RESUMEN
BACKGROUND: Limited data exist around the utility of intracoronary imaging (ICI) during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and cardiogenic shock (CS), who are inherently at a high risk of stent thrombosis (ST). METHODS: All PCI procedures for ACS patients with CS in England and Wales between 2014 and 2020 were retrospectively analysed, stratified into two groups: ICI and angiography-guided groups. Multivariable logistic regression analyses were performed to examine odds ratios (OR) of in-hospital outcomes, including major adverse cardiovascular and cerebrovascular events (MACCE; composite of all-cause mortality, acute stroke/transient ischaemic attack (TIA), and reinfarction) and major bleeding, in the ICI-guided group compared with angiography-guided PCI. RESULTS: Of 15,738 PCI procedures, 1240(7.9%) were ICI-guided. The rate of ICI use amongst those with CS more than doubled from 2014 (5.7%) to 2020 (13.3%). The ICI-guided group were predominantly younger, males, with a higher proportion of non-ST-elevation ACS and ST. MACCE was significantly lower in the ICI-guided group compared with the angiography-guided group (crude: 29.8% vs. 38.2%, adjusted odds ratio (OR) 0.65 95% confidence interval [CI] 0.56-0.76), driven by lower all-cause mortality (28.6% vs. 37.0%, OR 0.65 95% CI 0.55-0.75). There were no differences in other secondary outcomes between groups. CONCLUSION: ICI use among CS patients has more than doubled over 6 years but remains significantly under-utilized, with less than 1-in-6 patients in receipt of ICI-guided PCI by 2020. ICI-guided PCI is associated with prognostic benefits in CS patients and should be more frequently utilized to increase their long-term survival.

INTRODUCTION: The impact of a vascular complication (VC) in the setting of intraaortic balloon pump (IABP) supported PCI on clinical outcomes is unclear. METHODS: Using data from the BCIS National PCI Database, multivariate logistic regression was used to identify independent predictors of a VC. Propensity scoring was used to quantify the association between a VC and outcomes. RESULTS: Between 2007 and 2014, 9,970 PCIs in England and Wales were supported by IABP (1.6% of total PCI), with 224 femoral VCs (2.3%). Annualized rates of a VC reduced as the use of radial access for PCI increased. The independent predictors of a VC included a procedural complication (odds ratio [OR] 2.9, p < .001), female sex (OR 2.3, p < .001), PCI for stable angina (OR 3.47, p = .028), and use of a glycoprotein inhibitor (OR 1.46 [1.1:2.5], p = .04), with a lower likelihood of a VC when radial access was used for PCI (OR 0.48, p = .008). A VC was associated with a higher likelihood of transfusion (OR 5.7 [3.5:9.2], p < .0001), acute kidney injury (OR 2.6 [1.2:6.1], p = .027), and periprocedural MI (OR 3.2 [1.5:6.7], p = .002) but not with adjusted mortality at discharge (OR 1.2 [0.8:1.7], p = .394) or 12-months (OR 1.1 [0.76:1.56], p = .639). In sensitivity analyses, there was a trend towards higher mortality in patients experiencing a VC who underwent PCI for stable angina (OR 4.1 [1.0:16.4], p value for interaction .069). Discussion and Conclusions Although in-hospital morbidity was observed to be adversely affected by occurrence of a VC during IABP-supported PCI, in-hospital and 1-year survival were similar between groups.

