RESUMEN
BACKGROUND: Echocardiographic prognostic indicators of precapillary pulmonary hypertension (PH) mortality has been inconclusive. This study aims to examine the prognostic values of right ventricular echocardiographic functional parameters in predicting precapillary PH mortality. METHODS: Systematic searches were conducted in the ScienceDirect, Medline, and Cochrane databases for longitudinal studies. Assessments included means and hazard ratios (HRs) for Tricuspid Annular Plane Systolic Excursion (TAPSE), Right Ventricular Systolic Pressure (RVSP), Right Ventricular Longitudinal Strain (RVLS), Right Ventricular Fractional Area Change (RVFAC), Right Ventricular Ejection Fraction (RVEF), and Right Ventricular Index of Myocardial Performance (RIMP). RESULTS: The meta-analysis included 24 cohort studies comprising 2171 participants. Mean values were as follows: TAPSE 17.62 mm, RVSP 77.50 mmHg, RVLS - 16.78%, RVFAC 29.81%, RVEF 37.56%, and RIMP 0.52. TAPSE (HR: 1.28; 95% CI 1.17-1.40; p < 0.001), RVLS (HR: 1.74; 95% CI 1.34-2.26; p < 0.001), RVFAC (HR: 1.40; 95% CI 1.13-1.75; p < 0.001), RVEF (HR: 1.08; 95% CI 1.02-1.15; p = 0.01), and RIMP (HR: 1.51; 95% CI 1.23-1.86; p < 0.001) emerged as significant prognosticators of precapillary PH mortality, with the exception of RVSP (HR: 1.04; 95% CI 0.99-1.09; p = 0.14). TAPSE summary receiver operating characteristics (sROC) analysis yielded an area under the curve (AUC) of 0.85 [95% CI 0.81-0.88] with a sensitivity of 0.81 [95% CI 0.63-0.91] and a specificity of 0.74 [95% CI 0.54-0.87]. RVLS sROC resulted in an AUC of 0.74 [95% CI 0.70-0.78] with a sensitivity of 0.74 [95% CI 0.57-0.86] and a specificity of 0.69 [95% CI 0.64-0.75]. CONCLUSIONS: TAPSE, RVLS, RVFAC, RVEF, and RIMP demonstrated promise as valuable prognostic indicators for precapillary PH mortality.
RESUMEN
BACKGROUND: Atrial fibrillation (AF) poses a significant stroke risk in heart disease patients. This systematic review aims to evaluate the efficacy and safety of non-vitamin K oral antagonists (NOACs) versus vitamin K antagonists (VKAs) in AF patients with and without any valvular heart disease (VHD/N-VHD). METHODS: A systematic search was conducted on PubMed, Scopus, and Google Scholar up to March 3, 2022. Efficacy and safety parameters were analyzed. RESULTS: A total of 85,423 subjects from 10 studies were included in this meta-analysis. NOACs and VKAs showed similar effects on ischemic stroke in AF patients with VHD/N-VHD (RR 0.97; 95% CI 0.72-1.30; p = 0.83) and also on systemic embolic events (RR 1.02; 95% CI 0.83-1.25; p = 0.86). Similar effects were seen in VHD and N-VHD subgroups. Both treatments had similar effects on myocardial infarction in AF patients with VHD/N-VHD (RR 0.79; 95% CI 0.49-1.26; p = 0.32), VHD (RR 0.78; 95% CI 0.59-1.02; p = 0.07), and N-VHD subgroups (RR 0.82; 95% CI 0.30-2.21; p = 0.69). NOACs reduced the risk of intracranial bleeding in AF VHD/N-VHD (RR 0.64; 95% CI 0.54-0.77; p < 0.0001), VHD (RR 0.59; 95% CI 0.42-0.82; p = 0.002), and N-VHD subgroups (RR 0.70; 95% CI 0.57-0.85; p = 0.0003). Additionally, NOACs reduced the risk of gastrointestinal bleeding in AF VHD/N-VHD (RR 0.80; 95% CI 0.66-0.96; p = 0.02), specifically in the VHD subgroup (RR 0.69; 95% CI 0.54-0.89; p = 0.004). Moreover, NOACs were associated with a decreased risk for minor and non-fatal bleeding in AF patients with VHD/N-VHD (RR 0.86; 95% CI 0.75-0.99; p = 0.04). CONCLUSION: NOACs are effective and safe for ischemic stroke, systemic embolic events, myocardial infarction, intracranial bleeding, and gastrointestinal bleeding in AF patients with VHD/N-VHD.
