INTRODUCTION:  OSA exhibits a high prevalence, particularly among individuals possessing established risk factors and concurrent medical conditions. This study aims to elucidate the link between sleep apnea and coronary artery disease.

OBJECTIVES: To assess the effect of Obstructive sleep apnea in women with coronary artery disease. Also, to have a comparison with that of men with coronary artery disease.

METHODS: It is a case control study done in 122 patients with obstructive sleep apnoea.  Factors such as age, body mass index, physical activity, frequent junk food intake, presence of diabetes were assessed. 

RESULTS:   61 cases having coronary diseases (CAD) and 61 controls not having CAD were taken. With 95% confidence interval (with an upper level of 6.906 and lower level of 1.550), the odds ratio obtained is 3.272. So, there is statistically significant association between obstructive sleep apnea and coronary artery disease. At the same time, the study proves that the coexistence of OSA with CAD, exacerbates CAD. The study also shows that women with OSA are having increased risk of CAD compared to that of men.

CONCLUSION: There is statistical association between obstructive sleep apnea and coronary artery diseases where OSA have significant effect on the severity of CAD and vice-versa.  Women having OSA are at a higher risk of developing CAD than that of men.
