Laboratory Value-Based Innovation in Heart Failure Improves Patient Health-Related Outcomes.

BACKGROUND: NT-proBNP is emerging as a novel tool for improving management of patients with heart failure (HF). The concept of health-related outcomes as the primary endpoint for therapeutic intervention in chronic disease, such as HF, should be the focal point going forward. METHODS: We conducted a prospective real-world study in heart failure with reduced ejection fraction (HFrEF) patients. The main target was to evaluate the impact on patient's health-related outcomes of a personalized medical follow-up procedure, based on a laboratory model of risk stratification supported by NT-proBNP. One hundred and five consecutive patients admitted to the Hospital Heart-Failure unit were stratified into three groups (low, medium, and high risk) and prospective follow-ups during the 12 months post discharge. RESULTS: It was found that patients under this new approach experienced early and robust improvements in patient health-related outcomes with consistency in most domains which persisted beyond 12 months post follow-up. Improvements in health related quality of life score (HRQLS) was observed over the time of the study. After 6 months we found a significant improvement in HRQLS of 18.2% (from 76.5 ± 22.4 to 95.0 ± 15.7) and 14.4% (from 76.5 ± 22.4 to 96.3 ± 15.9) after 12 months of follow-up (p < 0.001). The highest improvements were found in the symptom severity domain where patients reported an improvement of 22.6% after 6 months and 18.9% after 12 months (p < 0.001). The lowest scores were reported in the physical domain with increase of 11.0% and 4.3% after 6 months and 12 months (p = 0.089). Psychosocial domain and the ability to carry out the activities of normal life showed improvement as well. CONCLUSIONS: Our strategy based on NT-proBNP optimizes HFrEF management and represents a major new approach for clinical laboratories to improve patient health-related outcomes in HFrEF.

Antiplatelet therapy and outcome in COVID-19: the Health Outcome Predictive Evaluation Registry.

BACKGROUND: Standard therapy for COVID-19 is continuously evolving. Autopsy studies showed high prevalence of platelet-fibrin-rich microthrombi in several organs. The aim of the study was therefore to evaluate the safety and efficacy of antiplatelet therapy (APT) in hospitalised patients with COVID-19 and its impact on survival. METHODS: 7824 consecutive patients with COVID-19 were enrolled in a multicentre international prospective registry (Health Outcome Predictive Evaluation-COVID-19 Registry). Clinical data and in-hospital complications were recorded. Data on APT, including aspirin and other antiplatelet drugs, were obtained for each patient. RESULTS: During hospitalisation, 730 (9%) patients received single APT (93%, n=680) or dual APT (7%, n=50). Patients treated with APT were older (74±12 years vs 63±17 years, p<0.01), more frequently male (68% vs 57%, p<0.01) and had higher prevalence of diabetes (39% vs 16%, p<0.01). Patients treated with APT showed no differences in terms of in-hospital mortality (18% vs 19%, p=0.64), need for invasive ventilation (8.7% vs 8.5%, p=0.88), embolic events (2.9% vs 2.5% p=0.34) and bleeding (2.1% vs 2.4%, p=0.43), but had shorter duration of mechanical ventilation (8±5 days vs 11±7 days, p=0.01); however, when comparing patients with APT versus no APT and no anticoagulation therapy, APT was associated with lower mortality rates (log-rank p<0.01, relative risk 0.79, 95% CI 0.70 to 0.94). On multivariable analysis, in-hospital APT was associated with lower mortality risk (relative risk 0.39, 95% CI 0.32 to 0.48, p<0.01). CONCLUSIONS: APT during hospitalisation for COVID-19 could be associated with lower mortality risk and shorter duration of mechanical ventilation, without increased risk of bleeding.
