Aims Reducing sodium intake is necessary for patients with chronic heart failure (CHF). Salt substitutes (saltSubs) have become increasingly popular as recommendations by healthcare professionals (HCPs) as well as options for patients and their caregivers. However, their consumption is generally potassium based and remains poorly evaluated in CHF management. Their impact on guideline‐directed medical therapies (GDMTs) also remains unknown. The primary objective of this study was to provide a description and estimate of HCP recommendations and reported use of saltSubs in France. Secondary objectives were to identify if there was an association between these recommendations by HCPs and the use of GDMTs. Methods and results A nationwide, questionnaire‐based, cross‐sectional, epidemiological study was conducted from September 2020 to July 2021. Data collection included baseline characteristics, the use and recommendations of saltSubs, and the use of GDMTs, which included (i) angiotensin‐converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) or angiotensin receptor–neprilysin inhibitors (ARNis), (ii) mineralocorticoid receptor antagonists (MRAs), and/or (iii) beta‐blockers (BBs). In total, 13% of HCPs advised saltSubs and 17% of patients and 22% of caregivers reported their consumption. CHF patients advised to take saltSubs did not differ in terms of left ventricular ejection fraction (EF) <40%, ischaemic origin, and New York Heart Association III–IV class, but were more recently hospitalized for acute HF (P = 0.004). HCPs who recommended saltSubs to patients were more likely to advise an anti‐diabetic diet (P < 0.001), cholesterol‐lowering diet (P < 0.001), and exercise (P = 0.018). In the overall population, ACEi/ARB/ARNi use was less frequent in case of saltSub recommendations (74% vs. 82%, P = 0.012). The concomitant prescription of none, one, two, or three GDMTs was less favourable in case of saltSub recommendations (P = 0.046). There was no significant difference for the presence of MRA (56% vs. 58%) and/or BB (78% vs. 82%). The under‐prescription of ACEi/ARB/ARNi was found when patients had EF < 40% (P = 0.029) and/or EF ≥ 40% (P = 0.043). In the subgroup with left ventricular EF ≥ 40%, we found a higher thiazide use (P = 0.014) and a less frequent use of low EF GDMTs (P = 0.044) in case of being recommended saltSubs. Conclusions Beyond the well‐established risk for hyperkalaemia, our preliminary results suggest a potentially negative impact of saltSubs on GDMT use, especially for ACEis/ARBs/ARNis in CHF management. saltSub recommendations and their availability from open sale outlets should be considered to avoid possible misuse or deference from GDMTs in the future. Informed advice to consumers should also be considered from HCPs or pharmacists.

Aside from the culprit plaque, the presence of vulnerable plaques in patients with acute coronary syndrome (ACS) may be associated with future cardiac events. A link between calcification and plaque rupture has been previously described. To assess whether analysis of the calcium component of coronary plaques using CT angiography, coronary computed tomographic angiography (CCTA) can help to detect additional vulnerable plaques in patients with non-ST elevation myocardial infarction (NSTEMI). Cross sectional study of consecutive patients referred for NSTEMI from 30 July to 30 August 2018 with CCTA performed before coronary angiography with systematic optical coherence tomography (OCT) analysis of all coronary arteries within 24 h of clinical onset of NSTEMI. Three types of plaques were defined: culprit plaques defined by angiography (vulnerable culprit plaques-VCP) - plaques with a fibrous cap thickness < 65 microns or thrombus in OCT (vulnerable non-culprit plaque-VNCP) - plaques with a fibrous cap thickness ≥ 65 microns in OCT (stable plaque-SP). A total of 134 calcified plaques were identified in 29 patients (73% male, 59 ± 14 years) with 29(22%) VCP, 28(21%) VNCP and 77(57%) SP. Using CCTA analysis of the calcium component, factors associated with vulnerable plaques were longer calcification length, larger calcification volume, lower calcium mass, higher Agatston score plaque-specific (ASp), presence of spotty calcifications and an intimal position in the wall. In multivariate analysis, ASp, calcification length and spotty calcifications were independently associated to vulnerable plaques. There was no difference between VCP and VNCP. CCTA analysis of calcium component of the plaque could help to identify additional vulnerable plaques in NSTEMI patients.

