How EXACTLY does general anesthesia lead to heart attack, stroke or death? What are the mechanisms in the drug that leads to a stroke? How does it kil

No single answer: Serious complications from GA are much more likely in pts who are already sick. If you have coronary artery disease, the stress of surgery and anesthesia can lead to heart attack. If you have already had a stroke, the same stresses can contribute to another. No one drug or technique is at fault. Surgery makes the body tend to form clots as part of healing. This can add to risk of stroke or MI. ...Read more

Reduce pain: There is actually some debate about the use of nitroglycerine in the setting of all heart attacks. It is known that nitroglycerine dilates the veins and to a lesser extent the arteries and sort of "unloads" the heart. As such it will make it easier for the heart to pump under the stressful circumstances of a heart attack. However, when the blood pressure is low, it is not a good idea. ...Read more
