BACKGROUND AND AIM:: Ambulatory blood pressure monitoring (ABPM) is superior to conventional BP measurement in predicting outcome, with baseline 24-h, daytime and night-time absolute values, as well as relative nocturnal decline, as powerful determinants of prognosis. We aimed to evaluate ABPM estimates on the appearance of cardiovascular events and mortality ...

Resistant hypertension is a prevalent dilemma. Despite all available antihypertensive medications and multiple strategies such as healthier diets and exercise programs, many patients are still unable to maintain or reach a therapeutic goal for systolic blood pressure. Because of this major health concern, CVRx, Inc has developed a treatment involving ...

Pulmonary hypertension is a disorder characterized by an increase in mean pulmonary arterial pressure (mPAP > 25 mmHg), which is responsible for the transport of blood from the heart to the lungs. Increased pressure leads to decreased flow of blood through the lungs and decreased oxygen deliverance throughout the body. ...

Several lines of evidence show that blood pressure (BP) control in treated hypertensive patients is largely unsatisfactory and that this depends on a variety of factors, such as the poor patient's compliance, insufficient use of combination drug treatment as well as true difficulties in achieving well controlled BP. This review ...

Aldosterone hypersecretion in primary aldosteronism is unilateral (aldosterone producing adenoma and primary unilateral hyperplasia) or bilateral (idiopathic adrenal hyperplasia). Lapa-roscopic adrenalectomy is nowadays the preferred approach to treat patients with unilateral primary aldosteronism. We review the outcomes of this intervention in recently published series. Laparoscopic adrenalectomy has a morbidity of ...

The recommendations of international scientific societies for the treatment of hypertension in the geriatric population are different. Lack of outcome trials, non-standardised terminology as well as differing levels of evidence contribute to the inconsistencies in the guidelines. This review article compares six international guidelines (ESH-ESC 2007/2009, SHG 2009, DHL 2008, CHEP ...

The prevalence of hypertension among the paediatric population is 1%-2%. The emergency physician should recognise potentially harmful blood pressure (BP) levels and ensure they are adequately treated, in order to avoid life-threatening complications. A hypertensive emergency is a severely elevated BP complicated by target organ dysfunction (cardiovascular, cerebrovascular and/or renal). ...

Background: Pulmonary hypertension (PH) is considered a risk factor for morbidity and mortality in patients undergoing heart transplantation. Medical therapy with oral and pharmacologic agents is not always effective in reducing pulmonary artery (PA) pressures. Left ventricular assist devices (LVADs) have been used to reduce PA pressures in cases of ...

Patients with end stage renal disease on hemodialysis are at risk for cardiovascular events and increased mortality. Hypertension contributes to these risks and can be difficult to assess due to unreliable blood pressure (BP) measurements at dialysis centers. A clinical practice grant from the American Nephrology Nurses'Association allowed for the ...

Hypertension and renal disease are closely related. In fact, there is an inverse linear relationship between renal function and prevalence of hypertension. Hypertensive patients with renal dysfunction exhibit a poor clinical profile, which markedly increases their risk for cardiovascular outcomes. This review considers the available evidence on the best therapeutic ...

Renin-angiotensin-system (RAS) activation plays a key role in the development of hypertension and cardiovascular disease. Drugs that antagonize the RAS (angiotensin-converting enzyme [ACE] inhibitors and angiotensin receptor blockers [ARBs]) have proven clinical efficacy in reducing blood pressure values and cardiovascular morbidity and mortality. ACE inhibitors partially inhibit plasma ACE, and ...

Concerns about metabolic complications often disturb prolonged use of diuretics in Japan. We investigated 3-year safety and efficacy in Japanese patients with hypertension who were uncontrolled with angiotensin receptor blocker or angiotensin-converting enzyme inhibitor regimens and then switched to losartan (50 mg)/hydrochlorothiazide (12.5 mg; HCTZ) combinations. Blood pressure decreased favorably ...

Normal-pressure hydrocephalus (NPH) arises in adulthood and is characterized by a typical combination of clinical and radiological findings. The mean basal intracranial pressure is normal or mildly elevated. The typical signs of the disease are gait impairment, urinary incontinence, and dementia. The difficulty of distinguishing NPH from other neurodegenerative disorders ...

Azilsartan-chlorthalidone fixed combination is a new drug in the management of hypertension. Azilsartan has been shown to have greater blood pressure-lowering effects than other angiotensin-receptor blockers (ARBs), and the debate regarding the superiority of chlorthalidone over hydrochlorothiazide has been ongoing for years. The combination is unique because it is the ...

Hypertension is a growing global health problem, and is predicted to affect 1.56 billion people by 2025. Treatment remains suboptimal, with control of blood pressure achieved in only 20%-35% of patients, and the majority requiring two or more antihypertensive drugs to achieve recommended blood pressure goals. To improve blood pressure ...
Borghi Claudio - - 2012
Hypertension is one of the most important and widespread risk factors for the development of cardiovascular disease. Once, combination therapy was traditionally reserved as a third-line or fourth-line approach in the management of hypertension. However, several major intervention trials in high-risk patient populations have shown that an average of 2-4 ...

Some antihypertensive drugs have also renoprotective and anti-inflammatory properties that go beyond their effect on blood pressure. It has been suggested that microalbuminuria and glomerular filtration rate (GFR) are associated with circulating levels of the soluble form of the receptor, sRAGE (soluble receptor for advanced glycation ends-products). In the present ...

Neuropathy, peripheral arterial occlusive disease and microvascular disturbances are important factors contributing to foot problems in diabetic patients. In the diabetic foot with ischemia, the alterations in skin microvascular function are pronounced including severely reduced capillary circulation and abolished hyperaemic responses. These microvascular disturbances, which are superimposed on the already ...

: Risk factor modification plays an important role in recurrent stroke prevention. These modifiable risk factors tend to cluster in stroke patients, but for a significant subgroup the only identifiable risk factor is high blood pressure or chronic hypertension. This article reviews the current evidence for management of blood pressure ...

We investigated the effect of reducing mitochondrial oxidative stress by the mitochondrial-targeted antioxidant peptide SS-31 in hypertensive cardiomyopathy. Oxidative stress has been implicated in hypertensive cardiovascular diseases. Mitochondria and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase have been proposed as primary sites of reactive oxygen species (ROS) generation. The mitochondrial targeted ...

BACKGROUND: Arterial stiffness is an independent predictor of cardiovascular events and mortality in hypertensive patients. The influence of different antihypertensive drug classes on improving arterial stiffness beyond blood pressure reduction is not widely available. We aimed to determine whether the artery stiffness can be improved because of antihypertensive treatments independently ...
