Retina Microvascular Remodeling and Cognitive Function In Hypertension

HypertensionMild Cognitive Impairment

This study aims to determine the relationships between retina micro-vascular remodeling and cognitive function in hypertensive patients. The study plans to enrol 160 patients (100 patients with mild cognitive impairment -MCI- and 60 without MCI).

Loop Diuretic Therapy in Acutely Decompensated Heart Failure

Acute Heart Failure

DiurHF is a prospective, multicenter, observational, study that compares continuous with intermittent infusion of furosemide in patients admitted with a diagnosis of ADHF. Previous pilot study design was planned to anticipate a larger multicenter trial able to definitively evaluate the optimal loop diuretic use strategy in patients with ADHF.

Radial Artery Spasm Leading to Occlusion in Patients Undergoing Coronary Angiogram Via Radial Access...

Arterial OcclusionArterial Spasm

Radial artery access is increasingly becoming popular among interventional cardiologists for patients undergoing percutaneous coronary intervention(PCI)/ diagnostic angiography secondary to its low complications rates. However, it is frequently associated with the spasm of the radial artery which can lead to difficulty in catheter manipulation during the procedure and potentially leading to vessel trauma. This vessel trauma can cause activation of coagulation system and formation of clot and subsequently the occlusion of radial artery. In this study the investigators intend to find the association of radial artery spasm with the future development of radial artery occlusion in patients who undergo PCI via radial access.

International Registry for Ambulatory Blood Pressure and Arterial Stiffness Telemonitoring

Hypertension

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.

Magnetic Resonance Venography Pre- and Post-Treatment in Patients With Idiopathic Intracranial Hypertension...

Pseudotumor Cerebri

This prospective study will use magnetic resonance imaging of patients with Idiopathic Intracranial Hypertension (IIH), to determine if the common radiological finding of transverse venous sinus stenosis can be reversed with standard of care medical treatment of IIH.

Atherosclerosis in Atrial Fibrillation

Atrial FibrillationMetabolic Syndrome4 more

The prevalence of metabolic syndrome in patients suffering from non valvular atrial fibrillation is derived from studies regarding recurrences of atrial fibrillation after catheter ablation. Prospective studies in european countries are lacking. Furthermore, the impact of metabolic syndrome on cardiovascular events in patients with non valvular atrial fibrillation is still unknown.
