Nutraceuticals and blood pressure control: A European Society of Hypertension position document

2020

: High-normal blood pressure (BP) is associated with an increased risk of cardiovascular disease, however the cost-benefit ratio of the use of antihypertensive treatment in these patients is not yet clear. Some dietary components and natural products seems to be able to significantly lower BP without significant side effects. The aim of this position document is to highlight which of these products have the most clinically significant antihypertensive action and wheter they could be suggested to patients with high-normal BP. Among foods, beetroot juice has the most covincing evidence of antihypertensive effect. Antioxidant-rich beverages (teas, coffee) could be considered. Among nutrients, …

Should reduction of increased short‐term blood pressure variability be a target of antihypertensive therapy?

2021

Abstract It has long been known that blood pressure (BP) is characterized by marked short‐term fluctuations occurring within a 24‐h period and also by long‐term oscillations occurring over more prolonged periods of time. An increased short‐term blood pressure variability (BPV) appears to importantly contribute to target organ damage and to the enhanced cardiovascular risk of hypertensive patients, over and above the effect of an increase in mean BP levels. Reducing 24‐h mean BP is the main aim of antihypertensive therapy, but initial data are available that additional cardiovascular protection can be achieved by reducing BPV. However, to definitively prove the prognostic role of short‐term …

Influence of metabolic syndrome on hypertension-related target organ damage

Long-term cardiac pro-B-type natriuretic peptide gene delivery prevents the development of hypertensive heart disease in spontaneously hypertensive r…

2011

Background— Diastolic dysfunction associated with high blood pressure (BP) leads to cardiac remodeling and fibrosis and progression to congestive heart failure. B-type natriuretic peptide (BNP) has BP-lowering, antifibrotic, and antihypertrophic properties, which makes BNP an attractive agent for attenuating the adverse cardiac remodeling associated with hypertension. In the current study, we tested the effects of sustained cardiac proBNP gene delivery on BP, cardiac function, and remodeling in spontaneously hypertensive rats (SHR). Methods and Results— We used the myocardium-tropic adeno-associated virus serotype 9 (AAV9) vector to achieve continuously enhanced cardiac rat proBNP expressi…

Alcohol-Mediated Renal Sympathetic Neurolysis for the Treatment of Hypertension: The Peregrine™ Infusion Catheter.

2020

Renal sympathetic denervation using conventional non-irrigated radiofrequency catheters has potential technical shortcomings, including limited penetration depth and incomplete circumferential nerve damage, potentially impacting therapeutic efficacy. Against this background, second generation multi-electrode, radiofrequency and ultrasound renal denervation systems have been developed to provide more consistent circumferential nerve ablation. Irrigated catheters may allow deeper penetration while minimizing arterial injury. In this context, catheter-based chemical denervation, with selective infusion of alcohol, a potent neurolytic agent, into the perivascular space, may minimize endothelial…

AISF position paper on liver disease and pregnancy.

2016

Abstract The relationship between liver disease and pregnancy is of great clinical impact. Severe liver disease in pregnancy is rare; however, pregnancy-related liver disease is the most frequent cause of liver dysfunction during pregnancy and represents a severe threat to foetal and maternal survival. A rapid differential diagnosis between liver disease related or unrelated to pregnancy is required in women who present with liver dysfunction during pregnancy. This report summarizes the recommendation of an expert panel established by the Italian Association for the Study of the Liver (AISF) on the management of liver disease during pregnancy. The article provides an overview of liver disea…

Performance of micellar mobile phases in reversed-phase chromatography for the analysis of pharmaceuticals containing beta-blockers and other antihyp…

1996

A rapid and simple reversed-phase micellar liquid chromatographic procedure for the simultaneous determination of the beta-blockers atenolol, metoprolol and oxprenolol, the diuretics amiloride, bendroflumethiazide, chlorthalidone and hydrochlorothiazide and the vasodilator hydralazine in pharmaceuticals, is proposed. An interpretive optimization procedure, which uses the chromatographic data for only five mobile phases, was applied to select a suitable micellar mobile phase. A comparative study was also made of the performance of micellar and aqueous-organic mobile phases in the analysis of pharmaceuticals that combine beta-blockers and diuretics. The determination of all the drugs could be…

Cardiac Remodeling According to the Nocturnal Fall of Blood Pressure in Hypertensive Subjects: The Whole Assessment of Cardiac Abnormalities in Non-D…

2021

Objective: Several epidemiological studies suggest that the preservation of the physiological circadian rhythm of blood pressure or its disruption affects the extent of the organ damage developed by the patient. If we classify the circadian rhythm of blood pressure into four nocturnal profiles, significant differences emerge in terms of organ damage burden and prognosis: reverse dippers have the worst prognosis while dippers and mild dippers fall into an intermediate risk range. The risk profile of extreme dippers is still debated, and the available data are very conflicting and inconclusive. Starting from this gap of knowledge, we aimed to evaluate, retrospectively, in a cohort of hyperten…

Evidences from Clinical Trials and Use of Antihypertensive Drugs in Children and Adolescents

2019

In adults, when prescribing antihypertensive therapy, decisions regarding the choice of agent can be based upon evidence from clinical trials in large numbers of subjects, many of these having compared one class of agent with another. Whilst increased emphases on conducting drug trials in children and adolescents over the past 25 years have yielded important advances, and have tested the efficacy and safety of the various classes of antihypertensive agents, there remains a general lack of high quality long-term outcome data to guide choice of drug therapy for pediatricians managing HTN. As of today, certain clinical trials in children and adolescents have established the pharmacokinetics, p…

Impact of Metabolic Syndrome on Coronary Microvascular Dysfunction: A Single Center Experience

2023

Coronary microvascular dysfunction (CMD) represents a widespread condition and a prevalent cause of ischemic heart disease. Total TIMI frame count (TTFC) can be a good indicator of CMD in different populations. The aim of our study was to evaluate the incidence of CMD in different populations such as METS patients compared with diabetic and hypertensive patients. The study was carried out on patients with chest pain and/or positive stress test and angiographically undamaged coronary arteries. Our CMD population was divided into three subgroups; patients with arterial hypertension, patients with type II diabetes mellitus and patients with metabolic syndrome. TIMI Frame Count (TFC) and Myocar…
