RESUMO
ABSTRACT: The dual pathway inhibition (DPI) with low-dose rivaroxaban and aspirin in patients with stable atherosclerotic vascular disease reduces the occurrence of cardiovascular events, with no significant increase of intracranial or other critical organ bleedings. Our observational study aimed to describe the clinical performance, adherence, and persistence of DPI therapy among a real-world setting of patients with an established diagnosis of coronary artery (CAD) and/or peripheral artery disease (PAD). We prospectively included all consecutive patients with an established diagnosis of CAD and/or PAD treated with aspirin (ASA) 100 mg once daily and rivaroxaban 2.5 mg twice daily. Clinical evaluation was performed at baseline, before starting treatment, at 1 month, and every 6 months after the study drug administration. A total of 202 consecutive patients (mean age 66 ± 10 years; male 80%) eligible to DPI therapy were included. During a mean follow-up of 664 ± 177 days, the incidence rate of major bleedings and of major adverse cardiovascular events was 0.8 and 1.1 per 100 patients/year, respectively. The adherence to pharmacological treatment was 99%. Additionally, 13.4% of patients suspended the DPI therapy during the follow-up. Minor bleedings resulted the most common cause of both temporary and permanent DPI therapy discontinuation. This observational study supports the safety of DPI with low-dose rivaroxaban and aspirin among patients with CAD and PAD in a real-world setting, showing high persistence and maximum adherence to medical treatment.

BACKGROUND: The prognostic impact of functionally significant coronary artery disease, as assessed with quantitative flow ratio (QFR), in patients with severe aortic stenosis treated with transcatheter aortic valve replacement is unknown. METHODS: This is a retrospective study with blind analysis of angiographic data, enrolling consecutive patients with severe aortic stenosis treated with transcatheter aortic valve replacement at 4 Italian centers. None of the patients enrolled received pre-transcatheter aortic valve replacement or concomitant coronary revascularization, either for the absence of significant coronary stenoses or by clinical decision. Visual estimation of diameter stenosis and QFR analysis were performed in all coronary arteries. The end point was all-cause mortality at a 3-year follow-up. RESULTS: A total of 318 patients were enrolled. At visual estimation, 140 patients (44%) presented a diameter stenosis ≥50% in at least 1 coronary artery, whereas 78 patients (24.5%) had at least 1 vessel with QFR <0.80 and, therefore, included in the positive QFR group. Overall, 69 (21.7%) patients died during the follow-up. In the Kaplan-Meier analysis, patients with positive QFR experienced significantly higher rates of death during follow-up compared with those without (51.1% versus 12.1%; P<0.001), whereas no significant difference was evident in terms of death between patients with or without significant coronary artery disease according to angiographic evaluation (24.3% versus 19.7%; P=0.244). In a multivariate regression model, positive QFR was an independent predictor of all-cause death during follow-up (hazard ratio, 5.31 [95% CI, 3.21-8.76]). CONCLUSIONS: Coronary QFR can predict mortality in patients with severe aortic stenosis treated with transcatheter aortic valve replacement without revascularization.

