There are about 21062 clinical studies being (or have been) conducted in Italy. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of the study is to assess the efficacy of an individualized approach to duration of antibiotic therapy based on each subject's clinical response compared to a local standard approach in patients coming from the community and who are hospitalized because of a pneumonia.
No previous study has assessed the potential of ranolazine to interfere with levels of platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy. Aim of this study is to compare the pharmacodynamic effects of maintenance doses of ranolazine versus amlodipine on platelet reactivity in patients with coronary artery disease who are treated with dual antiplatelet therapy.
Pharmacologic alternatives in statin-intolerant patients include ezetimibe and nutraceuticals (i.e. compounds derived from foods with cholesterol lowering actions). The investigators will compare the efficacy and tolerability of ezetimibe versus a nutraceutical-based protocol in statin-intolerant patients treated with percutaneous coronary intervention.
Twelve-month, multicenter, intra-subject controlled (retrospective-prospective), open-label, active-treatment study to evaluate the dose-response and pharmacokinetics (PK) of cinacalcet HCl for the treatment of Secondary Hyperparathyroidism (SHPT) in paediatric subjects with chronic kidney disease (CKD) on dialysis, followed by 12-month study extension.
Patients with NSTEMI and multivessel disease will be scheduled to undergo early invasive strategy (PCI within 72 hours) of de novo native coronary artery lesions were considered for recruitment into the study. Inclusion criteria are the following: diagnosis of NSTEMI according to current guidelines presenting with multivessel disease. We will exclude patients with cardiogenic shock at presentation (systolic blood pressure <90 mmHg despite drug therapy), left main coronary disease (>50% diameter stenosis), previous coronary artery bypass grafting (CABG) surgery, patients with Syntax Score >32 and candidated to by-pass surgery (10), severe valvular heart disease and unsuccessful procedures. Procedure success was defined as the achievement of an angiographic residual stenosis of less than 30% and a thrombolysis in myocardial infarction (TIMI) flow grade III after PCI. Patients randomized to One-Stage group were completely revascularizated in one time PCI, whereas patients randomized to Multi-Staged group were completely revascularizated in more time PCI, during the same hospitalization. Patients received a clopidogrel loading dose of 600 mg before the PCI (for loading dose administered more than 6 h prior to procedure). Post-procedural antiplatelet regimen consisted of aspirin at 100 mg/day indefinitely and clopidogrel 75 mg/day for at least one month.
The purpose of this study is to determine whether cholecalciferol supplementation in patients with chronic heart failure and low vitamin D levels improves: 1. performance at six minutes walking test 2. echocardiographic parameters 3. neurohormonal imbalance
A subset of patients recruited in the main MATRIX study will be randomized after intervention but before discharge to standard of care (the treating physician will decide which oral P2Y12 inhibitor will be added on top of aspirin) versus a customized approach based on an algorithm which integrates phenotypic information, including but not limited to residual on-treatment platelet reactivity assessed via VerifyNow P2Y12 Assay.
This study is a randomized open label study that implies the administration of asprin according to three different regimens. The aims of the study are: - to establish whether coronary artery bypass surgery and / or aortic valve replacement surgery with bioprostheses is associated with changes in the rate of platelet regeneration that can reduce the effectiveness of aspirin administered at a dose of 100mg/die in terms of inhibition of platelet biosynthesis of thromboxane A2. - to determine whether these patients need a different (shorter) interval of administration in order to completely and permanently inhibit the platelet COX-1. The endpoints of this study are: - To evaluate the changes in the levels of TXB2 and 12-HETE in serum at 12 and 24 hours after administration of aspirin and the changes in the levels of 11-dehydro TXB2 urinary 8-iso-PGF2 alpha urinary, 2-3 dinor-6-chetoPGF1 alpha, Verify-NOW Aspirin, platelets crosslinked at 12 and 24 hours after administration of aspirin
Heart failure patients may benefit from having a special pacemaker implanted that can make the heart pump in a more coordinated and efficient way Cardiac Resynchronisation Therapy (CRT). For the heart to pump well it is necessary for the pacing wires to be placed in optimal positions. Only two thirds of people respond to CRT and this may be because of non-ideal pacing wire position. A potential marker for response is the change in heart pump pressure change over time. The aim of this study is to use a specialised wire in the main pumping chamber of the heart to record the pressure changes with the pacing lead in various positions to determine the optimal position. It is postulated that the improved pressure changes will increase the proportion of responders. Pilot study work has shown that the work is technically feasible and safe. The initial data has been published in a highly regarded scientific journal. This main study will be a multicentre randomised controlled trial whereby patients will be randomised to either standard treatment or pressure wireguided treatment. The patients in the pressurewire guided arm will have a specialised wire implanted into the main pumping chamber of their heart via a blood vessel at the top of the leg (or less commonly a blood vessel in the wrist). This will measure acute pressure changes over time and the pacing lead will be positioned in the site that gives the greatest change in pressure. If the patients in the pressurewire guided arm fare better than those receiving standard treatment it may alter how a large proportion of heart failure patients are treated around the world. The study requires 282 patients and is likely to take two years to complete.
The goal of primary PCI is to restore anterograde myocardial flow. Stenting a largely thrombotic lesion may determine distal embolisation of thrombotic material therefore deteriorating myocardial perfusion.
