  Purpose
In 2010, the sponsor conducted an observational study, entitled as "Nationwide Assessment of Cardiovascular Risk Factors: Blood Pressure, Blood Lipid, and Blood Glucose, in Chinese Patients with Type 2 Diabetes - 3B Study " which was to evaluate the level of cardiovascular diseases (CVD) risk factor control and its regional difference in China. As a continuation, this extension of the 3B Study is designed to assess the incidence of cardiovascular events, cardio-renal events, and other microvascular complications, in 1, 2 and 3 years in patients with type 2 diabetes and with high risk of (CVD) with or without existing or history of coronary artery diseases.

Further study details as provided by China Cardiometabolic Registries:

Primary Outcome Measures:
  • Incidence of CVD events [ Time Frame: 3 years ] [ Designated as safety issue: No ]

    The CVD event is defined as composite of :

    • Acute myocardial infarction
    • Stroke
    • Cardiovascular death


Secondary Outcome Measures:
  • Annual incidence of microvascular complications [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Estimated Enrollment: 5000
Study Start Date: March 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
with CAD
Patients with hypertension and dyslipidemia with prior CAD
without CAD
Patients with hypertension and dyslipidemia without prior CAD

Detailed Description:

Limited by its cross sectional design, 3B study was not be able to provide any information on how various patterns of treatment and prescribing behaviors would impact the outcomes of prevention of cardiovascular and cardio-renal diseases in type 2 diabetes longitudinally. This information, however, would be crucial in better guiding the real world medical practice and maximizing the effectiveness of medical treatment for better controlling cardiovascular risk factors.

The 3B Extension study is thus designed to extend the 3B study by continuing to follow up on enrolled patients for 3 years. The 3B Extension study is expected to demonstrate the clinical outcomes of nationally representative type 2 diabetes patients who are treated by endocrinologists, cardiologists and nephrologists separately in all tiers of hospitals, as measured by diabetes progression, incidence of cardiovascular complications, and incidence of microvascular complications. It will be the first study of this scale in China based on its exclusivity, extensiveness, and the level of government and national thought leaders' support. It will be conducted in collaboration with the advisory board of China Cardiometabolic Registries (CCMR).