The left ventricular (LV) developed pressure is a marker of contractility, associated with a poor prognosis during systolic heart failure. The maximal first derivative or slope of the radial pulse wave (Rad dP/dt) has been proposed as a marker of LV systolic function. This study sought to assess the prognostic value of the baseline dP/dt of the radial pulse in patients with heart failure. The Rad dP/dt was noninvasively measured by applanation tonometry, and its effect on mortality was analyzed by using multivariate Cox regression models. We studied 310 consecutive patients. Mean follow-up was 327 ± 187 days, and 64 patients died or were transplanted during this period. Death or transplantation was associated with New York Heart Association class III or IV, low systolic or mean blood pressure, low LV ejection fraction, and low Rad dP/dt (634.6 ± 373.3 vs 730.2 ± 367.4 mm Hg/s for patients who survived without transplantation, P < .02). A Rad dP/dt <440 mm Hg/s was associated with death or transplantation before and after adjustment for confounding variables (OR [95% CI] 2.19 [1.33-3.58] and 2.88 [1.29-6.38], respectively, P < .01 for both). This relationship was independent of pulse pressure and no significant interaction was found between the Rad dP/dt and the pulse pressure. This study demonstrates, for the first time, that the Rad dP/dt, proposed as a noninvasive peripheral marker of LV systolic function, is an independent predictor of death or transplantation in patients with HF regardless of LV ejection fraction.

Background Acute heart failure (AHF) is a common serious condition that contributes to about 5% of all emergency hospital admissions in Europe. Hypothesis To assess the type and chronology of the first AHF symptoms before hospitalization and to examine the French healthcare system pathways before, during and after hospitalization. Material and Methods A retrospective observational study including patients hospitalized for AHF Results 793 patients were included, 59.0% were men, 45.6% identified heart failure (HF) as the main cause of hospitalization; 36.0% were unaware of their HF. Mean age was 72.9 ± 14.5 years. The symptoms occurring the most before hospitalization were dyspnea (64.7%) and lower limb edema (27.7%). Prior to hospitalization, 47% had already experienced symptoms for 15 days; 32% of them for 2 months. Referral to hospital was made by the emergency medical assistance service (SAMU, 41.6%), a general practitioner (GP, 22.3%), a cardiologist (19.5%), or the patient (16.6%). The modality of referral depended more on symptom acuteness than on type of symptoms. A sudden onset of AHF symptoms led to making an emergency call or to spontaneously attending an emergency room (ER), whereas cardiologists were consulted when symptoms had already been present for over 15 days. Cardiologists referred more patients to cardiology departments and fewer patients to the ER than general practitioners or the SAMU. Conclusion This study described the French healthcare system pathways before, during and after hospitalization AHF. AHF clinic network should be developed to provide adequate care for all HF patients and create awareness regarding AHF symptoms.

(1) Background: There is much debate about the use of salt-restricted diet for managing heart failure (HF). Dietary guidelines are inconsistent and lack evidence. (2) Method: The OFICSel observatory collected data about adults hospitalised for HF. The data, collected using study-specific surveys, were used to describe HF management, including diets, from the cardiologists’ and patients’ perspectives. Cardiologists provided the patients’ clinical, biological, echocardiography, and treatment data, while the patients provided dietary, medical history, sociodemographic, morphometric, quality of life, and burden data (burden scale in restricted diets (BIRD) questionnaire). The differences between the diet recommended by the cardiologist, understood by the patient, and the estimated salt intake (by the patient) and diet burden were assessed. (3) Results: Between March and June 2017, 300 cardiologists enrolled 2822 patients. Most patients (90%) were recommended diets with <6 g of salt/day. Mean daily salt consumption was 4.7 g (standard deviation (SD): 2.4). Only 33% of patients complied with their recommended diet, 34% over-complied, and 19% under-complied (14% unknown). Dietary restrictions in HF patients were associated with increased burden (mean BIRD score of 8.1/48 [SD: 8.8]). (4) Conclusion: Healthcare professionals do not always follow dietary recommendations, and their patients do not always understand and comply with diets recommended. Restrictive diets in HF patients are associated with increased burden. An evidence-based approach to developing and recommending HF-specific diets is required.

