The aim of this study was to compare the effects between calcium channel blockers and diuretics when used in combination with angiotensin II receptor blocker on aortic systolic blood pressure (BP) and brachial ambulatory systolic BP. We conducted a prospective, randomized, open-label, blinded end point study in 207 hypertensive patients (mean age: 68.4(More)
Arterial stiffness is a strong determinant of cardiovascular risk. Pulse wave velocity (PWV) and the augmentation index (AIx) are widely used as arterial stiffness indices. We studied the reproducibility of these indices and their association with cardiovascular risk factors in hypertensives. We measured brachial blood pressure (BP), brachial-ankle PWV(More)
Collagen metabolism in the extracellular matrix (ECM) is related to the pathogenesis of cardiovascular stiffness and remodeling in hypertension. We evaluated the association between collagen metabolism markers and the newly developed parameter, brachial-ankle pulse wave velocity (baPWV), in older hypertensive patients with left ventricular hypertrophy(More)
BACKGROUND Masked hypertension (MHT: normal office blood pressure [BP] + elevated BP out of the office) is a significant predictor of target organ damage and cardiovascular disease. The purpose of this study was to investigate the subclinical arterial damage in unmedicated subjects with MHT detected by home BP measurement. METHODS We recruited 282(More)
Diabetes and hypertension are potent risk factors for cerebrovascular disease. We studied the effects of an angiotensin II type 1 receptor blockade (ARB) on brain damage in hypertensives in relation to diabetes. We studied cerebral metabolism (by proton magnetic resonance spectroscopy) and hemodynamics (by phase-contrast magnetic resonance angiography)(More)
OBJECTIVE Ground-glass opacity (GGO) of the lung is being frequently detected by thin section computed tomography scan. However, the long term management of detected GGO is still unclear. To establish follow-up plans, we performed the clinical and radiological review to identify the factors that are closely associated with GGO growth. METHODS We(More)
Thromboxane A(2) (TXA(2) ) is a prostanoid formed by thromboxane synthase using the cyclooxygenase product, prostaglandin H(2), as the substrate. TXA(2) was shown to enhance tumor metastasis, but the underlying mechanism remains unclear. B16F1 melanoma cells were intravenously injected into TXA(2) receptor (TP) knockout mice (TP(-/-) ) and wild-type(More)
The lymphatic system is an important route for cancer dissemination, and lymph node metastasis (LNM) serves as a critical prognostic determinant in cancer patients. We investigated the contribution of COX-2-derived prostaglandin E2 (PGE2) in the formation of a premetastatic niche and LNM. A murine model of Lewis lung carcinoma (LLC) cell metastasis revealed(More)
BACKGROUND We aimed to test the hypothesis that the angiotensin II receptor blocker (ARB)/diuretic combination decreases the urinary albumin/creatinine ratio (UACR) to a greater extent than treatment with the ARB/calcium-channel blocker (CCB) combination through a mechanism related to a greater reduction of sleep blood pressure (BP). METHODS We conducted(More)
BACKGROUND Surgery for elderly patients with primary lung neoplasms has become relatively common as populations age; however, the high frequency of postoperative complications has prevented its broad application. Recently, the Japanese Respiratory Society proposed lung age (LA) as an index of lung function, but reports on the association between LA and the(More)
