Diabetes Complications and the Risk of Cardiovascular and Cerebrovascular Diseases

Study Overview
=================
Brief Summary
-----------------
This study is intended to include 3000 diabetic patients in our hospital to collect complete medical history data, comprehensively improve the screening of diabetic complications and cardiovascular and cerebrovascular risk assessment.

Detailed Description
-----------------
With the economic development and lifestyle change, the incidence and prevalence of diabetes are increasing year by year in both China and the world. Diabetics are associated with a significantly increased risk of cardiovascular and cerebrovascular disease. It is a cross-sectional study. This study intended to include about 3000 adult patients with previously diagnosed diabetes mellitus, then collect their anthropometric data (age, gender, weight, height, waist circumference, hip circumference and etc.), life history (diet, exercise, smoking, drinking and etc.), medical history, familial medical history, clinical testing results about their diabetes complication, and make a comprehensive assessment of their cardiovascular and cerebrovascular risks. These data will be used to make further research about the diabetes complication and cardiovascular and cerebrovascular disease.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Framingham Risk Scose | The Framingham risk score calculates an individual's risk of coronary heart disease over the next 10 years based on cholesterol levels and non-cholesterol factors. Non-cholesterol factors are subdivided into risk factors, major risk factors, and other factors. Risk factors include: diabetes; evidence of coronary heart disease; evidence of atherosclerosis outside the heart. Major risk factors include: male older than 45 years old, female older than 55 years old; Smoking; Hypertension (higehr than 140/90mmHg or being treated for hypertension); High-density lipoprotein lower than 40 mg/dl; First-degree relatives, male younger than 55 years old, or female younger than 65 years old, with a history of coronary heart disease. A higher score corresponds to a higher 10-year risk of developing cardiovascular disease. | 1 week | 
| UK Prospective Diabetes Study risk score | This scale provides an estimate of the risks for a new coronary heart disease(CHD) event and stroke (fatal and nonfatal). The data used to calculate the UK Prospective Diabetes Study(UKPDS) risk scores (available at http://www.dtu.ox.ac.uk/riskengine/download.php) included HbA1c, systolic blood pressure, serum total cholesterol and HDL-C, atrial fibrillation, sex, age, ethnicity, smoking status, and diabetes duration. The risks of CHD, fatal CHD, stroke, and fatal stroke were estimated for 10 years. A higher score corresponds to a higher 10-year risk of developing cardiovascular disease. | 1 week |
