  • Title: [Incidence of systemic hypertension after orthotopic heart transplantation].
    Author: Jandová R, Fabián J.
    Journal: Cas Lek Cesk; 1990 Jan 05; 129(1):15-9. PubMed ID: 2331711.
    Abstract:
    In a group of 18 patients after orthotopic transplantation of the heart (OTH) operated, 4-56 months previously and treated by combined immunosuppression (Cyclosporin A, corticoids, azathioprine), systemic hypertension was revealed in six and borderline hypertension in three patients. The mechanism of the development of hypertension, after OTH has not been elucidated. As to the circadian rhythm of the blood pressure, as compared with normotensive subjects and patients with essential hypertension, in patients after OTH usually the drop of systemic pressure values does not occur during the night; on the contrary the blood pressure rises during the night. This finding may be due to denervation of the heart after OTH and an abnormal response of baroreceptors to the rise of blood pressure; in this the effect of corticoids may also participate. After a one-year interval the abnormal reaction of the systolic pressure remains preserved, while the 24-hour profile of the diastolic pressure has trend towards normalization.
