QUIET WARRIOR – Rationale and design: An ancillary study to the Women's IschemiA TRial to Reduce Events in Nonobstructive CAD (WARRIOR)
Background: Cardiovascular disease is the leading cause of death among women in the US, predominantly due to ischemic heart disease (IHD). There is a notable deficiency in therapies tailored for IHD in women, who often present with variable symptoms that delay diagnosis and treatment. In many cases,...

| Summary: | Background: Cardiovascular disease is the leading cause of death among women in the US, predominantly due to ischemic heart disease (IHD). There is a notable deficiency in therapies tailored for IHD in women, who often present with variable symptoms that delay diagnosis and treatment. In many cases, coronary angiography does not reveal obstructive coronary artery disease (CAD) despite increased risk for major adverse cardiac events (MACE) compared with sex and age-matched asymptomatic cohorts. Objectives: The Women's IschemiA TRial to Reduce Events in Nonobstructive CAD (WARRIOR) evaluates intensive medical treatment for women with Ischemia with No Obstructive Coronary Arteries (INOCA). The QUIET WARRIOR sub-study aims to improve predictive tools for adverse outcomes by detailed analysis of Coronary Computed Tomography Angiography (CCTA) data and biorepository samples. These data will also uncover pathophysiological mechanisms associated with angina and MACE, improving predictive tools for symptomatic women with INOCA. Methods: This ancillary study will analyze CCTA images from 600 WARRIOR subjects. It will assess clinical, social, and coronary artery variables, including plaque characteristics and markers of inflammation. Advanced imaging techniques and machine-learning models will be employed to quantify plaque features and predict clinical outcomes. Expected results: The study aims to elucidate associations between CCTA-derived plaque characteristics, ischemic symptoms, and MACE. Anticipated findings include correlations of specific plaque attributes with angina severity and novel insights into inflammatory markers. Socioeconomic variables will also be examined for their impact on cardiovascular risk. Conclusion: The QUIET WARRIOR sub-study will advance the understanding of INOCA in women, integrating clinical, imaging, and socioeconomic data to enhance risk prediction and guide personalized therapeutic strategies. This research will address critical gaps in managing nonobstructive CAD, promoting more equitable cardiovascular care. |
