Comparison of arterial functional evaluations as a predictor of cardiovascular events in hypertensive patients: the Non-Invasive Atherosclerotic Evaluation in Hypertension (NOAH) study.

Increased arterial stiffness and impaired vasodilator response have been associated with cardiovascular events in high-risk patients. However, whether arterial changes predict the occurrence of hypertensive complications is still unclear. Therefore, we designed a hospital-based cohort study to examine the prognostic impact of arterial functional changes on stroke and cardiovascular diseases in hypertensive patients.

Renal-protective effect of T-and L-type calcium channel blockers in hypertensive patients: an Amlodipine-to-Benidipine Changeover (ABC) study.

Both strict blood pressure control and efferent artery dilatation are critical in reducing proteinuria, which in turn helps to regulate blood pressure. Benidipine, an L- and T-type calcium channel blocker, has the potential for increased effectiveness compared with L-type-dominant calcium channel blockers such as amlodipine. Therefore, we evaluated blood pressure and proteinuria after changeover from amlodipine to benidipine in poorly controlled hypertensive patients.

Clinical usefulness and limitations of brachial-ankle pulse wave velocity in the evaluation of cardiovascular complications in hypertensive patients.

The goal of this study was to clarify the clinical usefulness and limitations of brachial-ankle pulse wave velocity (PWV) to evaluate hypertensive complications, in comparison with carotid-femoral PWV. Patients with essential hypertension (n=296, male/female=161/135; age=61.1+/-0.

Evaluation of morning blood pressure elevation and autonomic nervous activity in hypertensive patients using wavelet transform of heart rate variability.

To evaluate morning autonomic nervous activity and blood pressure profiles in hypertensive patients by analyzing heart rate variability and ambulatory blood pressure. Data from 82 patients with untreated essential hypertension were analyzed. We evaluated the 24-h profile of blood pressure and that of indices of autonomic nervous activity, i.

Genetic influences of beta-adrenoceptor polymorphisms on arterial functional changes and cardiac remodeling in hypertensive patients.

Three subtypes of beta-adrenoceptor, beta1, beta2 and beta3, are involved in the sympathetic nervous system, which plays an important role in the development of hypertension and hypertensive complications. These complications can include left ventricular hypertrophy and arterial stiffness, which are reported risk factors for cardiovascular diseases. We designed clinical trials to clarify the association between hypertensive complications and beta-adrenoceptor single nucleotide polymorphisms in essential hypertension.

Serum interleukin-15 concentration in patients with essential hypertension.

Background: Interleukin (IL)-15 is one of the cytokines produced by neutrophils and monocytes/macrophages, and its expression is found immunohistochemically in inflammatory cells adjacent to vulnerable atherosclerotic plaques. However, the influence of systemic IL-15 on cardiovascular disease is still unclear. Therefore, we designed clinical investigations to clarify the relationship between cardiovascular complications and serum IL-15 levels.
