Abstract:
Patients with non-dipper hypertension are known to carry a high risk of cardiovascular complications. In this study, we hypothesized that non-dippers may be associated with platelet dysfunction and it can be determined by mean platelet volume (MPV). A total of 216 outpatients treated with antihypertensive drugs for at least 6 months were enrolled. Dipper and non-dipper patterns were detected and clinical, laboratory and ambulatory blood pressure recording data were matched between non-dipping and dipping groups. MPV was significantly higher in patients in non-dipping than dipping groups (p<0.001). In correlation analyses, MPV was negatively correlated with the rate of systolic and diastolic fall at night (p<0.001, r=-0.46) and (p<0.001, r=-0.43), respectively. Also MPV was correlated with nocturnal pulse pressure (p=0.001, r=0.22). Other variables were similar between non-dipping and dipping groups. The present study showed that MPV is higher in non-dipping than dipping hypertensive patients. Platelet activation or dysfunction probably is an alternative mechanism for increasing cardiovascular events in non-dippers.

Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...

Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
