2. Tingling or numbness in the hands

A persistent tingling sensation or numbness in the hands may also be an early warning sign. Reduced blood circulation caused by heart problems can affect nerves and tissues in the extremities. If this sensation occurs frequently or without an obvious cause, it may be worth discussing with a healthcare professional.

3. Swelling in the legs or ankles

 

Fluid retention in the lower body is sometimes linked to heart function. When the heart struggles to pump blood effectively, fluid may accumulate in the legs, ankles, or feet. This swelling, known as edema, often becomes more noticeable by the end of the day or after long periods of standing or sitting.
