The RECording COurses of vasculaR Diseases registry (RECCORD registry) is an observational, prospective, multicentre, all-comers registry platform. In the initial phase, patients referred for endovascular revascularization of peripheral artery disease (PAD) of the lower limbs will be prospectively included and followed up for at least one year. At baseline, data on patients' demographic characteristics, comorbidities, previous peripheral interventions, medication, and clinical stage of PAD (Rutherford category), haemodynamic parameters, and procedural data including complications will be assessed. Major adverse cardiac and limb events will be recorded at planned (at six and 12 months) and at any unplanned visits.

Current guidelines recommend that patients with ACS undergoing stent implantation might be offered extended DAPT treatment for up to 30 months if necessary. Therefore, we designed a prospective, multicenter, randomized, placebo-controlled trial among ACS patients with high-risk on ischemic and bleeding who received a new generation of DES and received 9 to 12 months of DAPT, and evaluated whether clopidogrel monotherapy reduce the risk of bleeding compared with clopidogrel plus ASA in the following 9 months and achieved non-inferior outcomes in preventing ischemic risk.
Stroke has become the leading cause of death in China. It has been shown that intracranial artery stenosis (ICAS) plays a key role in Chinese stroke patients. Although most of stenotic diseases in intracranial arteries are atherosclerotic, a substantial number of other vascular diseases, such as dissection, arteritis, moyamoya disease, and reversible cerebral vasoconstriction syndrome (RCVS), can also lead to intracranial artery luminal narrowing. It is challenging to differentiate the etiologies of ICAS relying on measuring luminal narrowing by angiographical approaches. In addition, the progression of intracranial atherosclerotic disease (ICAD) has been demonstrated to be highly associated with the risk of ischemic cerebrovascular events. However, the influence factors for ICAD progression remains unclear. High-resolution magnetic resonance imaging (HR-MRI) has been widely used to assess ICAS diseases. The different etiologies of ICAS are differentiable by MR-MRI according to the features of location, shape, signal pattern, remodeling, and contrast enhancement. Investigators have proved that HR-MRI is a reproducible technique that may be reliably utilized to monitor the changes of ICAD during natural follow-up or medical treatment. The ICASMAP (Intracranial Artery Stenosis MR Imaging: Aetiology and Progression) is a prospective, cross-sectional, observational, and multicenter study. The objectives of ICASMAP are to determine: 1) the spectrum of etiology of ICAS in stroke patients; and 2) the influence factors for progression of ICAD. A total of 300 patients with symptomatic stenotic disease in intracranial arteries (stenosis range: 30%-99%) will be recruited within two weeks after symptom onset from 18 different hospitals across Beijing-Tianjin-Hebei region in China within 1 year. All the patients will undergo HR-MRI for intracranial arteries at baseline, one-year, and two-years. The clinical risk factors will be collected and blood draw will be conducted. The ICASMAP study may help to improve the precise diagnosis and intervention of ICAS and stroke prevention.
This study is designed to evaluate the efficacy, safety and tolerability of autologous bone marrow derived mesenchymal stem cells compared to placebo (sham operation) when administered via percutaneous coronary infusion to patients with ischemic heart disease, who are screened by D-SPECT and have pretreated with 3-month cardiac shock wave therapy.
To evaluate, in a controlled setting, the early safety and effectiveness of the Penumbra/Indigo aspiration thrombectomy Systems (San Francisco, California), and to define optimal technique for the use of these systems in patients with confirmed peripheral acute occlusions.
After PCI searching for target lesion ischemia with intracoronary ECG will be performed and if found it will be treated pharmacologically
The FLAG1 study will assess the diagnostic performance of biomarkers Glutathion S-Transferase-π (GST-π) and Peroxyredoxin 1 (PRDX1) to identify cerebral infarction of less than 4,5 hours in a population of patients with neurological deficiency of less than 12 hours.
This study evaluates the addition of remote ischemic preconditioning and postconditioning to standard myocardial protection protocol in patients submitted to off - pump coronary artery bypass grafting in a prospective, 1:1 randomized, double blind fashion. An interventional group will receive remote ischemic preconditioning 24-hours before OP-CABG, immediately before surgery and within 60 minutes following surgery by means of lower limb ischemia achieved by pressure cuff inflation, whereas control group will receive sham procedure perioperatively.
The study is to investigate the feasibility and safety of autologous umbilical cord blood transfusion to treat the newborn infants with presence of clinical indications of neonatal hypoxic-ischemia encephalopathy (HIE) and anemia. Umbilical cord blood (UCB) is collected following labor and is transfused intravenously within 48 hours after the birth. Newborn infant without UCB available recieves the standard care will be enrolled as control group. Following the autologous UCB transfusion in the study group or standard care in the control group, HIE subjects will be followed for 2 years for survival and neurodevelopmental outcomes and anemia subjects will be followed for 6 months to assess the survival and change of hematocrit and hemoglobin levels.
