Millions of people are getting hospitalized due to chest pain. Well, what is chest pain? Or what is the cause of that chest pain? There are multiple conditions besides heart attack that can cause chest pain, from pancreatitis to pneumonia or panic attack. Chest pain could be as simple as a burning sensation due to acidity or complicated enough to be life-threatening. Chest pain could be because of a preexisting cardiac or non-cardiac condition. Most of the time, chest pain is associated with the cardiac condition such as Angina, a warning sign of a heart attack. People suffering from angina might have to undergo a procedure (revascularization). There are other causes such as a blood clot in the lungs (pulmonary embolism); or chest pain that occurs when the heart is not getting oxygen-rich blood during physical action or emotional stress.
A person can have a heart attack but might have different symptoms from another person. Some people feel sharp chest pain, while others might feel back pain or jaw pain; some can have symptoms like extreme fatigue or breathlessness.
