Final answer:
An example of health care disparity is the different levels of treatment provided to insured versus uninsured cardiac patients, which is indicative of broader systemic health care inequalities affecting various demographics, primarily based on socioeconomic and racial factors.
Step-by-step explanation:
An example of health care disparity is when a physician treats cardiac patients with insurance more aggressively than uninsured patients. This reflects unequal treatment based on patients' insurance status and can lead to differences in health outcomes. Health care disparities often occur due to factors such as socioeconomic status, race, ethnicity, and various social determinants. For instance, African Americans have higher rates of chronic diseases and mortality compared to White Americans, influenced by factors like medical mistrust, systemic inequalities in economics, housing, and health care systems, as well as lower representation in medical research.
