RESUMEN

BACKGROUND AND AIMS: This study investigates the prognostic impact of body mass index (BMI) on the risk of 30-day all-cause mortality in patients with cardiogenic shock (CS). Due to ongoing epidemiological developments, the characteristics of patients with cardiovascular disease are consistently changing. Especially increasing rates of obesity and associated comorbidities have been observed. However, data regarding the prognostic value of BMI in patients with CS remains inconclusive. METHODS AND RESULTS: Consecutive patients with CS were included from 2019 to 2021. The prognostic value of BMI (i.e., BMI 18.5-<25; 25-30 and >30 kg/m2) was analyzed using Kaplan-Meier and multivariable Cox proportional regression analyses regarding the primary endpoint of 30-day all-cause mortality. Additional risk stratification was performed based on the presence or absence of CS related to acute myocardial infarction (AMI). 256 patients with a median BMI of 26.4 kg/m2 were included. The overall risk of 30-day all-cause mortality was 53.5%. Within the entire study cohort, BMI was not associated with the risk of 30-day all-cause mortality (log rank p ≥ 0.107). In contrast, BMI >30 kg/m2 was associated with higher risk of 30-day all-cause mortality when compared to BMI <25 kg/m2 in patients with AMI-CS (78% vs 47%; log rank p = 0.017), which was confirmed after multivariable adjustment (HR = 2.466; 95% CI 1.126-5.399; p = 0.024). However, BMI was not associated with mortality in patients with non-AMI-CS. CONCLUSION: BMI >30 kg/m2 was associated with increased risk of 30-day all-cause mortality in patients with AMI-CS, but not in non-AMI-CS.

RESUMEN

BACKGROUND: Knowing what to eat and realizing the significance of healthful eating habits are among the important steps to promoting eating behavior. The current study aims to assess the nutrition knowledge (NK) among a convenient sample in four different countries, determine the association between different demographic factors and NK, and investigate the need for future interventions on nutrition in the four selected countries. METHODS: A cross-sectional multi-national survey study among a convenient sample of 8,191 subjects from Egypt, Syria, Saudi Arabia, and Jordan who undertook surveys between January 2019 and January 2020. A pre-tested interview questionnaire was utilized for data collection from study participants. It included three sections: i) Sociodemographic characteristics:. ii). Section two included twenty-one questions related to NK.. iii). Section three included one question about NK sources. RESULTS: About three-quarters showed inadequate nutrition knowledge (73.1%). Youth (15-24 yrs.) were more dependent on social media, with 87% using it as a primary source of NK, while adults (≥ 25 yrs.) demonstrated that 43% of them used social media. In contrast, TV was more prominent among them, with participants' characteristics such as living with parents, body mass index, and country of residence showing no association with NK. However, female sex, education, and reading nutrition articles are significantly correlated with adequate knowledge (p < 0.001). Significant predictors of satisfactory knowledge were age, sex, education, living with parents, and reading nutrition articles. CONCLUSION: The study revealed low levels of NK indicating an urgent need to implement educational programs to promote nutrition knowledge. As NK is a modifiable determinant of diet intake and can positively impact the need for developing strategies in counselling and raising awareness among the general population to improve their health status.

RESUMEN

The present study intends to investigate the performance of the Fenton reaction as one of the most efficient (AOPs) in a batch mode for treating wastewater effluent from the edible oil industry, as well as the parameters that influence the reaction, such as pH, hydrogen peroxide (H2O2), and ferrous sulfate heptahydrate (FeSO4.7H2O) doses at various reaction times. The response surface methodology (RSM) was applied with a central composite design (CCD) for optimizing the responses of pollutant removals. The obtained results indicated that the authenticated response to the chemical oxygen demand (COD) removal was 93.52%, at optimum values of pH, FeSO4.7H2O dose, H2O2 dose, and reaction time of 3, 1 g/L, 8.38 g/L, and 50 min, respectively. Furthermore, the authenticated response to oil and grease (O&G) removal was 99.8%, at optimum values of pH, FeSO4.7H2O dose, H2O2 dose, and reaction time of 3, 0.71 g/L, 8.7 g/L, and 37.4 min, respectively. Under these conditions, the residual COD and O&G after Fenton oxidation become 155.4 mg/L and 10 mg/L, respectively.

