A limited number of studies with smartwatches (SWs) investigated their potential in the field of heart failure (HF). The aim of this scoping review is to understand the extent of current literature on SWs in the HF population and the device's potential to improve disease management. The literature search was performed on PubMed and Embase in March 2024. Inclusion criteria included the use of commercialized SWs, HF diagnosis and peer-reviewed publications. Articles were excluded if the SW was not the study intervention or was part of a broader intervention programme. Reviews, case reports and study protocols were excluded. Of 1200 identified articles, 13 were included in the scoping review, encompassing 1171 patients with HF, and findings were presented in a descriptive summary table. Validity of several SW-collected physiological metrics was assessed against established technologies. Heart rate and step count measures were deemed moderately accurate in the HF population with Fitbit trackers (n = 5 patients, r = 0.54) and Garmin watches [n = 15 patients (mean age: 65.5 ± 12.6 years), concordance correlation coefficient (CCC) = 0.89 for Vivofit 1 and CCC = 0.92 for Vivofit 3], respectively, while calorimetry was the least reliable measurement [n = 19 patients (mean age: 65.1 ± 6.6 years), mean difference to indirect calorimeter: P = 0.01 for Fitbit Charge 2, P = 0.02 for Mio Slice]. Wrist-worn activity trackers were positively received by patients with HF [91.3% of adherence in research setting (n = 70 patients, median age (IQR): 79 years (76-82)), and 64% in real-world environment (n = 14 patients)] and their health-care providers (six cardiologists out of six acknowledged the data's usefulness), although device ownership ranged from 10 to 50% among the HF population. Physical activity information collected from SWs was found to be valuable in assisting cardiologists with their New York Heart Association (NYHA) functional class assessment, which is known for its limited objectivity and reproducibility. Multiple studies found that SWs, especially Fitbit devices, successfully identified a pattern where the degree of exercise intolerance increased with higher NYHA classes. These findings suggested that activity trackers can objectively evaluate the severity of physical activity limitations. As the functional classification of patients influences treatment strategies, SWs could serve as a valuable tool to facilitate and optimize outpatient disease management. SWs could be used as a complement to standard monitoring in HF. With continuous technological advances, it will be valuable to follow the deployment of SWs and to investigate their contribution to increased patient safety and consequently to health care cost reductions.

Aims: A novel marker left atrioventricular coupling index (LACI) has been proved to be associated with cardiovascular events in patients without history of cardiovascular disease. However, the studies on cardiac magnetic resonance-derived LACI in hypertrophic cardiomyopathy (HCM) patients are limited, and the prognostic value of LACI has still not been studied thoroughly, so we aimed to explore the association between LACI and adverse clinical outcomes in HCM patients.

Methods: A total of 206 HCM patients underwent cardiac magnetic resonance examination were retrospectively enrolled. LACI is defined by the ratio between the left atrial (LA) volume and the left ventricular (LV) volume in LV end-diastolic phase. The composite endpoint was categorized into death-related, heart failure-related, and arrhythmia-related events, reflecting mortality risk, heart failure progression, and arrhythmia burden, respectively. Receiver operating characteristics curve analysis was used to determine the optimal cut-off value for LACI to distinguish HCM patients at high risk of adverse clinical outcome. Multivariable Cox regression models were built including significant clinical variables, LA ejection fraction (LAEF), LA volume index (LAVI), late gadolinium enhancement (LGE) extent and LACI. The improvement of discrimination by adding LACI to a clinical model was assessed using C-statistic, net reclassification improvement (NRI) and integrated discrimination improvement (IDI).

Results: Thirty-four HCM patients reached the endpoint during a median follow-up time of 60 [interquartile range (50-68)] months. In the multivariate Cox regression analysis, LACI [hazard ratio 1.054, 95% confidence interval (CI): 1.037, 1.071; P < 0.001] was an independent predictor of the composite events after adjustment for age and atrial fibrillation. Then 40.09% was identified as an optimal cut-off for LACI in the risk stratification. Integrating LACI to the clinical model yielded higher C-statistic 0.892 with 95% CI (0.861, 0.922) compared with LA diameter, LAEF, LAVI and LGE extent, providing an improvement in prediction of high-risk patients (NRI = 0.627, 95% CI: 0.112-0.934; IDI = 0.295, 95% CI: 0.016-0.709).

