Enhanced external counterpulsation (EECP) improves biomarkers of glycemic control in patients with non-insulin-dependent type II diabetes mellitus for up to 3 months following treatment.

AIMS: The purpose of the present study was to evaluate the potential clinical benefits of EECP on glycemic parameters [fasting plasma glucose (FPG), postprandial glucose (PPG120), glycosylated hemoglobin (HbA1c)] in patients with a clinical diagnosis of type II diabetes mellitus (T2DM).

METHODS: Thirty subjects (60.7 ± 1.9 years) with T2DM were randomly assigned (2:1 ratio) to receive either 35 1-h sessions of EECP (n = 20) or time-matched control of standard care (n = 10). FPG, PPG120, and HbA1c were evaluated before and at 48 h, 2 weeks, 3 and 6 months following EECP treatment or time-matched control.

RESULTS: EECP significantly decreased FPG (-14.6 and -12.0 %), PPG120 (-14.6 and -13.5 %), and HbA1c (-11.5 and -19.6 %) 48 h following EECP and 2 weeks following EECP, respectively. HbA1c remained significantly reduced at 3 months following EECP (-14.3 %). The homeostasis model assessment of insulin resistance (-31.1 %) and whole-body composite insulin sensitivity index (+54.2 %) were significantly improved 48 h following EECP. Nitrite/nitrate (NO x ) was significantly increased 48 h following EECP (+48.4 %) and 2 weeks (+51.9 %) following EECP treatment.

CONCLUSIONS: Our findings provide novel evidence that EECP improves glycemic control in patients with T2DM that persist for up to 3 months following treatment.
