To prevent a heart attack, certain physical signs should not be ignored.

If you are suddenly running out of breath and there is no one around you to lend a helping hand, don't panic. Try to calm down. Sit where ever you are and take deep breaths, said Naikawadi and gave more tips to avoid a larger problem.

"If you are wearing any tight clothes, loosen them. Get your hands on an asprin tablet and make sure that you chew it well. It will work faster," she said.

"Make sure that you are not surrounded by a crowd that adds to the feeling of being restless. Drink something refreshing and if you are outside, look for a place with shade. If you feel it could be a heart attack, call for emergency medical help," Naikawadi added.

Naikawadi informed that according to a WHO report, four people die of heart attack every minute in India and the age group is mainly between 30-50.

A sudden heart attack is not uncommon, so it is advisable to check your family history and consult doctors. Under the scenario, regular checkups are must for everyone.

"However, the only way to find out about any such condition is to go for regular preventive health checkups starting early in life, especially individuals with a family history and high risk factors like obesity, high blood pressure and diabetes," Naikawadi advised.

A heart attack happens when the flow of oxygen-rich blood to the heart gets blocked. In such cases angioplasty, which costs around 2 lakh, could be the ideal remedy.

"Emergency angiogram is done and the blockage causing the heart attack is diagnosed. The blockage is removed and a stent is placed across the area," explained Karthik Vasudevan, Interventional cardiologist at Bangalore's Columbia Asia Referral Hospital.

To keep your heart strong after an attack, Singhal suggested strictly following a healthy diet and, regularly exercising without exerting and regular checkups.

Last but not least, do not ignore any chest pain.