Conclusions: LACI is an independent risk factor for clinical adverse outcome and is superior to conventional LA parameters and LGE extent for the identification of high-risk HCM patients.

Aims: Heart failure with preserved ejection fraction (HFpEF) continues to be an increasingly common health problem associated with a high mortality rate. Elevated levels of Growth differentiation factor-15 (GDF15) and N-terminal pro-brain natriuretic peptide (NT-proBNP) are reportedly associated with poor clinical outcomes in a broad range of cardiovascular diseases. The aim of the present study was to examine the effect of the combined assessment of these markers on clinical outcomes in patients with HFpEF.

Methods: This study is the prospective observational study. We measured the serum levels of GDF15 and NT-proBNP in 643 patients (mean age 73 ± 12, 42% females). All patients were prospectively followed up for a median period of 1998 days. Total 132 HF-related events and 88 all-cause deaths occurred during the follow-up period.

Results: Multivariate Cox proportional hazards regression analysis demonstrated that both serum GDF15 and NT-proBNP levels were independently associated with HF-related events after adjustment for confounding risk factors (GDF15: hazard ratio, 1.72; 95% confidence interval, 1.35-2.19; P < 0.0001 and NT-proBNP: hazard ratio, 1.63; 95% confidence interval, 1.25-2.13; P = 0.0003). Serum GDF15 levels improved the prediction capacity for HF-related events (0.7405 vs. 0.7190; P = 0.0422), with a significant net reclassification index (0.2724) and integrated discrimination improvement (0.0246). The C indices of GDF15 for HF-related events and all-cause deaths were significantly larger than those of NT-proBNP in men (HF-related events: 0.7389 vs. 0.6721; P = 0.0393, and all-cause deaths: 0.6922 vs.0.6109; P = 0.0262) but not in women. The combination of GDF15 and NT-proBNP levels stratified patients with HFpEF, identifying those at a high risk for HF-related events and all-cause deaths.

Conclusions: Serum GDF15 could be an additional prognostic information to NT-proBNP in patients with HFpEF. The prognostic abilities of serum GDF15 and NT-proBNP differed according to sex. These markers were the feasible markers for patients with HFpEF, identifying those at a high risk for HF-related events and all-cause deaths.

Aims: Cardiogenic shock (CS) is the deadliest manifestation of acute heart failure, with persistently high mortality rates and a lack of recent therapeutic breakthroughs. Accurate risk prediction is crucial in clinical decision-making and the design of future clinical trials. We aimed to validate the CLIP score, a biomarker-based risk score comprising cystatin C, lactate, interleukin-6 and NT-proBNP, for predicting mortality in acute coronary syndrome (ACS) related CS, and to compare its predictive value with the previously published CardShock risk score.

Methods and results: The study is a post hoc analysis of the CardShock Study, a prospective, observational European multicentre study on CS. The CLIP score was calculated 12 h after hospital admission, and its ability to predict 90-day mortality was assessed using are under the curve (AUC) of the receiver-operating characteristics (ROC) curve analysis. The discriminative ability of the CLIP score was compared with the CardShock risk score by comparing the AUC's. The cohort was dichotomized into low and high risk groups by the optimal cut-off value derived from the ROC analysis of the CLIP score. Kaplan-Meier curves were constructed to evaluate risk stratification when combining the CLIP and CardShock risk scores. The cohort (n = 121) comprised 77% (n = 93) men and the median age was 67 years (IQR 61-76). A total of 21% (n = 25) of the patients had non-ACS related CS. The CLIP score demonstrated appropriate predictive accuracy for 90-day mortality (AUC 0.84, 95% CI 0.77-0.91), comparable with the CardShock risk score (AUC 0.77 [95% CI 0.69-0.85]; P = 0.064 for comparison). A CLIP score cut-off of 0.28 stratified patients into high risk (65% mortality) and low risk (16% mortality) groups. In addition, incorporating the CLIP score enhanced risk stratification in all CardShock risk score categories.

Conclusions: The CLIP score, calculated within 12 h of hospital admission, accurately predicted 90-day mortality in CS and complemented the CardShock risk score. The biomarker-based score has potential utility in dynamic mortality risk assessment and could inform clinical management and trial design.

