21 hours ago This chapter illustrates various general issues in genetic epidemiology in relation to coronary artery disease (CAD). This is a disease strongly influenced by environmental/lifestyle factors, such as smoking, but with substantial estimated heritability. Researchers aiming to identify susceptibility genes have used several different definitions of CAD, some focusing on the … >> Go To The Portal

Diagnosing Ischemic Heart Disease Most of the time, we can diagnose the condition based on physical exam and imaging tests. In rare cases, we may need to perform a biopsy, a surgical procedure to remove some heart tissue, in order to rule out certain diseases.
