In a groundbreaking new study, researchers reveal a significant yet concerning trend: while cardiovascular deaths related to autoimmune diseases have declined over the last decade, women still face a disproportionately high risk compared to their male counterparts.

An extensive analysis of over 127,000 cardiovascular disease-related deaths from 1999 to 2020 showed that although the gap between men and women is narrowing, women remain approximately 50% more likely to die from these complications. For instance, those suffering from rheumatoid arthritis experience CV-related death rates three times higher than men.

A Call for Greater Awareness and Research

Senior researcher Dr. Heba S. Wassif from Cleveland Clinic emphasizes the need for broader research on cardiovascular risks in autoimmune disorders, which affect an estimated 27 million Americans. Despite historical studies highlighting how rheumatoid arthritis patients have different causes of death—like valvular heart disease and pulmonary embolism—further research has been slow to emerge since initial findings were published in the 1950s.

"In recent years, the field of cardio-rheumatology has gained traction, prompting more cardiologists to pay attention to this intersection," said Dr. Wassif. However, the term 'autoimmune disorder' encompasses over 80 distinct diseases, making it challenging to pinpoint specific risks.

Positive Trends Amid Challenges

Good news arises from the findings: the decline in CV-related deaths is likely linked to earlier diagnoses and improvements in biological therapies. Factors like timely treatment of hypertension and high cholesterol levels are also critical.

Multidisciplinary Collaboration is Key

Published in Circulation: Cardiovascular Quality and Outcomes, the study shows that from 1999 to 2020, death rates among women with immune-mediated inflammatory diseases fell from 3.9 to 2.1 per 100,000. Men also saw a decline, although at a slower rate.

This research underscores the crucial need for collaboration among primary care, rheumatology, and cardiology to identify risks early. "Rheumatologists should initiate cardiovascular assessments, ensuring that patients receive comprehensive care and not dismissing symptoms as unrelated to autoimmune diseases," Dr. Wassif cautioned.

Investigating the Gender Gap

While the study does not delve into the reasons for sex disparities in heart health among autoimmune disorder patients, speculations point to factors such as systemic inflammation and hormonal influences. Anomalies like higher rates of arrhythmias and cardiac arrest in women may stem from estrogen's impact on heart rhythms.

In summary, increasing awareness of atypical cardiovascular symptoms in women is imperative. Enhanced early detection, coupled with equitable access to cutting-edge therapies, is critical for improving health outcomes in this vulnerable population. Dr. Wassif emphasizes that understanding and addressing these heightened risks is only the beginning of a larger battle.
