Chronic coronary syndrome (CCS) is a heterogeneous group of diseases encompassing obstructive and non-obstructive coronary atherosclerotic disease with or without previous myocardial infarction (MI) or coronary revascularization, in addition to the disease diagnosed only by non-invasive tests. According to data from the Global Burden of Disease (GBD) Study, the total number of people living with ischemic heart disease in Brazil, whether symptomatic or not, increased from 1.48 million to more than 4 million between 1990 and 2019. Population growth, aging, and the increase in diagnosis are the main justifications for this phenomenon.,
Although remaining the main cause of death, mortality from ischemic heart disease has decreased over the last three decades in practically all of Brazil, although some regional variations have been described.– Men are more affected than women, and an inverse relationship is described between the mortality rate from ischemic heart disease and the educational or economic level of the regions., Despite the growing existence of national data on ischemic heart disease, regional or local cohorts to assess its long-term prognosis are scarce, even more so if we consider the need for frequent updates regarding emerging treatment strategies.
