Imaging predictors of adverse prognosis in Fabry disease cardiomyopathy: A systematic review and meta-analysis.

Cardiac involvement represents the main cause of death in patients with Fabry disease (FD). Echocardiography and cardiovascular magnetic resonance (CMR) have an established diagnostic role, but their prognostic value remains unresolved. This systematic review and meta-analysis sought to assess the prognostic implications of imaging parameters in FD. PubMed, ClinicalTrials.gov, Embase, Cochrane Library and Web of Science databases were searched for studies from inception through 1 May 2024. Studies including FD patients undergoing baseline imaging assessment and clinical follow-up were selected. Pre-defined study outcomes were a cardiovascular endpoint and a composite clinical endpoint. The study protocol was registered in PROSPERO (ID CRD42022342394). Fourteen studies, including 1713 FD patients (44.7% males), were selected. At pooled analysis, late gadolinium enhancement (hazard ratio [HR]: 4.45; 95% CI: 2.82-7.02), left atrium volume indexed (HR: 1.02 per mL/m2; 95% CI: 1.01-1.03), E/e' (HR: 1.14 per unit increase; 95% CI: 1.08-1.21), left ventricular (LV) mass indexed (HR: 1.01 per mg/m2; 95% CI: 1.00-1.02), maximum LV wall thickness (HR: 1.19 per mm, 95% CI: 1.04-1.36) and LV-global longitudinal strain (HR: 1.20 per unit increase; 95% CI: 1.16-1.25) were significantly associated with the cardiovascular endpoint, whereas T1-mapping and LV-ejection fraction were not. T1-mapping was associated with the composite endpoint (HR: 0.99 per msec increase; 95% CI: 0.98-1.00). Meta-regression analysis did not show any significant interaction between each of the potential effect modifiers. Several imaging parameters were significant predictors of adverse clinical outcomes in patients with FD. Late gadolinium enhancement showed the strongest association with adverse prognosis.

Transcatheter Edge-to-Edge Repair for Severe Isolated Tricuspid Regurgitation

Correction of tricuspid regurgitation using tricuspid transcatheter edge-to-edge repair (T-TEER) in addition to guideline-directed optimized medical therapy (OMT) may improve clinical outcomes. To evaluate the efficacy of T-TEER + OMT vs OMT alone in patients with severe, symptomatic tricuspid regurgitation. Investigator-initiated, prospective, randomized (1:1) trial evaluating T-TEER + OMT vs OMT alone in adult patients with severe, symptomatic tricuspid regurgitation. The trial was conducted at 24 centers in France and Belgium (March 2021 to March 2023; latest follow-up in April 2024). Patients were randomized to T-TEER + OMT or OMT alone. The primary outcome was a composite clinical end point at 1 year comprising change in New York Heart Association class, change in patient global assessment, or occurrence of major cardiovascular events. Tricuspid regurgitation severity was the first of 6 secondary outcomes analyzed in a hierarchical closed-testing procedure, including Kansas City Cardiomyopathy Questionnaire (KCCQ) score, patient global assessment, and a composite outcome of all-cause death, tricuspid valve surgery, KCCQ score improvement, or time to hospitalization for heart failure. Of 300 enrolled patients (mean age, 78 [SD, 6] years, 63.7% women), 152 were allocated to T-TEER + OMT and 148 to OMT alone. At 1 year, 109 patients (74.1%) in the T-TEER + OMT group had an improved composite score compared with 58 patients (40.6%) in the OMT-alone group. Massive or torrential tricuspid regurgitation was found in 6.8% of patients in the T-TEER + OMT group and in 53.5% of those in the OMT-alone group (P < .001). Mean overall KCCQ summary score at 1 year was 69.9 (SD, 25.5) for the T-TEER + OMT group and 55.4 (SD, 28.8) for the OMT-alone group (P < .001). The win ratio for the composite secondary outcome was 2.06 (95% CI, 1.38-3.08) (P < .001). T-TEER reduces tricuspid regurgitation severity and improves a composite score driven by improved patient-reported outcome measures in patients with severe, symptomatic tricuspid regurgitation.

Interleukin-1 Blockade in Patients With ST-Segment Elevation Myocardial Infarction Across the Spectrum of Coronary Artery Disease Complexity.

