INTRODUCTION: The treatment of patients with cardiogenic shock (CS) encompasses several health technologies including Impella pumps and venoarterial extracorporeal membrane oxygenation (VA-ECMO). However, while they are widely used in clinical practice, information on resource use and quality of life (QoL) associated with these devices is scarce. The aim of this study is, therefore, to collect and comparatively assess clinical and socioeconomic data of Impella versus VA-ECMO for the treatment of patients with severe CS, to ultimately conduct both a cost-effectiveness (CEA) and budget impact (BIA) analyses. METHODS AND ANALYSIS: This is a prospective plus retrospective, multicentre study conducted under the scientific coordination of the Center for Research on Health and Social Care Management of SDA Bocconi School of Management and clinical coordination of Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) San Raffaele Scientific Institute in Milan. The Impella Network stemmed for the purposes of this study and comprises 17 Italian clinical centres from Northern to Southern Regions in Italy. The Italian network qualifies as a subgroup of the international Impella Cardiac Surgery Registry. Patients with CS treated with Impella pumps (CP, 5.0 or 5.5) will be prospectively recruited, and information on clinical outcomes, resource use and QoL collected. Economic data will be retrospectively matched with data from comparable patients treated with VA-ECMO. Both CEA and BIA will be conducted adopting the societal perspective in Italy. This study will contribute to generate new socioeconomic evidence to inform future coverage decisions. ETHICS AND DISSEMINATION: As of May 2024, most of the clinical centres submitted the documentation to their ethical committee (N=13; 76%), six centres received ethical approval and two centres started to enrol patients. Study results will be published in peer-reviewed publications and disseminated through conference presentations.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve (BAV) stenosis is technically challenging and is burdened by an increased risk of paravalvular regurgitation (PVR). OBJECTIVES: The aim of this study was to identify the incidence, predictors, and clinical outcomes of PVR after TAVR in Sievers type 1 BAV stenosis. METHODS: Consecutive patients with Sievers type 1 BAV stenosis undergoing TAVR with current-generation transcatheter heart valves (THVs) in 24 international centers were enrolled. PVR was graded as none/trace, mild, moderate, and severe according to echocardiographic criteria. The endpoint of major adverse events (MAEs), defined as a composite of all-cause death, stroke, or hospitalization for heart failure, was assessed at the last available follow-up. RESULTS: A total of 946 patients were enrolled. PVR occurred in 423 patients (44.7%)-mild, moderate, and severe in 387 (40.9%), 32 (3.4%), and 4 (0.4%) patients, respectively. Independent predictors of moderate or severe PVR were a larger virtual raphe ring perimeter (adjusted OR: 1.07; 95% CI: 1.02-1.13), severe annular or left ventricular outflow tract calcification (adjusted OR: 5.21; 95% CI: 1.45-18.77), a self-expanding valve (adjusted OR: 9.01; 95% CI: 2.09-38.86), and intentional supra-annular THV positioning (adjusted OR: 3.31; 95% CI: 1.04-10.54). At a median follow-up of 1.3 years (Q1-Q3: 0.5-2.4 years), moderate or severe PVR was associated with an increased risk of MAEs (adjusted HR: 2.52; 95% CI: 1.24-5.09). CONCLUSIONS: After TAVR with current-generation THVs in Sievers type 1 BAV stenosis, moderate or severe PVR occurred in about 4% of cases and was associated with an increased risk of MAEs during follow-up.

