question: Doctor, My father( 60yrs old) got his health chek up done last month, where his ECG showed NORMAL LV SYSTOLIC FUNCTION LVEF. 60% DIASTOLIC DYSFUNCTION and a week ago he got his TMT done, which said NEGATIVE FOR INDUCIBLE ISCHEMIA AT GIVEN WORKLOAD . But today morning all of a sudden he felt pain( ranging between mild and severe) in the left side of the chest and weakness accompanied by sweating and numbness throughout his body. And he complains of left arm pain once in a while. He is not obese, not diabetic, does exercise and don t have any bad habits.