Patients with ST-segment elevation myocardial infarction (STEMI) and complex coronary artery disease (CAD) face a poor prognosis, including increased heart failure (HF) risk. Phase 2 clinical trials of anakinra have shown inhibition of the acute inflammatory response and prevention of HF after STEMI, but data on its effects based on CAD complexity are lacking. We performed a pooled secondary analysis of 139 patients with STEMI. The SYNTAX (Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery), SYNTAX II and Gensini scores were calculated, and patients were divided into two groups below and above the median. We evaluated the effect of anakinra on the area-under-the-curve of high-sensitivity C-reactive protein (hsCRP-AUC) at 14 days, and the composite endpoint of new-onset HF, HF hospitalization, or all-cause death at 1-year follow-up using Kaplan-Meier survival curves, Cox regression analysis for Hazard Ratios (HR), and tested interactions between subgroups. All three CAD complexity scores (SYNTAX, SYNTAX II and Gensini) were associated with an increased risk of adverse events (HR 1.02 to 1.06, all p-values ≤0.025). We found no statistically significant interactions between CAD extent, measured as single-vessel or multi-vessel CAD, SYNTAX score ≤9 or >9, SYNTAX II score ≤24 or >24, Gensini score ≤32 or >32, and treatment effect of anakinra on hsCRP-AUC or the composite clinical endpoint (all p-values for interaction >0.05). In conclusion, among patients with STEMI, IL-1 blockade with anakinra significantly attenuated the acute inflammatory response and reduced the risk of HF-related events regardless of the spectrum of CAD complexity.

Imaging predictors of adverse prognosis in fabry disease cardiomyopathy: a systematic review and meta-analysis

Abstract Background Cardiac involvement represents the main cause of death in patients with Fabry disease (FD). Echocardiography and Cardiac Magnetic Resonance (CMR) have an established diagnostic role, but their prognostic value remains unresolved. This systematic review and meta-analysis sought to assess the prognostic implications of imaging parameters in FD. Methods PubMed, ClinicalTrials.gov, Embase and Cochrane Library databases were searched for studies published from inception through to October 1, 2023. Full-length original papers including FD patients undergoing baseline imaging assessment and clinical follow-up were selected. Pre-defined study outcomes were a cardiovascular endpoint and a composite clinical endpoint. A meta-analysis of the studies investigating the effect of single imaging parameters on a pre-specified cardiovascular endpoint and a separate analysis on a pre-specified composite clinical endpoint were performed to obtain the pooled estimates for the association between the imaging parameters and the study outcome. The study protocol was registered in PROSPERO. Results Thirteen studies including 1,399 FD patients (44.8% males) were selected. At pooled analysis, late gadolinium enhancement (HR 4.39; 95% CI 2.5-7.71), left atrium volume indexed (HR 1.02 per ml/m2; 95% CI 1.01-1.04), E/e’ (HR 1.14 per unit increase; 95% CI 1.08-1.21), left ventricular (LV) mass indexed (HR 1.014 per mg/m2; 95% CI 1.006-1.023), maximum LV wall thickness (HR 1.19 per mm, 95% CI 1.04-1.36), LV-global longitudinal strain (HR 1.2 per unit increase; 95% CI 1.2-1.27), were significantly associated with the cardiovascular endpoint, whereas T1-mapping (p=0.115) and LV-ejection fraction (p=0.305) were not. T1-mapping was associated with the composite endpoint (HR 0.986 per msec increase; 95% CI 0.976-0.997). Meta-regression analysis did not show any significant interaction between each of the potential effect modifiers. Conclusion This meta-analysis demonstrates a robust prognostic value regarding several imaging parameters in FD, specifically indexes of LV mass and wall thickness, diastolic dysfunction, LV-GLS, and LGE presence. These findings support multimodality cardiovascular imaging, including CMR, in FD disease patients to predict long-term prognosis and call for longitudinal multicentre studies to develop multi-modality-imaging derived risk-score algorithms.

Transcatheter Aortic Valve Implantation by Valve Type in Women With Small Annuli

Historically, women with aortic stenosis have experienced worse outcomes and inadequate recognition compared to men, being both underdiagnosed and undertreated, while also facing underrepresentation in clinical trials. To determine whether women with small aortic annuli undergoing transcatheter aortic valve replacement have better clinical and hemodynamic outcomes with a self-expanding valve (SEV) or balloon-expandable valve (BEV). The Small Annuli Randomized to Evolut or SAPIEN Trial (SMART) was a large-scale randomized clinical trial focusing on patients with small aortic annuli undergoing transcatheter aortic valve replacement, randomized to receive SEVs or BEVs and included 716 patients treated at 83 centers in Canada, Europe, Israel, and the US from April 2021 to October 2022. This prespecified secondary analysis reports clinical and hemodynamic findings for all 621 women enrolled in SMART. Data for this report were analyzed from February to April 2024. Transcatheter aortic valve replacement with an SEV or a BEV. The composite coprimary clinical end point comprised death, disabling stroke, or heart failure-related rehospitalization. The coprimary valve function end point was the incidence of bioprosthetic valve dysfunction, both assessed through 12 months. Secondary end points included the incidence of moderate or severe prosthesis-patient mismatch. A total of 621 women (mean [SD] age, 80.2 [6.2] years; 312 randomized to the SEV group and 309 to the BEV group) were included in the present analysis. At 12 months, there were no significant differences in the coprimary clinical end point between the SEV and BEV groups (9.4% vs 11.8%, absolute risk difference -2.3%; 95% CI -7.2 to 2.5, P = .35). However, SEV implantation was associated with less bioprosthetic valve dysfunction (8.4% vs 41.8%; absolute risk difference, -33.4%; 95% CI, -40.4 to -26.4; P < .001). SEV implantation resulted in lower aortic valve gradients and larger effective orifice areas at 30 days and 12 months and less mild or greater aortic regurgitation at 12 months compared to BEV implantation. Prosthesis-patient mismatch was significantly lower with SEVs, regardless of the definition used and adjustment for body mass index. Use of SEVs was associated with better quality of life outcomes as assessed by the Valve Academic Research Consortium-3 ordinal quality of life measure. Among women with severe symptomatic aortic stenosis and small aortic annuli undergoing transcatheter aortic valve replacement, the use of SEVs, compared to BEVs, resulted in similar clinical outcomes and a markedly reduced incidence of bioprosthetic valve dysfunction through 12 months, including a lower risk of prosthesis-patient mismatch and better 12-month quality of life.

