Chewing of Qat leaves which contain amphetamine alkaloids is a traditional drug practice in the horn of Africa. Cathine and cathinone are responsible for the desired psychogenic (suppression of hunger, mind stimulation, euphoria) and sympathicomimetic effects. In this study, we monitored seven volunteers during a traditional qat ritual. An increase in systolic and diastolic pressure was observed in three patients including one presenting predisposing chronic arterial hypertension. Peak pressure was observed approximately seven hours after beginning the ritual. The three patients presenting pressure changes were not significantly different from the four unaffected patients with regard to age or duration of qat use. These findings suggest that qat use by untreated hypertensive patients who react strongly to vasoconstrictive effects can lead to hypertension and resulting cardiovascular complications. |
