RESUMO
BACKGROUND: Ten to fifteen percent of chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) are unsuccessful in contemporary practice. Subintimal tracking and re-entry (STAR) (one form of "investment procedure") with staged reattempt and stenting may further increase the ultimate success and safety of CTO as a bailout strategy. The optimal timing for staged stenting after STAR is unknown. METHODS AND RESULTS: We designed a six-center, prospective randomized trial with a planned enrollment of 150 patients where STAR is utilized in case of impending failure. The primary aim is to evaluate the optimal timing of the staged PCI after STAR by randomizing the timing to earlier (5-7 weeks) versus later (12-14 weeks) staged PCI. The primary endpoint of the study is the technical success rate of the staged procedure. The secondary endpoints include: (1) the rate of thrombolysis in myocardial infarction 3 flow at the start of staged intervention, (2) rate of partial technical and procedural success of the staged procedure, (3) rate of in-hospital and 12-month major cardiac and cerebrovascular adverse events, and (4) change in patient-reported quality at 30 days, 6 months, and 12 months assessed by Seattle Angina Questionnaire. CONCLUSION: This study will ascertain the optimal timing of staged stenting after bail-out STAR approach in contemporary CTO PCI (ClinicalTrials.gov NCT05089864).
RESUMO
BACKGROUND: Risk stratification before chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is important to inform procedural planning as well as patients and their families. We sought to externally validate the PROGRESS-CTO complication risk scores in the OPEN-CTO registry. METHODS: OPEN-CTO is a prospective registry of 1000 consecutive CTO PCIs performed at 12 experienced US centers using the hybrid algorithm. Endpoints of interest were in-hospital all-cause mortality, need for pericardiocentesis, acute myocardial infarction (MI), and major adverse cardiovascular events (MACE) (a composite of all-cause mortality, stroke, periprocedural MI, urgent repeat revascularization, and tamponade requiring pericardiocentesis). Model discrimination was assessed with the area under the curve (AUC) method, and calibration with the observed-versus-predicted probability method. RESULTS: Mean age was 65.4 ± 10.3 year, and 36.5% of patients had prior coronary artery bypass graft. Overall, 41 patients (4.1%) suffered MACE, 9 (0.9%) mortality, 26 (2.6%) acute MI, and 11 (1.1%) required pericardiocentesis. Technical success was achieved in 86.3%. Patients who experienced MACE had higher anatomic complexity, and more often required antegrade dissection/reentry and the retrograde approach. Increasing PROGRESS-CTO MACE scores were associated with increasing MACE rates: 0.5% (score 0-1), 2.4% (score 2), 3.7% (score 3), 4.5% (score 4), 7.8% (score 5), 13.0% (score 6-7). The AUC were as follows: MACE 0.72 (95% confidence interval [CI]: 0.66-0.78), mortality 0.79 (95% CI: 0.66-0.95), pericardiocentesis 0.71 (95% CI: 0.60-0.82), and acute MI 0.57 (95% CI: 0.49-0.66). Calibration was adequate for MACE and mortality, while the models underestimated the risk of pericardiocentesis and acute MI. CONCLUSIONS: In a large external cohort of patients treated with the hybrid algorithm by experienced CTO operators, the PROGRESS-CTO MACE, mortality, and pericardiocentesis risk scores showed good discrimination, while the acute MI score had inferior performance.

BACKGROUND: Indications and outcomes for percutaneous ventricular assist device (pVAD) use in surgically ineligible patients undergoing percutaneous coronary intervention (PCI) remain poorly characterized. AIMS: We sought to describe the use and timing of pVAD and outcome in surgically ineligible patients. METHODS: Among 726 patients enrolled in the prospective OPTIMUM study, clinical and health status outcomes were assessed in patients who underwent pVAD-assisted PCI and those without pVAD. RESULTS: Compared with patients not receiving pVAD (N = 579), those treated with pVAD (N = 142) more likely had heart failure, lower left ventricular ejection fraction (30.7 ± 13.6 vs. 45.9 ± 15.5, p < 0.01), and higher STS 30-day predicted mortality (4.2 [2.1-8.0] vs. 3.3 [1.7-6.6], p = 0.01) and SYNTAX scores (36.1 ± 12.2, vs. 31.5 ± 12.1, p < 0.01). While the pVAD group had higher in-hospital (5.6% vs. 2.2%, p = 0.046), 30-day (9.0% vs. 4.0%, p = 0.01) and 6-month (20.4% vs. 11.7%, p < 0.01) mortality compared to patients without pVAD, this difference appeared to be largely driven by significantly higher mortality among the 20 (14%) patients with unplanned pVAD use (30% in-hospital mortality with unplanned PVAD vs. 1.6% with planned, p < 0.01; 30-day mortality, 38.1% vs. 4.5%, p < 0.01). The degree of 6-month health status improvement among survivors was similar between groups. CONCLUSION: Surgically ineligible patients with pVAD-assisted PCI had more complex baseline characteristics compared with those without pVAD. Higher mortality in the pVAD group appeared to be driven by very poor outcomes by patients with unplanned, rescue pVAD.

