Adding hypertension in pregnancy doesn’t refine ASCVD risk prediction tool

 

Key clinical point: The ACC/AHA Atherosclerotic Cardiovascular Disease Risk Calculator doesn’t do a better job of predicting 10-year risk in women when a history of hypertensive disorders of pregnancy is added into the formula.

Major finding: Incorporating a woman’s history of hypertensive disorders of pregnancy into the Atherosclerotic Cardiovascular Disease Risk Calculator doesn’t improve the tool’s accuracy in predicting 10-year risk.

Study details: An analysis of data from the longitudinal, prospective Nurses’ Health Study II.

Disclosures: The study presenter reported having no financial conflicts of interest.

REPORTING FROM THE AHA SCIENTIFIC SESSIONS


She put the souped-up risk prediction model to the test by separately applying it and the current version to data from the longitudinal prospective Nurses’ Health Study II. For this analysis, nearly 68,000 female registered nurses were followed for new diseases every 2 years from 1989, when they were aged 25-42, through 2013. She and her coinvestigators applied the two 10-year risk-prediction models to the overall cohort and again separately to women at aged 40-49 and 50-59.

The bottom line: Including hypertensive disorders of pregnancy and parity did not improve the risk prediction model’s discrimination or reclassification capabilities. This might be because the nurses comprise a relatively low-risk population. Also, even though hypertensive disorders of pregnancy are associated with 10-year cardiovascular disease risk independent of the established risk factors, there may be enough overlap that the standard risk factors sufficiently capture the risk.

“It may be that the information on history of hypertensive disorders of pregnancy should be ascertained in the 20s and 30s, rather than waiting until age 40 or later, when we generally apply cardiovascular risk scores in practice. That [earlier assessment] may be a really important and valuable opportunity to identify these women at high risk and utilize primary prevention,” according to Dr. Stuart.

What’s next? “I’m certainly interested in educating these women about their increased risk. This is not something that’s done consistently across the country and across practices, and we really believe this is an important message for women to get when they deliver these pregnancies,” she added.

Dr. Stuart reported having no financial conflicts of interest regarding her study.
