Quality of life in patients with heart failure and improved ejection fraction: one-year changes and prognosis.

AIMS: The criteria for patients with heart failure (HF) and improved ejection fraction (HFimpEF) are a baseline left ventricular ejection fraction (LVEF) ≤40%, a ≥10-point increase from baseline LVEF, and a second LVEF measurement >40%. We aimed to (i) assess patients with HF and reduced LVEF (HFrEF) at baseline and compare quality of life (QoL) changes between those that fulfilled and those that did not fulfil the HFimpEF criteria 1 year later and (ii) assess the prognostic role of QoL in patients with HFimpEF. METHODS: We reviewed data from a prospective registry of real-world outpatients with HF that were assessed for LVEF and QoL at a first visit to the HF clinic and 1 year later. QoL was evaluated with the Minnesota Living with Heart Failure Questionnaire (MLWHFQ). The primary prognostic endpoint was the composite of all-cause death or HF hospitalization. RESULTS: Baseline and 1-year LVEF and MLWFQ scores were available for 1040 patients with an initial LVEF ≤40% (mean age, 65.2 ± 11.7 years; 75.9% men). The main aetiology was ischaemic heart disease (52.9%), and patients were mostly in New York heart Association Classes II (71.1%) and III (21.6%). At baseline, the mean LVEF was 28.5% ± 7.3, and the mean MLWHFQ score was 30.2 ± 19.5. After 1 year, the mean LVEF increased to 38.0% ± 12.2, and the MLWHFQ scores improved to 17.4 ± 16.0. In 361 patients that fulfilled the HFimpEF criteria (34.7%), significant improvements were observed in both LVEF (from 28.7% ± 6.6 to 50.9% ± 7.6, P < 0.001) and QoL (from 32.9 ± 20.6 to 16.9 ± 16.0, P < 0.001). Patients that did not fulfil the HFimpEF criteria also showed significant improvements in LVEF (from 28.4% ± 7.6 to 31.1% ± 7.9, P < 0.001) and QoL (from 28.7 ± 18.8 to 17.6 ± 15.9, P < 0.001). However, the QoL improvement was significantly higher in the HFimpEF group (-16.0 ± 23.8 vs. -11.1 ± 20.3, P = 0.001), despite the worse mean baseline MLWHFQ score, compared with the non-HFimpEF group (P = 0.001). The 1-year QoL was similar between groups (P = 0.50). The 1-year MLWHFQ score was independently associated with outcomes; the hazard ratio for the composite endpoint was 1.02 (95% CI: 1.01-1.03, P = 0.006). In contrast, the QoL improvement (with a cut-off ≥5 points) was not independently associated with the composite outcome. CONCLUSIONS: Patients with HFrEF showed improved QoL after 1 year, regardless of whether they met the HFimpEF criteria. The similar 1-year QoL perception between groups suggested that factors other than LVEF influenced QoL perception. The 1-year QoL was superior to the QoL change from baseline for predicting prognosis in patients with HFimpEF.

Prognostic value of lung ultrasound in chronic stable ambulatory heart failure patients.

INTRODUCTION AND OBJECTIVES: The role of lung ultrasound (LUS) in acute heart failure (HF) has been widely studied, but little is known about its usefulness in chronic HF. This study assessed the prognostic value of LUS in a cohort of chronic HF stable ambulatory patients. METHODS: We included consecutive outpatients who attended a scheduled follow-up visit in a HF clinic. LUS was performed in situ. The operators were blinded to clinical data and examined 8 thoracic areas. The sum of B-lines across all lung zones and the quartiles of this addition were used for the analyses. Linear regression and Cox regression analyses were performed. The main clinical outcomes were a composite of all-cause death or hospitalization for HF and mortality from any cause. RESULTS: A total of 577 individuals were included (72% men; 69± 12 years). The mean number of B-lines was 5±6. During a mean follow-up of 31±7 months, 157 patients experienced the main clinical outcome and 111 died. Having ≥ 8 B-lines (Q4) doubled the risk of experiencing the composite primary event (P <.001) and increased the risk of death from any cause by 2.6-fold (P <.001). On multivariate analysis, the total sum of B-lines remained independent predictive factor of the composite endpoint (HR, 1.04; 95%CI, 1.02-1.06; P=.002) and of all-cause death (HR, 1.04; 95%CI, 1.02-1.07; P=.001), independently of whether or not N-terminal pro-B-type natriuretic peptide (NT-proBNP) was included in the model (P=.01 and P=.008, respectively), with a 3% to 4% increased risk for each 1-line addition. CONCLUSIONS: LUS identified patients with stable chronic HF at high risk of death or HF hospitalization.

Consumption of fresh Iberian pork: Two-stage cluster for the identification of segments of consumers according to their habits and lifestyles.

