title: Ambulatory monitoring of the ST segment in diabetic men with and without peripheral neuropathy.
abstract: To assess whether myocardial ischaemia is more common in diabetic patients with neuropathy, 24-hour ambulatory monitoring of the ST segment was performed on 27 diabetic men without peripheral neuropathy and in 28 with neuropathy. The patients were matched for age 54 +/- 7 years (mean +/- SD) versus 54 +/- 7 years and for duration of diabetes (16 +/- 9 years versus 16 +/- 12 years). None had clinical evidence of heart disease. Episodes of ST segment depression were seen during ambulatory monitoring in 12 diabetics (22%) but were not more common in patients with peripheral neuropathy. Four of the 13 diabetics with autonomic neuropathy had ST depression during ambulatory monitoring. During a median follow-up period of 50 months, four patients developed clinical heart disease. Three of these patients had shown ST depression during ambulatory monitoring. ST depression during ambulatory monitoring is common in diabetic men without cardiac symptoms but is not related to the presence of peripheral neuropathy. Diabetics with ST depression during ambulatory monitoring are at increased risk of developing heart disease in subsequent years.
