BACKGROUND: Renin-angiotensin aldosterone system (RAAS) inhibitors significantly improve outcome in heart failure (HF) patients with reduced ejection fraction (HFREF), irrespective of the occurrence of worsening renal function (WRF). However, in HF patients with preserved ejection fraction (HFPEF), RAAS inhibitors have not been shown to improve outcome but are still frequently prescribed. METHODS AND RESULTS: Random effect meta-analysis was performed to investigate the relationship between RAAS inhibitor therapy, WRF in both HF phenotypes, and mortality...

Hypertension affects over 1.2 billion individuals worldwide and has become the most critical and expensive public health problem. Hypertension is a multifactorial disease involving environmental and genetic factors together with risk-conferring behaviors. The cause of the disease is identified in ∼10% of the cases (secondary hypertension), but in 90% of the cases no etiology is found (primary or essential hypertension). For this reason, a better understanding of the mechanisms controlling blood pressure in normal and hypertensive patients is the aim of very active experimental and clinical research...

OBJECTIVES: There is a growing evidence of increased risk of cerebrovascular events in primary aldosteronism (PA). Nevertheless, acute neurologic ailment as presenting feature of PA is uncommon. Our aim is to highlight the diagnosis challenges in stroke unmasking PA and to discuss the underlying physiopathology and management dilemmas. MATERIALS AND METHODS: We hereby describe three consecutive rare cases of stroke revealing PA. All patients had brain imaging and thorough biological and morphological assessment to rule out other etiologies of stroke...

Arterial stiffness is associated with cardiovascular risk, morbidity, and mortality. The present paper reviews the main vitamins related to arterial stiffness and enabling destiffening, their mechanisms of action, providing a brief description of the latest studies in the area, and their implications for primary cardiovascular prevention, clinical practice, and therapy. Despite inconsistent evidence for destiffening induced by vitamin supplementation in several randomized clinical trials, positive results were obtained in specific populations...

Adrenal venous sampling is the most reliable diagnostic procedure to determine surgical indications in primary aldosteronism. Because guidelines recommend multidetector computed tomography (CT) to evaluate the adrenal gland, some past reports used multidetector CT as a guide for adrenal venous sampling. However, the detailed anatomy of the right adrenal vein and its relationship with an accessory hepatic vein remains uncertain. The purpose of this study was to describe detailed anatomical variations of the right adrenal vein and to determine the concordance between CT and catheter venography in patients with primary aldosteronism...

We evaluated the influence of catheter sampling position and size on left adrenal venous sampling (AVS) in patients with primary aldosteronism (PA) and analyzed their relationship to cortisol secretion. This retrospective study included 111 patients with a diagnosis of primary aldosteronism who underwent tetracosactide-stimulated AVS. Left AVS was obtained from two catheter positions - the central adrenal vein (CAV) and the common trunk. For common trunk sampling, 5-French catheters were used in 51 patients, and microcatheters were used in 60 patients...

BACKGROUND: Previous studies showed higher risk of cardiovascular and cerebrovascular (CCV) events in primary aldosteronism compared with essential hypertension, but the patients of these studies were limited to primary aldosteronism patients with high plasma aldosterone concentration (PAC). The introduction of the aldosterone-renin ratio as the screening test for primary aldosteronism led to the recognition of primary aldosteronism patients with normal PAC (nPA). However, there is no information on the risk of primary aldosteronism including nPA...

BACKGROUND: Recent studies have revealed a higher rate of cardiovascular complications in primary aldosteronism (PA) compared to patients with essential hypertension (EH). Asymmetric dimethylarginine (ADMA) is a marker of endothelial dysfunction that could contribute to increased cardiovascular risk in patients with PA. OBJECTIVES: The aim of this study was to compare the levels of ADMA among patients with PA, controls with EH and healthy participants. Methods: Serum ADMA levels were determined, using commercially available competitive enzyme-linked immunosorbent assay...

The endothelium, which is at the interface between circulating blood and the vascular wall, comprises a simple squamous layer of cells that lines the inner surface of all blood vessels. Endothelial cells are highly metabolically active and play an important role in many physiological functions, including control of vasomotor tone, blood cell trafficking, vascular permeability, and maintenance of vascular integrity (Mensah, Vascul Pharmacol 46(5):310-314, 2007; Yetik-Anacak and Catravas, Vascul Pharmacol 45(5):268-276, 2006)...

Conflicting data have been published on the effects of aldosterone excess on glucose metabolism. Specifically, there are limited data on whether adrenalectomy in patients with aldosterone-producing adenomas (APA) can improve glucose metabolism. In this study we evaluated changes in glucose metabolism, before and after surgery for APA. The subjects were 61 patients treated with unilateral adrenalectomy, localized by adrenal venous sampling. A 75g-oral glucose tolerance test (OGTT) was performed before and 1 year after adrenalectomy...

In the normal human adrenal gland, serotonin (5-HT) stimulates aldosterone secretion through the 5-HT4 receptor (5-HT4R). However, the physiological role of the serotonergic control of adrenocortical function is not known. In the present study, we have investigated the ability of l-Lysine, which has been shown to act as a 5-HT4 receptor antagonist, to counteract in vitro and in vivo the stimulatory effect of 5-HT4R agonists on aldosterone production. l-Lysine was found to inhibit aldosterone production induced by 5-HT and the 5-HT4R agonists BIMU8 from cultured human adrenocortical cells...

Constitutive activation of the Wnt pathway/β-catenin signaling may be important in aldosterone-producing adenoma (APA). However, significant gaps remain in our understanding of the prevalence and clinical outcomes after adrenalectomy in APA patients harboring CTNNB1 mutations. The molecular expression of CYP11B2 and gonadal receptors in adenomas were also explored. Adenomas from 219 APA patients (95 men; 44.2%; aged 50.5 ± 11.9 years) showed a high rate of somatic mutations (n = 128, 58.4%). The majority of them harbored KCNJ5 mutations (n = 116, 52...

Variants in G protein-coupled inward rectifier K(+) channels 4 (GIRK4 also known as KCNJ5) gene are associated with primary aldosteronism, which is the most common cause of secondary hypertension. The KCNJ5 rs2604204 variant was shown to be common (minor allele frequency=32.5%) in Chinese patients with essential hypertension (EH). The relationship between KCNJ5 variant and plasma aldosterone (ALD) levels in EH patients has not been reported. We collected 229 patients with newly diagnosed EH without any antihypertensive agents...

Primary aldosteronism (PA) is a rare disorder. The majority of patients with PA present with typical features and are easily diagnosed. This disorder is usually diagnosed with hypokalemia, hypertension or an adrenal mass. However, patients with atypical symptoms may present a challenge for diagnosis and treatment. In the present study, a case of PA is described that presented with hypokalemic myopathy simulating polymyositis. The patient was a 44-year-old woman who presented with weakness and difficulty walking...
