RESUMEN

The mean age of patients with coronary artery disease (CAD) is steadily increasing. In older patients, there is a tendency to underutilize invasive approach, coronary revascularization, up-to-date pharmacological therapies, and secondary prevention strategies, including cardiac rehabilitation. Older adults with CAD commonly exhibit atypical symptoms, multi-vessel disease involvement, complex coronary anatomy, and a higher presence of risk factors and comorbidities. Although both invasive procedures and medical treatments are characterized by a higher risk of complications, avoidance may result in a suboptimal outcome. Often, overlooked factors, such as coronary microvascular disease, malnutrition, and poor physical performance, play a key role in determining prognosis, yet they are not routinely assessed or addressed in older patients. Historically, clinicians have relied on sub-analyses or observational findings to make clinical decisions, as older adults were frequently excluded or under-represented in clinical studies. Recently, dedicated evidence through randomized clinical trials has become available for older CAD patients. Nevertheless, the management of older CAD patients still raises several important questions. This review aims to comprehensively summarize and critically evaluate this emerging evidence, focusing on invasive management and coronary revascularization. Furthermore, it seeks to contextualize these interventions within the framework of improved risk stratification tools for older CAD patients, through user-friendly scales along with emphasizing the importance of promoting physical activity and exercise training to enhance the outcomes of invasive and medical treatments. This comprehensive approach may represent the key to improving prognosis in the complex and growing patient population of older CAD patients.

RESUMEN

BACKGROUND: The FIRE trial (Functional Assessment in Elderly Myocardial Infarction Patients With Multivessel Disease) enrolled 1445 older (aged ≥75 years) patients with myocardial infarction and multivessel disease in Italy, Spain, and Poland. Patients were randomized to physiology-guided complete revascularization or treatment of the only culprit lesion. Physiology-guided complete revascularization significantly reduced ischemic adverse events at 1 year. This prespecified analysis investigated the changes between the 2 study groups in angina status, quality of life, physical performance, and frailty. METHODS: Patients underwent validated scales at hospital discharge (baseline) and 1 year later. Angina status was evaluated using the Seattle Angina Questionnaire, health-related quality of life by EQ visual analog scale, physical performance by short physical performance battery, and frailty by the clinical frailty scale. Mixed models for repeated measures analysis were used to study the association between the treatment arms, time, and scales. RESULTS: Baseline and 1-year Seattle Angina Questionnaire, EQ visual analog scale, short physical performance battery, and clinical frailty scale were collected in around two-thirds of the entire FIRE study population. The mean age was 80.9±4.6 years (female sex, 35.9%). Overall, 35.3% were admitted for ST-segment-elevation myocardial infarction, whereas the others were admitted for non-ST-segment-elevation myocardial infarction. Physiology-guided complete revascularization, compared with culprit-only revascularization, was associated with greater improvement in terms of angina status (Seattle Angina Questionnaire summary score, 7.3 [95% CI, 6.1-8.6] points), health-related quality of life (EQ visual analog scale, 6.2 [95% CI, 4.4-8.1] points), and physical performance (short physical performance battery, 1.1 [95% CI, 0.9-1.3] points). After 1 year, patients randomized to culprit-only revascularization experienced a deterioration in frailty status (clinical frailty scale, 0.2 [95% CI, 0.1-0.3] points), which was not observed in patients randomized to physiology-guided complete revascularization. CONCLUSIONS: The present analysis suggested that a physiology-guided complete revascularization is associated with consistent benefits in terms of angina status, quality of life, physical performance, and the absence of further deterioration of the frailty status.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Use of Intra-Aortic Balloon Pump (IABP) in combination with Impella has been described as an alternative strategy for mechanical circulatory support (MCS) in patients with cardiogenic shock (CS). We provide a systematic review aimed to explore the effectiveness of this paired MCS approach. METHODS: We conducted a comprehensive systematic search in MEDLINE, Scopus, and Cochrane databases to identify all studies that investigated dual MCS with IABP and Impella. RESULTS: Our search strategy identified 12 articles, including 1 randomized controlled trial, 1 retrospective study, 1 case series, 7 case report and 2 animal studies. Rationale for this combined MCS strategy stems from an observed reduction in myocardial oxygen demand/supply ratio compared to the use of each device alone, without determining significant variations in left ventricular work. Nonetheless, this combined approach also leads to a 30-40 % decline in Impella flow, increasing the risk of bleeding, Impella displacement, as well as triggering positioning and pressure alarms. Additionally, hemolytic risk data yielded inconclusive results. Importantly, there were no notable disparities in mortality rates when comparing the combined strategy to the use of each device individually. CONCLUSION: At the current state-of-the-art, there are no conclusive data demonstrating net clinical benefits of combining Impella with IABP. Considering the substantial risks of morbidity associated, we recommend against its use in clinical practice.