Aims: Dapagliflozin (DAPA), a sodium-glucose co-transporter 2 inhibitor, has been shown to reduce cardiovascular mortality among patients with chronic heart failure. We aimed to evaluate the impact on a worsening renal function (WRF) by adding DAPA as compared to standard decongestive therapy with loop diuretics alone.

Methods and results: We enrolled 114 consecutive acute decompensated heart failure (ADHF) patients with a left ventricular ejection fraction (LVEF) of less than 50%. The patients were prospectively randomized to be assigned either to DAPA group who received DAPA at a dose of 10 mg once daily within 24 h after admission or conventional therapy group (CON group) who received loop diuretics alone. All patients were adjusted by increasing or decreasing the loop diuretic by 10 mg to maintain a 1-2 mL/kg/h urine output. The primary endpoint was the incidence of WRF, which was defined as an increase in the serum creatinine of ≥0.3 mg/dL from baseline. The median age of the patients was 77 [interquartile range (IQR): 64, 85] years, 35% were female and the median LVEF was 33 [IQR: 28, 38] %. There was no significant difference in the incidence of WRF between the two groups (16.1%, n = 9 vs. 12.1%, n = 7, P value = 0.54). The total dose of loop diuretics through day 7 was lower in the DAPA group than CON group (184 ± 79.5 mg vs. 214 ± 66.5 mg, P value = 0.03).

Conclusions: This randomized prospective trial revealed the addition of DAPA within 24 h after admission reduced the diuretic dose without WRF.

Aims: Large-scale, real-world data on early initiation of sacubitril/valsartan in patients newly diagnosed (de novo) with HF with reduced ejection fraction (HFrEF) are limited. We examined the effectiveness of sacubitril/valsartan versus angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB) on all-cause and cause-specific hospitalizations among patients with de novo HFrEF from the Optum® dataset in the United States.

Methods: This retrospective cohort study included adult patients with de novo HFrEF (diagnosed ≤30 days) with left ventricular ejection fraction (LVEF) ≤40% who were first prescribed with sacubitril/valsartan or ACEi/ARB from 1 January 2016 to 31 March 2020. The primary endpoint (all-cause hospitalization) and secondary endpoints were analysed in propensity score-matched cohorts.

Results: A cohort of 3290 patients with de novo HFrEF who were prescribed with sacubitril/valsartan and a propensity-matched cohort of 6580 patients who were prescribed with ACEi/ARB were analysed. Overall, the mean (SD) age of patients was 63 (14) years, 34% were women, and baseline characteristics were balanced across treatment groups. Hypertension (67%), diabetes (33%) and chronic kidney disease (28%) were highly prevalent comorbidities. Patients in the sacubitril/valsartan cohort when compared with the ACEi/ARB cohort had lower annual rates of all-cause hospitalizations [incidence rate ratio (IRR): 0.81, 95% confidence interval (CI): 0.75-0.89, P < 0.001], cardiovascular (CV) hospitalizations (IRR: 0.80, 95% CI: 0.73-0.87, P < 0.001) and HF hospitalizations (IRR: 0.86, 95% CI: 0.78-0.95, P = 0.002).

Conclusions: Among patients with de novo HFrEF, sacubitril/valsartan (compared with that of ACEi/ARB) was associated with fewer all-cause, CV and HF hospitalizations. These findings are consistent with clinical trial evidence suggesting potential benefits of early initiation of sacubitril/valsartan in patients with HFrEF, including those soon after diagnosis.

Aims: The study aims to examine characteristics and outcomes associated with health-related quality of life (HRQoL) in patients with heart failure (HF) with preserved, mildly reduced and reduced ejection fraction (EF) (HFpEF, HFmrEF and HFrEF).

