Abstract
Heart failure is a complex medical syndrome that is attributed to a number of risk factors; nevertheless, its clinical presentation is quite similar among the different etiologies. Heart failure displays a rapidly increasing prevalence due to the aging of the population and the success of medical treatment and devices. The pathophysiology of heart failure comprises several mechanisms, such as activation of neurohormonal systems, oxidative stress, dysfunctional calcium handling, impaired energy utilization, mitochondrial dysfunction, and inflammation, which are also implicated in the development of endothelial dysfunction. Heart failure with reduced ejection fraction is usually the result of myocardial loss, which progressively ends in myocardial remodeling. On the other hand, heart failure with preserved ejection fraction is common in patients with comorbidities such as diabetes mellitus, obesity, and hypertension, which trigger the creation of a micro-environment of chronic, ongoing inflammation. Interestingly, endothelial dysfunction of both peripheral vessels and coronary epicardial vessels and microcirculation is a common characteristic of both categories of heart failure and has been associated with worse cardiovascular outcomes. Indeed, exercise training and several heart failure drug categories display favorable effects against endothelial dysfunction apart from their established direct myocardial benefit.

Münzel T, Gori T. Nebivolol: the somewhat-different beta-adrenergic receptor blocker. J Am Coll Cardiol 2009; 54:1491-9.

Abstract
Although its clinical use in Europe dates almost 10 years, nebivolol is a beta-blocker that has been only recently introduced in the U.S. market. Like carvedilol, nebivolol belongs to the third generation of beta-blockers, which possess direct vasodilator properties in addition to their adrenergic blocking characteristics. Nebivolol has the highest beta(1)-receptor affinity among beta-blockers and, most interestingly, it substantially improves endothelial dysfunction via its strong stimulatory effects on the activity of the endothelial nitric oxide synthase and via its antioxidative properties. Because impaired endothelial activity is attributed a major causal role in the pathophysiology of hypertension, coronary artery disease, and congestive heart failure, the endothelium-agonistic properties of nebivolol suggest that this drug might provide additional benefit beyond beta-receptor blockade. Although lesser beta-blocker-related side effects have been reported in patients with chronic obstructive pulmonary disease or impotence taking nebivolol, side effects and contraindications overlap those of other beta-blockers. Clinically, this compound has been proven to have antihypertensive and anti-ischemic effects as well as beneficial effects on hemodynamics and prognosis in patients with chronic congestive heart failure. Further studies are now necessary to compare the benefit of nebivolol with that of other drugs in the same class and, most importantly, its prognostic impact in patients with hypertension.

Abstract
Nebivolol is a third generation beta-blocker. It is highly selective for the beta1-adrenoceptor, and has additional nitric oxide-mediated vasodilating and antioxidant properties, along with a favourable metabolic profile. Nebivolol is well tolerated by patients with hypertension and heart failure. Although several smaller studies were conducted with nebivolol in hypertensive patients, no large randomised clinical trials have been performed to prove efficacy on hard clinical end points. In patients with heart failure, a large mortality/morbidity trial was conducted, and nebivolol was shown to reduce the composite end point of mortality and hospitalisations. Nebivolol is registered, in Europe, for mild-to-moderate, uncomplicated hypertension and mild-to-moderate heart failure; and outside Europe, for hypertension. This review describes experimental and clinical data regarding this selective beta-blocker with vasodilating and antioxidant effects.

Abstract
BACKGROUND Genetic polymorphisms of beta3-adrenergic receptor (AR) Trp64Arg and beta2-AR Gln27Glu may result in significant change in the functions of these receptors. The aims of the present study were to investigate the association between Trp64Arg, Arg16Gly and Gln27Glu polymorphisms and the susceptibility to obesity and hypertension in a Chinese population. METHODS A total of 437 Chinese subjects including 149 obese hypertensive patients, 139 non-obese essential hypertensive patients, and 149 non-obese normotensive healthy controls were enrolled in the study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific (AS)-PCR assays were used to identify Trp64Arg, Arg16Gly, and Gln27Glu genotypes. RESULTS The allele frequencies of 64Arg and 27Glu in the obese hypertensive group were 0.178 and 0.128, respectively. Both were significantly higher than in the non-obese hypertensive and the control groups (p<0.05). Further analysis showed that this association existed only in male hypertensive patients. CONCLUSIONS These data reveal that frequencies of beta3-AR 64Arg and beta2-AR 27Glu were significantly higher in our obese hypertensive patients than in the non-obese hypertensive population and healthy controls. beta3-AR Trp64Arg and beta2-AR Gln27Glu genetic polymorphisms are associated with obesity in Chinese male hypertensive patients.

