Objective: Resistant hypertension (RH) is associated with an increased risk of cardiovascular events.Mean platelet volume (MPV) has been shown to indicate platelet activation and is associated with increased cardiovascular disease risk. In our study, we aimed to evaluate the relationship between mean platelet volume and resistant hypertension.
Method: A total of 279 patientswere included in our study and divided into three groups (GroupI: seventy-eight patients with resistant hypertension, group II: seventy-nine patients with controlled hypertension and group III: one-hundred-five patients without hypertension). Routine laboratory tests and ambulatory blood pressure measurement (ABPM) were followed up in all patients.
Results: Of the patients in the study, 25% were female while 75% were male, and the mean age was 56.5 ± 11.8 years. The mean MPV values were found to be 9.34 ± 1.49 fL in the RHT group, 8.82 ± 0.83 fLin the controlled HT group, and 8.5 ± 0.85 fL in the normotensive individuals, and there was a significant correlation between the RHT group and the other groups (RHT versus controlled HT p1 = 0.008, RHT versus normotensive individuals p2 < 0,001). When we compared controlled HT and normotensive individuals, no significant relationship was found between MPV values (p3 = 0,157).
Conclusion: The MPV value was found to be higher in resistant hypertensive patients compared to controlled hypertensive and normotensive patients. MPV values can be used to predict adverse cardiovascular events in RHT patients.