To evaluate if integrating platelet reactivity (PR) evaluation in the original age, creatinine and ejection fraction (ACEF) score could improve the diagnostic accuracy of the model in patients with stable coronary artery disease (CAD). We enrolled patients treated with percutaneous coronary intervention between 2010 and 2011. High PR was included in the model (PR-ACEF). Co-primary end points were a composite of death/myocardial infarction (MI) and major adverse cardiovascular events (MACE). Overall, 471 patients were enrolled. Compared to the ACEF score, the PR-ACEF showed an improved diagnostic accuracy for death/MI (AUC 0.610 vs 0.670, p < 0.001) and MACE (AUC 0.572 vs 0.634, p < 0.001). These findings were confirmed using internal validation with bootstrap resampling. At 5 years, the PR-ACEF value > 1.75 was independently associated with death/MI [HR 3.51, 95% CI (1.97-6.23)] and MACE [HR 2.77, 95% CI (1.69-4.53)]. The PR-ACEF score was effective in improving the diagnostic performance of the ACEF score at the long-term follow-up.
RESUMO
BACKGROUND: The role of quantitative flow ratio (QFR) in the treatment of nonculprit vessels of patients with myocardial infarction (MI) is a topic of ongoing discussion. OBJECTIVES: This study aimed to investigate the predictive capability of QFR for adverse events and its noninferiority compared to wire-based functional assessment in nonculprit vessels of MI patients. METHODS: The FIRE (Functional Assessment in Elderly MI Patients With Multivessel Disease) trial randomized 1,445 older MI patients to culprit-only (n = 725) or physiology-guided complete revascularization (n = 720). In the culprit-only arm, angiographic projections of nonculprit vessels were prospectively collected, centrally reviewed for QFR computation, and associated with endpoints. In the complete revascularization arm, endpoints were compared between nonculprit vessels investigated with QFR or wire-based functional assessment. The primary endpoint was the vessel-oriented composite endpoint (VOCE) at 1 year. RESULTS: QFR was measured on 903 nonculprit vessels from 685 patients in the culprit-only arm. Overall, 366 (40.5%) nonculprit vessels showed a QFR value ≤0.80, with a significantly higher incidence of VOCEs (22.1% vs 7.1%; P < 0.001). QFR ≤0.80 emerged as an independent predictor of VOCEs (HR: 2.79; 95% CI: 1.64-4.75). In the complete arm, QFR was used in 320 (35.2%) nonculprit vessels to guide revascularization. When compared with propensity-matched nonculprit vessels in which treatment was guided by wire-based functional assessment, no significant difference was observed (HR: 0.57; 95% CI: 0.28-1.15) in VOCEs. CONCLUSIONS: This prespecified subanalysis of the FIRE trial provides evidence supporting the safety and efficacy of QFR-guided interventions for the treatment of nonculprit vessels in MI patients.

Importance: Patients with high bleeding risk (HBR) have a poor prognosis, and it is not known if they may benefit from complete revascularization after myocardial infarction (MI). Objective: To investigate the benefit of physiology-guided complete revascularization vs a culprit-only strategy in patients with HBR, MI, and multivessel disease. Design, Setting, and Participants: This was a prespecified analysis of the Functional Assessment in Elderly MI Patients With Multivessel Disease (FIRE) randomized clinical trial data. FIRE was an investigator-initiated, open-label, multicenter trial. Patients 75 years or older with MI and multivessel disease were enrolled at 34 European centers from July 2019 through October 2021. Physiology treatment was performed either by angiography- or wire-based assessment. Patients were divided into HBR or non-HBR categories in accordance with the Academic Research Consortium HBR document. Interventions: Patients were randomized to either physiology-guided complete revascularization or culprit-only strategy. Main Outcomes and Measures: The primary outcome comprised a composite of death, MI, stroke, or revascularization at 1 year. Secondary outcomes included a composite of cardiovascular death or MI and Bleeding Academic Research Consortium (BARC) types 3 to 5. Results: Among 1445 patients (mean [SD] age, 81 [5] years; 917 male [63%]), 1025 (71%) met HBR criteria. Patients with HBR were at higher risk for the primary end point (hazard ratio [HR], 2.01; 95% CI, 1.47-2.76), cardiovascular death or MI (HR, 1.89; 95% CI, 1.26-2.83), and BARC types 3 to 5 (HR, 3.28; 95% CI, 1.40-7.64). The primary end point was significantly reduced with physiology-guided complete revascularization as compared with culprit-only strategy in patients with HBR (HR, 0.73; 95% CI, 0.55-0.96). No indication of interaction was noted between revascularization strategy and HBR status for primary and secondary end points. Conclusions and Relevance: HBR status is prevalent among older patients with MI, significantly increasing the likelihood of adverse events. Physiology-guided complete revascularization emerges as an effective strategy, in comparison with culprit-only revascularization, for mitigating ischemic adverse events, including cardiovascular death and MI. Trial Registration: ClinicalTrials.gov Identifier: NCT03772743.

