RESUMO

AIMS: Patients with chronic kidney disease (CKD) are at increased risk of cardiovascular disease and have a worse prognosis after percutaneous coronary interventions (PCI). The BioFreedom polymer-free biolimus-A9-eluting stent (PF-BES) has shown promising results in patients at high bleeding risk; however, its performance in CKD patients has yet to be analyzed. METHODS: The all-comers RUDI-FREE registry documented patients undergoing PCI with PF-BES in routine clinical practice. Patients were stratified into three groups according to their estimated glomerular filtration rate (eGFR): preserved renal function, mild renal insufficiency (RI), and with moderate to severe RI (eGFR ≥ 90, between 90 and 45, and <45 ml/min/1.73 m2, respectively). The primary safety end point was a patient-oriented composite end point of cardiovascular death, myocardial infarction (MI), and definite or probable stent thrombosis (ST). The primary efficacy end point was target lesion revascularization (TLR). RESULTS: The registry documented 1,104 consecutive patients treated with PF-BES: 258 (23.4%) with preserved renal function, whereas 712 (64.7%) and 131 (11.9%) had mild and moderate to severe RI, respectively. At 1 year, the primary safety end point was significantly higher in patients with moderate to severe RI (3.5% vs. 2.8% vs. 11.5%; P < 0.001). Conversely, TLR proved similar among groups (0.4% vs. 1.8% vs. 0.8%; P = 0.235). CONCLUSIONS: Patients with worse renal function had increased risk of the composite of cardiovascular deaths, MI, and definite or probable ST. However, the PF-BES showed similar efficacy despite differences in renal function. These findings need to be confirmed in large-scale randomized trials.

RESUMO

Contemporary evidence supports device-based transcatheter interventions for the management of patients with structural heart disease. These procedures, which include aortic valve implantation, mitral or tricuspid valve repair/implantation, left atrial appendage occlusion, and patent foramen ovale closure, profoundly differ with respect to clinical indications and procedural aspects. Yet, patients undergoing transcatheter cardiac interventions require antithrombotic therapy before, during, or after the procedure to prevent thromboembolic events. However, these therapies are associated with an increased risk of bleeding complications. To date, challenges and controversies exist regarding balancing the risk of thrombotic and bleeding complications in these patients such that the optimal antithrombotic regimens to adopt in each specific procedure is still unclear. In this review, we summarize current evidence on antithrombotic therapies for device-based transcatheter interventions targeting structural heart disease and emphasize the importance of a tailored approach in these patients.

RESUMO

Sodium-glucose cotransporter 2 inhibitors (SGLT2i), initially born as anti-diabetic drugs, have shown many beneficial effects on the cardiovascular system, in particular against heart failure (HF). HF is a complex and multifaceted disease that requires a comprehensive approach. It should not be considered as a simplistic cardiac disease, but a systemic disease that leads to multisystemic organ failure and death. Exploiting their pleiotropic effects, SGLT2i are a very valid tool for HF treatment. Beyond the indication to reduce HF hospitalization and death risk, in patients with diabetes mellitus at high cardiovascular risk or with established cardiovascular event, SGLT2i administration reported beneficial effects regarding the wide spectrum of HF manifestations and stages, independently by diabetes mellitus presence. Recent evidence focuses on HF rehospitalization, cardiac and all-cause death reduction, as well as symptoms and quality of life improvement, in patients with chronic HF or with a recent HF decompensation episode. Given the recent finding about the SGLT2i usefulness in HF patients, further studies are needed to define the best administration timing to maximize the SGLT2i-derived beneficial effects.