RESUMEN
Background: Ventricular tachycardia (VT) remains a risk in repaired Tetralogy of Fallot (rTOF); however, long-term benefits of VT ablation have not been established. This study compares the outcomes of rTOF patients with and without VT ablation. Methods: We searched multiple databases examining the outcomes of rTOF patients who had undergone VT ablation compared to those without ablation. Primary outcomes were VT recurrence, sudden cardiac death (SCD), and all-cause mortality. Subgroup analysis was conducted based on the type of ablation (catheter and surgical). Slow-conducting anatomical isthmus (SCAI)-based catheter ablation (CA) was also analyzed separately. The secondary outcome was the risk factors for the pre-ablation history of VT. Results: Fifteen cohort studies with 1459 patients were included, 21.4% exhibited VTs. SCAI was found in 30.4% of the population, with 3.7% of non-inducible VT. Factors significantly associated with VT before ablation included a history of ventriculostomy, QRS duration ≥180 ms, fragmented QRS, moderate to severe pulmonary regurgitation, high premature ventricular contractions burden, late gadolinium enhancement, and SCAI. Ablation was only beneficial in reducing VTs recurrence in SCAI-based CA (risk ratio (RR) 0.11; 95% CI 0.03 to 0.33. p < 0.001; I2 = 0%) with no recurrence in patients with preventive ablation (mean follow-up time 91.14 ± 77.81 months). The outcomes of VT ablation indicated a favorable trend concerning SCD and all-cause mortality (RR 0.49 and 0.44, respectively); however, they were statistically insignificant. Conclusions: SCAI-based CA has significant advantages in reducing VT recurrence in rTOF patients. Risk stratification plays a key role in determining the decision to perform ablation.
RESUMEN
Background: Catheter ablation in the pediatric population using fluoroscopy has been known to cause adverse events. This study aims to assess the effectiveness and safety of zero fluoroscopy (ZF) and near-ZF-guided catheter ablation for the treatment of arrhythmias in the pediatric population. Methods: The PubMed, Embase, and Cochrane library databases were searched and reviewed for relevant studies. Outcomes of interest include safety, short-term, and long-term effectiveness. We classified patients ≤21 years old who underwent ZF or near-ZF ablation with fluoroscopy time ≤1.5 min as our study group and patients within the same age range who underwent conventional fluoroscopy and/or near-ZF ablation with a mean fluoroscopy time >1.5 min as our control group. Both ZF and near-ZF ablation utilized 3D-electroanatomical mapping (3D-EAM). Results: Ten studies composed of 2279 patients were included in this study. Total fluoroscopy time (MD -15.93 min, 95% CI (-22.57 - (-9.29), p < .001; I 2 = 84%)) and total procedural time (MD -22.06 min, 95% CI (-44.39 - (-0.28), p < .001; I 2 = 88%)) were significantly lower in the near-ZF group. Both ZF and near-ZF demonstrated a trend towards improved success rates compared to conventional fluoroscopy but did not achieve statistical significance for all subgroup analyses. Ablation in the study group also decreased incidence of complication compared to the control (RR 0.35; 95% CI (0.14-0.90); p = .03; I 2 = 0%). Conclusion: ZF and near-ZF ablation reduced the overall duration, compares in effectiveness, and shows a superior safety profile compared to control group.
