title: Physiological and anatomical bases for sex differences in pain and nausea as presenting symptoms of acute coronary syndromes.
abstract: Acute coronary syndromes (ACS) are common in both men and women. Studies show that women have longer times before diagnosis and treatment in the Emergency Department and worse outcomes than men, which may be related to the differing symptom presentations of men and women. Men are more likely to have chest pain, whereas women are more likely to have dyspnea or nausea. However, women tend to be older and more likely to have diabetes mellitus, hypertension, and peripheral neuropathies. Men and women also exhibit differences in the neural receptors and pathways involved in pain and noxious-stimuli perception. Moreover, men and women may have subtle differences in the locations and sites of their atherosclerotic lesions, all of which may affect symptom presentation. The purposes of this review are to present: (1) the physiology of two common symptoms associated with ACS, ie, pain and nausea; (2) how these symptoms differ between men and women; and (3) how different comorbidities may affect the presentation of these symptoms.
