Screening Uncovers Hidden Cardiac Dangers in Young Women

Basic medical examinations are identifying young women with asymptomatic heart conditions that significantly increase their likelihood of sudden cardiac death (SCD), according to researchers in the United Kingdom. These insights are drawn from an analysis of a voluntary screening program, supported by a charity that assists grieving families, which has operated in the UK since the early 1990s.

The data reveals that among nearly 40,000 women aged 14 to 35 who underwent cardiac assessments, 175 were discovered to have undiagnosed heart issues, despite appearing robust and healthy. Of these individuals, 94 were classified as being at high risk for sudden cardiac death. Medical experts emphasize that SCD is not exclusive to athletic males; young women are also vulnerable, and early detection can be life-saving.

Consequently, the UK National Screening Committee is currently evaluating the feasibility of implementing mandatory checks for all individuals over the age of 14 regarding conditions linked to SCD. A public consultation is planned to address this proposal, though a specific date has not yet been set. The primary challenge lies in balancing the identification of genuine high-risk cases against the potential for inducing unnecessary anxiety among the youth through widespread testing.

Furthermore, standard screening tools, such as electrocardiograms (ECGs), are not infallible. In the most recent study focusing on girls and women, 92 heart issues went undetected, including 28 that were considered serious. Some causes of SCD are hereditary, and the National Health Service (NHS) provides free family screenings when such risks are suspected.

The human impact of these conditions is illustrated by the experience of Kaitlin Lawrence, a 24-year-old from Surrey. Two years ago, she was diagnosed with a heart rhythm disorder after collapsing on a netball court. She recalls feeling ill just before a league match, followed by a sudden loss of consciousness on the sideline.

"My teammates say they couldn't revive me and my lips were going blue, although I was still breathing," Lawrence said. "The next thing I knew I was in an ambulance on the way to hospital. I'm lucky I didn't die."

Lawrence now wears an implanted defibrillator, a device that has already intervened twice to save her life. She describes the mechanism as delivering an electric shock to reset the heart's rhythm, a sensation she compares to a "thump." "It feels like a thump when it happens. I had one recently, in February. It's a bit scary, but it works," she explained. She also takes beta-blocker medication to maintain a stable heart rhythm.

Lawrence believes her condition could have been identified early through a simple ECG. Her family has since undergone testing, and many of her friends have followed suit.

According to the charity CRY (Cardiac Risk in the Young), which facilitates voluntary screening, SCD claims the lives of approximately 12 young people under the age of 35 in the UK every week. The risk is roughly three times higher for boys and young men than for girls and young women. Often, victims display no symptoms and appear completely fit, with no visible warning signs.

CRY notes that minor physiological shocks, such as stepping into a cold shower or engaging in sports, can trigger fatal outcomes in individuals with undiagnosed cardiac anomalies. The charity suggests that the true prevalence of these conditions may be underreported, as some SCD cases are incorrectly attributed to asthma, epilepsy, or drowning. Post-mortem investigations frequently reveal inherited structural or electrical heart defects, although in one in 20 cases, no identifiable cause is found.

These findings, which span a decade of CRY’s voluntary screening service, are currently being presented at the British Cardiovascular Society’s annual conference in Manchester.
