Efficacy and safety of mineralocorticoid receptor antagonists for the treatment of low-renin hypertension: a systematic review and meta-analysis. J Hum Hypertens 2024; 38:383-392. [PMID: 38200100 PMCID: PMC11076210 DOI: 10.1038/s41371-023-00891-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 12/14/2023] [Accepted: 12/21/2023] [Indexed: 01/12/2024]
Abstract
Hypertension is the leading risk factor for premature death. The optimal treatment of low-renin hypertension (LRH), present in 30% of hypertensive individuals, is not known. LRH likely reflects a state of excess salt, expanded volume and/or mineralocorticoid receptor (MR) activation. Therefore, targeted treatment with MR antagonists (MRA) may be beneficial. The objective of this systematic review was to assess the efficacy of MRA therapy in LRH. MEDLINE, Embase and Cochrane databases were searched for randomised controlled trials of adults with LRH that compared the efficacy of MRA to placebo or other antihypertensive treatments. Risk of bias was assessed using the Cochrane risk of bias tool. A meta-analysis was performed using a random-effects model to estimate the difference in blood pressure and the certainty of evidence was assessed using the GRADE approach. The protocol is registered on PROSPERO (CRD42022318763). From the 1612 records identified, 17 studies met the inclusion criteria with a total sample size of 1043 participants. Seven studies (n = 345) were assessed as having a high risk of bias. Meta-analysis indicated that MRA reduced systolic blood pressure by -6.8 mmHg (95% confidence interval -9.6 to -4.1) and -4.8 mmHg (95% confidence interval -11.9 to 2.4) compared to angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARB) and diuretics. The certainty of the evidence was assessed as moderate and very low, respectively. The findings of this systematic review suggest that MRA is effective in lowering blood pressure in LRH and may be better than ACEi/ARB. Translation to clinical practice is limited by the uncertainty of evidence.

Abstract
Primary aldosteronism (PA) is the most frequent cause of secondary hypertension (HT), and is associated with a higher cardiometabolic risk than essential HT. However, PA remains underdiagnosed, probably due to several difficulties clinicians usually find in performing its diagnosis and subtype classification. The aim of this consensus is to provide practical recommendations focused on the prevalence and the diagnosis of PA and the clinical implications of aldosterone excess, from a multidisciplinary perspective, in a nominal group consensus approach by experts from the Spanish Society of Endocrinology and Nutrition (SEEN), Spanish Society of Cardiology (SEC), Spanish Society of Nephrology (SEN), Spanish Society of Internal Medicine (SEMI), Spanish Radiology Society (SERAM), Spanish Society of Vascular and Interventional Radiology (SERVEI), Spanish Society of Laboratory Medicine (SEQC(ML)), Spanish Society of Anatomic-Pathology, Spanish Association of Surgeons (AEC).

Factors Associated with the Antihypertensive Effect of Esaxerenone and Serum Potassium Elevation: A Pooled Analysis of Seven Phase III Studies. Adv Ther 2023; 40:1242-1266. [PMID: 36662393 PMCID: PMC9988784 DOI: 10.1007/s12325-022-02393-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 11/29/2022] [Indexed: 01/21/2023]
Abstract
INTRODUCTION This study investigated factors associated with the antihypertensive effects of esaxerenone and the incidence of serum potassium elevation in patients with hypertension. METHODS Using pooled data from seven phase III studies, the study analyzed factors associated with changes in office systolic (SBP) and diastolic (DBP) blood pressure from baseline to 12 weeks, and factors associated with incidence of serum potassium levels ≥ 5.5 mEq/L in esaxerenone-treated patients. RESULTS Overall, 1466 and 1472 patients were included in the full analysis and safety analysis sets, respectively. Male sex (4.02/2.40 mmHg), weight ≥ 78.4 kg (4.62/2.09 mmHg), hypertension duration ≥ 10 years (2.66/1.71 mmHg), prior antihypertensive treatment (2.38/1.40 mmHg), plasma aldosterone concentration ≥ 120 pg/mL (1.66/1.17 mmHg), urinary albumin-to-creatinine ratio (UACR) ≥ 300 mg/gCr (8.94/4.85 mmHg) or 30-299 mg/gCr (5.17/4.15 mmHg), and smoking (2.62/1.27 mmHg) were associated with mean changes in SBP and DBP. Fasting blood glucose ≥ 126 mg/dL (- 2.73 mmHg) was associated with the mean change in SBP only, and older age (65-74 years, - 2.12 mmHg; and ≥ 75 years, - 3.06 mmHg) with mean change in DBP only. Factors significantly associated with incidence of serum potassium levels ≥ 5.5 mEq/L were higher baseline serum potassium (≥ 4.5 mEq/L, odds ratio [OR] 6.702); lower estimated glomerular filtration rate (≥ 90 mL/min/1.73 m2, OR 0.148; 60-89 mL/min/1.73 m2, OR 0.331 vs 30-59 mL/min/1.73 m2, respectively); higher UACR (30-299 mg/gCr, OR 7.317); higher DBP (≥ 100 mmHg, OR 3.248); and grade I hypertension (OR 2.168). CONCLUSION Esaxerenone is effective in patients with a broad range of backgrounds, though some factors may predict increased benefit. Regarding elevated serum potassium, careful therapeutic management is recommended for patients with higher baseline serum potassium and reduced renal function.

Abstract
INTRODUCTION Clinical data of esaxerenone in hypertensive patients with diabetic kidney disease (DKD) are lacking. We evaluated the efficacy and safety of esaxerenone in patients with DKD and an inadequate response to blood pressure (BP)-lowering treatment. METHODS In this multicenter, open-label, prospective study, patients were divided into urinary albumin-to-creatinine ratio subcohorts (UACR < 30, 30 to < 300, and 300 to < 1000 mg/gCr). Esaxerenone was initiated at 1.25 mg/day and followed by incremental dose escalation based on BP and serum potassium level monitoring. The treatment period was 12 weeks. The primary endpoint was change in morning home systolic BP/diastolic BP (SBP/DBP) from baseline to end of treatment (EOT). Secondary endpoints included achievement rate of target BP, change in UACR from baseline, and safety. RESULTS In total, 113 patients were enrolled. Morning home SBP/DBP significantly decreased from baseline to EOT in the total population (- 11.6/- 5.2 mmHg, both p < 0.001) and in all UACR subcohorts (all p < 0.001). The target BP achievement rate was 38.5%. Significant reductions in bedtime home and office BPs were also shown in the total population and all UACR subcohorts. UACR significantly improved from baseline to EOT in the total (- 50.9%, p < 0.001) and all UACR subcohorts (all p < 0.001). Incidence of serum potassium elevation as drug-related treatment emergent adverse events was 2.7%. The change from baseline in estimated glomerular filtration rate (eGFR) was - 4.8 mL/min/1.73 m2. CONCLUSION Esaxerenone demonstrated a BP-lowering effect and improved albuminuria. The effects were consistent regardless of the severity of albuminuria without clinically relevant serum potassium elevation and eGFR reduction. CLINICAL TRIAL REGISTRATION jRCTs06119002.

