Aims: Haemodynamic monitoring using implantable pressure sensors reduces the risk of heart failure (HF) hospitalizations. Patient self‐management (PSM) of haemodynamics in HF has the potential to personalize treatment, increase adherence, and reduce the risk of worsening HF, while lowering clinicians' burden. Methods and results: The VECTOR‐HF I and IIa studies are prospective, single‐arm, open‐label clinical trials assessing safety, usability and performance of left atrial pressure (LAP)‐guided HF management using PSM in New York Heart Association class II and III HF patients. Physician‐prescribed LAP thresholds trigger patient self‐adjustment of diuretics. Primary endpoints include the ability to perform LAP measurements and transmit data to the healthcare provider (HCP) interface and the patient guidance application, and safety outcomes. This is an interim analysis of 13 patients using the PSM approach. Over 12 months, no procedure‐ or device‐related major adverse cardiovascular or neurological events were observed, and there were no failures to obtain measurements from the sensor and transmit the data to the HCP interface and the patient guidance application. Patient adherence was 91.4%. Using PSM, annualized HF hospitalization rate significantly decreased compared to a similar period prior to PSM utilization (0 admissions vs. 0.69 admissions over 11.84 months, p = 0.004). At 6 months, 6‐min walk test distance and the Kansas City Cardiomyopathy Questionnaire overall summary score demonstrated significant improvement. Conclusions: Interim findings suggest that PSM using a LAP monitoring system is feasible and safe. PSM is associated with high patient adherence, potentially improving HF patients' functional status, quality of life, and limiting HF hospitalizations. [ABSTRACT FROM AUTHOR]

BACKGROUND: Cardiogenic shock is a morbid complication of heart disease that claims the lives of more than 1 in 3 patients presenting with this syndrome. Supporting a unique collaboration across clinical specialties, federal regulators, payors, and industry, the American Heart Association volunteers and staff have launched a quality improvement registry to better understand the clinical manifestations of shock phenotypes, and to benchmark the management patterns, and outcomes of patients presenting with cardiogenic shock to hospitals across the United States. METHODS: Participating hospitals will enroll consecutive hospitalized patients with cardiogenic shock, regardless of etiology or severity. Data are collected through individual reviews of medical records of sequential adult patients with cardiogenic shock. The electronic case record form was collaboratively designed with a core minimum data structure and aligned with Shock Academic Research Consortium definitions. This registry will allow participating health systems to evaluate patientlevel data including diagnostic approaches, therapeutics, use of advanced monitoring and circulatory support, processes of care, complications, and in-hospital survival. Participating sites can leverage these data for onsite monitoring of outcomes and benchmarking versus other institutions. The registry was concomitantly designed to provide a high-quality longitudinal research infrastructure for pragmatic randomized trials as well as translational, clinical, and implementation research. An aggregate deidentified data set will be made available to the research community on the American Heart Association's Precision Medicine Platform. On March 31, 2022, the American Heart Association Cardiogenic Shock Registry received its first clinical records. At the time of this submission, 100 centers are participating. CONCLUSIONS: The American Heart Association Cardiogenic Shock Registry will serve as a resource using consistent data structure and definitions for the medical and research community to accelerate scientific advancement through shared learning and research resulting in improved quality of care and outcomes of shock patients.

Aims: Patients with heart failure usually have several other medical conditions that might alter the effects of interventions. We investigated whether the burden of comorbidity modified the clinical response to cardiac resynchronization therapy (CRT). Methods and results: Original patient‐level data from eight randomized trials exploring the effects of CRT versus no CRT were pooled (BLOCK‐HF, MIRACLE, MIRACLE‐ICD, MIRACLE‐ICD II, RAFT, COMPANION, MADIT‐CRT and REVERSE). A prior history of the following comorbidities was considered: episodic or persistent atrial fibrillation (n = 920), coronary artery disease (n = 3732), diabetes (n = 2171), and hypertension (n = 3353). Patients were classified into three groups based on the number of comorbidities: 0, 1–2, or ≥3. The outcomes of interest were time to all‐cause mortality and time to the composite outcome of heart failure hospitalization (HFH) or all‐cause mortality. Outcomes were evaluated within each comorbidity group using a Bayesian hierarchical Weibull survival regression model. Of 6324 patients, 970 (15%) had no comorbidities, 4052 (64%) had 1–2 and 1302 (21%) had ≥3 comorbidities. The adjusted hazard ratio (aHR) for CRT versus no CRT for all‐cause mortality in the overall cohort was 0.79 (95% credible interval [CI] 0.68–0.93) (p = 0.010); for no comorbidities the aHR was 0.54 (95% CI 0.34–0.86), for 1–2 comorbidities was 0.81 (95% CI 0.67–0.97) and for ≥3 comorbidities was 0.83 (95% CI 0.64–1.07) (no significant interaction between CRT and comorbidity burden: p = 0.13). For the endpoint of HFH or all‐cause mortality, the aHR for the overall cohort was 0.74 (95% CI 0.65–0.84) (p = 0.001), for no comorbidities was 0.69 (95% CI 0.50–0.94), for 1–2 comorbidities was 0.77 (95% CI 0.66–0.90) and for ≥3 comorbidities was 0.68 (95% CI 0.55–0.82) (no significant interaction between CRT and comorbidity burden: p = 0.081). Conclusion: In a meta‐analysis of patient‐level data from eight major trials, the totality of evidence suggests that CRT reduces HFH and/or all‐cause mortality even when several comorbid diseases are present. Clinical Trial Registration: NCT00271154, NCT00251251, NCT00267098, NCT00180271. [ABSTRACT FROM AUTHOR]

