Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF): rationale and design.

Heart failure (HF) affects >5 million patients in the United States, and its prevalence is increasing every year. Despite the compelling scientific evidence that angiotensin-converting enzyme inhibitors and beta-blockers reduce hospitalizations and mortality rates in patients with HF, these lifesaving therapies continue to be underused. Several studies in a variety of clinical settings have documented that a significant proportion of eligible patients with HF are not receiving treatment with these guideline-recommended, evidence-based therapies. In patients hospitalized with HF, who are at particularly high risk for re-hospitalization and death, the initiation of beta-blockers is often delayed because of concern that early initiation of these agents may exacerbate HF. Recent studies suggest that beta-blockers can be safely and effectively initiated in patients with HF before hospital discharge and that clinical outcomes are improved. The Initiation Management Predischarge Process for Assessment of Carvedilol Therapy for Heart Failure (IMPACT-HF) trial demonstrated that pre-discharge initiation of carvedilol was associated with a higher rate of beta-blocker use after hospital discharge, with no increase in hospital length of stay. In addition, there was no increase in the risk of worsening of HF. Studies of hospital-based management systems that rely on early (pre-discharge) initiation of evidence-based therapies for patients with cardiovascular disease have also found increases in post-discharge use of therapy and a reduction in the rates of mortality and hospitalization. On the basis of these pivotal studies, the Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) program is designed to improve medical care and education of hospitalized patients with HF and accelerate the initiation of evidence-based HF guideline recommended therapies by administering them before hospital discharge. A registry component, planned as the most comprehensive database of the hospitalized HF population focusing on admission to discharge and 60- to 90-day follow-up, is designed to evaluate the demographic, pathophysiologic, clinical, treatment, and outcome characteristics of patients hospitalized with HF. The ultimate aim of this program is to improve the standard of HF care in the hospital and outpatient settings and increase the use of evidence-based therapeutic strategies to save lives.

Diuretic resistance predicts mortality in patients with advanced heart failure.

BACKGROUND: In patients with chronic heart failure (CHF), diuretic requirements increase as the disease progresses. Because diuretic resistance can be overcome with escalating doses, the evaluation of CHF severity and prognosis may be incomplete without considering the intensity of therapy. METHODS: The prognostic importance of diuretic resistance (as evidenced by a high-dose requirement) was retrospectively evaluated in 1153 patients with advanced CHF who were enrolled in the Prospective Randomized Amlodipine Survival Evaluation (PRAISE). The relation of loop diuretic and angiotensin-converting enzyme inhibitor doses (defined by their median values) and other baseline characteristics to total and cause-specific mortality was determined by proportion hazards regression. RESULTS: High diuretic doses were independently associated with mortality, sudden death, and pump failure death (adjusted hazard ratios [HRs] 1.37 [P =.004], 1.39 [P =.042], and 1.51 [P =.034], respectively). Use of metolazone was an independent predictor of total mortality (adjusted HR = 1.37, P =.016) but not of cause-specific mortality. Low angiotensin-converting enzyme inhibitor dose was an independent predictor of pump failure death (adjusted HR = 2.21, P =.0005). Unadjusted mortality risks of congestion and its treatment were additive and comparable to those of established risk factors. CONCLUSIONS: The independent association of high diuretic doses with mortality suggests that diuretic resistance should be considered an indicator of prognosis in patients with chronic CHF. These retrospective observations do not establish harm or rule out a long-term benefit of diuretics in CHF, because selection bias may entirely explain the relation of prescribed therapy to death.