BACKGROUND AND AIMS: Conflicting data are available regarding the association between periprocedural myocardial infarction (PMI) and mortality following percutaneous coronary intervention. The purpose of this study was to evaluate the incidence and prognostic implication of PMI according to the Universal Definition of Myocardial Infarction (UDMI), the Academic Research Consortium (ARC)-2 definition, and the Society for Cardiovascular Angiography and Interventions (SCAI) definition. METHODS: Studies reporting adjusted effect estimates were systematically searched. The primary outcome was all-cause death, while cardiac death was included as a secondary outcome. Studies defining PMI according to biomarker elevation without further evidence of myocardial ischaemia ('ancillary criteria') were included and reported as 'definition-like'. Data were pooled in a random-effect model. RESULTS: A total of 19 studies and 109 568 patients were included. The incidence of PMI was progressively lower across the UDMI, ARC-2, and SCAI definitions. All PMI definitions were independently associated with all-cause mortality [UDMI: hazard ratio (HR) 1.61, 95% confidence interval (CI) 1.32-1.97; I2 34%; ARC-2: HR 2.07, 95% CI 1.40-3.08, I2 0%; SCAI: HR 3.24, 95% CI 2.36-4.44, I2 78%]. Including ancillary criteria in the PMI definitions were associated with an increased prognostic performance in the UDMI but not in the SCAI definition. Data were consistent after evaluation of major sources of heterogeneity. CONCLUSIONS: All currently available international definitions of PMI are associated with an increased risk of all-cause death after percutaneous coronary intervention. The magnitude of this latter association varies according to the sensitivity and prognostic relevance of each definition.
RESUMEN
BACKGROUND: Previous studies have investigated a 1 to 6-month short dual antiplatelet therapy (S-DAPT) after percutaneous coronary intervention (PCI) with modern drug eluting-stents to reduce bleeding events. OBJECTIVES: To investigate cardiovascular outcomes in patients at high bleeding risk (HBR) according to the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria after PCI with the Synergy bioresorbable-polymer everolimus-eluting stents (EES). METHODS: We applied ARC-HBR criteria in the population of the prospective, single-arm, multicenter POEM (Performance of Bioresorbable Polymer-Coated Everolimus-Eluting Synergy Stent in Patients at HBR Undergoing Percutaneous Coronary Revascularization Followed by 1-Month Dual Antiplatelet Therapy) trial. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 12 months. RESULTS: The original POEM cohort included 356 patients (80.4 %) fulfilling ARC-HBR criteria. Oral anticoagulant (OAC) usage and age ≥75 years were the most frequent major and minor ARC-HBR criteria, respectively. The ARC-HBR group was mainly represented by men (71.1 %), with 74.4 ± 9.3 years and a high burden of cardiovascular risk factors. DAPT was prescribed in 79.3 %, and single antiplatelet (SAPT) with OAC in 18.7 %. 12-month follow-up was completed in 96.2 %. The primary endpoint occurred in 5.2 % (95 % CI 3.29-8.10) of patients, whereas bleeding Academic Research Consortium type 3-5 occurred in 2.7 % (95 % CI, 1.39 %-5.05 %). CONCLUSION: Previous results of the POEM trial showed positive outcomes regarding ischemic and bleeding events with an S-DAPT regimen after Synergy EES. These results are also confirmed in sub-group analysis when ARC-HBR criteria are applied.
RESUMEN
BACKGROUND: Percutaneous coronary intervention (PCI) for bifurcation lesions still represents a clinical challenge. The Bioss Lim C is a dedicated device for bifurcation lesions, features a tapered shape and large cells, and thus appears as a promising adjunct to the current interventional cardiologists' armamentarium. We aimed at conducting a prospective multicenter study focusing on early and long-term results after Bioss Lim C implantation for true coronary bifurcation lesions. METHODS: Patients with true bifurcation lesions in whom Bioss Lim C implantation was attempted were enrolled in four Italian centers. An explicit bifurcation management approach was recommended, leaving however the choice between one- vs. two-stent strategies at operator's discretion. Acute and long-term results were systematically appraised, focusing on an acute composite of complex side branch (SB) rewiring, SB pinching, or SB occlusion (primary efficacy endpoint), as well as major adverse events (MACE, i.e. death, myocardial infarction [MI], or target vessel revascularization [TVR]), individual components of MACE, and stent thrombosis. RESULTS: A total of 207 patients were included, with age of 67.3±10.8 years, and 40 (19.3%) women. The target lesion was located in the left main in 48 (23.2%) patients, whereas proximal reference vessel diameter was 3.69±0.48 mm, and lesion length 20.3±3.4 mm. According to the Medina classification, most patients (60 [30.9%]) had 1-1-1 lesions. Drug-eluting stent implantation in the SB was carried out in 19 (9.3%) subjects, and kissing balloon inflation was used in 67 (32.5%). The primary efficacy endpoint occurred in 27 (13.0%), with side branch (SB) occlusion in two (1.0%), SB pinching in 23 (11.1%), and complex SB rewiring in six (2.9%), and was most frequent in patients with lower body mass index or dyslipidemia. After 24.1±19.5 months, MACE were adjudicated in 23 (11.1%) subjects, with death in 10 (4.8%), MI in six (2.9%), and TVR in seven (3.4%), as well as stent thrombosis in one (0.5%). CONCLUSIONS: This study supports a wider adoption of the Bioss Lim C dedicated bifurcation device, thanks to the favorable acute results as well as long-term clinical outcomes, as well as its versatility for the stenting strategy provisionally or eventually adopted by operators.

