چکیده
BACKGROUND Efficacy and safety assessments for carperitide (alpha-human atrial natriuretic peptide) in previous clinical trials have not mentioned its limitations in practice as therapy for acute heart failure. METHODS AND RESULTS A 6-year prospective open-label registry analysis was conducted in the 'real world' of therapy for 3,777 patients with acute heart failure (male 57%, median age 73) treated with 0.085 microg . kg(-1) . min(-1) (median, interquartile 0.05-0.1) of carperitide for 65 h (median, interquartile 22-142); 51% were assessed as class III or IV according to the Killip classification; 82% of the patients were assessed as clinically improved after carperitide treatment. The efficacy limitation was related to the underlying disease (acute myocardial infarction), severity of Killip classification (Class IV), and renal function disturbance. The efficacy was significantly higher in patients with decompensated chronic heart failure (ie, cardiomyopathy, valvular diseases, and hypertensive heart disease). Incidence of adverse events was 16.9%, the most frequent being blood pressure lowering (9.5%), which occurred in the first 3 h of infusion, with 96% of patients recovering or improving without specific treatment. Logistic regression analysis revealed that factors predicting mortality (11.4%) during 7 days of follow-up were age, Killip classification, renal function disturbance, low blood pressure and use of vasopressors. CONCLUSION The clinical condition improved in 82% of patients treated with carperitide. Based on these findings, minute strategy will be established for carperitide therapy within the strata of patient characteristics that may predict the prognosis.

BACKGROUND [corrected] Acute decompensated heart failure (ADHF) is a common and highly morbid cardiovascular disorder. Diuresis is a major therapy for the reduction of congestive symptoms. However, most diuretics cause hyponatremia, which is a worsening factor of ADHF patients prognosis. The purpose of this study was to examine the efficacy and safety of tolvaptan, which is a selective vasopres...

For acute decompensated heart failure (ADHF) therapy, combination of carperitide, a human atrial natriuretic peptide, and tolvaptan, a novel vasopressin type 2 receptor antagonists, has not been used. Tolvaptan is a drug newly developed to treat volume overload in ADHF patients. Of 102 consecutive cases treated upon admission for ADHF between April and October 2012, we analyzed 51 patients trea...

BACKGROUND Diuresis is a major therapy for the reduction of congestive symptoms in acute decompensated heart failure (ADHF) patients. We previously reported the efficacy and safety of tolvaptan compared to carperitide in hospitalized patients with ADHF. There were some reports of cardio- and renal-protective effects in carperitide; therefore, the purpose of this study was to compare the long-te...

1] recently reported in their meta-analysis that carperitide infusion improved the renal function of cardiovascular surgical patients, and we feel that this notion could be expanded to medical patients, particularly with the use of carperitide. Although some studies have not been able to recommend the use of nesiritide in acute heart failure (HF) patients [2,3], more recent clinical trials have...
