Multicenter StudyMidregion prohormone adrenomedullin and prognosis in patients presenting with acute dyspnea: results from the BACH (Biomarkers in Acute Heart Failure) trial.
The aim of this study was to determine the prognostic utility of midregion proadrenomedullin (MR-proADM) in all patients, cardiac and noncardiac, presenting with acute shortness of breath. ⋯ MR-proADM identifies patients with high 90-day mortality and adds prognostic value to natriuretic peptides in patients presenting with acute shortness of breath. Serial measurement of this biomarker may also prove useful for monitoring, although further studies will be required. (Biomarkers in Acute Heart Failure [BACH]; NCT00537628).

Randomized Controlled Trial Multicenter Study Comparative StudyEffect of lenient versus strict rate control on cardiac remodeling in patients with atrial fibrillation data of the RACE II (RAte Control Efficacy in permanent atrial fibrillation II) study.
The aim of this study was to evaluate echocardiographic remodeling in permanent atrial fibrillation (AF) patients treated with either lenient or strict rate control. ⋯ Female sex, not lenient rate control, seemed to be associated with significant adverse cardiac remodeling in patients with permanent AF such as those enrolled in the RACE II study. (RAte Control Efficacy in Permanent Atrial Fibrillation [RACE II]; NCT00392613).

Randomized Controlled Trial Comparative StudyResults of low-dose human atrial natriuretic peptide infusion in nondialysis patients with chronic kidney disease undergoing coronary artery bypass grafting: the NU-HIT (Nihon University working group study of low-dose HANP Infusion Therapy during cardiac surgery) trial for CKD.
The purpose of this comparative study is to prove the efficacy of the human atrial natriuretic peptide (hANP) in patients with chronic kidney disease (CKD) undergoing coronary artery bypass graft surgery (CABG). ⋯ In the post-operative acute stage, carperitide showed cardiorenal protective effects that prevented post-operative cardiac events and initiation of dialysis. Thus, perioperative infusion of low-dose carperitide may have a significant role in management of patients with renal dysfunction undergoing on-pump CABG. (Effectiveness of hANP for Cardiac Surgery in Patients With Moderate to Severe Preoperative Renal Dysfunction Without Dialysis [NU-HIT for CRF]; UMIN000001462).

Comparative StudyDiastolic dysfunction in patients undergoing cardiac surgery: a pathophysiological mechanism underlying the initiation of new-onset post-operative atrial fibrillation.
Our goal was to investigate whether left ventricular (LV) diastolic dysfunction was an important pathophysiological mechanism underlying the initiation of new-onset post-operative atrial fibrillation (POAF). ⋯ LV diastolic dysfunction is a powerful, independent predisposing substrate for the initiation of POAF. Evaluation may be useful during risk stratification of patients undergoing cardiac surgery.
