ABSTRACT
OBJECTIVES: Left ventricular ejection fraction (EF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are important surrogate markers of cardiac function and wall stress. Randomized trials of heart failure (HF) have shown improvements in survival in patients with reduced EF (<40%, HFrEF) but not with preserved EF (≥50%, HFpEF) or mid-range EF (40-49%, HFmrEF). Limited information is available on the trajectory of EF in contemporary heart failure management programs (HFMPs). DESIGN: 201 HF patients consecutively enrolled 2010-2011 in the outpatient-based HFMP of Skåne University Hospital in Lund were included in the study. Probable etiology, EF, NT-proBNP and medications were assessed at baseline and 1 year after enrollment. RESULTS: HFrEF was the most common heart failure subgroup (78.1% of patients) in this HFMP, followed by HFmrEF (14.9%) and HFpEF (7.0%). The most common etiology was ischemic heart disease (IHD, 40.8%). Complete recovery of EF (>50%) was rare (14.1% of patients with HFrEF and 26.7% with HFmrEF), some degree of improvement was observed in 57.7% and 46.7% of patients. LVEF improved on average 9.1% in patients with HFrEF (p < .001) and NT-proBNP decreased from 4,202 to 2,030 pg/ml (p < .001). A similar trend was noticed for the HFmrEF group but was not statistically significant. The improvement in LVEF was consistent across subgroups with HF attributable to IHD (6.2%), idiopathic dilated cardiomyopathy (7.1%) and tachycardia-induced HF (17.5%). CONCLUSIONS: This study provides estimates of the improvement in LVEF and NT-proBNP that can be expected with contemporary management across subgroups of HF and different etiologies in a contemporary HFMP.

BACKGROUND: Psychosocial factors are important for patients undergoing heart (HTx) or lung (LTx) transplantation and for their next of kin (NoK). AIM: To describe health-related quality of life (HRQoL; patients only), anxiety, depression, stress, coping ability, and burden (NoK only) for patients and their NoK before and up to 2 years after HTx or LTx. DESIGN: Adult patients (28 hearts and 26 lungs) and their appointed NoK were surveyed with questionnaires about specific psychosocial topics when they were accepted for the transplantation waiting list and 6 months, 1 year, and 2 years after transplantation. FINDINGS: Patients' coping ability and self-perceived health were low at baseline and improved over time after transplantation. However, lung patients took longer time to recover in terms of HRQoL, depression, and stress than heart patients. Similarly, NoK of lung patients experienced a higher burden and more stress 1 year after transplantation than NoK of heart patients. CONCLUSIONS: Healthcare professionals should be aware of the psychosocial challenges patients and their NoK face in daily living and provide support both before and after heart or lung transplantation.
