HRT Tablet Study Raises Concerns Over Heart Disease and Clots
A new study published in the BMJ has reignited the debate over the cardiovascular risks associated with hormone replacement therapy (HRT) in menopausal women, focusing notably on the usage of HRT tablets. As concerns regarding heart disease and blood clots mount, an array of experts weigh in on the research’s implications and the validity of its findings.
Study Overview
The publication, titled Contemporary menopausal hormone therapy and risk of cardiovascular disease: Swedish nationwide register-based emulated target trial by Therese Johansson et al., was released on November 27, 2024. The investigation highlights the association between various forms of HRT and their potential impact on heart health, specifically noting increased risks of heart disease and venous thromboembolism (VTE). However, several experts question the robustness and relevance of the findings.
Expert Opinions
Dr. Paula Briggs, a Consultant in Sexual and Reproductive Health at Liverpool Women’s NHS Foundation Trust and Immediate Past Chair of the British Menopause Society, has raised critical points regarding the study’s methodology. “Observational studies are inherently flawed due to difficulties in confirming patient compliance and accurately recording outcomes. This study does not provide new data that should change clinical practices in the UK,” she states.
Briggs emphasizes that while age naturally increases the risk of cardiovascular events in women, the precise dangers posed by HRT tablets remain unclear due to insufficient demographic information in the study. "Transdermal estrogen, in particular, minimizes the risk of VTE," she notes.
Confounding Factors and Limitations
Another significant critique comes from Dr. Stephen Burgess of the MRC Biostatistics Unit at the University of Cambridge. He clarifies that the study’s approach of making observational comparisons instead of conducting randomized trials introduces potential biases. “While the analysis has its advantages, it is not free from the influence of confounding factors such as BMI, which have not been thoroughly accounted for,” he explains.
Rachel Richardson, Methods Support Unit Lead at Cochrane, provides further context, acknowledging that the data utilized came from the Swedish national patient register. This database only captures women diagnosed within hospital settings, potentially excluding those diagnosed in primary care. “The authors didn’t account for critical variables, and with more than 900,000 women in the study, findings risk being misleading due to the rare outcomes they aimed to identify,” Richardson cautions.
Risk vs. Benefits of HRT
While the latest findings confirm previously established associations between oral HRT and increased risks of clotting diseases—including heart attacks and strokes—these insights should not cause alarm without a thorough discussion of the risks versus benefits with healthcare professionals. “Patients should carefully weigh the pros and cons of using HRT, engaging in meaningful discussions with their doctors,” Dr. Burgess advises.
The Path Ahead
The consensus among the experts suggests that rather than altering clinical practices, the study reinforces the need for rigorous patient assessments. Women with a low baseline risk of cardiovascular disease or VTE should have clear communication about the increased risks when considering oral HRT.
As the discourse continues, the medical community urges women to consult their healthcare providers to make informed decisions that cater to their individual health needs and risks.