Abstract
Decreased nitric oxide synthase (NOS) activity induces left ventricular hypertrophy (LVH), but the transcriptional pathways mediating this effect are unknown. We hypothesized that specific NOS isoform deletion (NOS3 or NOS1) would activate different transcriptional programs in LVH. We analyzed cardiac expression profiles (Affymetrix MG-U74A) from NOS-/- mice using robust multi-array average (RMA). Of 12,422 genes analyzed, 47 genes were differentially expressed in NOS3-/- and 67 in NOS1(-/-) hearts compared with wild type (WT). Only 16 showed similar changes in both NOS-/- strains, most notably decreased heat-shock proteins (HSP10, 40, 70, 86, 105). Hypertrophied NOS1-/- hearts had unique features, including decreased myocyte-enriched calcineurin interacting protein and paradoxical downregulation of fetal isoforms (alpha-skeletal actin and brain natriuretic peptide). Cluster analyses demonstrated that NOS1 deletion caused more pronounced changes in the myocardial transcriptome than did NOS3 deletion, despite similar cardiac phenotypes. These findings suggest that the transcriptional basis for LVH varies depending on the inciting biochemical stimulus. In addition, NOS isoforms appear to play distinct roles in modulating cardiac structure.

Abstract
dl-Nebivolol has a beta(1)-adrenergic blocking property and l-nebivolol has an endothelial-dependent vasodilating property, sp that a racemic mixture, deltal-nebivolol, shows both properties. This study examined the effect of dl-nebivolol on ischemic myocardium in anesthetized open chest dogs. Ischemia was induced for 3 min by ligating the left anterior descending coronary artery 10 min after IV injection of vehicle, dl-nebivolol (0.03, 0.1, and 0.3 mg/kg), or d- or l-nebivolol (0.15 mg/kg). Ischemia significantly decreased the levels of ATP, creatine phosphate, and fructose-1,6-diphosphate and increased those of ADP, AMP, hexose monophosphates, and ratio of [lactate]/[pyruvate]. dl-Nebivolol at higher doses significantly attenuated some metabolic changes caused by ischemia. Although neither enantiomers significantly affected these ischemia-induced metabolic changes, d-nebivolol appeared to attenuate adenine nucleotide reduction due to ischemia. Pretreatment with Nw-nitro-l-arginine methyl ester did not abolish the restoration of ischemia-induced myocardial metabolic changes by dl-nebivolol. In conclusion, dl-nebivolol lessens ischemic derangement of myocardial metabolism, and the effects may be due mainly to its beta-adrenergic blocking property but not to endothelium-dependent vasorelaxing property.

Abstract
Despite recent therapeutic advances, the prognosis for patients with heart failure remains dismal. Unchecked neurohumoral excitation is a critical element in the progressive clinical deterioration associated with the heart failure syndrome, and its peripheral manifestations have become the principal targets for intervention. The link between peripheral systems activated in heart failure and the central nervous system as a source of neurohumoral drive has therefore come under close scrutiny. In this context, the forebrain and particularly the paraventricular nucleus of the hypothalamus have emerged as sites that sense humoral signals generated peripherally in response to the stresses of heart failure and contribute to the altered volume regulation and augmented sympathetic drive that characterize the heart failure syndrome. This brief review summarizes recent studies from our laboratory supporting the concept that the forebrain plays a critical role in the pathogenesis of ischemia-induced heart failure and suggesting that the forebrain contribution must be considered in designing therapeutic strategies. Forebrain signaling by neuroactive products of the renin-angiotensin system and the immune system are emphasized.
