Background
Elderly heart failure (HF) patients are underrepresented in clinical trials, though are a large proportion of patients in real-world practice. We investigated practice-based, secondary ...care HF management in a large group of chronic HF patients aged ≥ 80 years (octogenarians).
Methods
We analyzed electronic health records of 3490 octogenarians with chronic HF at 34 Dutch outpatient clinics in the period between 2013 and 2016 , 49% women. Study patients were divided into HFpEF LVEF ≥ 50%;
n
= 911 (26.1%), HFrEF LVEF < 40%;
n
= 2009 (57.6%) and HF with mid-range EF HFmrEF: LVEF 40–49%;
n
= 570 (16.3%).
Results
Most HFrEF patients aged ≥ 80 years received a beta blocker and a renin–angiotensin system (RAS) inhibitor (angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker), i.e. 78.3% and 72.8% respectively, and a mineralocorticoid receptor antagonist (MRA) was prescribed in 52.0% of patients. All three of these guideline-recommended medications (triple therapy) were given in only 29.9% of octogenarians with HFrEF, and at least 50% of target doses of triple therapy, beta blockers, RAS inhibitor and MRA, were prescribed in 43.8%, 62.2% and 53.5% of the total group of HFrEF patients. Contraindications or intolerance for beta blockers was present in 3.5% of the patients, for RAS inhibitors and MRAs in, 7.2% and 6.1%
Conclusions
The majority of octogenarians with HFrEF received one or more guideline-recommended HF medications. However, triple therapy or target doses of the medications were prescribed in a minority. Comorbidities and reported contraindications and tolerances did not fully explain underuse of recommended HF therapies.

ObjectivesTo validate the Global Registry of Acute Coronary Events (GRACE) risk score and examine the extent and impact of the risk–treatment paradox in contemporary patients with acute coronary ...syndrome (ACS).MethodsData from 5015 patients with ACS enrolled in the FORCE-ACS registry between January 2015 and December 2019 were used for model validation. The performance of the GRACE risk score for predicting in-hospital and 1-year mortality was evaluated based on indices of model discrimination and calibration. Differences in the delivery of guideline-recommended care among patients who survived hospitalisation (n=4911) per GRACE risk stratum were assessed and the association with postdischarge mortality was examined.ResultsDiscriminative power of the GRACE risk score was good for predicting in-hospital (c-statistic: 0.86; 95% CI: 0.83 to 0.90) and 1-year mortality (c-statistic: 0.82; 95% CI: 0.79 to 0.84). However, the GRACE risk score overestimated the absolute in-hospital and 1-year mortality risk (Hosmer-Lemeshow goodness-of-fit test p<0.01). Intermediate-risk and high-risk patients were 12% and 29% less likely to receive optimal guideline-recommended care compared with low-risk patients, respectively. Optimal guideline-recommended care was associated with lower mortality in intermediate- and high-risk patients.ConclusionsThe GRACE risk score identified patients at higher risk for in-hospital and 1-year mortality, but overestimated absolute risk levels in contemporary patients. Optimal guideline-recommended care was associated with lower mortality in intermediate-risk and high-risk patients, but was less likely to be delivered with increasing mortality risk.
Aims
Hyperkalaemia is observed frequently in heart failure (HF) patients and is associated with an impaired prognosis and underuse of mineralocorticoid receptor antagonists (MRAs). However, the ...effects of serum potassium on prescription of the full guideline recommended daily dose of 50 mg in real‐world daily practice are unknown. Therefore, we investigated serum potassium and its association with the prescribed MRA dose in a large cohort of chronic HF patients.
Methods and results
A total of 5346 patients with chronic HF with a left ventricular ejection fraction ≤40% from 34 Dutch outpatient HF clinics between 2013 and 2016 were analysed on serum potassium and MRA (spironolactone and eplenerone) dose. Data were stratified by potassium as a serum potassium level <4.0, 4.0 to 5.0 or >5.0 mmol/L. Multivariable logistic regression models were used to assess the association between serum potassium and MRA dose and to adjust for potential confounders. Mean serum potassium was 4.4 ± 0.5 mmol/L and hyperkalaemia (serum potassium >5.0 mmol/L) was present in 399 patients (7.5%). MRA was used in 3091 patients (58.1%). Patients with hyperkalaemia significantly less often received ≥100% of the target dose (50 mg) compared with patients with a serum potassium between 4.0–5.0 mmol/L and <4.0 mmol/L (7.7% vs. 9.5% vs. 13.6% respectively, P = 0.0078). In the multivariable regression analyses, patients with hyperkalaemia were significantly less likely to receive ≥100% of the target dose compared with patients with serum potassium 4.0–5.0 mmol/L (OR 0.38, 95% CI 0.15–0.97, P = 0.044). Additionally, a one unit increase in serum potassium was significantly associated with a lower odds of receiving ≥100% of the target dose (OR 0.69, 95% CI 0.49–0.98, P = 0.036).