OBJECTIVES: This study aims to examine in-hospital gastrointestinal (GI) bleeding, its predictors and clinical outcomes, including long-term outcomes, in a national cohort of patients undergoing percutaneous coronary intervention (PCI) in England and Wales. BACKGROUND: GI bleeding remains associated with significant morbidity, mortality, and socioeconomic burden. METHODS: We examined the temporal changes in in-hospital GI bleeding in a national cohort of patients undergoing PCI between 2007 and 2014 in England and Wales, its predictors and prognostic consequences. Multivariate analysis was performed to identify independent risk factors between GI bleeding and 30-day mortality. Survival analysis was performed comparing patients with, and without, GI bleeding. RESULTS: There were 480 in-hospital GI bleeds in 549,298 patients (0.09%). Overall, rates of GI bleeding remained stable over time but a significant decline was observed for patients with ST segment elevation myocardial infarction (STEMI). The strongest predictors of bleeding events were STEMI-odds ratio (OR) 7.28 (95% confidence interval [95% CI] 4.82-11.00), glycoprotein IIb/IIIa inhibitor use OR 3.42 (95% CI 2.76-4.24) and use of circulatory support OR 2.65 (95% CI 1.90-3.71). Antiplatelets/coagulants (clopidogrel, prasugrel, and warfarin) were not independently associated with GI bleeding. GI bleeding was independently associated with a significant increase in all-cause 30-day mortality (OR 2.08 [1.52-2.83]). Patients with in-hospital GI bleed who survived to 30-days had increased all-cause mortality risk at 1 year compared to non-bleeders (HR 1.49 [1.07-2.09]). CONCLUSIONS: In-hospital GI bleeding following PCI is rare but is a clinically important event associated with increased 30-day and long-term mortality.

BACKGROUND: Mineralocorticoid receptor antagonist (MRA) therapy has been shown to prevent adverse left ventricular (LV) remodeling in ST-segment elevation myocardial infarction (STEMI) patients with heart failure. Whether initiating MRA therapy prior to primary percutaneous coronary intervention (PPCI) accrues additional benefit of reducing myocardial infarct size and preventing adverse LV remodeling is not known. We aimed to investigate whether MRA therapy initiated prior to reperfusion reduces myocardial infarct (MI) size and prevents adverse LV remodeling in STEMI patients. METHODS: STEMI patients presenting within 12 hours and with a proximal coronary artery occlusion with Thrombolysis In Myocardial Infarction flow grade 0 were consented and randomized to either an intravenous bolus of potassium canrenoate, followed by oral spironolactone for 3 months or matching placebo. The primary endpoint was MI size by cardiovascular magnetic resonance at 3 months. RESULTS: Sixty-seven patients completed the study. There was no significant difference in the final MI size at 3 months between the 2 groups (placebo: 17 ± 11%, MRA: 16 ± 10%, P = .574). There was also no difference in acute MI size (26 ± 16% versus 23 ± 14%, P = .425) or myocardial salvage (26 ± 12% versus 24 ± 8%, P = .456). At follow-up, there was a trend towards an improvement in LVEF (placebo: 49 ± 8%, MRA: 54 ± 11%, P = .053), and the MRA group had significantly greater percentage decrease in LVEDV (mean difference: -12.2 (95% CI -20.3 to -4.4)%, P = .003) and LVESV (mean difference: -18.2 (95% CI -30.1 to -6.3)%, P = .003). CONCLUSION: This pilot study showed no benefit of MRA therapy in reducing MI size in STEMI patients when initiated prior to reperfusion, but there was an improvement in LV remodeling at 3 months. Adequately powered studies are warranted to confirm these findings.

AIMS: Access site choice for cases requiring rotational atherectomy (PCI-ROTA) is poorly defined. Using the British Cardiovascular Intervention Society PCI database, temporal changes and contemporary associates/outcomes of access site choice for PCI-ROTA were studied. METHODS AND RESULTS: Data were analysed from 11,444 PCI-ROTA procedures performed in England and Wales between 2007 and 2014. Multivariate logistic regression was used to identify predictors of access site choice and its association with outcomes. RESULTS: For PCI-ROTA, radial access increased from 19.6% in 2007 to 58.6% in 2014. Adoption of radial access was slower in females, those with prior CABG, and in patients with chronic occlusive (CTO) or left main disease. In 2013/14, the strongest predictors of femoral artery use were age (OR 1.02, [1.005-1.036], P = .008), CTO intervention (OR 1.95, [1.209-3.314], P = .006), and history of previous CABG (OR 1.68, [1.124-2.515], P = .010). Radial access was associated with reductions in overall length of stay, and increased rates of same-day discharge. Procedural success rates were similar although femoral access use was associated with increased access site complications (2.4 vs. 0.1%, P < .001). After adjustment for baseline differences, arterial complications (OR 15.6, P < .001), transfusion (OR 12.5, P = .023) and major bleeding OR 6.0, P < .001) remained more common with FA use. Adjusted mortality and MACE rates were similar in both groups. CONCLUSIONS: In contemporary practice, radial access for PCI-ROTA results in similar procedural success when compared to femoral access but is associated with shorter length of stay, and lower rates of vascular complication, major bleeding and transfusion.

