LDL levels in Japanese subjects with the metabolic syndrome.

In the present study, we examined the relationship between circulating oxidized low-density lipoprotein (LDL) and the metabolic syndrome in Japanese patients. Subjects who had no histories of coronary or peripheral artery disease and were taking no medications (n=119; age 57+/-10 years; male/female, 90:29) underwent a complete history and physical examination, determination of blood chemistries and oxidized LDL levels. In stepwise regression analysis, triglycerides (p=0.
