RESUMO

BACKGROUND: Malnutrition is associated with poor prognosis in several cardiovascular diseases; however, its role in patients with secondary mitral regurgitation (SMR) is poorly known. AIMS: To evaluate the impact of nutritional status, assessed using different scores, on clinical outcomes in patients with SMR undergoing transcatheter edge-to-edge repair (TEER) in a real-world setting. METHODS: A total of 658 patients with SMR and complete nutritional data were identified from the MIVNUT registry. Nutritional status has been assessed using controlling nutritional status index (CONUT), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) scores. Outcomes of interest were all-cause mortality and all-cause mortality or heart failure (HF) hospitalization. RESULTS: Any malnutrition grade was observed in 79.4%, 16.7%, and 47.9% of patients by using CONUT, PNI, and GNRI, respectively, while moderate to severe malnutrition was noted in 24.7%, 16.7%, and 25.6% of patients, respectively. At a median follow-up of 2.2 years, 212 patients (32.2%) died. Moderate-severe malnutrition was associated with a higher rate of all-cause mortality (HR: 2.46 [95% CI: 1.69-3.58], HR: 2.18 [95% CI: 1.46-3.26], HR: 1.97 [95% CI: 1.41-2.74] for CONUT, PNI, and GNRI scores, respectively). The combined secondary endpoint of all-cause mortality and HF rehospitalization occurred in 306 patients (46.5%). Patients with moderate-severe malnutrition had a higher risk of the composite endpoint (HR: 1.56 [95% CI: 1.20-2.28], HR: 1.55 [95% CI: 1.01-2.19], HR: 1.36 [95% CI: 1.02-1.80] for CONUT, PNI, and GNRI scores, respectively). After adjustment for multiple confounders, moderate-severe malnutrition remained independently associated with clinical outcomes. CONCLUSIONS: Moderate-severe malnutrition was common in patients with SMR undergoing TEER. It was independently associated with poor prognosis regardless of the different scores used.

RESUMO

Celiac disease (CD) is an inflammatory intestinal disease caused by the ingestion of gluten-containing cereals by genetically predisposed individuals. Constitutive differences between cells from CD patients and control subjects, including levels of protein phosphorylation, alterations of vesicular trafficking, and regulation of type 2 transglutaminase (TG2), have been reported. In the present work, we investigated how skin-derived fibroblasts from CD and control subjects responded to thapsigargin, an endoplasmic reticulum ER stress inducer, in an attempt to contribute to the comprehension of molecular features of the CD cellular phenotype. We analyzed Ca2+ levels by single-cell video-imaging and TG2 activity by a microplate assay. Western blots and PCR analyses were employed to monitor TG2 levels and markers of ER stress and autophagy. We found that the cytosolic and ER Ca2+ level of CD cells was lower than in control cells. Treatments with thapsigargin differently activated TG2 in control and CD cells, as well as caused slightly different responses regarding the activation of ER stress and the expression of autophagic markers. On the whole, our findings identified further molecular features of the celiac cellular phenotype and highlighted that CD cells appeared less capable of adapting to a stress condition and responding in a physiological way.

RESUMO

BACKGROUND: The optimal antithrombotic regimen in patients with a concomitant indication for oral anticoagulation (OAT) presenting with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) remains unclear. OBJECTIVES: To perform a network meta-analysis of all randomized controlled trials (RCTs) evaluating different antithrombotic regimens among patients with ACS or undergoing PCI requiring OAT. METHODS: Network meta-analysis was performed in a frequentist framework. Antithrombotic regimens were categorized by OAC type (vitamin K antagonist-based [VKA]; non-VKA OAT [NOAC]) and antiplatelet agents (P2Y inhibitor only: dual therapy [DAT]; P2Y plus aspirin: triple therapy [TAT]). Safety outcomes were Thrombolysis in Myocardial Infarction (TIMI) major bleeding and intracranial hemorrhage (ICH). Efficacy outcomes were cardiovascular death, myocardial infarction, stroke and stent-thrombosis (ST). RESULTS: Five RCTs were included, encompassing 10,797 patients (atrial fibrillation 69-100%, ACS 28-62%, PCI 77-100%). Both VKA and NOAC-based DAT regimens reduced the occurrence of TIMI major bleeding compared to VKA TAT (VKA DAT: RR 0.62, 95% CI 0.39-0.98; NOAC DAT: RR 0.52, 95% CI 0.39-0.70). Nevertheless, only NOAC DAT significantly reduced the occurrence of ICH compared to VKA TAT (RR 0.33, 95% CI 0.17-0.64). Ischemic outcomes were similar among the four treatment regimens. However, numerical, potentially clinically important, higher ST occurrence was observed for NOAC DAT as compared to both VKA TAT (1.50, 95% confidence interval [CI] 0.96-2.33) and NOAC TAT (1.86, 95% CI 0.93-3.73). CONCLUSION: DAT regimens present the highest safety profile among antithrombotic strategies, with a NOAC-specific impact on ICH reduction. NOAC DAT might entail clinically important higher ST occurrence, warranting a case-by-case comprehensive evaluation that integrates patient- and procedure-related residual ischemic risk with the patient-specific bleeding risk.