Validation of necrotising infection clinical composite endpoint in a retrospective cohort of patients with necrotising soft tissue infections.

Rapidly progressive necrotising soft tissue infections (NSTIs) are associated with high mortality and morbidity. Low incidence and disease heterogeneity contribute to low event rates and inadequately powered studies. The Necrotising Infections Clinical Composite Endpoint (NICCE) provides a binary outcome with which to assess interventions for NSTIs. Partly with a view towards studies of hyperbaric oxygen treatment in NSTIs we aimed to validate NICCE in a retrospective cohort of NSTI patients. Eligible patients were admitted between 2012 and 2021 to an adult major referral hospital in Victoria, Australia with surgically confirmed NSTI. The NICCE and its constituents were assessed in the whole cohort (n = 235). The cohort was divided into two groups using the modified sequential organ failure assessment (mSOFA) score, with an admission mSOFA score ≥ 3 defined as high acuity. Baseline characteristics of the whole (n = 235), the high (n = 188) and the low acuity cohorts (n = 47) were similar. Survival rates were high (91.1%). Patients with an admission mSOFA ≥ 3 were less likely to meet NICCE criteria for 'success' compared to the lower acuity cohort (34.1% and 64.7% respectively). Meeting NICCE criteria was significantly associated with lower resource utilisation, measured by intensive care unit days, ventilator days, and hospital length of stay for all patients and for those with high acuity on presentation. The NICCE provides greater discriminative ability than mortality alone. It accurately selects patients at high risk of adverse outcomes, thereby enhancing feasibility of trials. Adaptation of NICCE to include patient-centred outcomes could strengthen its clinical relevance.

Timing of oral anticoagulation in atrial fibrillation patients after acute ischaemic stroke and outcome after 3 months: results of the multicentre Berlin Atrial Fibrillation Registry

BackgroundOral anticoagulation (OAC) is key in stroke prevention in patients with atrial fibrillation (AF) but there is uncertainty regarding the optimal timing of OAC (re)initiation after stroke, as recent large...

Deceased donor urinary Dickkopf-3 associates with future allograft function following kidney transplantation

Predicting future kidney allograft function is challenging. Novel biomarkers, such as urinary Dickkopf-3 (uDKK3), may help guide donor selection and improve allograft outcomes. In this prospective multicenter pilot trial, we investigated whether donor uDKK3 reflects organ quality and is associated with future allograft function. We measured uDKK3/crea ratios (uDKK3/crea) from 95 deceased and 46 living kidney donors. Prenephrectomy uDKK3/crea levels were 100× higher in deceased than in living donors (9888 pg/mg vs 113 pg/mg; P < .001). Among deceased donor transplantations, recipients were stratified by their corresponding uDKK3/crea donor levels ranging below (group A, n = 68) or above (group B, n = 65) median. The primary end point of best estimated glomerular filtration rate (eGFR) within the first 3 months after kidney transplantation was superior in group A (56.3 mL/min/1.73 m2) than that in group B (44.2 mL/min/1.73 m2; P = .0139). Second, the composite clinical end point consisting of death, allograft failure or eGFR decline >50% occurred less frequent in group A. By mixed linear regression modeling, donor uDKK3/crea remained an independent predictor of eGFR after transplantation, with a slope of −4.282 mL/min/1.73 m2 per logarithmic increase in donor uDKK3/crea. In summary, uDKK3 may serve as a noninvasive, donor-dependent biomarker for assessing organ quality and future allograft function.

The impact of surgical timing on outcome in acute appendicitis in adults: a retrospective observational population-based cohort study.

