Coronary artery disease is a cardiovascular disease and includes stable angina, myocardial infarction, unstable angina and cardiac death. A common symptom of coronary artery disease is pain in the chest that extends to the arm, back, shoulder or jaw. Shortness of breath, and a feeling of heartburn may also occur. The diagnosis of coronary artery disease is aided by electrocardiogram, coronary computed tomographic angiography, cardiac stress testing and coronary angiogram. Medications such as antiplatelets, nitroglycerin or beta blockers are recommended, while procedures such as coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) may be performed on a critical patient. In case of acute coronary syndrome, revascularization may be done. This book is a compilation of chapters that discuss the most vital concepts and emerging trends related to coronary artery disease. The various advancements in the diagnosis and surgical management of coronary artery disease are glanced at and their implications and ramifications are looked at in detail. It includes contributions of experts and scientists, which will provide innovative insights into this domain of medical science.