RESUMO

BACKGROUND: Advanced heart failure (HF) is a condition often requiring elevated doses of loop diuretics. Therefore, these patients often experience poor diuretic response. Both conditions have a detrimental impact on prognosis and hospitalization. AIMS: This retrospective, multicenter study evaluates the effect of the addition of oral metolazone on diuretic response (DR), clinical congestion, NTproBNP values, and renal function over hospitalization phase. Follow-up analysis for a 6-month follow-up period was performed. METHODS: We enrolled 132 patients with acute decompensated heart failure (ADHF) in advanced NYHA class with reduced ejection fraction (EF < 40%) taking a mean furosemide amount of 250 ± 120 mg/day. Sixty-five patients received traditional loop diuretic treatment plus metolazone (Group M). The mean dose ranged from 7.5 to 15 mg for one week. Sixty-seven patients continued the furosemide (Group F). Congestion score was evaluated according to the ESC recommendations. DR was assessed by the formula diuresis/40 mg of furosemide. RESULTS: Patients in Group M and patients in Group F showed a similar prevalence of baseline clinical congestion (3.1 ± 0.7 in Group F vs. 3 ± 0.8 in Group M) and chronic kidney disease (CKD) (51% in Group M vs. 57% in Group F; p = 0.38). Patients in Group M experienced a better congestion score at discharge compared to patients in Group F (C score: 1 ± 1 in Group M vs. 3 ± 1 in Group F p > 0.05). Clinical congestion resolution was also associated with weight reduction (-6 ± 2 in Group M vs. -3 ± 1 kg in Group F, p < 0.05). Better DR response was observed in Group M compared to F (940 ± 149 mL/40 mgFUROSEMIDE/die vs. 541 ± 314 mL/40 mgFUROSEMIDE/die; p < 0.01), whereas median ΔNTproBNP remained similar between the two groups (-4819 ± 8718 in Group M vs. -3954 ± 5560 pg/mL in Group F NS). These data were associated with better daily diuresis during hospitalization in Group M (2820 ± 900 vs. 2050 ± 1120 mL p < 0.05). No differences were found in terms of WRF development and electrolyte unbalance at discharge, although Group M had a significant saline solution administration during hospitalization. Follow-up analysis did not differ between the group but a reduced trend for recurrent hospitalization was observed in the M group (26% vs. 38%). CONCLUSIONS: Metolazone administration could be helpful in patients taking an elevated loop diuretics dose. Use of thiazide therapy is associated with better decongestion and DR. Current findings could suggest positive insights due to the reduced amount of loop diuretics in patients with advanced HF.

RESUMO

Background: IHD is determined by an inadequate coronary blood supply to the myocardium, and endothelial dysfunction may represent one of the main pathophysiological mechanisms involved. Genetic predisposition to endothelial dysfunction has been associated with IHD and its clinical manifestation. However, studies are often confounding and inconclusive for several reasons, such as interethnic differences. Validation of results in larger cohorts and new populations is needed. The aim of this study is to evaluate the associations between the allelic variants of the eNOS rs1799983 single-nucleotide polymorphism, IHD susceptibility and its clinical presentation. Methods: A total of 362 consecutive patients with suspected myocardial ischemia were enrolled. Patients were divided into three groups: G1, coronary artery disease (CAD); G2, coronary microvascular dysfunction (CMD); and G3, a control group with anatomically and functionally normal coronary arteries. Analysis of three allelic variants, GT, GG and TT, of rs1799983 for the NOS3 gene, encoding for eNOS, was performed. Results: rs1799983_GT was significantly more expressed by the ischemic groups (G1 and G2) compared to G3. The TT variant was significantly more expressed by the G1 group, compared to the G2 group. Among ischemic patients, GT was significantly more expressed in patients with acute coronary syndrome (ACS) presentation, compared to other clinical presentations. In the multivariate analysis, the allelic variant GT was found to potentially represent an independent predictor of IHD and ACS presentation. Conclusion: The presence of the SNP rs1799983_GT, encoding for eNOS, is an independent risk factor for IHD and, remarkably, for ACS presentation, independently of cardiovascular risk factors. These results may be useful for the prediction of IHD development, particularly with an acute clinical manifestation. They may allow the early identification of patients at high risk of developing IHD with an ACS, promoting a genetic-based prevention strategy against IHD.

RESUMO

BACKGROUND: There is lack of evidence regarding the screening role of ECG for sudden cardiac death (SCD) prevention. OBJECTIVE: To evaluate the prevalence of ECG abnormalities among teenagers according to sport participation and competitive status. METHODS: Eleven thousand nine hundred and forty-nine Italian pupils from 179 secondary schools (13-19 years) were consecutively enrolled. ECG abnormalities were divided into minor and major. Medical history, clinical examination and sport activity information were acquired. Further evaluations were suggested in case of major ECG abnormalities. Follow-up was performed at 2 years. RESULTS: N = 1945 (16%) pupils had ECG abnormalities. Major ECG abnormalities were detected in 13% of the cohort, minor in 34%. ECG abnormalities were more common in nonathletes compared with athletes. A diagnosis of cardiac disease was reached in 25 (1.6%) of the pupils with major ECG abnormalities. CONCLUSION: ECG abnormalities are common among young populations and more prevalent in nonathletes. Among pupils with major ECG abnormalities 1.6% had a cardiac disease diagnosis. Our results are in line with the data supporting ECG screening in the general young population.

