Shocking Link Between Hypertensive Disorders of Pregnancy and Early Heart Disease Risks!

Recent research has unveiled a startling connection between hypertensive disorders of pregnancy (HDP) and the accelerated onset of coronary artery disease (CAD) in women. Findings from an observational analysis reveal that women who experience conditions such as preeclampsia, gestational hypertension, or chronic hypertension during pregnancy are at a far greater risk of developing CAD compared to their normotensive counterparts.

The study, conducted by experts at the Mayo Clinic, highlights that women with a history of HDP face significantly increased odds of experiencing myocardial infarction, regardless of whether it involves obstructive or non-obstructive coronary arteries, also known as MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries). Alarmingly, nearly one in five women diagnosed with acute coronary syndrome after HDP was found to have MINOCA.

Vesna D. Garovic, MD, PhD, and senior author of the study, emphasized the importance of early detection and treatment. “This study underscores the need for timely detection and treatment of nonobstructive disease, in addition to traditional risk factors,” she stated.

Previous imaging studies had already established a link between preeclampsia and an increased atherosclerotic burden. However, this recent research takes it a step further by connecting these vascular changes to real cardiovascular events. It turns out that women who had preeclampsia manifest more atherosclerosis in their coronary arteries than those who did not have the condition during pregnancy.

The study highlights the crucial follow-up care necessary for women who have experienced hypertension during pregnancy. “When women later in life report that they had previously experienced preeclampsia or early delivery due to complications, it underscores the urgency to monitor and manage risk factors diligently,” added Dr. Garovic.

Notably, not all women with a history of HDP develop coronary artery disease, suggesting that factors influencing long-term outcomes are complex. Even within cases of preeclampsia—which typically presents with hypertension, proteinuria, and broader systemic issues—different underlying mechanisms may lead to varying outcomes. Research indicates that impaired immunomodulation and oxidative stress could be contributing factors, each with distinct implications for women's health.

The study analyzed incidents of CAD over a 14-year period, examining 506 female residents of Olmsted County, MN, who had delivered at least one live baby. Among these women, a significant percentage displayed a history of HDP and were generally younger when encountering CAD compared to their normotensive peers. Additionally, they exhibited a higher body mass index (BMI) and prevalence of diabetes and hypertension, all of which amplify cardiovascular risk.

Strikingly, transitioning into the specifics, women with a history of HDP were found to be nearly twice as likely to receive a MINOCA diagnosis compared to those without a history of HDP. Furthermore, the findings indicated a remarkable prevalence of MINOCA among women impacted by HDP, raising urgent questions about sex and reproductive-related cardiovascular risk factors.

Moving forward, Dr. Garovic urges that future research combine preclinical and human studies to better understand the specific mechanisms driving the different types of MINOCA in women after experiencing HDP.

Michael C. Honigberg, MD, from Massachusetts General Hospital, expressed in an editorial that current knowledge about the clinical outcomes of CAD in women with HDP is still lacking granularity. He asserts that while the connection between atherosclerosis and HDP is increasingly clear, effective approaches to prevent long-term cardiovascular disease in this demographic remain insufficiently defined.

The revelation from this study serves as a crucial wake-up call for women who have experienced HDP and healthcare providers to remain vigilant in monitoring cardiovascular health, emphasizing the need for proactive strategies to safeguard their heart health in the years following pregnancy.