RESUMO

BACKGROUND: Clinical benefits of FFR (Fraction Flow Reserve) driven CABG (Coronary Artery Bypass Graft) remain to be established. METHODS: All randomized controlled trials (RCTs) and observational studies with multivariable adjustement were included. MACE (Major Adverse Cardiac Events) was the primary end point, while its single components (death, myocardial infarction, and total vessel revascularization [TVR]) along with number of anastomoses, on pump procedures and graft occlusion at angiographic follow-up were the secondary ones. Each analysis was stratified for RCTs versus observational studies. RESULTS: Four studies (two RCTs and two observational) were included, enrolling 983 patients, 542 angio-guided and 441 FFR-guided. Mean age was 68.45 years, 79% male, with a mean EuroSCORE I of 2.7. Coronary lesions were located in 37% of patients in the left anterior descending artery, 32% in the circumflex artery, and 26% in the right coronary artery. After a mean follow-up of 40 months, risk of MACE did not differ (OR 0.86 [0.63-1.18]) as that of all cause death (OR 0.86 [0.59-1.25]), MI (OR 0.57 [0.30-1.11]) and TVR (OR 1.10 [0.65-1.85]). FFR-driven CABG reduced on-pump procedures (OR 0.58 [0.35-0.93]) and number of anastomoses (-0.40 [-0.80: -0.01]) while incidence of graft occlusion at follow-up did not differ (OR 0.59 [0.30-1.15], all CI 95%). CONCLUSION: Fraction flow reserve driven CABG reduced the number of anastomoses and of on-pump procedures without increasing risk of MACE and without reducing graft occlusion at angiographic follow-up.

RESUMO

BACKGROUND: The optimal approach to guide percutaneous coronary intervention (PCI) has yet to be defined. The aim of this study was to compare functional driven (fractional flow reserve) versus intravascular imaging (intravascular ultrasound, IVUS, and/or optical coherence tomography, OCT) versus standard (coronary angiography only, CA)-guided PCI. METHODS: Randomized controlled trials (RCTs) and propensity score weight-matched studies (PSWMs) comparing FFR versus IVUS versus OCT versus CA-guided PCI were included. Major adverse cardiovascular event (MACE; a composite end point of death or myocardial infarction [MI] or revascularization) was the primary endpoint, whereas definite stent thrombosis (ST) and single components of MACE were the secondary ones. Primary analyses were performed including only RCTs, secondary also with PSWMs. RESULTS: Thirty-three studies were included in the analysis, 16 RCTs and 17 PSWMs. After 2 (1-3) years, IVUS performed better for MACE than CA (odds ratio [OR] 0.75 0.52-0.88), whereas there was just a trend for FFR (OR 0.81, 0.64-1.02). These results were mainly driven by reduced risk of all cause death, MI (FFR OR 0.74:0.57-0.99 and IVUS OR 0.82:0.54-0.94) and revascularization. IVUS reduced ST while FFR did not, and at meta-regression analysis, there was a trend for superiority of IVUS versus FFR to reduce subsequent MI in acute coronary syndrome (ACS) patients. The present results were consistent also after adding studies with PSWMs. CONCLUSIONS: Functional and intravascular imaging approaches seem to perform similarly in term of clinical outcomes, while both performed better compared with the standard approach. Imaging showed a potential benefit for ACS patients. The present results stress the need for a wider use of functional or imaging driven PCI.

