Objective: To estimate the population prevalence of angina pectoris in the Brazilian adult population according to sociodemographic characteristics and by Federated Units. Methods: Cross-sectional descriptive study that analyzed the data from the National Health Survey (PNS-2019) and assessed angina in the Brazilian population. Angina was defined as chest pain or discomfort when climbing hills or a flight of stairs or when walking fast on plane (angina I) or when walking at normal speed on plane (angina II). Prevalence, crude, and adjusted prevalence ratio were calculated, with a 95% confidence interval (95% CI), according to sociodemographic characteristics (gender, age group, self-reported race/skin color and region of residence) and federative units. Results: The prevalence of mild angina (grade I) was 8.1% and of moderate / severe angina (grade II) was 4.5%, both more prevalent in women (9.8% and 5.5%, respectively). The prevalence increased progressively with age and were inverse to the years of formal study. Grade I angina was higher in individuals of self-reported black race/skin color and residents of Sergipe (10,4%). Angina II was more prevalent in people of self-reported brown race/skin color and in Amazonas (6.3%). Conclusion: Angina affects more than 10% of the Brazilian population over 18 years old, with higher prevalence in states in the North and Northeast. It is a problem that affects the most vulnerable populations unequally, revealing the importance of coronary heart disease as a public health problem and the need to think about Public Policies aimed at these strata of the population.