RESUMEN

OBJECTIVES: To evaluate the incidence of vascular complication and major bleeding in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) with a fully trans-wrist access (TWA) approach versus a conventional approach based on trans-femoral access (TFA). BACKGROUND: TFA is the preferred vascular access in CTO PCI, but it has been associated with a non-negligible risk of complications. METHODS: This retrospective registry included all patients undergoing CTO PCI at five institutions between July 2011 and October 2018. Patients were divided into two groups: Conventional (patients treated with at least one TFA) and Fully TWA (subjects exclusively treated with one or two TWA). The primary safety endpoint was a composite of vascular complications and major bleeding. The primary efficacy endpoint was procedural success. RESULTS: We included 1,900 patients (Conventional n = 1,496 and Fully TWA n = 404). Conventional patients showed higher occlusion complexity (J-CTO score 2.1 ± 1.2 vs. 1.5 ± 1.1, p < .001). Procedural success showed no significant difference between both groups (85.7 vs. 83.0%, p = .17). The primary safety endpoint occurred more frequently in the Conventional group (10.3 vs. 4.5%, p < .001), driven by vascular complications (9.4 vs. 3.7%, p < .001). On multivariate analysis, not using a Fully TWA approach was an independent predictor of the study endpoint, after adjusting for age, sex, diabetes, body mass index, chronic kidney disease, prior coronary artery bypass graft, and J-CTO score. CONCLUSIONS: Embracing a Fully TWA approach for CTO PCI might be associated with lower incidence of a composite endpoint of vascular complications and major bleeding, compared with a Conventional approach.

RESUMEN

This study aimed to: (i) characterize cultured granulosa cells (GCs) from different follicle sizes morphologically and molecularly; and (ii) select a suitable model according to follicular size that maintained GC function during culture. Buffalo ovaries were collected from a slaughterhouse and follicles were classified morphologically into: first group ≤ 4 mm, second group 5-8 mm, third group 9-15 mm and fourth group 16-20 mm diameter. GC pellets were divided into two portions. The first portion served as the control fresh pellet, and the secondwas used for 1 week for GC culture. Total RNA was isolated, and qRT-PCR was performed to test for follicle-stimulating hormone receptor (FSHR), cytochrome P450 19 (CYP19), luteinizing hormone/choriogonadotropin receptor (LHCGR), proliferating cell nuclear antigen (PCNA), apoptosis-related cysteine peptidase (CASP3), anti-Müllerian hormone (AMH), and phospholipase A2 group III (PLA2G3) mRNAs. Estradiol (E2) and progesterone (P4) levels in the culture supernatant and in follicular fluids were measured using enzyme-linked immunosorbent assay (ELISA). Basic DMEM-F12 medium maintained the morphological appearance of cultured GCs. The relative abundance of FSHR, CYP19, and LHCGR mRNAs was 0.001 ≤ P ≤ 0.01 and decreased at the end of culture compared with the fresh pellet. There was a fine balance between expression patterns of the proliferation marker gene (PCNA) and the proapoptotic marker gene (CASP3). AMH mRNA was significantly increased (P < 0.001) in cultured GCs from small follicles, while cultured GCs from other three categories (5-8 mm, 9-15 mm and 16-20 mm) showed a clear reduction (P < 0.001). Interestingly, the relative abundance of PLA2G3 mRNA was significantly (P < 0.001) increased in all cultured GCs. E2 and P4 concentrations were significantly (P < 0.001) decreased in all cultured groups. Primary cultured GCs from small follicles could be a good model for better understanding follicular development in Egyptian buffaloes.