BACKGROUND: The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI. METHODS: In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization. RESULTS: Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446). CONCLUSIONS: Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.

BACKGROUND: Acute kidney injury (AKI) is common in patients with acute coronary syndromes (ACS) treated by percutaneous coronary intervention. OBJECTIVES: Contrast media (CM) volume minimization has been advocated for prevention of AKI. The DyeVert CM diversion system (Osprey Medical, Inc) is designed to reduce CM volume during coronary procedures. METHODS: In this randomized, single-blind, investigator-driven clinical trial conducted in 4 Italian centers from February 4, 2020 to September 13, 2022, 550 participants with ACS were randomly assigned in a 1:1 ratio to the following: 1) the contrast volume reduction (CVR) group (n = 276), in which CM injection was handled by the CM diversion system; and 2) the control group (n = 274), in which a conventional manual or automatic injection syringe was used. The primary endpoint was the rate of AKI, defined as a serum creatinine (sCr) increase ≥0.3 mg/dL within 48 hours after CM exposure. RESULTS: There were 412 of 550 (74.5%) participants with ST-segment elevation myocardial infarction (211 of 276 [76.4%] in the CVR group and 201 of 274 [73.3%] in the control group). The CM volume was lower in the CVR group (95 ± 30 mL vs 160 ± 23 mL; P < 0.001). Seven participants (1 in the CVR group and 6 in the control group) did not have postprocedural sCr values. AKI occurred in 44 of 275 (16%) participants in the CVR group and in 65 of 268 (24.3%) participants in the control group (relative risk: 0.66; 95% CI: 0.47-0.93; P = 0.018). CONCLUSIONS: CM volume reduction obtained using the CM diversion system is effective for prevention of AKI in patients with ACS undergoing invasive procedures.

BACKGROUND: To assess the reproducibility of coronary tissue characterization by an Artificial Intelligence Optical Coherence Tomography software (OctPlus, Shanghai Pulse Medical Imaging Technology Inc.). METHODS: 74 patients presenting with multivessel ST-segment elevation myocardial infarction (STEMI) underwent optical coherence tomography (OCT) of the infarct-related artery at the end of primary percutaneous coronary intervention (PPCI) and during staged PCI (SPCI) within 7 days thereafter in the MATRIX (Minimizing Adverse Hemorrhagic Events by Transradial Access Site and angioX) Treatment-Duration study (ClinicalTrials.gov, NCT01433627). OCT films were run through the OctPlus software. The same region of interest between either side of the stent and the first branch was identified on OCT films for each patient at PPCI and SPCI, thus generating 94 pairs of segments. 42 pairs of segments were re-analyzed for intra-software difference. Five plaque characteristics including cholesterol crystal, fibrous tissue, calcium, lipid, and macrophage content were analyzed for various parameters (span angle, thickness, and area). RESULTS: There was no statistically significant inter-catheter (between PPCI and SPCI) or intra-software difference in the mean values of all the parameters. Inter-catheter correlation for area was best seen for calcification [intraclass correlation coefficient (ICC) 0.86], followed by fibrous tissue (ICC 0.87), lipid (ICC 0.62), and macrophage (ICC 0.43). Some of the inter-catheter relative differences for area measurements were large: calcification 9.75 %; cholesterol crystal 74.10 %; fibrous tissue 5.90 %; lipid 4.66 %; and macrophage 1.23 %. By the intra-software measurements, there was an excellent correlation (ICC > 0.9) for all tissue types. The relative differences for area measurements were: calcification 0.64 %; cholesterol crystal 5.34 %; fibrous tissue 0.19 %; lipid 1.07 %; and macrophage 0.60 %. Features of vulnerable plaque, minimum fibrous cap thickness and lipid area showed acceptable reproducibility. CONCLUSION: The present study demonstrates an overall good reproducibility of tissue characterization by the Artificial Intelligence Optical Coherence Tomography software. In future longitudinal studies, investigators may use discretion in selecting the imaging endpoints and sample size, accounting for the observed relative differences in this study.