Abstract
BACKGROUND The prevalence of diabetes mellitus has been increased dramatically which in turn leads to complications including cardiovascular diseases, diabetic kidney disease, and substantially end-stage renal disease. METHODS We reviewed articles discussing the pathophysiology of diabetic nephropathy with new agents that may be useful in the management of the disease. We used PubMed, Scopus, Google Scholar and the Open-access searching engines. RESULTS The recent recommendations primarily depend on glycaemic and blood pressure control and the use of standard renin-angiotensin system blockade. Currently, the use of agents with nephroprotective effects beyond the hyperglycaemic lowering effect has been evidenced clinically. CONCLUSIONS In his review, the pathophysiology, clinical manifestations, and lines of treatment of diabetic nephropathy are discussed. In addition, a focus on the clinical role and nephroprotective effects of the emerging therapeutic class, dipeptidyl peptidase IV (DPP-4) inhibitors, is addressed in detail.

Abstract
Aldosterone sensitivity is defined as an outcome variable for a given circulating level of aldosterone. In basic and translational studies, aldosterone sensitivity has been measured in differential tissue responses, e.g., lower urine sodium and higher urine potassium, as an index of the renal response; in clinical studies, aldosterone sensitivity has been measured in differential blood pressure responses. The concept of aldosterone sensitivity disrupts the conventional wisdom of the renin-angiotensin-aldosterone system and has the potential to uncover novel mechanisms of hypertension. Here, we review basic and translational science studies that uncovered differential renal responses to aldosterone and connect this earlier work to more recent observational studies and randomized trials that have demonstrated differential blood pressure responses for a given level of aldosterone in healthy and hypertensive persons. Black race and older age are associated with higher aldosterone sensitivity and blood pressure. We also discuss gaps in the field and how future basic and clinical studies might inform mechanisms of differential sensitivity.

Impact of mineralocorticoid receptor blockade with direct renin inhibition in angiotensin II-dependent hypertensive mice. Hypertens Res 2020; 43:1099-1104.

Abstract
It has been suggested that aldosterone breakthrough during treatment with a type 1 angiotensin II receptor (AT1R) blocker (ARB) may be an important risk factor for the progression of renal and cardiovascular disease. We examined whether the direct renin inhibitor, aliskiren caused aldosterone breakthrough in angiotensin II (Ang II)-dependent hypertensive mice. The effect of combination therapy with aliskiren and eplerenone was compared with that of therapy using renin-angiotensin system (RAS) blockade. Tsukuba hypertensive mice were treated for 12 weeks with aliskiren (30 mg/kg/day, i.p), candesartan (5 mg/kg/day, p.o), eplerenone (100 mg/kg/day, p.o) aliskiren and candesartan, aliskiren and eplerenone or candesartan and eplerenone. Blood pressure, urinary aldosterone and angiotensinogen (AGTN) excretion; plasma endothelin-1 concentration; kidney weight; urinary albumin excretion (UAE); glomerular injury; and renal messenger RNA (mRNA) levels for transforming growth factor (TGF)-β1, plasminogen activator inhibitor (PAI)-1, angiotensin-converting enzyme (ACE) and AT1R were measured. Combination therapy with aliskiren and candesartan caused a further decrease in blood pressure (p < 0.05) compared with either agent alone. Urinary aldosterone excretion was decreased significantly by 4 weeks of treatment with aliskiren or candesartan (p < 0.05). However, it was increased again by treatment with candesartan or aliskiren for 12 weeks. Combination therapy with aliskiren and eplerenone significantly decreased UAE, the glomerulosclerosis index, and PAI-1 and TGF-β1 mRNA levels compared with all other therapies (p < 0.05). Treatment with aliskiren decreased urinary aldosterone excretion at 4 weeks and increased it at 12 weeks. Combination therapy with a direct renin inhibitor and a mineralocorticoid receptor blocker may be effective for the prevention of renal injury in Ang II-dependent hypertension.

Abstract
PURPOSE OF REVIEW Recently, nonsteroidal mineralocorticoid receptor (MR) antagonists (MRAs), which have been proposed to be called MR blockers (MRBs), have become available for clinical use, but their clinical role is unknown. We reviewed the clinical roles of MRAs and MRBs based on previous knowledge and as demonstrated in representative clinical trials. RECENT FINDINGS Steroidal MRAs, such as spironolactone and eplerenone, inhibit the action of aldosterone and cortisol in MRs expressed in several organs and cell types, and accumulating clinical studies have revealed that they exert hypotensive and cardiorenal protective effects. Recently, MRBs, including finerenone and esaxerenone, have been developed and are expected to lower the risk of hyperkalemia, which is common when steroidal MRAs are used. Although the differences between MRAs and MRBs in clinical practice have not yet been established, further studies in this field are expected to broaden our understanding. MRBs exert antihypertensive and cardiorenal protective effects, and their potency is thought to be far superior to that of MRAs, because MRBs have both strong MR inhibitory action and high selectivity. Thus, MRBs could be a promising agent for the treatment of hypertension and cardiorenal, cerebral, and metabolic disorders.

