The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke, injury, or cardiac arrest due to heart attack.
In 2021, the American Heart Association clarified that "heart attack" is often mistakenly used to describe cardiac arrest. While a heart attack refers to death of heart muscle tissue as a result of blood supply loss, cardiac arrest is caused when the heart's electrical system malfunctions. Furthermore, the American Heart Association explains ...
Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.

The overall goal is to get your heart rate up, which may make you feel a little winded, but not gasping for air. “So, take a quick walk today, and make it a habit. Your heart will thank you ...
With the availability of treatments that can reduce stroke severity when given early, many now prefer alternative terminology, such as "brain attack" and "acute ischemic cerebrovascular syndrome" (modeled after heart attack and acute coronary syndrome, respectively), to reflect the urgency of stroke symptoms and the need to act swiftly.

In some cases coma can give the brain an opportunity to heal and regenerate, [34] but, in general, the longer a coma, the greater the likelihood that the person will remain in a vegetative state until death. [9] Even if the patient wakes up, brain damage is likely to be significant enough to prevent a return to normal functioning. [citation needed]
Keep up with your check-ups. In addition to following a heart-healthy diet and lifestyle, Dr. Belardo says that regular cardiovascular check-ups and discussions with healthcare providers about ...