OBJECTIVE: This study aims to evaluate outcomes associated with different P2Y12 agents in Saphenous Vein graft (SVG) percutaneous coronary intervention (PCI). BACKGROUND: SVG PCI is associated with greater risks of ischemic complications, compared with native coronary PCI. Outcomes associated with the use of potent P2Y12 blocking drugs, Prasugrel and Ticagrelor, in SVG PCI are unknown. METHODS: Patients included in the study underwent SVG PCI in the United Kingdom between 2007 and 2014 for acute coronary syndrome and were grouped by P2Y12 antiplatelet use. In-hospital major adverse cardiac events, major bleeding and 30-day and 1-year mortality were examined. Multiple imputations with chained equations to impute missing data were used. Adjustment for baseline imbalances was performed using (1) multiple logistic regression (MLR) and (separately) (2) propensity score matching (PSM). RESULTS: Data weres analyzed from 8,119 patients and most cases were treated with Clopidogrel (n = 7,401), followed by Ticagrelor (n = 497) and Prasugrel (n = 221). In both MLR and PSM models, there was no significant evidence to suggest that either Prasugrel or Ticagrelor was associated with significantly lower 30-day mortality compared with Clopidogrel. The odds ratios reported from the multivariable analysis were 1.22 (95% CI: 0.60-2.51) for Prasugrel vs. Clopidogrel and 0.48 (95% CI: 0.20-1.16) for Ticagrelor vs. Clopidogrel. No significant differences were seen for in-hospital ischemic or bleeding events. CONCLUSIONS: Our real world national study provides no clear evidence to indicate that use of potent P2Y12 blockers in SVG PCI is associated with improved clinical outcomes.

PURPOSE: To investigate the performance of T1 and T2 mapping to detect intramyocardial hemorrhage (IMH) in ST-segment elevation myocardial infarction (STEMI) patients treated by primary percutaneous coronary intervention (PPCI). MATERIALS AND METHODS: Fifty STEMI patients were prospectively recruited between August 2013 and July 2014 following informed consent. Forty-eight patients completed a 1.5T cardiac magnetic resonance imaging (MRI) with native T1 , T2 , and T2* maps at 4 ± 2 days. Receiver operating characteristic (ROC) analyses were performed to assess the performance of T1 and T2 to detect IMH. RESULTS: The mean age was 59 ± 13 years old and 88% (24/48) were male. In all, 39 patients had interpretable T2* maps and 26/39 (67%) of the patients had IMH ( T2* <20 msec on T2* maps). Both T1 and T2 values of the hypointense core within the area-at-risk (AAR) performed equally well to detect IMH (T1 maps AUC 0.86 [95% confidence interval [CI] 0.72-0.99] versus T2 maps AUC 0.86 [95% CI 0.74-0.99]; P = 0.94). Using the binary assessment of presence or absence of a hypointense core on the maps, the diagnostic performance of T1 and T2 remained equally good (T1 AUC 0.87 [95% CI 0.73-1.00] versus T2 AUC 0.85 [95% CI 0.71-0.99]; P = 0.90) with good sensitivity and specificity (T1 : 88% and 85% and T2 : 85% and 85%, respectively). CONCLUSION: The presence of a hypointense core on the T1 and T2 maps can detect IMH equally well and with good sensitivity and specificity in reperfused STEMI patients and could be used as an alternative when T2* images are not acquired or are not interpretable.

