Implication of modified MELD scores for postdischarge prognosis in hospitalized patients with heart failure.

We evaluated whether modified Model for End-Stage Liver Disease (MELD) scores are useful for predicting the postdischarge prognosis in hospitalized patients with heart failure (HF) who are discharged alive. The MELD-XI and MELD-Na scores were calculated at discharge for a total of 1156 patients in the HIJ-HF II study. We also studied 3 groups on the basis of the left ventricular ejection fraction (LVEF): the HFrEF (LVEF < 40%), HFmrEF (LVEF 40-49%) and HFpEF (LVEF ≥ 50%) groups. The primary outcome was all-cause mortality, and the secondary outcome was rehospitalization due to worsening HF. The median MELD-XI and MELD-Na scores were 12 and 14, respectively. After a median follow-up of 19 months, there were significantly higher rates of all-cause mortality in patients with MELD-XI scores ≥ 12 than in those with MELD-XI scores < 12; there were also higher rates of all-cause mortality in patients with MELD-Na scores ≥ 14 than in those with MELD-Na scores < 14 (both log-rank p < 0.001). The cumulative incidence function based on a competing risks model showed a higher rate of rehospitalization due to worsening HF in patients with MELD-XI scores ≥ 12 than in those with MELD-XI scores < 12 and a higher rate of rehospitalization due to worsening HF in those with MELD-Na scores ≥ 14 than in those with MELD-Na scores < 14 (both Gray's test p < 0.001). The adjusted hazard ratios (HRs) of all-cause mortality for patients with MELD-XI scores ≥ 12 and those with MELD-Na scores ≥ 14 were 2.07 [95% confidence interval (CI) 1.25-3.44] and 2.79 [95% CI 1.63-4.79], respectively, in the HFrEF group; however, the HRs were not significant in the HFmrEF or HFpEF groups. Thus, MELD-XI and MELD-Na scores may be useful for predicting prognosis in hospitalized HF patients who are discharged alive, especially for those in the HFrEF group.

Adverse Drug Reactions in Japanese Patients with End-Stage Heart Failure Receiving Continuous Morphine Infusion: A Single-Center Retrospective Cohort Study.

BACKGROUND: Opioids have been reported to be effective for refractory dyspnea in patients with advanced heart failure (HF) in the palliative care setting. OBJECTIVE: The aim of this study was to evaluate the incidence of adverse drug reactions (ADRs) and their relationship with morphine dose/duration or renal insufficiency in patients with end-stage HF receiving continuous morphine infusion. METHODS: We retrospectively studied 38 patients with end-stage HF receiving continuous intravenous or subcutaneous morphine infusion for the relief of breathlessness between 2014 and 2019 (mean age 78 years). The endpoints were nausea/vomiting, respiratory depression, and drowsiness, which are common morphine-related ADRs. RESULTS: Of 38 patients with end-stage HF receiving continuous intravenous/subcutaneous morphine infusion, 14 (37%) experienced ADRs. The median estimated glomerular filtration rate (eGFR) was lower in patients with than in those without ADRs (16 [range 9-48] vs. 41 [range 8-133], respectively; p = 0.011). The ADRs with the highest incidence were drowsiness (n = 13), nausea/vomiting (n =5), and respiratory depression (n =3). There were no differences in the maintenance dose or duration of morphine administration between patients with and without ADRs. A baseline eGFR of 32 mL/min/1.73 m2 was a good cutoff value for ADR prediction (sensitivity 86%, specificity 96%). A baseline eGFR < 32 mL/min/1.73 m2 was significantly associated with the occurrence of morphine-related ADRs (odds ratio 6.63, 95% confidence interval 1.19-37.01). CONCLUSIONS: Our results showed that 37% of patients with end-stage HF receiving continuous intravenous/subcutaneous morphine infusion experienced ADRs, especially drowsiness. Patients with eGFR < 32 mL/min/1.73 m2 were likely to experience morphine-related ADRs.

Prognostic Implication of First-Degree Atrioventricular Block in Patients With Hypertrophic Cardiomyopathy.

Background The association between first-degree atrioventricular block (AVB) and life-threatening cardiac events in patients with hypertrophic cardiomyopathy (HCM) remains unclear. This study sought to investigate whether presence of first-degree AVB was associated with HCM-related death in patients with HCM. Methods and Results We included 414 patients with HCM (mean age, 51±16 years; 64.5% men). The P-R interval was measured at the time of the initial evaluation and patients were classified into those with and without first-degree AVB, which was defined as a P-R interval ≥200 ms. HCM-related death was defined as a combined end point of sudden death or potentially lethal arrhythmic events, heart failure-related death, and stroke-related death. First-degree AVB was noted in 96 patients (23.2%) at time of enrollment. Over a median (interquartile range) follow-up period of 8.8 (4.9-12.9) years, a total of 56 patients (13.5%) experienced HCM-related deaths, including 47 (11.4%) with a combined end point of sudden death or potentially lethal arrhythmic events. In a multivariable analysis that included first-degree AVB and risk factors for life-threatening events, first-degree AVB was independently associated with an HCM-related death (adjusted hazard ratio, 2.41; 95% CI, 1.27-4.58; P=0.007), and this trend also persisted for the combined end point of sudden death or potentially lethal arrhythmic events (adjusted hazard ratio, 2.60; 95% CI, 1.28-5.27; P=0.008). Conclusions In this cohort of patients with HCM, first-degree AVB may be associated with HCM-related death, including the combined end point of sudden death or potentially lethal arrhythmic events.
