Are the symptoms of a pulmonary embolism and a heart attack the same?

A pulmonary embolism can cause chest pain that feels like you're having a heart attack. The pain is often sharp and felt when you breathe in deeply. It can also stop you from being able to take a deep breath, and you may feel it when you cough, bend, or lean over. Chest pain when you're having a heart attack may feel more pressure-like and tends to radiate. Both conditions are life-threatening, so get emergency help if you have any symptoms.
