Active clinical trials for "Heart and Blood Diseases"

The program is to improve STEMI medical care quality in China. With the documents issued by National Health and Family Planning Commission of the People's Republic of China, the program was initialed in at least 200 primary PCI capable hospitals together with hundreds of adjacent non-primary PCI capable hospitals in 15 provinces. STEMI patients with symptom onset within 30 days will be enrolled in 3 periods. In each period with 6-month interval, 30 patients will be enrolled consecutively from each PCI-capable center initially and from non-primary PCI capable hospitals later, thus at least 18,000 STEMI patients from primary PCI capable hospitals will be enrolled and all of them will be followed up for 1 year. Key performance indicators (KPIs) in STEMI care will be collected using both national PCI online registry and a program STEMI online registry database for the purpose of improvement of medical care. Hospital KPIs rank report and problem-based resolution will be feedback to each hospital after data analysis in each period. Comparison of every two cross-sectional data (self) and within one cross-sectional (inter-hospital) data will be used to evaluate the improvement of medical quality.

The overall objective of the study is to determine whether speckle tracking echocardiography presents additional prognostic value to the routine assessment (clinical and echocardiographic) in patients admitted with acute decompensated heart failure (ADHF) at the emergency department. Specific objectives: 1 - To evaluate the association between changes in the cardiac contractile mechanics (by serial measurements of strain, strain rate, displacement velocity, rotation and ventricular torsion) with clinical outcomes in ADHF. 2 - Evaluate the possible association of these parameters with biomarkers of neurohormonal activity, myocardial injury, fibrosis and myocardial remodeling, inflammatory activity, and cardiorenal syndrome.

The emergency setting for acute neurological conditions, such as stroke, is peculiar due to time pressure and limited resources for further diagnostics. Clinical skills are essential for swift and accurate bedside diagnosis and thus are the basis for early and correct treatment. This is especially evident in the context of computed tomography being the standard neuroimaging method world-wide with its limitations for detecting smaller infarcts, strokes in the posterior fossa and reduced sensitivity for stroke mimics, such as epileptic seizures or migraine aura. To date, the accuracy of clinical bedside diagnosis of stroke by neurologists verified by magnetic resonance imaging (MRI) in the emergency setting has not been studied in detail. In order to improve clinical diagnosing and future treatment it is essential to quantify the accuracy of clinical diagnosis of stroke in the emergency setting ("how good are neurologists?") and to assesses whether there are any differences between experienced staff neurologists and junior physicians.

Patients hospitalized in internal wards are at risk for VTE. The current guidelines recommend the use of thromboprophylaxis for 7-10 days among patients who are at increased risk for VTE. Yet several retrospective studies have shown that the compliance with this guideline is low. Physicians are often reluctant to administer LMWH to their fragile patients mainly because they are not convince that the risk associated with such therapy is greater than the risk for VTE. In the current study, data concerning the use of thromboprophylaxis among patients admitted to the medical wards will be collected. The occurrence of bleeding or thrombotic event will be evaluated prospectively.

The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.

Patients with stroke were registered based on the WHO/ MONICA protocol and were followed-up for 28 days, starting in 2015 in PROVE Registry

the study will be carried out to standardize normal parameters of vascular duplex ultrasound of the cranial vessels in the Egyptian population.

The aim of the study is to investigate the ability to recall information given during informed consent on intravenous thrombolysis in patients with acute ischaemic stroke.

This study aims to compare whole-blood microarray gene-expression profiling between patients with acute myocardial infarction and normal participants without cardiovascular diseases. Firstly, screening differentially genes of mRNA to perform gene ontology and pathway analysis. Secondly, predicting target genes regulated by microRNA and constructing coexpression network with mRNA. Thirdly, biological function experiment of microRNA. Finally, revealing pathogenic mechanisms associated with acute myocardial infarction.

This is a registry study on a multidimensional prediction model for rupture risk of unruptured intracranial aneurysms in China.