BACKGROUND: A comprehensive cardiovascular magnetic resonance (CMR) in reperfused ST-segment myocardial infarction (STEMI) patients can be challenging to perform and can be time-consuming. We aimed to investigate whether native T1-mapping can accurately delineate the edema-based area-at-risk (AAR) and post-contrast T1-mapping and synthetic late gadolinium (LGE) images can quantify MI size at 1.5 T. Conventional LGE imaging and T2-mapping could then be omitted, thereby shortening the scan duration. METHODS: Twenty-eight STEMI patients underwent a CMR scan at 1.5 T, 3 ± 1 days following primary percutaneous coronary intervention. The AAR was quantified using both native T1 and T2-mapping. MI size was quantified using conventional LGE, post-contrast T1-mapping and synthetic magnitude-reconstructed inversion recovery (MagIR) LGE and synthetic phase-sensitive inversion recovery (PSIR) LGE, derived from the post-contrast T1 maps. RESULTS: Native T1-mapping performed as well as T2-mapping in delineating the AAR (41.6 ± 11.9% of the left ventricle [% LV] versus 41.7 ± 12.2% LV, P = 0.72; R2 0.97; ICC 0.986 (0.969-0.993); bias -0.1 ± 4.2% LV). There were excellent correlation and inter-method agreement with no bias, between MI size by conventional LGE, synthetic MagIR LGE (bias 0.2 ± 2.2%LV, P = 0.35), synthetic PSIR LGE (bias 0.4 ± 2.2% LV, P = 0.060) and post-contrast T1-mapping (bias 0.3 ± 1.8% LV, P = 0.10). The mean scan duration was 58 ± 4 min. Not performing T2 mapping (6 ± 1 min) and conventional LGE (10 ± 1 min) would shorten the CMR study by 15-20 min. CONCLUSIONS: T1-mapping can accurately quantify both the edema-based AAR (using native T1 maps) and acute MI size (using post-contrast T1 maps) in STEMI patients without major cardiovascular risk factors. This approach would shorten the duration of a comprehensive CMR study without significantly compromising on data acquisition and would obviate the need to perform T2 maps and LGE imaging.

BACKGROUND: The assessment of post-myocardial infarction (MI) left ventricular (LV) remodeling by cardiovascular magnetic resonance (CMR) currently uses criteria defined by echocardiography. Our aim was to provide CMR criteria for assessing LV remodeling following acute MI. METHODS: Firstly, 40 reperfused ST-segment elevation myocardial infarction (STEMI) patients with paired acute (4 ± 2 days) and follow-up (5 ± 2 months) CMR scans were analyzed by 2 independent reviewers and the minimal detectable changes (MDCs) for percentage change in LV end-diastolic volume (%ΔLVEDV), LV end-systolic volume (%ΔLVESV), and LV ejection fraction (%ΔLVEF) between the acute and follow-up scans were determined. Secondly, in 146 reperfused STEMI patients, receiver operator characteristic curve analyses for predicting LVEF <50% at follow-up (as a surrogate for clinical poor clinical outcome) were undertaken to obtain cut-off values for %ΔLVEDV and %ΔLVESV. RESULTS: The MDCs for %ΔLVEDV, %ΔLVESV, and %ΔLVEF were similar at 12%, 12%, 13%, respectively. The cut-off values for predicting LVEF < 50% at follow-up were 11% for %ΔLVEDV on receiver operating characteristic curve analysis (area under the curve (AUC) 0.75, 95% CI 0.6 to 0.83, sensitivity 72% specificity 70%), and 5% for %ΔLVESV (AUC 0.83, 95% CI 0.77 to 0.90, sensitivity and specificity 78%). Using cut-off MDC values (higher than the clinically important cut-off values) of 12% for both %ΔLVEDV and %ΔLVESV, 4 main patterns of LV remodeling were identified in our cohort: reverse LV remodeling (LVEF predominantly improved); no LV remodeling (LVEF predominantly unchanged); adverse LV remodeling with compensation (LVEF predominantly improved); and adverse LV remodeling (LVEF unchanged or worsened). CONCLUSIONS: The MDCs for %ΔLVEDV and %ΔLVESV between the acute and follow-up CMR scans of 12% each may be used to define adverse or reverse LV remodeling post-STEMI. The MDC for %ΔLVEF of 13%, relative to baseline, provides the minimal effect size required for investigating treatments aimed at improving LVEF following acute STEMI.

