Perimenopause: A Critical Window for Heart Health Intervention

A groundbreaking study published in the Journal of the American Heart Association reveals that perimenopausal women are twice as likely to have low cardiovascular health scores compared to those with regular menstrual cycles. The research, based on data from the National Health and Nutrition Examination Survey (2007-2020) involving 9,248 women, used the American Heart Association's Life's Essential 8™ (LE8) metrics to assess heart health. The findings show that median LE8 scores declined from 73.3 in premenopausal women to 69.1 in perimenopausal women and 63.9 in postmenopausal women. The decline was largely driven by significantly higher cholesterol and blood sugar levels, with perimenopausal women 76% more likely to have low cholesterol scores and 83% more likely to have low blood sugar scores. The study highlights perimenopause as a critical 'window of opportunity' for early intervention, as hormonal fluctuations during this transition can negatively impact cardiovascular risk factors.

Lead author Dr. Amrita Nayak emphasized that the perimenopausal period shows the first significant jump in low heart health odds compared to premenopausal baselines. Senior author Dr. Garima Arora urged women to be proactive during perimenopause, checking blood pressure, cholesterol, and blood sugar levels, and adopting heart-healthy habits like the DASH diet and regular exercise. The study also noted that diet scores were consistently low across all reproductive stages, suggesting nutrition is a key area for intervention. Sleep duration scores remained high despite reported sleep difficulties, indicating quality may be more affected than quantity.

Dr. Stacey E. Rosen, volunteer president of the American Heart Association, underscored the importance of recognizing female-specific risk factors during pregnancy, perimenopause, and menopause. The study's next steps involve tracking hormone levels and heart health over several years to clarify long-term impacts. This research reinforces the need for clinicians to begin screening for hypertension, hyperlipidemia, and diabetes earlier in the perimenopausal transition, potentially preventing cardiovascular disease later in life. The findings are particularly timely given projections that 6 in 10 U.S. women will have at least one type of cardiovascular disease by 2050, as noted in a related American Heart Association news release.
