Introduction

Although hospital discharge rates for acute myocardial infarction are falling,1-4 no contemporary studies compare temporal trends in these rates for angina and other types of chest pain. We examined recent trends in population discharge rates for myocardial infarction, angina, and chest pain ("suspected acute coronary syndromes") between 1990 and 2000.

Participants, methods, and results

We got data from the Scottish morbidity record for Scottish residents aged at least 18 years with a "first" emergency hospitalisation for myocardial infarction (codes ICD-9 (international classification of diseases, ninth revision) 410, ICD-10 I21 or I22), angina (ICD-9 411 or 413; ICD-10 I20 or I24.9) or "other chest pain" (ICD-9 786.5; ICD-10 R07), between 1990 and 2000.5 We analysed discharges coded only in the principal position. A "first" hospitalisation was one with no discharge diagnosis of coronary heart disease or chest pain in the previous 10 years.

We calculated rates using annual official age and sex specific population estimates . . . [Full text of this article]
