Ankle/arm blood pressure index: an insurance perspective
1Swiss Reinsurance Group, Westport Connecticut, USA.
Insights
The ankle-arm blood pressure index (AAI) helps classify cardiovascular risk in older adults. An AAI of 0.9 or less indicates a higher risk of heart disease and mortality.
Area of Science:
- Cardiology
- Vascular Medicine
- Geriatrics
Background:
- The ankle-arm blood pressure index (AAI) is increasingly recognized for its clinical utility.
- Assessing cardiovascular disease (CVD) risk in the elderly population is a critical public health concern.
Purpose of the Study:
- To evaluate the effectiveness of the ankle-arm blood pressure index (AAI) in refining cardiovascular risk stratification among elderly individuals.
- To determine the association between low AAI values and adverse cardiovascular outcomes.
Main Methods:
- Analysis of existing studies and clinical data focusing on the ankle-arm blood pressure index (AAI).
- Statistical adjustment for traditional cardiovascular risk factors and pre-existing cardiovascular disease.
Main Results:
- A reduced AAI, defined as 0.9 or less, is significantly associated with increased morbidity and mortality from coronary heart disease and total cardiovascular disease.
- This association remains robust even after accounting for established risk factors and diagnosed CVD.
- The ankle-arm blood pressure index (AAI) is becoming more prevalent in medical documentation.
Conclusions:
- The ankle-arm blood pressure index (AAI) serves as a valuable tool for enhancing cardiovascular risk assessment in the elderly.
- Underwriters, particularly those in the elderly market or in regions with limited routine testing, should be educated on the significance of AAI.
Abstract:
Recent studies conclude that the ankle/arm blood pressure index (AAI) is a useful clinical tool for refining cardiovascular risk classification in the elderly. A reduction in the AAI to 0.9 or less is associated with increased risk for both coronary heart disease and total cardiovascular disease morbidity and mortality, as well as all-cause mortality. This relationship persists after adjusting for traditional risk factors and known cardiovascular disease. AAI will appear more common in attending physician's statements, prompting a need to educate underwriters about this technology. AAI may be of particular interest to insurers dealing in the elderly market, to those with strong physician examiner systems, and in markets where blood or urine tests are not commonly used in underwriting.
