ABSTRACT
Coronary artery diseases [CAD] are leading causes of death in developed countries. Also, 10-15% of elderly people of the United State of America have gallstone. These two diseases have similar risk factors, such as obesity, elderliness, diabetes, hyperlipidemia, and hyper tension. Determining the correlation of coronary artery disease and gallstone is the main Aim of this study. This analytical cross-sectional study was done on 130 patients whom were suspected to CAD and have been referred to Shohadaye Kargar Hospital of Yazd echocardiography department. They have been randomly selected and echo test and sonography have been done for all by expert specialists. Data were analyzed by chi-square, Exact Fisher and Mantel-Haenszel tests. Stress test were negative in 80 [61.53%] and were positive in 50 [38.47%] patients. Of 80 negative stress test subjects, negative gallbladder sonography was observed in 77 [96.25%] patients; while in 3 [3.75] patients gallbladder sonography was positive. Among 50 positive stress test patients, 42 [84%] and 8 [16%] patients had negative and positive gallbladder sonography, respectively. There not found statistically significant association between CAD and gallston [p= 0.022]. Patients who had coronary artery disease, compared with healthy individuals, are at increased risk of gallstones. In men older than 50 years suffering from vague upper abdominal pain, Liver and gallbladder sonography ultrasound is recommended for detection of probable biliary stones