PURPOSE OF THE REVIEW: The goal of this paper is to review the current evidence surrounding CTO PCI in patients with low EF, the most high-risk population to treat. We also present pertinent case examples and offer practical tips to increase success and lower complications when performing CTO PCI in patients with low EF. RECENT FINDINGS: In a prospective randomized control study, greater improvement in angina frequency and quality of life, assessed by the Seattle Angina Questionnaire, was achieved by CTO PCI compared to optimal medical therapy. Furthermore, after successful CTO PCI, improvements in health status were similar in patients with both low and normal EF. CTO PCI can not only ameliorate symptoms of angina in patients with low EF but may also potentially improve EF in carefully selected populations. However, information regarding treatment of this high-risk population is lacking and large-scale studies targeting patients with severely reduced EF remain necessary.

BACKGROUND: Perforation is the most frequent complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and is associated with adverse events including mortality. METHODS: Among 1,000 consecutive patients enrolled in 12 center prospective CTO PCI study (OPEN CTO), all perforations were reviewed by the angiographic core-lab. Eighty-nine patients (8.9%) with angiographic perforation were compared to 911 patients without perforation. We sought to describe the clinical and angiographic predictors of angiographic perforation during CTO PCI and develop a risk prediction model. RESULTS: Among eight clinically important candidate variables, independent risk factors for perforation included prior CABG (OR 2.0 [95% CI, 1.2-3.3], p < .01), occlusion length (OR 1.2 per 10 mm increase [95% CI, 1.1-1.3], p < .01), ejection fraction (OR 1.2 per 10% decrease [95% CI, 1.1-1.5], p < .01), age (OR 1.3 per 5 year increase [95%CI, 1.1-1.5], p < .01), and heavy calcification (OR 1.7 [95% CI, 1.0-2.7], p = .04). Three other potential candidate variables, glomerular filtration rate, proximal cap ambiguity, and target vessel, were not independently associated with perforation. The model was internally validated using bootstrapping methods. From the full model, a simplified perforation prediction score (OPEN-CLEAN score: CABG, Length [occlusion], EF < 50%, Age, CalcificatioN) was developed, which discriminated the risk of angiographic perforation well (c-statistics = 0.75) and demonstrated good calibration. CONCLUSION: This simple 5-variable prediction score may help CTO operators to risk-stratify patients for angiographic perforation using variables available prior to CTO PCI procedures.

OBJECTIVES: To develop a model to predict risk of in-hospital bleeding following endovascular peripheral vascular intervention. BACKGROUND: Peri-procedural bleeding is a common, potentially preventable complication of catheter-based peripheral vascular procedures and is associated with increased mortality. We used the National Cardiovascular Data Registry (NCDR) Peripheral Vascular Interventions (PVI) Registry to develop a novel risk-prediction model to identify patients who may derive the greatest benefit from application of strategies to prevent bleeding. METHODS: We examined all patients undergoing lower extremity PVI at 76 NCDR PVI hospitals from 2014 to 2017. Patients with acute limb ischemia (n = 1600) were excluded. Major bleeding was defined as overt bleeding with a hemoglobin (Hb) drop of ≥ 3 g/dl, any Hb decline of ≥ 4 g/dl, or a blood transfusion in patients with pre-procedure Hb ≥ 8 g/dl. Hierarchical multivariable logistic regression was used to develop a risk model to predict major bleeding. Model validation was performed using 1000 bootstrapped replicates of the population after sampling with replacement. RESULTS: Among 25,382 eligible patients, 1017 (4.0%) developed major bleeding. Predictors of bleeding included age, female sex, critical limb ischemia, non-femoral access, prior heart failure, and pre-procedure hemoglobin. The model demonstrated good discrimination (optimism corrected c-statistic = 0.67), calibration (corrected slope = 0.98, intercept of -0.04) and range of predicted risk (1%-18%). CONCLUSIONS: Post-procedural PVI bleeding risk can be predicted based upon pre- and peri-procedural patient characteristics. Further studies are needed to determine whether this model can be utilized to improve procedural safety through developing and targeting bleeding avoidance strategies.

