Abnormal Baroreflex Mechanisms in Congestive Heart Failure
P atients with low output congestive heart failure have less-than-normal slowing of heart rate during pharmacologic increases of arterial pressure, indicating impairment of the arterial baroreceptor-heart rate reflex.1 The mechanism underlying this abnormality is not fully understood and could involve one or more components of the reflex arc, including an afferent limb (generation and transmiss...
متن کاملCONGESTIVE HEART FAILURE IN CHILDREN: A SURVEY OF 114 PATIENTS
During a period of four years between June, IS, 1988 to June, IS, 1992 one hundred and fourteen patients with congestive heart failure (CHF) were admitted to the pediatric department of Taleghani General Hospital. During the above period, 192 patients with heart disease were hospitalized at this department and CHF was the cause of admission in 59.4% of them. Congenital heart disease (CHO) w...
متن کاملMechanisms and management of diuretic resistance in congestive heart failure.
Diuretic drugs are used almost universally in patients with congestive heart failure, most frequently the potent loop diuretics. Despite their unproven effect on survival, their indisputable efficacy in relieving congestive symptoms makes them first line therapy for most patients. In the treatment of more advanced stages of heart failure diuretics may fail to control salt and water retention de...
متن کاملMechanisms of carvedilol action in human congestive heart failure.
The precise mechanism by which beta-adrenoceptor blockers exert their beneficial actions in patients with heart failure remains unclear. Several possibilities have been proposed, including heart rate reduction, beta2-adrenoceptor-mediated modulation of catecholamine release, antagonism of the receptor-mediated toxic actions of norepinephrine on the myocardium, and favorable effects on myocardia...
متن کاملCongestive Heart Failure
The heart is composed of two independent pumping systems, one on the left side and one on the right. The right chamber, or right atrium, of the heart relaxes and expands to fill with blood that has returned from the body. (This relaxed action causes diastolic pressure, recorded as the second and lower number when measuring blood pressure). The used blood is poor in oxygen and rich in carbon dio...