Abstract
OBJECTIVES This study was conducted to evaluate the effect of eplerenone on the RAAS and kidney function in rats with thyroid hormone disorders. METHODS This study involved 30 male Wistar albino rats, divided into three groups. The first group (N = 6) served as a control. The second group involved 12 rats with experimentally induced hypothyroidism through receiving propylthiouracil (0.05% w/v) in drinking water for one month, which was divided into two subgroups of six rats each. The first subgroup served as a positive hypothyroid control, and the second subgroup received oral daily dose of eplerenone (100 mg/kg) for 14 days. The third group included 12 rats with induced hyperthyroidism with L-thyroxin (0.0012% w/v) in drinking water, and rats in this group were also divided into two subgroups. The first subgroup served as a positive hyperthyroid control, and the second subgroup received oral eplerenone 100 mg/kg. RESULTS Eplerenone indicated a significant increase in renin and angiotensin I from 184.09 pg/ml and 178.66 pg/ml to 603.31 pg/ml and 250.88 pg/ml, respectively, meanwhile, aldosterone indicated no significant changes after inducing hypothyroidism and eplerenone administration. The induction of hyperthyroidism led to a significant increase in angiotensin I from 248.84 pg/ml to 292.22 pg/ml. Oral administration of eplerenone for 14 days caused a significant increase aldosterone from 364.23 pg/ml to 497.02 pg/ml. CONCLUSION Eplerenone significantly increased the serum renin and angiotensin I in hypothyroid and aldosterone and angiotensin I in hyperthyroid rats. Aldosterone in hypothyroid rats was not changed by eplerenone.

Abstract
OBJECTIVES Although mineralocorticoid antagonists (MRAs) have been proposed as effective fourth-line blood pressure (BP)-lowering agents in resistant hypertension, this effect in hypertension at-large is unclear. We evaluated whether MRAs-mediated BP lowering is both effective and safe against controls and whether the extent of BP lowering differs between resistant hypertension and nonresistant hypertension . METHODS We searched Medline and the Cochrane Collaboration Library databases from 1991 to mid-September 2017 for randomized controlled trials (RCTs), in which MRAs were compared with placebo or other active drugs. Main outcomes were SBP and DBP lowering and treatment-related discontinuations. Continuous outcome variables were pooled as mean difference and the categorical variables as risk ratios, both with 95% confidence interval (CI). The risk of bias was assessed by using the Cochrane collaboration tool. RESULTS We included 21 RCTs (2736 patients) of MRAs compared either with placebo or with active agents. Whenever all selected trials were analyzed together (MRAs versus controls), the resulting BP reduction was -7.6 (95% CI -10 to -5.3) mmHg for SBP and -2.5 (95% CI -4.2 to -0.8) mmHg for DBP, while limiting our analysis to MRAs versus placebo mean difference was increased by -2.1/-1.3 mmHg. We find no differential BP lowering between resistant hypertension and non-resistant hypertension. Treatment-related discontinuations were not different compared with either placebo or active comparators. CONCLUSION As the extent of BP lowering following treatment with MRAs in patients with and without resistant hypertension was similar and not accompanied by increased rate of treatment-related discontinuations compared with other active comparators, these agents may have a role in BP lowering in already treated hypertensive patients who did not reach target BP values.

Abstract
Purpose Several options are available for the treatment of hypertension; however, many treated patients are still not below blood pressure (BP) target. Eplerenone, a selective mineralocorticoid receptor antagonist, is an approved treatment option for the management of patients with hypertension in a number of countries. This patient-level pooled analysis was conducted to document the efficacy and safety/tolerability of eplerenone at the dosages approved for use in hypertension in comparison to placebo or other approved antihypertensive agents. Methods Seventeen Phase III studies conducted in patients with mild-to-moderate hypertension in the Eplerenone Hypertension Clinical Program were reviewed; eleven met the selection criteria. The primary endpoint was change from baseline in seated diastolic BP and seated systolic BP measured at the end of the study. Results A total of 2,698 patients were included in this per-protocol analysis. In patients treated for at least 6 weeks with a stable dose of eplerenone, doses of 50 mg daily and 100 mg daily were associated with greater reductions of seated systolic BP and seated diastolic BP compared with placebo (P<0.001) and active-controlled studies (P< 0.033). In the analysis of covariance model testing of the contribution of four factors (age, body mass index [BMI], history of cardiovascular disease, and diabetes) on the BP lowering effects of eplerenone, only BMI and age were associated with small though statistically significant changes in BP (<0.2 mmHg). Eplerenone was well tolerated; headache was the most common adverse event for patients in any group. Severe hyperkalemia (serum potassium level >6.0 mmol/L) occurred in up to 0.4% in the eplerenone groups, 0.4% in the placebo group, and 0.1% in the active-control group. Conclusion This patient-level pooled analysis provides robust evidence that eplerenone, at 50 mg or 100 mg daily, was effective in lowering BP in patients with mild-to-moderate hypertension and was well tolerated.

Abstract
PURPOSE OF REVIEW Emerging evidence suggests that multiple mechanisms may be responsible for the development of treatment-resistant hypertension (TRH). This review aims to summarize recent data on potential mechanisms of resistance and discuss current pharmacotherapeutic options available in the management of TRH. RECENT FINDINGS Excess sodium and fluid retention, increased activation of the renin-angiotensin-aldosterone system, and heightened activity of the sympathetic nervous system appear to play an important role in development of TRH. Emerging evidence also suggests a role for arterial stiffness and, potentially, gut dysbiosis. Therapeutic approaches for TRH should include diuretic optimization and the addition of aldosterone antagonists as the preferred fourth agent in most patients. Further therapeutic approaches may be guided by the suspected underlying mechanism of TRH in conjunction with other patient-specific factors. The pathophysiology of TRH is multifaceted; however, increasing evidence supports several mechanisms that may be targeted to improve blood pressure control among patients with TRH. Further studies are needed to determine whether such approaches may be more effective than usual care.

Abstract
BACKGROUND Primary aldosteronism is recognized as a severe form of renin-independent aldosteronism that results in excessive mineralocorticoid receptor (MR) activation. OBJECTIVE To investigate whether a spectrum of subclinical renin-independent aldosteronism that increases risk for hypertension exists among normotensive persons. DESIGN Cohort study. SETTING National community-based study. PARTICIPANTS 850 untreated normotensive participants in MESA (Multi-Ethnic Study of Atherosclerosis) with measurements of serum aldosterone and plasma renin activity (PRA). MEASUREMENTS Longitudinal analyses investigated whether aldosterone concentrations, in the context of physiologic PRA phenotypes (suppressed, ≤0.50 µg/L per hour; indeterminate, 0.51 to 0.99 µg/L per hour; unsuppressed, ≥1.0 µg/L per hour), were associated with incident hypertension (defined as systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or initiation of antihypertensive medications). Cross-sectional analyses investigated associations between aldosterone and MR activity, assessed via serum potassium and urinary fractional excretion of potassium. RESULTS A suppressed renin phenotype was associated with a higher rate of incident hypertension than other PRA phenotypes (incidence rates per 1000 person-years of follow-up: suppressed renin phenotype, 85.4 events [95% CI, 73.4 to 99.3 events]; indeterminate renin phenotype, 53.3 events [CI, 42.8 to 66.4 events]; unsuppressed renin phenotype, 54.5 events [CI, 41.8 to 71.0 events]). With renin suppression, higher aldosterone concentrations were independently associated with an increased risk for incident hypertension, whereas no association between aldosterone and hypertension was seen when renin was not suppressed. Higher aldosterone concentrations were associated with lower serum potassium and higher urinary excretion of potassium, but only when renin was suppressed. LIMITATION Sodium and potassium were measured several years before renin and aldosterone. CONCLUSION Suppression of renin and higher aldosterone concentrations in the context of this renin suppression are associated with an increased risk for hypertension and possibly also with increased MR activity. These findings suggest a clinically relevant spectrum of subclinical primary aldosteronism (renin-independent aldosteronism) in normotension. PRIMARY FUNDING SOURCE National Institutes of Health.

