Trigger finger is associated with risk of incident cardiovascular disease in individuals with type 2 diabetes: a retrospective cohort study

Introduction Trigger finger is one of the complications affecting the upper extremity in patients with diabetes. Diabetes is also a well-known risk factor that predisposes individuals to cardiovascular diseases (CVDs). This retrospective cohort study aimed to establish the association between trigger finger and the patients with incident CVD with type 2 diabetes. Materials and methods Trigger finger was diagnosed by palpating a thickened tendon during flexion or on the manifestation of a locking phenomenon during extension or flexion of either ?nger. The relationship between trigger finger and other clinical parameters or complications of diabetes was examined by a comparative analysis. Cox regression analysis was used to evaluate the association between trigger finger and incidence of CVD. We calculated the propensity scores using sex, body mass index, age, smoking status, duration of diabetes, estimated glomerular filtration rate, hypertension, dyslipidemia, and hemoglobin A1c as the number of patients with incident CVD during the follow-up period was low. Results Among the 399 patients with type 2 diabetes, 54 patients had trigger finger. Patients with trigger finger were significantly older in age and had been suffering from diabetes for a longer duration. They also displayed worse renal function and glycemic control, along with a higher incidence of hypertension, neuropathy and nephropathy. During the average 5.66 +/- 1.12 years of follow-up, a total of 18 incidents occurred. According to the Cox regression analysis, trigger finger was shown to be associated with enhanced risk of the incidence of CVD after adjustment for the covariates (adjusted HR=3.33 (95% CI 1.25 to 8.66), p=0.017). Conclusions Trigger finger is associated with the risk of incident CVD in patients with type 2 diabetes. Thus, clinicians must consider these factors at the time of diagnosis of such patients.
