Hi and thanks for the question,
Chest pain with a past history of heart disease
deserves an evaluation to exclude any cardiovascular origin. A simple chest X ray shall help in distinguishing a cardiac form a respitaory cause. Clinical evaluation shall o a big role in actually ascertaining whether you headache is actually a migraine headache
, measure your blood pressure to exclude any high blood pressure
and look for signs of heart failure
or other disease. Depending on this evaluation, a cardiac ultrasound and an electrocardiogramme to evaluate heart function and electrical activity could be of much help.
A good clinical examination and biological tests shall tell us whether is a pulmonary disease, a myocardial infarction
, microemboli or angina. Pulmonary causes shall also be ruled out.
I will suggest you book an appointment with your cardiologist for a proper physical examination and management.
'Thanks and best regards,