Abstract
CONTEXT Mild cases of autonomous aldosterone secretion may go unrecognized using current diagnostic criteria for primary aldosteronism (PA). OBJECTIVE To investigate whether the inability to stimulate renin serves as a biomarker for unrecognized autonomous aldosterone secretion and mineralocorticoid receptor (MR) activation. PARTICIPANTS Six hundred sixty-three normotensive and mildly hypertensive participants, who were confirmed to not have PA using current guideline criteria and were on no antihypertensive medications. DESIGN Participants had their maximally stimulated plasma renin activity (PRA) measured while standing upright after sodium restriction. Tertiles of maximally stimulated PRA were hypothesized to reflect the degree of MR activation: lowest PRA tertile = "Inappropriate/Excess MR Activity;" middle PRA tertile = "Intermediate MR Activity;"; and highest PRA tertile = "Physiologic MR Activity." All participants underwent detailed biochemical and vascular characterizations under conditions of liberalized sodium intake, and associations with stimulated PRA phenotypes were performed. RESULTS Participants with lower stimulated PRA had greater autonomous aldosterone secretion [higher aldosterone-to-renin ratio (P = 0.002), higher urine aldosterone excretion rate (P = 0.003), higher systolic blood pressure (P = 0.004), and lower renal plasma flow (P = 0.04)] and a nonsignificant trend toward lower serum potassium and higher urine potassium excretion, which became significant after stratification by hypertension status. CONCLUSIONS In participants without clinical PA, the inability to stimulate renin was associated with greater autonomous aldosterone secretion, impaired vascular function, and suggestive trends in potassium handling that indicate an extensive spectrum of unrecognized MR activation.

Abstract
The renin-angiotensin-aldosterone system (RAAS) plays a fundamental role in the physiology of blood pressure control and the pathophysiology of hypertension (HTN) with effects on vascular tone, sodium retention, oxidative stress, fibrosis, sympathetic tone, and inflammation. Fortunately, RAAS blocking agents have been available to treat HTN since the 1970s and newer medications are being developed. In this review, we will (1) examine new anti-hypertensive medications affecting the RAAS, (2) evaluate recent studies that help provide a better understanding of which patients may be more likely to benefit from RAAS blockade, and (3) review three recent pivotal randomized trials that involve newer RAAS blocking agents and inform clinical practice.

Abstract
Spironolactone and eplerenone are both mineralocorticoid-receptor antagonists. These compounds block both the epithelial and nonepithelial actions of aldosterone, with the latter assuming increasing clinical relevance. Spironolactone and eplerenone both affect reductions in blood pressure either as mono- or add-on therapy; moreover, they each afford survival benefits in diverse circumstances of heart failure and the probability of renal protection in proteinuric chronic kidney disease. However, as use of mineralocorticoid-blocking agents has expanded, the hazards inherent in taking such drugs have become more apparent. Whereas the endocrine side effects of spironolactone are in most cases little more than a cosmetic annoyance, the potassium-sparing effects of both spironolactone and eplerenone can prove disastrous, even fatal, if sufficient degrees of hyperkalemia emerge. For most patients, however, the risk of developing hyperkalemia in and of itself should not discourage the sensible clinician from bringing these compounds into play. Hyperkalemia should always be considered a possibility in patients receiving either of these medications; therefore, anticipatory steps should be taken to minimize the likelihood of its occurrence if long-term therapy of these agents is being considered.

Abstract
Pathway-2 is the first randomised, double-blind and crossover trial that compares spironolactone as a fourth drug with alfa-blocker, beta-blocker and placebo. This study shows that spironolactone is the drug with more possibilities of success for the management of patients with difficult-to-treat hypertension in patients with a combination of three drugs and poor control. The results validate the widespread treatment with mineralocorticoid receptor antagonists in resistant hypertension.

Abstract
INTRODUCTION Cardiovascular disease (CVD) is the leading cause of death worldwide. Blockade of this system is commonly used in the treatment of cardiovascular (CV) and renal disease. AREAS COVERED Data from multiple clinical trials have provided good evidence about the benefit of blocking the system as a therapeutic target to reduce CV and renal events. We have reviewed all the tested combinations of different drugs counteracting the effects of the renin-angiotensin-aldosterone system. EXPERT OPINION Monotherapy with an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin II receptor blocker (ARB) remains valid in all the guidelines, whereas their dual combination has been discarded due to the absence of proven benefits in high CV risk patients and in patients with chronic kidney disease (CKD). The combination of the standard therapy with an ACEi or an ARB with a mineralocorticoid receptor blocker is a valid option, but has the inconvenience of frequent hyperkalemia in patients with CKD. Similarly, the addition of the direct renin inhibitor, aliskiren, to this standard therapy is not particularly supported in diabetic patients. New dual-acting blockers, for example, those combining valsartan and neprilysin inhibitors (LCZ696-Novartis) or endothelin converting enzyme inhibitors and neprilysin inhibitors (ECEI, Daglutril-Solvay), are currently under investigation.