RESUMO

BACKGROUND: The significant interaction between major infection and 5-year mortality after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) for complex coronary artery disease (CAD) was observed previously. However, the very long-term outcomes beyond 5 years remains unclear. METHODS AND RESULTS: This is a subgroup analysis of the SYNTAX Extended Survival (SYNTAXES) trial, which is the extended follow-up of the randomized SYNTAX trial comparing PCI versus CABG in patients with three-vessel disease (3VD) or left-main CAD (LMCAD). Out of 1517 patients enrolled in the SYNTAX trial with available survival status from 5 to 10 years, 140 patients had experienced major infections and survived at 5 years (major infection group). From 5 to 10 years, the mortality of major infection group was 19.8% whereas the mortality of no major infection group was 15.1% (p = 0.157). After the adjustment of other clinical factors, the risk of mortality from 5 to 10 years did not significantly differ between major infection and no major infection groups (HR: 1.10; 95% CI: 0.62-1.96; p = 0.740). When stratified by the presence or absence of periprocedural major infections, defined as a major infection within 60 days after index procedure, there was also no significant difference in 10-year mortality between two groups (30.8% vs. 24.5%; p = 0.057). CONCLUSIONS: Despite the initial association between major infections and 5 years mortality, postprocedural major infection was not evident in the 10 years follow-up, suggesting that the impact of major infection on mortality subsided over time beyond 5 years. TRIAL REGISTRATION: SYNTAXES ClinicalTrials.gov reference: NCT03417050 SYNTAX ClinicalTrials.gov reference: NCT00114972.

RESUMO

BACKGROUND: We previously reported that severe COVID-19 patients had higher chances of survival and a reduced risk of developing respiratory failure when administered with the probiotic formulation SLAB51. This study aimed to investigate further bacteriotherapy mechanisms and how early they are activated. METHODS: We performed an analysis on the blood oxygenation parameters collected in sixty-nine severe COVID-19 patients requiring non-invasive oxygen therapy and presenting a CT lung involvement ≥50%. Twenty-nine patients received low-molecular-weight heparin, azithromycin and Remdesivir. In addition, forty subjects received SLAB51. Blood gas analyses were performed before the beginning of treatments and at 24 h. RESULTS: The patients receiving only standard therapy needed significantly increased oxygen amounts during the 24 h observation period. Furthermore, they presented lower blood levels of pO2, O2Hb and SaO2 than the group also supplemented with oral bacteriotherapy. In vitro data suggest that SLAB51 can reduce nitric oxide synthesis in intestinal cells. CONCLUSIONS: SARS-CoV-2 infected patients may present lesions in the lungs compromising their gas exchange capability. The functionality of the organs essential for these patients' survival depends mainly on the levels of pO2, O2Hb and SaO2. SLAB51 contains enzymes that could reduce oxygen consumption in the intestine, making it available for the other organs.

RESUMO

BACKGROUND: Cardiovascular disease (CVD) can occur in COVID-19 and has impact on clinical course. Data on CVD prevalence in hospitalized COVID-19 patients and sequelae in survivors is limited. Aim of this prospective study carried out on consecutive unselected COVID-19 population, was to assess: 1) CVD occurrence among hospitalized COVID-19 patients, 2) persistence or new onset of CVD at one-month and one-year follow-up. METHODS: Over 30 days n = 152 COVID-19 patients underwent cardiovascular evaluation. Standard electrocardiogram (ECG), Troponin and echocardiography were integrated by further tests when indicated. Medical history, arterial blood gas, blood tests, chest computed tomography and treatment were recorded. CVD was defined as the occurrence of a new condition during the hospitalization for COVID-19. Survivors attended a one-month follow-up visit and a one-year telephone follow-up. RESULTS: Forty-two patients (28%) experienced a wide spectrum of CVD with acute myocarditis being the most frequent. Death occurred in 32 patients (21%) and more frequently in patients who developed CVD (p = 0.032). After adjustment for confounders, CVD was independently associated with death occurrence. At one-month follow-up visit, 7 patients (9%) presented persistent or delayed CVD. At one-year telephone follow-up, 57 patients (48%) reported persistent symptoms. CONCLUSION: Cardiovascular evaluation in COVID-19 patients is crucial since the occurrence of CVD in hospitalized COVID-19 patients is common (28%), requires specific treatment and increases the risk of in-hospital mortality. Persistence or delayed presentation of CVD at 1-month (9%) and persistent symptoms at 1-year follow-up (48%) suggest the need for monitoring COVID-19 survivors.