AIMS: The present analysis from the Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial aims to explore the significance of pre-admission physical activity and assess whether the benefits of physiology-guided complete revascularization apply consistently to sedentary and active older patients. METHODS AND RESULTS: Patients aged 75 years or more with myocardial infarction (MI) and multivessel disease were randomized to receive physiology-guided complete revascularization or culprit-only strategy. The primary outcome was a composite of death, MI, stroke, or any revascularization within a year. Secondary endpoints included the composite of cardiovascular death or MI, as well as single components of the primary endpoint. Pre-admission physical activity was categorized into three groups: (i) absent (sedentary), (ii) light, and (iii) vigorous. Among 1445 patients, 692 (48%) were sedentary, whereas 560 (39%) and 193 (13%) performed light and vigorous physical activity, respectively. Patients engaging in light or vigorous pre-admission physical activity exhibited a reduced risk of the primary outcome compared with sedentary individuals [light hazard ratio (HR) 0.70, 95% confidence interval (CI) 0.55-0.91 and vigorous HR 0.14, 95% CI 0.07-0.91, respectively]. These trends were also observed for death, cardiovascular death, or MI. When comparing physiology-guided complete revascularization vs. culprit-only strategy, no significant interaction was observed for primary and secondary endpoints when stratified by sedentary or active status. CONCLUSION: In older patients with MI, pre-admission physical activity emerges as a robust and independent prognostic determinant. Physiology-guided complete revascularization stands out an effective strategy in reducing ischaemic adverse events, irrespective of pre-admission physical activity status. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT03772743.
The Functional Assessment in Elderly Myocardial Infarction Patients with Multivessel Disease (FIRE) trial has shown that physiology-guided complete revascularization reduces ischaemic adverse events in older patients with myocardial infarction (MI) and multivessel disease. Older patients who engage in light or vigorous physical activity before hospitalization for MI have a reduced risk of the primary composite outcome of death, MI, stroke, or ischaemia-driven revascularization. These benefits extend to all secondary cardiovascular outcomes as well. In the present subanalysis of the FIRE trial, we find that the positive prognosis associated with physiology-guided complete revascularization holds true even for patients with a sedentary lifestyle. This means that this type of revascularization can effectively reduce ischaemic adverse events in older patients with MI and multivessel disease, regardless of their physical activity levels.
RESUMO
BACKGROUND: The debate surrounding the efficacy of coronary physiological guidance compared with conventional angiography in achieving optimal post-percutaneous coronary intervention (PCI) fractional flow reserve (FFR) values persists. OBJECTIVES: The primary aim of this study was to demonstrate the superiority of physiology-guided PCI, using either angiography or microcatheter-derived FFR, over conventional angiography-based PCI in complex high-risk indicated procedures (CHIPs). The secondary aim was to establish the noninferiority of angiography-derived FFR guidance compared with microcatheter-derived FFR guidance. METHODS: Patients with obstructive coronary lesions and meeting CHIP criteria were randomized 2:1 to receive undergo physiology- or angiography-based PCI. Those assigned to the former were randomly allocated to angiography- or microcatheter-derived FFR guidance. CHIP criteria were long lesion (>28 mm), tandem lesions, severe calcifications, severe tortuosity, true bifurcation, in-stent restenosis, and left main stem disease. The primary outcome was invasive post-PCI FFR value. The optimal post-PCI FFR value was defined as >0.86. RESULTS: A total of 305 patients (331 study vessels) were enrolled in the study (101 undergoing conventional angiography-based PCI and 204 physiology-based PCI). Optimal post-PCI FFR values were more frequent in the physiology-based PCI group compared with the conventional angiography-based PCI group (77% vs 54%; absolute difference 23%, relative difference 30%; P < 0.0001). The occurrence of the primary outcome did not differ between the 2 physiology-based PCI subgroups, demonstrating the noninferiority of angiography- vs microcatheter-derived FFR (P < 0.01). CONCLUSIONS: In CHIP patients, procedural planning and guidance on the basis of physiology (through either angiography- or microcatheter-derived FFR) are superior to conventional angiography for achieving optimal post-PCI FFR values.

