This article highlights the significance of health equity and the role of community-engaged research in addressing stroke disparities, including concepts around health equity as the fair and just opportunity for everyone to attain their highest level of health and well-being. Social determinants impact stroke incidence, prevalence, morbidity, and mortality, which emphasizes the importance of intersectionality and social risk-informed care. A comprehensive roadmap for achieving health equity in stroke through the integration of community-engaged research is presented, including the necessity of community involvement in all aspects of research. Community is defined beyond geographic boundaries, highlighting the importance of shared identities and values. The process of developing targeted goals with communities toward social justice reform is reviewed, including an evolved community engagement framework, emphasizing the need for training to inform about issues and collaborative leadership models. Several stroke disparities intervention studies are highlighted, demonstrating the successful incorporation of community engagement into intervention design and intervention platforms. For enhanced engagement, the use of community health workers and better integration of community health worker models are essential. There may be a critical need for community engagement to optimize inclusion in clinical trials. Finally, acknowledging the complexities of research around decreasing stroke disparities in prevention, treatment, and recovery, this article delves into a framework for understanding the mechanisms by which interventions affect inequities and the need for multifaceted solutions with the community as a partner.

The progressive transformation of hypoperfused viable tissue, the ischemic penumbra, into infarction is a mechanism shared by patients with ischemic stroke if timely reperfusion is not achieved.

The estimated average IGR in patients with acute large vessel occlusion stroke is 5.4 mL/h although there is wide variability based on ischemic stroke subtype, occlusion location, presence of collaterals, and patient baseline status.

The IGR defines a spectrum of clinical stroke phenotypes, often dichotomized into fast and slow progressors. An IGR ≥10 mL/h and the perfusion metric hypoperfusion intensity ratio ≥0.5 are commonly used definitions of fast progressors.

Abnormalities of menstruation, the shedding of the uterine lining at the beginning of each menstrual cycle, may offer clues about stroke risk in young and midlife women. Endometrial and structural uterine abnormalities are associated with anemia and may be associated with hypercoagulability, possibly increasing stroke risk. Patient factors that influence both menstruation and stroke risk include coagulopathies, polycystic ovarian syndrome, endometriosis, migraine, and other systemic disorders, in addition to menopause. Environmental and iatrogenic factors that influence both menstruation and stroke risk include hormonal contraceptives, nicotine, xenoestrogens, phytoestrogens, oophorectomy, and hysterectomy. Importantly, secondary stroke prevention can affect menstruation.