OBJECTIVES: Several volume expansion protocols have been proposed to prevent contrast-associated acute kidney injury (CA-AKI). The aim of our study was to seek the ideal intravenous volume expansion to prevent CA-AKI in patients with chronic kidney disease (CKD) undergoing invasive cardiovascular procedures. METHODS: We analyzed 1927 CKD patients enrolled in 6 studies that took place from September 15, 2000 to June 6, 2019. Four volume expansion regiments were included: (1) conventional group (n=625); (2) bicarbonate group (n=255); (3) left ventricular end-diastolic pressure-guided group (n=355); and (4) urine flow rate-guided group (n=500). RESULTS: CA-AKI (serum creatinine increase ≥0.3 mg/dL at 48 hours) occurred in 224 (11%) patients. In patients with CA-AKI, volume expansion was lower (2090 ± 1382 mL vs 2551 ± 1716 mL; P less than .001) and acute pulmonary edema occurred more often (3.5% vs 0.29%; P less than .001). By ROC curve analysis, an absolute volume expansion greater than or equal to 1430 mL (AUC = 0.70) and a volume expansion to contrast media volume ratio greater than or equal to 17 (AUC = 0.57) were the best thresholds for freedom from CA-AKI. CONCLUSIONS: In our comprehensive pooled analysis, an absolute volume expansion greater than or equal to 1430 mL and a volume expansion to contrast media volume ratio greater than or equal to 17 are the best dichotomous thresholds for CA-AKI prevention. These cutoffs should be formally tested in a dedicated trial as a pragmatic means to prevent CA-AKI.

Repeat coronary revascularization is a common adverse event after successful percutaneous coronary intervention. This analysis aimed to assess the effects of ticagrelor monotherapy on repeat clinically driven revascularization (CDR). In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients after Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, high-risk patients were maintained on ticagrelor and randomly allocated to aspirin or placebo for 1 year. The primary end point of this analysis was CDR within 12 months after randomization. The key secondary end points were major adverse cardiovascular and cerebrovascular events (MACCEs), a composite of all-cause death, myocardial infarction, stroke, or CDR, and net adverse clinical events (NACEs), including the individual components of MACCEs and clinically relevant bleeding. The analysis was performed in the per-protocol population. CDR occurred in 473 of 7,039 patients and was associated with a significantly higher risk of subsequent all-cause death, myocardial infarction, or stroke (adjusted hazard ratios [HRs] 2.92, 95% confidence interval [CI] 1.82 to 4.67). Ticagrelor monotherapy was associated with a similar 12-month risk of CDR (7.1% vs 6.6%; HR 1.09, 95% CI 0.90 to 1.30, p = 0.363) and MACCEs (8.9% vs 8.6%; HR 1.04, 95% CI 0.89 to 1.22, p = 0.619), and a lower risk of NACEs (12.2% vs 14.6%; HR 0.83 95% CI 0.73 to 0.94, p = 0.004) than ticagrelor plus aspirin. In conclusion, among high-risk patients who underwent percutaneous coronary intervention, ticagrelor monotherapy after 3 months of ticagrelor-based dual antiplatelet therapy was associated with a similar risk of CDR and MACCEs and a decrease of NACEs (TWILIGHT: NCT02270242).

