Insights
Elderly patients (over 70) with myocardial infarction face significantly higher mortality and complication rates. Active management tailored to age and physiological status is crucial for better outcomes in older adults experiencing heart attacks.
Area of Science:
- Cardiology
- Geriatric Medicine
- Internal Medicine
Background:
- Myocardial infarction (MI) management strategies require age-specific considerations.
- Elderly patients represent a significant and growing population experiencing MI.
Purpose of the Study:
- To compare outcomes of myocardial infarction in patients over 70 versus those under 70.
- To evaluate the effectiveness and safety of acute phase management strategies in elderly MI patients.
Main Methods:
- Retrospective analysis of 498 patients hospitalized for myocardial infarction over three years.
- Comparison of clinical characteristics, treatment interventions, and outcomes between elderly (>=70) and younger (<70) MI patients.
Main Results:
- Patients over 70 had higher hospital mortality (17.5% vs. 6.5%) and acute complication rates (60.8% vs. 23.7%).
- Elderly patients received thrombolysis and coronary arteriography less frequently.
- One-year survival was significantly lower in the elderly group (59.6% vs. 81%).
Conclusions:
- Myocardial infarction in the elderly is associated with substantially higher mortality and morbidity.
- Age-appropriate, active management during the acute phase is essential for improving outcomes in older MI patients.
Abstract:
Among 498 patients hospitalised for myocardial infarction during a three year period, 194 (39%) were aged over 70 (mean age: 78.6 +/- 6), including 99 women and 95 men. Comparison of this group of patients with those aged under 70 showed a significantly higher hospital mortality (17.5% v. 6.5%) (p < 0.01) and a higher acute complication rate (60.8% v. 23.7% (p < 0.01), in particular after the age of 75. Twenty-eight patients were treated by thrombolysis (14.4% v. 50.6%) (p < 0.05), with a 79.2% patency rate in follow-up angiography at 48 h, and only one non-fatal hemorrhagic complication. Eighty-six patients were investigated by coronary arteriography (44.9% v. 87.2% (p < 0.05) without any complication. Mean ejection fraction was 57.3 +/- 13.5%. Fifty patients were treated by angioplasty (24.6% v. 57%) (p < 0.01) including 15 during the acute phase, with primary success in 40 of them (80%). Ten patients underwent coronary bypass following their infarction (5.1% v. 6.25%) (NS) with two per- or postoperative deaths (20%). Follow-up study revealed high secondary mortality with an overall survival rate at one year of 59.6% v. 81% in patients aged under 70 (p < 0.01). In total, infarction in the elderly is characterised by high mortality and morbidity as compared with infarctions in patients aged under 70, and requires active management during the acute phase, assessed according to the physiological status and age of the patient.