RESUMEN
BACKGROUND: Transarterial embolization (TAE) is pivotal in managing non-cavernous and cavernous sinus dural arteriovenous fistulas (CSDAVFs). METHODS: Systematic searches were conducted across ScienceDirect, Medline, and Cochrane databases for longitudinal studies on TAE outcomes in non-CSDAVFs and CSDAVFs. Post-procedural outcomes, including complete, incomplete, and failed AVFs obliteration, and end-study outcomes were analyzed. RESULTS: Our meta-analysis involved 27 studies with 643 patients and 736 fistulas. Symptoms in both groups included tinnitus (29.74â¯%), ocular/visual symptoms (29.12â¯%), hemorrhage (19.42â¯%), and headache (19.11â¯%). Feeding arteries mainly originated from the meningeal arteries (49.16â¯%). In non-CSDAVFs cases, fistula locations were within sinus complexes (69.23â¯%) and specific dural areas (28.31â¯%). Complete AVFs obliteration was 81â¯% (95â¯%CI: 70â¯% - 90â¯%), slightly higher in non-CSDAVFs (82â¯%, 95â¯% CI: 69â¯% - 92â¯%) than CSDAVFs (79â¯%, 95â¯%CI: 58â¯% - 95â¯%). Incomplete obliteration occurred in 14â¯% (95â¯%CI: 5â¯% - 39â¯%), with rates of 11â¯% (95â¯%CI: 2â¯% - 26â¯%) in non-CSDAVFs and 19â¯% (95â¯% CI: 5â¯% - 39â¯%) in CSDAVFs. Failed obliteration was rare (1â¯%, 95â¯%CI: 0â¯% - 3â¯%), with similar rates in both groups. At end-study follow-up, resolution of AVFs was achieved in 97â¯% of cases (95â¯%CI: 92â¯% - 100â¯%). However, complications occurred in 17â¯% of cases (95â¯%CI: 10â¯% - 25â¯%), with a higher incidence in CSDAVFs (22â¯%, 95â¯%CI: 9â¯% - 37â¯%) compared to non-CSDAVFs (13â¯%, 95â¯%CI: 6â¯% - 23â¯%). CONCLUSIONS: TAE with embolic agents demonstrates favorable outcomes in non-CSDAVFs and CSDAVFs, with high rates of AVFs obliteration and resolution. Complications, particularly in CSDAVFs, warrant careful consideration in treatment decisions.
RESUMEN
The efficacy of drug-coated balloons (DCB) versus drug-eluting stents (DES) for coronary artery disease (CAD) remains inconclusive. Despite paclitaxel's common use in both DES and DCB, there is a lack of meta-analyses comparing paclitaxel-eluting stents (PES) and paclitaxel-coated balloons (PCB). This meta-analysis aimed to evaluate and compare the outcomes of DES and DCB with paclitaxel. A systematic literature search of the Medline and Cochrane databases yielded six randomized controlled trials with 951 patients (1:1 ratio). Primary endpoints were mortality, target lesion vascularization (TLV), myocardial infarction (MI), target vessel revascularization (TVR), and major adverse cardiovascular events (MACEs). Secondary endpoints included in-device binary stenosis, in-segment binary stenosis, late luminal loss (LLL), post-minimal lumen diameter (MLD), and post-diameter stenosis. Within the study populations, the incidence of previous MI was significantly lower in the PES group than in the PCB group (26.70% vs. 39.22%, OR:0.56, 95% CI [0.41-0.76], p = 0.0002). The meta-analysis results showed that mortality (OR:1.57, 95% CI [0.67-3.66], p = 0.29), TLV (OR:0.74, 95% CI [0.37-1.48], p = 0.39), MI (OR:1.76, 95% CI [0.79-3.88], p = 0.16), TVR (OR:0.76, 95% CI [0.51-1.12], p = 0.16), and MACEs (OR, 1.11; 95% CI [0.48-2.58]; p = 0.81) did not exhibit significant differences between the PES and PCB groups in CAD. Furthermore, in stent or in balloon binary stenosis (OR:0.80, 95% CI [0.34-1.87], p = 0.60), in segment binary stenosis (OR:1.16, 95% CI [0.48-2.80], p = 0.74), LLL (MD:0.03, 95% CI [-0.11 to 0.17], p = 0.65), post MLD (MD:0.04, 95% CI [-0.23 to 0.30], p = 0.77), and post diameter stenosis (MD:-5.48, 95% CI [-13.88 to 2.92], p = 0.20) were similar in both groups. Our comprehensive analysis concludes that both PES and PCB manifest comparable effectiveness and safety in CAD management.
