Comparison of mobilization after two and nine days in uncomplicated myocardial infarction
Insights
Early mobilization and hospital discharge for uncomplicated myocardial infarction patients showed no significant differences in mortality or morbidity compared to delayed approaches. This study suggests similar outcomes for patients undergoing early versus late recovery protocols after heart attack.
Area of Science:
- Cardiology
- Clinical Medicine
- Health Outcomes Research
Background:
- Uncomplicated myocardial infarction (MI) management traditionally involves prolonged hospitalization.
- Early mobilization and discharge protocols may offer benefits but require careful evaluation for safety and efficacy.
Purpose of the Study:
- To compare the clinical outcomes of early versus late mobilization and hospital discharge in patients with uncomplicated myocardial infarction.
- To assess the impact of different discharge timings on patient morbidity and mortality.
Main Methods:
- A randomized controlled trial involving 189 patients with uncomplicated MI.
- Patients were assigned to either immediate mobilization and 9-day discharge or delayed mobilization and 16-day discharge.
- Outcomes including mortality, recurrent chest pain, heart failure, dysrhythmia, and venous thromboembolism were monitored for six weeks post-admission.
Main Results:
- No significant differences were observed between the early and late mobilization/discharge groups.
- Incidence of recurrent chest pain, myocardial infarction, heart failure, dysrhythmia, and venous thromboembolism did not differ significantly.
- Clinical and (125)I-labelled fibrinogen scanning assessments showed comparable morbidity and mortality rates.
Conclusions:
- Early mobilization and hospital discharge are safe and effective strategies for patients with uncomplicated myocardial infarction.
- Delayed mobilization and discharge do not confer additional benefits regarding mortality or morbidity in this patient population.
Abstract:
A total of 189 patients with uncomplicated myocardial infarction were selected at random for early or late mobilization and discharge from hospital. Patients were admitted to the study after 48 hours in a coronary care unit if they were free of pain and showed no evidence of heart failure or significant dysrhythmia. Randomization was achieved by monthly cross-over of the three medical wards to which the patients were discharged. One group of patients was mobilized immediately and discharged home after a total of nine days in hospital, and the second group was mobilized on the ninth day and discharged on the 16th day. Out-patient assessment was carried out six weeks after admission. No significant differences were observed between the groups in terms of mortality or morbidity, as reflected by the incidence of recurrent chest pain or myocardial infarction, heart failure, dysrhythmia, or venous thromboembolism detected either clinically or by (125)I-labelled fibrinogen scanning.