BACKGROUND: Nearly 20% of patients on ticagrelor experience dyspnea, which may lead to treatment discontinuation in up to one-third of cases. OBJECTIVES: The authors sought to evaluate the incidence, predictors, and outcomes of dyspnea-related ticagrelor discontinuation after percutaneous coronary intervention (PCI). METHODS: In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. The occurrence of dyspnea associated with ticagrelor discontinuation was evaluated among all patients enrolled in the trial. A landmark analysis was performed at 3 months after PCI, that is, the time of randomization. Predictors of dyspnea-related ticagrelor discontinuation were obtained from multivariable Cox regression with stepwise selection of candidate variables. RESULTS: The incidence of dyspnea-related ticagrelor discontinuation was 6.4% and 9.1% at 3 and 15 months after PCI, respectively. Independent predictors included Asian race (lower risk), smoking, prior PCI, hypercholesterolemia, prior coronary artery bypass, peripheral artery disease, obesity, and older age. Among 179 patients who discontinued ticagrelor because of dyspnea after randomization, ticagrelor monotherapy was not associated with a higher risk of subsequent ischemic events (composite of all-cause death, myocardial infarction, or stroke) compared with ticagrelor plus aspirin (5.0% vs 7.1%; P = 0.566). CONCLUSIONS: In the TWILIGHT trial, dyspnea-related ticagrelor discontinuation occurred in almost 1 in 10 patients and tended to occur earlier rather than late after PCI. Several demographic and clinical conditions predicted its occurrence, and their assessment may help identify subjects at risk for therapy nonadherence.

AIMS: The role of coronary calcification on clinical outcomes among different revascularization strategies in patients presenting with acute coronary syndromes (ACSs) has been rarely investigated. The aim of this investigation is to evaluate the role of coronary calcification, detected by coronary angiography, in the whole spectrum of patients presenting with acute ACS. METHODS AND RESULTS: The present study was a post hoc analysis of the MATRIX programme. The primary endpoint was major adverse cardiovascular events (MACE), defined as the composite of all-cause mortality, myocardial infarction (MI), or stroke up to 365 days. Among the 8404 patients randomized in the MATRIX trial, data about coronary calcification were available in 7446 (88.6%) and therefore were included in this post hoc analysis. Overall, 875 patients (11.7%) presented with severe coronary calcification, while 6571 patients (88.3%) did not present severe coronary calcification on coronary angiography. Fewer patients with severe coronary calcification underwent percutaneous coronary intervention whereas coronary artery bypass grafting or medical therapy-only was more frequent compared with patients without severe calcification. At 1-year follow-up, MACE occurred in 237 (27.1%) patients with severe calcified coronary lesions and 985 (15%) patients without severe coronary calcified lesions [hazard ratio (HR) 1.91; 95% confidence interval (CI) 1.66-2.20, P < 0.001]. All-cause mortality was 8.6% in patients presenting with and 3.7% in those without severe coronary calcification (HR 2.38, 1.84-3.09, P < 0.001). Patients with severe coronary calcification incurred higher rate of MI (20.1% vs. 11.5%, HR 1.81; 95% CI 1.53-2.1, P < 0.001) and similar rate of stroke (0.8% vs. 0.6%, HR 1.35; 95% CI 0.61-3.02, P = 0.46). CONCLUSION: Patients with ACS and severe coronary calcification, as compared to those without, are associated with worse clinical outcomes irrespective of the management strategy.

