In many industrialized countries, the decline in cardiovascular mortality over the past 30 years is largely attributable to early detection, drug treatment, and control of hypertension. However, the decline in cardiorespiratory mortality in the United States has not been evenly distributed across racial groups, and hypertension directly accounts for half of the mortality gap between black and white Americans (Pan et al., 2020). Blood pressure (BP) is influenced by various social, cultural and environmental factors, including health behaviours, access to medical care and environmental exposures (Kramer et al., 2017). Education, money, and financial stress are all factors that affect blood pressure, as demonstrated by examining factors associated with differences in blood pressure between races. However, most of these studies focused on differences between African-Americans and whites, did not include Asian or Hispanic groups, and they did not capture the changing demographics of the United States (Pan et al., 2020 year). Few studies have also examined how the use of certain antihypertensive medications varies by race/ethnicity. Whereas the Joint Central Committee on the Detection, Evaluation, and Drug Treatment of Hypertension recommends diuretics as first-line treatment for most hypertensive patients. continue…