BACKGROUND: No previous reports have described the comprehensive care pathways involved in chronic total occlusion percutaneous coronary intervention (CTO PCI). METHODS: In a study of 1,000 consecutive patients undergoing CTO PCI using hybrid approach, a systematic algorithm of selecting CTO PCI strategies, the procedural characteristics, complication rates, and patient reported health status outcomes through 12 months were assessed. RESULTS: Technical success of the index CTO PCI was 86%, with 89% of patients having at least one successful CTO PCI within 12 months. A total of 13.8% underwent CTO PCI of another vessel or reattempt of index CTO PCI within 1 year. At 1 year, the unadjusted major adverse cardiac and cerebral event (MACCE) rate was lower in patients with successful index CTO PCI compared to patients with unsuccessful index CTO PCI (9.4% vs. 14.6%, p = .04). The adjusted hazard ratios of myocardial infarction and death at 12 months were numerically lower in patients with successful index CTO PCI, compared to patients with unsuccessful index CTO PCI. Patients with successful index CTO PCI reported significantly greater improvement in health status throughout 12-months compared to patients with unsuccessful index CTO PCI. CONCLUSION: CTO-PCI in the real-world often require treatment of second CTO, non-CTO PCI or repeat procedures to treat initially unsuccessful lesions. Successful CTO PCI is associated with numerically lower MACCE at 1 year and persistent symptomatic improvement compared to unsuccessful CTO PCI. Understanding the relationship between the care pathways following CTO PCI and health status benefit requires further study.

OBJECTIVES: We sought to assess in-hospital and long-term outcomes of retrograde compared with antegrade-only percutaneous coronary intervention for chronic total occlusion (CTO PCI). BACKGROUND: Procedural and clinical outcomes following retrograde compared with antegrade-only CTO PCI remain unknown. METHODS: Using the core-lab adjudicated OPEN-CTO registry, we compared the outcomes of retrograde to antegrade-only CTO PCI. Primary endpoints included were in-hospital major adverse cardiac and cerebrovascular events (MACCE) (all-cause death, stroke, myocardial infarction [MI], emergency cardiac surgery, or clinically significant perforation) and MACCE at 1-year (all-cause death, MI, stroke, target lesion revascularization, or target vessel reocclusion). RESULTS: Among 885 single CTO procedures from the OPEN-CTO registry, 454 were retrograde and 431 were antegrade-only. Lesion complexity was higher (J-CTO score: 2.7 vs. 1.9; p < .001) and technical success lower (82.4 vs. 94.2%; p < .001) in retrograde compared with antegrade-only procedures. All-cause death was higher in the retrograde group in-hospital (2 vs. 0%; p = .003), but not at 1-year (4.9 vs. 3.3%; p = .29). Compared with antegrade-only procedures, in-hospital MACCE rates (composite of all-cause death, stroke, MI, emergency cardiac surgery, and clinically significant perforation) were higher in the retrograde group (10.8 vs. 3.3%; p < .001) and at 1-year (19.5 vs. 13.9%; p = .03). In sensitivity analyses landmarked at discharge, there was no difference in MACCE rates at 1 year following retrograde versus antegrade-only CTO PCI. Improvements in Seattle Angina Questionnaire Quality of Life scores at 1-year were similar between the retrograde and antegrade-only groups (29.9 vs 30.4; p = .58). CONCLUSIONS: In the OPEN-CTO registry, retrograde CTO procedures were associated with higher rates of in-hospital MACCE compared with antegrade-only; however, post-discharge outcomes, including quality of life improvements, were similar between technical modalities.

