Active clinical trials for "Heart and Blood Diseases"

The CAvEAT study is a not for profit, international, multicenter study aimed to assess the feasibility of selective coronary angiography (CA) after Transcatheter Aortic Valve Implantation (TAVI), to investigate predictors of successful selective cannulation (anatomical, technical, etc.) and to investigate if there is a significant difference among different type of transcatheter valves in selective coronary cannulation.

CTEPH-SOLUTION aims to create a risk score for the early detection of Chronic Thrombo-Embolic Pulmonary Hypertension (CTEPH) among patients with previous pulmonary embolism. The risk score, created on retrospective data, will be validated on newly diagnosed pulmonary embolism patients.

The investigators aimed to test the reliability and validity of the Chinese version of patient-completed CRS in hospitalized patients and to evaluate whether this form can be widely used in clinical practice instead of only health care workers' evaluation.

The aim of this study was to investigate the association between different reperfusion timing and ventricular arrhythmias (VAs) to provide evidence for clinical decision-making for patients with ST-segment elevation myocardial infarction (STEMI). All the participants included in the study were diagnosed with STEMI according to the 4th universal definition of myocardial infarction, with a follow-up of 1, 6, 12 months, respectively. Symptom onset-to-reperfusion timing (SO2RT) and 24h-dynamic electrocardiogram parameters were recorded to compare different SO2RT and VAs during 3 follow-up visits.

Intermittent or continuous proton pump inhibitor (PPI) therapy are recommended for high-risk bleeding ulcers according to the French Society of Gastroenterology. The prevalence of incidence of vein infusion phlebitis after PPI intravenous infusion is high in geriatric acute ward (about 10% of severe vein infusion phlebitis). The primary of objective of the study is to determinate the prevalence of vein infusion phlebitis after PPI intravenous infusion in aging people. The secondary of objective of the study if to determinate the factors of risk of vein infusion phlebitis.

Stroke ranks 3rd among disability-causing diseases worldwide. Following a stroke, loss of lower extremity motor function causes serious gait disturbances. The walking activity is the basis for daily and social engagement activities. Mobility (locomotion) ability; gait analysis can be evaluated with tests and reports examining walking performance. ABILOCO is also a questionnaire developed by Caty et al., evaluating mobility and locomotion in individuals after stroke. The aim of this study is; To investigate the validity and reliability of the Turkish version of the ABILOCO questionnaire developed to evaluate mobility in patients with stroke. The sample of the study will be literate individuals who have had a stroke who applied to the Neurology Unit of Ankara Hacettepe University Faculty of Physical Medicine and Rehabilitation. Demographic information of the cases will be recorded. ABILOCO questionnaire will be adapted to Turkish. The validity and reliability comparison of the ABILOCO questionnaire with the Berg Balance Scale and Timed Get Up and Go Test will be performed.

Upper limb impairment occurs in approximately 70 to 80 per cent of adults post stroke. These impairments will have consequences on functional performance in activities of daily living and hence quality of life. Assessment of upper limb function is a component of rehabilitation that contributes to the selection of optimal interventions according to patient individualized needs. The Arm Activity Measure (ArmA) provides a standardized assessment of upper limb passive and active perceived performance that is only available in it's English version. The aim of this study is to translate and conduct a cross-cultural adaptation of the ArmA is order to investigate its psychometric properties through a validation study among stroke patients.

Early diagnosis of NSTEMI and UA patients is mainly through the construction of machine learning model.

Anti-neutrophil cytoplasm antibodies (ANCA) are defined as important serological markers for the diagnosis of some forms of small vessel vasculitis, including granulomatosis with polyangiitis (GPA) , microscopic polyangiitis(MPA) and to a lesser extent Churg -Strauss syndrome or Eosinophilic granulomatosis with polyangiitis (EGPA).So they are called ANCA-associated vasculitis(AAV). An international consensus statement for ANCA testing statement was issued in 2017 and states that the antigen specific immunoassays can be used for the accurate diagnosis of ANCA-associated vasculitis without the need for indirect immunofluorescence(IIF). In the present study we will test whether the antigen specific assays screening is a valuable alternative to IIF confirming with immunoassay for the diagnosis of AAV on a number of patients and controls. Aim To evaluate the performance of the recommended strategy for the detection of ANCA based on screening with antigen specific immunoassays on a number of AAV patients and relevant disease controls In Kagawa university hospital (rheumatology department). Patients and methods This is a prospective study will be conducted at the department of rheumatology in Kagawa university hospital in which consecutive samples will be included from patients suspected to have AAV; patients subsequently identified as having AAV will be included as AAV patients, while patients in which the diagnosis AAV is rejected, will be included as disease controls. PR3-and MPO-ANCA will be performed using assays from Medical & Biological Laboratories Co (Anchor CLEIA) isayama.takuya@mbl.co.jp

--- Background and study aim Atrial fibrillation (AF) is an irregular heart rhythm which causes a five-fold increase in the risk of stroke. Approximately one in ten people aged over 70 have AF. If AF is recognised then the risk of stroke can be reduced by taking tablets regularly. AF can be difficult to recognise as it can occur without symptoms and only intermittently. Consequently, AF is not recognised in many people, meaning they live with an increased risk of stroke. Therefore, it is important to find ways to identify AF more reliably. Recently, wearable devices have been developed which could be useful for identifying AF. Several devices can monitor heart activity in daily life, including wristbands, smart watches and chest patch monitors. The aim of this study is to assess the acceptability and performance of wearables for use in AF screening in older adults. The primary objective is to determine the feasibility of measuring inter-beat-intervals using a wristband. The secondary objectives are: (i) to determine the acceptability of wearables; (ii) to determine the acceptability of the screening approach; (iii) to assess the performance of wearables for acquiring signals; (iv) to assess the performance of signal processing algorithms; and (v) to assess the performance of wearables for AF screening. --- Who can participate? Selected people who have previously participated in the SAFER Programme can participate in this study. The Investigators will invite previous SAFER Programme participants to also participate in this study, aiming to enrol 65 without AF, and 65 with AF. --- What does the study involve? Participants will be asked to wear three devices for seven days: Two wristbands (like watches), and one chest patch (like a plaster). These devices will collect measurements of their heart's activity. The Investigators will also ask participants to tell them how they found wearing the devices by completing a questionnaire. The Investigators will compare how participants found wearing each device, and how accurately each device identifies AF. --- What are the possible benefits and risks of participating? There will be no direct benefit to participants, although this research is intended to benefit future patients like them. Some participants may experience irritation or redness whilst wearing a chest patch - participants will be advised that if this occurs then they should remove it straightaway.