Background: Coronary artery disease (CAD) is common in patients with aortic valve stenosis (AS) ranging from 60% to 80%. The clinical and prognostic role of coronary artery lesions in patients undergoing Transcatheter Aortic Valve Implantation (TAVI) remains unclear. The aim of the present observational study was to estimate long-term clinical outcomes by Quantitative Flow Ratio (QFR) characterization of CAD in a well-represented cohort of patients affected by severe AS treated by TAVI. Methods: A total of 439 invasive coronary angiographies of patients deemed eligible for TAVI by local Heart Teams with symptomatic severe AS were retrospectively screened for QFR analysis. The primary endpoint of the study was all-cause mortality. The secondary endpoint was a composite of cardiovascular mortality, stroke/transient ischemic attack (TIA), acute myocardial infarction (AMI), and any hospitalization after TAVI. Results: After exclusion of patients with no follow-up data, coronary angiography not feasible for QFR analysis and previous surgical myocardial revascularization (CABG) 48/239 (20.1%) patients had a QFR value lower or equal to 0.80 (QFR + value), while the remaining 191/239 (79.9%) did not present any vessel with a QFR positive value. In the adjusted Cox regression analysis, patients with positive QFR were independently associated with an increased risk of all-casual mortality (Model 1, HR 3.47, 95% CI, 2.35-5.12; Model 2, HR 5.01, 95% CI, 3.17-7.90). In the adjusted covariate analysis, QFR+ involving LAD (37/48, 77,1%) was associated with the higher risk of the composite outcome compared to patients without any positive value of QFR or non-LAD QFR positive value (11/48, 22.9%). Conclusions: Pre-TAVI QFR analysis can be used for a safe, simple, wireless functional assessment of CAD. QFR permits to identify patients at high risk of cardiovascular mortality or MACE, and it could be considered by local Heart Teams.
RESUMO
BACKGROUND: The benefit of complete revascularization in older patients (≥75 years of age) with myocardial infarction and multivessel disease remains unclear. METHODS: In this multicenter, randomized trial, we assigned older patients with myocardial infarction and multivessel disease who were undergoing percutaneous coronary intervention (PCI) of the culprit lesion to receive either physiology-guided complete revascularization of nonculprit lesions or to receive no further revascularization. Functionally significant nonculprit lesions were identified either by pressure wire or angiography. The primary outcome was a composite of death, myocardial infarction, stroke, or any revascularization at 1 year. The key secondary outcome was a composite of cardiovascular death or myocardial infarction. Safety was assessed as a composite of contrast-associated acute kidney injury, stroke, or bleeding. RESULTS: A total of 1445 patients underwent randomization (720 to receive complete revascularization and 725 to receive culprit-only revascularization). The median age of the patients was 80 years (interquartile range, 77 to 84); 528 patients (36.5%) were women, and 509 (35.2%) were admitted for ST-segment elevation myocardial infarction. A primary-outcome event occurred in 113 patients (15.7%) in the complete-revascularization group and in 152 patients (21.0%) in the culprit-only group (hazard ratio, 0.73; 95% confidence interval [CI], 0.57 to 0.93; P = 0.01). Cardiovascular death or myocardial infarction occurred in 64 patients (8.9%) in the complete-revascularization group and in 98 patients (13.5%) in the culprit-only group (hazard ratio, 0.64; 95% CI, 0.47 to 0.88). The safety outcome did not appear to differ between the groups (22.5% vs. 20.4%; P = 0.37). CONCLUSIONS: Among patients who were 75 years of age or older with myocardial infarction and multivessel disease, those who underwent physiology-guided complete revascularization had a lower risk of a composite of death, myocardial infarction, stroke, or ischemia-driven revascularization at 1 year than those who received culprit-lesion-only PCI.

