I worked in a hot environment doing very heavy manual work. I went home after work and called my wife about 6 hrs later saying I felt I was having an anxiety attack. she suggested it might be due to the work and heat and gave me info on how to treat heat stress. later that evening appro 12hrs after work I had a heart attack (cardiovascular infarction) .I was rushed to emerg. where I was packed in ice and my body cooled to 32 deg c ....I had to have 3 stints in my heart due to blockages. did I have a heart attack due to heat stroke or are they non related
