In a consensus statement, the Canadian Cardiovascular Society defines four stages of acute atherothrombotic myocardial infarction based on tissue injury severity.
"The new classification will help differentiate heart attacks according to the stage of tissue damage and allow health care providers to estimate a patient's risk more precisely."
Heart attacks, or acute myocardial infarction (MI), are one of the leading causes of death worldwide. The newly released Canadian Cardiovascular Society Classification of Acute Myocardial Infarction (CCS-AMI) appearing in the Canadian Journal of Cardiology, published by Elsevier, presents a four-stage classification of heart attack based on heart muscle damage. This work by a group of noted experts has the potential to stratify risk more accurately in heart attack patients and lays the groundwork for development of new, injury-stage-specific and tissue pathology-based therapies.
The Canadian Cardiovascular Society released the world’s first classification of acute myocardial infarction (AMI), or heart attack, based on heart tissue damage research that was driven by two cardiovascular investigators at Indiana University School of Medicine and Northern Ontario School of Medicine.