This study investigates the behaviour of consumers regarding four cuts of Iberian meat with greater presence in the market: tenderloin, secreto, presa and pluma. A sample of 1501 consumers responded to an online survey about their consumption habits for these four cuts, sociodemographic characteristics and lifestyle. From this information, three homogeneous segments of consumers were identified: "unmotivated and indifferent to Iberian meat", "innovators and stakeholders" and "traditional with frequent consumption". The Iberian tenderloin and the secreto were the most consumed cuts in all consumption segments, while the main reason for the lower consumption of presa and pluma was "I don't like it", especially among "unmotivated" consumers.

Cardiovascular Effects of Pharmacological Targeting of Sphingosine Kinase 1.

High blood pressure is a risk factor for cardiovascular diseases. Ang II (angiotensin II), a key pro-hypertensive hormone, mediates target organ consequences such as endothelial dysfunction and cardiac hypertrophy. S1P (sphingosine-1-phosphate), produced by Sphk1 (sphingosine kinase 1), plays a pivotal role in the pathogenesis of hypertension and downstream organ damage, as it controls vascular tone and regulates cardiac remodeling. Accordingly, we aimed to examine if pharmacological inhibition of Sphk1 using selective inhibitor PF543 can represent a useful vasoprotective and cardioprotective anti-hypertensive strategy in vivo. PF543 was administered intraperitoneally throughout a 14-day Ang II-infusion in C57BL6/J male mice. Pharmacological inhibition of Sphk1 improved endothelial function of arteries of hypertensive mice that could be mediated via decrease in eNOS (endothelial nitric oxide synthase) phosphorylation at T495. This effect was independent of blood pressure. Importantly, PF543 also reduced cardiac hypertrophy (heart to body weight ratio, 5.6±0.2 versus 6.4±0.1 versus 5.9±0.2 mg/g; P<0.05 for Sham, Ang II+placebo, and Ang II+PF543-treated mice, respectively). Mass spectrometry revealed that PF543 elevated cardiac sphingosine, that is, Sphk1 substrate, content in vivo. Mechanistically, RNA-Seq indicated a decreased expression of cardiac genes involved in actin/integrin organization, S1pr1 signaling, and tissue remodeling. Indeed, downregulation of Rock1 (Rho-associated coiled-coil containing protein kinase 1), Stat3 (signal transducer and activator of transcription 3), PKC (protein kinase C), and ERK1/2 (extracellular signal-regulated kinases 1/2) level/phosphorylation by PF543 was observed. In summary, pharmacological inhibition of Sphk1 partially protects against Ang II-induced cardiac hypertrophy and endothelial dysfunction. Therefore, it may represent a promising target for harnessing residual cardiovascular risk in hypertension.

Educational level and self-care behaviour in patients with heart failure before and after nurse educational intervention.

BACKGROUND: Self-care is important for heart failure (HF) management and may be influenced by the patient's educational level. AIM: We assessed the relationship of educational level with baseline self-care behaviour and changes one year after a nursing intervention in HF outpatients attending a HF unit. PATIENTS AND METHOD: Three hundred and thirty-five HF patients were studied, with a median age of 67 years (P(25-75) 57-75) and a median HF duration of six months (P(25-75) 1-36). HF aetiology was mainly ischaemic heart disease (53.4%). Median ejection fraction was 30% (P(25-75) 24-37%). The functional class was mainly II (66.3%) and III (25.7%). Educational levels were: very low 17.3%; low 62.1%; medium-high 20.6%. Patients were evaluated at the first visit (baseline) and one year after the educational intervention with the nine-item European Heart Failure Self-care Behaviour Scale. RESULTS: Median patient scores differed in the baseline (19 (P(25-75) 15-26) vs. 16 (P(25-75) 13-21) vs. 15 (P(25-75) 12.5-15.5)) and the one-year evaluation (15 (P(25-75) 13-17) vs. 13 (P(25-75) 11-15) vs. 12 (P(25-75) 10-14)) for the three educational levels, respectively, with statistically significant differences between levels (p=0.007 to p<0.001) except between low and medium-high education at one year (p=0.057). In the one-year evaluation, self-care behaviour significantly improved in the three educational groups (p<0.001), with a similar, albeit not statistically significant, magnitude of improvement in all groups. CONCLUSIONS: Self-care behaviour at baseline and one year after a nursing intervention was better in patients with a higher education, although the improvement with the intervention was similar irrespective of the educational level.

Evaluation of a telemedicine system for heart failure patients: feasibility, acceptance rate, satisfaction and changes in patient behavior: results from the CARME (CAtalan Remote Management Evaluation) study.

