Does myocardial blood flow and coronary vasodilator reserve differ between patients with syndrome X and normal controls?
Does myocardial blood flow and coronary vasodilator reserve differ between patients with syndrome X and normal controls?
The absence of differences in myocardial blood flow and coronary vasodilator reserve between syndrome X patients and controls casts doubt on ischemia as the primary cause of chest pain in these patients.
No takes yet. Share an insight, caveat, or question.
Challenges ischemic etiology of chest pain in syndrome X; leaves open nonischemic mechanisms for prospective study.
Rosen et al. (1994) studied this question.
