<s>[INST] What Is the Difference Between Heart Failure, Heart Disease, and a Heart Attack? [/INST] Heart disease is an umbrella term for a lot of different conditions, such as:

Arrhythmia, or irregular heartbeat
Coronary artery disease, where plaque builds up in the vessels that carry blood throughout the muscles of the heart
Structural heart disease, where there’s a defect in the heart’s structure (valves, chambers, or walls)
Heart failure, when the heart is weak and unable to pump blood well; it hasn’t “failed’ or quit working, but it does need help to work better
Heart attack most often refers to a myocardial infarction (MI), where plaque buildup in the arteries keeps blood (and oxygen) from reaching the heart muscle. With better treatment today, more and more people survive their MI. Source: WEBMD. Link: https://www.webmd.com/heart-disease/heart-failure/answers-about-heart-failure. Field: Cardiovascular.
