Abstract

to estimate the prevalence and factors associated with angina pectoris in the Brazilian adult population and per federated units. Cross-sectional descriptive study that analyzed data from the National Survey of Health 2019 and assessed the prevalence of angina in the Brazilian population. Angina was defined as chest pain or discomfort when climbing hills or stairs, or when walking fast on flat terrain (angina I) or when walking at normal speed on flat terrain (angina II). Prevalence, crude and adjusted prevalence ratios were calculated, with a 95% confidence interval, according to sociodemographic characteristics (sex, age group, self-reported race/skin color and region of residence) and federative units. The prevalence of mild angina (grade I) was 8.1% and of moderate/severe angina (grade II) was 4.5%, being both more prevalent in women (9.8 and 5.5%, respectively). The prevalence increased progressively with age and was inversely proportional to years of formal study. Grade I angina was higher in individuals self-reportedly black and residents of Sergipe (10,4%). Angina II was more prevalent in people self-reportedly brown and living in Amazonas (6.3%). Angina affects more than 10% of the Brazilian population aged 18 years old and more, with higher prevalence in states in the North and Northeast. This is a problem that affects the most vulnerable populations unequally, which places coronary heart disease as a public health problem and points to the need to think about public policies aimed at these strata of the population.

Highlights

The World Health Organization (WHO) estimates that, in 2016, cardiovascular diseases (CVD) were responsible for 17.9 million deaths worldwide, representing 31% of all global deaths
Associated with age and gender, the characterization of angina helps to predict the probability of coronary ischemic disease, in some cases it may result from conditions other than coronary artery disease (CAD), such as anemia, hyperthyroidism, respiratory diseases and valvular diseases[4]
The prevalence was higher among residents of the rural region (9.8%, 95% confidence intervals (95%CI) 9.1-10.5; adjusted Prevalence ratios (PR) 1.06, 95%CI 1.04-1.08) compared to those living in the urban area (7.8%, 95%CI 7.5-8.2) (Table 1)

Summary

Introduction

The World Health Organization (WHO) estimates that, in 2016, cardiovascular diseases (CVD) were responsible for 17.9 million deaths worldwide, representing 31% of all global deaths. From the Latin Angina Pectoris (AP), is a common symptom of coronary artery disease (CAD) that impacts an individual’s quality of life[3]. It typically expresses as a chest discomfort usually triggered by physical activity or emotional stress, which gets better after rest or use of nitroglycerin and is mostly caused by myocardial hypoxia resulting from obstructive or non-obstructive CAD4. Associated with age and gender, the characterization of angina helps to predict the probability of coronary ischemic disease, in some cases it may result from conditions other than CAD, such as anemia, hyperthyroidism, respiratory diseases and valvular diseases[4]