RESUMEN

BACKGROUND: Diffuse coronary artery disease (CAD) impacts the safety and efficacy of percutaneous coronary intervention (PCI). Pathophysiological CAD patterns can be quantified using fractional flow reserve (FFR) pullbacks incorporating the pullback pressure gradient (PPG) calculation. This study aimed to establish the capacity of PPG to predict optimal revascularisation and procedural outcomes. METHODS: This prospective, investigator-initiated, single-arm, multicentre study enrolled patients with at least one epicardial lesion with an FFR ≤ 0.80 scheduled for PCI. Manual FFR pullbacks were employed to calculate PPG. The primary outcome of optimal revascularisation was defined as a post-PCI FFR ≥ 0.88. RESULTS: 993 patients with 1044 vessels were included. The mean FFR was 0.68 ± 0.12, PPG 0.62 ± 0.17, and post-PCI FFR 0.87 ± 0.07. PPG was significantly correlated with the change in FFR after PCI (r=0.65, 95% CI 0.61-0.69, p<0.001) and demonstrated excellent predicted capacity for optimal revascularisation (AUC 0.82, 95% CI 0.79-0.84, p<0.001). Conversely, FFR alone did not predict revascularisation outcomes (AUC 0.54, 95% CI 0.50-0.57). PPG influenced treatment decisions in 14% of patients, redirecting them from PCI to alternative treatment modalities. Periprocedural myocardial infarction occurred more frequently in patients with low PPG (<0.62) compared to those with focal disease (OR 1.71, 95% CI: 1.00-2.97). CONCLUSIONS: Pathophysiological CAD patterns distinctly affect the safety and effectiveness of PCI. The PPG showed an excellent predictive capacity for optimal revascularisation and demonstrated added value compared to a FFR measurement.

RESUMEN

Coronary vasomotor disorders (CVD) are characterized by transient hypercontraction of coronary vascular smooth muscle cells, leading to hypercontraction of epicardial and/or microvascular coronary circulation. CVDs play a relevant role in the pathogenesis of ischemia, angina and myocardial infarction with non-obstructive coronary arteries. Invasive provocative testing with intracoronary Acetylcholine (ACh) administration is the gold standard tool for addressing CVD, providing relevant therapeutic and prognostic implications. However, safety concerns preclude the widespread incorporation of the ACh test into clinical practice. The purpose of this review is to shed light on the pathophysiology underlying CVD and on the clinical role of the ACh test, focusing on safety profile and prognostic implications. We will also discuss contemporary evidence on the management of CVD and the role of the ACh test in driving a personalized approach of patients with CVD.

RESUMEN

BACKGROUND: Adverse cardiac events are common in older patients with non-ST elevation acute coronary syndrome (NSTEACS), yet prognostic predictors are still lacking. This study investigated the long-term prognostic significance of non-invasive measures including endothelial function, carotid intima-media thickness (CIMT), and vascular stiffness in older NSTEACS patients referred for invasive treatment. METHODS: NSTEACS patients aged 75 years and older recruited to a multicentre cohort study (NCT01933581) were assessed for baseline endothelial function using endoPAT logarithm of reactive hyperemia index (LnRHI), CIMT using B-mode ultrasound, and vascular stiffness using carotid-femoral pulse wave velocity (cfPWV). Long-term outcomes included major adverse cardiovascular events (MACE), a composite of death, reinfarction, urgent revascularization, stroke/transient ischemic attack, and significant bleeding. RESULTS: Recruitment resulted in 214 patients assessed for LnRHI, 190 patients assessed for CIMT and 245 patients assessed for cfPWV. For LnRHI group (median follow-up 4.73 years [IQR: 1.41-5.00]), Cox regression analysis revealed a trend towards increased risk of MACE (HR: 1.24 [95% CI: 0.80-1.93]; P  = 0.328) and mortality (HR: 1.49 [95% CI: 0.86-2.59]; P  = 0.157), but no significance was reached. No difference for other components of MACE was found. For CIMT group (median follow up 4.74 years [IQR: 1.55-5.00]), no statistically significant difference in MACE was found (HR: 0.92 [95% CI: 0.53-1.59]; P  = 0.754). Similarly, for cfPWV group (median follow-up 4.96 years [IQR: 1.55-5.00]), results did not support prognostic significance (for MACE, HR: 0.95 [95% CI: 0.65-1.39]; P  = 0.794). CONCLUSION: Endothelial function, CIMT and vascular stiffness were proven unsuitable as strong prognostic predictors in older patients with NSTEACS. CLINICAL TRIAL REGISTRATION: NCT01933581.

