Effects of eprosartan on diastolic function and neurohormones in patients with hypertension and diastolic dysfunction.

Objective: To compare the effects of an angiotensin receptor blocker(ARB)-based regimen versus a non-ARB based regimen on diastolic function and neurohormones in patients with hypertension and diastolic dysfunction.

Methods: 97 patients with a systolic blood pressure (SBP) > or =140 mmHg, a left ventricular ejection fraction >0.50, and echocardiographic evidence of diastolic dysfunction were randomly assignment to open-label treatment with eprosartan (with other anti-hypertensives; n = 47) or other anti-hypertensives alone (n = 50).

Advanced glycation end-products, anti-hypertensive treatment and diastolic function in patients with hypertension and diastolic dysfunction.

Aims: To investigate the relationship between advanced glycation end-products (AGEs) and diastolic function and the response to blood pressure treatment in patients with hypertension and diastolic dysfunction.

Methods And Results: Data were analysed from 97 patients (aged 65 +/- 10 years, 36% male) who were randomly assigned to 6 months open-label treatment with either eprosartan on top of other anti-hypertensive drugs (n = 47) or other anti-hypertensive drugs alone (n = 50). Tissue AGE accumulation was measured using a validated skin-autofluorescence (skin-AF) reader (n = 26).

The influence of clinical characteristics, laboratory and inflammatory markers on 'high on-treatment platelet reactivity' as measured with different platelet function tests.

High on-clopidogrel platelet reactivity (HCPR) and high on-aspirin platelet reactivity (HAPR) are independently associated with an increased risk of atherothrombotic events. However, despite this positive correlation, the definitions of both HCPR and HAPR vary largely throughout studies and between different platelet function assays. The aim of the present study was to explore clinical and laboratory parameters that are associated with HCPR and HAPR as measured with different platelet function tests.

Plasma matrix metalloproteinase-9 and ACE-inhibitor-induced improvement of urinary albumin excretion in non-diabetic, microalbuminuric subjects.

Introduction: Elevated plasma matrix metalloproteinase-9 (MMP-9) levels have been suggested to precede the development of microalbuminuria. As angiotensin-converting enzyme (ACE) inhibitors effectively reduce urinary albumin excretion (UAE), in the present study we have investigated the potential association of plasma MMP-9 levels with UAE and treatment effects of ACE-inhibition.

Material And Methods: In a placebo-controlled randomised trial we determined plasma MMP-9 levels at baseline and after three months of randomisation to either placebo (n=202) or fosinopril (20 mg/day, n=204) treatment.

Predictors of angiotensin-converting enzyme inhibitor-induced reduction of urinary albumin excretion in nondiabetic patients.

Urinary albumin excretion is a predictor for cardiovascular mortality and morbidity. We investigated which parameters determine baseline urinary albumin excretion in nondiabetic subjects, without renal disease. In addition, we evaluated the parameters that predict the albuminuria-lowering efficacy of an angiotensin-converting enzyme inhibitor.

High prevalence of microalbuminuria in chronic heart failure patients.

Background: Microalbuminuria is associated with increased risk for cardiovascular morbidity and mortality. However, the relation between microalbuminuria and chronic heart failure has not been well described yet. In this cross-sectional study, we aim to evaluate the prevalence of microalbuminuria and the association with neurohormonal parameters in severe chronic heart failure patients.

Levels of hematopoiesis inhibitor N-acetyl-seryl-aspartyl-lysyl-proline partially explain the occurrence of anemia in heart failure.

Background: Anemia is common in patients with chronic heart failure (CHF) and is associated with a poor prognosis. However, only a minority of patients with CHF have impaired renal function or underlying hematinic deficiencies. It has been shown that inhibition of the renin-angiotensin system is associated with the development of anemia.

Addition of an angiotensin receptor blocker to full-dose ACE-inhibition: controversial or common sense?

Both angiotensin-converting enzyme (ACE)-inhibitors and angiotensin receptor blockers (ARBs) interfere with the activity of the renin-angiotensin system (RAS) in a different way. Theoretically, one might expect beneficial effects when they are used in combination, as a more complete suppression of the RAS can be achieved. But can this additional effect still be seen in patients on full-dose ACE-inhibition? Several controlled trials demonstrated that combination therapy can have additional benefits in hypertensive patients, in chronic heart failure patients, and in both diabetic and non-diabetic nephropathy patients.

Mild preoperative renal dysfunction as a predictor of long-term clinical outcome after coronary bypass surgery.

Background: Renal dysfunction is a prognostic marker in patients with cardiovascular disease. However, no long-term follow-up studies on the influence of mild renal dysfunction on mortality in patients undergoing coronary bypass grafting have been reported. Therefore, we aimed to identify the significance of preoperative (mild) renal dysfunction as a long-term predictor of clinical outcome after coronary bypass surgery.