RESUMEN

In the attempt to reduce the negative impacts of chemical pesticides on environment and consumer's health, a new plant treatment practice minimizing the amount of pesticides needed during pests and diseases treatments has been developed. Our approach is based on combining the biocide effects of fungicide with the peroxyacetic acid (PAA) one. In this paper, we focused on the in vitro study of the antifungal activity of this combination against Botrytis cinerea, the most redoubtable threat of tomatoes plants in Morocco. First, different concentrations of a peroxyacetic acid product (PERACLEAN®5) and two commercially available fungicides SWITCH and SIGNUM were tested separately for their inhibitory effects on the mycelial growth and spores germination of B. cinerea. 100% inhibition of fungal growth was achieved using 16.77 and 14.47 µg/ml of SIGNUM and SWITCH respectively and 1.5% of PERACLEAN®5. When combined with 0.5% of the peroxyacetic acid mixture (PERACLEAN®5), the pesticides 100% effective concentrations decreased to 0.5 µg/ml for both pesticides. Hence, this approach allowed us to suppress the pathogen while minimizing the amounts of applied fungicides by more than 95%.

RESUMEN

The aim of the present study was to evaluate the effects of supplementation of semen extender with various non-enzymatic antioxidants on the quality of cooled or cryopreserved Arabian stallion spermatozoa. Semen collected from four pure Arabian stallions was centrifuged at 600g for 15 min. Spermatozoa were then diluted in INRA-82 extender supplemented with bovine serum albumin (BSA; 0, 10, 15 and 20 mg/mL) or trehalose (0, 75, 100 and 150 mM) or zinc sulphate (0, 100, 150 and 200 µM). The diluted semen was then either cooled at 5 °C or cryopreserved in 0.5-ml plastic straws. After cooling or thawing, sperm motility, viability, sperm abnormalities, viability index, and plasma membrane integrity were evaluated. The results showed that supplementation of semen extender with 150 mM trehalose or with 200 µM zinc sulphate significantly (P < 0.05) improved motility, viability, sperm membrane integrity and acrosome status in Arabian stallion spermatozoa after cooling or after freezing and thawing compared with controls (non-supplemented media) or with those supplemented with other concentrations of trehalose or zinc sulphate. Supplementation of semen extender with BSA did not improve sperm motility or cryosurvival of Arabian stallion spermatozoa after cooling or after freezing and thawing. In conclusion, supplementation of semen extender with non-enzymatic antioxidants (trehalose or zinc sulphate) improved the quality of chilled and frozen/thawed Arabian stallion spermatozoa. The most beneficial effects occur when semen diluent was supplemented with 150 mM trehalose or 200 µM zinc sulphate.

RESUMEN

Alum recovery from water treatment sludge is a promising technique applied to decrease usage of fresh coagulants in the water treatment industry. In addition, alum recovery reduces sludge volume for easy handling. The undertaken work investigated the parametric conditions for alum recovery procedure by acidification. The results show that alum recovery reaches up to 69.03%, and the reduction of sludge volume reaches its highest level at 90%. Moreover, results of the parametric investigation reveal that the mixing time of 60 minutes and mixing intensity of 150 rpm are the optimum conditions of mixing for alum recovery from water treatment sludge. The optimum pH level is 1.50 for alum recovery as indicated by maximum aluminum releasing, maximum reduction of sludge volume, and reasonable dosages of added sulfuric acid.

RESUMEN

BACKGROUND: The prognostic impact of contrast-associated acute kidney injury (CA-AKI) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) remains underestimated. METHODS: We examined 2707 consecutive procedures performed in a referral CTO center between 2015 and 2019. CA-AKI was defined as an increase in serum creatinine ≥ 0.3 mg/dL or ≥ 50% within 48 h post-PCI. Primary endpoints were in-hospital major adverse cardiac and cerebrovascular events (MACCE, composite of all-cause death, myocardial infarction, target vessel revascularization, stroke) and at one year of follow-up. RESULTS: The overall incidence of CA-AKI was 11.5%. Technical success was comparable (87.2% vs. 90.5%, p = 0.056) whereas procedural success was lower in the CA-AKI group (84.3% vs. 89.7%, p = 0.004). Overall in-hospital MACCE was 1.3%, and it was similar in patients with and without CA-AKI (1.6% vs. 1.3%, p = 0.655); however, the rate of pericardial tamponade requiring pericardiocentesis was significantly higher in patients with CA-AKI (2.2% vs. 0.5%, p = 0.001). In multivariate analysis, CA-AKI was not independently associated with higher risk for in-hospital MACCE (adjusted odds ratio [OR] 1.34, 95% confidence intervals [CI] 0.45-3.19, p = 0.563). At a median follow-up time of 14 months (interquartile range [IQR], 11 to 35 months), one-year MACCE was significantly higher in patients with vs. without CA-AKI (20.8% vs. 12.8%, p < 0.001), and CA-AKI increased the risk for one-year MACCE (adjusted hazard ratio [HR] 1.46, 95% CI 1.07-1.95, p = 0.017) following CTO PCI. CONCLUSIONS: CA-AKI in patients undergoing CTO PCI occurs in approximately one out of 10 patients. Our study highlights that patients developing CA-AKI are at increased risk for long-term MACCE.

