Hello and thanks for the query
At the age above 40 with a strong family history, you have every region to be investigated for chest pain
. So go to ER and do your EKG and test for heart enzymes, if possible can do stress test
or Tread mill test and Lipid profile
. If every thigh can back normal than need not to worry.
As per the pain in night is concern you have to check for a heart rate
to night or go for Holter study. May be reduced heart rate is causing the pain. But if you pain is associated with shortness of breath
, profused sweating and discomfort, it is surely be related to heart.
So go to ER and rule out any heart related issue.
