Covid-19 disease emerged in December 2019 in Wuhan City, Hubei Province, China. It is caused by the new coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the seventh coronavirus identified to date, which is different from other coronaviruses that cause pneumonia and common cold.Due to the greater and faster transmissibility, a pandemic was declared by the World Health Organization on 11 March 2020. Since then, several studies worldwide have been conducted and published with the aim of determining the […]

It is a current research method to evaluate the outcome of diseases over decades, mainly in most prevalent diseases such as myocardial infarction, a public health issue with a significant toll in morbidity and mortality of the population. In addition to evolving over time, local conditions may also contribute to differences in outcome, mainly in countries with continental dimensions as Brazil is, as well as with large populations (206.081.432 habitants in 2016; 210.147.125 habitants in 2019). Other epidemiologic variables, such […]

Ischemic heart disease (IHD) is the leading cause of mortality in the world, being responsible for more than 9 million deaths in 2016. The trend profile of IHD mortality rates varied according to the economic level of countries. Developed nations have experienced a dramatic reduction in IHD mortality rates in recent years, perhaps attributed to a greater focus on primary prevention and better diagnosis and treatment. However, in the so-called developing countries, the reduction was not so accentuated, representing a […]

Heart failure (HF) with reduced ejection fraction (HFrEF) has increased significantly in the last three decades and is associated with high morbidity and mortality. In patients with HF, exercise intolerance suggested by dyspnea or fatigue during exertion is the hallmark of the disease. Additionally, health-related quality of life is known to be markedly reduced in HFrEF patients. The severity of this exercise limitation and low quality of life has been shown to correlate to worse prognosis. For this functional and […]

Cardiovascular diseases (CVD) are currently the leading cause of death in Brazil and in the world, with 80% of the cases occurring in low- and middle-income countries. It impacts these countries economies negatively, with reductions in the Gross Domestic Product (GDP), and increases in the burden on already precarious health care systems. The risk factors associated with CVD are largely preventable, and raising awareness and increasing access to primary health care for prevention are key factors for reducing events. The […]

Cardiovascular diseases (CVD) are the leading cause of mortality and morbidity worldwide. Because several CVD have sequelae that significantly impact the life of affected individuals, knowing the importance of those diseases, as well as their associated factors, is essential to develop preventive measures to reduce that impact.– The study published in this issue of the Arquivos Brasileiros de Cardiologia conducts an epidemiological assessment of CVD in Portuguese-speaking countries (PSC) from 1996 to 2016, being, in that context, unprecedented and relevant.