Abstract
Despite the availability of anti-hypertensive medications with increasing efficacy up to 50% of hypertensive patients have blood pressure levels (BP) not at the goals set by international societies. Some of these patients are either not optimally treated or are non-adherent to the prescribed drugs. However, a proportion, despite adequate treatment, have resistant hypertension (RH), which represents an important problem in that it is associated to an excess risk of cardiovascular events. Notwithstanding a complex pathogenesis, an abundance of data suggests a key contribution for the mineralocorticoid receptor (MR) in RH, thus fostering a potential role for its antagonists in RH. Based on these premises randomized clinical trials aimed at testing the efficacy of MR antagonists (MRAs) in RH patients have been completed. Overall, they demonstrated the efficacy of MRAs in reducing BP and surrogate markers of target organ damage, such as microalbuminuria, either compared to placebo or to other drugs. In summary, owing to the key role of the MR in the pathogenesis of RH and on the proven efficacy of MRAs we advocate their inclusion as an essential component of therapy in patients with presumed RH. Conversely, we propose that RH should be diagnosed only in patients whose BP values show to be resistant to an up-titrated dose of these drugs.

Abstract
The mineralocorticoid receptor antagonists have been shown to have favourable safety and cost-effectiveness profiles across a broad range of clinical indications, including heart failure, primary aldosteronism and resistant hypertension. The clinical biology of the first aldosterone blocker, i.e. spironolactone, and its effects in several organ systems has been well elucidated from multiple studies. The range of adverse effects experienced with spironolactone has led to its modification and the consequent synthesis of eplerenone. Scientific evidence accumulated so far supports the role of eplerenone as first-choice drug in heart failure, with lower prevalence rates of sex-related adverse effects associated with eplerenone as compared to spironolactone. In Europe, eplerenone is currently marketed only in some countries and only with the indication of heart failure, whereas its clinical efficacy and safety in mild to moderate hypertension is said to be uncertain. A review of available scientific evidence, however, discloses that 11 randomized clinical trials assessing eplerenone in >3500 hypertensives have been reported so far. The results of these studies clearly show that eplerenone is an effective antihypertensive agent when used alone or in combination with other medications. In doses ranging from 25 to 100mg daily, eplerenone monotherapy results in a dose-dependent reduction in clinic blood pressure. As compared to placebo, eplerenone reduces significantly blood pressure from baseline. In general, 100mg daily eplerenone has a blood pressure lowering that is 50 to 75% that of spironolactone. Eplerenone results in a greater reduction in blood pressure as compared with losartan, and comparison between eplerenone and amlodipine shows that both treatments decrease systolic blood pressure to a similar extent but eplerenone is better tolerated. In conclusion, there is now evidence that eplerenone can play an important role in the treatment of mild to moderate arterial hypertension and therefore scientific experts and regulatory authorities should support its wider use in clinical practice worldwide.

Abstract
The epidemiology, evaluation, and management of severe and resistant hypertension in the United States (US) are evolving. The American Society of Hypertension held a multi-disciplinary forum in October 2013 to review the available evidence related to the management of resistant hypertension with both drug and device therapies. There is strong evidence that resistant hypertension is an important clinical problem in the US and many other regions of the world. Complex drug therapy is effective in most of the patients with severe and resistant hypertension, but there are certain individuals who may be refractory to multiple-drug regimens or have adverse effects that make adherence to the regimen difficult. When secondary forms of hypertension and pseudo-resistance, such as medication nonadherence, or white-coat hypertension based on marked differences between clinic and 24-hour ambulatory blood pressure monitoring, have been excluded, the impact of device therapy is under evaluation through clinical trials in the US and from clinical practice registries in Europe and Australia. Clinical trial data have been obtained primarily in patients whose resistant hypertension is defined as systolic clinic blood pressures of ≥160 mm Hg (or ≥ 150 mm Hg in type 2 diabetes) despite pharmacologic treatment with at least three antihypertensive drugs (one of which is a thiazide or loop diuretic). Baroreceptor stimulation therapy has shown modest benefit in a moderately sized sham-controlled study in drug-resistant hypertension. Patients selected for renal denervation have typically been restricted to those with preserved kidney function (estimated glomerular filtration rate ≥ 45 mL/min/1.73 m2). The first sham-controlled safety and efficacy trial for renal denervation (SYMPLICITY HTN-3) did not show benefit in this population when used in addition to an average of five antihypertensive medications. Analyses of controlled clinical trial data from future trials with novel designs will be of critical importance to determine the effectiveness of device therapy for patients with severe and resistant hypertension and will allow for proper determination of patient selection and whether it will be acceptable for clinical practice. At present, the focus on the management of severe and resistant hypertension will be through careful evaluation for pseudo-resistance and secondary forms of hypertension, appropriate use of combination pharmacologic therapy, and greater utility of specialists in hypertension.

Genetic variation in CYP4A11 and blood pressure response to mineralocorticoid receptor antagonism or ENaC inhibition: an exploratory pilot study in African Americans. JOURNAL OF THE AMERICAN SOCIETY OF HYPERTENSION : JASH 2014; 8:475-80. [PMID: 25064769 PMCID: PMC4115247 DOI: 10.1016/j.jash.2014.04.011] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2014] [Revised: 04/30/2014] [Accepted: 04/30/2014] [Indexed: 11/23/2022]
Abstract
An rs3890011 variant of CYP4A11, which is in linkage disequilibrium with the loss-of-function variant rs1126742, is associated with hypertension in humans. In mice, Cyp4a deficiency results in salt-sensitive hypertension through activation of ENaC. We tested the hypothesis that the rs3890011 variant is associated with blood pressure response to drugs acting via the ENaC pathway. African Americans with volume-dependent, resistant hypertension were randomized to treatment with placebo, spironolactone, amiloride, or combination. Blood pressure responses were analyzed by CYP4A11 genotypes. Rs3890011 (GG:GC:CC = 20:35:28) and rs1126742 (TT:TC:CC = 45:31:7) were in linkage disequilibrium (D' = 1, r = 0.561). Expected small number of rs1126742 CC homozygotes precluded analysis of the effect of this genotype on treatment responses. Spironolactone reduced blood pressure in rs3890011 GG and GC individuals, but not in CC homozygotes (P = .002), whereas amiloride reduced blood pressure similarly in all rs3890011 genotypes. The antihypertensive effects of spironolactone and amiloride were comparable in GG and GC participants, but only amiloride reduced pressure in CC homozygotes (-6.3 ± 7.3/-3.2 ± 4.0 vs. +6.8 ± 7.9/+4.8 ± 8.6 mm Hg, P < .01/<.05). The aldosterone response to spironolactone was also blunted in the CC genotype. In individuals homozygous for the CYP4A11 rs3890011 C allele, blood pressure is resistant to mineralocorticoid receptor antagonism, but sensitive to ENaC inhibition, consistent with ENaC activation. Studies in a larger population are needed to replicate these findings.

