RESUMO
BACKGROUND: Clinical outcomes of patients presenting with STEMI are significantly improved by reducing time from vessel occlusion to coronary blood flow restoration. In an effort to improve outcomes, we developed a secure mobile application, STEMIcathAID, and designed a pilot project implementing the app into the workflow for STEMI patients transfer. The aim of the study is to assess the impact of the app on key metrics for STEMI transfer before (historic) and after app launch. METHODS: The pilot project included physicians, nurses and technicians from the Emergency Medicine and Nursing Departments at the referring center, the catheterization laboratory and transfer center. From July 2021 to February 2023, the referring center activated STEMIcathAID alarms in parallel with the previously established STEMI activation with traditional phone call to transfer center. RESULTS: One hundred eleven suspected STEMI calls were activated through the app with 66 accepted and 45 rejected cases; thirty-one STEMI cases with available device time were compared with 42 STEMIs activated through the traditional pathway before the app implementation. Median door-to-device time for STEMIcathAID-assisted transfer decreased from 106 to 86 min (p < 0.001). The significant improvement, 20 min (19%), of the key metric for interhospital transfer resulted in all STEMI cases meeting the AHA goal of door-to-device time ≤ 120 min. In addition, median door-in-door-out time at the referral hospital decreased from 56 to 50 min (p = 0.01). CONCLUSIONS: Implementation of a mobile app into STEMI workflow of a large urban healthcare system significantly improved the quality of care for transfer of STEMI patients. TRIAL REGISTRATION: AHA Get With The Guidelines-Coronary Artery Disease® (GWTG-CAD) registry is a national quality improvement program and is not subject to the institutional review board approval.
RESUMO
BACKGROUND: Diabetes mellitus (DM) is a modifiable risk factor for patients with coronary artery disease (CAD). Treatment with insulin correlates with advanced disease and has been associated with excess cardiovascular risk, but evidence on outcomes of patients with insulin-treated DM (ITDM) undergoing left main percutaneous coronary intervention (LMPCI) remains scarce. AIMS: The aim of the presented study is to evluate the risk attributable to DM and ITDM in patients undergoing LMPCI. METHODS: We included 869 patients undergoing PCI for unprotected LMCAD. The cohort was divided into three subgroups based on diabetic status: No DM, ITDM, and Non-ITDM. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of death, spontaneous myocardial infarction (MI), or stroke at 1 year. Results were adjusted for clinically relevant baseline characteristics. RESULTS: Amongst participants, 58.7% had no DM, 25.9% non-ITDM, and 15.4% ITDM. Diabetics were younger and more likely to be female. They also exhibited higher body mass index as well as prevalence of comorbidities, including hypertension, anemia, and chronic kidney disease. The number of bifurcation lesions and stents used was similar between groups. At 1 year, when compared to no DM, ITDM (25.4% vs. 10.0%, p < 0.01) but not non-ITDM (10.8% vs. 10.0%, p = 0.94) demonstrated higher MACCE. This finding was driven by increased risk of MI. Mortality was 8.4%, 7.8%, and 17.2% for no DM, Non-ITDM, and ITDM, respectively. Results remained unchanged after adjustment. CONCLUSIONS: In a rather contemporary patient population undergoing PCI for LMCAD, ITDM but not non-ITDM was associated with higher risk of 1-year MACCE, primarily driven by MI.
RESUMO
BACKGROUND: It remains unclear whether procedural myocardial infarction (pMI) and spontaneous myocardial infarction (spMI) have a similar impact on prognosis. OBJECTIVES: The aim of this study was to assess mortality after pMI and spMI. METHODS: Patients with chronic coronary syndrome (CCS) and baseline troponin ≤1× the upper reference level (URL) or with acute spMI who underwent percutaneous coronary intervention (PCI) were included. PMI was defined as post-PCI troponin increase >1× URL in patients with CCS. SpMI comprised any acute coronary syndrome with elevated troponin. The 1-year risk of all-cause death was assessed after pMI and spMI across 3 strata of troponin elevation (>1-5×, >5-35×, and >35× URL), with CCS patients having post-PCI troponin ≤1× URL as a reference group. Conventional troponin I was measured using the Architect methodology (Abbott). RESULTS: Among 10,707 patients undergoing PCI from 2012 to 2020, 8,515 patients presented with CCS and 2,192 with spMI. Among CCS patients, 913 (10.7%) had pMI. Troponin peaks >1-5×, >5-35×, and >35× URL were observed in 53%, 41%, and 6% of patients with pMI, and in 24%, 38%, and 37% of patients with spMI, respectively. Mortality at 1 year was higher after pMI (7.7%; adjusted HR: 4.40; 95% CI: 1.59-12.2), and spMI (8.5%; adjusted HR: 7.57; 95% CI: 5.44-10.5) with troponin peak >35× URL compared with no-MI (1.4%). Mortality was also increased after spMI with troponin peak >1-5× or >5-35× URL. CONCLUSIONS: Mortality at 1 year was significantly increased after pMI and spMI with troponin peak >35× URL, whereas for troponin levels ≤35× only spMI had a relevant impact on mortality.

