the sudden cardiac pain followed by angioplasty and stenting in february last, changed my life altogether. i am now a timid soul. always depressed and apprehensive. i've been told that cardiac events may recur. so inspite of a negative tmt, normal ekg( moderate hypokinesis), normal lipid, strict diet and walking daily, i am now a shackled man. how do i fight this depression ? can i do any blood test say twice a year to be forewarned about an impending MI?
