Luteinizing Hormone Pulsatility is Altered in Essential Hypertension

The aim of this investigation was to study the pattern of luteinizing hormone (LH) secretion in men with mild and moderate hypertension. LH pulsatility was evaluated for 8 h in 14 male patients, subdivided into 2 groups: group A, consisting of 8 patients, whose systolic blood pressure ranged between 180 and 160 mm Hg and whose diastolic blood pressure was between 115 and 105 mm Hg; and group B, 6 patients whose systolic blood pressure ranged between 220 and 180 mm Hg and whose diastolic blood pressure was between 104 and 95 mm Hg. Seven healthy males were evaluated as controls (group C). The major changes of LH pulsatility in group A included an increased peak width, increased peak amplitude, and increased peak area. In group B the changes followed the same pattern as in group A, but were more pronounced. The number of LH peaks was reduced, the peak width was increased, and both peak amplitude and peak area were increased as compared to the control group. The pattern of LH pulsatility is altered in essent...
