Artificial intelligence in cardiology

The American Heart Association’s first-ever scientific statement on artificial intelligence (A.I.) in cardiology explores how the technology may improve how doctors prevent, detect, and treat heart disease. For example, A.I. data from patch monitors may predict who will develop potentially serious heart rhythms. Applying A.I. tools to a single chest x-ray may predict a person’s risk of heart attack and other serious health problems.

Dizziness demystified

Vertigo is a symptom, not a condition. It can make people feel lightheaded, faint, unsteady, or like the room is spinning. Common conditions causing vertigo include benign paroxysmal positional vertigo, vestibular migraines, vestibular neuritis, and Ménière’s disease. People should see a doctor after a single vertigo episode to determine the cause. Depending on the cause, treatments might include medications, a canalith repositioning procedure, vestibular therapy, and cognitive behavioral therapy. Staying active, not sedentary, between episodes can help people with vertigo feel better.