RESUMEN
BACKGROUND: Stroke outcomes are multifactorial, and the C-Reactive Protein to Albumin Ratio (CAR) has emerged as a potential prognostic marker. This study aims to evaluate CAR prognostic significance in stroke. METHODS: Systematic searches across ScienceDirect, Medline, and Cochrane databases identified longitudinal studies. Unfavorable outcomes, including poor prognosis (modified rankin scale> 2), mortality, and severe complications like hemorrhage or restenosis, were considered. Analyses for unfavorable outcomes were conducted based on prior intervention, stroke type, and outcome type. RESULTS: The meta-analysis included 12 cohort studies comprising 5042 participants. Elevated CAR (OR: 1.72; 95% confidence interval [CI]: 1.17-2.52; P = 0.01) and CRP (OR: 1.91; 95% CI: 1.31-2.77; P < 0.001) levels on admission were associated with unfavorable outcomes; no such association was observed for albumin (OR: 0.66; 95%CI: 0.24-1.80; P = 0.42). Elevated CAR levels were associated with unfavorable outcomes in patients undergoing mechanical thrombectomy (odds ratio [OR]: 2.70; 95% CI: 1.14-6.38; P < 0.02) and those with ischemic stroke (OR: 1.99; 95% CI: 1.24-3.18; P < 0.001), but no significant association was found in patients with hemorrhagic stroke. Furthermore, concerning specific outcomes, high CAR levels were associated with mortality (OR: 1.71; 95% CI: 1.00-2.95; P = 0.05) and hemorrhage (OR: 6.02; 95% CI: 1.61-23.87; P = 0.05). The area under the curve for CAR was 0.72 (0.68-0.76), with a sensitivity of 0.61 (0.49-0.71) and specificity of 0.73 (0.64-0.81). CONCLUSIONS: Elevated CAR emerges as an effective marker in assessing unfavorable outcomes in stroke patients with moderately high sensitivity and specificity. High CAR levels exhibited statistically significant mortality and hemorrhage in stroke patients undergoing mechanical thrombectomy.

BACKGROUND: The impacts of single high-dose statin preloading in patients undergoing percutaneous coronary intervention (PCI) have not been fully examined. This study aims to evaluate post-procedure impacts of single high-dose statin pretreatment with acute coronary syndrome (ACS). METHODS: The meta-analysis reviewed Cochrane, PubMed, and Medline databases for studies comparing single high-dose atorvastatin or rosuvastatin to placebo in ACS patients undergoing PCI. The primary endpoints included major adverse cardiovascular events (MACE), myocardial infarction (MI), all-cause mortality, and target vessel revascularization (TVR) at three months. Secondary endpoints examined were the TIMI flow grade 3 and left ventricular ejection fraction (LVEF). RESULTS: Comprehensive analysis was conducted on fifteen RCTs, encompassing a total of 6,207 patients (3090 vs 3117 patients). The pooled results demonstrated that a single high-dose of statin administered prior to PCI led to a significant decrease in the incidence of MACE at three months post-PCI compared to the control group (OR 0.50, 95%CI 0.35-0.71, p = 0.0001). The occurrence of MI (OR 0.57, 95%CI 0.42-0.77, p = 0.0002), all-cause mortality (OR 0.56, 95%CI 0.39-0.81, p = 0.0002), and TVR (OR 0.56, 95%CI 0.35-0.92, p = 0.02) was significantly lower in the statin single high-dose group compared to the control group. No significant effects on TIMI flow grade 3 (OR 1.20, 95%CI 0.94-1.53, p = 0.14) or left ventricular ejection fraction (OR 2.19, 95%CI - 0.97 to 5.34, p = 0.17) were observed. Subgroup analysis demonstrated reduced incidence of MACE with a single dose of 80 mg atorvastatin (OR 0.66, 95%CI 0.54-0.81, p < 0.0001) and 40 mg rosuvastatin (OR 0.19, 95%CI 0.07-0.54, p = 0.002). CONCLUSIONS: Single high-dose statin before PCI in patients with ACS significantly reduces MACE, MI, all-cause mortality, and TVR three months post-PCI.
