Atherosclerosis was associated with paradoxical coronary constriction during mental stress; leaves open its contribution to ischemia or need for targeted interventions.
Does atherosclerosis influence the vasomotor response of coronary arteries to mental stress?
Atherosclerosis disturbs the normal vasomotor response to mental stress, causing paradoxical constriction particularly at points of stenosis, likely due to endothelial dysfunction.
Yeung et al. (1991) studied this question.
