Effects of Cold Air on Cardiovascular Disease Risk Factors in Rat

Shuyu Snsam Zhang

The purpose of this study is to explore possible implicit counteraccusations of cold air in cardiovascular complaint (CVD) threat in rats. Healthy Wistar rats were exposed to artificial cold air under laboratory conditions, and their systolic blood pressure, heart rate, vasoconstriction, CVD threat factors, and myocardial damage pointers after cold air exposure were determined and estimated. Systolic blood pressure, whole blood density, and tube position of norepinephrine, angiotensinⅡ, low viscosity lipoprotein, total cholesterol, and fibrinogen in treatment groups increased significantly compared with control groups. No significant variations were set up in tube Mb and cTnT and myocardial towel between the treatment and control groups.
