Abstract: The objective was to investigate the effects of cardiovascular risk factors on different type of severe acute respiratory syndrome(SARS)and the patient's prognosis.Altogether 219 patients with severe acute respiratory syndrome were divided into three groups mild,severe and critically severe.The risk factors included age,gender,history of diabetes,hypertension,coronary artery disease,cerebrovascular disease and hypertriglyceridemia,elevated total cholesterol as well as high uric acid.These factors were estimated in different groups or types of patients with SARS.Results:More severe and critically severe cases were found in the groups of patients aged above sixty.In patients with history of hypertension,diabetes and coronary artery disease,severe and critically severe types were much more than other patients.In patients of severe and critically severe types,the level of blood glucose and systolic blood pressure were higher than patients with mild conditions.The level of uric acid in most severe patients was lower than mild patients.Gender,the level of total cholesterol and triglyceride didn't influence the conditions and prognosis of patients.Some cardiovascular risk factors such as age,hypertension and hyperglycosemia can affect patient's conditions and prognosis.Other risk factors such as gender,value of total cholesterol and triglyceride can't influence these significantly.

Key words: severe acute respiratory syndrome, type, cardiovascular risk factors