Abstract
Hypertension is the most important cardiovascular risk factor. We have witnessed a significant improvement in hypertension treatment and control and an impressive growth in the pharmacologic options available to clinicians and hypertension specialists. With up to a third of patients with hypertension not at the recommended goal blood pressures, it is critically important to develop novel therapeutic approaches to better treat hypertension. This review will explore the ever-expanding horizon of antihypertensive treatment and will focus on 2 major areas of drug development. First, we will review novel targets for pharmacologic treatment and novel molecules and classes of drugs in various phases of development and recognize the limitations we face in their transition from research and development to clinical practice. Then, we will discuss an expanding array of combination strategies to better treat hypertension with the goal of minimizing the burden of cardiovascular and renal complications of hypertension.

Abstract
Primary aldosteronism (PA) is the most common etiology of endocrine hypertension (HTN), and recent prevalence studies suggest that it may be under-diagnosed. Indications for screening have been expanded with recognition that many patients with PA do not have hypokalemia and that the disease may be familial. The aldosterone:renin ratio (ARR) is the preferred screening test for PA. The ARR can be interpreted in patients on most anti-hypertensive agents, and can be used to guide medical therapy of HTN even in patients without PA. Once PA is confirmed, adrenal venous sampling (AVS) should be performed to determine if PA is due to bilateral disease or a unilateral adenoma, if surgery is being considered. Targeted medical or surgical therapy improves patient outcomes.

Abstract
Mineralocorticoid receptor antagonists (MRAs) are commonly used to reduce blood pressure, left-ventricular hypertrophy, and urinary albumin excretion in patients with essential hypertension or primary aldosteronism. Effects of MRAs on hypertensive organ damage seem to occur beyond what is expected from the mere reduction of blood pressure. This suggests that activation of the mineralocorticoid receptor plays a central role in the development of cardiac and renal abnormalities in hypertensive patients. However, broad use of classic MRAs such as spironolactone has been limited by significant incidence of gynecomastia and other sex-related adverse effects. To overcome these problems, new aldosterone blockers have been developed with different strategies that include use of nonsteroidal MRAs and inhibition of aldosterone synthesis. Both strategies have been designed to avoid the steroid receptor cross-reactivity of classic MRAs that accounts for most adverse effects. Moreover, inhibition of aldosterone synthesis could have an additional benefit due to blockade of the mineralocorticoid receptor-independent pathways that might account for some of the untoward effects of aldosterone. The new aldosterone blockers are currently having extensive preclinical evaluation, and one of these compounds has passed phase 2 trials showing promising results in patients with primary hypertension and primary aldosteronism. This narrative review summarizes the knowledge on the use of classic MRAs in hypertension and covers the evidence currently available on new aldosterone blockers.

Abstract
BACKGROUND Add-on therapy with aldosterone receptor antagonists has been reported to lower blood pressure (BP) in patients with uncontrolled hypertension. We assessed potential predictors of this response. METHODS In essential hypertensive patients with uncontrolled BP, despite the use of at least two antihypertensives, plasma renin and aldosterone concentrations and the transtubular potassium gradient (TTKG) were measured. Patients were treated with eplerenone 50 mg daily on top of their own medication. The office and ambulatory BP response and biochemical changes were evaluated after 1 week and 3 months of treatment and 6 weeks after discontinuation. Potential predictors for the change in 24-h ambulatory BP were tested in a multivariate regression model. RESULTS One hundred and seventeen patients with a mean age of 50.5 ± 6.6 years were included. Office BP decreased from 149/91 to 142/87 mmHg (P < 0.001) and ambulatory BP from 141/87 to 132/83 mmHg after 3 months of treatment (P < 0.001). Six weeks after discontinuation of eplerenone, office and ambulatory BP measurements returned to baseline values. Treatment resulted in a small rise in serum potassium and creatinine, and a small decrease in the TTKG. In a multivariate model, neither renin, aldosterone, or their ratio, nor the TTKG predicted the BP response. Only baseline ambulatory SBP predicted the BP response, whereas the presence of left ventricular hypertrophy was associated with a smaller BP reduction. CONCLUSION Add-on therapy with eplerenone effectively lowers BP in patients with difficult-to-treat primary hypertension. This effect is unrelated to circulating renin-angiotensin-aldosterone system activity and renal mineralocorticoid receptor activity as assessed by the TTKG.

Upregulation of the Renin-Angiotensin-aldosterone-ouabain system in the brain is the core mechanism in the genesis of all types of hypertension. Int J Hypertens 2012; 2012:242786.

Abstract
Basic research using animal models points to a causal role of the central nervous system in essential hypertension; however, since clinical research is technically difficult to perform, this connection has not been confirmed in humans. Recently, renal nerve ablation in humans proved to continuously decrease blood pressure in resistant hypertension. Furthermore, when electrical stimulation was continuously applied to the carotid baroreceptor nerve of human adults, their blood pressure lowered. These findings promoted the concept that the central nervous system may actually be involved in the pathogenesis of essential hypertension, which is closely associated with excess sodium intake. We have demonstrated that endogenous digitalis plays a key role in hypertension associated with excess sodium intake via sympathetic activation in rats. Increased sodium concentration inside the brain activates epithelial sodium channels and the renin-angiotensin-aldosterone system in the brain. Aldosterone releases ouabain from neurons in the paraventricular nucleus in the hypothalamus. Angiotensin II and aldosterone of peripheral origin reach the brain to augment sympathetic outflow. Collectively essential hypertension associated with excess sodium intake and obesity, renovascular hypertension, and primary aldosteronism and pseudoaldosteronism all seem to have a common cause originating from the central nervous system.

Abstract
Although various effective treatments for hypertension are available, novel therapies to reduce elevated blood pressure, improve blood-pressure control, treat resistant hypertension, and reduce the associated cardiovascular risk factors are still required. A novel angiotensin-receptor blocker (ARB) was approved in 2011, and additional compounds are in development or being tested in clinical trials. Several of these agents have innovative mechanisms of action (an aldosterone synthase inhibitor, a natriuretic peptide agonist, a soluble epoxide hydrolase inhibitor, and an angiotensin II type 2 receptor agonist) or dual activity (a combined ARB and neutral endopeptidase inhibitor, an ARB and endothelin receptor A blocker, and an endothelin-converting enzyme and neutral endopeptidase inhibitor). In addition, several novel fixed-dose combinations of existing antihypertensive agents were approved in 2010-2011, including aliskiren double and triple combinations, and an olmesartan triple combination. Upcoming fixed-dose combinations are expected to introduce calcium-channel blockers other than amlodipine and diuretics other than hydrochlorothiazide. Finally, device-based approaches to the treatment of resistant hypertension, such as renal denervation and baroreceptor activation therapy, have shown promising results in clinical trials. However, technical improvements in the implantation procedure and devices used for baroreceptor activation therapy are required to address procedural safety concerns.

