[Clinical presentation of acute myocardial infarct in the elderly]
1Ziekenhuis Joannes de Deo, afd. Geriatrie, Haarlem.
Insights
Elderly individuals experience acute myocardial infarction (AMI) more frequently and with atypical symptoms like breathlessness. Older patients face significantly higher mortality rates from AMI compared to younger individuals.
Area of Science:
- Cardiology
- Geriatrics
- Epidemiology
Context:
- Analysis of 558 acute myocardial infarction (AMI) cases admitted between 1982-1985 in Haarlem-Noord.
- Focus on demographic and clinical differences between elderly (≥65 years) and younger AMI patients.
Purpose:
- To investigate age-related variations in AMI presentation, symptoms, and outcomes.
- To compare the incidence and mortality rates of AMI in elderly versus younger populations.
Summary:
- Elderly patients constituted 62.9% of AMI admissions, with an 8-fold higher incidence compared to younger individuals.
- Atypical symptoms such as breathlessness and heart failure were more prevalent in the elderly (4.5-30%) than classic precordial pain.
- Mortality rates were substantially higher in the elderly (31%) versus younger patients (7.7%).
Impact:
- Highlights the need for increased awareness of atypical AMI symptoms in geriatric populations.
- Informs clinical practice and public health strategies for managing AMI in older adults.
- Underscores the critical impact of age on AMI prognosis and survival.
Abstract:
From the district Haarlem-Noord, 558 patients suffering from an acute myocardial infarction (AMI) were admitted in the years 1982 through 1985. Of these patients 62.9% was 65 years or older, 63.6% was male. The chance of getting an AMI was 8 times greater for the elderly than for younger people, which is in agreement with figures in the whole country. The most important feature--precordial pain--was less frequent in the elderly, i.e. 63.8% compared to 87% for younger people. However, the elderly suffered more from less specific symptoms as breathlessness, heartfailure, dizziness, syncope, neurological and psychiatric symptoms. The frequency of these symptoms varied from 4.5 to 30%. This is 2 to 5 times higher than for people younger than 65 years old. The mortality rate was 31% for people older than 65 years. This was significantly higher than the rate for younger patients (7.7%).