Acute appendicitis is a global disease with high incidence. The main objective was to assess the association between time from admission to surgery (TAS) and surgery during emergency hours with operative outcome in light of conflicting evidence. This is a retrospective population-wide analysis of hospital billing data (2010-2021) of all adult patient records of surgically treated cases of acute appendicitis in Germany by TAS. The primary outcome was a composite clinical endpoint (CCE; prolonged length of stay, surgical site infection, interventional draining after surgery, revision surgery, ICU admission and/or in-hospital mortality). Cases of complicated appendicitis were identified using diagnosis (ICD-10) and procedural codes (resection beyond appendectomy). 855694 patient records were included, of which 27·6% (236,481) were complicated cases of acute appendicitis. 49·0% (418,821) were females and median age was 37 (interquartile range 22·5-51·5). Age, male sex, and comorbidity were associated with an increased proportion of CCE and in-hospital mortality. TAS was associated with a clinically relevant increase of CCE after 12h in complicated appendicitis [Odd's ratio (OR), 1·19, 95% CI: 1·14-1·21] and after 24h in uncomplicated appendicitis (OR 1·10, 95% CI: 1·02-1·19). Beyond the primary endpoint, the proportion of complicated appendicitis increased after TAS of 72h. Surgery during emergency hours (6 pm-6.59 am) was associated with an increase of CCE and mortality (OR between 1·14 and 1·49). Age, female sex, night-time admission, weekend admission, a known previous surgery, obesity, and therapeutic anticoagulation were associated with delayed performance of surgery. This work found an increase of a CCE after TAS of 12h for complicated appendicitis and an increase of the CCE after TAS of 24h for uncomplicated appendicitis with a stable proportion of complicated appendicitis in these time windows. Both CCE and mortality were increased if appendectomy was performed during emergency hours.

Thyroid dysfunction in nonvalvular atrial fibrillation and clinical outcomes.

Thyroid dysfunction's effects on those who have been diagnosed with atrial fibrillation have not been well investigated. We looked at how thyroid function among patients with pre-existing atrial fibrillation related to thromboembolic risk and clinical outcomes. We gathered the medical information of patients diagnosed with nonvalvular atrial fibrillation (NVAF) between 2016 and 2020 at Dongguan People's Hospital. We then assessed the correlation between thyroid dysfunction and thrombotic risk (CHA2DS2-VASc) as well as the occurrence of clinical composite endpoint (all-cause death, heart failure, systemic embolism and hemorrhage events). Of 1329 patients were admitted, 82.6% were euthyroid, 7.4% had subclinical hyperthyroidism, 4.2% had subclinical hypothyroidism, and 6.7% had low triiodothyronine (T3) syndrome. Lower levels of total triiodothyronine (TT3) were linked to an increased risk of thromboembolism (P < 0.005). During a median follow-up period of 1.84 years, there were 608 clinical composite endpoint occurrences. In the adjusted model, Low T3 syndrome was linked to a higher risk of the clinical composite endpoint (HR, 1.68; 95% CI, 1.20-2.37; P < 0.05) in comparison to euthyroidism. Specifically, low T3 syndrome was linked to a higher risk of heart failure (HR, 1.52; 95%CI, 1.01-2.30; P < 0.05) and all-cause death (HR, 3.34; 95% CI, 1.76-6.36; P < 0.001). Low T3 syndrome are linked to an increased risk of heart failure and all-cause death in individuals with NVAF. And Patients with NVAF and low TT3 levels have a higher risk of thromboembolism.

Physical activity decreases in patients on the liver transplant waiting list and influences postoperative outcome-a prospective cohort study.

Physical deconditioning affects patients suffering from end-stage liver disease (ESLD). Liver transplantation (LT) is the only curative option for ESLD. Growing evidence suggests that pre-habilitation is beneficial in reducing post-surgical morbidity and mortality. We investigated physical activity (PA) in patients awaiting LT in a country with long waiting times. Prospective, single center, longitudinal study in Bern, Switzerland between June 2019 and February 2020 (halted due to SARS-CoV-2 pandemic), with follow-up data up to six months post-transplant. Patients were instructed to use a wrist tracker (FitBit) to monitor PA, which was assessed using mixed-effects generalized linear models. The study was approved by the local ethics committee (BASEC ID 2019-00606). Thirty-five patients were included [71% male, median 59 years, body mass index (BMI) 28 kg/m2, lab Model End-Stage Liver Disease (MELD) 11], 17 (49%) pre-frail and 5 (14%) frail according to the Liver Frailty Index (LFI). Twenty-eight patients underwent transplantation with 0 ninety-day mortality and 15 (53.6%) composite adverse clinical outcome. Median daily steps were 4,661 [interquartile range (IQR), 1,685-8,609] and weekly moderate PA (MPA) was 41 min (IQR, 0-127 min). Longitudinal analysis showed that female patients and patients on nutritional support had an increase in MPA between weeks 20 and 40. A significant decrease was seen in MPA after week 40, whilst no significant association was seen with age, Child-Pugh Score, LFI or quality of life at time of inclusion. MPA was significantly associated with the occurrence of the composite clinical endpoint after week 30 of waiting time (odds ratio 0.882, P=0.026). World Health Organization (WHO)-recommended MPA was significantly associated with less adverse composite clinical outcomes (P<0.001). In patients listed for LT, MPA decreased over time, showing a significant association with adverse outcome, specifically after week 30 on the waiting list. Our data support the implementation of routine pre-habilitation in patients awaiting LT.

