Filter by:A little attention is paid to the AHT efficacy escaping problem, which can be explained by the AHT correction simplicity and rapid achievement of the target BP level. Nevertheless, modern statistic data on the effective AH treatment described above let us assume that AHT correction is either totally absent or is untimely in case of the "escape" phenomenon development. This could be one of the main reasons for the high prevalence of ineffective AH treatment. The aim of this study is to determine AHT efficacy "escape" phenomenon timeline and its predictors in hypertensive patients.
In the context of physical exercise, there is no evidence of the acute and continued use of beetroot juice with a previously recommended dose of nitrate (NO3) (>300mg) on the cardiovascular performance of hypertensive and postmenopausal women. We will investigate the effects of beetroot juice rich in NO3 acutely (first day: 140mL/800mg) and during a week with daily doses (second to the seventh day: 70mL/400mg) on blood pressure, heart rate (HR), cardiac autonomic control, EF, inflammatory, hormonal, and stress biomarkers oxidative stress and enzymes involved in nitric oxide synthesis and mitochondrial regulation, under resting conditions, as well as mediated by submaximal aerobic exercise sessions. Through a randomized, crossover, triple-blind, placebo-controlled clinical trial, 20 physically inactive hypertensive women will undergo an acute and 7-day trial, each with two intervention protocols: 1) placebo and 2) beetroot; in which will ingest beet juice with or without NO3 in its composition with a 7-day washout interval. On collection days, exercise will be performed on a treadmill for 40 minutes at a speed corresponding to 65-70% of VO2peak. The collection of variables (cardiovascular, autonomic, and blood samples for molecular analyses) of the study will take place at rest (120 minutes after ingestion of the intervention), during exercise (40 minutes), and in the effort recovery stage (during 65 minutes) based on previously validated protocols. The collections were arranged so that the measurement of one variable does not interfere with the other and that they have adequate intervals between them.
This study aims to compare the antihypertensive effect of initial treatment with a single capsule containing quadruple combination of half-dose of blood pressure medicines or standard dose dual combination in patients with hypertension.
The Clinical Decision Support Systems (CDSS) based on real clinical data and its own algorithms can help to make the right choice according to guidelines. The goal of the INTELLECT II study is to investigate treatment adherence to guidelines/science-based medicine and its impact on patient outcomes into two groups of doctors, clinical centers with standard care of treatment (control), and clinical centers using CDSS (active).
The problem of adherence to long-term therapies has been known for years and occurs substantially in all countries, although with greater severity in developing countries. The investigators designed a prospective open study in which 200 patients followed for hypertension at the centers of the Italian Society of Hypertension (SIIA) adhering to the project will be evaluated on the basis of their clinical characteristics, the presence of comorbidities and the therapeutic scheme in place and will be subjected to hair sampling for the analysis of drugs of interest and their possible metabolites in this matrix. The use of the prescribed drugs is recorded along with the relevant clinical parameters and preliminarily evaluated by application of a questionnaire. At the first visit, patients who have been prescribed continuously in the 3 months preceding the study the same active ingredients will be invited to participate in the study, which involves a hair sampling. They will then be prescribed the same active ingredients according to the same scheme if the blood pressure values are within the recommended limits. When more than one antihypertensive drug is present in the therapeutic scheme, they will be prescribed in a single pill, as recommended. For patients with uncontrolled blood pressure, the therapeutic scheme will be modified with the inclusion of other active ingredients and using drug combinations when possible. Patients treated with statins will continue the treatment according to clinical indication using associations with antihypertensive drugs. Patients will be examined and re-tested 3-4 months after the first visit. The use of prescribed medications will be recorded along with clinical parameters of interest and preliminarily evaluated by application of questionnaires. At each of the two visits, the investigating physician will measure blood pressure using a semi-automatic device The 24-hour blood pressure monitoring will be used. Hair extraction ad UHPLC-QQQ/MS analysis will be performed. Concentrations of active ingredient and any metabolites in the keratin matrix are expressed in ng or fractions of ng/mg.
The aim of the study is to assess the improvement of health in patients affected by CKD when they are exposed to non-pharmacological treatment strategies as nutritional program (NP), physical activity program (PA) and mindfulness program (MP), when they are conveyed to the patient by means of digital technologies or not. In the present study, non-pharmacological interventions conveyed by a digital technology (investigational arm) will be compared to a standard, paper-based approach (control arm).
This is a GWAS study that aims to identify possible candidate genes associate to arterial hypertension by exploring single nucleotide polymorphism (SNP) in a group of arterial hypertension, in the Kazakh population. The investigators hypothesize that the careful phenotyping of the subject sand matching with increase the power to find SNP significantly associate with arterial hypertension
It is an observational study in patients with chronic noncommunicable diseases (i.e. cardiovascular diseases, diabetes mellitus, non-alcoholic fatty liver disease, chronic obstructive pulmonary disease and asthma ) and control group with no signs of these conditions. The study has a prospective part planned for 2021 and a retrospective part which includes the patients enrolled between 2018-2020. The aim of the study is to investigate gut microbiota composition, its metabolites, levels of inflammatory and other markers of the disease in prospective groups (arterial hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, asthma, non-alcoholic fatty liver disease and control patients) as well as in retrospective groups (chronic heart failure with preserved and reduced ejection fraction, obstructive atherosclerosis of any vascular bed, arterial hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, asthma, non-alcoholic fatty liver disease, and control patients). Also we are planning to investigate the association between gut microbiota composition and its metabolites, levels of inflammatory and other markers of the disease in retrospective and prospective groups.
The subject of the study is evaluation of factors affecting to exercise intolerance in spiroergometry in women over 40 years of age with hypertension and association and relationship between the parameters of physical performance and prognosis in this group of patients.
Norepinephrine is the vasopressor of choice for the treatment of peri-anesthetic arterial hypotension. The use of this drug at significantly lower concentrations (dilution factor between 40 and 200) than the commercial preparation is increasingly common in the operating room ("baby-noradrenaline"). In addition, dilution errors are potentially serious for the patient (hypertensive peak) The preparation of precise dilutions is an important factor for the safe use of this medically In this study, the investigators wish to compare the dilution method of the protocol with another method of preparation (left to the free choice of the participant).
