Acute myocardial infarction (AMI) is a major cause of morbidity and mortality. The almost exclusive cause of acute coronary syndromes (ACS), including unstable angina, AMI with or without ST-segment elevation, and sudden cardiac death is atherothrombosis. This book discusses risk factors, emergency management and long-term health outcomes of myocardial infarctions. Some of the topics discussed include MI and cardiogenic shock; risk of MI in the pathophysiology and treatment of prostatic diseases; albuminuria; essential roles of monocytes/macrophages in ACI; and management of unstable angina/non-ST segment MI.