RESUMEN

AIMS: This study sought to determine the prognostic impact of acute decompensated heart failure (ADHF) in patients with heart failure with mildly reduced ejection fraction (HFmrEF). ADHF is a major complication in patients with heart failure (HF). However, the prognostic impact of ADHF in patients with HFmrEF has not yet been clarified. METHODS AND RESULTS: Consecutive patients hospitalized with HFmrEF (i.e. left ventricular ejection fraction 41-49% and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. The prognosis of patients with ADHF was compared with those without (i.e. non-ADHF). The primary endpoint was long-term all-cause mortality. Secondary endpoints included in-hospital all-cause mortality and long-term HF-related re-hospitalization. Kaplan-Meier, multivariable Cox proportional regression, and propensity score matched analyses were performed for statistics. Long-term follow-up was set at 30 months. A total of 2184 patients with HFmrEF were included, ADHF was present in 22%. The primary endpoint was higher in ADHF compared to non-ADHF patients with HFmrEF [50% vs. 26%; hazard ratio (HR) = 2.269; 95% confidence interval (CI) 1.939-2.656; P = 0.001]. Accordingly, the secondary endpoint of long-term HF-related re-hospitalization was significantly higher (27% vs. 10%; HR = 3.250; 95% CI 2.565-4.118; P = 0.001). A history of previous ADHF before the index hospitalization was associated with higher rates of long-term HF-related re-hospitalization (42% vs. 23%; HR = 2.073; 95% CI 1.420-3.027; P = 0.001), but not with long-term all-cause mortality (P = 0.264). CONCLUSION: ADHF is a common finding in patients with HFmrEF associated with an adverse impact on long-term prognosis.

RESUMEN

Cardiac remodeling is frequently observed in patients with heart failure (HF) and serves as an indicator of disease progression and severity. Septal hypertrophy represents an aspect of remodeling that can be easily assessed via an echocardiographic measurement of the interventricular septal end diastole (IVSd), but it has not been evaluated for its prognostic value, particularly in patients with heart failure with mildly reduced ejection fraction (HFmrEF). We retrospectively included 1881 consecutive patients hospitalized with HFmrEF (i.e., a left ventricular ejection fraction of 41-49% and signs and/or symptoms of HF) at one institution during a study period from 2016 to 2022. Septal hypertrophy, defined as an IVSd > 12 mm, was prevalent in 34% of the HFmrEF patients. Although septal hypertrophy was not associated with all-cause mortality at 30 months (median follow-up) (HR = 1.067; 95% CI: 0.898-1.267; p = 0.460), it was associated with an increased risk of hospitalization due to worsening HF at 30 months (HR = 1.303; 95% CI: 1.008-1.685; p = 0.044), which was confirmed even after multivariable adjustment (HR = 1.340; 95% CI: 1.002-1.792; p = 0.049) and propensity score matching (HR = 1.399; 95% CI: 1.002-1.951; p = 0.048). Although septal hypertrophy was not associated with the risk of all-cause mortality in patients with HFmrEF, it was identified as an independent predictor of long-term HF-related rehospitalization.