RESUMO

Long term survival and its determinants after Percutaneous Coronary Intervention (PCI) on Unprotected Left Main Coronary Artery (ULMCA) remain to be appraised. In 9 European Centers 470 consecutive patients performing PCI on ULMCA between 2002 and 2005 were retrospectively enrolled. Survival from all cause and cardiovascular (CV) death were the primary end points, while their predictors at multivariate analysis the secondary ones. Among the overall cohort 81.5% of patients were male and mean age was 66 ± 12 years. After 15 years (IQR 13 to 16), 223 patients (47%) died, 81 (17.2%) due to CV etiology. At multivariable analysis, older age (HR 1.06, 95%CI 1.02 to 1.11), LVEF < 35% (HR 2.97, 95%CI 1.24 to 7.15) and number of vessels treated during the index PCI (HR 1.75, 95%CI 1.12 to 2.72) were related to all-cause mortality, while only LVEF <35% (HR 4.71, 95%CI 1.90 to 11.66) to CV death. Repeated PCI on ULMCA occurred in 91 (28%) patients during the course of follow up and did not significantly impact on freedom from all-cause or CV mortality. In conclusion, in a large, unselected population treated with PCI on ULMCA, 47% died after 15 years, 17% due to CV causes. Age, number of vessels treated during index PCI and depressed LVEF increased risk of all cause death, while re-PCI on ULMCA did not impact survival.

RESUMO

Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome responsible for high mortality and morbidity rates. It has an ever growing social and economic impact and a deeper knowledge of molecular and pathophysiological basis is essential for the ideal management of HFpEF patients. The association between HFpEF and traditional cardiovascular risk factors is known. However, myocardial alterations, as well as pathophysiological mechanisms involved are not completely defined. Under the definition of HFpEF there is a wide spectrum of different myocardial structural alterations. Myocardial hypertrophy and fibrosis, coronary microvascular dysfunction, oxidative stress and inflammation are only some of the main pathological detectable processes. Furthermore, there is a lack of effective pharmacological targets to improve HFpEF patients' outcomes and risk factors control is the primary and unique approach to treat those patients. Myocardial tissue characterization, through invasive and non-invasive techniques, such as endomyocardial biopsy and cardiac magnetic resonance respectively, may represent the starting point to understand the genetic, molecular and pathophysiological mechanisms underlying this complex syndrome. The correlation between histopathological findings and imaging aspects may be the future challenge for the earlier and large-scale HFpEF diagnosis, in order to plan a specific and effective treatment able to modify the disease's natural course.

RESUMO

BACKGROUND: Early detection of myocardial involvement can be relevant in coronavirus disease 2019 (COVID-19) patients to timely target symptomatic treatment and decrease the occurrence of the cardiac sequelae of the infection. The aim of the present study was to assess the clinical value of cardiovascular magnetic resonance (CMR) in characterizing myocardial damage in active COVID-19 patients, through the correlation between qualitative and quantitative imaging biomarkers with clinical and laboratory evidence of myocardial injury. METHODS: In this retrospective observational cohort study, we enrolled 27 patients with diagnosis of active COVID-19 and suspected cardiac involvement, referred to our institution for CMR between March 2020 and January 2021. Clinical and laboratory characteristics, including high sensitivity troponin T (hs-cTnT), and CMR imaging data were obtained. Relationships between CMR parameters, clinical and laboratory findings were explored. Comparisons were made with age-, sex- and risk factor-matched control group of 27 individuals, including healthy controls and patients without other signs or history of myocardial disease, who underwent CMR examination between January 2020 and January 2021. RESULTS: The median (IQR) time interval between COVID-19 diagnosis and CMR examination was 20 (13.5-31.5) days. Hs-cTnT values were collected within 24 h prior to CMR and resulted abnormally increased in 18 patients (66.6%). A total of 20 cases (74%) presented tissue signal abnormalities, including increased myocardial native T1 (n = 11), myocardial T2 (n = 14) and extracellular volume fraction (ECV) (n = 10), late gadolinium enhancement (LGE) (n = 12) or pericardial enhancement (n = 2). A CMR diagnosis of myocarditis was established in 9 (33.3%), pericarditis in 2 (7.4%) and myocardial infarction with non-obstructive coronary arteries in 3 (11.11%) patients. T2 mapping values showed a moderate positive linear correlation with Hs-cTnT (r = 0.58; p = 0.002). A high degree positive linear correlation between ECV and Hs-cTnT was also found (r 0.77; p < 0.001). CONCLUSIONS: CMR allows in vivo recognition and characterization of myocardial damage in a cohort of selected COVID-19 individuals by means of a multiparametric scanning protocol including conventional imaging and T1-T2 mapping sequences. Abnormal T2 mapping was the most commonly abnormality observed in our cohort and positively correlated with hs-cTnT values, reflecting the predominant edematous changes characterizing the active phase of disease.