BACKGROUND: No previous reports have examined the impact of robotic-assisted (RA) chronic total occlusion (CTO) PCI on procedural duration or safety compared to totally manual CTO PCI. METHODS: Among 95 patients who underwent successful PCI of a single CTO lesion at two centers, 49 (52%) were performed RA and were performed 46 (48%) totally manually. Cockpit time was the time the primary operator entered to robotic cockpit until the procedure was complete. "Theoretical" cockpit time in the control group was time the primary operator would have entered the cockpit after lesion crossing until the procedure was complete. Major adverse events (MAEs) were the composite of death, myocardial infarction, clinical perforation, significant vessel dissection, arrhythmia, acute thrombosis, and stroke. RESULTS: The lesion characteristics, procedural time, and contrast dose were similar. All procedures except for one (2%) selected for robotic completion after lesion crossing were completed successfully. The frequency of MAE was similar between groups and there were no in-hospital deaths. The cockpit time was 8 min longer in RA CTO PCI than the theoretical cockpit time in totally manual CTO PCI (40.6 ± 12.7 vs. 32.1 ± 17.8, p < .01). CONCLUSION: RA CTO PCI was not associated with excess adverse events compared with totally manual CTO PCI and resulted in an average 41 min cockpit time equaling to 48% of procedure time without radiation exposure or requirement for the primary operator to wear a lead apron. Understanding the relationship between cockpit time and reductions in radiation exposure and lead apron-related orthopedic complications for operators requires future study.

BACKGROUND: Successful chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can markedly reduce angina symptom burden, but many patients often remain on multiple antianginal medications (AAMs) after the procedure. It is unclear when, or if, AAMs can be de-escalated to prevent adverse effects or limit polypharmacy. We examined the association of de-escalation of AAMs after CTO PCI with long-term health status. METHODS: In a 12-center registry of consecutive CTO PCI patients, health status was assessed at 6â¯months after successful CTO PCI with the Seattle Angina Questionnaire and the Rose Dyspnea Scale. Among patients with technical CTO PCI success, we examined the association of AAM de-escalation with 6-month health status using multivariable models adjusting for revascularization completeness and predicted risk of post-PCI angina (using a validated risk model). We also examined predictors and variability of AAMs de-escalation. RESULTS: Of 669 patients with technical success of CTO PCI, AAMs were de-escalated in 276 (35.9%) patients at 1â¯month. Patients with AAM de-escalation reported similar angina and dyspnea rates at 6â¯months compared with those whose AAMs were reduced (any angina: 22.5% vs 20%, Pâ¯=â¯.43; any dyspnea: 51.8% vs 50.1%, Pâ¯=â¯.40). In a multivariable model adjusting for complete revascularization and predicted risk of post-PCI angina, de-escalation of AAMs at 1â¯month was not associated with an increased risk of angina, dyspnea, or worse health status at 6â¯months. CONCLUSIONS: Among patients with successful CTO PCI, de-escalation of AAMs occurred in about one-third of patients at 1â¯month and was not associated with worse long-term health status.

OBJECTIVES: To determine whether a variation of an abandoned antegrade percutaneous coronary intervention (PCI) technique, termed subintimal tracking and reentry (STAR), could be a safe and effective strategy to contend with complex coronary chronic total occlusions (CTO) when other strategies fail. BACKGROUND: Complex CTOs require advanced techniques such as the retrograde approach, which is associated with higher complication rates than antegrade strategies. METHODS: The medical records of 32 consecutive patients who underwent deferred stenting following STAR (DSS) between January 2015 and May 2017 at a high-volume referral center were retrospectively reviewed. The primary endpoint was technical success at the time of a second procedure following STAR-based balloon angioplasty, defined as successful stenting or the presence of Thrombolysis in Myocardial Infarction Study Group (TIMI) 3 flow with <50% residual stenosis if the vessel caliber was inappropriate for stenting. RESULTS: Of 781 CTO PCI procedures, STAR was performed in 45 (5.8%) and DSS in 32 (4.1%), constituting the analysis cohort. The median Japanese-CTO score was 2.5 [interquartile range (IQR) 1.0-3.0]. Median inter-procedure time was 2.4 months [1.7-3.3 months]. Technical success was achieved in 28 (88%) patients; 23 (72%) patients were treated with stents and 5 (16%) with balloon angioplasty alone. Combined complications included one clinical perforation, one MI, and one stent thrombosis. CONCLUSIONS: Deferred stenting after subintimal plaque modification via the STAR technique is a safe and effective strategy to contend with complex CTO lesions when other techniques are prohibitively high risk or have failed.

