This study is based on the comparison between management versus PCI in patients with CAD. The prevalence of the major forms of cardiovascular disease (CVDs), mostly coronary artery disease (CAD), has changed dramatically in recent years. Cardiovascular disorders are now the one of the major cause of death and disability in the world.1 In 2015, 17.7 million individuals died from cardiovascular disease (CVD), which is around 31% of all deaths worldwide; 7.4 million pass away from coronary artery disease (CAD), and 6.7 million expired from stroke. 2 CAD is also the major cause of death, count for 13.2% of all deaths globally.3 It is responsible for one-quarter of all deaths in the United States of America (USA). About 75 percent of people with CAD in European countries are between the ages of 27 and 34.4 CAD was accountable for 16% of all man deaths and 10% of all female deaths in the England.5 Sudden death and CAD have a close connection. According to post-mortem reports and death certificates, 62-85 percent of patients who expired outside of the clinic have a past of CAD.6 As per informations from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2014, myocardial infraction affects 3.0% of the mature people in the USA (3.3 percent of males and 2.3 percent of females). An MI occurs every 40 seconds or so in the USA. In the USA, the mean age at 1st MI is 65.6 years for guys and 72.0 years for ladies.7 In this study the management and PCI are compared in patients with CVD.
