Filter by:In a prospective observational cohort study (n = 250) the investigators aim to assess the correlation between cardiac biomarkers, advanced echocardiography and HS severity and determine whether these are prognostic markers of heart disease in patients suffering from hidradenitis suppurativa (HS).
The objective of this study is to evaluate the effectiveness and safety of XIENCE Skypoint stents in comparison to other drug-eluting stents (DES) in real-world practice.
The study aims to assess the effect of smart watches and continuous glucose measuring devices on cardiovascular risk factors.
The registry study aims to discover biomarkers for accurate classification and risk assessment of ischemic heart disease.
This study is a multi-center, prospective, registry study. This research was supported by the National Key Research and Development Program. To establish a domestic multi-center, large-scale "brain-heart comorbidity" dynamic database platform including clinical, sample database, image and other multi-dimensional information requirements, through the construction of a multi-center intelligent scientific research integration platform based on artificial intelligence. Any of newly diagnosed cardiovascular related diseases were identified via ICD-10-CM codes: I21, I22, I24 (Ischaemic heart diseases) [i.e., ACS], I46 (cardiac arrest), I48 (Atrial fibrillation/flutter), I50 (Heart failure), I71 (Aortic disease), I60 (subarachnoid hemorrhage), I61 (intracerebral hemorrhage), I63 (Cerebral infarction), I65 (Occlusion and stenosis of precerebral arteries), I66 (Occlusion and stenosis of cerebral arteries), I67.1 (cerebral aneurysm), I67.5 (moyamoya diseases), Q28.2 (Arteriovenous malformation of cerebral vessels). The data is stored on the brain-heart comorbidity warehouse via a physical server at the institution's data centre or a virtual hosted appliance. The brain-heart comorbidity platform comprises of a series of these appliances connected into a multicenter network. This network can broadcast queries to each appliance. Results are subsequently collected and aggregated. Once the data is sent to the network, it is mapped to a standard and controlled set of clinical terminologies and undergoes a data quality assessment including 'data cleaning' that rejects records which do not meet the brain-heart comorbidity quality standards. The brain-heart comorbidity warehouse performs internal and extensive data quality assessment with every refresh based on conformance, completeness, and plausibility (http://10.100.101.65:30080/login).
Out-of-hospital cardiac arrest (OHCA) has multiple etiologies. In the absence of ST-elevation myocardial infarction, percutaneous coronary intervention (PCI) is delayed. This study aims to determine the diagnostic accuracy of Coronary Calcium Score (CCS) and Coronary CT Angiogram (CCTA) to rule out a coronary artery disease (CAD) in the first days after an OHCA.
Inflammation plays an important role in atherosclerosis and the occurrence of ischemic events. Statins, in addition to their lipid-lowering effect, have also documented anti-inflammatory effect that may partly explain their clinical benefit in reducing cardiovascular ischemic events. Colchicine is an orally administered anti-inflammatory drug that has been used for centuries in several anti-inflammatory or autoimmune diseases. Its mechanism of action occurs by the inhibition of tubulin polymerization and the generation of microtubules and by effects on cell adhesion molecules and inflammatory chemokines. However, there are no studies evaluating the in vivo "antiplatelet action" of colchicine in patients with established cardiovascular disease. We will evaluate the effect of low-dose 0.5 mg QD colchicine for 30 ± 3 days on platelet reactivity by MultiplateTRAP. Patients with proven chronic coronary artery disease, that is, documented previous myocardial infarction, will be randomized to receive colchicine 0.5 mg QD or placebo for a period of 30 ± 3 days.
Study design: A randomized controlled trial will be used, where patients will be randomized (1:1) to either the control group receiving usual care or the intervention group in which patients will receive usual care in combination with the TIMELY intervention for a duration of 6 months. Study sample: Female and male patients aged 18 years or over, with documented stable CAD and referred for cardiac rehabilitation (at > 2 weeks but <10 weeks after PCI or >4 weeks but <12 weeks after CABG or MI: STEM or non-STEMI), and/or having documented CAD by coronary angiography (stenosis in a major coronary artery >50%). Intervention: Patients randomized to the intervention group will receive the TIMELY app on their phones or tablets for 6 months. Patients will also receive a wearable activity tracker that collects activity levels, heart rate and sleep characteristics. Based on patient's activity levels, self-reported momentary mental states, health-related behaviors and environmental and clinical background factors, the app will enable patient-tailored recommendations relevant to improving lifestyle behaviors during daily life. In addition, patients will receive a blood pressure monitor that measures hemodynamic parameters through pulse wave analysis and an easy-to-use ECG device which will be used to assess changes in heart rate and other cardiovascular measures at rest and with exercise. Main study parameters/endpoints: The primary biomedical outcome is a change in the CoroPredict biomarker risk score from baseline (pre-randomization) to completion of the active intervention phase (6 months). The CoroPredict score is an indicator of the 10-year risk of mortality. The primary behavioral outcome is the change from baseline to 6 months in patients' functional status of fitness level (measured using the 6-minute walk test). The study further aims to improve secondary outcome measures: physical activity levels during daily life and cardiovascular responses to exercise, dietary habits, smoking behavior, medication adherence and perceived levels of psychological stress.

Clopidogrel monotherapy has been found effective in reducing ischaemic cardiovascular and haemorrhagic complications in patients with drug-eluting stent (DES) placement. However, concerns remain about the safety of long-term clopidogrel monotherapy in high-risk patients with HPR (high platelet reactivity) who do not respond adequately to clopidogrel. This study aims to evaluate the effectiveness of a patient-tailored antiplatelet therapy strategy that considers platelet aggregation in high-risk patients with DES placement beyond 12 months after stenting.