RESUMO

OBJECTIVES: To compare the effectiveness and safety of self-expandable, sirolimus-eluting Stentys stents (SES) and second-generation drug-eluting stents (DES-II) for the treatment of the unprotected left main (ULM). BACKGROUND: SES may provide a valuable option to treat distal ULM, particularly when significant caliber gaps with side branches are observed. METHODS: Patients from the multicenter SPARTA (clinicaltrials.gov: NCT02784405) and FAILS2 registries were included. Propensity-score with matching was performed to account for the lack of randomization. Primary end-point was the rate of major adverse cardiovascular events (MACE, a composite of all cause death, myocardial infarction, target lesion revascularization [TLR], unstable angina and definite stent thrombosis [ST]). Single components of MACE were the secondary end-points. RESULTS: Overall, 151 patients treated with SES and 1270 with DES-II were included; no differences in MACE rate at 250 days were observed (9.8% vs. 11.5%, P = 0.54). After propensity score with matching, 129 patients treated with SES and 258 with DES-II, of which about a third of female gender, were compared. After a follow-up of 250 days, MACE rate did not differ between the two groups (9.9% vs. 8.5%, P = 0.66), as well as the rate of ULM TLR (1.6% vs. 3.1%, P = 0.36) and definite ST (0.8% vs. 1.2%, P = 0.78). These results were consistent also when controlling for the treatment with provisional vs. 2-stents strategies for the ULM bifurcation. CONCLUSION: SES use for ULM treatment was associated with a similar MACE rate compared to DES-II at an intermediate-term follow-up. SES might represent a potential option in this setting.

RESUMO

OBJECTIVES: Culprit plaque characteristics in young patients who experience an Acute Coronary Syndrome (ACS) evaluated by OCT (Optical Coherence Tomography) have to be defined. The OCT-FORMIDABLE is a multicentre retrospective registry enrolling consecutive patients with ACS who performed OCT in 9 European centres. METHODS: Patients were divided in two groups according to age at presentation: juvenile-ACS (age ≤ 50 years) and not juvenile-ACS (age > 50 years). Primary end-point was the prevalence of plaque rupture (PR). Secondary end point was the prevalence of thin cap fibro atheroma (TCFA), fibrocalcific and fibrotic plaque. RESULTS: 285 patients were included, 71 (24.9%) in juvenile-ACS group and 215 (75.1%) in not juvenile-ACS group. Younger patients showed a trend for a higher prevalence of TCFA (70 vs. 58%, P = 0.06) and thrombus presence (62 vs. 51%, P = 0.1), while no statistical difference concerning PR (70 vs. 64%, P = 0.29). Of interest patients younger that 35 years showed a higher prevalence of PR compared to patients aged between 35 and 45 or 45 and 50 years (100 vs. 72 vs. 55%, P = 0.03). Culprit plaque in juvenile-ACS group showed more frequently a reduced mean cap thickness (119 ± 66 vs. 155 ± 95 nm, P = 0.05) and less frequently fibrotic (32 vs. 57%, P < 0.001) or fibrocalcific (17 vs. 36%, P = 0.003) characteristics. CONCLUSION: young patients with ACS show a trend for a higher prevalence of culprit PR, a thinner cap and less fibrotic or fibrocalcific components.

