Acute Myocardial Infarction : The Enduring Challenge for Cardiac Protection and Survival

概要

Although considerable advances have been made in the diagnosis and management of acute myocardial infarction (AMI), the disorder is still a major cause of morbidity and mortality worldwide and continues to pose significant therapeutic challenges. The use of biomarkers to aid the diagnosis of AMI is now increasing and has enabled better understanding of the pathophysiology of the disorder and identification of patients who require urgent reperfusion therapy. Early percutaneous coronary intervention (PCI) appears to be beneficial when performed in a timely manner with a door-to-balloon time <90 min. The goal of PCI is now shifting from simple revascularization of occluded coronary arteries to optimum reperfusion at the microvascular level. Effective strategies and pharmacological agents need to be developed for better cardiac protection during AMI. Most deaths resulting from AMI occur within 1 h of its onset, and half of them occur before hospital admission. Thus, an effective pre-hospital lifeline system should be an important priority, achieved through the chain of survival, including the immediate implementation of definitive resuscitative efforts and rapidly transporting the patients to the hospital.
