I Had A Heart Attack One Year Ago. In July

I had a heart attack one year ago. in July 2015 I started smelling a "chemical" odor and I still do, most days. The odor is sickening and I have to wear a face "painters type" mask at times. There are few days when this odor isn't present. I take 10 prescriptions, several of which are for anxiety and high blood pressure. Could the odor be connected to my heart condition?
