3 weeks ago i had a heart attack (my 3rd attack ) durring the attack i was told the dr lost me 2 times and i had to be shocked. i also was medivacd to another hospital on a helicopter, my ? is , i was experiencing cold shivers , i was so cold i was shaking like someone in a freezer. my other attacks didnt do this , this is bothering me  maybe in a crazy way , but was this a symptom of heart attack , the drugs or was it just due to blood pressure being so low with them loosing me 2 times or was it due to me being so close to death?
Thanks for your question on Chat Doctor. I can understand your concern. Heart attack causes cardiogenic shock. And this causes hypotension. Hypotension triggers sympathetic stimulation and this causes tachycardia, perspiration, Shivering etc. With every heart attack, severity increases and chances of survival decreases. So you should be very careful in the future. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