RESUMO

AIMS: Instantaneous free-wave ratio (iFR) has been recently demonstrated non-inferior to fractional flow reserve (FFR) to drive coronary revascularization; however, no study has compared iFR versus coronary angiography (CA). We performed a network meta-analysis to evaluate efficacy and safety of iFR- versus CA-guided strategy. METHODS AND RESULTS: We searched for randomized trials and studies with propensity score matching in The Cochrane Collaboration Central Register of Controlled Trials, EMBASE, and MEDLINE/Pubmed. CA, FFR, and iFR were the three competitive arms, MACE (a composite endpoint of death, myocardial infarction [MI], and target vessel revascularization [TVR]) was the primary endpoint, while its single components the secondary ones. Subgroup analysis was performed for patients presenting with stable coronary artery disease. Eight studies were selected: 4126 patients were evaluated with FFR, 2160 with iFR, and 2214 with CA, acute coronary syndrome (ACS) was the most frequent admission diagnosis. After 12 months, rates of MACE and all-cause death did not differ between groups (respectively OR 1.04 and OR 0.86 for iFR vs FFR). Both FFR and iFR reduced TVR compared to CA (respectively OR 0.68 and OR 0.70). In patients with stable CAD both FFR and iFR reduced risk of subsequent MI compared to CA (respectively OR 0.66 and OR 0.79). CONCLUSION: Compared to CA alone, both FFR and iFR are safe and effective in guiding coronary revascularization at 12 months. In patients with stable CAD, both FFR and iFR-guided revascularization reduce the risk of subsequent MI at 12 months.

RESUMO

BACKGROUND: The risk/benefit balance of transcatheter aortic valve implantation (TAVI) in patients with low-gradient aortic stenosis (LGAS) remains to be well defined. Aim of the study was to investigate the impact of LGAS in patients undergoing TAVI. METHODS: Medline, Cochrane Library, and Scopus were searched for articles reporting outcome of patients with LGAS undergoing TAVI. The primary endpoint was 12-months all-cause mortality and the secondary endpoint was 30-day all-cause mortality. Using event-rates as dependent variable, a meta-regression was performed to test for interaction between baseline clinical features (age, gender, diabetes mellitus, coronary artery disease, left ventricular ejection fraction (LVEF) and type of implanted valve) and transaortic gradient for the primary endpoint. RESULTS: Eight studies with a total of 12,589 patients were included. Almost one-third of the patients presented with LGAS (27.3%: 24.4-29.2). Median LVEF was 48% in patients with LGAS and 56% in patients with high-gradient AS. Patients with LGAS were more likely to have diabetes mellitus, previous coronary artery disease, higher mean Logistic EuroSCORE, and lower EF. At 12 (12-16.6) months, low transaortic gradient emerged as independently associated with all-cause death, both if evaluated as a dichotomous and continuous value (respectively OR 1.17; 1.11-1.23 and OR 1.02; 1-1.04, all CI 95%). Clinical variables, including EF did not affect this result. CONCLUSIONS: In a population of TAVI patients, LGAS appears to be independently related to dismal prognosis. © 2016 Wiley Periodicals, Inc.

RESUMO

AIM: To determine the potential clinical impact of OCT (Optical Coherence Tomography) during primary percutaneous coronary intervention in patients presenting with ACS (Acute Coronary Syndrome). METHODS AND RESULTS: FORMIDABLE is a multicentre retrospective registry enrolling all patients presenting with ACS and treated with an OCT-guided approach, while the USZ registry enrolled patients treated with a standard angiography guided approach. Multivariate adjustment was performed via a propensity score matching. The number stents useds was the primary outcome, while the incidence of MACE (a composite of death, myocardial infarction, target vessel revascularization, and stent thrombosis) was the secondary endpoint. A total of 285 patients OCT-guided and 1,547 angiography guided patients were enrolled, resulting in 270 for each cohort after propensity score with matching. Two stents were used in 12% versus 34%; 3 stents in 8% versus 38% of the patients (P < 0.001). After a follow up of 700 days (450-890), there was no difference in myocardial infarction (6% vs. 6%, P = 0.86), while MACE (11% vs. 16%, P = 0.06), target vessel revascularization (2% vs. 4%, P = 0.15) and stent thrombosis rates (0% vs. 2.7%, P = 0.26) were numerically lower for the OCT-guided cohort but none of these endpoints did reach statistical significance. CONCLUSIONS: An OCT-guided approach reduced the number of stents used, number of patients treated with more than one stent, while there was no statistically significant difference in clinical endpoints while most of them were numerically lower, including stent thrombosis rates. © 2016 Wiley Periodicals, Inc.