Computed tomography anatomic predictors of outcomes in patients undergoing tricuspid transcatheter edge-to-edge repair

AimTo identify anatomical computed tomography (CT) predictors of procedural and clinical outcomes in patients undergoing tricuspid transcatheter edge-to-edge repair (T-TEER). Methods and resultsConsecutive patients undergoing T-TEER between March 2018 to December 2022 who had cardiac CT prior to the procedure were included. CT scans were automatically analyzed using a dedicated software that employs deep learning techniques to provide precise anatomical measurements and volumetric calculations. Technical success was defined as successful placement of at least one implant in the planned anatomic location without single leaflet device attachment. Procedural success was defined as tricuspid regurgitation reduction to moderate or less. Procedural complexity was assessed by measuring the fluoroscopy time. The clinical endpoint was a composite of death, heart failure hospitalization, or tricuspid re-intervention throughout two years. A total of 33 patients (63.6% male) were included. Procedural success was achieved in 22 patients (66.7%). Shorter end-systolic (ES) height between the inferior vena cava (IVC) and tricuspid annulus (TA) (r ​= ​- 0.398, p ​= ​0.044) and longer ES RV length (r ​= ​0.551, p ​= ​0.006) correlated with higher procedural complexity. ES RV length was independently associated with lower technical(adjusted Odds ratio [OR] 0.812 [95% CI 0.665–0.991], p ​= ​0.040) and procedural success (adjusted OR 0.766, CI [0.591–0.992], p ​= ​0.043). Patients with ES right ventricular (RV) length of >77.4 ​mm had a four-fold increased risk of experiencing the composite clinical endpoint compared to patients with ES RV length ≤77.4 ​mm (HR ​= ​3.964 [95% CI, 1.018–15.434]; p ​= ​0,034]). ConclusionCT-derived RV length and IVC-to-TA height may be helpful to identify patients at increased risk for procedural complexity and adverse outcomes when undergoing T-TEER. CT provides valuable information for preprocedural decision-making and device selection.

Gender Differences Among Very Young Patients With Acute Coronary Syndrome: Long-Term Follow-Up of the STAMINA Study

The rate of hospitalization for acute coronary syndrome (ACS) among young patients is increasing. Healthcare disparities remain unsolved among female patients. We explored gender differences regarding risk factors, clinical presentation, in-hospital treatment, and long-term outcomes among ACS patients. A total of 445 patients with very early ACS (men ≤ 35 years and women ≤ 40 years of age) were followed for a median of 5 years. Primary clinical endpoint was the composite of cardiac death, non-fatal myocardial infarction, stroke, and coronary revascularization. Women accounted for 16% of cases. Smoking was the most prevalent risk factor, 56% and 60% of the females and males, respectively, continued to smoke after ACS. Chest pain was typical in 85% and 83% of the female and male patients, respectively. In-hospital treatment (pharmacological and reperfusion) as well as the composite clinical endpoint during follow-up did not differ between female and male patients. Lipid-lowering therapy was suboptimal in both genders, and persistence of smoking was the sole predictor for the composite clinical endpoint (hazard ratio: 2.30 [95% CI: 1.26–4.20]; P = .007). In conclusion, in-hospital treatment was similar between male and female patients. However, the majority of them continued smoking, and this was an independent predictor for future adverse outcomes.

Early Discharge to Clinic-Based Therapy of Patients Presenting With Decompensated Heart Failure (EDICT-HF): Study Protocol for a Multi-Centre Randomised Controlled Trial