RESUMEN
INTRODUCTION: The optimal approach for pediatric ostium secundum atrial septal defect (ASD) closure remains uncertain. This study aims to assess complications and efficacies of surgical and transcatheter closures. METHODS: Systematic search in Medline, Cochrane, and EMBASE databases identified cohort studies until July 2023. Complications, length of hospital stay, and efficacy outcomes were evaluated. Subgroup analyses considered ethnicity, ASD size, age, and rim deficiency involvement. RESULTS: Fourteen cohort studies involving 9695 patients were comprehensively analyzed. Regarding complications, the pediatric patients in the surgery group exhibited higher occurrences of cardiac arrhythmia (odds ratio [OR]: 1.87, 95% confidence interval [CI]: 1.22-2.87, p=0.004), pericardial effusion (OR: 14.80, 95% CI: 6.97-31.43, p<0.00001), and pulmonary complications (OR: 2.58, 95% CI: 1.73-3.85, p<0.00001) compared with those in the transcatheter group. However, no significant difference in fever incidence was observed (OR: 2.57, 95% CI: 0.90-7.34, p=0.08). Furthermore, length of hospital stay was notably shorter in the pediatric transcatheter group (mean difference [MD]: 4.00, 95% CI: 1.71-6.29, p=0.0006). Regarding efficacies, both groups demonstrated similar rates of successful closure (OR: 1.97, 95% CI: 0.56-6.92, p=0.29) and residual shunting (OR: 0.55, 95% CI: 0.17-1.77, p=0.31) in the pediatric cohort. Subgroup analyses revealed that surgical residual shunting was notably lower in the European pediatric population (OR: 0.18, 95% CI: 0.07-0.45, p=0.0002), in cases with ASD size exceeding 15 mm (OR: 0.19, 95% CI: 0.08-0.49, p=0.0006), and in pediatric patients younger than 8 years (OR: 0.33, 95% CI: 0.12-0.92, p=0.03). Interestingly, residual shunting involving complex ASD with rim deficiency was more pronounced in the surgery group (OR: 2.66, 95% CI: 1.33-5.32, p=0.006). CONCLUSIONS: Both surgical and transcatheter closures are equally effective, with transcatheter closure showing significantly fewer complications. CLINICAL IMPACT: This meta-analysis offers pivotal insights for clinicians grappling with the optimal approach to pediatric ostium secundum ASD closure. The observed higher incidence of cardiac arrhythmias, pericardial effusions, and pulmonary complications in surgical closures underscores the challenges associated with this modality. In contrast, transcatheter closure, with its comparable efficacy and shorter hospital stays, emerges as an appealing and less invasive alternative. These findings equip clinicians with evidence to make informed decisions, optimizing patient outcomes. Subgroup analyses further refine recommendations, emphasizing tailored considerations for European pediatric patients, larger ASDs, and those under 8 years old, ultimately fostering personalized and improved care strategies.
