Plasma amino acid profiling improves predictive accuracy of adverse events in patients with heart failure

AbstractPatients with heart failure (HF) are frequently anti-coagulated with vitamin K-antagonists (VKAs). The use of long-acting VKA may be preferable for HF patients due to higher stability of plasma concentrations. However, evidence on phenprocoumon-based oral anti-coagulation (OAC) therapy in HF is scarce. The aim of this study was to assess the impact of the presence of HF on quality of phenprocoumon-based OAC and the subsequent clinical outcome. Quality of OAC therapy and the incidence of adverse events were analysed in a cohort of regular care (n = 2,011) from the multi-centre thrombEVAL study program (NCT01809015) stratified by the presence of HF. To assess the modifiability of outcome, results were compared with data from individuals receiving specialized care for anti-coagulation (n = 760). Overall, the sample comprised of 813 individuals with HF and 1,160 subjects without HF in the regular care cohort. Quality of OAC assessed by time in therapeutic range (TTR) was 66.1% (47.8%/82.8%) for patients with HF and 70.6% (52.1%/85.9%) for those without HF (p = 0.0046). Stratification for New York Heart Classification (NYHA)-class demonstrated a lower TTR with higher NYHA classes: TTRNYHA-I 69.6% (49.4%/85.6%), TTRNYHA-II 66.5% (50.1%/82.9%) and TTRNYHA-≥III 61.8% (43.1%/79.9%). This translated into a worse net clinical benefit outcome for HF (hazard ratio [HR] 1.63 [1.31/2.02]; p < 0.0001) and an increased risk of bleeding (HR 1.40 [1.04/1.89]; p = 0.028). Management in a specialized coagulation service resulted in an improvement of all, TTR (∆+12.5% points), anti-coagulation-specific and non-specific outcome of HF individuals. In conclusion, HF is an independent risk factor for low quality of OAC therapy translating into an increased risk for adverse events, which can be mitigated by specialized care.

Patients With Heart Failure

Abstract Background Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are significantly effective in reducing cardiovascular events in patients with type 2 diabetes mellitus (T2DM). However, the magnitude of the effect of SGLT-2i on cardiovascular outcomes in established heart failure (HF) patients with T2DM remains undefined. Methods We systematically searched the PubMed, Embase, Cochrane Central and Web of Science databases for articles published prior to 09 April 2020 to identify randomized controlled trials that compared SGLT-2i with placebo in patients with heart failure concomitant with T2DM. Efficacy outcomes included the composite of cardiovascular death (CVD) or hospitalization for heart failure (HHF), individual CVD, individual HHF, and all-cause mortality (ACM). Hazard ratios (HRs) with 95% confidence intervals (95% CIs) were pooled across trials by using the generic inverse variance method. Sensitivity analyses were conducted by excluding specific studies or using risk ratios (RRs) with 95% CIs as measures of the effect size. Serious adverse events served as safety outcomes. Results A total of 5 large trials comprising 6945 patients with HF and T2DM were enrolled. Pooled data demonstrated that SGLT-2i significantly reduced the risk for the primary composite outcome of CVD or HHF by 13% (HR: 0.87, 95% CI: 0.83–0.91, I2: 0%, P < 0.00001) in patients with HF concomitant with T2DM. Similarly, the use of SGLT-2i was associated with a statistically significant 14% reduction in HHF (pooled HR: 0.86, 95% CI: 0.81–0.91, I2: 0%, P < 0.00001) and a 10% reduction in ACM (pooled HR: 0.90, 95% CI: 0.86–0.96, I2: 16%, P < 0.0005) but was not significantly associated with a reduction in CVD (HR: 0.91, 95% CI: 0.81–1.02, I2: 60%, P = 0.11). Sensitivity analyses indicted consistent results. Compared with placebo plus standard care, the SGLT-2i group had a lower proportion of serious adverse events (weighted proportions: 44.3% vs 50.3%; RR 0.88, 95% CI 0.82–0.95, I2: 22%, p = 0∙006). Conclusions SGLT-2i significantly reduced the risk of HHF and ACM in a broad range of HF patients concomitant with T2DM. Compared with standard care, SGLT-2i plus standard therapy was associated with a reduction in serious adverse events.
