Effects of valsartan compared to amlodipine on preventing type 2 diabetes in high-risk hypertensive patients: The VALUE trial

Context Type 2 diabetes is emerging as a major health problem, which tends to cluster with hypertension in individuals at high risk of cardiovascular disease. Objective To test for the first time the hypothesis that treatment of hypertensive patients at high cardiovascular risk with the angiotensin-receptor blocker (ARB) valsartan prevents new-onset type 2 diabetes compared with the metabolically neutral calcium-channel antagonist (CCA) amlodipine. Design Pre-specified analysis in the VALUE trial. Follow-up averaged 4.2 years. The risk of developing new diabetes was calculated as an odds ratio (OR) with 95% confidence intervals (CI) for different definitions of diabetes. Patients A sample of 9995 high-risk, non-diabetic hypertensive patients. Interventions Valsartan or amlodipine with or without add-on medication [hydrochlorothiazide (HCTZ) and other add-ons, excluding other ARBs, angiotensin-converting enzyme (ACE) inhibitors, CCAs]. Main outcome measure New diabetes defined as an adverse event, new blood-glucose-lowering drugs and/or fasting glucose > 7.0 mmol/l. Results New diabetes was reported in 580 (11.5%) patients on valsartan and in 718 (14.5%) patients on amlodipine (OR 0.77, 95% CI 0.69–0.87, P < 0.0001). Using stricter criteria (without adverse event reports) new diabetes was detected in 495 (9.8%) patients on valsartan and in 586 (11.8%) on amlodipine (OR 0.82, 95% CI 0.72–0.93, P = 0.0015). Conclusion Compared with amlodipine, valsartan reduces the risk of developing diabetes mellitus in high-risk hypertensive patients.

Endothelial Dysfunction in Salt-Sensitive Essential Hypertension

The aim of this study was to evaluate endothelium-dependent and -independent vasodilation, as well as endothelium biochemical markers, in a group of essential hypertensive patients classified on the basis of salt sensitivity. Changes in forearm blood flow in response to acetylcholine, sodium nitroprusside, and NG-monomethyl-l-arginine (L-NMMA) infusion were determined by means of strain-gauge plethysmography. Moreover, plasma and urinary concentrations of nitrates, cGMP, and endothelin were measured during low (50 mmol/d) and high (250 mmol/d) salt intake. Salt-sensitive hypertension was diagnosed in 26 patients who exhibited a significant increase in 24-hour mean blood pressure assessed by ambulatory blood pressure monitoring after 1 week of high salt intake. Nineteen patients were considered salt resistant. Compared with salt-resistant hypertensives, salt-sensitive patients presented a significant lower (P =0.005) maximal acetylcholine-induced vasodilation (21±6.3 versus 28±7.5 mL · 100 mL−1 · tissue · min−1). On the contrary, maximal sodium nitroprusside–induced vasodilation did not significantly differ between groups (22.4±4.5 versus 23.9±5.3 mL · 100 mL−1 · tissue · min−1). The decrease in maximal acetylcholine-induced vasodilation promoted by the coadministration of L-NMMA was significantly more pronounced in salt-resistant compared with salt-sensitive patients (P =0.003). Finally, high salt intake promoted a significant decrease in 24-hour urinary nitrate excretion in salt-sensitive patients (from 443±54 to 312±54 &mgr;mol/d;P =0.033) compared with salt-resistant hypertensives (from 341±50 to 378±54 &mgr;mol/d). We conclude that salt-sensitive hypertension is associated with endothelial dysfunction characterized by a defective endothelium-dependent vasodilation. Impairment of the l-arginine–nitric oxide pathway may be responsible for this abnormal endothelial response.

Stroke mortality and trends from 1990 to 2006 in 39 countries from Europe and Central Asia: implications for control of high blood pressure

AIMS The aim of the present study was to extend our understanding of international trends in stroke and major sequelae in Europe and countries peripheral to Europe by assessing: (1) current mortality rates, (2) the most recent 15-year prevalence trends, and (3) the relationship between systolic blood pressure in community surveys and national stroke mortality. METHODS AND RESULTS Data were obtained from the World Health Organization (WHO www.who.int/whosis/database/mort/table.cfm), and represent national vital statistics as reported by 39 countries (European and Central Asian countries) using a standard format and population-based cardiovascular surveys. Total numbers of deaths by stroke (International Classification of Diseases 430-438, 444) and the age, sex-adjusted incidence rates were obtained and grouped according to three standard demographic categories: A, B, and C (WHO). A Bayesian linear mixed effect model was fitted to the annual mortality rates. Higher rates of stroke mortality were observed for B and C group countries as compared with those countries belonging to Group A (e.g. Bulgaria 273.9 and 281.1; Israel 37.7 and 45.4 per 100 000 men and women, respectively). Even though the mortality rates within the country groupings were relatively similar, countries with marked deviation from the average were observed, mainly in Groups B and C. Stroke mortality decreased sharply in Group A during the period of study; conversely it had increased substantially in Group B and to a lesser extent in Group C. For both sexes markedly higher rates were noted moving from west to east, with some exceptions. CONCLUSION We have entered a period of rapidly increasing international inequality in stroke risk, where countries with low adult mortality in the latter 20th century extended their downward trend and countries with moderate as well as high mortality have on average seen unprecedented increases in death rates from stroke.

