Summary: A new Coronary Risk Score in Women accurately predicts major adverse cardiovascular events, helping to identify high-risk women and improve resource allocation for early intervention, according to a study published in Radiology: Cardiothoracic Imaging.

Key Takeaways

  1. Women are often overlooked in cardiovascular studies, making the development of a tailored risk stratification model, such as the Coronary Risk Score in Women (CORSWO), crucial for addressing gender-specific differences in the clinical presentation of coronary disease.
  2. The CORSWO model, which incorporates clinical, exercise, and imaging-based variables, accurately predicts major adverse cardiovascular events, particularly in high and very high-risk women, outperforming other existing risk models.
  3. By categorizing women into four risk levels, the CORSWO allows physicians to prioritize treatments and allocate resources more effectively, aiding early intervention to prevent serious outcomes like heart attacks and sudden cardiac death.

A new risk score accurately predicts and categorizes the risk of major adverse cardiovascular events, such as heart attack, in women. The findings were published in Radiology: Cardiothoracic Imaging, a journal of the Radiological Society of North America (RSNA).

Gender Gap in Cardiovascular Research

According to the Centers for Disease Control and Prevention, heart disease is the leading cause of death in U.S. women. The same can be says for women in Latin America, Europe, Asia, and Pacific countries. However, since men are more likely to suffer from heart conditions such as coronary artery disease, women tend to be overlooked in cardiovascular studies.

“Women are often underrepresented in research studies, and in some settings may be excluded,” says study lead author Guillermo Romero-Farina, MD, PhD, cardiologist and senior researcher at the Vall d’Hebron University Hospital, Vall d’Hebron Research Institute and CIBERCV in Barcelona. “Risk stratification in women is particularly important because the clinical presentation of coronary disease in women may differ from that in men and is often atypical.”

Coronary risk stratification models are an important tool physicians use to identify which patients are most likely to experience major adverse cardiovascular events, such as heart attack, stroke or even death. Establishing a Coronary Risk Score in Women (CORSWO) may aid in the prediction of major cardiovascular events.

Imaging Model Enhances Heart Risk Predictions

In this retrospective study, Romero-Farina and colleagues analyzed the data of 2,226 women aged 40 to 93 years who were referred to the Nuclear Cardiology Unit at Vall d’Hebron University Hospital for risk assessment and evaluation.

All patients underwent gated SPECT myocardial perfusion imaging, which is an imaging procedure that measures left ventricular function and myocardial perfusion at the same time. The average follow-up time occurred around was approximately four years. The maximum follow-up time was 10 years, and all follow-ups occurred in the hospital because of a major adverse cardiovascular event.

Using eight variables, the CORSWO calculated the risk of a cardiac event in patients and categorized them into four risk levels: low, moderate, high, and very high.

“By grouping patients into different risk levels—ranging from low to very high risk—doctors can better focus resources and treatments on those who need them the most,” Romero-Farina says.

The model accurately predicted major adverse cardiovascular events in women who were categorized as high and very high risk and performed better than other risk models. The researchers note that this novel approach of incorporating clinical, exercise and imaging-based variables is important in accurately calculating the risk of cardiac events in women.

“The study provides additional insights into identifying high risk or very high-risk women,” Romero-Farina says. “This approach helps us catch potential heart issues earlier, especially serious events like heart attacks and sudden cardiac death, which are the outcomes cardiologists are most concerned about preventing.”
