BROOKLYN - National Wear Red Day was celebrated Friday to spread awareness about heart disease. 

Doctors at Brooklyn Hospital Center are warning people of the warning signs of an unhealthy heart. 

Shortness of breath, chest and shoulder pain or pressure, fatigue, and being easily worn out could be warning signs.

Doctors urge everyone to know their blood pressure, cholesterol and glucose levels, and get them checked annually. 

A nutritionist also recommends a controlled diet to prevent heart disease. 

Experts also advise to stay away from smoking and reduce alcohol, sodium, and caffeine intake. It is also important to exercise as much as possible.