RESUMO

The efficacy and safety of different statins for human immunodeficiency virus (HIV)-positive patients in the primary prevention setting remain to be established. In the present meta-analysis, 18 studies with 736 HIV-positive patients receiving combination antiretroviral therapy (cART) and treated with statins in the primary prevention setting were included (21.0% women, median age 44.1 years old). The primary endpoint was the effect of statin therapy on total cholesterol (TC) levels. Rosuvastatin 10 mg and atorvastatin 10 mg provided the largest reduction in TC levels [mean -1.67, 95% confidence interval (CI) (-1.99, -1.35) mmol/L; and mean -1.44, 95% CI (-1.85, -1.02) mmol/L, respectively]. Atorvastatin 80 mg and simvastatin 20 mg provided the largest reduction in low-density lipoprotein (LDL) [mean -2.10, 95% CI (-3.39, -0.81) mmol/L; and mean -1.57, 95% CI (-2.67, -0.47) mmol/L, respectively]. Pravastatin 10-20 mg [mean 0.24, 95% CI (0.10, 0.38) mmol/L] and atorvastatin 10 mg [mean 0.15, 95% CI (0.007, 0.23) mmol/L] had the largest increase in high-density lipoprotein, whereas atorvastatin 80 mg [mean -0.60, 95% CI (-1.09, -0.11) mmol/L] and simvastatin 20 mg [mean -0.61, 95% CI (-1.14, -0.08) mmol/L] had the largest reduction in triglycerides. The mean discontinuation rate was 0.12 per 100 person-years [95% CI (0.05, 0.20)], and was higher with atorvastatin 10 mg [26.5 per 100 person-years, 95% CI (-13.4, 64.7)]. Meta-regression revealed that nucleoside reverse transcriptase inhibitors-sparing regimens were associated with reduced efficacy for statin's ability to lower TC. Statin therapy significantly lowers plasma TC and LDL levels in HIV-positive patients and is associated with low rates of adverse events. Statins are effective and safe when dose-adjusted for drug-drug interactions with cART.

RESUMO

INTRODUCTION: Accuracy of intracoronary imaging to discriminate functionally significant coronary stenosis according to vessel diameter remains to be defined. METHODS: PubMed, Scopus, and Google Scholar were systematically searched for studies assessing diagnostic accuracy (area under the receiver operating characteristic curve [AUC], the primary end point) and sensitivity and specificity (the secondary end points) of minimal luminal area (MLA) or of minimal luminal diameter (MLD) derived from intravascular ultrasound (IVUS) or optical coherence tomography (OCT) to detect functionally significant stenosis as determined with fractional flow reserve (FFR). RESULTS: Fifteen studies were included, 2 with 110 patients analyzing only left main (LM), 5 with 224 patients and 306 lesions using OCT, and 9 with 1532 patients and 1681 lesions with IVUS. Median MLA for the OCT studies was 1.96 mm(2) (1.85-1.98 mm(2)), 2.9 mm(2) (2.7-3.1 mm(2)) for MLA of all lesions assessed with IVUS, 2.8 mm(2) (2.7-2.9 mm(2)) for lesions with an angiographic diameter >3 mm, 2.4 mm(2) (2.4-2.5 mm(2)) for lesions <3 mm, and 5.4 mm(2) (5.1-5.6 mm(2)) for LM lesions. For OCT-MLA, AUC was 0.80 (0.74-0.86), with a sensitivity of 0.81 (0.74-0.87) and specificity of 0.77 (0.71-0.83), whereas OCT-MLD had an AUC of 0.85 (0.79-0.91), sensitivity of 0.74 (0.69-0.78), and specificity of 0.70 (0.68-0.73). For IVUS-MLA, AUC was 0.78 (0.75-0.81) for all lesions, 0.78 (0.73-0.84) for vessels with a diameter >3 mm, and 0.79 (0.70-0.89) for those with a diameter <3 mm. Left main AUC was 0.97 (0.93-1). CONCLUSION: Intravascular ultrasound and OCT had modest diagnostic accuracy for identification hemodynamically significant lesions, also with specific cutoff for different diameters. Invasive imaging for assessment of LM severity demonstrated excellent correlation with FFR. What is already known about this subject? Fractional flow reserve represents the criterion standard to evaluate the prognostic value of coronary stenosis, whereas its relationship with IVUS and OCT remains to be assessed. What does this study add? Despite improvement, IVUS and OCT do not predict functional stenosis, even with dedicated cutoff, apart from LM disease. How might this impact on clinical practice? The recent guidelines of myocardial revascularization have stressed the crucial role of FFR before performing percutaneous coronary intervention on LM, whereas intravascular imaging is often exploited to drive revascularization. The present analysis stresses the point that LM percutaneous coronary intervention may be driven only by intravascular imaging, given the high accuracy for significant ischemic lesions, whereas for other vessels, these 2 techniques mirror 2 different aspects.

