“…Our study appears as an indicator of the modifiable structure of HRV with a healthy lifestyle in diabetic patients. Although diabetes mellitus results Adjusted for baseline HbA 1c , 1-year HbA 1c , baseline and 1-year anti-hypertensive and β-blocker Data were presented as mean (standard deviation [SD]) for normally distributed continuous variables Abbreviations: HF, high frequency; HRV, heart rate variability; LF, low frequency; pNN50, percentage of the differences between adjacent normal R-R intervals exceeding 50 milliseconds; RMSSD, square root of the mean squared difference of successive R-R intervals; SDANN index, standard deviation of the mean R-R intervals calculated over a 5-minute period; SDNN, standard deviation of normal to normal R-R intervals; SDNN index, mean of the standard deviation of R-R intervals calculated over a 5-minute period; TP, total power Mobile application systems have been found both beneficial and useful in previous trials regarding heart failure, atrial fibrillation, and primary prevention of cardiovascular diseases [12,14,15]. Moreover, these systems have presented trustworthy positive results in the self-management of diabetes mellitus [16].…”
