Congestive heart failure (CHF) afflicts nearly 5 million persons in the United States. An estimated 550,000 new cases of heart failure are diagnosed annually. 1 Roughly equal numbers of men and women have CHF. The incidence of heart failure is approximately 1 per 100 for persons older than 65 years. 2 Heart failure results in a tremendous economic burden. CHF now represents the most common discharge diagnosis in patients older than 65 years. 3 The prognosis of this condition in the absence of optimal treatment remains poor. Only 50% of CHF patients survive for 5 years after diagnosis. 4 References: Hunt SA, Baker DW, Chin MH, et al.

Heart failure currently affects 4.79 million persons in the United States alone, 1 and this number is expected to rise to 10 million by 2037. 2 Approximately 550,000 new cases of heart failure are diagnosed each year. One reason for the increase in heart failure is old age. Risk of sudden cardiac death is 6 to 9 times higher in the heart failure population. 1 The prevalence of heart failure increases with age, affecting 10% of persons aged 70 years and older. 3 References: American Heart Association. 2002 Heart and Stroke Statistical Update.

Data from the Acute Decompensated Heart Failure Registry (ADHERE) and Euro Heart Failure Survey in over 120,000 consecutive patients showed that over 75% of the admissions for heart failure are due to worsening of chronic heart failure. About 20% of the admissions are due to newly diagnosed heart failure cases (e.g., post-MI, hypertensive episode on a non-compliant ventricle, etc.) and only 2% of admissions are seen in patients with low output state (or advanced/end-stage heart failure). This is extremely important, as many clinicians believe that a low output state is a very common reason for admissions. Although these patients comprise only 2% of the population, they are often extremely sick and this is the population the heart failure specialists are being consulted on, contributing to the biased view that these patients represent the majority of admissions, when in fact they are a distinct minority.
Most Common IV Medications All Enrolled Discharges (N = 105,388) October 2001 –January 2004 The use of IV vasoactive medications is shown on this slide. IV diuretics are used in 88% of patients admitted with ADHF. Data on file, Scios Inc.

In VMAC, the beneficial effect of nesiritide on dyspnea at 3 hours was significant compared with placebo, in all subjects ( P = 0.034) as well as in the catheterized stratum ( P = 0.030).
