    • BACKGROUND: Studies in experimental models and preliminary clinical experience suggested a possible therapeutic role for the soluble tumor necrosis factor antagonist etanercept in heart failure. METHODS AND RESULTS: Patients with New York Heart Association class II to IV chronic heart failure and a left ventricular ejection fraction < or =0.30 were enrolled in 2 clinical trials that differed only in the doses of etanercept used. In RECOVER, patients received placebo (n=373) or subcutaneous etanercept in doses of 25 mg every week (n=375) or 25 mg twice per week (n=375). In RENAISSANCE, patients received placebo (n=309), etanercept 25 mg twice per week (n=308), or etanercept 25 mg 3 times per week (n=308). The primary end point of each individual trial was clinical status at 24 weeks. Analysis of the effect of the 2 higher doses of etanercept on the combined outcome of death or hospitalization due to chronic heart failure from the 2 studies was also planned (RENEWAL). On the basis of prespecified stopping rules, both trials were terminated prematurely owing to lack of benefit. Etanercept had no effect on clinical status in RENAISSANCE (P=0.17) or RECOVER (P=0.34) and had no effect on the death or chronic heart failure hospitalization end point in RENEWAL (etanercept to placebo relative risk=1.1, 95% CI 0.91 to 1.33, P=0.33). CONCLUSIONS: The results of RENEWAL rule out a clinically relevant benefit of etanercept on the rate of death or hospitalization due to chronic heart failure.

  • Effect of candesartan on cause-specific mortality in heart failure patients: the Candesartan in Heart failure Assessment of Reduction in Mortality and morbidity (CHARM) program
  • 2004
  • Ingår i: Circulation. - 1524-4539. ; 110:15, s. 2180-3
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with heart failure are at increased risk of sudden death and death attributed to progressive pump failure. We assessed the effect of candesartan on cause-specific mortality in patients enrolled in the Candesartan in Heart failure Assessment of Reduction in Mortality and morbidity (CHARM) program. METHODS AND RESULTS: The CHARM program consisted of 3 component trials that enrolled patients with symptomatic heart failure: CHARM-Alternative (n=2028; LVEF<=40% [corrected] and ACE intolerant), CHARM-Added (n=2548; LVEF<=40%, [corrected] already on ACE inhibitors), and CHARM-Preserved (n=3023; LVEF >40%). Patients were randomized to candesartan, titrated to 32 mg QD, or placebo and were followed up for a median of 37.7 months. All deaths were reviewed by a blinded adjudication committee and categorized according to prespecified definitions on the basis of a narrative and source documentation. The number and rate of deaths by cause were calculated for each of the component trials and the overall program. Of all the patients, 8.5% died suddenly, and 6.2% died of progressive heart failure. Candesartan reduced both sudden death (HR 0.85 [0.73 to 0.99], P=0.036) and death from worsening heart failure (HR 0.78 [0.65 to 0.94], P=0.008). These reductions were most apparent in the patients with LVEF<=40% [corrected]. CONCLUSIONS: Candesartan reduced sudden death and death from worsening heart failure in patients with symptomatic heart failure, although this reduction was most apparent in patients with systolic dysfunction.