Acute decompensated heart failure involves a high rate of mortality and complications. Management typically involves a multi-day hospital admission. However, patients often lose part of their function with each successive admission, and are at a high risk for hospital-associated complications such as nosocomial infection. This study aims to determine the safety and efficacy of the management of patients presenting with acute decompensated heart failure to clinic-based therapy vs usual inpatient care using a reproducible management pathway. An investigator-initiated, prospective, non-inferiority, 1:1 randomised-controlled trial, stratified by left ventricular ejection fraction including 460 patients with a minimum follow-up of 7 days. This is a multi-centre study to be performed in centres across Victoria, Australia. Participants will be patients with either heart failure with reduced ejection fraction (HFrEF) or heart failure with preserved ejection fraction (HFpEF), admitted for acute decompensation of heart failure. Early discharge to an outpatient-based Heart Failure Rapid Access Clinical Review (RACER) in addition to frequent medical/nursing at-home review for patients admitted with decompensated heart failure. The primary endpoint will be a non-inferiority assessment of re-hospitalisation at 30 days. Secondary outcomes include superiority assessment of hospitalisation at 30 days, a composite clinical endpoint of major adverse cardiac and cerebrovascular event (MACCE), hospital re-admission or mortality at 3 months, achievement of guideline-directed medical therapy, patient assessment of symptoms (visual-analogue scale quantified as area under curve and Kansas City Cardiomyopathy Questionnaire-12 [KCCQ-12]), attendance at 3-month outpatient follow-up, number of bed stays/clinics attended, proportion of patients free from congestion, change in serum creatinine level, treatment for electrolyte disturbances, time to transition from intravenous to oral diuretics, and health economics analysis (cost-benefit analysis, cost-utility analysis, incremental cost-effectiveness ratio). The Early Discharge to Clinic-Based Therapy of Patients Presenting with Decompensated Heart Failure (EDICT-HF) trial will help determine whether earlier discharge to out-of-hospital care is non-inferior to the usual practice of inpatient care, in patients with heart failure admitted to hospital for acute decompensation, as an alternative model of care.

Coronary no-reflow and adverse events in patients with acute myocardial infarction after percutaneous coronary intervention with current drug-eluting stents and third-generation P2Y12 inhibitors.

The frequency and prognostic value of coronary no-reflow (CNR) was investigated in studies that have used an outdated reperfusion therapy in terms of stent technology and antithrombotic drugs. We assessed the association of CNR with adverse outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) and newer antithrombotic drugs, ticagrelor or prasugrel. This study included 3100 patients with AMI who underwent PCI with current DES and third-generation P2Y12 inhibitors. CNR was defined as Thrombolysis in Myocardial Infarction (TIMI) blood flow grade ≤ 2 at the end of PCI. The primary end point was 1-year incidence of net adverse clinical and cerebral events-a composite end point of death of any cause, myocardial infarction, stroke or major bleeding. CNR was diagnosed in 130 patients (4.2%). The primary end point occurred in 28 patients in the CNR group and 354 patients in the reflow group (cumulative incidence 23.2% and 12.8%; adjusted hazard ratio = 1.53, 95% confidence interval 1.01-2.33; P = 0.049). The 1-year incidences of death or myocardial infarction (14.6% vs. 7.6%; P = 0.003), myocardial infarction (8.8% vs. 3.9%; P = 0.007) and major bleeding (10.9% vs. 5.6%; P = 0.008) were significantly higher in patients with CNR than patients with reflow. The risk of adverse events in patients with CNR was highest within the first 30days after PCI. In patients with AMI undergoing PCI with current DES and third generation P2Y12 receptor inhibitors, CNR was associated with a higher risk of adverse outcomes at 1year.

Frequency, predictors and clinical outcomes of AMI patients with triple regression of coronary atherosclerosis: A sub-analysis of the PACMAN AMI trial

Abstract Background Recent studies have shown that coronary artery disease regression is not limited to atheroma reduction but also includes plaque stabilization in patients treated with high-intensity lipid-lowering therapy. The frequency and characteristics of patients who simultaneously show atheroma volume reduction and plaque stabilization defined as reduction in plaque lipid content and increase in fibrous cap thickness (i.e., triple regression) are unknown. Purpose This study sought to determine the percentage and determinants of both plaque volume reduction and plaque stabilization in patients with acute myocardial infarction (MI) and treated wiTh alirocumab or placebo added to high-intensity statin therapy. Methods The PACMAN-AMI trial employed serial intravascular ultrasound, near-infrared spectroscopy and optical coherence tomography to compare the effects of alirocumab vs. placebo (1:1) in 265 patients (537 non–infarct-related coronary arteries) receiving high-intensity statin therapy. Triple regression was defined by the combined presence of reduction in percent atheroma volume (PAV), reduction in maximum lipid core burden index (maxLCBI4mm) and increase in minimal fibrous cap thickness (FCT). Clinical outcomes of patients with or without triple regression were assessed at one year follow-up. Results Overall, 199 (75.1%) patients showed PAV reduction, 180 (67.7%) maxLCBI4mm reduction and 172 (77.6%) minimal FCT increase, with a total of 84 (31.7%) patients having triple regression (40.8% in the alirocumab group vs. 23.0% in the placebo group, p=0.002). The percentage of patients with triple regression was similar among the groups with PAV reduction, maxLCBI4mm reduction or minimal FCT thickening (42%, 51% or 49%, respectively, p=0.30). Similar baseline clinical features and a higher reduction in low-density lipoprotein cholesterol (LDL-C, -27.1 [37.7 to -16.6] mg/dl, p&amp;lt;0.001) and apolipoprotein B levels (-18.5 [-26.0 to -11.0] p&amp;lt;0.001) were observed patienst with vs. without triple regression. A higher reduction in PAV (-1.54 [-2.14 to -0.95] %, p&amp;lt;0.001), maxLCBI4mm (-111.24 [-140.46 to -82.02], p&amp;lt;0.001) and a higher increase in minimal FCT (56.39 [38.67 to 74.11] µm, p&amp;lt;0.001) were found in patients with triple regression. At multivariable analysis, factors independently associated with triple regression included higher baseline maxLCBI4mm (1.03, 1.01 to 1.06, p=0.013) and alirocumab treatment (2.83, 1.57 to 5.16, p=0.001). The composite clinical endpoint of death, MI and ischemia-driven revascularization occurred less frequently in patients with versus without triple regression (8.3% vs 18.2%, p=0.042). Conclusions Triple regression occurred among one third of acute AMI patients receiving high-intensity lipid lowering therapy. Alirocumab treatment and higher baseline lipid accumulation were independent predictors of triple regression. Triple regression was associated with a reduced rate of adverse cardiovascular events.