OBJECTIVE: To compare the effects of ticagrelor and prasugrel on absolute coronary blood flow (Q) and microvascular resistance (R) in patients with stable coronary artery disease (CAD) treated with elective percutaneous coronary intervention (PCI) (NCT05643586). Besides being at least as effective as prasugrel in inhibiting platelet aggregation, ticagrelor has been shown to have additional properties potentially affecting coronary microcirculation. METHODS: We randomly assigned 50 patients to ticagrelor (180 mg) or prasugrel (60 mg) at least 12 hours before intervention. Continuous thermodilution was used to measure Q and R before and after PCI. Platelet reactivity was measured before PCI. Troponin I was measured before, 8 and 24 hours after PCI. RESULTS: At baseline, fractional flow reserve, Q and R were similar in two study groups. Patients in the ticagrelor group showed higher post-PCI Q (242±49 vs 205±53 mL/min, p=0.015) and lower R values (311 (263, 366) vs 362 (319, 382) mm Hg/L/min, p=0.032). Platelet reactivity showed a negative correlation with periprocedural variation of Q values (r=-0.582, p<0.001) and a positive correlation with periprocedural variation of R values (r=0.645, p<0.001). The periprocedural increase in high-sensitivity troponin I was significantly lower in the ticagrelor compared with the prasugrel group (5 (4, 9) ng/mL vs 14 (10, 24) ng/mL, p<0.001). CONCLUSIONS: In patients with stable CAD undergoing PCI, pretreatment with a loading dose of ticagrelor compared with prasugrel improves post-procedural coronary flow and microvascular function and seems to reduce the related myocardial injury.

BACKGROUND: Post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) values ≥0.90 are associated with a low incidence of adverse events. OBJECTIVES: The AQVA (Angio-based Quantitative Flow Ratio Virtual PCI Versus Conventional Angio-guided PCI in the Achievement of an Optimal Post-PCI QFR) trial aims to test whether a QFR-based virtual percutaneous coronary intervention (PCI) is superior to a conventional angiography-based PCI at obtaining optimal post-PCI QFR results. METHODS: The AQVA trial is an investigator-initiated, randomized, controlled, parallel-group clinical trial. A total of 300 patients (356 study vessels) undergoing PCI were randomized 1:1 to receive either QFR-based virtual PCI or angiography-based PCI (standard of care). The primary outcome was the rate of study vessels with a suboptimal post-PCI QFR value, which was defined as <0.90. Secondary outcomes were procedure duration, stent length/lesion, and stent number/patient. RESULTS: Overall, 38 (10.7%) study vessels missed the prespecified optimal post-PCI QFR target. The primary outcome occurred significantly more frequently in the angiography-based group (n = 26, 15.1%) compared with the QFR-based virtual PCI group (n = 12 [6.6%]; absolute difference = 8.5%; relative difference = 57%; P = 0.009). The main cause of a suboptimal result in the angiography-based group is the underestimation of a diseased segment outside the stented one. There were no significant differences among secondary endpoints, although stent length/lesion and stent number/patient were numerically lower in the virtual PCI group (P = 0.06 and P = 0.08, respectively), whereas procedure length was higher in the virtual PCI group (P = 0.06). CONCLUSIONS: The AQVA trial demonstrated the superiority of QFR-based virtual PCI over angiography-based PCI with regard to post-PCI optimal physiological results. Future larger randomized clinical trials that demonstrate the superiority of this approach in terms of clinical outcomes are warranted.