RESUMO

The present work focuses on the production of electrospun membranes based on Poly(ε-caprolactone) (PCL) and Polyvinylpyrrolidone (PVP) for the topical release of Quercetin (Q). Membranes were prepared at 0.5, 1.0, 3.0, 7.0 and 15 % wt of Quercetin and studied from a morphological, physical, and biological point of view. The scanning electron microscopy (SEM) evidences micrometric dimensions of the fibres with a good dispersion of the functional molecule. The retention degree of liquids was evaluated by testing four different liquid media while the radical scavenging activity of Quercetin-loaded membranes was evaluated through DPPH analysis. The release kinetics of Quercetin highlights the presence of an initial burst followed by slower release up to attaining an equilibrium state, after roughly 50 h, showing the possibility of a fine-tuning of drug release. Diffusion coefficients were then evaluated by using Fick's law. Finally, to verify the actual biocompatibility of the systems produced and the possible application in the repair of tissue injury, the biological activity of Quercetin released from drug-loaded membranes was analysed in an immortalized human keratinocyte cell line HaCaT by a wound healing assay. So, the reported preliminary data confirm the possibility of applying the electrospun Quercetin-loaded PCL-PVP membranes for wound healing applications.

RESUMO

An 84-year-old man presented with dyspnea at rest due to severe mitral regurgitation. He first underwent transventricular mitral valve repair with the Harpoon system, which relapsed owing to rupture of neochords. He was definitively treated with transcatheter mitral valve implantation of the Tendyne system 8 months later.

RESUMO

BACKGROUND: Hemodynamic assessment can be determinant in phenotyping cardiogenic shock (CS) and guiding patient management. Aim of this study was to evaluate the correlation between echocardiographic and invasive assessment of hemodynamics in acute decompensated heart failure-related CS (ADHF-CS). METHODS: All consecutive ADHF-CS patients (SCAI shock stage ≥B) undergoing right heart catheterization (RHC) between 2020 and 2022 were prospectively enrolled. Patients underwent echocardiography 30 minutes before RHC. The evaluated hemodynamic parameters and their echocardiographic estimates ("e") comprised cardiac index (CI), wedge pressure (WP), pulmonary artery pressures (PAP), cardiac power output (CPO) and pulmonary artery pulsatility index (PAPi). RESULTS: 101 ADHF-CS patients (56±11 years, 64% SCAI shock stage C, left ventricular ejection fraction 29±5%) were included. Good correlation was found for CI, systolic PAP, RAP and CPO (Pearson r > 0.8 for all), moderate correlation for ePAPi (r=0.67) and PVR (r=0.51), while estimation of WP was weak. The sensitivity and specificity of eCI to identify low output state (CI ≤2.2 l/min/m2) were 0.97 and 0.73 respectively, those of eWP for elevated filling pressures (WP >15 mmHg) were 0.84 and 0.55, those of ePAPs for PAPs ≥35 mmHg were 0.87 and 0.63, those of eCPO for CPO<0.6 W were 0.76 and 0.85, those of ePAPi for PAPi <1.85 were 0.89 and 0.92. Echocardiographic phenotyping of CS showed a good agreement with invasive classification (K value 0.457, p<0.001). CONCLUSIONS: Echocardiographic estimation of hemodynamics and subsequent phenotypization of CS is feasible with good agreement with invasive evaluation.