RESUMEN

OBJECTIVE: Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations. However, data regarding the prognostic impact in patients with cardiogenic shock (CS) is limited. The study investigates the prognostic impact of pre-existing TR in patients with CS. METHODS: Consecutive patients with CS from 2019 to 2021 were included in a monocentric registry. Every patient's medical history, including echocardiographic data, was recorded. The influence of pre-existing TR on prognosis was investigated. Furthermore, Kaplan-Meier analyses based on TR severity were conducted. Statistical analyses comprised univariable t-test, Spearman's correlation, Kaplan-Meier analyses, as well as multivariable Cox proportional regression models. Analyses were stratified by the underlying cause of CS such as acute myocardial infarction (AMI), or the need for mechanical ventilation. RESULTS: 105 patients with CS and pre-existing TR were included. In Kaplan Meier analyses, it could be demonstrated that patients with severe TR (TR III°) had the highest 30-day all-cause mortality compared to mild (TR I°) and moderate TR (TR II°) (44% vs. 52% vs. 77%; log rank p = .054). In the subgroup analyses of CS-patients without AMI, TR II°/TR III° showed a higher all-cause mortality after 30 days compared to TR I° (39% vs. 64%; log rank p = .027). In multivariable Cox regression TR II°/TR III° was associated with 30-day all-cause mortality in CS-patients without AMI (HR = 2.193; 95% CI 1.007-4.774; p = .048). No significant difference could be found in the AMI group. Furthermore, TR II°/III° was linked to an increased 30-day all-cause mortality in non-ventilated CS-patients (6% vs. 50%, log rank p = .015), which, however, could not be confirmed in multivariable Cox regression. CONCLUSION: The occurrence of pre-existing TR II°/III° was independently related with 30-day all-cause mortality in CS-patients without AMI. However, no prognostic influence was observed in CS-patients with AMI.

RESUMEN

BACKGROUND: Although mitral valve regurgitation (MR) is a common valvular heart disease in patients with heart failure (HF), there is a paucity of data on the characterization and outcomes of patients with HF with mildly reduced ejection fraction (HFmrEF) and concomitant MR. METHODS: From 2016 to 2022, consecutive patients hospitalized with HFmrEF (i.e., left ventricular ejection fraction from 41% to 49% and signs and/or symptoms of HF) were retrospectively included at one institution. Patients with MR were compared with patients without MR. Further risk stratification was performed according to MR severity and etiology (i.e., primary vs. secondary MR). The primary end point was all-cause mortality at 30 months (median follow-up), and the key secondary end point was hospitalization for worsening HF. RESULTS: Of 2181 patients hospitalized with HFmrEF, 59% presented with mild, 10% with moderate, and 2% with severe MR. MR was associated with increased all-cause mortality at 30 months (HR = 1.756; 95% CI 1.458-2.114; p = 0.001), with higher risk in more advanced stages. Furthermore, MR patients had higher risk of HF-related re-hospitalization at 30 months (HR = 1.560; 95% CI 1.172-2.076; p = 0.002). Even after multivariable adjustment, mild, moderate, and severe MR were still associated with all-cause mortality. Finally, the risk of all-cause mortality was lower in patients with secondary MR compared with patients with primary MR (HR = 0.592; 95% CI 0.366-0.956; p = 0.032). CONCLUSION: MR is common in HFmrEF and independently associated with higher risk of all-cause mortality and HF hospitalization.

RESUMEN

AIMS: As there is limited evidence regarding the prognostic impact of prior left ventricular ejection fraction (LVEF) in patients with heart failure with mildly reduced ejection fraction (HFmrEF), this study investigates the prognostic impact of longitudinal changes in LVEF in patients with HFmrEF. METHODS: Consecutive patients with HFmrEF (i.e. LVEF 41-49% with signs and/or symptoms of HF) were included retrospectively in a monocentric registry from 2016 to 2022. Based on prior LVEF, patients were categorized into three groups: stable LVEF, improved LVEF, and deteriorated LVEF. The primary endpoint was 30-months all-cause mortality (median follow-up). Secondary endpoints included in-hospital and 12-months all-cause mortality, as well as HF-related rehospitalization at 12 and 30 months. Kaplan-Meier and multivariable Cox proportional regression analyses were applied for statistics. RESULTS: Six hundred eighty-nine patients with HFmrEF were included. Compared to their prior LVEF, 24%, 12%, and 64% had stable, improved, and deteriorated LVEF, respectively. None of the three LVEF groups was associated with all-cause mortality at 12 (p ≥ 0.583) and 30 months (31% vs. 37% vs. 34%; log rank p ≥ 0.376). In addition, similar rates of 12- (p ≥ 0.533) and 30-months HF-related rehospitalization (21% vs. 23% vs. 21%; log rank p ≥ 0.749) were observed. These findings were confirmed in multivariable regression analyses in the entire study cohort. CONCLUSION: The transition from HFrEF and HFpEF towards HFmrEF is very common. However, prior LVEF was not associated with prognosis, likely due to the persistently high dynamic nature of LVEF in the follow-up period.