BACKGROUND: Studies investigating clinical outcomes of patients with or without endothelial disfunction (ED) treated with percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) using second generation drug eluting stents (DES) are lacking. METHODS: We prospectively collected data from 109 patients undergoing PCI with second generation DES due to stable CAD between December 2014 and September 2016. ED was evaluated evaluating the flow mediated dilation (FMD) at the brachial artery level and defined by an FMD < 7 %. Primary outcome were major adverse cardiovascular events (MACE), secondary outcomes were target vessel failure (TVR), myocardial infarction (MI) and all-cause death. RESULTS: Five-year follow-up was available in all patients. Median FMD didn't significantly differ between patients who experienced the outcome and those who didn't [no TVR vs. TVR: p = 0.358; no MI vs. MI: p = 0.157; no death vs. death: p = 0.355; no MACE vs. MACE: p = 0.805]. No association between ED and an increased risk for the primary outcome as well as for the secondary ones was evident [MACE: 17.0 % vs. 14.3 %, HR 0.87 (0.33-2.26), log rank p = 0.780; TVR: 9.4 % vs. 5.4 %, HR 0.53 (0.12-2.24), log rank p = 0.384; MI: 3.7 % vs. 8.9 %, HR 2.46 (0.47-12.76), log rank p = 0.265; death: 7.5 % vs. 3.6 %, HR 0.53 (0.09-2.90), log rank p = 0.458]. These findings were confirmed using a lower threshold of FMD to define ED and at one-year landmark analysis. CONCLUSIONS: ED is not associated with an increased risk of adverse events at long-term follow-up in a contemporary cohort of patients undergoing PCI with second generation DES.

BACKGROUND: The COVID-19 pandemic severely impacted global health. The aim of this study was to compare predictors of symptoms-to-emergency-call timing delay in acute coronary syndrome (ACS) and their impact on mortality before and during the COVID-19 outbreak. METHODS: We collected sociodemographic, clinical data, procedural features, preadmission and intra-hospital outcomes of consecutive patients admitted for ACS in seventeen Italian centers from March to April 2018, 2019, and 2020. RESULTS: In 2020, a 32.92% reduction in ACS admissions was observed compared to 2018 and 2019. Unstable angina, typical and atypical symptoms, and intermittent angina were identified as significant predictors of symptoms-to-emergency-call timing delay before and during the COVID-19 pandemic (P<0.005 for all the items). Differently from 2018-2019, during the pandemic, hypertension and dyspnea (P=0.002 versus P=0.490 and P=0.001 vs. P=0.761 for 2018-2019 and 2020, respectively) did not result as predictors of delay in symptoms-to-emergency-call timing. Among these predictors, only the atypical symptoms (HR 3.36; 95% CI: 1.172-9.667, P=0.024) in 2020 and the dyspnea (HR 2.64; 95% CI: 1.345-5.190, P=0.005) in 2018-2019 resulted significantly associated with higher mortality. Finally, the family attendance at the onset of the symptoms resulted in a reduction in symptoms-to-emergency-call timing (in 2020 P<0.001; CI: -1710.73; -493.19) and in a trend of reduced mortality (HR 0.31; 95% CI: 0.089-1.079, P=0.066) in 2020. CONCLUSIONS: During the COVID-19 outbreak, atypical symptoms and family attendance at ACS onset were identified, respectively, as adverse and favorable predictors of symptoms-to-emergency-call timing delay and mortality.

