Can you get a heart attack from three cups of coffee?

While consuming a large amount of caffeine in a short period of time can lead to caffeine toxicity, it's highly unlikely that drinking three cups of coffee would directly cause a heart attack. However, some people may be more sensitive to caffeine and experience increased heart palpitations or anxiety, which could be mistaken for signs of a heart attack. It's always best to consult a healthcare professional if you have any concerns about your health or how caffeine affects you.