RESUMEN

BACKGROUND: The spectrum of patients with cardiogenic shock (CS) has changed significantly over time. CS has become especially more common in the absence of acute myocardial infarction (AMI), while this subset of patients was typically excluded from recent studies. Furthermore the prognostic impact of onset time and onset place due to CS has rarely been investigated. RESEARCH QUESTION: Do the place of CS onset (out-of-hospital, ie, primary CS vs in-hospital, ie, secondary CS) and the onset time of out-of-hospital CS (ie, on-hours vs off-hours admission) affect the risk of all-cause mortality at 30 days? STUDY DESIGN AND METHODS: This prospective monocentric registry included consecutive patients with CS of any cause from 2019 until 2021. First, the prognostic impact of the place of CS onset (out-of-hospital, ie, primary CS vs during hospitalization, ie, secondary CS) was investigated. Thereafter, the prognostic impact of the onset time of out-of-hospital CS was investigated. Furthermore, the prognostic impact of causative AMI vs non-AMI was investigated. Statistical analyses included Kaplan-Meier analyses, and univariable and multivariable Cox regression analyses. RESULTS: Two hundred seventy-three patients with CS were included prospectively (64% with primary out-of-hospital CS). The place of CS onset was not associated with increased risk of all-cause mortality within the entire study cohort (secondary in-hospital CS: hazard ratio [HR], 1.532; 95% CI, 0.990-2.371; P = .06). However, increased risk of 30-day all-cause mortality was seen in patients with AMI related secondary in-hospital CS (HR, 2.087; 95% CI, 1.126-3.868; P = .02). Furthermore, primary out-of-hospital CS admitted during off-hours was associated with lower risk of all-cause mortality compared to primary CS admitted during on-hours (HR, 0.497; 95% CI, 0.302-0.817; P = .01), irrespective of the presence or absence of AMI. INTERPRETATION: Primary and secondary CS were associated with comparable, whereas primary out-of-hospital CS admitted during off-hours was associated with lower risk of all-cause mortality at 30 days.

RESUMEN

Limited data concerning the diagnostic and prognostic value of blood-derived biomarkers in heart failure with mildly reduced ejection fraction (HFmrEF) is available. This study investigates the diagnostic and prognostic value of aminoterminal prohormone of brain natriuretic peptide (NT-proBNP) in patients with HFmrEF, stratified by the estimated glomerular filtration rate (eGFR). Consecutive patients with HFmrEF were retrospectively included at one institution from 2016 to 2022. First, the diagnostic value of NT-proBNP for acute decompensated heart failure (ADHF) was tested. Thereafter, the prognostic value of NT-proBNP levels was tested for 30-months all-cause mortality in patients with ADHF. From a total of 755 patients hospitalized with HFmrEF, the rate of ADHF was 42%. Patients with ADHF revealed higher NT-proBNP levels compared to patients without (median 5394 pg/mL vs. 1655 pg/mL; p = 0.001). NT-proBNP was able to discriminate ADHF with an area under the curve (AUC) of 0.777 (p = 0.001), with the highest AUC in patients with eGFR ≥ 60 mL/min (AUC = 0.800; p = 0.001), and no diagnostic value was seen in eGFR < 30 mL/min (AUC = 0.576; p = 0.210). Patients with NT-proBNP levels > 3946 pg/mL were associated with higher rates of all-cause mortality at 30 months (57.7% vs. 34.4%; HR = 2.036; 95% CI 1.423-2.912; p = 0.001), even after multivariable adjustment (HR = 1.712; 95% CI 1.166-2.512; p = 0.006). In conclusion, increasing NT-proBNP levels predicted the risk of ADHF and all-cause mortality in patients with HFmrEF and preserved renal function; however, NT-proBNP levels were not predictive in patients with HFmrEF and eGFR < 30 mL/min.

