Heart attacks are serious medical emergencies that require immediate attention from a doctor. You could be at risk of a deadly heart attack – or myocardial infarction – if your fingernails start to curve downwards, over the top of your fingers, it’s been claimed.
Heart attacks are caused by a lack of blood reaching the heart.
Without enough blood, the heart could become seriously damaged – and it may even be life-threatening.
A heart attack could also be a symptom of coronary heart disease, which is where fatty deposits build up in the arteries, which limits the amount of blood reaching the heart.
Your fingernails may the first indicator that you’re at risk of a deadly heart attack.

“If you know what to look for, you can also find warning signs of heart disease on your skin and nails.
“Nails curve downward and the ends of your fingers are swollen – what it may be telling you: You may have a heart infection, heart disease, or lung problem.
“For many people, these signs are harmless. That said, if your fingers and nails look like this, it’s best to find out if you may have a medical condition, such as lung disease or a heart problem.”
