Why does mi cause nausea

Sex was a marginally important variable. After adjusting for sex, the presence of nausea or vomiting still predicted infarct size p less than 0. Thus, cardiogenic nausea and vomiting are associated with larger myocardial infarctions but do not suggest infarcts in a particular location.

Abstract Nausea and vomiting occurring during myocardial ischemia is believed to be associated with inferior wall infarction. Substances Creatine Kinase. Sixty-one percent of the patients with nausea or vomiting had an infarction. The likelihood of having an infarction was more than three times greater in patients with nausea and vomiting than in patients without these symptoms.

The peak creatine kinase level, an index of infarct size, was almost twice as high in patients with nausea or vomiting as it was in those without. Fifty-one percent of patients with inferior wall infarcts and 66 percent of patients with anterior wall infarcts had nausea or vomiting.

While nausea and vomiting did not predict infarct location, these symptoms were important predictors of serious disease. Nausea and vomiting during acute myocardial infarction and its relation to infarct size and location.