Abstract
Resistant hypertension has evolved as an important global health care problem. Primary aldosteronism is one of several potentially reversible causes of resistant hypertension. Primary aldosteronism can be effectively treated, when recognized, with a mineralocorticoid receptor antagonist, such as spironolactone and eplerenone. Each of these compounds can reduce blood pressure as monotherapy or when given with a range of other antihypertensive drug classes. These compounds have distinctive pharmacokinetic and pharmacodynamic patterns that require some forethought in their use before they are prescribed. However, as the use of mineralocorticoid-blocking agents has gradually increased, the hazards inherent to use of such drugs has become more apparent. Whereas the endocrine side effects of spironolactone are in most cases little more than a cosmetic annoyance, the potassium-sparing effects of both spironolactone and eplerenone can prove fatal if sufficient degrees of hyperkalemia develop. However, for most patients the risk of developing hyperkalemia in and of itself should not discourage the prudent clinician from bringing these compounds into play. Hyperkalemia should always be considered as a likelihood in any patient receiving one or the other of these medications. As such, steps should be taken to lessen the likelihood of it occurring if therapy is being contemplated with agents in this class.

Abstract
The central nervous system has a key role in regulating the circulatory system by modulating the sympathetic and parasympathetic nervous systems, pituitary hormone release, and the baroreceptor reflex. Digoxin- and ouabain-like immunoreactive materials were found >20 years ago in the hypothalamic nuclei. These factors appeared to localize to the paraventricular and supraoptic nuclei and the nerve fibers at the circumventricular organs and supposed to affect electrolyte balance and blood pressure. The turnover rate of these materials increases with increasing sodium intake. As intracerebroventricular injection of ouabain increases blood pressure via sympathetic activation, an endogenous digitalis-like factor (EDLF) was thought to regulate cardiovascular system-related functions in the brain, particularly after sodium loading. Experiments conducted mainly in rats revealed that the mechanism of action of ouabain in the brain involves sodium ions, epithelial sodium channels (ENaCs) and the renin-angiotensin-aldosterone system (RAAS), all of which are affected by sodium loading. Rats fed a high-sodium diet develop elevated sodium levels in their cerebrospinal fluid, which activates ENaCs. Activated ENaCs and/or increased intracellular sodium in neurons activate the RAAS; this releases EDLF in the brain, activating the sympathetic nervous system. The RAAS promotes oxidative stress in the brain, further activating the RAAS and augmenting sympathetic outflow. Angiotensin II and aldosterone of peripheral origin act in the brain to activate this cascade, increasing sympathetic outflow and leading to hypertension. Thus, the brain Na(+)-ENaC-RAAS-EDLF axis activates sympathetic outflow and has a crucial role in essential and secondary hypertension. This report provides an overview of the central mechanism underlying hypertension and discusses the use of antihypertensive agents.

Abstract
The conventional antihypertensive therapies including renin–angiotensin–aldosterone system antagonists (converting enzyme inhibitors, receptor blockers, renin inhibitors, and mineralocorticoid receptor blockers), diuretics, β-blockers, and calcium channel blockers are variably successful in achieving the challenging target blood pressure values in hypertensive patients. Difficult to treat hypertension is still a commonly observed problem world-wide. A number of drugs are considered to be used as novel therapies for hypertension. Renalase supplementation, vasopeptidase inhibitors, endothelin antagonists, and especially aldosterone antagonists (aldosterone synthase inhibitors and novel selective mineralocorticoid receptor blockers) are considered an option in resistant hypertension. In addition, the aldosterone antagonists as well as (pro)renin receptor blockers or AT2 receptor agonists might attenuate end-organ damage. This array of medications has now been complemented by a number of new approaches of non-pharmacological strategies including vaccination, genomic interference, controlled breathing, baroreflex activation, and probably most successfully renal denervation techniques. However, the progress on innovative therapies seems to be slow and the problem of resistant hypertension and proper blood pressure control appears to be still persisting. Therefore the regimens of currently available drugs are being fine-tuned, resulting in the establishment of several novel fixed-dose combinations including triple combinations with the aim to facilitate proper blood pressure control. It remains an exciting question which approach will confer the best blood pressure control and risk reduction in this tricky disease.

Abstract
The renin-angiotensin-aldosterone system (RAAS) is inappropriately activated in obesity. In individuals at risk for diabetes, RAAS inhibition protects against kidney and heart disease, and also reduces the incidence of diabetes in large clinical trials. At a cellular level, angiotensin II (Ang II) and aldosterone induce insulin resistance by increasing oxidative stress and altering insulin signaling, leading to decreased glucose transport. Ang II also contributes to oxidative stress, inflammation, and apoptosis in pancreatic β cells. Aldosterone diminishes glucose-stimulated insulin secretion in vivo and in vitro from isolated pancreatic islets and cultured β cells through a mineralocorticoid receptor (MR)-independent mechanism. We review these findings in the context of pharmacological strategies interrupting the RAAS to highlight the potential application of these strategies to the prevention of diabetes progression.