Conclusions
In this large registry of real‐world chronic HF patients, both an increase in serum potassium and hyperkalaemia were associated with a lower odds of receiving the guideline‐recommended MRA dose.
ObjectivePatients with acute coronary syndrome (ACS) remain at high risk for recurrent ischaemic and bleeding events during follow-up. Our study aimed to quantify and compare the impact of these ...adverse events on quality of life (QoL).MethodsData from patients with ACS prospectively enrolled in the FORCE-ACS registry between January 2015 and December 2019 were used for this study. The primary ischaemic and bleeding events of interest were hospital readmission for ACS and Bleeding Academic Research Consortium type 2 or 3 bleeding during 12 months follow-up. QoL was measured using the EQ-5D Visual Analogue Scale (VAS) score and the 12-item Short Form Survey version 2 derived Physical Component Summary (PCS) and Mental Health Component Summary (MCS) scores at 12 months follow-up.ResultsIn total, 3339 patients (mean age 66.8 years, 27.9% women) were included. During follow-up, ischaemic events occurred in 202 patients (6.0%) and bleeding events in 565 patients (16.9%). After adjustment for demographic and clinical characteristics, ischaemic events remained independently associated with lower QoL regardless of metric used. Bleeding was also independently associated with lower EQ-5D VAS and PCS scores, but not with a lower MCS score. The QoL decrement associated with ischaemic events was numerically larger than the decrement associated with bleeding.ConclusionsIschaemic and bleeding events remain prevalent and are independently associated with lower QoL at 12 months follow-up in patients previously admitted for ACS. The incidence and impact of these adverse events should be considered when balancing individual ischaemic and bleeding risks.
Abstract Aims Despite clear guideline recommendations for initiating four drug classes in all patients with heart failure (HF) with reduced ejection fraction (HFrEF) and the availability of rapid ...titration schemes, information on real‐world implementation lags behind. Closely following the 2021 ESC HF guidelines and 2023 focused update, the TITRATE‐HF study started to prospectively investigate the use, sequencing, and titration of guideline‐directed medical therapy (GDMT) in HF patients, including the identification of implementation barriers. Methods and results TITRATE‐HF is an ongoing long‐term HF registry conducted in the Netherlands. Overall, 4288 patients from 48 hospitals were included. Among these patients, 1732 presented with de novo, 2240 with chronic, and 316 with worsening HF. The median age was 71 years (interquartile range IQR 63–78), 29% were female, and median ejection fraction was 35% (IQR 25–40). In total, 44% of chronic and worsening HFrEF patients were prescribed quadruple therapy. However, only 1% of HFrEF patients achieved target dose for all drug classes. In addition, quadruple therapy was more often prescribed to patients treated in a dedicated HF outpatient clinic as compared to a general cardiology outpatient clinic. In each GDMT drug class, 19% to 36% of non‐use in HFrEF patients was related to side‐effects, intolerances, or contraindications. In the de novo HF cohort, 49% of patients already used one or more GDMT drug classes for other indications than HF. Conclusion This first analysis of the TITRATE‐HF study reports relatively high use of GDMT in a contemporary HF cohort, while still showing room for improvement regarding quadruple therapy. Importantly, the use and dose of GDMT were suboptimal, with the reasons often remaining unclear. This underscores the urgency for further optimization of GDMT and implementation strategies within HF management.