Methods and results: Data on HRQoL were collected in the Swedish Heart Failure Registry (SwedeHF; 2000-2021) using the EuroQoL 5-dimensional visual analogue scale (EQ 5D-vas). Baseline EQ 5D-vas scores were categorized as 'best' (76-100), 'good' (51-75), 'bad' (26-50) and 'worst' (0-25). Independent associations between patients' characteristics and EQ 5D-vas, as well as between EQ 5D-vas and outcomes were assessed. Of 40 809 patients (median age 74 years; 32% female), 29% were in the 'best', 41% in the 'good', 25% in the 'bad' and 5% in the 'worst' EQ 5D-vas categories, similarly distributed across all EF categories. Higher New York Heart Association (NYHA) class was strongly associated with lower EQ 5D-vas regardless of EF categories, followed by chronic obstructive pulmonary disease, smoking, body mass index, higher heart rate, anaemia, previous stroke, ischaemic heart disease, use of diuretics and living alone, whereas higher income, male sex, outpatient status and higher systolic blood pressure were inversely associated with lower EQ 5D-vas categories. Patients in the 'worst' EQ 5D-vas category as compared with the 'best' had the highest risk of all-cause death [adjusted hazard ratios 1.97, 95% confidence interval (CI) 1.64-2.37 in HFrEF, 1.77, 95% CI 1.30-2.40 in HFmrEF and 1.43 95% CI 1.02-2.00 in HFpEF].

Conclusions: Most patients were in the two highest EQ 5D-vas categories. Higher NYHA class had the strongest association with lower EQ 5D-vas categories, across all EF categories. Patients in the worst EQ 5D-vas category were at the highest risk of mortality.

Aims: We aim to elucidate the association of baseline eGFR and incident heart failure on patients receiving intensive BP treatment.

Methods and results: A post hoc analysis was conducted on the SPRINT database. Multivariab le Cox regression and interaction restricted cubic spline (RCS) analysis were performed to investigate the interaction between baseline eGFR and intensive BP control on heart failure prevention. The primary endpoint focused on incident heart failure. The study cohort comprised 8369 adults with a mean [SD] age of 68 [59-77] years, including 2940 women (35.1%). Over a median [IQR] follow-up period of 3.9 [2.0-5.0] years, 183 heart failure events were recorded. A significant interaction was observed between baseline eGFR and treatment groups in terms of heart failure prevention (Interaction P = 0.012). The risk of heart failure showed a sharp slope until eGFR = 75 mL/min/1.73 m² and then became flat by an interaction RCS. Intensive BP treatment did not exhibit a preventive effect on heart failure (HR (95% CI) = 1.03 (0.82-1.52)) when baseline eGFR was 75 mL/min/1.73 m² or lower. Conversely, when baseline eGFR was higher than 75 mL/min/1.73 m², a reduced risk of heart failure was observed (HR (95% CI) = 0.65 (0.41-0.98)). Intensive BP control did not increase the incident long-term dialysis regardless of baseline eGFR but was associated with a higher risk of eGFR reduction.

Conclusions: Among nondiabetic hypertensive patients, baseline eGFR serves as a crucial indicator for assessing the risk reduction potential of intensive BP control in heart failure prevention, with 75 mL/min/1.73 m² appearing as a suitable cut-off value.

Aims: Transcatheter edge-to-edge repair of the mitral valve (M-TEER) is known for its low complication rates. However, the optimal level and duration of post-procedural care remain unclear. This study aimed to identify the specific timeframe of post-procedural complications following M-TEER.

Methods and results: We conducted a retrospective analysis of 865 patients who underwent M-TEER at the University Hospital Düsseldorf between August 2010 and August 2023. Our analysis focused on a comprehensive examination of all acute post-procedural complications (1-100 h), considering the time point of occurrence or diagnosis. The complication analysed included cardiogenic shock, pericardial tamponade, stroke, cardiac arrhythmias, bleeding, acute kidney injury, myocardial infarction, peripheral vascular ischaemia and in-hospital mortality.

Results: The median age was 80 (74, 84) years, and the EuroScore II was high (6.5 [4.0, 12.0] %). Functional mitral regurgitation (MR) was more common than degenerative or mixed MR (69% vs. 20%. respectively; 11%). Technical success rate was 97.2%. Overall, acute post-procedural complications occurred in 87 patients (10.1%). Most complications (75.9%) occurred within the first 4 h post-procedure. 12.6% of the complications occurred during the period between 4 and 24 h post-procedure, and 11.5% of the complications happened between 24 and 100 h post-procedure. Life-threatening complications were observed only within the first 4 h post-procedure.

Conclusions: The majority of post-procedural complications after M-TEER occur within the first 4 h, with pericardial tamponade and major bleeding occurring only during this period. These findings provide valuable insight for physicians in determining the optimal surveillance and monitoring duration after M-TEER within clinical settings.