BACKGROUND: Telemedicine can be useful for managing heart failure (HF), but patient acceptance of telemedicine and its impact on patient behavior are unclear. AIMS: To assess a telemedicine program in a HF Unit. METHODS AND RESULTS: This sub-analysis of the CARME study assessed the use of an interactive telemedicine platform. This prospective intervention study had a before/after design with HF patients randomized 1:1 into two groups: (A) Motiva system (educational videos, motivational messages, and questionnaires); and (B) Motiva system + telemonitoring of blood pressure, heart rate and weight. Of 211 patients screened, 44 were excluded, 62 did not consent to participate and 8 withdrew consent prior to installation of the system. The final study population included 97 patients. During 1 year of follow-up, 22 patients voluntarily discontinued use of the system, 5 died (three after early discontinuation) and 5 withdrew consent before the last evaluation. A total of 15,017 questionnaires were sent to patients, with a median response rate of 88%. Satisfaction with the system and tools was high (median score 8.4/10), especially with the self-monitoring chart, scale and sphygmomanometer. Positive changes were observed in patient behavior, especially for blood pressure and weight control (p < 0.001). After the study, 65% of the patients wished to continue with telemonitoring, particularly those in group B (p = 0.004). CONCLUSION: Less than half of our patients participated in the telemedicine study. However, those who completed the study had confidence in the system, a high degree of satisfaction with the tools and positive behavioral changes.

[Noninvasive remote telemonitoring for ambulatory patients with heart failure: effect on number of hospitalizations, days in hospital, and quality of life. CARME (CAtalan Remote Management Evaluation) study]. / Telemonitorización no invasiva en pacientes ambulatorios con insuficiencia cardiaca: efecto en el número de hospitalizaciones, días de ingreso y calidad de vida. Estudio CARME (CAtalan Remote Management Evaluation).

INTRODUCTION AND OBJECTIVES: Multidisciplinary strategies for the management of heart failure (HF) improve outcomes. We aimed to evaluate the effectiveness of noninvasive home telemonitoring in ambulatory patients with HF already included in a structured multidisciplinary HF program. METHODS: Prospective intervention study with before/after comparison design of an interactive telemedicine platform in HF patients, randomized 1:1 into two groups: A) Motiva System with educational videos, motivational messages, and questionnaires, and B) Motiva System + self monitoring of blood pressure, heart rate, and weight. Hospitalizations were compared over 12 months prior to and post study inclusion. Quality of life was evaluated using the generic EuroQoL visual analogue scale and the specific questionnaire Minnesota Living With Heart Failure Questionnaire. RESULTS: There were 92 patients included (71% male; 66.3 ± 11.5 years; 71% ischemic aetiology). During real-time telemonitoring over 11.8 months (interquartile range 8.6-12), 14,730 questionnaires were administered with 89% median response rate. Hospitalizations for HF decreased by 67.8% (P = .010) and for other cardiac causes by 57.6% (P = .028). The number of days in hospital for HF decreased by 73.3% (P =.036), without statistically significant differences between groups, and for other cardiac causes by 82.9% (P =.008). The perception of quality of life improved significantly both for the generic scale (P < .001) and for the HF specific questionnaire (P=.005). CONCLUSIONS: HF patients who used an interactive telehealth system with motivational support tools at home spent less time in hospital and felt their quality of life had significantly improved. No significant differences were observed between groups.

Mortality and cause of death in patients with heart failure: findings at a specialist multidisciplinary heart failure unit.

INTRODUCTION AND OBJECTIVES: Heart failure mortality is similar to or even higher than that due to various cancers. It is usually associated with disease progression, though sudden death has also been reported as a frequent cause of mortality. The objectives of this study were to investigate mortality and its causes in outpatients with heart failure of different etiologies who were treated in a specialist multidisciplinary unit, and to identify associated factors. METHODS: The follow-up cohort study (median duration 36 months) involved 960 patients (70.9% male; median age 69 years; ejection fraction 31%; and the majority had an ischemic etiology and were in functional class II or III). RESULTS: Overall, 351 deaths (36.5%) occurred: 230 due to cardiovascular causes (65.5%), mainly heart failure (33.2%) and sudden death (16%); 94 due to non-cardiovascular causes (26.8%), mainly malignancies (10.5%) and septic processes (6.8%); and 27 (7.7%) due to unknown causes. Mortality was independently associated with age, sex, functional class, ejection fraction, time since symptom onset, ischemic etiology, diabetes, creatinine clearance rate, peripheral vascular disease, fragility, and the absence of treatment with an angiotensin-converting enzyme inhibitor or angiotensin-II receptor blocker, beta-blockers, statins or antiplatelet agents. The principal factor associated with cardiovascular death was an ischemic etiology. No factor studied clearly predicted sudden death. CONCLUSIONS: Even though mortality in patients treated at a specialist heart failure unit was not low, a quarter died from non-cardiovascular causes. The principal factor associated with cardiovascular death was an ischemic etiology. Only 5.8% of the study population experienced sudden death.