There is a paucity of data regarding the safety of a 1-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients at high bleeding risk (HBR) presenting with acute coronary syndromes (ACS). We aimed to compare the clinical outcomes of patients at HBR with chronic coronary syndrome (CCS) or ACS treated with PCI using bioresorbable polymer everolimus-eluting stent (BP-EES) followed by 1-month DAPT. Patients at HBR who underwent PCI with BP-EES were prospectively enrolled in 10 Italian centers. All patients were treated with 1-month DAPT. In case of need for anticoagulation, patients received an oral anticoagulant in addition to a P2Y12 inhibitor for 1 month, followed by oral anticoagulation only after that. The primary end point was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis at 12 months. Overall, 263 patients (59.4%) with CCS and 180 patients (40.6%) with ACS were enrolled. No significant difference was evident between patients with CCS and ACS for the primary end point (4.3% vs 5.6%, respectively, p = 0.497) and for each isolated component. The risk for Bleeding Academic Research Consortium (BARC) type 1 to 5 or type 3 to 5 bleedings was also similar between patients with CCS and ACS (4.3% vs 5.2%, p = 0.677, and 1.6% vs 2.9%, p = 0.351, respectively). In conclusion, among HBR patients with ACS who underwent PCI with BP-EES, a 1-month DAPT strategy is associated with a similar risk of ischemic and bleeding events compared with those with CCS.

BACKGROUND: Contrast associated acute kidney injury (CA-AKI) can lead to an increased risk of adverse events. Contrast media (CM) volume reduction has been advocated as a pivotal strategy to prevent CA-AKI in stable patients undergoing percutaneous coronary procedures. AIMS: To compare the effectiveness of CM volume reduction with the DyeVertTM system versus conventional strategy in reducing the risk of CA-AKI. METHODS: We prospectively collected data from 136 patients with stable coronary artery disease at high risk of CA-AKI treated with left ventricular end diastolic pressure (LVEDP)- guided hydration and undergoing interventions with the use of the DyeVertTM (Osprey Medical Inc.) system. Patients previously enrolled in the LVEDP-guided hydration arm of the "Renal Insufficiency Following Contrast MEDIA Administration triaL III" (REMEDIAL III) were considered as controls. Propensity score was used to perform 1:1 matching to adjust for major confounders. The primary outcome was the occurrence of CA-AKI, as defined by an absolute increase of creatinine values ≥0.3 mg/dL at 48 h. RESULTS: Patients in the DyeVert group were treated with a significant lower CM volume (median: 47.5 vs. 84.0 mL, p < 0.001). The trend in creatinine increase was lower (p = 0.004) and the Δ of creatinine (0-48 h) showed a higher drop (-0.18 vs. -0.10 mg/dL, p = 0.036) in the DyeVert group. The risk of CA-AKI was significantly lower in DyeVert group compared to control group (5.1% vs. 16.8%; odds ratio 0.27, 95% confidence interval [0.12-0.61]). CONCLUSIONS: CM volume reduction with the DyeVertTM system seems to be superior to conventional strategies in reducing the occurrence of CA-AKI.

BACKGROUND: In TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention), among high-risk patients undergoing percutaneous coronary intervention (PCI), ticagrelor monotherapy vs continuation of dual antiplatelet therapy (DAPT) with aspirin and ticagrelor after completing a 3-month course of DAPT was associated with reduced bleeding, without an increase in ischemic events. OBJECTIVES: This investigation sought to study the clinical benefit of ticagrelor monotherapy vs DAPT by simultaneously modeling its associated potential bleeding benefits and ischemic harms on an individual patient basis. METHODS: Multivariable Cox regression models for: 1) Bleeding Academic Research Consortium type 2, 3, or 5 (BARC-2/3/5); and 2) cardiovascular death, nonfatal myocardial infarction, and nonfatal ischemic stroke (major adverse cardiac and cerebrovascular event [MACCE]) were developed using stepwise forward variable selection. The coefficients in the BARC-2/3/5 and MACCE models were used to calculate bleeding and ischemic risk scores, respectively, for each patient (excluding the coefficient for randomized treatment). RESULTS: In the total study group (N = 7,119), BARC-2/3/5 occurred in 391 (5.5%) patients, and MACCE occurred in 258 (3.6%). There was a consistent reduction in bleeding events associated with ticagrelor monotherapy compared with DAPT across both bleeding and ischemic risk strata (P interaction = 0.54 and 0.11, respectively). Importantly, this benefit associated with ticagrelor monotherapy was not offset by an increase in MACCE at any level of bleeding or ischemic risk. CONCLUSIONS: Three months after PCI, discontinuing aspirin and maintaining ticagrelor monotherapy reduces bleeding in both higher-bleeding risk and lower-bleeding risk patients compared with continued DAPT. This benefit does not appear to be offset by greater ischemic risk. (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention [TWILIGHT]; NCT02270242).