AIMS: The HORIZONS trial reported a survival advantage for bivalirudin over heparin-with-glycoprotein inhibitors (GPIs) in primary PCI for ST elevation myocardial infarction. This drove an international shift in clinical practice. Subsequent studies have produced divergent findings on mortality benefits with bivalirudin. We investigated this issue in a larger population than studied in any of these trials, using the United Kingdom national PCI registry. METHODS AND RESULTS: 61 136 primary PCI procedures were performed between January 2008 and January 2012. Demographic and procedural data were obtained from the registry. Mortality information was obtained through the UK Office of National Statistics. Multivariable logistic regression and propensity analysis modelling were utilized to study the association of different anti-thrombotic strategies with outcomes. Unadjusted data demonstrated near-identical survival curves for bivalirudin and heparin-plus-GPI groups. Significantly higher early and late mortality was found in patients treated with heparin alone ( ITALIC! P < 0.0001) but this group had a markedly higher baseline risk. After propensity matching, the bivalirudin vs. heparin-plus-GPI groups still demonstrated very similar adjusted mortality (odds ratio 1.00 at 30 days, and 0.96 at 1 year). Patients treated with heparin alone continued to show higher mortality after adjustment, although effect size was considerably diminished (odds ratio vs. other groups 1.17-1.24 at 30 days). CONCLUSIONS: Analysis of recent UK data showed no significant difference in short- or medium-term mortality between ST elevation myocardial infarction patients treated with bivalirudin vs. heparin-plus-GPI at primary PCI.

BACKGROUND: Stroke is a rare but potentially catastrophic complication of cardiac catheterization. Although some procedural aspects are known to influence stroke risk, the impact of radial versus femoral access site use is unclear. Early observational studies and limited randomized trial data suggested more frequent embolic events with radial access. Subsequently, larger pooled analyses have shown no clear differences in stroke risk but were limited by low event rates. Recent publication of relevant new data prompted our reevaluation of this concern. Therefore, we conducted a systematic review and meta-analysis to evaluate stroke complicating cardiac catheterization with use of transradial versus transfemoral access. METHODS AND RESULTS: A search of MEDLINE and EMBASE was undertaken using OVID SP with appropriate search terms. RevMan 5.3.5 was used to conduct a random-effects meta-analysis using the inverse variance method for pooling risk ratios (RRs) or the Mantel-Haenszel method for pooling dichotomous data. Pooled data from >24,000 patients in randomized controlled trials and >475,000 patients from observational studies were used. The risk ratio (RR) for (any) stroke, using randomized controlled trial data, was not significant (RR 0.87, 95% CI 0.58-1.29). Using observational data, a significant difference favoring radial access was seen (RR 0.71, 95% CI 0.52-0.98). CONCLUSIONS: Radial access site utilization for cardiac catheterization is not associated with an increased risk of stroke events. These data provide reassurance and should remove another potential barrier to conversion to a "default" radial practice among those who are currently predominantly femoral operators.

BACKGROUND: Over the past decade, major society guidelines have recommended the use of newer P2Y12 inhibitors over clopidogrel for those undergoing percutaneous coronary intervention for acute coronary syndrome. It is unclear what impact these recommendations had on clinical practice. METHODS AND RESULTS: All percutaneous coronary intervention procedures (n=534 210) for acute coronary syndrome in England and Wales (April 1, 2010, to March 31, 2022) were retrospectively analyzed, stratified by choice of preprocedural P2Y12 inhibitor (clopidogrel, ticagrelor, and prasugrel). Multivariable logistic regression models were used to examine odds ratios of receipt of ticagrelor and prasugrel (versus clopidogrel) over time, and predictors of their receipt. Overall, there was a significant increase in receipt of newer P2Y12 inhibitors from 2010 to 2020 (2022 versus 2010: ticagrelor odds ratio, 8.12 [95% CI, 7.67-8.60]; prasugrel odds ratio, 6.14 [95% CI, 5.53-6.81]), more so in ST-segment-elevation myocardial infarction than non-ST-segment-elevation acute coronary syndrome indication. The most significant increase in odds of receipt of prasugrel was observed between 2020 and 2022 (P<0.001), following a decline/plateau in its use in earlier years (2011-2019). In contrast, the odds of receipt of ticagrelor significantly increased in earlier years (2012-2017, Ptrend<0.001), after which the trend was stable (Ptrend=0.093). CONCLUSIONS: Over a 13-year-period, there has been a significant increase in use of newer P2Y12 inhibitors, although uptake of prasugrel use remained significantly lower than ticagrelor. Earlier society guidelines (pre-2017) were associated with the highest rates of ticagrelor use for non-ST-segment-elevation acute coronary syndrome and ST-segment-elevation myocardial infarction cases while the ISAR-REACT 5 (Prospective, Randomized Trial of Ticagrelor Versus Prasugrel in Patients With Acute Coronary Syndrome) trial and later society guidelines were associated with higher prasugrel use, mainly for ST-segment-elevation myocardial infarction indication.

