Evaluation of Normal Response in Angiography and Echocardiography of Coronary Artery Disease (CAD) Patients Hospitalized in Selected Hospitals of Yazd in the Second Half of 2014

Coronary artery disease (CAD) is the Non-contagious leading cause of mortality worldwide, as more than 1 million heart attacks and strokes occur every year, of which about 30% of them die. The use of invasive methods such as angiography for the diagnosis of coronary artery disease has been reached with high costs due to the cost of this method and its complications, and on the other hand, non-invasive methods such as echocardiography is more cost-effective and has fewer side effects.

This descriptive retrospective cross-sectional study was performed in selected hospitals in Yazd in the second six months of 2014. All cases were collected from patients admitted for angiography and echocardiography, and in total 1801 records/files were submitted for examination.

Assessment of patient’s records indicated, the echocardiography results in 38% of patients and exercise test results in 30% of the patients and the result of the angiography in 72% of patients, were abnormal .

The results showed that, 38% of the echocardiographic results and 72% of the angiographic results were abnormal. Performing non-invasive tests, such as echocardiography and exercise testing, resulted in a loss of cost due to a small number of positive cases and also may cause an anxious in patients. This result has been shown more likely in women and young individuals.