Concomitant Coronary Atheroma Regression and Stabilization in Response to Lipid-Lowering Therapy

BackgroundThe frequency, characteristics, and outcomes of patients treated with high-intensity lipid-lowering therapy and showing concomitant atheroma volume reduction, lipid content reduction, and increase in fibrous cap thickness (ie, triple regression) are unknown. ObjectivesThis study was designed to investigate rates, determinants, and prognostic implications of triple regression in patients presenting with acute myocardial infarction and treated with high-intensity lipid-lowering therapy. MethodsThe PACMAN-AMI (Effects of the PCSK9 Antibody Alirocumab on Coronary Atherosclerosis in Patients with Acute Myocardial Infarction) trial used serial intravascular ultrasound, near-infrared spectroscopy, and optical coherence tomography to compare the effects of alirocumab vs placebo in patients receiving high-intensity statin therapy. Triple regression was defined by the combined presence of percentage of atheroma volume reduction, maximum lipid core burden index within 4 mm reduction, and minimal fibrous cap thickness increase. Clinical outcomes at 1-year follow-up were assessed. ResultsOverall, 84 patients (31.7%) showed triple regression (40.8% in the alirocumab group vs 23.0% in the placebo group; P = 0.002). On-treatment low-density lipoprotein cholesterol levels were lower in patients with vs without triple regression (between-group difference: −27.1 mg/dL; 95% CI: −37.7 to −16.6 mg/dL; P < 0.001). Triple regression was independently predicted by alirocumab treatment (OR: 2.83; 95% CI: 1.57-5.16; P = 0.001) and a higher baseline maximum lipid core burden index within 4 mm (OR: 1.03; 95% CI: 1.01-1.06; P = 0.013). The composite clinical endpoint of death, myocardial infarction, and ischemia-driven revascularization occurred less frequently in patients with vs without triple regression (8.3% vs 18.2%; P = 0.04). ConclusionsTriple regression occurred in one-third of patients with acute myocardial infarction who were receiving high-intensity lipid-lowering therapy and was associated with alirocumab treatment, higher baseline lipid content, and reduced cardiovascular events.

Pulmonary embolism in COVID-19 pneumonia patients admitted to temporary hospital - The follow-up study

PurposeCoronavirus disease 2019 (COVID-19) is linked with major coagulation disorders, especially higher risk of developing pulmonary embolism (PE). Our study summarizes COVID-19 patients’ management with concomitant PE during the first weeks of pandemic and underlines the importance of D-dimer concentration assessment at admission in terms of prognosis. Material and methodsStudy group consisted of 107 outpatients (mean age 68.91 ​± ​12.83 years) admitted to the Temporary COVID-19 Hospital in Bialystok, Poland with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and suspicion of PE based on elevated D-dimer concentration (>500 ​μg/l) and/or low saturation rate (<90%). The clinical follow-up lasted 6 months. Death or re-hospitalization were used as composite clinical endpoint (CEP). ResultsCumulative incidence of PE was 62.3% (73/107 patients). Most of the patients were in the intermediate PE risk group according to the pulmonary embolism severity index (PESI) score. The mean total computed tomography (CT) lung involvement of COVID-19 findings was 48.42 ​± ​27.71%. Neither D-dimers nor NT-proBNP concentrations correlated significantly with the percentage of lung abnormalities in CT. Patients with baseline D-dimer concentration higher than 1429 ​μg/l had worse prognosis in 6-months observation, log-rank test, p ​= ​0.009. ConclusionsOngoing SARS-CoV-2 infection along with massive involvement of lung tissue and concomitant thrombi in pulmonary arteries are challenging for physicians. It seems that simple D-dimer concentration assessment at admission may be a helpful tool not only to predict PE but also to estimate the long-term prognosis.