RESUMEN
BACKGROUND: While serotonin norepinephrine reuptake inhibitors (SNRIs) offer promise in managing Post-surgical neuropathic pain (PSNP), uncertainties remain. This study aims to evaluate the effectiveness and adverse events of SNRIs in managing PSNP. METHODS: Systematic searches of PubMed, Embase, and Cochrane databases up to January 1st 2023 identified randomized controlled trials (RCTs) comparing SNRIs to placebo for PSNP. The primary outcome measures were pain at rest and adverse events post-surgery. Subgroup analyses were conducted based on surgical type and specific SNRIs. RESULTS: A total of 19 RCTs, encompassing 1440 participants (719 in the SNRI group vs 721 in the placebo group), met the inclusion criteria and were included. The pooled results demonstrated that pain scores were significantly lower in patients treated with SNRIs at 2â¯hours (MD:-0.26; 95%CI: -0.47 to -0.04; p=0.02), 6â¯hours (MD:-0.68; 95%CI: -1.01 to -0.34; p<0.0001), 24â¯hours (MD:-0.54; 95%CI: -0.99 to -0.09; p=0.02), and 48â¯hours (MD:-0.66; 95%CI: -1.23 to -0.10; p=0.02) post-surgery. In terms of adverse events, dizziness (OR:2.53; 95%CI: 1.34-4.78; p=0.004) and dry mouth (OR:2.21; 95%CI: 1.25-3.92; p=0.007) were significantly higher in the SNRIs group. Subgroup analysis showed that SNRI was found to significantly lower the 24-hour pain score after spinal surgery (MD:-0.45; 95%CI: -0.84 to -0.05; p=0.03). Duloxetine (MD:-0.63; 95%CI: -1.15 to -0.11; p=0.02) had a significant effect in lowering the 24-hour pain score at rest compared to placebo, whereas venlafaxine did not. CONCLUSIONS: SNRIs yielded considerable pain score reductions across multiple post-surgical intervals, although accompanied by an increased incidence of dizziness and dry mouth.

BACKGROUND AND OBJECTIVE: Brain arteriovenous malformations (bAVMs) carry a risk of hemorrhage. We aim to identify factors associated with subsequent hemorrhages. METHODS: Systematic searches were conducted across the ScienceDirect, Medline, and Cochrane databases. Assessed risk factors included bAVM size, bAVM volume, hemorrhage and seizure presentations, presence of deep venous drainage, deep-seated bAVMs, associated aneurysms, and Spetzler-Martin grade. Subgroup analyses were conducted on prior treatments, hemorrhage presentation, AVM size, and type of management. RESULTS: The meta-analysis included 8 cohort studies and 2 trials, with 4,240 participants. Initial hemorrhage presentation (HR 2.41; 95% CI 1.94-2.98; p < 0.001), any deep venous drainage (HR 1.52; 95% CI 1.09-2.13; p = 0.01), and associated aneurysms (HR 1.78; 95% CI 1.41-2.23; p < 0.001) increased secondary hemorrhage risk. Conversely, higher Spetzler-Martin grades (HR 0.77; 95% CI 0.68-0.87; p < 0.001) and larger malformation volumes (HR 0.87; 95% CI 0.76-0.99; p = 0.04) reduced risk. Subgroups showed any deep venous drainage in patients without prior treatment (HR 1.64; 95% CI 1.25-2.15; p < 0.001), bAVM > 3 cm (HR 1.79; 95% CI 1.15-2.78; p = 0.01), and multimodal interventions (HR 1.69; 95% CI 1.12-2.53; p = 0.01) increased risk. The reverse effect was found for patients initially presented without hemorrhage (HR 0.79; 95% CI 0.67-0.93; p = 0.01). Deep bAVM was a risk factor in > 3 cm cases (HR 2.72; 95% CI 1.61-4.59; p < 0.001) and multimodal management (HR 2.77; 95% CI 1.66-4.56; p < 0.001). Kaplan-Meier analysis revealed increased hemorrhage risk for initial hemorrhage presentation, while cumulative survival was higher in intervened patients over 72 months. CONCLUSION: Significant risk factors for bAVMs hemorrhage include initial hemorrhage, any deep venous drainage, and associated aneurysms. Deep venous drainage involvement is a risk factor in cases without prior treatment, those with bAVM > 3 cm, and cases managed with multimodal interventions. Deep bAVM involvement also emerges as a risk factor in cases > 3 cm and those managed with multimodal approaches.

