Active clinical trials for "Hypertension"

Losartan is an antihypertensive drug belonging to the ARB family. It is characterized as the substrate of the Multi Drug Resistance-1 (MDR1) drug-efflux protein (a pump that ensures the removal of drugs/foreign substances out of the cell) encoded by the ATP Binding Cassette Subfamily B Member 1 (ABCB1) gene. A recent line of evidence indicates that potential polymorphisms in this gene tend to alter the absorption, transport, bioavailability of losartan, and, indirectly, its effectiveness in hypertension control. As identified by new research, the C3435T, G2677T, and C1236T polymorphic alleles of the MDR1 gene might alter the bioavailability and thus the effectiveness of losartan

The apelin-APJ signaling pathway has emerged as an important novel mediator of cardiovascular control and blood pressure homeostasis. Genetic variation in apelin and its receptors likely contributes to essential hypertension, in addition to a range of traditional risk factors. Thus, a study will be conducted on Syrian patients with hypertension and coronary artery disease to investigate some of the single polymorphisms in the apelin gene and its receptor that may be responsible for the development of these diseases, and to link the levels of this peptide and its receptor in the blood with these polymorphisms and the percentage of these diseases (as shown by many Modern Global Reference Studies).

This observational study will involve analysis of data collected by the National Rare Disease Registry or medical records .The study will describe outcomes only in PAH(Pulmonary arterial hypertension) patients treated with sildenafil; there will be no comparison with another treatment group. Approximately 100 adults with PAH will be recruited in China hospitals This NIS(non-interventional study) data will be recorded by a physician in the medical records, during the patients' clinical visits, and in the electronic Case Report Forms (CRF).

The coronavirus disease 2019 (COVID-19) pandemic has uprooted conventional health care delivery for routine ambulatory care, requiring health systems to rapidly adopt telemedicine capabilities. The digital divide, has been well documented with lower rates of technology and broadband adoption among racial/ethnic minorities. Additionally, Black patients suffer a disproportionate burden of hypertension and cardiovascular disease. This study will implement a text-based home hypertension monitoring program among Black Medicaid patients with hypertension and cardiovascular disease (CVD) and compare its uptake to the currently available blood pressure monitoring program using the patient portal that is integrated into the electronic health record (EHR).

This is a multicenter, prospective observational cohort study. It will compare effectiveness and safety of various add-on treatment options in regard to arterial blood pressure control in adult patients with treatment resistant hypertension: an aldosterone receptor blocker (e.g. spironolactone), a loop diuretic, a thiazide in large daily dose, an alpha 1 selective blocker or a beta 1 selective blocker. The add-on therapy will be prescribed to the patients within the scope of their routine medical care, independently from the study investigators. The patients will be followed up for 6 months, with monthly visits and continuous home blood pressure diary kept by the patients themselves.

The current guideline of asymptomatic severe hypertension (ASH) treatment in emergency department (ED) recommends through low level of evidence that the patients should not be rapidly decreased their BP in ED but instead receive oral antihypertensive treatment and close outpatient follow-up is needed. Unfortunately, there was some ambiguity in the time point of BP measurement in ED described in the past literature because high BP on ED admission may significantly decrease within hours without any medications. The importance of pre-ED discharge BP, which can still be critically high, that may affect the follow-up outcome has never been investigated. The study aim of this study is to evaluate the physicians' treatment strategies as well as immediate clinical outcomes between patients with severely- and moderately-elevated pre-discharge BP after management of ASH its in ED during the recent recommendation. The secondary outcome is to compare the BP at follow-up in these two groups.

This study will help to provide more up to date prognostic data on the natural history of untreated proximal CTEPH which will be helpful in discussions regarding surgical versus medical treatment and by exploring the similarities and differences between distal CTEPH and IPAH the investigators hope to get insights into disease mechanisms in patients with distal CTEPH.

The purpose of this study is to estimate antihypertensive effect of azilsartan medoxomil (Edarbi®) therapy on blood pressure in participants with overweight or obesity in routine clinical practice of hypertension (HTN) treatment in the Russian Federation and in the Republic of Kazakhstan..

The TOPP-2 registry is an international, non-interventional, prospective registry including children and adolescents newly diagnosed with pulmonary hypertension (PH) to gain further insights in the disease course and long-term outcome of PH in childhood. Patients will undergo clinical assessments and receive standard medical care, as determined by treating physicians in their daily clinical practice. The TOPP-2 registry is specifically designed to capture the variables that have been proposed as treatment goals in PePH and the reasons for changes in treatment strategy. The TOPP-2 registry uses the new clinical classification of PH as outlined at the 5th World Symposium for Pulmonary Hypertension (WSPH) in Nice 2013 and includes new characterizations for children with PH. The registry is planned and implemented under the scientific leadership of the Association for Pediatric Pulmonary Hypertension (PePH), independently from the financial sponsors. All enrolled patients will have a follow-up period of 18 months.

Randomised two parallel groups multicenter study using a Prospective Randomised Open Blinded End-point design (PROBE), aiming at comparing the efficacy of a therapeutic strategy targeting the normalisation of arterial stiffness for reducing cardiovascular (CV) and renal events, in comparison with a classical therapeutic strategy implementing the European Society of Hypertension-European Society of Cardiology (ESH-ESC) Guidelines, in patients with essential hypertension and medium-to-very high CV risk.
