PURPOSE Congestive heart failure is an important cause of patient morbidity and mortality. Although several randomized clinical trials have compared beta-blockers with placebo for treatment of congestive heart failure, a meta-analysis quantifying the effect on mortality and morbidity has not been performed recently. DATA SOURCES The MEDLINE, Cochrane, and Web of Science electronic databases w...

Although it has been demonstrated that during isotonic grip exercise patients with chronic congestive heart failure have an abnormally reduced forearm oxygen consumption resulting from a depressed forearm flood flow, there may be additional etiologies of this abnormality. To explore this possibility biopsies of the pronator teres muscle were taken in eight control subjects with normal cardiac h...

Objectives: To describe trends in hospital admissions and mortality from congestive heart failure in the elderly population aged 65 years and over in Singapore, 1991 to 1998. Design: Analysis of trends and population subgroup differences in rates of hospital admission and mortality for a primary diagnosis of congestive heart failure, classified as ICD-9, codes 428, 402.0, 402.11, and 402.91. Se...

In congestive heart failure, renal blood flow is decreased and renal vascular resistance is increased in a setting of increased activity of both the sympathetic nervous and renin-angiotensin systems. The renal vasoconstrictor response to renal nerve stimulation is enhanced. This is associated with an abnormality in the low-pass filter function of the renal vasculature wherein higher frequencies...

Congestive heart failure has become an increasingly frequent reason for hospital admission during the last 2 decades and clearly represents a major health problem. Data from the Framingham Heart Study indicate that the incidence of congestive heart failure increases with age and is higher in men than in women. Hypertension and coronary heart disease are the two most common conditions predating ...

Data from population- and clinic-based epidemiologic studies of rheumatoid arthritis patients suggest that individuals with rheumatoid arthritis are at risk for developing clinically evident congestive heart failure. Many established risk factors for congestive heart failure are over-represented in rheumatoid arthritis and likely account for some of the increased risk observed. In particular, d...

• Since the report of Deming and Lnetscher that patients with congestive heart failure excrete abnormally large amounts of a saltretaining substance in the urine, considerable attention has been focused on the role of aldosterone in congestive heart failure. Although there is a large body of evidence to demonstrate that excessive aldosterone secrelioji plays an important role in the marked Xa r...

Cheyne-Stokes respiration is a disorder characterised by recurrent central apnoeas during sleep alternating with a crescendo-decrescendo pattern of tidal volume. 2 It is often observed in patients with congestive heart failure, usually during stages 1 and 2 non-REM sleep when ventilation is under chemical-metabolic control. Patients with Cheyne-Stokes respiration usually present with the sympto...