RESUMO

Patients with severely calcified coronary lesions undergoing percutaneous revascularization have a substantial risk of adverse outcomes, both during the procedure and in the long term. Over the last decade, a renewed interest has been observed about devices for plaque modification and lesion preparation, new technologies have been introduced in clinical practice and well-known devices have undergone technical and procedural improvements. The available tools for intravascular imaging allow a detailed evaluation of the calcific plaques within all the layers of the vessel wall. The complementary use of all these tools is ultimately aimed at optimizing the mechanics of balloon angioplasty and the delivery and expansion of drug-eluting stents. It has been fully demonstrated that rotational atherectomy improves procedural success when treating heavily calcified lesions. Intravascular lithotripsy, techniques and materials used during complex procedures such as chronic total occlusions, increasing operators' experience, as well as new drug-eluting stents with excellent mechanical characteristics, have further contributed to the feasibility and the safety of treating most fibrotic and heavily calcified vessels. We finally propose an algorithm for evaluation and treatment of severely calcific coronary lesions to demonstrate how such percutaneous revascularization procedures are planned and performed.

RESUMO

In over a year, the COVID-19 pandemic caused 2.69 million deaths and 122 million infections. Social isolation and distancing measures have been the only prevention available for months. Scientific research has done a great deal of work, developing in a few months safe and effective vaccines against COVID-19. In the European Union, nowadays, four vaccines have been authorized for use: Pfizer-BioNTech, Moderna, ChAdOx1 (AstraZeneca/Oxford), Janssen (Johnson & Johnson), and three others are currently under rolling review.Vaccine allocation policy is crucial to optimize the advantage of treatment preferring people with the highest risk of contagion. These days the priority in the vaccination program is of particular importance since it has become clear that the number of vaccines is not sufficient for the entire Italian population in the short term. Cardiovascular diseases are frequently associated with severe COVID-19 infections, leading to the worst prognosis. The elderly population suffering from cardiovascular diseases is, therefore, to be considered a particularly vulnerable population. However, age cannot be considered the only discriminating factor because in the young-adult population suffering from severe forms of heart disease, the prognosis, if affected by COVID-19, is particularly ominous and these patients should have priority access to the vaccination program. The aim of this position paper is to establish a consensus on a priority in the vaccination of COVID-19 among subjects suffering from different cardiovascular diseases.

RESUMO

COronaVIrus Disease-19 (COVID-19) had a huge impact on human health and economy. However, to this date, the effects of the pandemic on the training of young cardiologists are only partially known. To assess the consequences of the pandemic on the education of the cardiologists in training, we performed a 23-item national survey that has been delivered to 1443 Italian cardiologists in training, registered in the database of the Italian Society of Cardiology (SIC). Six hundred and thirty-three cardiologists in training participated in the survey. Ninety-five percent of the respondents affirmed that the training programme has been somewhat stopped or greatly jeopardized by the pandemic. For 61% of the fellows in training (FITs), the pandemic had a negative effect on their education. Moreover, 59% of the respondents believe that they would not be able to fill the gap gained during that period over the rest of their training. A negative impact on the psycho-physical well being has been reported by 86% of the FITs. The COVID-19 pandemic had an unparalleled impact on the education, formation and mental state of the cardiologists in training. Regulatory agencies, universities and politicians should make a great effort in the organization and reorganization of the teaching programs of the cardiologists of tomorrow.