Introduction: Cardiac implantable electrical devices are able to affect kidney function through hemodynamic improvements. The cardiac contractility modulation (CCM) is a device-based therapy option for patients with symptomatic chronic heart failure (HF) despite optimized medical treatment. The long-term cardiorenal interactions for CCM treated patients are yet to be described. Methods: CCM recipients (n = 187) from the Mannheim Cardiac Contractility Modulation Observational Study (MAINTAINED) were evaluated in the long-term (up to 60 months) for changes in serum creatinine, estimated glomerular filtration rate (eGFR), other surrogate markers of kidney function, and the chronic kidney disease (CKD) stage distribution. With regard to kidney function at baseline, the patients were furthermore grouped to either advanced CKD (aCKD, CKD stage ≥3, eGFR≤59 mL/min/1.73 m2, n = 107) or preserved kidney function and mild CKD (pCKD, CKD stages 1–2, eGFR≥60 mL/min/1.73 m2, n = 80). The groups were compared for differences regarding kidney function, New York Heart Association classification (NYHA), biventricular systolic function, HF hospitalizations and other parameters in the long-term (60 months). Results: CKD stage distribution remained stable during the entire follow-up (p = 0.65). An increase in serum creatinine (1.47 ± 1 vs. 1.6±1 mg/dL) with a corresponding decline of eGFR (58.2 ± 23.4 vs. 54.2 ± 24.4 mL/min/1.73 m2, both p < 0.05) were seen after 60 months but not before for the total cohort, which was only significant in pCKD patients in terms of group comparison. Mean survival (54.3 ± 1.3 vs. 55.3 ± 1.2 months, p = 0.53) was comparable in both groups. Improvements in NYHA (3.11 ± 0.46 vs. 2.94 ± 0.41–2.28 ± 0.8 vs. 1.94 ± 0.6) and LVEF (24.8 ± 7.1 vs. 22.9 ± 6.6–31.1 ± 11.4 vs. 35.5 ± 11.1%) were likewise similar after 60 months (both p < 0.05). The aCKD patients suffered from more HF hospitalizations and ventricular tachycardias during the entire follow-up period (both p < 0.05). Conclusions: The kidney function parameters and CKD stage distribution might remain stable in CCM treated HF patients in the long-term, who experience improvements in LVEF and functional status, regardless of their kidney function before. An impaired kidney function might be associated with further cardiovascular comorbidities and more advanced HF before CCM, and could be an additional risk factor of HF complications afterward.

Background: Whether transcatheter mitral-valve repair improves outcomes in patients with heart failure and functional mitral regurgitation is uncertain., Methods: We conducted a randomized, controlled trial involving patients with heart failure and moderate to severe functional mitral regurgitation from 30 sites in nine countries. The patients were assigned in a 1:1 ratio to either transcatheter mitral-valve repair and guideline-recommended medical therapy (device group) or medical therapy alone (control group). The three primary end points were the rate of the composite of first or recurrent hospitalization for heart failure or cardiovascular death during 24 months; the rate of first or recurrent hospitalization for heart failure during 24 months; and the change from baseline to 12 months in the score on the Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS; scores range from 0 to 100, with higher scores indicating better health status)., Results: A total of 505 patients underwent randomization: 250 were assigned to the device group and 255 to the control group. At 24 months, the rate of first or recurrent hospitalization for heart failure or cardiovascular death was 37.0 events per 100 patient-years in the device group and 58.9 events per 100 patient-years in the control group (rate ratio, 0.64; 95% confidence interval [CI], 0.48 to 0.85; P = 0.002). The rate of first or recurrent hospitalization for heart failure was 26.9 events per 100 patient-years in the device group and 46.6 events per 100 patient-years in the control group (rate ratio, 0.59; 95% CI, 0.42 to 0.82; P = 0.002). The KCCQ-OS score increased by a mean (±SD) of 21.6±26.9 points in the device group and 8.0±24.5 points in the control group (mean difference, 10.9 points; 95% CI, 6.8 to 15.0; P<0.001). Device-specific safety events occurred in 4 patients (1.6%)., Conclusions: Among patients with heart failure with moderate to severe functional mitral regurgitation who received medical therapy, the addition of transcatheter mitral-valve repair led to a lower rate of first or recurrent hospitalization for heart failure or cardiovascular death and a lower rate of first or recurrent hospitalization for heart failure at 24 months and better health status at 12 months than medical therapy alone.

