Key result
Heart rate variability parameters were uniformly reduced in type 2 diabetics and did not differ significantly based on the degree of glycemic control, blood pressure control, or the presence of individual cardiovascular risk factors other than resting heart rate.
Why the study?
Does good glycemic and blood pressure control improve heart rate variability in type 2 diabetics?
Population
138 under-treatment Gujarati type 2 diabetics, mean age 56 years, mean diabetes duration 6 years.
Comparison
Good glycemic control and optimum blood pressure… vs Poor glycemic control and non-optimum blood…

HRV reduction in T2DM appears independent of glycemic or BP control; leaves open whether tighter targets mitigate dysautonomia.

p-value: p=>0.05
Heart rate variability is reduced in type 2 diabetics and does not significantly differ based on the degree of glycemic or blood pressure control, suggesting diabetes itself is the primary driver of cardiac dysautonomia.
Solanki et al. (2016) conducted an observational in Type 2 diabetes mellitus (n=138). Poor glycemic and blood pressure control vs. Good glycemic and blood pressure control was evaluated on Heart rate variability (HRV) parameters (time domain, frequency domain, and Poincare plot) (p=>0.05). Heart rate variability parameters were uniformly reduced in type 2 diabetics and did not differ significantly based on the degree of glycemic control, blood pressure control, or the presence of individual cardiovascular risk factors other than resting heart rate.