Abstract
Hypertension is difficult to treat in patients with type 2 diabetes mellitus (T2DM) or obesity. Combination therapies are often required to effectively lower blood pressure (BP) and attain BP goals. In this post-hoc analysis of 2 prospective, randomized, controlled studies in patients with uncontrolled or untreated moderate or severe hypertension, the efficacy and safety of treatment with irbesartan/hydrochlorothiazide (HCTZ) and irbesartan was assessed in 2 separate analyses: patients with diabetes (n=143) and by obesity status (n=1125). Patients received irbesartan/HCTZ (150 mg/12.5 mg titrated to 300 mg/25 mg) or irbesartan (150 mg titrated to 300 mg) for 7 (severe hypertension study) or 12 (moderate hypertension study) weeks. Efficacy comparisons between treatment groups were performed using Fisher's exact tests. After 7 to 8 weeks of treatment, systolic BP (SBP)/diastolic BP (DBP) decreased in patients with diabetes by 26.9/17.8 mm Hg and 21.8/15.8 mm Hg after irbesartan/HCTZ and irbesartan treatment, respectively (P [SBP]=0.09, P [DBP]=0.27). In obese patients (n=544), SBP/DBP decreased by 29.4/20.2 mm Hg and 20.1/15.9 mm Hg after irbesartan/HCTZ and irbesartan treatment, respectively (P<0.0001). More patients with T2DM reached the BP goal of <130/80 mm Hg at week 7 to 8 in the irbesartan/HCTZ group than in the irbesartan group (12% vs 5%), although not statistically significant (P=0.22). Significantly more obese patients reached their respective BP goals in the irbesartan/HCTZ group than in the irbesartan group (48% vs 23%; P<0.0001). Treatment-emergent adverse event rates were similar between treatment groups regardless of the presence of diabetes or body mass index (BMI) status. In patients with moderate or severe hypertension and with a BMI ≥ 30 kg/m(2), initial treatment with irbesartan/HCTZ combination therapy was more effective than irbesartan monotherapy.

Aldosterone decreases glucose-stimulated insulin secretion in vivo in mice and in murine islets. Diabetologia 2011; 54:2152-63. [PMID: 21519965 PMCID: PMC3216479 DOI: 10.1007/s00125-011-2158-9] [Citation(s) in RCA: 80] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2011] [Accepted: 03/28/2011] [Indexed: 12/26/2022]
Abstract
AIMS/HYPOTHESIS Aldosterone concentrations increase in obesity and predict the onset of diabetes. We investigated the effects of aldosterone on glucose homeostasis and insulin secretion in vivo and in vitro. METHODS We assessed insulin sensitivity and insulin secretion in aldosterone synthase-deficient (As [also known as Cyp11b2](-/-)) and wild-type mice using euglycaemic-hyperinsulinaemic and hyperglycaemic clamps, respectively. We also conducted studies during high sodium intake to normalise renin activity and potassium concentration in As (-/-) mice. We subsequently assessed the effect of aldosterone on insulin secretion in vitro in the presence or absence of mineralocorticoid receptor antagonists in isolated C57BL/6J islets and in the MIN6 beta cell line. RESULTS Fasting glucose concentrations were reduced in As (-/-) mice compared with wild-type. During hyperglycaemic clamps, insulin and C-peptide concentrations increased to a greater extent in As (-/-) than in wild-type mice. This was not attributable to differences in potassium or angiotensin II, as glucose-stimulated insulin secretion was enhanced in As (-/-) mice even during high sodium intake. There was no difference in insulin sensitivity between As (-/-) and wild-type mice in euglycaemic-hyperinsulinaemic clamp studies. In islet and MIN6 beta cell studies, aldosterone inhibited glucose- and isobutylmethylxanthine-stimulated insulin secretion, an effect that was not blocked by mineralocorticoid receptor antagonism, but was prevented by the superoxide dismutase mimetic tempol. CONCLUSIONS/INTERPRETATION We demonstrated that aldosterone deficiency or excess modulates insulin secretion in vivo and in vitro via reactive oxygen species and in a manner that is independent of mineralocorticoid receptors. These findings provide insight into the mechanism of glucose intolerance in conditions of relative aldosterone excess.

Abstract
Background. The long-term efficacy of aldosterone-receptor antagonists (ARAs) as add-on treatment in uncontrolled hypertension has not yet been reported.
Methods. Data from 123 patients (21 with primary aldosteronism, 102 with essential hypertension) with difficult-to-treat hypertension who received an ARA between May 2005 and September 2009 were analyzed retrospectively for their blood pressure (BP) and biochemical response at first followup after start with ARA and the last follow-up available. Results. Systolic BP decreased by 22 ± 20 and diastolic BP by 9.4 ± 12 mmHg after a median treatment duration of 25 months. In patients that received treatment >5 years, SBP was 33 ± 20 and DBP was 16 ± 13 mmHg lower than at baseline. Multivariate analysis revealed that baseline BP and follow-up duration were positively correlated with BP response. Conclusion. Add-on ARA treatment in difficult-to-treat hypertension results in a profound and sustained BP reduction.

How should we manage heart failure developing in patients already treated with angiotensin-converting enzyme inhibitors and beta-blockers for hypertension, diabetes or coronary disease? J Hypertens 2010; 28:1595-8. [PMID: 20613629 DOI: 10.1097/hjh.0b013e32833984b8] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
An increasing number of patients in the community are being treated with angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs) and beta-blockers for hypertension, coronary disease or diabetic renal and vascular complications. Some of these patients will develop heart failure despite such treatment. Based on data from hypertension trials it can be estimated that approximately 5% of treated patients will develop heart failure over 5 years. It is unclear whether patients developing heart failure on and off ACE-inhibitors or beta-blockers, respectively, at the time of heart failure diagnosis have similar prognosis.Treatment options for patients developing heart failure while already treated with ACE inhibitors/ARBs and beta-blockers are very limited if current heart failure guidelines are followed. In this review possible strategies are outlined and important areas for research are identified. It is suggested that trials are designed specifically to address prognosis and treatment in this growing population.

Abstract
In this article, we review the evidence supporting the use of eplerenone for improving cardiovascular prognosis. Activation of the renin-angiotensin-aldosterone system plays a major role in the pathogenesis of heart disease, and blockage of this system has been shown to improve prognosis in several cardiovascular conditions. The 2 marketed aldosterone antagonists, spironolactone and eplerenone, improve prognosis in patients with left ventricular (LV) dysfunction and are effective antihypertensive medications. In addition, a potential role for aldosterone antagonists in the treatment of patients with heart failure and preserved LV function has been suggested and is currently being evaluated in clinical trials. In patients with myocardial infarction having LV dysfunction and evidence of heart failure, eplerenone improves cardiovascular outcomes and attenuates myocardial remodeling. In addition, eplerenone is effective for the treatment of hypertension, where it regresses both LV hypertrophy and proteinuria (2 powerful markers of increased cardiovascular risk). In contrast to spironolactone, eplerenone essentially lacks the sexual side effects that sometimes limit the use of spironolactone. Hyperkalemia is the main potential side effect of eplerenone, especially when used in combination with other medications that can cause hyperkalemia. Adequate patient selection and monitoring are therefore of utmost importance when using this medication. In conclusion, eplerenone is a medication that offers the cardiovascular therapeutic and prognostic benefits of aldosterone antagonism but with fewer side effects compared to spironolactone.
