Renal and circulatory mechanisms in congestive heart failure

Renal and circulatory factors in the edema formation of congestive heart failure.

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...

CONGESTIVE 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...

Pathophysiological Mechanisms and Drugs Leading to Decrease in Renal Function in Congestive Heart Failure

Literature review shows that elevated serum creatinine (or diminished creatinine clearance) is frequent in patients with heart failure (40%) and prognostically bad as it indicates an independently manifold increased mortality. In addition, even renal function worsening during hospitalization (increase in serum creatinine by approximately 30 micromol/L or higher) is not a rare finding (every 4 p...

Functional and circulatory renal changes in advanced heart failure.

OBJECTIVES The aim of the study was to describe the relations between heart and renal functions and to investigate whether reduced glomerular filtration rate is influenced more by reduced perfusion or venous congestion. METHODS A prospective cohort study of 101 patients (69 men, 32 women) with chronic heart failure aged 52 (49-54) (median, 95 % confidence interval) years. We analyzed the bloo...