Renin-Angiotensin System Genetic Polymorphisms and Salt Sensitivity in Essential Hypertension

We evaluated the association between salt-sensitive hypertension and 3 different genetic polymorphisms of the renin-angiotensin system. Fifty patients with essential hypertension were classified as salt sensitive or salt resistant, depending on the presence or absence of a significant increase (P<0.05) in 24-hour ambulatory mean blood pressure (BP) after high salt intake. The insertion/deletion (I/D) angiotensin-converting enzyme (ACE) gene, the M235T angiotensinogen (AGT) gene, and the A1166C angiotensin II type 1 (AT1) receptor gene polymorphisms were determined with the use of standard polymerase chain reaction methods. Twenty-four (48%) patients with significantly increased (P<0.05) 24-hour mean BP with high salt intake (from 107.3+/-9.4 to 114.8+/-10.6 mm Hg) were classified as salt sensitive. In the remaining 26 patients (52%), high salt intake did not significantly modify 24-hour mean BP (from 107.6+/-10 to 107. 8+/-9 mm Hg), and they were classified as having salt-resistant hypertension. We did not find any significant association between either M235T AGT or A1166C AT1 receptor genotypes and the BP response to high salt intake. However, patients with essential hypertension homozygous for the insertion allele of the ACE gene (II) had a significantly higher BP increase with high salt intake (9. 8+/-8.1 mm Hg for systolic BP and 5.2+/-4.2 mm Hg for diastolic BP) than that observed in patients homozygous for the deletion allele (DD) (1.2+/-5.9 mm Hg for systolic BP; P=0.0118 and -0.2+/-4.2 mm Hg for diastolic BP; P=0.0274). Heterozygous patients (ID) exhibited an intermediate response. The prevalence of salt-sensitive hypertension also was significantly higher (P=0.012) in II (67%) and DI patients (62%) compared with DD hypertensives (19%). We conclude that a significant association exists between the I/D polymorphism of the ACE gene and salt-sensitive hypertension. Patients with II and DI genotypes have significantly higher prevalence of salt sensitivity than DD hypertensives.

Hypertension and atrial fibrillation: diagnostic approach, prevention and treatment. Position paper of the Working Group "Hypertension Arrhythmias and Thrombosis" of the European Society of Hypertension

Hypertension is the most common cardiovascular disorder and atrial fibrillation is the most common clinically significant arrhythmia. Both these conditions frequently coexist and their prevalence increases rapidly with aging. There are different risk factors and clinical conditions predisposing to the development of atrial fibrillation, but due its high prevalence, hypertension is still the main risk factor for the development of atrial fibrillation. Several pathophysiologic mechanisms (such as structural changes, neurohormonal activation, fibrosis, atherosclerosis, etc.) have been advocated to explain the onset of atrial fibrillation. The presence of atrial fibrillation per se increases the risk of stroke but its coexistence with high blood pressure leads to an abrupt increase of cardiovascular complications. Different risk models are available for the risk stratification and the prevention of thromboembolism in patients with atrial fibrillation. In all of them hypertension is present and is an important risk factor. Antihypertensive treatment may contribute to reduce this risk, and it seems some classes are superior to others in the prevention of new-onset atrial fibrillation and prevention of stroke. Antithrombotic treatment with warfarin is effective in the prevention of thromboembolic events, although quite recently, new classes of anticoagulants that do not require international normalized ratio monitoring have been introduced with promising results.

Ambulatory blood pressure monitoring in hypertensive patients with high cardiovascular risk: a cross-sectional analysis of a 20,000-patient database in Spain.

Objective To evaluate ambulatory blood pressure monitoring (ABPM) parameters in a broad sample of high-risk hypertensive patients. Methods The Spanish Society of Hypertension is developing a nationwide project in which more than 900 physicians send ABPM registries and corresponding clinical records to a central database via www.cardiorisc.com. Between June 2004 and July 2005 a 20 000-patient database was obtained; 17 219 were valid for analysis. Results We identified 6534 patients with high cardiovascular risk according to the 2003 European Society of Hypertension/European Society of Cardiology guidelines stratification score. Office blood pressure (BP) was 158.8/89.9 mmHg and 24-h BP was 135.8/77.0 mmHg. Patients with grade 3 BP in the office showed ambulatory systolic BP values less than 160 mmHg in more than 80%. A non-dipping pattern was observed in 3836 cases (58.7%), whereas this abnormality was present in 47.9% of patients with low-to-moderate risk [odds ratio (OR) 1.54; 95% confidence interval (CI) 1.45–1.64]. The prevalence of non-dippers was higher as ambulatory BP increased (≈ 70% when 24-h systolic BP > 155 mmHg) and was similar in both groups. At the lowest levels of BP (24-h systolic BP < 135 mmHg) a non-dipping pattern was more prevalent in high-risk cases (56.6 versus 45.7%; OR 1.51; 95% CI 1.40–1.64). Conclusion There was a remarkable discrepancy between office and ambulatory BP in high-risk hypertensive patients. The prevalence of a non-dipper BP pattern was almost 60%. In the lowest levels of ambulatory BP, high-risk patients showed a higher prevalence of non-dipping BP than lower-risk cases. These observations support the recommendation of a wider use of ABPM in high-risk hypertensive patients.
