NCT02081235
Acute kidney injury (AKI) is a major complication after cardiac surgery and has been reported to be associated with adverse outcome. Previous studies have reported that the incidence of AKI in patients undergoing surgery for congenital heart disease is as high as 42% and AKI increase the patient mortality, intensive care unit stay and hospital stay. Previous studies have reported several risk factors for AKI after congenital heart surgery, however, perioperative variables including anesthesia-related factors have not been evaluated fully. Therefore, the investigators attempt to find out independent risk factors regarding perioperative variables.
NCT01019200
Psoriasis patients are known to be at increased risk for heart disease. This may be due to the increased prevalence of cardiovascular disease risk factors in this population, including high blood pressure, diabetes, obesity, and high cholesterol. Although cholesterol levels are known to be altered in psoriasis, most studies have used standard lipid profiles to measure cholesterol. These tests indirectly measure LDL (bad cholesterol) and become less accurate when triglyceride levels are high, as often see in individuals with psoriasis. We have designed a case-control study that uses a more specific and detailed cholesterol test to measure serum lipid levels in psoriasis patients, allowing for more accurate determination of LDL and better assessment of the lipid-contribution to cardiovascular risk. We will also measure other markers of inflammation that may contribute to cardiovascular disease.
NCT01781858
The course of both pulmonary embolism (PE) and one of its more relevant late complications, i.e. chronic thromboembolic pulmonary hypertension (CTEPH) is still substantially unknown. Recent evidence has shown that the incidence of CTEPH is higher than previously believed, but this has not been confirmed by other studies. A clear link between PE and CTEPH has been questioned by some experts. A great number of patients affected by PE persistently have residual chronic thromboembolic material the meaning of which is a matter of debate. The evidence sustaining a link between chronic residual PE and subsequent PE recurrences or CTEPH is insufficient. Thus, a nationwide, multicentre, prospective cohort study was designed with the following aims: 1. to ascertain the incidence of symptomatic CTEPH after a first episode of acute PE; 2. to ascertain the incidence of venous thromboembolic (VTE) recurrences after a first episode of acute PE; 3. to evaluate whether a relation exists between chronic residual PE and CTEPH 4. to evaluate whether a relation exists between chronic residual PE and VTE recurrences; 5. to evaluate whether a relation exists between persistent right ventricular dysfunction and CTEPH; 6. to evaluate whether a relation exists between persistent right ventricular dysfunction and PE recurrences. For each enrolling centre, consecutive outpatients or inpatients with an objectively diagnosed first acute PE episode are considered eligible.
