The most common sign of heart danger is chest discomfort. If you have a blocked artery or are having a heart attack, you may feel pain, tightness, or pressure in your chest, orthopaedic specialist Dr Sankalp Chaudhary tells WION.
Another symptom of a heart attack is that pain radiates down the left side of the body. It always starts from the chest and moves outward.
If you suddenly feel dizzy or shaky and also have chest discomfort or shortness of breath, it could mean that your blood pressure has dropped as your heart is not able to pump the way it should.
If you have pain or pressure in the centre of your chest which is spreading up to your throat or jaw, it could be a sign of a heart attack.
The unusually loud snoring that sounds like gasping or choking can be a sign of sleep apnea. It is when you stop breathing several times while you are still sleeping. This puts extra stress on your heart.
