Heart disease is one of the leading causes of death around the world, and many people require surgery to treat severe cases.

One common procedure is coronary artery bypass grafting, often called heart bypass surgery. This operation helps improve blood flow to the heart by creating a new path around blocked arteries. It can be life-saving, especially for people with advanced heart disease.

Although this surgery is widely used and has improved over the years, new research shows that not all patients receive the same level of care. A recent study from Michigan Medicine has found that older women are more likely than men to be treated at hospitals with lower quality, and this may lead to worse outcomes.

The study was published in the journal JAMA Network Open. Researchers looked at nearly 450,000 Medicare patients aged 65 and older who had heart bypass surgery between late 2015 and early 2020. By analyzing such a large group, the team was able to identify patterns in where patients received care and how they fared after surgery.

The findings revealed a clear difference between men and women. Women were about 26 percent more likely than men to have their surgery at hospitals considered low quality. These hospitals were defined as those with higher death rates within 30 days after surgery.

This difference in hospital quality had a real impact on survival. At lower-quality hospitals, about 7 percent of women died within 30 days after surgery, compared to nearly 5 percent of men. When comparing high-quality and low-quality hospitals, the gap in death rates between men and women became even larger.

The researchers also found that women often arrived at the hospital in worse condition. Many had unplanned hospital admissions before surgery, which means they may not have had enough time for careful planning and preparation. In addition, women tended to have more existing health problems, which can make surgery more risky.

Another important factor is that women are often referred for surgery later than men. Previous research has shown that women with heart disease may not be diagnosed or treated as early as men. This delay can allow the disease to become more severe, increasing the risks during surgery.

Hospital experience also plays a role. Hospitals that perform more heart bypass surgeries each year usually have better results. These high-volume centers often have more specialized teams and better systems in place to care for complex patients. However, women in this study were less likely to be treated at these higher-quality centers.

Dr. Catherine M. Wagner, the lead author of the study, explained that both hospital quality and patient condition contribute to the differences in outcomes. She emphasized the need to improve care at lower-quality hospitals and ensure that women are referred to better-performing centers.

Another researcher, Dr. Andrew Ibrahim, noted that increasing gender diversity in heart surgery teams could also help. Having more women involved in cardiothoracic surgery may improve understanding and care for female patients.

These findings are part of a larger concern about women’s heart health. A national study published in 2023 showed that death rates for women undergoing heart bypass surgery have increased over the past decade. Experts have called this a warning sign that more attention is needed.

In response, there have been efforts to improve women’s health research and care. In 2023, the United States government launched a major initiative focused on women’s health, along with significant funding to support new research and better treatment approaches.

Despite progress in many areas, this study shows that important gaps still exist. Women continue to face higher risks, not only because of biological differences but also because of where and how they receive care.

The researchers believe that improving hospital quality and ensuring fair access to high-quality care could make a big difference. By addressing these issues, it may be possible to reduce death rates and provide better outcomes for all patients.

This study highlights the importance of equal access to high-quality healthcare. It also reminds us that improving outcomes is not only about medical advances but also about ensuring that every patient receives the best possible care.