BACKGROUND: There are limited data on the outcomes of percutaneous coronary intervention (PCI) following stent thrombosis (ST) and differences exist based on timing. AIMS: Our aim was to study the rates of PCI procedures for an ST indication among all patients admitted for PCI at a national level and to compare their characteristics and procedural outcomes based on ST timing. METHODS: All PCI procedures in England and Wales (2014-2020) were retrospectively analysed and stratified by the presence of ST into four groups: non-ST, early ST (0-30 days), late ST (>30-360 days), very late ST (>360 days). Multivariable logistic regression models were performed to assess the odds ratios (OR) of in-hospital MACCE (major adverse cardiovascular and cerebrovascular events, a composite of mortality, acute stroke and reinfarction) and mortality. RESULTS: Overall, 7,923 (1.4%) procedures were for ST indication, most commonly for early ST (n=4,171; 52.6%), followed by very late ST (n=2,801; 35.4%) and late ST (n=951; 12.0%). The rate of PCI for ST declined between 2014 and 2020 (1.7 to 1.4%; p<0.001). Early ST was the only subgroup associated with increased odds of MACCE (OR 1.22, 95% CI: 1.05-1.41), all-cause mortality (OR 1.21, 95% CI: 1.07-1.36) and reinfarction (OR 2.48, 95% CI: 1.48-4.14), compared with non-ST indication. The odds of mortality were significantly reduced in ST patients with the use of intravascular imaging (OR 0.66, 95% CI: 0.48-0.92) and newer P2Y12 inhibitors (ticagrelor: OR 0.69, 95% CI: 0.49-0.95; prasugrel: OR 0.54, 95% CI: 0.30-0.96). CONCLUSIONS: PCI for ST has declined in frequency over a 7-year period, with most procedures performed for early ST. Among the different times of ST onset, only early ST is associated with worse clinical outcomes after PCI. Routine use of intravascular imaging and newer P2Y12 inhibitors could further improve outcomes in this high-risk procedural group.

BACKGROUND: Fibrinolysis remains an important treatment for ST-elevation myocardial infarction, but fails to achieve adequate reperfusion in a significant proportion of cases. "Rescue" angioplasty is seen as the preferred treatment strategy in most contemporary centers although the literature provides conflicting evidence. METHODS: We retrospectively reviewed all cases of rescue angioplasty performed at our cardiothoracic center from July 1999 to June 2008. The diagnosis of failed lysis was made on the basis of an ECG demonstrating failure of ST segment resolution >50% at 90 min. Periprocedural data was taken from a dedicated procedural database and mortality data obtained from the UK Office of National Statistics. RESULTS: A total of 316 cases were performed. Patients were aged 61 ± 11 years. Thirty-day mortality was 8.9%. Thirty-day mortality in those presenting with cardiogenic shock was 50%, and in those requiring blood transfusion was also 50%. Thirty day mortality in those with TIMI III flow at the end of the procedure was significantly less than in those in whom this was not the case (6.6% vs. 23.3%; P < 0.001). One year mortality for the entire cohort was 10.1%. Longer-term follow-up revealed after 5.2 ± 2.3 years, survival in this cohort was 83%. Significant bleeding requiring blood transfusion occurred in 2.5% of cases. CONCLUSIONS: We have shown that rescue angioplasty can be performed with good procedural success rates and excellent long-term results. Limiting bleeding complications and achieving TIMI III flow appear to be major determinants of achieving good long term results.

