I went through the same thing years ago .. could not get dr's to listen something was wrong just kept fluffing it off. Age ... weight ..lack of exercise ... etc ...etc .. After 2 years of me telling them something was wrong they did a 2nd heart cath, found I was 95% blocked on top and 100% blocked on the bottom. Had gone on for so long it damaged my heart. I was disabled unable to work from that moment on at age 45. Since then I have had 11 heart caths altogether and 5 hearts stents. 15 meds a day and 2 strokes I wonder what my outcome would have been if I could have gotten even one dr. to listen to me instead of fluffing me off.