Subendocardial viability ratio (SEVR), defined as diastolic to systolic pressure-time integral ratio, is a useful tool reflecting the balance between coronary perfusion and arterial load. Suboptimal SEVR creating a supply-demand imbalance may limit favorable cardiac response to cardiac rehabilitation (CR). To explore this hypothesis, we designed a study to analyze the relationship between baseline SEVR and response to CR in patients with coronary artery disease (CAD). In this prospectively study, after baseline arterial tonometry, echocardiography, and cardiopulmonary exercise tests (CPETs), patients undergone 20 sessions of CR. Post-CR echocardiographic and CPET measurements were obtained for comparison. Final study population was comprised of fifty subjects. Study population was divided into two subgroups by median SEVR value (1.45, interquartile range 0.38). Although both groups showed significant improvements in peak VO2, significant improvements in oxygen pulse (πO2) (from 16.1±3.4 to 19.1±4.8 mL O2.kg-1.beat-1; p<0.001) and stroke volume index (from 31±5 to 35±6 mL; p=0.008) were observed in only the patients in the above-median subgroup. The change in πO2 was also significantly higher in the above-median SEVR subgroup (2.9±3.3 vs. 0.5±2.4; p=0.007). Our study shows that baseline supply-demand imbalance may limit systolic improvement response to CR in patients with CAD.

Functional capacity is one of the cardinal determinants of morbidity and mortality in patients with coronary artery disease (CAD). We hypothesized that baseline cardiovascular mechanics, including cardiac systolic and diastolic functions, arterial mechanics, and ventriculoarterial interaction, may play a role in predicting exercise capacity in patients with CAD. Fifty consecutive patients with CAD who were referred to cardiac rehabilitation were prospectively included in the study. Patients with non-sinus rhythms or severe valvular disease were excluded. Full left ventricular pressure-volume loops were constructed and arterial mechanics was evaluated using echocardiographic and tonometric measurements. Cardiopulmonary exercise tests were performed to measure exercise capacity. Fifty patients were enrolled in the study. Ventriculo-arterial coupling showed a moderate correlation with peak oxygen consumption (VO2) (r=0.410, p=0.04) in patients with reduced left ventricular ejection fraction (LVEF). Only left ventricular volume at 15 mm Hg (r=0.514, p<0.01) in diastolic parameters (stiffness constant, p=0.75; ventricular compliance, p=0.17) and arterial compliance (r=0.467, p=0.01) in arterial parameters [arterial elastance, p=0.27; systemic vascular resistance, p=0.45; augmentation pressure, p=0.85; augmentation index (AIx), p=0.63; heart rate-corrected AIx, p=0.68] emerged as significant factors correlated with peak VO2 in patients with normal LVEF. Comprehensive evaluation of resting cardiovascular mechanics can give clues about exercise-recruited reserves of the cardiovascular system. Optimization of ventriculo-arterial coupling in patients with reduced LVEF and arterial compliance in patients with normal LVEF should be the main target in patients with CAD and limited functional capacity.

BackgroundCoronavirus disease 2019 (COVID-19) is a respiratory disease associated with endotheliitis and microthrombosis.ObjectivesTo correlate endothelial dysfunction to in-hospital mortality in a bi-centric cohort of COVID-19 adult patients.MethodsConsecutive ambulatory and hospitalized patients with laboratory-confirmed COVID-19 were enrolled. A panel of endothelial biomarkers and von Willebrand factor (VWF) multimers were measured in each patient ≤ 48 h following admission.ResultsStudy enrolled 208 COVID-19 patients of whom 23 were mild outpatients and 189 patients hospitalized after admission. Most of endothelial biomarkers tested were found increased in the 89 critical patients transferred to intensive care unit. However, only von Willebrand factor antigen (VWF:Ag) scaled according to clinical severity, with levels significantly higher in critical patients (median 507%, IQR 428–596) compared to non-critical patients (288%, 230–350, p < 0.0001) or COVID-19 outpatients (144%, 133–198, p = 0.007). Moreover, VWF high molecular weight multimers (HMWM) were significantly higher in critical patients (median ratio 1.18, IQR 0.86–1.09) compared to non-critical patients (0.96, 1.04–1.39, p < 0.001). Among all endothelial biomarkers measured, ROC curve analysis identified a VWF:Ag cut-off of 423% as the best predictor for in-hospital mortality. The accuracy of VWF:Ag was further confirmed in a Kaplan–Meier estimator analysis and a Cox proportional Hazard model adjusted on age, BMI, C-reactive protein and d-dimer levels.ConclusionVWF:Ag is a relevant predictive factor for in-hospital mortality in COVID-19 patients. More than a biomarker, we hypothesize that VWF, including excess of HMWM forms, drives microthrombosis in COVID-19.