Effectiveness of adding a defibrillator with cardiac resynchronization therapy in heart failure according to the modified Model for End-stage Liver Disease-Albumin score.

Current guidelines lack clear recommendations between the implantation of cardiac resynchronization therapy (CRT) with defibrillator (CRT-D) and CRT with pacemaker (CRT-P). We hypothesized that modified model for end-stage liver disease score including albumin (MELD-Albumin score), could be used to select patients who may not benefit from CRT-D. We consecutively included patients with CRT-P or CRT-D implantation between 2010 and 2022. The primary endpoint was the composite of all-cause mortality or worsening heart failure. We performed multivariable-adjusted Cox proportional hazard regression. We assessed the interaction between the MELD-Albumin score and the effect of adding a defibrillator with CRT.A total of 752 patients were included in this study, with 291 implanted CRT-P. During a median follow-up of 880 days, 205 patients reached the primary endpoint. MELD-Albumin score was significantly associated with the primary endpoint in the CRT-D group [HR 1.16 (1.09-1.24); P < 0.001] but not in the CRT-P group [HR 1.03 (0.95-1.12); P = 0.49]. There was a significant interaction between the MELD-Albumin score and the effect of CRTD (P = 0.013). The optimal cut-off value of the MELD-Albumin score was 12. For patients with MELD-Albumin ≥ 12, CRT-D was associated with a higher occurrence of the primary endpoint [HR 1.99 (1.10-3.58); P = 0.02], whereas not in patients with MELD-Albumin < 12 [HR 1.19 (0.83-1.70); P = 0.35). Our findings suggest that CRT-D is associated with an excess risk of composite clinical endpoints in HF patients with higher MELD-Albumin score.

Outcome of percutaneous coronary intervention using ultrathin-strut biodegradable polymer sirolimus-eluting versus thin-strut durable polymer zotarolimus-eluting stents in patients with comorbid peripheral arterial disease: a post-hoc analysis from two randomized trials.

In patients with peripheral arterial disease (PADs), who underwent percutaneous coronary intervention (PCI), little is known about the potential impact of using different new-generation drug-eluting stents (DES) on outcome. In PCI all-comers, the results of most between-stent comparisons-stratified by strut thickness-suggested some advantage of coronary stents with ultrathin-struts. The current post-hoc analysis aimed to assess outcomes of PCI with ultrathin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) vs. thin-strut durable polymer zotarolimus-eluting stents (DP-ZES) in patients with PADs. We pooled 3-year patient-level data from two large-scale randomized all-comer trials to compare Orsiro ultrathin-strut BP-SES vs. Resolute-type thin-strut DP-ZES in trial participants with concomitant PADs. BIO-RESORT (December 2012 to August 2015) and BIONYX (October 2015 to December 2016) included all-comer patients who were aged 18 years or older, capable of providing informed consent, and required a PCI. The trials had web-based randomization, with block sizes of 4 and 8, performed in a 1:1:1 or 1:1 fashion. Assessors, research staff, and patients were blinded to the type of stent used. We assessed the composite main clinical endpoint target vessel failure [TVF: cardiac death, target vessel related myocardial infarction (MI), or clinically indicated target vessel revascularization (TVR)], its components, and stent thrombosis. Of 4,830 trial participants, 360 had PADs: 177 (49.2%) were treated with BP-SES and 183 (50.8%) with DP-ZES. Baseline characteristics were similar. For BP-SES, the 3-year TVF rate was 11.0% and for DP-ZES 17.9% [hazard ratio (HR): 0.59, 95% CI: 0.33-1.04; P=0.07]. For BP-SES, the TVR rate was lower than for DP-ZES (4.1% vs. 11.0%; HR: 0.36, 95% CI: 0.15-0.86; P=0.016), but this did not translate into between-group differences in cardiac death or MI. In small vessels (<2.75 mm), the TVR rate was also lower in BP-SES (5.6% vs. 13.9%; HR: 0.32, 95% CI: 0.11-0.91; P=0.024). Definite-or-probable stent thrombosis rates were 1.2% and 2.3% (P=0.43). In PCI patients with PADs, the 3-year TVF incidence was numerically lower in the ultrathin-strut BP-SES vs. the thin-strut DP-ZES group. Furthermore, TVR risk was significantly lower in ultrathin-strut BP-SES, mainly driven by a lower TVR rate in small vessels.
