Rationale and design of the ESC Heart Failure III Registry - Implementation and discovery.
AIMS: Heart failure outcomes remain poor despite advances in therapy. The European Society of Cardiology Heart Failure III Registry (ESC HF III Registry) aims to characterize HF clinical features and outcomes and to assess implementation of guideline-recommended therapy in Europe and other ESC affiliated countries. METHODS: Between 1 November 2018 and 31 December 2020, 10 162 patients with chronic or acute/worsening HF with reduced, mildly reduced, or preserved ejection fraction were enrolled from 220 centres in 41 European or ESC affiliated countries. The ESC HF III Registry collected data on baseline characteristics (hospital or clinic presentation), hospital course, diagnostic and therapeutic decisions in hospital and at the clinic visit; and on outcomes at 12-month follow-up. These data include demographics, medical history, physical examination, biomarkers and imaging, quality of life, treatments, and interventions - including drug doses and reasons for non-use, and cause-specific outcomes. CONCLUSION: The ESC HF III Registry will provide comprehensive and unique insight into contemporary HF characteristics, treatment implementation, and outcomes, and may impact implementation strategies, clinical discovery, trial design, and public policy

Accuracy of the ABC/2 score for intracerebral hemorrhage: systematic review and analysis of MISTIE, CLEAR-IVH, and CLEAR III
Background and Purpose: The ABC/2 score estimates intracerebral hemorrhage (ICH) volume, yet validations have been limited by small samples and inappropriate outcome measures. We determined accuracy of the ABC/2 score calculated at a specialized reading center (RC-ABC) or local site (site-ABC) versus the reference-standard computed tomography–based planimetry (CTP).
p>Methods:In Minimally Invasive Surgery Plus Recombinant Tissue-Type Plasminogen Activator for Intracerebral Hemorrhage Evacuation-II (MISTIE-II), Clot Lysis Evaluation of Accelerated Resolution of Intraventricular Hemorrhage (CLEAR-IVH) and CLEAR-III trials. ICH volume was prospectively calculated by CTP, RC-ABC, and site-ABC. Agreement between CTP and ABC/2 was defined as an absolute difference up to 5 mL and relative difference within 20%. Determinants of ABC/2 accuracy were assessed by logistic regression.
Results: In 4369 scans from 507 patients, CTP was more strongly correlated with RC-ABC (r2=0.93) than with site-ABC (r2=0.87). Although RC-ABC overestimated CTP-based volume on average (RC-ABC, 15.2 cm3; CTP, 12.7 cm3), agreement was reasonable when categorized into mild, moderate, and severe ICH (κ=0.75; P
Conclusions: ABC/2 scores at local or central sites are sufficiently accurate to categorize ICH volume and assess eligibility for the CLEAR-III and MISTIE III studies and moderately accurate for change in ICH volume. However, accuracy decreases with large, irregular, or lobar clots.</p

Recent clinical trials with omapatrilat: new developments.
Omapatrilat belongs to the vasopeptidase inhibitors, ie, drugs that possess the ability to inhibit simultaneously the membrane-bound zinc metalloproteases, angiotensin-converting enzyme (ACE), and the neutral endopeptidase EC 3.4.24.11 (NEP). Omapatrilat was targeted to treat patients with hypertension and congestive heart failure. The preclinical and early clinical studies conducted with omapatrilat were very promising. Indeed, omapatrilat appeared to be a very potent antihypertensive agent with very favorable effects on cardiac function in heart failure patients. In contrast to these early studies, the large clinical trials were more disappointing. The results of the OCTAVE trial confirmed the antihypertensive efficacy of omapatrilat, but at the price of an angioedema rate more than threefold higher than that of an ACE inhibitor in the overall population (2.17% vs 0.68%), and close to fourfold higher in the black population. In OVERTURE, a large randomized control trial in heart failure, angioedema was also more common with omapatrilat, but the incidence was much lower (0.8% with omapatrilat vs 0.5% with enalapril). However, omapatrilat was not convincingly superior to the ACE inhibitor. Because angioedema is probably a class side effect of vasopeptidase inhibitors, the higher incidence of this potentially life-threatening complication with omapatrilat has likely stopped the development of this new class of agents. The future of vasopeptidase inhibitors will depend on the ability to improve the risk/benefit ratio either by developing agents that produce less angioedema, or by defining more precisely a high-risk population that could take advantage of dual ACE/NEP inhibition
