Hemodynamics in Labile Hypertension
نویسندگان
چکیده
a high cardiac output and a lower than normal total peripheral resistance. It was our feeling, based on this original work, that this pattern might be an early phase or a benign type of essential hypertension. This is a report of the first follow-up study done on a group of such labile hypertensive patients in whom the hemodynamics and clinical status have been studied over a period of 50 months to determine which one of the two possibilities mentioned might be true.

The hemodynamic response to mental stress (mental arithmetic) was studied in adolscents with varying risk factors for essential hypertension (EH), One group (genetic) consisted of normotensive well adolescents who had at least one parentnt with EH. Another group (labile) consisted of adolescents with labile hypertension each of whom also had at least one pare with EH. The control population con...

متن کاملGeneral anesthesia with remifentanil for cesarean section in a parturient with severe mitral and tricuspid regurgitation
Valvular heart lesions have deleterious effects on hemodynamics in parturients during pregnancy. Cesarean section with an opioid-based general anesthesia is used to alleviate the adverse effects. We described a case of a 28-year-old primigravida at 37 weeks’ gestation with a diagnosis of severe mitral regurgitation, tricuspid regurgitation, and pulmonary hypertension in active labor. Cesarean s...
متن کاملHemodynamic Responses to Graded Treadmill Exercise in Young Untreated Labile Hypertensive Patients By ARTHUR
Twenty labile hypertensive patients and their age-matched controls were studied at rest and during five levels of treadmill exercise. Intra-arterial blood pressure, cardiac output, and various aspects of the pressure pulse wave were analyzed under these conditions. Exercise provoked diastolic hypertension in 30% of the patient group. Mean group pressure responses demonstrated an almost constant...
متن کاملHemodynamics of the Master Two-step Test in Hypertension and Healed Myocardial Infarction.
ALTHOUGH the two-step exercise test of Master1 has been used extensively to produce electrocardiographic changes of acute coronary artery insufficiency, results of directly measured hemodynamic changes during the recovery period have not been reported. Indirectly measured hemodynamic changes following this two-step test have been reported infrequently since the tables of standardized stress wer...
