On October 28, 2023, the Canadian Cardiovascular Society Classification of Acute Myocardial Infarction (CCS-AMI)<\/a> – a new, never-before released classification of four stages of heart attack \u2013 was published in the Canadian Journal of Cardiology. A presentation<\/a> at the Vascular 2023 conference in Montr\u00e9al followed on October 29.<\/p>\n\n\n\n

This is the first heart attack classification of its kind to be released within Canada and internationally. The classification will help physicians and cardiac health care providers better estimate and predict a patient\u2019s risk of developing heart failure, arrhythmia, or dying. It will also open new avenues of research for more precise and individualized therapies to address the underlying damage at each heart attack stage.<\/p>\n\n\n\n

What is acute myocardial infarction (MI)?<\/strong><\/p>\n\n\n\n

An acute myocardial infarction is also known as a heart attack. A heart attack occurs when blood flow to the heart muscle decreases or stops, and the heart muscle begins to die because it isn\u2019t receiving enough oxygen. A heart attack is a medical emergency that requires immediate intervention from a healthcare provider to prevent permanent heart damage and death.<\/p>\n\n\n\n

How are MIs categorized currently?<\/strong><\/p>\n\n\n\n

Existing tools classify MIs using a patient\u2019s clinical presentation and\/or the cause of the heart attack, as well as ECG findings. Although these tools are very helpful to guide treatment, they do not consider the underlying tissue damage caused by the heart attack.<\/p>\n\n\n\n

What is the CCS Classification of Acute Myocardial Infarction (CCS-AMI)<\/a>?<\/strong><\/p>\n\n\n\n

The CCS-AMI Classification describes damage to the heart muscle following an MI in four sequential and progressively severe stages. It is based on a strong body of evidence about the effect an MI has on the heart muscle.<\/p>\n\n\n\n

What are the four CCS-AMI stages?<\/strong><\/p>\n\n\n\n