BACKGROUND: A simple, contemporary risk score for the prediction of contrast-associated acute kidney injury (CA-AKI) after percutaneous coronary intervention (PCI) was recently updated, although its external validation is lacking. OBJECTIVES: The aim of this study was to validate the updated CA-AKI risk score in a large cohort of acute coronary syndrome patients from the MATRIX (Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of angioX) trial. METHODS: The risk score identifies 4 risk categories for CA-AKI. The primary endpoint was to appraise the receiver-operating characteristics of an 8-component and a 12-component CA-AKI model. Independent predictors of Kidney Disease Improving Global Outcomes-based acute kidney injury and the impact of CA-AKI on 1-year mortality and bleeding were also investigated. RESULTS: The MATRIX trial included 8,201 patients with complete creatinine values and no end-stage renal disease. CA-AKI occurred in 5.5% of the patients, with a stepwise increase of CA-AKI rates from the lowest to the highest of the 4 risk categories. The receiver-operating characteristic area under the curve was 0.67 (95% CI: 0.64-0.70) with model 1 and 0.71 (95% CI: 0.68-0.74) with model 2. CA-AKI risk was systematically overestimated with both models (Hosmer-Lemeshow goodness-of-fit test: P < 0.05). The 1-year risks of all-cause mortality and bleeding were higher in CA-AKI patients (HR: 7.03 [95% CI: 5.47-9.05] and HR: 3.20 [95% CI: 2.56-3.99]; respectively). There was a gradual risk increase for mortality and bleeding as a function of the CA-AKI risk category for both models. CONCLUSIONS: The updated CA-AKI risk score identifies patients at incremental risks of acute kidney injury, bleeding, and mortality.

BACKGROUND: Body mass index (BMI) is a known confounder for natriuretic peptides, but its influence on other biomarkers is less well described. We investigated whether BMI interacts with biomarkers' association with prognosis in patients with acute heart failure (AHF). METHODS AND RESULTS: B-type natriuretic peptide (BNP), high-sensitivity cardiac troponin I (hs-cTnI), galectin-3, serum neutrophil gelatinase-associated lipocalin (sNGAL), and urine NGAL were measured serially in patients with AHF during hospitalization in the AKINESIS (Acute Kidney Injury Neutrophil gelatinase-associated lipocalin Evaluation of Symptomatic Heart Failure) study. Cox regression analysis was used to determine the association of biomarkers and their interaction with BMI for 30-day, 90-day and 1-year composite outcomes of death or HF readmission. Among 866 patients, 21.2%, 29.7% and 46.8% had normal (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2) or obese (≥ 30 kg/m2) BMIs on admission, respectively. Admission values of BNP and hs-cTnI were negatively associated with BMI, whereas galectin-3 and sNGAL were positively associated with BMI. Admission BNP and hs-cTnI levels were associated with the composite outcome within 30 days, 90 days and 1 year. Only BNP had a significant interaction with BMI. When BNP was analyzed by BMI category, its association with the composite outcome attenuated at higher BMIs and was no longer significant in obese individuals. Findings were similar when evaluated by the last-measured biomarkers and BMIs. CONCLUSIONS: In patients with AHF, only BNP had a significant interaction with BMI for the outcomes, with its association attenuating as BMI increased; hs-cTnI was prognostic, regardless of BMI.
