Can pericardial effusion lead to myocardial infarction or any other serious consequence?

Q: I am seeking to find out if pericardial effusion resulting from a viral infection can lead to myocardial infarction and/or any other serious consequence?

A: if left untreated it can lead to cardiac tamponade, which is compression of the heart due to a large increase of fluid in the pericardium. this condition is life-threatening as it prevents the heart from pumping effectively.

How fast does nitroglycerin act when used to treat a myocardial infarction, i.e. when given in tablet form?

Q: I have been trying to find information online about the speed and efficacy of nitroglycerin in tablet form when used to treat a myocardial infarction. It’s for a short story I am writing, and I can’t finish until I find this information. I don’t want to just make something up.

A: Nitroglycerin doens’t actually do anything to treat a myocardial infarction. It is best for angina- the squeezing pain people get in their chest when the blood vessels around their heart are constricted but not completely closed. For angina, it works in seconds to relieve the pain and relax those blood vessels so the heart gets more blood. During a heart attack, the coronary vessels close completely, and blood flow to part of the heart is cut off. A person who takes nitroglycerin for angina should worry that they are having a heart attack if they take nitroglycerine and the pain does not go away. They should take an aspirin immediately and go to the ER to be given other meds or have a stent put in to open the artery back up.

what is the difference between a heart failure from myocardial infarction?

Q: can you have a heart failure without a myocardial infarction? or can you have a myocardial infarction without a heart failure? i’m really confused..

A: heart failure happens when the heart fails to pump adequate amounts of blood around the body… there are many reasons for this.myocardial infarction happens when an artery that feeds the heart muscle becomes obstructed, fails to deliver blood to the heart muscle itself and the muscle dies where it is lacking circulation.