BACKGROUND: The COVID-19 pandemic increased the complexity of the clinical management and pharmacological treatment of patients presenting with an Acute Coronary Syndrome (ACS). AIM: to explore the incidence and prognostic impact of in-hospital bleeding in patients presenting with ACS before and during the COVID-19 pandemic. METHODS: We evaluated in-hospital Thrombolysis In Myocardial Infarction (TIMI) major and minor bleeding among 2851 patients with ACS from 17 Italian centers during the first wave of the COVID-19 pandemic (i.e., March-April 2020) and in the same period in the previous two years. RESULTS: The incidence of in-hospital TIMI major and minor bleeding was similar before and during the COVID-19 pandemic. TIMI major or minor bleeding was associated with a significant threefold increase in all-cause mortality, with a similar prognostic impact before and during the COVID-19 pandemic. CONCLUSIONS: the incidence and clinical impact of in-hospital bleeding in ACS patients was similar before and during the COVID-19 pandemic. We confirmed a significant and sizable negative prognostic impact of in-hospital bleeding in ACS patients.
RESUMO
Percutaneous coronary intervention (PCI) is frequently complicated by type 4a myocardial infarction (MI), which is associated with an increased risk of mortality. We assessed the usefulness of the angiography-derived hemodynamic index (ADDED), which is based on the extent of myocardium at risk and on the anatomical lesion severity, in predicting type 4a MI in patients with chronic coronary syndrome (CCS) undergoing PCI. We enrolled 442 patients treated with single-vessel PCI. The ADDED index was calculated as the ratio of the Duke Jeopardy Score to the minimum lumen diameter assessed with quantitative angiography analysis. Type 4a MI was defined according to the 4th Universal Definition of MI. The overall population was divided into tertiles of ADDED index. Type 4a MI occurred in 5 patients (3.3%) in the ADDED-low tertile, 8 (5.5%) in the ADDED-mid tertile, and 26 (17.7%) in the ADDED-high tertile (p < 0.0001). At ROC curve analysis, the ADDED index could significantly discriminate between patients with and without type 4a MI (area under the curve 0.745). At multivariate analysis, an ADDED index value > 5.25 was the strongest independent predictor type 4a MI. Our results support the role of the ADDED index as a predictor of type 4a MI in patients with CCS treated with elective PCI of a single vessel. Whether a selective use of additional preventive measures in patients considered at high risk based on ADDED index values may improve peri-procedural and long-term outcomes remains to be tested in dedicated investigations.

AIMS: To investigate the levels of platelet reactivity and the impact of high platelet reactivity (HPR) on long-term clinical outcomes of complex higher-risk and indicated patients (CHIP) with stable coronary artery disease (CAD) treated with elective percutaneous coronary intervention (PCI). METHODS: We enrolled 500 patients undergoing elective PCI for stable CAD and treated with aspirin and clopidogrel. Patients were divided into four groups based on the presence of CHIP features and HPR. Primary endpoint was the occurrence of major adverse clinical events (MACE) at 5âyears. RESULTS: The prevalence of HPR was significantly greater in the CHIP population rather than non-CHIP patients (39.9% vs 29.8%, Pâ=â0.021). Patients with both CHIP features and HPR showed the highest estimates of MACE (22.1%, log-rank Pâ=â0.047). At Cox proportional hazard analysis, the combination of CHIP features and HPR was an independent predictor of MACE (hazard ratio 2.57, 95% confidence interval 1.30-5.05, Pâ=â0.006). CONCLUSION: Among patients with stable CAD undergoing elective PCI and treated with aspirin and clopidogrel, the combination of CHIP features and HPR identifies a cohort of patients with the highest risk of MACE at 5âyears, who might benefit from more potent antiplatelet strategies.

PURPOSE: Wire-based coronary physiology pullback performed before percutaneous coronary intervention (PCI) discriminates coronary artery disease (CAD) distribution and extent, and is able to predict functional PCI result. No research investigated if quantitative flow ratio (QFR)-based physiology assessment is able to provide similar information. METHODS: In 111 patients (120 vessels) treated with PCI, QFR was measured both before and after PCI. Pre-PCI QFR trace was used to discriminate functional patterns of CAD (focal, serial lesions, diffuse disease, combination). Functional CAD patterns were identified analyzing changes in the QFR virtual pullback trace (qualitative method) or after computation of the QFR virtual pullback index (QVPindex) (quantitative method). QVPindex calculation was based on the maximal QFR drop over 20 mm and the length of epicardial coronary segment with QFR most relevant drop. Then, the ability of the different functional patterns of CAD to predict post-PCI QFR value was tested. RESULTS: By qualitative method, 51 (43%), 20 (17%), 15 (12%), and 34 (28%) vessels were classified as focal, serial focal lesions, diffuse disease, and combination, respectively. QVPindex values >0.71 and ≤0.51 predicted focal and diffuse patterns, respectively. Suboptimal PCI result (post-PCI QFR value ≤0.89) was present in 22 (18%) vessels. Its occurrence differed across functional patterns of CAD (focal 8% vs. serial lesions 15% vs. diffuse disease 33% vs. combination 29%, p=0.03). Similarly, QVPindex was correlated with post-PCI QFR value (r=0.62, 95% CI 0.50-0.72). CONCLUSION: Our results suggest that functional patterns of CAD based on pre-PCI QFR trace can predict the functional outcome after PCI.

