Patients with hypertrophic cardiomyopathy frequently complain of chest pain during daily activities. ST-segment depression is described in association with sudden death and pacing, but its prevalence during ambulatory electrocardiographic monitoring is unknown. The aim of this study was to determine the relation of ambulatory ST-segment depression to clinical characteristics, risk factors for sudden death and thallium-201 perfusion in patients with hypertrophic cardiomyopathy. Continuous 48 h ambulatory electrocardiographic monitoring was performed in 113 patients (age 38 +/- 14 years) with hypertrophic cardiomyopathy. Ninety-four (83%) recordings were suitable for ST-segment analysis. A total of 109 episodes of ST-segment depression (> or = 1 mm from baseline) were recorded in 25 (27%) patients (mean 4 +/- 5). In patients < or = 30 years of age (but not > 30) there was an association between ST-segment depression and a history of exertional chest pain (seven of 12 vs one of 20; P = 0.001), and dyspnoea NYHA class II/III (seven of 15 vs one of 17; P = 0.008). There was no association between ST-segment depression and risk markers for sudden death, i.e. family history of sudden death, syncope and non-sustained ventricular tachycardia, in any group. Reversible thallium-201 defects occurred in 27 (29%) of the 94 patients with analysed recordings but were not associated with symptoms, risk factors for sudden death or ambulatory ST-segment depression. In young patients with hypertrophic cardiomyopathy, ischaemia-like ST-segment depression is common and is associated with a history of typical angina and dyspnoea. Reversible thallium-201 perfusion defects are associated with neither symptomatic status nor ambulatory ST-segment depression.
