About this study

This Registry is an investigator-initiated, international, multicenter, observational, prospective study aiming at: i) evaluating non-invasive 24-h ambulatory blood pressure and arterial stiffness estimates (through 24-h pulse wave analysis) in hypertensive subjects; ii) assessing the changes in estimates following treatment; iii) weighing the impact of 24-h pulse wave analysis on target organ damage and cardiovascular prognosis; iv) assessing the relationship between arterial stiffness, blood pressure absolute level and variability, and prognosis. Approximately 2000 subjects, referred to 20 hypertension clinics for routine diagnostic evaluation and follow-up of hypertension, will be recruited. Data collection will include ambulatory blood pressure monitoring, performed with a device allowing simultaneous non-invasive assessment of blood pressure and arterial stiffness, and clinical data (including cardiovascular outcomes). A web-based telemedicine platform will be used for data collection. Subjects will visit the centers at 6-12 month intervals. First follow-up results are expected to be available in the next 2-years. The results of the Registry will help defining the normalcy thresholds for current and future indices derived from 24-h pulse wave velocity, according to outcome data. They will also provide supporting evidence for the inclusion of such evaluation in recommendations on hypertension management.

Read the detailed description

The VASOTENS Registry is an international, multicenter, observational, prospective project Actually, it is a large database of ambulatory blood pressure recordings obtained with a non-invasive device, able to determine central blood pressure and various indices of arterial stiffness (mainly pulse wave velocity and augmentation index) over the 24-hours, based on a clinically validated technology of pulse wave analysis of oscillometric blood pressure measurements, integrated in an ambulatory blood pressure monitor. Specifically, this project aims at creating an international network of centers performing ambulatory blood pressure monitoring and arterial stiffness monitoring, in order to evaluate the impact of such estimates on the clinical outcome of hypertensive patients. The results of the data collected at baseline and during regular follow-up of hypertensive patients (up to 2 years) will help to provide evidence on the clinical usefulness of such technologies for the screening and follow-up of the hypertensive patients. The registry will include data from subjects fulfilling the inclusion criteria and whose data are contained in existing databases collected by the participating centers and who are regularly followed-up at the center. New subjects can be enrolled for this project, but they must be submitted to ambulatory blood pressure monitoring because it is required for evaluating their hypertension status, according to current recommendations. Data collection is ensured by a dedicated web-based telemedicine platform, including an electronic case report form (e-CRF). The e-CRF allows collection of patient's clinical data, such as family history, anthropometric data, habits, past and current diseases, therapies, office blood pressure, and laboratory tests, including evaluation of target organ damage. The project does not involve any type of intervention related to the study and the physicians can manage the patients included in the Registry according to the requirements of clinical practice and current guidelines. However, as recommended by current guidelines, each patient has to be followed-up with visits occurring at regular intervals (ideally every 6 months, and not less than once a year). The physicians is also free to use the ambulatory blood pressure data in the clinical management of the patients. At least 30 Hypertension centers are planned to be involved in the project, each one providing at least 100 patients, which have to be followed-up over time. Centers will be selected in different countries, initially in Europe, starting from Italy and Russia. Mandatory criteria of a center to be included in the study are the availability in the facility of a BPLab ambulatory blood pressure monitor, the potential for providing and properly following-up the number of patients required by the protocol, the availability of Internet connection, regular access to the web and human resources to upload ambulatory blood pressure and clinical data.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 24-hour Pulse Wave Velocity (PWV)

    24-hour average value for arterial stiffness was assessed through estimation of the time traveled by the pulse wave from the central arterial tree (aorta) to the peripheral arteries (brachial artery) and measured in meters per sec. The faster the wave travels through the arterial tree, the stiffer the artery is.

    Measured: 2 years

  2. 24-hour Augmentation Index (AI)

    24-hour average value for waves reflection expressed as a percentage. The augmentation index is a measure of wave reflection and arterial stiffness and is commonly measured as the ratio of the central pulse pressure and the reflected pulse pressure which augments the central blood pressure. When arteries are stiff, a reflected wave is formed where arteries split. This reflected wave moves back at the heart and increases the pressure at which the heart has to pump. The higher the index the stiffer the artery is.

    Measured: 2 years

  3. 24-hour Central Blood Pressure

    24-hour average central aortic pressure expressed in mmHg, as the estimated blood pressure at the level of the thoracic aorta

    Measured: 2 years

Secondary outcomes (6)
  1. 24-hour Systolic Blood Pressure

    Average 24-hour brachial systolic blood pressure (mmHg), namely the systolic blood pressure measured at the level of the brachial artery (upper arm).

    Measured: 2 years

  2. 24-hour Diastolic Blood Pressure

    Average 24-hour brachial diastolic blood pressure (mmHg), namely the diastolic blood pressure measured at the level of the brachial artery (upper arm).

    Measured: 2 years

  3. Cardiac Damage (Left Ventricular Hypertrophy at Echocardiogram or ECG)

    Left ventricular mass indexed by body surface area (g/m^2) is used to identify left ventricular hypertrophy in case it is increased above a certain threshold (see protocol).

    Measured: 2 years

  4. Vascular Damage (Carotid Plaque at Ultrasonography)

    Intima media tickness (mm) measured by carotid ultrasonography is used to identify wall thickening or atherosclerotic plaque, when it is above a certain threshold (see protocol).

    Measured: 2 years

  5. Renal Damage (Urine Protein)

    Urine proteine (mg/24h). The increase above a certain threshold of urine protein is a sign of renal damage (see protocol).

    Measured: 2 years

  6. Combination of Non-fatal and Fatal CV and Renal Events or All-cause Death

    The outcome variables consisted of a combination of nonfatal (i.e., not causing death) and fatal events (i.e., causing death) and all-cause death. The outcome variables included transient ischemic attack (TIA) or stroke (ischemic or hemorrhagic), myocardial infarction, angina pectoris or coronary revascularization, heart failure, peripheral vascular disease, and renal failure.

    All outcomes were recorded by the Investigator on the date of the first occurrence or on the last study visit.

    Measured: 4 years