Background: For patients with functional mitral regurgitation (FMR) and symptomatic heart failure (HF), randomized trials of mitral transcatheter edge-to-edge repair (M-TEER) have produced conflicting results., Objectives: This study sought to assess the impact of M-TEER on hospitalization rates, and explore the effects of M-TEER on patients who did or did not have a history of recent HF hospitalizations before undergoing M-TEER., Methods: RESHAPE-HF2 (Randomized Investigation of the MitraClip Device in Heart Failure: 2nd Trial in Patients with Clinically Significant Functional Mitral Regurgitation) included patients with symptomatic HF and moderate to severe FMR (mean effective regurgitant orifice area 0.25 cm 2 ; 14% >0.40 cm 2 , 23% <0.20 cm 2 ) and showed that M-TEER reduced recurrent HF hospitalizations with and without the addition of cardiovascular (CV) death and improved quality of life. We now report the results of prespecified analyses on hospitalization rates and for the subgroup of patients (n = 333) with a HF hospitalization in the 12 months before randomization., Results: At 24 months, the time to first event of CV death or HF hospitalization (HR: 0.65; 95% CI: 0.49-0.85; P = 0.002), the rate of recurrent CV hospitalizations (rate ratio [RR]: 0.75; 95% CI: 0.57-0.99; P = 0.046), the composite rate of recurrent CV hospitalizations and all-cause mortality (RR: 0.74; 95% CI: 0.57-0.95; P = 0.017), and of recurrent CV death and CV hospitalizations (RR: 0.76; 95% CI: 0.58-0.99; P = 0.040), were all lower in the M-TEER group. The RR of recurrent hospitalizations for any cause was 0.82 (95% CI: 0.63-1.07; P = 0.15) for patients in the M-TEER group vs control group patients. Patients randomized to M-TEER lost fewer days due to death or HF hospitalization (13.9% [95% CI: 13.0%-14.8%] vs 17.4% [95% CI: 16.4%-18.4%] of follow-up time; P < 0.0001, and 1,067 vs 1,776 total days lost; P < 0.0001). Patients randomized to M-TEER also had better NYHA functional class at 30 days and at 6, 12, and 24 months of follow-up (P < 0.0001). A history of HF hospitalizations before randomization was associated with worse outcomes and greater benefit with M-TEER on the rate of the composite of recurrent HF hospitalizations and CV death (P interaction  = 0.03) and of recurrent HF hospitalizations within 24 months (P interaction  = 0.06)., Conclusions: These results indicate that a broader application of M-TEER in addition to optimal guideline-directed medical therapy should be considered among patients with symptomatic HF and moderate to severe FMR, particularly in those with a history of a recent hospitalization for HF., Competing Interests: Funding Support and Author Disclosures Prof Ponikowsaki has received a grant from Vifor Pharma; has received consulting fees and/or honoraria from Boehringer Ingelheim, AstraZeneca, Vifor Pharma, Servier, Novartis, Berlin Chemie, Bayer, Abbott Vascular, Novo Nordisk, Pharmacosmos, Moderna, Pfizer, and Abbott Vascular; and has received fees for trial committee work from Boehringer Ingelheim, Vifor Pharma, Novo Nordisk, Pharmacosmos, and Moderna.

Over the past decade, the field of heart failure (HF) has witnessed remarkable progress in drug development, resulting in the approval of numerous groundbreaking drugs by the U.S. Food and Drug Administration. To address some of these challenges, the U.S. Food and Drug Administration has issued guidance documents that have been critical in contemporary HF drug development; however, there are still many challenges in need of investigation. This article leverages efforts of the Heart Failure Collaboratory and the scientific community to discuss the critical need for innovative trial designs, important concepts in clinical trials in the modern era, and the utilization of big data to accelerate HF drug development. At this inflection point in HF drug development, it is imperative that, as a global scientific community, we foster increased collaboration among researchers, clinicians, patients, and regulatory bodies. Only through such unified efforts can we navigate the complexities of HF, accelerate the development process, and ultimately deliver effective therapies that transform patient outcomes., Competing Interests: Funding Support and Author Disclosures Dr Januzzi has a board position with Imbria Pharma; has received grant support from Abbott, Applied Therapeutics, AstraZeneca, BMS, and Novartis Pharmaceuticals; has received consulting income from Abbott Diagnostics, Beckman-Coulter, Jana Care, Janssen, Novartis, Prevencio, Quidel, and Roche Diagnostics; and has served on clinical endpoint committees/data safety monitoring boards for Abbott, AbbVie, Amgen, CVRx, Medtronic, Pfizer, and Roche Diagnostics.