RESUMEN

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.

RESUMEN

BACKGROUND: The diagnosis of myocardial infarction (MI) in the presence of heart failure (HF) presents a clinical problem. While diagnostic algorithms using high-sensitivity cardiac troponin have been established for suspected MI, their accuracy in patients with HF remains uncertain. This study aims to assess the diagnostic accuracy of high-sensitivity troponin I (TnI) levels in identifying acute MI among patients with HF, focusing on baseline, absolute and relative TnI changes. METHODS: Data from 562 individuals admitted to the emergency department with suspected MI were retrospectively analysed. Two-point TnI and baseline brain natriuretic peptide (BNP) test results were available. HF status was determined based on clinical, laboratory and instrumental criteria. RESULTS: Among the 562 patients, 299 (53.2%) were confirmed having MI. Baseline TnI demonstrated predictive capability for MI in the overall population (area under the curve (AUC) 0.63), while TnI relative change exhibited superior performance (AUC 0.83). Baseline TnI accuracy varied significantly by group, notably decreasing in the third group (severe HF) (AUC 0.54) compared with the first and second groups (AUC 0.67 and AUC 0.71, respectively). TnI relative change demonstrated consistent accuracy across all groups, with AUCs of 0.79, 0.79 and 0.89 for the first, second and third groups, respectively, even after adjustment for age, sex and glomerular filtration rate. DISCUSSION: Troponin relative change is a reliable predictor of MI, even in patients with acute HF. Baseline TnI accuracy is influenced by HF severity. It is essential to consider HF status and BNP levels when employing high-sensitivity cardiac troponin testing to rule out suspected MIs.

RESUMEN

BACKGROUND: The underlying mechanisms responsible for the clinical benefits following coronary sinus narrowing and pressure elevation remain unclear. The present study aims to investigate whether coronary sinus narrowing improves the indexes of coronary microcirculatory function. METHODS: Patients with refractory angina who had a clinical indication for reducer implantation underwent invasive physiological assessments before and 4 months after the procedure. The primary outcome was the change in the values of the index of microcirculatory resistance. Secondary end points included changes in coronary flow reserve and the resistive resistance ratio values. Angina status was assessed with the Canadian Cardiology Society class and the Seattle Angina Questionnaire. RESULTS: Twenty-four patients with a history of obstructive coronary artery disease and prior coronary revascularization (surgical and percutaneous) treated with reducer implantation were enrolled, and 21 of them (87%) underwent repeated invasive coronary physiological assessment after 4 months. The index of microcirculatory resistance values decreased from 33.35±19.88 at baseline to 15.42±11.36 at 4-month follow-up (P<0.001; mean difference, -17.90 [95% CI, -26.16 to -9.64]). A significant (≥20% from baseline) reduction of the index of microcirculatory resistance was observed in 15 (71.4% [95% CI, 47.8%-88.7%]) patients. The number of patients with abnormal index of microcirculatory resistance (≥25) decreased from 12 (57%) to 4 (19%; P=0.016). Coronary flow reserve increased from 2.46±1.52 to 4.20±2.52 (mean difference, 1.73 [95% CI, 0.51-2.96]). Similar findings were observed for resistive resistance ratio values. Overall, 16 patients (76.1%) had an improvement of 1 Canadian Cardiology Society class. Seattle Angina Questionnaire summary score increase of around 3 points (3.01 [95% CI, 1.39-4.61]). CONCLUSIONS: Coronary sinus reduction implantation is associated with a significant improvement in the parameters of coronary microcirculatory function. These findings provide insights into the improvement of angina symptoms and may have implications for the treatment of coronary microvascular dysfunction.

