Risk Factors for Coronary Heart Diseases in a Subhigh Altitude Area

Objective To investigate the risk factor for coronary heart diseases of people living in a subhigh altitude area.

Methods Medical records of 386 coronary heart disease patients diagnosed by coronary arteriongraphy and clinical symptoms in June 2013 to Junuary 2016 were reviewed retrospectively. The age, gender, BMI, duration of disease, degree of education, hypertension, hyperlipidemia, family history of coronary heart diseases and diabetes, situation of activity, smoking, alcohol abuse and irrational diet of all patients were investigated by a questionnare.A backward iteration statistical method was used to investigate the influencing factors for coronary heart diseases. By means of the vascular aging of patients as the dependent variable to establish an ordinal logistic model, all factors were substituted into the model to examine the weight of each factor on the relationship with coronary heart diseases and to explore the relevant preventive measures.

Results The age, gender, BMI, hypertension, hyperlipidemia, family history of coronary heart disease and diabetes, smoking, alcohol abuse, irrational diet and the activity of these patients were finally selected and had significant explanatory power with the dependent variable. Age, BMI, hypertension, hyperlipidemia, family history of coronary heart disease and diabetes, smoking, alcohol abuse, irrational diet and vascular aging were positively correlated risk factors, but gender and activity were protective factors.

Conclusion Controlling the body weight of coronary heart disease patients, adjusting the irrational dietary condition, changing the smoking and drinking habits can effectively reduce the development of the disease and the possibility of causing death.
