Ventricular Arrythmia Clinical Trial
Official title:
China Structural Ventricular Arrhythmias Registry, a Multicenter,Observational and Prospective Study.
This is an observational, prospective, multi-center registry ,aiming at building a risk stratification for malignant structural ventricular arrhythmias. 2000 participants will be recruited from 10 centers in China,with clinical data to be abstracted from medical records ,and blood samples to be collected for finding promising risk indicators.The follow-up should be made every 6 mouths.
In China, the prevalence and risk factors of malignant ventricular arrhythmias remain
unclear. In addition ,the mainstream treatment relies on implantable devices and
medication.China Malignant Ventricular Arrhythmias Study is a nation-wide complex consisting
of several interrelated studies, with the aim of building a risk stratification as well as a
efficient and economic strategy for early prevention and treatment.
Structural Ventricular Arrhythmias Registry, as a part of China Malignant Ventricular
Arrhythmias Study, is an observational, prospective, multi-center registry, aiming at
building a risk stratification for malignant structural ventricular arrhythmias. 2000
patients with definitive diagnosis will be recruited consecutively from 10 major arrhythmia
centers distributed in 6 areas in China. At study entry, participants will be interviewed and
asked to sign the informed consent. Demographic characteristics, medical history, clinical
features, laboratory tests, imaging pictures, medications, procedures, and in-hospital
outcomes of patients will be abstracted from medical records by well trained staffs .At the
same time, blood samples will be collected to detect biological markers, like genes,
inflammatory factors ,etc. Once enrolled, the participants will receive follow up every 6
mouths about condition of arrhythmia, medication, clinical events, etc.