RESUMEN

OBJECTIVE: The study investigates the prognosis of atrial fibrillation (AF) in patients with heart failure with mildly reduced ejection fraction (HFmrEF). BACKGROUND: Data concerning the prognostic impact of AF in patients with HFmrEF is scarce. METHODS: Consecutive patients with HFmrEF (i.e., left ventricular ejection fraction 41-49% and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. Patients with AF were compared to patients without with regard to the primary composite endpoint of all-cause mortality and HF-related rehospitalization at 30 months (median follow-up). Statistical analyses included Kaplan-Meier analyses, multivariable Cox proportional regression analyses and propensity score matching. RESULTS: 2,148 patients with HFmrEF were included with an overall prevalence of AF of 43%. The presence of AF was associated with higher risk of the primary composite endpoint all-cause mortality and HF-related rehospitalization at 30 months (HR = 2.068; 95% CI 1.802-2.375; p = 0.01), which was confirmed after propensity-score matching (HR = 1.494; 95% CI 1.216-1.835; p = 0.01). AF was an independent predictor of both all-cause mortality (HR = 1.340; 95% CI 1.066-1.685; p = 0.01) and HF-related rehospitalization (HR = 2.061; 95% CI 1.538-2.696; p = 0.01). Finally, rhythm control may be associated with lower risk of all-cause mortality compared to rate control for AF (HR = 0.342; 95% CI 0.199-0.587; p = 0.01). CONCLUSION: AF affects 43% of patients with HFmrEF and represents an independent predictor of adverse long-term prognosis.


By now, limited data regarding the prognostic impact of comorbidities in heart failure with mildly reduced ejection fraction (HFmrEF) is available, contributing to the overall limited evidence regarding the treatment of patients with HFmrEF. The present study investigates the prognostic impact of the presence of atrial fibrillation (AF) on the long-term prognosis of patients with HFmrEF using a large retrospective study of 2,148 patients hospitalized with HFmrEF from 2016 to 2022. AF was prevalent in 43% of patients with HFmrEF and independently associated with an increased risk of the composite of long-term all-cause mortality and HF-related rehospitalization. Adverse prognosis in patients with concomitant AF was confirmed using multivariable Cox regression analyses and propensity score matching. Finally, the achievement of rhythm control may be associated with a lower risk of long-term all-cause mortality. Further studies are needed to demonstrated the effect of rhythm control and catheter ablation for AF in patients with HFmrEF.

RESUMEN

BACKGROUND: The aging population has led to a significant increase in heart failure (HF) patients. Related to demographic changes, the burden with comorbidities was shown to increase in patients with HF. Whereas chronic obstructive pulmonary disease (COPD) was yet demonstrated to be associated with adverse outcomes in patients with HF, the prognostic impact of COPD in HF with mildly reduced ejection fraction (HFmrEF) has not yet been clarified. OBJECTIVE: The study investigates the prognostic impact of COPD in patients hospitalized with HFmrEF. METHODS: Consecutive patients with HFmrEF were retrospectively included at one institution from 2016 to 2022. Patients with COPD were compared to patients without with regard to the primary endpoint all-cause mortality at 30 months (median follow-up). Secondary endpoints comprised in-hospital mortality, HF-related re-hospitalization, cardiac re-hospitalization and major adverse cardiac and cerebrovascular events (MACCE) at 30 months. RESULTS: A total of 2184 patients with HFmrEF were included with a prevalence of COPD of 12.0 %. Patients with COPD were older (median 77 vs. 75 years; p = 0.025), had increased burden of cardiovascular comorbidities and more advanced HF symptoms. At 30 months, patients with COPD had an increased risk of all-cause mortality compared to patients without (45 % vs. 30 %; HR = 1.667; 95 % CI 1.366-2.034; p = 0.001), alongside with a higher risk of re-hospitalization for worsening HF (20 % vs. 12 %; HR = 1.658; 95 % CI 1.218-2.257; p = 0.001). CONCLUSION: COPD is independently associated with adverse outcomes in patients hospitalized with HFmrEF.

