Hypertension of Our Patients: Knowledge, Control, Comorbidity

Hypertension

Numerous studies highlight the insufficiency of blood pressure control in treated hypertensive population [1]. As shown in the MONICA study, increased cardiovascular mortality is found in Alsace compared to other french regions. The incidence and prevalence of diabetes and obesity are likely explanatory factors leading to this excess mortality [2]. Furthermore, the incidence and prevalence of alsacian patients with end-stage renal failure (ESRD) is also higher than the national average. The high prevalence of diabetes, hypertension and obesity in this population is also probably responsible for the high prevalence of ESRD [3]. Opportunities to prevent the progression of kidney disease involve an optimal control of treatable evolutionary factors. Beyond control of diabetes and obesity, optimization of blood pressure control are an important factor to consider, as national and international guidelines recommend lower blood pressure targets in this population [4]. Knowledge of the disease and treatment goals are a key component of hypertensive patient management. Studies have shown that the knowledge of hypertensive disease and therapeutic targets were correlated with treatment compliance and with the rate of blood pressure control [5]. Patient education and participation of non-medical actors (nurses, pharmacists, …) are likely to improve the management and treatment compliance of these patients [6]. To our knowledge, no investigation has been performed in our region to determine the epidemiological characteristics, the knowledge level and blood pressure control in the population of hypertensive patients. The main objectives of this observational study are to evaluate, in a treated hypertensive population: the knowledge level of the blood pressure treatment goals, the impact of patient knowledge on this blood pressure control, the potential impact of the patient's comorbidities on his blood pressure control. Such a study should provide the basis for the feasibility of a large survey.

Noninvasive Measurement of Cardiac Output in Pulmonary Hypertension Using Inert Gas Rebreathing...

Pulmonary Hypertension

The study hypothesis is that accuracy of CO measurement by IGR does not differ from classical CO measurement methods such as thermodilution or direct Fick method. This is why the study aims to determine whether non invasive cardiac output (CO) measurement using inert gas rebreathing (IGR)is a suitable method in patients with pulmonary hypertension. In order to examine this, the IGR method will be used in patients undergoing diagnostic or follow-up right heart catheterization.

Renal Denervation for Treatment of Resistant Hypertension in Patients With Chronic Kidney Disease...

HypertensionChronic Kidney Disease

Recent clinical studies have demonstrated that catheter-based renal sympathetic nerve ablation is safe and effective in treating patients with resistant hypertension. However, there is limited data on its safety and efficacy in patients with Chronic Kidney Disease. The investigators hypothesize that catheter-based renal sympathetic nerve ablation is safe and effective in the treatment of resistant hypertension in patients with Chronic Kidney Disease.

Comparison of Ultrafast Echo With Echotracking

Essential Untreated HypertensionHealthy Volunteers

The aim is to compare a new technique for assessing mechanical properties of large arteries: the Ultrafast echo with the reference technique, the echotracking. This will be done by studying in parallel hypertensive patients and controls with both techniques and this will revisit old concepts of increased stiffness in hypertensive arteries.

Prevalence of Pulmonary Hypertension (PAH) in Patients With Thalassemia

Thalassemia MajorThalassemia Intermedia1 more

This is a multicenter observational case-control analysis lasting 12 months aimed at determining the prevalence of pulmonary hypertension (PAH) in patients with Thalassemia Major and Intermedia. The patients will be followed, treated and examined according to the best standard clinical practice dictated by the Italian Society for the study of Hemoglobinopathies (SITE), Thalassemia International Federation (TIF)and the Task Force for Diagnosis and Treatment of Pulmonary Hypertension of European Society of Cardiology (ESC); European Respiratory Society (ERS); International Society of Heart and Lung Transplantation (ISHLT) guidelines.

Relationship of Urine Sodium Excretion to Central Blood Pressure and Aortic Pulse Wave Velocity...

Hypertension

One interesting area is the relationship of high salt intake and central aortic blood pressure. High salt intake is associated development of hypertension and cardiovascular mortality. Central aortic pressure is better correlated with cardiovascular events and mortality. With recent advances in technology, it is possible to measure central aortic pressure noninvasively and easily. Until now there is no study to evaluate the relationship of high salt intake and aortic blood pressure. The purpose of the present study is to evaluate the relationship of high salt intake and aortic blood pressure and aortic stiffness. Subjects with or without hypertension will be enrolled for investigation. Subjects with hypertension should be never treated with antihypertensive medications. Subjects with secondary hypertension, diabetes, heart failure, high grade kidney disease, ischemic heart disease, and major arrhythmia will be excluded. Sodium intake is measured by 24 hour urinary sodium excretion, with the measurement of peripheral and central aortic blood pressure, and aortic pulse wave velocity. Salt sensitive hypertension related single nucleotide polymorphism will be analyzed to define the relationship with high salt intake and aortic pressure and pulse wave velocity.

Telmisartan 80mg+Hydrochlorothiazide (HCTZ) 25 mg in Hypertension: an Observational Study

Hypertension

It is a national, retrospective , observational study in hypertensive patients treated for at least 8 weeks with the fixed dose combination of telmisartan 80 mg and hydrochlorothiazide 25 mg. The primary objective is to assess the control rate (systolic and diastolic blood pressure). Key secondary objectives are to assess the blood pressure reduction after at least 8 weeks of treatment, describe the population treated with this new fixed dose combination

Using Multimedia Technology for Hypertension Control for Low-Income African Americans

Hypertension

The purpose of this study is to test an interactive DVD intervention to encourage patients to stick to their blood pressure medication in order to achieve blood pressure control for African American patients. The intervention will convey health messages through personal patient stories who have dealt with or continue to struggle with high blood pressure. Hypothesis 1: At the end of 9 months a higher proportion of patients randomized to the intervention group will achieve appropriate blood pressure control. Hypothesis 2: At the end of 9 months a higher proportion of patients who randomized to the intervention group will report high adherence to their hypertension medications.
