One hundred fifty patients with idiopathic hypertrophic subaortic stenosis
(IHSS) were followed-up for an average of 5.5 years. There were 95 males
and 55 females with a mean age of 51 years. Patients usually presented with
cardiac symptoms or syncope; no patient presented with stroke. Eight
patients (5%) died during follow-up, all from cardiac causes. Eleven
patients (7%) developed cerebrovascular complications; 5 (3%) had a stroke
and 6 (4%) had TIA only. Patients with IHSS and atrial fibrillation have a
much greater stroke risk. Mitral annulus calcification may also increase
stroke risk in IHSS. However, stroke is almost never the presenting
manifestation of IHSS, and the longterm risk of stroke for most patients
with known IHSS is low.
