Studies have proved there are three clues on the hand, which reveal the possibility of heart attacks. The first clue is said to be a yellow-orange rash on the fingers.
The rash indicates that the levels of triglycerides are too high and this may result in atherosclerosis.

The British Heart Association says high levels of triglycerides contribute to the risk of heart disease.

The second sign, according to studies, is the appearance of a dark spot under the nails.

The British Heart Foundation (BHF) says small spots of blood trapped under the nail could indicate an infection in the lining of the heart or valves, called endocarditis.

BHF explained that this inflammation occurs when the inner lining of the heart chambers and valves becomes infected, due to the entry of bacteria or fungi into the bloodstream, and stick to deformed heart valves or damaged heart tissue.

The third sign is the bluish or greyish colouration of fingers, due to lack of oxygen-rich blood in the circulatory system, due to the narrowing of the blood vessels.