This study aims to evaluate the temporal changes in DAPT score and determine whether there is an association between DAPT score and mortality. We analyzed all patients who underwent PCI in England and Wales 2007-2014. Statistical analyses were performed evaluating the DAPT score according to ≥2 and <2 cutoffs. Trends in DAPT score and logistic regressions were used to determine the association between DAPT score and 30 day, 1 year and 3 year mortality. A total of 243,440 patients were included in the analysis and the proportion of patients with DAPT score ≥ 2 was 35.6% (n = 86,550). The trend in DAPT score ≥ 2 showed an overall decline over time from 38.5% in 2007 to 34.5% in 2014. In more recent years, patients were older and a greater proportion were diabetic and had myocardial infarction on presentation and there was a significant decline in patients receiving paclitaxel stent (23.7% in 2007 to 0.2% in 2014). Patients with DAPT score ≥ 2 were more likely to be male, have previous CABG and have glycoprotein IIB/IIIa inhibitors. At 3 year follow up there was a significant difference in death compared DAPT ≥ 2 vs <2 (5.2% vs 5.5%, p < 0.001). DAPT score ≥ 2 was associated with reduced mortality at 1 year (OR 0.87 95%CI 0.82-0.92, p < 0.001) and 3 years (OR 0.82 95%CI 0.79-0.86, p < 0.001) after adjustments. These findings suggest that the DAPT score classifies 1 in 3 patients as having scores ≥2 and these patients have reduced odds of long-term mortality.

There is limited national data regarding emergency cardiac surgery for complications sustained after percutaneous coronary intervention (PCI). This study aimed to examine emergency cardiac surgery after PCI in England and Wales and postsurgical patient outcomes. We analyzed patients in the British Cardiovascular Intervention Society database who underwent PCI between 2007 and 2014 and compared characteristics and outcomes for patients with and without emergency cardiac surgery. A total of 549,303 patients were included in the analysis and 362 (0.07%) underwent emergency cardiac surgery. There was a modest decline in the annual rate of emergency cardiac surgery from 0.09% to 0.06% between 2007 and 2014. Variables associated with emergency cardiac surgery included receipt of circulatory support (Odds ratio (OR) 39.20 95% confidence interval (CI) 27.75 to 55.36), aortic dissection (OR 28.39 95%CI 14.59 to 55.26), coronary dissection (OR 18.50 95%CI 13.60 to 25.18), coronary perforation (OR 7.86 95%CI 4.27 to 14.46), cardiac tamponade (OR 6.77 95%CI 3.13 to 14.66), and on-site surgical cover (OR 2.15 95%CI 1.56 to 2.97). After adjustments, patients with emergency cardiac surgery were at increased odds of 30-day mortality (OR 4.41 95%CI 2.94 to 6.62) and in-hospital major adverse cardiac and cerebrovascular events (OR 1.63 95%CI 1.07 to 2.48). On site surgical cover was independently associated with increased odds of mortality (OR 1.26 95%CI 1.20 to 1.33) following emergency cardiac surgery. In conclusion, emergency cardiac surgery after PCI is a rarely required procedure and in England and Wales there appears to be a decline in recent years. Patients who underwent emergency cardiac surgery have higher risk of adverse outcomes and longer length of hospital stay.

BACKGROUND: The evidence base for coronary perforation occurring during percutaneous coronary intervention in patients presenting with an acute coronary syndrome (ACS-PCI) is limited and the specific role of acute pharmacology in its clinical presentation unclear. METHODS AND RESULTS: Using the BCIS PCI database, data were analysed on all ACS-PCI procedures performed in England and Wales between 2007 and 2014. Multiple regressions were used to identify predictors of coronary perforation and its association with outcomes. Propensity score matching was used to evaluate the association between differing P2Y12 inhibitors or glycoprotein inhibitors (GPI) and CP. During 270,329 ACS-PCI procedures, 1013 coronary perforations were recorded (0.37%) with a stable annual incidence. In multiple regression analysis, covariates associated with increased frequency of coronary perforation included age, female gender, CTO intervention, number and length of stents used, and rotational atherectomy use, whilst differing P2Y12 inhibitors were not predictive. Using propensity score matching, use of a GPI was independently associated with tamponade (OR 1.50, [1.08-2.06], pâ¯=â¯0.014). The adjusted odds ratios for all clinical outcomes were adversely affected by coronary perforation. CONCLUSIONS: Coronary perforation is an infrequent event during ACS-PCI but is closely associated with adverse clinical outcomes. GPI use was associated with higher rates of tamponade.

