Many chronic non-communicable diseases have been extensively studied today, among which cardiovascular diseases stand out, since they are accompanied by high rates of hospital admissions, physical disabilities and even deaths. This group of diseases includes hypertension, atherosclerosis, heart failure, acute myocardial infarction and peripheral vascular disease, which includes strokes and aneurysms. Although research is being carried out to reduce their incidence, morbidity and mortality, and although there are now modern diagnostic techniques and treatments for them, they still represent a major challenge for public health worldwide. For this reason, we believe that assessing the population's level of knowledge on this subject is important in order to preventively minimize its serious consequences. In addition, we believe that it is also the role of universities to make a scientific and extensionist contribution so that educational actions and effective, low-cost interventions can be developed, favoring the preventive nature of this and many other diseases.
