When cardiac diagnostic exams have been first created, scientists on the time didn’t keep in mind that no two our bodies are alike, particularly between the sexes.

In keeping with College of Florida Affiliate Professor of Nursing Jennifer Dungan, many present symptom profiles and lab exams for coronary heart illness don’t precisely replicate the recognized variations in coronary heart illness in ladies. This oversight has elevated well being care fairness gaps.

“Because of this disparity, women are more likely than men to report symptoms of heart disease that appear outside the norm, experience delayed treatment for heart disease and even undiagnosed heart attacks,” Dungan mentioned. “For reasons that remain unconfirmed, women can experience heart disease differently than men. This can lead to inequality among women that needs to be addressed.”

The guts researchers imagine that a few of these variations in signs and outcomes could also be on account of genetic variations between women and men, Dungan mentioned. You have recognized a selected gene that you simply suppose may be accountable, known as RAP1GAP2.

“RAP1GAP2 is a strong candidate for sex-related effects on heart disease outcomes in women,” Dungan mentioned. “Some DNA markers in this gene are thought to manage the activity of platelets and the colorless blood cells that help blood clot. This also presents a risk of heart attack. An overactive gene can cause too many platelets to respond to clot, which can prevent clotting, which can prevent Blood and oxygen flow to the heart muscle and lead to a heart attack.”

As a result of RAP1GAP2 was not related to poor coronary heart outcomes among the many males in her staff’s examine, she thinks this gene may fit in a different way in ladies. Her staff included college members from the UF Colleges of Drugs, Pharmacy, Public Well being, and Well being Professions. Their findings have been lately printed in American Coronary heart Journal Plus.

Little is thought about these variations between races and races. Black ladies and a few Hispanic ladies are at the next danger of unhealthy coronary heart illness, on account of many elements that Dungan thinks might embrace genes.

Sadly, the normal methods by which racial and ethnic teams are studied have a tendency to provide irrelevant outcomes, Dungan mentioned.

“The goal is not to find biological differences between groups of people. Our goal is to find the most accurate genetic markers associated with heart disease for all women,” she mentioned. “And to do that, we need to look at genetic diversity within women as well.”

To find how the gene impacts coronary heart illness danger amongst ladies of various backgrounds, Dungan’s newest venture, supported by a two-year grant from the Nationwide Institute on Ageing, a division of the Nationwide Institutes of Well being, goals to seek out the precise RAP1GAP2 gene. Indicators which can be carefully associated to signs of illness, coronary heart assault, and loss of life in ladies of various racial and ethnic teams.

Utilizing well being knowledge from 17,000 postmenopausal ladies, Dungan and her staff will use statistical genetic strategies to investigate whether or not there may be an affiliation between sure DNA markers on RAP1GAP2 and coronary heart illness. Her staff will even use genetic ancestry markers as an alternative of arbitrary racial classes to account for the pure variety in our genetic code. In keeping with Dungan, this may verify that her staff is discovering genetic markers that replicate all coronary heart illness dangers in ladies, not simply sure teams.

“At the end of the study, if the RAP1GAP2 genetic markers accurately reflect a woman’s heart symptoms and predict her likelihood of having a heart attack, stroke, or death in the future, then these genetic markers can help us be more confident in diagnosing her and predicting the future,” he mentioned. “Having more accurate biomarkers for women would save lives and improve health equity for all women.”
