Improved insulin sensitivity by the angiotensin II-receptor blocker losartan is not explained by adipokines, inflammatory markers, or whole blood viscosity.

We have previously found improved insulin sensitivity after antihypertensive treatment with an angiotensin II-receptor blocker as compared with a calcium channel blocker in hypertensives. In this study, we compare the effect of these 2 principal different vasodilating agents on levels of adipokines, inflammatory variables, and whole blood viscosity in the same hypertensive patients with cardiovascular risk factors. We test whether potential differences in these variables might explain the difference seen in insulin sensitivity.

The effect of losartan versus atenolol on cardiovascular morbidity and mortality in patients with hypertension taking aspirin: the Losartan Intervention for Endpoint Reduction in hypertension (LIFE) study.

Objectives: We conducted a subgroup analysis in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study to determine whether aspirin interacted with the properties of losartan, an angiotensin-II receptor antagonist.

Background: Negative interactions between angiotensin-converting enzyme inhibitors and aspirin have been reported. There are no data reported from clinical trials about possible interactions between angiotensin-II receptor antagonists and aspirin.

Adrenal medullary overactivity in lean, borderline hypertensive young men.

Background: There may be a link among stress, adrenal medullary activation, and the development of hypertension. Obesity is characterized by sympathetic activation and predisposes to hypertension, but may be associated with low or normal adrenal medullary activity. We hypothesized that plasma epinephrine (E) levels and adrenal medullary responsiveness to mental stress are lower in overweight than in lean borderline hypertensive subjects.

High screening blood pressure is related to sympathetic nervous system activity and insulin resistance in healthy young men.

The cardiovascular metabolic syndrome is characterized by the presence of several cardiovascular risk factors, including blood pressure (BP) elevation. We aimed to study the relation between mental stress, plasma catecholamines, BP and BP responses to mental stress in healthy young Caucasian men selected from different levels of screening BP. We included 98 men with high and 22 men with normal screening BP.