OBJECTIVES: We sought to determine the impact of subintimal plaque modification (SPM) on early health status following unsuccessful chronic total occlusion (CTO) PCI. BACKGROUND: Intentionally dilating the subintimal space during unsuccessful CTO PCI to facilitate flow through dissection planes and improve success of repeat PCI attempts is a technique used by some hybrid operators, and may improve health status by restoring distal vessel flow despite unsuccessful CTO PCI. METHODS: We studied 138 patients who underwent unsuccessful CTO PCI in a 12-center CTO PCI registry. Safety was assessed by comparing in-hospital outcomes of patients undergoing unsuccessful CTO PCI with and without SPM. The association between SPM and health status was quantified using the Seattle Angina Questionnaire Summary Score (SAQ SS), and the association between SPM and SAQ SS was determined using multivariable regression. RESULTS: SPM was performed in 59 patients (42.8%). Complication rates were similar comparing those with and without SPM. At 1-month, patients treated with SPM had larger increases in SAQ SS compared to patients who were not (28.3 ± 21.7 vs. 16.8 ±20.2, P = 0.012), and SPM was associated with an adjusted mean 10.5 point (95% CI 1.4-19.7, P = 0.02) greater SAQ SS improvement through 30 days. CONCLUSION: SPM was performed in almost half of unsuccessful CTO PCIs and was not associated with increased procedural complications. SPM was independently associated with better patient-reported health status at 30 days. Further studies are needed to assess the necessity of subsequent PCI in patients with significant health status improvements after SPM.

BACKGROUND: The frequency of noncardiac chest pain (CP) hospitalization after acute myocardial infarction (AMI) is unknown, and its significance from patients' perspectives is not studied. OBJECTIVES: To assess the frequency of noncardiac CP admissions after AMI and its association with patients' self-reported health status. METHODS: We identified cardiac and noncardiac CP hospitalizations in the year after AMI from the 24-center TRIUMPH registry. Hierarchical repeated-measures regression was used to identify the association of these hospitalizations with patients' self-reported health status using the Seattle Angina Questionnaire Quality of Life domain (SAQ QoL) and Short Form 12 (SF-12) physical (PCS) and mental (MCS) component summary scores. RESULTS: Of 3,099 patients, 318 (10.3%) were hospitalized with CP, of whom 92 (28.9%) were hospitalized for noncardiac CP. Compared with patients not hospitalized with CP, noncardiac CP hospitalization was associated with poorer health status (SAQ QoL-adjusted differences: -8.9 points [95% CI -12.1 to -5.6]; SF-12 PCS: -2.5 points [95% CI -4.2 to -0.8] and SF-12 MCS: -3.5 points [95% CI -5.1 to -1.9]). The SAQ QoL for patients hospitalized with noncardiac CP was similar to patients hospitalized with cardiac CP (adjusted difference: 0.6 points [95% CI -3.2 to 4.5]; SF-12 PCS (0.9 points [95% CI -1.1 to 2.9]), but was worse with regard to SF-12 MCS (adjusted difference: -2.0 points [95% CI -3.9 to -0.2]). CONCLUSIONS: Noncardiac CP accounted for a third of CP hospitalizations within 1 year of AMI and was associated with similar disease-specific QoL as well as general physical and mental health status impairment compared with cardiac CP hospitalization.

