Impact of a chest pain clinic on recurrency of symptoms and readmissions among patients early discharged from hospital after acute myocardial infarction was ruled out.
This paper evaluates the impact of an early revisit including symptom evaluation and an exercise electrocardiogram on recurrency of symptoms and readmissions during 1 year of follow-up among patients coming to hospital with chest pain or an initial suspicion of acute myocardial infarction (AMI) but in whom the suspicion was quickly ruled out. Patients below the age of 65 admitted to the emergency department (ED) at Sahlgrenska Hospital due to chest pain or other symptoms raising a suspicion of AMI who were either directly discharged from the ED or discharged within 1 day after having AMI ruled out. Patients were allocated to two groups: (1) patients being re-evaluated in a chest pain clinic less than a week after discharge from hospital (intervention group) and (2) patients handled routinely with no formalized follow-up (control group). The intervention group (n=484) and the control group (n=374) were comparable at baseline. During 1 year of follow-up, patients in the intervention group had a lower rate of readmissions to the ED than patients in the control group (17.4% versus 24.9%, p < 0.05) and a lower rate of rehospitalizations (15.9% versus 23.3%, p < 0.05). The proportion of patients being on sick leave at any time during the follow-up did not differ and neither did the recurrency of symptoms. The introduction of a chest pain clinic for patients early discharged from hospital after having AMI ruled out indicated beneficiency in terms of a lower rate of readmissions to the ED and a lower requirement of rehospitalizations. However, a methodological weakness in the randomization procedure suggest carefulness in interpretation.