RESUMO

BACKGROUND: Chronic pre-procedural and acute post-procedural myocardial injury are frequently observed in patients with aortic stenosis undergoing trans-catheter aortic valve implantation (TAVI). The aim of our study was to investigate the prognostic role of high sensitivity cardiac troponins (hs-cTns) elevation before and after TAVI. METHODS: 106 patients with severe aortic stenosis who underwent TAVI were enrolled. High sensitivity cardiac troponin T (hs-cTnT) was measured before and after TAVI (6, 24, 48, 72 hours). Post-procedural myocardial damage was defined as a 15-fold rise in hs-cTnT upper reference limit (URL) after TAVI. The clinical endpoints were all cause death, cardiovascular death and rehospitalization at 24 months follow-up. RESULTS: Before TAVI, hs-cTnT median value was 0.03 µg/L (2.3 ± 2.1 fold over URL). After TAVI procedure, myocardial damage (MD), as defined by VARC-2 criteria, was observed in 40 patients (38%) (MD group). In our population, logarithmically transformed hs-cTnTs were independently associated with all-cause mortality at 24 months F/U (pre-TAVI hs-cTnT: Hazard ratio [HR] 2.2, 95% confidence interval [CI]: 1.1 to 4.4, p=0.027). No significant differences were observed between the MD and non-MD groups for the three endpoints of all cause death (p log rank: 0.15), cardiovascular death (p log rank: 0.86) and re-hospitalization (p log rank: 0.87). CONCLUSIONS: Only baseline hs-cTnT levels correlated with outcomes at 24 months of follow-up. Chronic pre-procedural myocardial injury significantly affects prognosis after TAVI.

RESUMO

Given human immunodeficiency virus-1 (HIV-1)-infected patients have alterations in the type I interferon (IFN-I) pathway and are also at elevated risk of atherosclerosis, we evaluated IFN-I response and subclinical cardiovascular disease (CVD) association in HIV-1-infected patients. Transcript levels of IFN-α/ß and IFN-stimulated gene 56 (ISG56) were evaluated by RT/real-time PCR in peripheral blood mononuclear cells collected from asymptomatic HIV-1-positive male patients at high risk of developing CVD (n = 34) and healthy subjects (n = 21). Stenosis degree (≥ or <50%), calcium volume score, calcium Agatston score, and myocardial extracellular volume were examined by coronary computerized tomography scan. Carotid intima-media thickness (cIMT), Framingham risk score, atherosclerotic cardiovascular disease (ASCVD) score, and risk score developed by data collection on adverse effects of anti-HIV drugs (D:A:D) were also measured. Increased IFN-α, IFN-ß, and ISG56 levels were observed in all HIV-1-infected males compared to healthy controls (p < .001 for all genes analyzed). HIV-1-infected patients with a stenosis degree ≥50% showed a higher Framingham risk score (p = .019), which was correlated with IFN-ß and ISG56 levels. HIV-1-infected males with enhanced IFN-I levels and stenosis displayed a higher ASCVD calculated risk (p = .011) and D:A:D score (p = .004). Also, there was a trend toward higher IFN-α and ISG56 mRNA levels in HIV-1-positive patients with an increased cIMT (p > .05). Dysregulation of IFN-I response might participate in the pathogenesis of HIV-1-associated CVD.

RESUMO

BACKGROUND: A polymer-free biolimus-eluting stent (PF-BES) and a zotarolimus-eluting stent (ZES) recently showed similar clinical profiles and appear to be competing options in specific clinical settings of patients undergoing percutaneous coronary intervention (PCI). Whether they perform similarly also in complex procedural settings as coronary bifurcation lesions remains unaddressed. METHODS: All consecutive patients undergoing coronary bifurcation PCI with PF-BES or the new iteration of the ZES from three large multicenter real-world registries were included. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI), target lesion revascularization (TLR) and stent thrombosis (ST). Multiple analyses to adjust for baseline differences were carried out including propensity-score matching, propensity-score stratification and inverse-probability-weighting. Outcomes are reported according to Cox proportional hazard models censored at 400-day follow-up. RESULTS: 1169 patients treated with PF-BES (n = 440) or ZES (n = 729) on the main branch of a coronary bifurcation lesion were included (mean age 69 ± 11 years, 75.4% male, 53.8% acute coronary syndrome at presentation, 26.6% left main bifurcation, median dual antiplatelet therapy duration 12 [range 12-12] months). MACE, all-cause death, TLR and ST tended towards non-statistically higher rates with the PF-BES as compared to the ZES. Higher MI and target vessel revascularization occurrence was observed with PF-BES. CONCLUSIONS: In this large contemporary cohort of patients undergoing coronary bifurcation PCI, the occurrence of MACE was non-statistically different with the use of PF-BES and ZES devices. However, differences favoring the ZES device that may entail clinical relevance were observed. Further studies are needed to confirm these findings and explore whether they remain valid when a short dual antiplatelet therapy is adopted.
