To the Editor,

We thank all of the authors for their valuable comments, and we were delighted to see your interest to our study (1), entitled “Association of P-wave dispersion and left ventricular diastolic dysfunction in non-dipper and dipper hypertensive patients,” published in the April issue of The Anatolian Journal of Cardiology 2014; 14: 251-5.

You are right about the mentioned parameters, such as e’, a’, and E/e’; this may be a deficiency of our study. Nevertheless, we will take your advice into consideration for future research.

Deficient of normal fall of blood pressure at night is associated with increased risk of cardiovascular disease (2). Reverse-dipper or riser patients generate a small portion of hypertensive patients (3). Although this group is at risk for stroke (commonly intracranial hemorrhage), especially in elderly patients (4). However, despite the evidences, reverse-dipping is not mentioned in the valid guide- lines currently (5). The small number of patients was another deficiency in our study to obtain wide-angle data. Consequently, we did not examine and create a reverse-dipper group. Studies involving more patients with longer follow-ups may contribute valuable parts of further guidelines.