Diagnostic and treatment strategies for acute coronary syndrome have improved dramatically over the past few decades, but mortality and recurrent myocardial infarction rates remain high. An aging ...population with increasing co-morbidities heralds new clinical challenges. Therefore, in order to evaluate and improve current treatment strategies, detailed information on clinical presentation, treatment and follow-up in real-world patients is needed. The Future Optimal Research and Care Evaluation in patients with Acute Coronary Syndrome (FORCE-ACS) registry (ClinicalTrials.gov Identifier: NCT03823547) is a multi-center, prospective real-world registry of patients admitted with (suspected) acute coronary syndrome. Both non-interventional and interventional cardiac centers in different regions of the Netherlands are currently participating. Patients are treated according to local protocols, enabling the evaluation of different diagnostic and treatment strategies used in daily practice. Data collection is performed using electronic medical records and quality-of-life questionnaires, which are sent 1, 12, 24 and 36 months after initial admission. Major end points are all-cause mortality, myocardial infarction, stent thrombosis, stroke, revascularization and all bleeding requiring medical attention. Invasive therapy, antithrombotic therapy including patient-tailored strategies, such as the use of risk scores, pharmacogenetic guided antiplatelet therapy and patient reported outcome measures are monitored. The FORCE-ACS registry provides insight into numerous aspects of the (quality of) care for acute coronary syndrome patients.
Aims Left atrial (LA) stretch-associated electrophysiological changes in patients with mitral stenosis (MS) predispose to atrial fibrillation. We hypothesized that the normalization of the pressure ...gradient by percutaneous transvenous mitral balloon valvotomy (PTMV) affects LA but not right atrial (RA) conduction, depending on the site of stimulation. Because direction-dependent (asymmetric) changes of conduction may contribute to arrhythmogenesis, we assessed conduction symmetry in MS patients and tested whether it is restored by PTMV. Methods and results In nine patients with MS, atrial effective refractory period and local activation times (ATs) were determined during stimulation before and after PTMV, with up to four decapolar catheters (LA and RA). Eight patients with ventricular pre-excitation served as controls. ATs at basic cycle length were similar before and after PTMV. With stimulation from either atrium, they were about 45 ms in the ipsilateral atrium and about 115 ms in the contralateral atrium. With premature stimulation, ATs increased dramatically. The shortest ATs were found in the RA with RA stimulation (78 ± 9 and 80 ± 6 ns, before and after PTMV). PTMV caused a shortening in LA-ATs (following LA stimulation) from 118 ± 14 to 82 ± 5 ms (before and after; P < 0.05). Asymmetry in conduction properties was therefore normalized by PTMV. PTMV led to a decrease in RA-ATs (following LA stimulation) from 196 ± 11 to 174 ± 13 ms (P < 0.02). In addition, following RA stimulation, the dispersion in ATs in the LA decreased significantly by PTMV (from 66 ± 10 to 34 ± 7 ms; P < 0.02). Conclusion MS is associated with LA conduction delay, increased LA dispersion of conduction, and conduction asymmetry. These changes are immediately reversible by PTMV.
The objective of this study was to validate the additional value of 3-dimensional (3D) transesophageal echocardiography (TEE) for patients with mitral valve stenosis undergoing percutaneous mitral ...balloon valvotomy (PTMV). Therefore, in a series of 21 patients with severe mitral valve stenosis selected for PTMV, 3D TEE was performed before and after PTMV. The mitral valve area was assessed by planimetry pre- and post-PTMV; the mitral valve volume was assessed and attention was paid to the amount of fusion of the commissures. These results were compared with findings by 2-dimensional transthoracic echocardiography using pressure half-time method for assessment of mitral valve area, and were analyzed for the prediction of successful outcome. Pre-PTMV the mitral valve area assessed by 3D TEE was 1.0 +/- 0.3 cm(2) vs 1.2 +/- 0.4 cm(2) assessed by 2-dimensional transthoracic echocardiography (P =.03) and post-PTMV it was 1.8 +/- 0.5 cm(2) vs 1.9 +/- 0.6 cm(2) (not significant), respectively. The mitral valve volume could be assessed by 3D TEE (mean 2.4 +/- 2.5 cm(3)) and was inversely correlated to a successful PTMV procedure (P <.001). The 3D TEE method enabled a better description of the mitral valvular anatomy, especially post-PTMV. We conclude that 3D TEE will have additional value over 2-dimensional echocardiography in this group of patients, for selection of patients pre-PTMV, and for analyzing pathology of the mitral valve afterward.
