The relationship between clinical parameters and lifestyle variables among patients with severity of coronary artery stenosis: A cross‑sectional analysis based on the severity of coronary artery stenosis

Cardiovascular diseases are the leading cause of death all over the world. Lifestyle can have an important role not only in reducing risk factors but also in the prevention and treatment of coronary heart diseases. The aim of this study was to examine the relationship between clinical parameters and various aspects of patients’ lifestyles according to the severity of their coronary artery stenosis.

This study was a descriptive, analytic study carried out on 220 patients undergoing coronary angiography at Mazandaran Heart Center. Based on the angiography results, patients were divided into two groups: artery stenosis > 50% (110 cases) and < 50% (110). Patients’ lifestyles were evaluated using health‑promoting behavior questionnaire. Blood pressure and triglyceride, low‑density lipoprotein, high‑density lipoprotein, cholesterol, and fasting blood sugar were also measured. After collecting data, SPSS 21 software, Chi‑square test, t‑test, and multiple linear regression were used for analysis of the data.

The results showed that in patients with positive angiographic data, there is a significant correlation between clinical parameters and dimensions of health‑promoting behavior (P < 0.05).

Given the impact of clinical parameters on various aspects of lifestyle, it seems that by teaching the different aspects of lifestyle (such as having a healthy diet consisting of fresh fruits and vegetables, reducing intake of saturated fat, physical activity and regular exercise, stress management, and blood pressure control) to patients with a positive angiographic result, we can improve their lifestyles by means of improving clinical parameters.
