Prediabetes and Cardiac Autonomic Neuropathy
Prediabetes is a
                    condition where an individual has abnormally high
                    blood glucose, while not high enough to be diagnosed
                    as diabetes. Prediabetes can cause heart and kidney
                    problems. Cardiac autonomic neuropathy (CAN) may be
                    defined as “the
                      impairment of autonomic control of the
                    cardiovascular system.” While the condition is
                    frequently not given much focus, CAN is frequently
                    associated with type 1 and type 2 diabetes. CAN may
                    also be associated with heart problems and
                    mortality. Further, at least one recent study
                    has concluded that CAN is also associated with
                    prediabetes.
                    
                    The investigators involved in the study did a
                    search, electronically, to find individuals, in
                    other studies, with prediabetes, normal glucose and
                    type 2 diabetes. The researchers searched the
                    following databases: Medline, MBASE, Pubmed, Web of
                    science, Scopus and Cochrane. 
                    
                    As a result of the database search, the researchers
                    found 4431 participants who satisfied the analysis’
                    inclusion criteria. The participants included 1730
                    individuals with prediabetes. There were 1999
                    individuals who had normal glucose. And there were
                    702 individuals with type 2 diabetes. And there was
                    a higher than normal number of individuals
                    experiencing CAN.
                    
                    Further, the researcher concluded that “There [was]
                      a higher than expected prevalence of CAN in
                    prediabetes. Early detection of CAN in prediabetes
                    through population screening needs careful
                    consideration in view of the excess morbidity and
                    mortality risk associated with this condition.”
                    
                    The above study underlines the importance of
                    diagnosing prediabetes. And once prediabetes is
                    diagnosed, screening for other known prediabetes
                    comorbidities should then occur -- including
                    screening for CAN. Providers should make it a point
                    to screen for prediabetes. The providers should
                    counsel patients who do have predicates on how to
                    lower the chances of getting type 2 diabetes. The
                    providers should then advise the patients on other
                    prediabetes-associated conditions. This can benefit
                    a patient by potentially improving the patient’s
                    health.
