  • Look Inside

Regional myocardial perfusion abnormalities com-monly occur during exercise in patients with hypertro-phic cardiomyopathy (HCM). Exercise 201Tl myocar-dial scintigraphy has provided a noninvasive means of identifying myocardial perfusion abnormalities in patients with HCM. On the other hand, apical hypertro-phic cardiomyopathy (APH) is reported as a subtype of HCM. Whether APH is essentially equal to HCM or not is controversial. To assess myocardial ischemia in patients with APH, we studied 28 patients with APH, with exercsie 201Tl SPECT.