Background: Intracoronary (IC) imaging for percutaneous coronary intervention (PCI) is associated with better patient outcomes and carries a class IIA guideline recommendation, but it remains rarely used. We sought to characterize hospital-level variability in IC imaging for PCI in the United States and to identify factors that may explain this variability. Methods: Patients who underwent PCI, with or without IC imaging, in the Nationwide Readmissions Database (2016-2020) were included. A regression model with a random effect for site was used to generate the median odds ratio (MOR) of IC imaging use for a patient at one site vs another, sequentially adjusting for procedural, patient, and hospital factors to examine the extent to which different factors account for this variability. Results: The analytic cohort included 1,328,517 PCI procedures (patient mean age 65.8 years, 32.4% female, IC imaging used in 9.2%) at 1068 hospitals. The median hospital use of IC imaging increased from 2.7% (IQR, 0.6-7.7) in 2016 to 6.3% (IQR, 1.7-17.8) in 2020. In 2020, the MOR for IC imaging during PCI was 4.6 (IQR, 4.3-5.0), indicating a >4-fold difference in the odds of a patient undergoing IC imaging with PCI at one random hospital vs another. Adjusting for procedure, patient, and hospital factors did not meaningfully alter the MOR. Conclusion: The average US hospital uses IC imaging for <1 in 15 PCI procedures, with marked variability across hospitals. Strategies to increase and standardize the use of IC imaging are needed to improve the quality of PCI in the United States.
RESUMO
Background Although chronic total occlusions (CTOs) are common in older adults, they are less likely to be offered CTO percutaneous coronary intervention for angina relief than younger adults. The health status impact of CTO percutaneous coronary intervention in adults aged ≥75 years has not been studied. We sought to compare technical success rates and angina-related health status outcomes at 12 months between adults aged ≥75 and <75 years in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion) registry. Methods and Results Angina-related health status was assessed with the Seattle Angina Questionnaire (score range 0-100, higher scores denote less angina). Technical success rates were compared using hierarchical modified Poisson regression, and 12-month health status was compared using hierarchical multivariable linear regression between adults aged ≥75 and <75 years. Among 1000 participants, 19.8% were ≥75 years with a mean age of 79.5±4.1 years. Age ≥75 years was associated with a lower likelihood of technical success (adjusted risk ratio=0.92 [95% CI, 0.86-0.99; P=0.02]) and numerically higher rates of in-hospital major adverse cardiovascular events (9.1% versus 5.9%, P=0.10). There was no difference in Seattle Angina Questionnaire Summary Score at 12 months between adults aged ≥75 and <75 years (adjusted difference=0.9 [95% CI, -1.4 to 3.1; P=0.44]). Conclusions Despite modestly lower success rates and higher complication rates, adults aged ≥75 years experienced angina-related health status benefits after CTO-percutaneous coronary intervention that were similar in magnitude to adults aged <75 years. CTO percutaneous coronary intervention should not be withheld based on age alone in otherwise appropriate candidates.

BACKGROUND: Percutaneous coronary intervention (PCI) is increasingly used to revascularize patients ineligible for CABG, but few studies describe these patients and their outcomes. OBJECTIVES: This study sought to describe characteristics, utility of risk prediction, and outcomes of patients with left main or multivessel coronary artery disease ineligible for coronary bypass grafting (CABG). METHODS: Patients with complex coronary artery disease ineligible for CABG were enrolled in a prospective registry of medical therapy + PCI. Angiograms were evaluated by an independent core laboratory. Observed-to-expected 30-day mortality ratios were calculated using The Society for Thoracic Surgeons (STS) and EuroSCORE (European System for Cardiac Operative Risk Evaluation) II scores, surgeon-estimated 30-day mortality, and the National Cardiovascular Data Registry (NCDR) CathPCI model. Health status was assessed at baseline, 1 month, and 6 months. RESULTS: A total of 726 patients were enrolled from 22 programs. The mean SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score was 32.4 ± 12.2 before and 15.0 ± 11.7 after PCI. All-cause mortality was 5.6% at 30 days and 12.3% at 6 months. Observed-to-expected mortality ratios were 1.06 (95% CI: 0.71-1.36) with The Society for Thoracic Surgeons score, 0.99 (95% CI: 0.71-1.27) with the EuroSCORE II, 0.59 (95% CI: 0.42-0.77) using cardiac surgeons' estimates, and 4.46 (95% CI: 2.35-7.99) using the NCDR CathPCI score. Health status improved significantly from baseline to 6 months: SAQ summary score (65.9 ± 22.5 vs 86.5 ± 15.1; P < 0.0001), Kansas City Cardiomyopathy Questionnaire summary score (54.1 ± 27.2 vs 82.6 ± 19.7; P < 0.0001). CONCLUSIONS: Patients ineligible for CABG who undergo PCI have complex clinical profiles and high disease burden. Following PCI, short-term mortality is considerably lower than surgeons' estimates, similar to surgical risk model predictions but is over 4-fold higher than estimated by the NCDR CathPCI model. Patients' health status improved significantly through 6 months.

Anemia is well recognized as a marker of poor prognosis in patients with cardiovascular disease. Despite increasing awareness that anemia is associated with higher mortality, more frequent hospitalization, and worse health status, it remains unclear whether treating chronic anemia improves patients' outcomes. The importance of studying hospital-acquired anemia (HAA), and recognizing which patients are at high risk for developing HAA early in the course of their hospitalization, is underscored by the potential opportunities for HAA prevention and management. This article reviews the incidence of HAA, risk factors for developing HAA, and its relationship with clinical outcomes.

