Insights
Individuals with neovascular age-related macular degeneration (AMD) experienced lower rates of myocardial infarction (MI) and cerebrovascular accidents (CVA). This study compared cardiovascular event incidence in neovascular AMD patients versus controls.
Area of Science:
- Ophthalmology
- Cardiology
- Epidemiology
Background:
- Neovascular age-related macular degeneration (AMD) is a leading cause of vision loss.
- Cardiovascular disease is a significant public health concern.
- The relationship between neovascular AMD and cardiovascular events requires further investigation.
Purpose of the Study:
- To compare the incidence of hospitalized myocardial infarctions (MIs) and cerebrovascular accidents (CVAs).
- To assess these cardiovascular outcomes in subjects with and without neovascular AMD.
Main Methods:
- Retrospective database cohort study.
- Involved subjects with neovascular AMD and matched controls.
- Analyzed healthcare claims data from 2002-2005 for MI and CVA events.
Main Results:
- Lower incidence rates of MI (16.2 vs. 23.1 per 1000) and CVA (14.3 vs. 22.1 per 1000) observed in neovascular AMD subjects.
- Adjusted rate ratios indicated significantly lower risk for MI (0.58) and CVA (0.56) in the neovascular AMD group.
- P-values < .001 for both outcomes, indicating statistical significance.
Conclusions:
- Neovascular AMD patients exhibited significantly lower rates of MI and CVA compared to controls.
- Findings were not attributable to systematic differences in case selection, healthcare utilization, or comorbidities.
- Potential for other unacknowledged biases exists.
Objective:
To compare the incidence rate of hospitalized myocardial infarctions (MIs) and cerebrovascular accidents (CVAs) in subjects with and without neovascular age-related macular degeneration (AMD).
Methods:
A retrospective database cohort study was performed in subjects with neovascular AMD and controls matched for age, sex, geography, and enrollment duration. Healthcare claims for the study period from January 1, 2002, to June 30, 2005, were used to identify subjects and outcomes. Incidence of hospitalized MI and CVA events and rate ratios adjusted for 11 risk factors were calculated.
Results:
In 7203 subjects with neovascular AMD and 20,208 controls, the rate of MI was 16.2 events per 1000 subjects with neovascular AMD and 23.1 events per 1000 controls. The adjusted rate ratio for MI was 0.58 (95% confidence interval, 0.48-0.72; P < .001) for subjects with neovascular AMD vs controls. The rate of CVA was 14.3 events per 1000 subjects with neovascular AMD and 22.1 events per 1000 controls. The adjusted rate ratio for CVA was 0.56 (95% confidence interval, 0.45-0.70; P < .001).
Conclusions:
Rates of MI or CVA were significantly lower in subjects with neovascular AMD than in controls. These findings could not be explained by systematic differences in case selection, health care use, or comorbidities, although other possible biases cannot be ruled out.