RESUMEN

INTRODUCTION AND OBJECTIVES: After ST-segment myocardial infarction (STEMI), the impact of different adverse events on prognosis remains unknown. We aimed to assess very long-term predictors of patient-oriented composite endpoints (POCE) and investigate whether the occurrence of target vessel failure (TVF) vs a non-TVF event as the first event could potentially influence subsequent outcomes. METHODS: The EXAMINATION-EXTEND trial randomized STEMI patients to receive either an everolimus-eluting stent or a bare-metal stent. The follow-up period was 10 years. Predictors of POCE (a composite of all-cause death, any myocardial infarction, or any revascularization) were evaluated in the overall study population. The patients were stratified based on the type of first event (TVF-first vs non-TVF-first) and were compared in terms of subsequent POCE. TVF was defined as a composite of cardiac death, TV myocardial infarction, or TV revascularization. RESULTS: Out of the 1498 enrolled patients, 529 (35.3%) experienced a POCE during the 10-year follow-up. Independent predictors of POCE were age, diabetes mellitus, previous myocardial infarction, peripheral arterial disease, and multivessel coronary disease. The first event was a TVF in 296 patients and was a non-TVF in 233 patients. No significant differences were observed between TVF-first and non-TVF-first patients in terms of subsequent POCE (21.7% vs 39.3%, time ratio 1.79; 95%CI, 0.87-3.67;P=.12) or its individual components. CONCLUSIONS: At the 10-year follow-up, approximately one-third of STEMI patients had experienced at least 1 POCE. Independent predictors of these events were age, diabetes, and more extensive atherosclerotic disease. The occurrence of a TVF or a non-TVF as the first event did not seem to influence subsequent outcomes. TRIAL REGISTRATION NUMBER: NCT04462315.

RESUMEN

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.

RESUMEN

Femoral access site-related bleeding represent a prognostically impactful issue in interventional cardiology. The impact of a combined use of ultrasound guidance for femoral access and vascular closure device deployment for arteriotomy closure in femoral artery procedures on bleeding complications is still largely unknown. A systematic review was conducted on Pubmed (Medline), Cochrane library and Biomed Central databases between March and April 2023. A total of 9 studies have been selected, of namely 4 registries, 4 prospective studies and one randomized clinical trial. A systematic use of US guidance to access femoral artery resulted feasible and not time consuming, reduced venipuncture and increased first attempt success. Combination of US guidance and deployment of VCD's had the capacity to further decrease vascular and bleeding combination, especially in those patients at a higher risk of post-procedural bleeding. Ultrasound can be easily used during closure device deployment to reduce device failure and major vascular complications.

RESUMEN

#FullPhysiology is a comprehensive and systematic approach to evaluate patients with suspected coronary disease using PressureWire technology (Abbott Vascular, Santa Clara, CA, USA). This advancement in technology enables the investigation of each component of the coronary circulation, including epicardial, microvascular, and vasomotor function, without significantly increasing procedural time or technical complexity. By identifying the predominant physiopathology responsible for myocardial ischemia, #FullPhysiology enhances precision medicine by providing accurate diagnosis and facilitating tailored interventional or medical treatments. This overview aims to provide insights into modern coronary physiology and describe a systematic approach to assess epicardial flow-limiting disease, longitudinal physiological vessel analysis, microvascular and vasomotor dysfunction, as well as post- percutaneous coronary intervention (PCI) physiological results.

RESUMEN

The present study investigates the prognostic value of the Syntax Score II 2020 corrected for flow-limiting lesions and its ability to better address treatment by benefit prediction among patients with left main or multivessel disease. We analyzed 1274 patients from the HALE-BOPP cohort and integrated the Syntax Score II 2020 with the result of the fractional flow reserve (FFR) evaluation. Absolute risk difference (ARD) between surgical and percutaneous revascularization was calculated for anatomic and functional Syntax Score II 2020 predicted mortality. The ARD allowed to stratify the population into two large categories: "coronary artery bypass graft (CABG) better" with ARD ≥ 4.5% and "CABG-percutaneous coronary intervention (PCI) equipoise" with ARD < 4.5%. The mean global anatomical Syntax Score was 15.5 ± 9.2, whereas the functional one was 9.5 ± 10 (p < 0.01). Using the anatomic Syntax Score II 2020, 881 patients had a CABG-PCI equipoise. This number increased to 1041 after considering only flow-limiting lesions by FFR (p < 0.001); therefore, 40% of CABG better patients were reclassified within the CABG-PCI equipoise category. Kaplan-Maier curves showed similar actual survival rates for patients originally with CABG-PCI equipoise and those reclassified, in both cases higher than those from CABG better patients (p < 0.01). The integration between Syntax Score II 2020 and physiology is feasible, and merging clinical, anatomic and functional data allows for better risk prediction and therapeutic guidance.