AIMS: Adherence to medical therapy following acute coronary syndrome (ACS) affects a patient's prognosis. In this cohort study, we sought to assess the factors that could affect a patient's adherence to therapy after ACS. METHODS: We prospectively collected information from patients (Nâ=â964) hospitalized at the coronary care unit of the Federico II University Hospital, from 1 January 2015 to 30 June 2017, for ACS. Adherence to three classes of drugs including statins, antiplatelets [dual or single antiplatelet agent (SAPT)] and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARB) and their composites were assessed at 1âmonth, 1 and 2âyears after discharge. RESULTS: At 30âdays adherence to prescribed therapy was 94.4% for dual antiplatelet therapy (DAPT), 78.2% for statins, 92.7% for ACE-I/ARB and 70.7% for multitherapy. At 1 year, it was 91.1% for DAPT, 81.2% for ACE-I/ARB, 84.9% for statins and 71.4% for multitherapy. At 2 years, it was 97.1% for SAPT, 78.1% for ACE-I/ARB, 91.8% for statins, 72.8% for multitherapy. Multivariable logistic analysis demonstrated that at each time point, a telephone follow-up assessment predicts nonadherence to multitherapy and that a percutaneous coronary intervention at the index hospitalization is an independent predictor of adherence to composite therapy at 1âmonth and 1âyear. CONCLUSION: Up to 2 years after ACS, three out of four patients are adherent to multitherapy prescription; percutaneous coronary intervention during the index hospitalization improves a patient's adherence, whereas telephone follow-up is associated with reduced adherence to multitherapy.Campania Salute Network Registry (Clinical Trials.gov Identifier: NCT02211365).

We investigated the interaction between chronic kidney disease (CKD) and high platelet reactivity (HPR) in determining long-term clinical outcomes following elective PCI for stable coronary artery disease (CAD). A total of 500 patients treated with aspirin and clopidogrel were divided based on the presence of CKD (defined as glomerular filtration rate of < 60 ml/min/1.73 m2) and HPR (defined as a P2Y12 reaction unit value ≥ 240 at VerifyNow assay). Primary endpoint was the occurrence of major adverse clinical events (MACE) at 5 years. Patients with both CKD and HPR showed the highest estimates of MACE (25.6%, p = 0.005), all-cause death (17.9%, p = 0.004), and cardiac death (7.7%, p = 0.004). The combination of CKD and HPR was an independent predictor of MACE (HR 3.12, 95% CI 1.46-6.68, p = 0.003). In conclusion, the combination of CKD and HPR identifies a cohort of patients with the highest risk of MACE at 5 years.

We evaluated the predictive power of age, creatinine, and ejection fraction (ACEF) score on mortality at 5-year follow-up in a population of 471 patients with chronic coronary syndrome (CCS) treated with percutaneous coronary intervention (PCI). Patients in the ACEF-High tertile showed the highest incidence of death at 5 years (15.7% vs. 2.6% in ACEF-Low and 4.3% in ACEF-Mid; log rank p<0.001). The ACEF score could significantly discriminate between patients who died and those who were still alive at 5 years (AUC 0.741, 95% CI 0.654-0.828), and an ACEF score >1.32 was identified as the optimal cutoff point to predict 5-year mortality (sensitivity 74%, specificity 68%). An ACEF score >1.32 was an independent predictor of 5-year mortality (HR 5.77, 95% CI 2.70-12.31; p<0.001). Our study shows that the ACEF score can predict mortality at 5-year follow-up in patients with CCS treated with PCI.