OBJECTIVES: The authors used the British Cardiovascular Intervention Society (BCIS) national percutaneous coronary intervention (PCI) database to explore temporal changes in the use of intravascular imaging for unprotected left main stem PCI (uLMS PCI), defined the associates of imaging use, and correlate clinical outcomes including survival with imaging use. BACKGROUND: Limited registry data support the use of intravascular imaging during uLMS PCI to improve outcomes. METHODS: Data were analyzed from 11,264 uLMS PCI procedures performed in England and Wales between 2007 and 2014. Multivariate logistic regression was used to identify associates of imaging use. Propensity matching created 5,056 pairs of subjects with and without imaging and logistic regression was performed to quantify the association between imaging and outcomes. Multivariate logistic regression to identify the independent predictors of 12-month mortality was performed. RESULTS: Imaging use increased from 30.2% in 2007 to 50.2% in 2014 (p for trend < 0.001). The factors associated with imaging use included stable angina presentation (odds ratio [OR]: 1.200; 95% confidence interval [CI]: 1.147 to 1.246; p < 0.001), bifurcation LMS disease (OR: 1.220; 95% CI: 1.140 to 1.300; p < 0.001), previous PCI (OR: 1.320; 95% CI: 1.200 to 1.440; p < 0.001), and radial access (OR: 1.266; 95% CI: 1.217 to 1.317; p < 0.001). A lower rate of coronary complications, lower in-hospital major adverse cardiac events (OR: 0.470; 95% CI: 0.37 to 0.590; p < 0.001), and improved 30-day (OR: 0.540; 95% CI: 0.430 to 0.680; p < 0.001) and 12-month (OR: 0.660; 95% CI: 0.570 to 0.770; p < 0.001) mortality were observed with imaging use compared with no imaging use. Greater mortality reductions were observed with higher operator LMS PCI volume. In logistic regression modeling, imaging use was associated with improved 12-month survival. CONCLUSIONS: The observed lower mortality with use of intravascular imaging to guide uLMS PCI justifies the undertaking of a large-scale randomized trial.

This study examines a national cohort of patients with a diagnosis of acute coronary syndrome (ACS) for the prevalence of frailty, temporal changes over time, and its association with treatments and clinical outcomes. The National Inpatient Sample database was used to identify US adults with a diagnosis of ACS between 2004 and 2014. Frailty risk was determined using a validated Hospital Frailty Risk Score based on ICD-9 codes using the cutoffs <5, 5 to 15, and >15 for low- (LRS), intermediate- (IRS), and high-risk (HRS) frailty scores, respectively. Logistic regression assessed associations of frailty with clinical outcomes, adjusted for patient co-morbidities and hospital characteristics. From 7,398,572 hospital admissions with ACS between 2004 and 2014, 86.5% of patients had LRS, 13.4% had an IRS, and 0.1% had an HRS. From 2004 to 2014, the prevalence of IRS and HRS patients increased from 8.1% to 18.2% and 0.03% to 0.18%, respectively (p <0.001 for both). The proportion of patients treated with percutaneous coronary intervention was greatest among patients with lowest frailty risk scores (LRS 42.9%, IRS 21.0%, and HRS 14.6%). Comparing HRS to LRS, there was a significant increase in bleeding complications (odds ratio [OR] 2.34, 95% confidence interval [CI] 2.03 to 2.69), vascular complications (OR 2.08, 95% CI 1.79 to 2.41), in-hospital stroke (OR 7.84, 95% CI 6.93 to 8.86), and in-hospital death (OR 2.57, 95% CI 2.18 to 3.04). Risk of frailty is common among patients with ACS, is increasing in prevalence, and is associated with differential management strategies, and outcomes during hospitalization. Increased awareness could facilitate frailty-tailored care to minimize the risk of adverse outcomes.