Background: Ejection fraction (EF) is often used as a prognostic indicator and for classifying heart failure (HF) patients. This study evaluates the association of echocardiographic parameters with HF with improved EF (HFimpEF). Methods: This single-centre study retrospectively included patients with HF with reduced EF (HFrEF) from a cohort of admitted patients over 2018-2020, who were then followed up prospectively until 2023. The control group was categorized as patients with non-recovered HFrEF, and the population group was categorized as patients with HFimpEF. Results: A total of 176 patients with HFrEF were included in the study. Non-ischemic etiology was found to be the most prevalent cause of HFimpEF. The baseline echocardiography examination revealed that the HFimpEF group exhibited significantly higher values for tricuspid annular plane systolic excursion (TAPSE; P < 0.001) and inferior vena cava diameter (P < 0.001). The non-recovered HFrEF group demonstrated higher baseline left atrial volume index (LAVi) values (P < 0.001). In multivariate analysis, a higher value of TAPSE (odds ratio 3.071; P = 0.008) and a lower value of LAVi (odds ratio 2.034; P = 0.008) were independent echocardiography variables associated with HFimpEF. After a mean follow-up duration of 32.5 ± 9.1 months, the HFimpEF group had higher survival from rehospitalization due to worsening HF and lower all-cause mortality (log rank P < 0.001 and P = 0.005, respectively). Conclusions: Higher TAPSE and lower LAVi in baseline were associated with the transition from HFrEF to HFimpEF. The HFimpEF group had better survival compared to those with non-recovered HFrEF.
Contexte: La fraction d'éjection est souvent utilisée comme indicateur pronostique et comme élément de classification des patients atteints d'insuffisance cardiaque. La présente étude visait à évaluer l'association entre les paramètres échocardiographiques et l'insuffisance cardiaque avec fraction d'éjection améliorée (ICFEA). Méthodologie: Cette étude monocentrique a été menée de façon rétrospective auprès d'une cohorte de patients atteints d'insuffisance cardiaque avec fraction d'éjection réduite (ICFER) traités entre 2018 et 2020, et cette cohorte a été suivie de façon prospective jusqu'en 2023. Les patients du groupe témoin ont été classés comme ayant une ICFER ne s'étant pas résorbée, et les patients de la population étudiée ont été classés comme ayant une ICFEA. Résultats: Au total, 176 patients présentant une ICFER ont été inclus dans l'étude. La cause la plus fréquente d'ICFER était une étiologie non ischémique. Lors de l'évaluation échocardiographique initiale, les patients du groupe ayant progressé vers l'ICFEA présentaient des valeurs significativement plus élevées en ce qui concerne l'excursion systolique du plan de l'anneau tricuspide (TAPSE pour tricuspid annular plane systolic excursion) (p < 0,001) et le diamètre de la veine cave inférieure (VCI) (p < 0,001). D'autre part, les patients du groupe dont l'ICFER ne s'est pas résorbée présentaient des valeurs initiales plus élevées à l'indice de volume auriculaire gauche (IVAG) (p < 0,001). Lors d'une analyse multivariée, des valeurs de TAPSE plus élevées (rapport de cotes [RC] de 3,071; p = 0,008) et des valeurs plus faibles d'IVAG (RC de 2,034; p = 0,008) étaient deux variables échocardiographiques indépendantes associées avec la progression vers l'ICFEA. Après un suivi d'une durée moyenne de 32,5 ± 9,1 mois, le groupe présentant une ICFEA présentait un taux plus élevé de survie sans réhospitalisation due à une aggravation de l'IC et un taux plus faible de mortalités toutes causes confondues que le groupe dont l'ICFER ne s'était pas résorbée (p selon le test logarithmique par rangs < 0,001 et p = 0,005, respectivement). Conclusions: Une valeur de TAPSE élevée et un IVAG faible à l'évaluation initiale étaient associés à un passage de l'ICFER à l'ICFEA. La survie de patients présentant une ICFEA était supérieure à celle des patients présentant une ICFER non résorbée.
