[Pathological characteristics of coronary artery disease in elderly patients aged 80 years and over]
Insights
Coronary artery disease (CAD) is highly prevalent and frequently misdiagnosed in patients over 80. Old myocardial infarction (OMI) is common but often missed, necessitating improved diagnosis and evaluation in this elderly group.
Area of Science:
- Cardiology
- Geriatric Medicine
- Pathology
Background:
- Coronary artery disease (CAD) poses a significant health challenge, particularly in the elderly population.
- Accurate diagnosis of CAD, including old myocardial infarction (OMI) and chronic myocardial ischemia, is crucial for effective patient management.
Purpose of the Study:
- To define pathological changes in coronary arteries of individuals aged 80 and over.
- To compare clinical and pathological diagnoses of CAD in elderly patients (80+) versus younger elderly patients (60-79).
Main Methods:
- Analysis of 909 autopsy cases aged 60-100 years.
- Comparison of CAD prevalence and pathological features between the 80+ group and the 60-79 group.
- Calculation of misdiagnosis and missed diagnosis rates for CAD, OMI, and acute myocardial infarction (AMI).
Main Results:
- The 80+ group showed significantly higher prevalence of CAD (63.8% vs. 39.9%), OMI (63.0% vs. 51.6%), and chronic myocardial ischemia (22.5% vs. 7.1%) compared to the 60-79 group.
- The prevalence of AMI was significantly lower in the 80+ group (22.1% vs. 42.9%).
- High rates of misdiagnosis (65.2%) and missed diagnosis for OMI (62.1%) and AMI (37.5%) were observed in the 80+ group.
Conclusions:
- Coronary artery disease is highly prevalent in deceased inpatients aged 80 and over, with substantial rates of misdiagnosis and missed diagnoses.
- Old myocardial infarction is more common in this age group but frequently overlooked.
- Enhanced diagnostic strategies and evaluations for CAD are essential in elderly patients aged 80 and above.
Objective:
To define the pathological changes of coronary artery and compare the clinical diagnosis and pathological diagnosis differences in elderly patients aged 80 and over.
Methods:
A total of 909 autopsy cases aged 60-100 years in our hospital from April 1st 1969 to October 31th 2013 were analyzed. The prevalence and pathological features of coronary artery disease (CAD) in cases aged 80 years and over were compared with those aged 60-79 years old. The misdiagnosis and missed diagnosis rate were calculated.
Results:
The prevalence of CAD by autopsy (63.8% (289/453) vs. 39.9% (182/456), P<0.01), old myocardial infarction (OMI) by autopsy (63.0% (182/289) vs. 51.6% (94/182), P<0.05) and chronic myocardial ischemia by autopsy (22.5% (65/289) vs. 7.1% (13/182), P<0.01) were significantly higher while the prevalence of acute myocardial infarction (AMI) by autopsy was significantly lower (22.1% (64/289) vs. 42.9% (78/182), P<0.01) in aged 80 and over group compared to 60-79 years old group. The misdiagnosis rate of CAD was 65.2% (107/164), the missed diagnosis rate of OMI was 62.1% (113/182) and the missed diagnosis rate of AMI was 37.5% (24/64) in the aged 80 and over group.
Conclusions:
The prevalence of CAD and misdiagnosis and missed diagnosis rate are high in dead inpatients aged 80 years and over. OMI is more common but often missed in this group. Thus, the diagnosis and evaluation of CAD should be enhanced in this patient group.