It has been clearly demonstrated that the maternal nutritional status during pregnancy and lactation has long-term effects on offspring health. In mammals, milk represents the first maternal support provided to the newborns so that its composition may play a major role in long-term programming. We therefore assessed the effects of maternal high-fat/high-sugar obesogenic (OD) or control (CD) diets on offspring growth and adiposity in the rabbit. Between 7 and 20 wk of age, the BW gain of OD milk-fed rabbits was higher than that of CD milk-fed rabbits ( < 0.05). Body fat mass measurements at 21 wk of age revealed a significant increase in body adiposity as a function of milk ingested during the neonatal period, in both female and male offspring ( < 0.05). A marked weight gain difference was observed according to the milk in both female and male offspring. Moreover, we investigated the composition in major proteins and leptin levels in milk from OD or CD diet-fed dams. Liquid chromatography-mass spectrometry analysis of individual CD skimmed milk samples enabled identification and quantification of the rabbit main milk proteins and of their main phosphorylated isoforms at 2 different stages of lactation (3 and 10 d). Here we show that the OD diet induced a reduction in the whey acidic protein content concomitantly with both an increase in serum albumin and lactoferrin contents and in the phosphorylated isoforms of the main milk proteins. Furthermore, a sharp rise in leptin levels was observed in the milk of OD diet-fed dams on Day 10 of lactation when compared with CD diet animals ( < 0.05). Taken together, these findings provide evidence that lactation is a critical window of development during which exposure to a deleterious diet is highly detrimental to long-term outcomes. Moreover, these insights suggest that it may be possible to prevent at least some of the adverse effects of inadequate maternal nutrition on the long-term metabolic outcomes of the offspring through nutritional interventions applied during the lactation period.

BACKGROUNDHuman papillomavirus (HPV) testing as primary cervical cancer screening has not been studied in Caribbean women. We tested vaginal self-collection versus physician cervical sampling in a population of Haitian women. METHODSParticipants were screened for high-risk HPV with self-performed vaginal and clinician-collected cervical samples using Hybrid Capture 2 assays (Qiagen, Gaithersburg, MD). Women positive by either method then underwent colposcopy with biopsy of all visible lesions. Sensitivity and positive predictive value were calculated for each sample method compared with biopsy results, with κ statistics performed for agreement. McNemar tests were performed for differences in sensitivity at ≥cervical intraepithelial neoplasia (CIN)-I and ≥CIN-II. RESULTSOf 1845 women screened, 446 (24.3%) were HPV positive by either method, including 105 (5.7%) only by vaginal swab and 53 (2.9%) only by cervical swab. Vaginal and cervical samples were 91.4% concordant (κ = 0.73 [95% confidence interval, 0.69–0.77], P < 0.001). Overall, 133 HPV-positive women (29.9%) had CIN-I, whereas 32 (7.2%) had ≥CIN-II. The sensitivity of vaginal swabs was similar to cervical swabs for detecting ≥CIN-I (89.1% vs. 87.9%, respectively; P = 0.75) lesions and ≥CIN-II disease (87.5% vs. 96.9%, P = 0.18). Eighteen of 19 cases of CIN-III and invasive cancer were found by both methods. CONCLUSIONSHuman papillomavirus screening via self-collected vaginal swabs or physician-collected cervical swabs are feasible options in this Haitian population. The agreement between cervical and vaginal samples was high, suggesting that vaginal sample–only algorithms for screening could be effective for improving screening rates in this underscreened population.
