My husband died of an apparent heart attack two years ago.  He had been treated for bronchitis and asthma systems a week before, put on antibiotics and steroids.  Could pneumonia cause his heart to stop?  Two days after he died the clinic called to say they needed to see him right away.  Something showed up on his xray the week before.
Hello, Thanks for writing to Chat Doctor, I am Chat Doctor. Heart attack is a condition in which there is no blood supply to heart myocardium n lead to dying of heart muscles.risk factor for heart attack are age, gender(male >female), family history, DM,Smoking, HTN etc. ,but pneumonia do not case heart attack.but if patient already had heart disease than infection ca cause acute failure which may lead to death.if u can attach x-ray I can comment that what he saw on X-ray ....it can possible patient have heart attack n didn't note n his heart start facing like in patient old age, female,DM pain is not present called silent heart attack n this result patent don't know that he/she having condition n result heart functions goes down n if patent have infection this result in acute failure that can lead to death, n x-ray might showed enlarged heart sign of heart failure. I hope this answered your question, if you have more feel free to ask. Regards.
