Efficiency and Safety of Prolonged Levosimendan Infusion in Patients with Acute Heart Failure
Background. Levosimendan is an inotropic drug with unique pharmacological advantages in patients with acute heart failure. Scope of this study is to determine whether longer infusion patterns without the hypotension-inducing loading dose could justify an effective and safe alternative approach. Methods. 70 patients admitted to the emergencies with decompensated chronic heart failure received intravenously levosimendan without a loading dose up to 72 hours. Clinical parameters, BNP (Brain Natriuretic Peptide) and signal-averaged-ECG data (SAECG) were recorded up to 72 hours. Results. The 48-hour group demonstrated a statistically significant BNP decrease (P < .001) after 48 hours, which also maintained after 72 hours. The 72-hour group demonstrated a bordeline decrease of BNP after 48 hours (P = .039), necessitating an additional 24-hour infusion to achieve significant reduction after 72 hours (P < .004). SAECG data demonstrated a statistically significant decrease after 72 hours (P < .04). Apart from two deaths due to advanced heart failure, no major complications were observed. Conclusion. Prolonged infusion of levosimendan without a loading dose is associated with an acceptable clinical and neurohumoral response

Digoxin Use and Outcomes in Patients With Heart Failure With Reduced Ejection Fraction.
BACKGROUND: Heart failure is a leading cause for hospital readmission. Digoxin use may lower this risk in patients with heart failure with reduced ejection fraction (HFrEF), but data on contemporary patients receiving other evidence-based therapies are lacking. METHODS: Of the 11,900 patients with HFrEF (ejection fraction ≤45%) in Medicare-linked OPTIMIZE-HF, 8401 were not on digoxin, of whom 1571 received discharge prescriptions for digoxin. We matched 1531 of these patients with 1531 not receiving digoxin by propensity scores for digoxin use. The matched cohort (n = 3062; mean age, 76 years; 44% women; 14% African American) was balanced on 52 baseline characteristics. We assembled a second matched cohort of 2850 patients after excluding those with estimated glomerular filtration rate <15 mL/min/1.73 m2 and heart rate <60 beats/min. Hazard ratios (HRs) and 95% confidence intervals (CIs) for digoxin-associated outcomes were estimated in the matched cohorts. RESULTS: Among the 3062 matched patients, digoxin use was associated with a significantly lower risk of heart failure readmission at 30 days (HR, 0.74; 95% CI, 0.59-0.93), 1 year (HR, 0.81; 95% CI, 0.72-0.92), and 6 years (HR, 0.90; 95% CI 0.81-0.99). The association with all-cause readmission was significant at 1 and 6 years but not 30 days. There was no association with mortality. Similar associations were observed among the 2850 matched patients without bradycardia or renal insufficiency. CONCLUSIONS: Among hospitalized older patients with HFrEF receiving contemporary treatments for heart failure, digoxin use is associated with a lower risk of hospital readmission but not all-cause mortality
Initiation of Anti-Hypertensive Drugs and Outcomes in Patients with Heart Failure with Reduced Ejection Fraction.
BACKGROUND: In patients with heart failure with reduced ejection fraction (HFrEF) and hypertension, systolic blood pressure is recommended to be maintained below 130 mmHg, although this has not been shown to be associated with improved outcomes. We examined the association between anti-hypertensive drug initiation and outcomes in patients with HFrEF. METHODS: In the Medicare-linked OPTIMIZE-HF, 7966 patients with HFrEF (ejection fraction ≤40%) without renal failure were not receiving anti-hypertensive drugs before hospitalization, of whom 692 received discharge prescriptions for those drugs (thiazides and calcium channel blockers). We assembled a propensity score-matched cohort of 687 pairs of patients initiated and not initiated on anti-hypertensive drugs, balanced on 38 baseline characteristics. Hazard ratios (HR) and 95% confidence intervals (CIs) for outcomes associated with anti-hypertensive drug initiation were estimated in the matched cohort. RESULTS: Matched patients (n = 1374) had a mean age of 74 years, 41% were female, 17% were African-American, 66% were discharged on renin-angiotensin system inhibitors and beta blockers, and 10% on aldosterone antagonists. During 6 (median 2.5) years of follow-up, 70% of the patients died and 53% had heart failure readmission. Anti-hypertensive drug initiation was not significantly associated with all-cause mortality (HR, 0.95; 95% CI, 0.83-1.07) or heart failure readmission (HR, 0.93; 95% CI, 0.80-1.07). Similar associations were observed during 30 days and 12 months of follow-up. CONCLUSIONS: Among hospitalized older patients with HFrEF receiving contemporary treatments for heart failure, initiation of an anti-hypertensive drug was not associated with a lower risk of all-cause mortality or hospital readmission