RESUMO

Background: Risk scores may identify patients with mitral regurgitation (MR) who are at risk for adverse events, but who may still benefit from transcatheter edge-to-edge repair (TEER). We sought to cross-validate the MitraScore and COAPT risk score to predict adverse events in patients undergoing TEER. Methods: MitraScore validation was carried out in the COAPT population which included 614 patients with FMR who were randomized 1:1 to guideline-directed medical therapy (GDMT) with or without TEER and were followed for 2 years. Validation of the COAPT risk score was carried out in 1007 patients from the MIVNUT registry of TEER-treated patients with both FMR and degenerative MR who were followed for a mean of 2.1 years. The predictive value was assessed using the area under the receiver operating characteristic curve (AUC) plots. The primary outcome was all-cause mortality. Results: The MitraScore had fair to good predictive accuracy for mortality in the overall COAPT trial population (AUC, 0.67); its accuracy was higher in patients treated with TEER (AUC, 0.74) than GDMT alone (AUC, 0.65). The COAPT risk score had fair predictive accuracy for death in the overall MitraScore cohort (AUC, 0.64), which was similar in patients with FMR and degenerative MR (AUC, 0.64 and 0.66, respectively). There was a consistent benefit of treatment with TEER plus GDMT compared with GDMT alone in the COAPT trial population across all MitraScore risk strata. Conclusions: The COAPT risk score and MitraScore are simple tools that are useful for the prediction of 2-year mortality in patients eligible for or undergoing treatment with TEER.

RESUMO

INTRODUCTION: For acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI), the choice of the duration and kind of dual antiplatelet therapy (DAPT) offering the most accurate balance between ischemic and bleeding risk remains unknown. EVIDENCE ACQUISITION: A network meta-analysis was performed including all Randomized Controlled Trials (RCTs) comparing different DAPT regimens and duration in ACS patients undergoing PCI. Trial-defined MACE and major bleedings were the primary endpoints. Stroke, stent thrombosis (ST), all-cause and cardiovascular death, myocardial infarction (MI) represented secondary endpoints. EVIDENCE SYNTHESIS: 13 RCTs encompassing 46145 patients were included. Mean age was 62 (61-64) years old, 42% being admitted with STEMI, 33% with NSTEMI and 25% with UA. The competitive arms were: clopidogrel and aspirin for 12 months (6 arms/18183 patients), clopidogrel and aspirin for 6 months (4/3329), clopidogrel and aspirin >12 months (3/2238), ticagrelor and aspirin for 12 months (6/12942) and prasugrel and aspirin for 12 months (3/9453). Trial-defined MACE and major bleedings, stroke and death were similar among the different arms. DAPT with prasugrel and aspirin for 12 months reduced MI compared to aspirin and clopidogrel for 12 months (OR 0.71, 95% CI: 0.54.0.94) and reduced the risk of ST compared to ticagrelor (OR 0.66, 95% CI: 0.49-0.90). Both prasugrel and ticagrelor reduced ST as compared to clopidogrel and aspirin for 12 months. CONCLUSIONS: Different DAPT strategies yield similar risk of MACE, major bleeding, death and stroke in ACS patients. Prasugrel and aspirin for 12 months proved to be the most effective strategy regarding ST and MI.

RESUMO

BACKGROUND: The aim of the present analysis was to evaluate the incidence and predictors of in-hospital adverse outcomes in nonagenarian patients undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI). METHODS: Consecutive nonagenarian patients undergoing pPCI for STEMI from 2009 to 2019 were retrospectively included in an international multicenter registry. In-hospital all-cause death was the primary outcome. RESULTS: A total of 308 patients were included (mean age 92.5±2.5 years, 65.6% female). Mean systolic blood pressure (SBP) at hospital admission was 130.7±33.5 mmHg, 46 (17%) patients presented with a Killip class III-IV, mean left ventricle ejection fraction (LVEF) was 40.0±11.5% and 147 (58%) patients were independent in everyday activities. In-hospital death occurred in 99 patients (32%). After multivariate adjustment, lower LVEF (OR per unit reduction 1.08, 95% CI: 1.03-1.11, P value <0.001), lower SBP (OR 1.02 per mmHg reduction, 95% CI: 1.01-1.03, P value 0.001) and being not independent at home (OR 2.56, 95% CI: 1.25-5.26, P value 0.01) resulted independent predictors of in-hospital mortality. A sensitivity analysis performed in final TIMI 3 flow population confirmed the prognostic role of LVEF and independency on in-hospital mortality. CONCLUSIONS: Nonagenarian patients presenting with STEMI and undergoing pPCI have high in-hospital mortality. Independency in everyday life is a strong independent predictor of survival to hospital discharge.
