What is a heart attack?

 Extreme fatigue

Feeling tired all the time can be a symptom of heart failure, as well as of other conditions. Professor Newby says: “Many of my patients tell me they’re tired, whether they’ve got heart failure or not, whether they’ve got angina or not! It’s a difficult one, because it’s so non-specific.”If you’re tired and you’ve been working long hours or staying up late, it’s probably not your heart – but if you start experiencing extreme tiredness and your lifestyle hasn’t changed, it’s a good idea to chat to your GP.