Background Given that percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) is indicated primarily for symptom relief, identifying patients most likely to benefit is critically important for patient selection and shared decision-making. Therefore, we identified factors associated with residual angina frequency after CTO PCI and developed a model to predict postprocedure anginal burden. Methods and Results Among patients in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry, we evaluated the association between patient characteristics and residual angina frequency at 6 months, as assessed by the Seattle Angina Questionnaire Angina Frequency Scale. We then constructed a prediction model for angina status after CTO PCI using ordinal regression. Among 901 patients undergoing CTO PCI, 28% had no angina, 31% had monthly angina, 30% had weekly angina, and 12% had daily angina at baseline. Six months later, 53% of patients had a ≥20-point increase in Seattle Angina Questionnaire Angina Frequency Scale score. The final model to predict residual angina after CTO PCI included baseline angina frequency, baseline nitroglycerin use frequency, dyspnea symptoms, depressive symptoms, number of antianginal medications, PCI indication, and presence of multiple CTO lesions and had a C index of 0.78. Baseline angina frequency and nitroglycerin use frequency explained 71% of the predictive power of the model, and the relationship between model components and angina improvement at 6 months varied by baseline angina status. Conclusions A 7-component OPEN-AP (OPEN-CTO Angina Prediction) score can predict angina improvement and residual angina after CTO PCI using variables commonly available before intervention. These findings have implications for appropriate patient selection and counseling for CTO PCI.

BACKGROUND: Guidelines endorse coronary artery bypass as the preferred revascularization strategy for patients with left main and/or multivessel coronary artery disease (CAD). However, many patients are deemed excessively high risk for surgery after Heart Team evaluation. No prospective studies have examined contemporary treatment patterns, rationale for surgical decision-making, completeness of revascularization with percutaneous coronary intervention (PCI), and outcomes in this high-risk population with advanced CAD. METHODS: We designed the Outcomes of Percutaneous RevascularizaTIon for Management of SUrgically Ineligible Patients with Multivessel or Left Main Coronary Artery Disease (OPTIMUM) registry, a prospective, multicenter study of patients with "surgical anatomy" determined to be at prohibitive risk for bypass surgery. The primary outcome is comparison of observed to predicted 30-day mortality, with secondary outcomes of patient-reported health status and the association between completeness of revascularization and clinical outcomes. Patient characteristics driving surgical risk determinations will be reported, and peri-operative risk will be assessed using validated scoring methods. Angiograms will be assessed by an independent core laboratory, and clinical events will be adjudicated. RESULTS: Clinical outcomes assessments will include 30-day and 1-year cardiovascular events, health status at 1, 6 and 12-months, and 5-year mortality. CONCLUSIONS: OPTIMUM is the first prospective, multicenter study to examine treatment strategies and outcomes among multivessel CAD patients deemed ineligible for surgical revascularization after Heart Team assessment. This registry will provide unique insights into the clinical decision-making, revascularization practices, safety, effectiveness, and health status outcomes in this high-risk population.

BACKGROUND: Hospital-acquired anemia (HAA) is common during acute myocardial infarction (AMI) and associated with higher long-term mortality. The relationship between HAA and adverse in-hospital outcomes may be particularly relevant to hospitals' efforts to implement prevention programs, but the association between HAA and in-hospital mortality is unclear. METHODS: We studied 17,676 patients with AMI with normal admission hemoglobin level who did not undergo bypass surgery. Hospital-acquired anemia was defined as development of new anemia during hospitalization (based on nadir hemoglobin) using age-, gender-, and race-specific criteria. In-hospital mortality of patients with mild (hemoglobin level less than HAA threshold but >11 g/dL), moderate (hemoglobin level 9-11 g/dL), and severe HAA (hemoglobin level, < 9 g/dL) was compared with those without HAA using hierarchical logistic regression, adjusting for site and potential confounders. RESULTS: Hospital-acquired anemia developed in 10,166 patients (57.5%); 6,615 (37.4%) had mild; 2,740 (15.5%), moderate; and 811 (4.6%), severe HAA. In-hospital mortality was higher in patients with HAA and increased with HAA severity (no HAA 266 [3.5%], mild HAA 260 [3.9%], moderate HAA 222 [8.1%], and severe HAA 148 [18.3%], P < .001). The adjusted odds of in-hospital death were greater in patients with moderate (odds ratio 1.38, 95% CI 1.10-1.73) and severe HAA (3.39, 95% CI 2.59-4.44) versus no HAA. CONCLUSIONS: Moderate and severe HAAs are independently associated with higher in-hospital mortality during AMI. Studies are needed to determine whether HAA is preventable and if preventing HAA improves outcomes.