  • Mortality and morbidity reduction with Candesartan in patients with chronic heart failure and left ventricular systolic dysfunction: results of the CHARM low-left ventricular ejection fraction trials
  • 2004
  • Ingår i: Circulation. - 1524-4539. ; 110:17, s. 2618
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with symptomatic chronic heart failure (CHF) and reduced left ventricular ejection fraction (LVEF) have a high risk of death and hospitalization for CHF deterioration despite therapies with angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, and even an aldosterone antagonist. To determine whether the angiotensin-receptor blocker (ARB) candesartan decreases cardiovascular mortality, morbidity, and all-cause mortality in patients with CHF and depressed LVEF, a prespecified analysis of the combined Candesartan in Heart Failure Assessment of Reduction in Mortality and morbidity (CHARM) low LVEF trials was performed. CHARM is a randomized, double-blind, placebo-controlled, multicenter, international trial program. METHODS AND RESULTS: New York Heart Association (NYHA) class II through IV CHF patients with an LVEF of < or =40% were randomized to candesartan or placebo in 2 complementary parallel trials (CHARM-Alternative, for patients who cannot tolerate ACE inhibitors, and CHARM-Added, for patients who were receiving ACE inhibitors). Mortality and morbidity were determined in 4576 low LVEF patients (2289 candesartan and 2287 placebo), titrated as tolerated to a target dose of 32 mg once daily, and observed for 2 to 4 years (median, 40 months). The primary outcome (time to first event by intention to treat) was cardiovascular death or CHF hospitalization for each trial, with all-cause mortality a secondary end point in the pooled analysis of the low LVEF trials. Of the patients in the candesartan group, 817 (35.7%) experienced cardiovascular death or a CHF hospitalization as compared with 944 (41.3%) in the placebo group (HR 0.82; 95% CI 0.74 to 0.90; P<0.001) with reduced risk for both cardiovascular deaths (521 [22.8%] versus 599 [26.2%]; HR 0.84 [95% CI 0.75 to 0.95]; P=0.005) and CHF hospitalizations (516 [22.5%] versus 642 [28.1%]; HR 0.76 [95% CI 0.68 to 0.85]; P<0.001). It is important to note that all-cause mortality also was significantly reduced by candesartan (642 [28.0%] versus 708 [31.0%]; HR 0.88 [95% CI 0.79 to 0.98]; P=0.018). No significant heterogeneity for the beneficial effects of candesartan was found across prespecified and subsequently identified subgroups including treatment with ACE inhibitors, beta-blockers, an aldosterone antagonist, or their combinations. The study drug was discontinued because of adverse effects by 23.1% of patients in the candesartan group and 18.8% in the placebo group; the reasons included increased creatinine (7.1% versus 3.5%), hypotension (4.2% versus 2.1%), and hyperkalemia (2.8% versus 0.5%), respectively (all P<0.001). CONCLUSIONS: Candesartan significantly reduces all-cause mortality, cardiovascular death, and heart failure hospitalizations in patients with CHF and LVEF < or =40% when added to standard therapies including ACE inhibitors, beta-blockers, and an aldosterone antagonist. Routine monitoring of blood pressure, serum creatinine, and serum potassium is warranted.

  • Heart failure with preserved left ventricular systolic function; epidemiology, clinical characteristics, and prognosis
  • 2004
  • Ingår i: Journal of the American College of Cardiology. - 0735-1097. ; 43:3, s. 317
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent cross-sectional, population-based echocardiographic studies show that about half of all patients with heart failure have preserved left ventricular systolic function (HF-PSF). Cohort studies of hospitalized patients show a smaller proportion of HF-PSF. Compared to those with reduced systolic function, patients with HF-PSF are more often female, older, less likely to have coronary artery disease, and more likely to have hypertension. Patients with HF-PSF are less symptomatic and receive different pharmacologic therapy than patients with reduced systolic function. Morbidity and mortality rates in patients with HF-PSF are high but not quite as high as in patients with reduced systolic function. Though much has recently been learned about the syndrome of HF-PSF, many questions remain to be answered, not least how it should be treated.

  • Effect of candesartan on New York Heart Association functional class. Results of the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) programme
  • 2004
  • Ingår i: European heart journal. - 0195-668X. ; 25:21, s. 1920-6
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To evaluate the effect of the angiotensin receptor blocker candesartan on New York Heart Association (NYHA) functional class in a broad spectrum of patients with chronic heart failure (CHF). METHODS AND RESULTS: Patients in the CHARM Programme with symptomatic CHF were randomized to placebo (n=3796) or candesartan (n=3803) and followed for a median of 38 months. NYHA class was assessed at baseline, at two weekly intervals during dose titration and 4 monthly thereafter. Patients were classified as "better", "unchanged" or "worse" at the end of the study compared to baseline. Both a simple "last visit carried forward" (LVCF) analysis and "worst rank carried forward" (WRCF) analysis (where patients who died were allocated NYHA class V) were used. In the LVCF analysis, compared to placebo, more candesartan patients improved (35.4% versus 32.5%) and fewer worsened (9.0% versus 10.3%) in NYHA class (p=0.003). The WRCF analysis also showed a better overall change in NYHA class with candesartan compared to placebo. There was no heterogeneity in the response to candesartan between the CHARM component trials. CONCLUSIONS: Candesartan improves NYHA functional class to a similar extent to other proven treatments for CHF when added to these other treatments.