RESUMEN

Bifurcation involvement close to or within the occluded segment poses increasing difficulties for chronic total occlusion (CTO)-percutaneous coronary intervention (PCI). However, this variable is not considered in the angiography-based CTO scoring systems nor has been extensively investigated in large multicenter series. Accordingly, we analyzed a CTO-PCI registry involving 92 European centers to explore the incidence, angiographic and procedural characteristics, and outcomes specific to CTO-PCIs with bifurcation involvement. A total of 3,948 procedures performed between January and November 2023 were examined (33% with bifurcation involvement). Among bifurcation lesions, 38% and 37% were located within 5 mm of the proximal and distal cap, respectively, 16% within the CTO body, and in 9% of cases proximal and distal bifurcations coexisted. When compared with lesions without bifurcation involvement, CTO bifurcation lesions had higher complexity (J-CTO 2.33 ± 1.21 vs 2.11 ± 1.27, p <0.001) and were associated with higher use of additional devices (dual-lumen microcatheter in 27.6% vs 8.4%, p <0.001, and intravascular ultrasound in 32.2% vs 21.7%, p <0.001). Radiation dose (1,544 [836 to 2,819] vs 1,298.5 [699.1 to 2,386.6] mGy, p <0.001) and contrast volume (230 [160 to 300] vs 190 [130 to 250] ml, p <0.001) were also higher. Technical success was similar (91.5% with bifurcation involvement vs 90.4% without bifurcation involvement, p = 0.271). However, the bifurcation lesions within the CTO segment (intralesion) were associated with lower technical success than the other bifurcation-location subgroups (83.7% vs 93.3% proximal, 93.4% distal, and 89.0% proximal and distal, p <0.001). On multivariable analysis, the presence of an intralesion bifurcation was independently associated with technical failure (odds ratio 2.04, 95% confidence interval 1.24 to 3.35, p = 0.005). In conclusion, bifurcations are present in approximately one-third of CTOs who underwent PCI. PCI of CTOs with bifurcation can be achieved with high success rates except for bifurcations within the occluded segment, which were associated with higher technical failure.

RESUMEN

BACKGROUND: Percutaneous coronary interventions (PCI) of chronic total occlusions (CTO) have reached high procedural success rates thanks to dedicated equipment, evolving techniques, and worldwide adoption of state-of-the-art crossing algorithms. AIMS: We report the contemporary results of CTO PCIs performed by a large European community of experienced interventionalists. Furthermore, we investigated the impact of different risk factors for procedural major adverse cardiac and cerebrovascular events (MACCE) and trends of employment of specific devices like dual lumen microcatheters, guiding catheter extensions, intravascular ultrasound and calcium-modifying tools. METHODS: We evaluated data from 8,673 CTO PCIs included in the European Registry of Chronic Total Occlusion (ERCTO) between January 2021 and October 2022. RESULTS: The overall technical success rate was 89.1% and was higher in antegrade as compared with retrograde cases (92.8% vs 79.3%; p<0.001). Compared with antegrade procedures, retrograde procedures had a higher complexity of attempted lesions (Japanese CTO [J-CTO] score: 3.0±1.0 vs 1.9±1.2; p<0.001), a higher procedural and in-hospital MACCE rate (3.1% vs 1.2%; p<0.018) and a higher perforation rate with and without tamponade (1.5% vs 0.4% and 8.3% vs 2.1%, respectively; p<0.001). As compared with mid-volume operators, high-volume operators had a higher technical success rate in antegrade and retrograde procedures (93.4% vs 91.2% and 81.5% vs 69.0%, respectively; p<0.001), and had a lower MACCE rate (1.47% vs 2.41%; p<0.001) despite a higher mean complexity of the attempted lesions (J-CTO score: 2.42±1.28 vs 2.15±1.27; p<0.001). CONCLUSIONS: The adoption of different recanalisation techniques, operator experience and the use of specific devices have contributed to a high procedural success rate despite the high complexity of the lesions documented in the ERCTO.
