According to statistics, several patients from the group of patients with disease “2”, having the same focus, have two different deficiencies in their anamnesis, which increases the risk of the following pathologies in the future. Among the few studies found, in 30% of patients the phenomenon is found in combination with cancer and cardiovascular disease, including myocardial infarction, stenting or coronary angioplasty.
Despite the complexity of disease “2” and its slow development, doctors are trying