BACKGROUND: Individuals suffering from polyvascular atherosclerotic disease (PolyVD) face a higher likelihood of adverse cardiovascular events. Additionally, inflammation, assessed by high-sensitivity C-reactive protein (hsCRP), affects residual risk following percutaneous coronary intervention (PCI). We aimed to explore the interplay between PolyVD and hsCRP in terms of clinical outcomes after PCI. METHODS: Patients undergoing PCI for chronic coronary disease at a tertiary center between January 2012 and February 2020 were included for the current analysis. PolyVD was defined by additional history of cerebrovascular and/or peripheral artery disease. HsCRP levels were defined as elevated when the measured baseline concentration was > 3 mg/L. The primary outcome of interest was major adverse cardiovascular events (MACE), a composite of all-cause mortality, spontaneous MI, or target vessel revascularization. RESULTS: Overall, 10,359 participants were included in the current study, with 17.4% affected by PolyVD and 82.6% included in the non-PolyVD subgroup. Patients with PolyVD had higher hsCRP levels than those without. Among the PolyVD group, a larger proportion (33.6%) exhibited elevated hsCRP compared to the non-PolyVD group (24.7%). Patients with both PolyVD and elevated hsCRP levels had significantly higher adverse event rates than all other subgroups at 1-year follow-up. Furthermore, an independent association between elevated hsCRP and MACE was observed within the PolyVD population, while this was not the case for individuals without PolyVD. CONCLUSION: A residual risk of adverse outcomes after PCI linked to inflammation appears to be present among individuals with PolyVD. This could help define further target populations for anti-inflammatory treatment options.
RESUMO
BACKGROUND: Patients may prefer percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery, despite heart team recommendations. The outcomes in such patients have not been examined. We sought to examine the results of PCI in patients who were recommended for but declined CABG. METHODS AND RESULTS: Consecutive patients with stable ischemic heart disease and unprotected left main or 3-vessel disease or Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score >22 who underwent PCI after heart team review between 2013 and 2020 were included. Patients were categorized into 3 groups according to heart team recommendations on the basis of appropriate use criteria: (1) PCI-recommended; (2) CABG-eligible but refused CABG (CABG-refusal); and (3) CABG-ineligible. The primary end point was the composite of death, myocardial infarction, or stroke at 1 year. The study included 3687 patients undergoing PCI (PCI-recommended, n=1718 [46.6%]), CABG-refusal (n=1595 [43.3%]), and CABG-ineligible (n=374 [10.1%]). Clinical and procedural risk increased across the 3 groups, with the highest comorbidity burden in CABG-ineligible patients. Composite events within 1 year after PCI occurred in 55 (4.1%), 91 (7.0%), and 41 (14.8%) of patients in the PCI-recommended, CABG-refusal, and CABG-ineligible groups, respectively. After multivariable adjustment, the risk of the primary composite outcome was significantly higher in the CABG-refusal (hazard ratio [HR], 1.67 [95% CI, 1.08-3.56]; P=0.02) and CABG-ineligible patients (HR, 3.26 [95% CI, 1.28-3.65]; P=0.004) groups compared with the reference PCI-recommended group, driven by increased death and stroke. CONCLUSIONS: Cardiovascular event rates after PCI were significantly higher in patients with multivessel disease who declined or were ineligible for CABG. Our findings provide real-world data to inform shared decision-making discussions.

Percutaneous coronary intervention (PCI) has demonstrated its safety and efficacy in treating left main (LM) coronary artery disease (CAD) in select patients. Polyvascular disease (PolyVD) is associated with adverse events in all-comers with CAD. However, there is little data examining the interplay between PolyVD and LM-PCI, which we sought to investigate in a retrospective single-center study. We included patients who underwent unprotected LM-PCI at a tertiary center from 2012 to 2019. The study population was stratified based on the presence or absence of PolyVD (i.e., medical history of cerebrovascular and/or peripheral artery disease in addition to LM-CAD). The primary outcome was major adverse cardiovascular events (MACE) combining all-cause mortality and spontaneous myocardial infarction within 1 year after index PCI. Overall, 869 patients were included, and 23.8% of the population had PolyVD. Subjects with PolyVD were older and had a greater burden of co-morbidities. After 1-year follow-up, PolyVD patients exhibited significantly higher rates of both MACE (22.8% vs 9.4%, p <0.001) and bleeding events compared with those without PolyVD. MACE was primarily driven by an increase in all-cause mortality (18.3% vs 7.1%, p <0.001). Results persisted after adjusting for confounders. In conclusion, in patients who underwent LM-PCI, the presence of PolyVD is linked to an increased risk of MACE and bleeding after 1 year of follow-up, which highlights the vulnerability of this population.

Angina with nonobstructive coronary arteries (ANOCA) is increasingly recognized and may affect nearly one-half of patients undergoing invasive coronary angiography for suspected ischemic heart disease. This working diagnosis encompasses coronary microvascular dysfunction, microvascular and epicardial spasm, myocardial bridging, and other occult coronary abnormalities. Patients with ANOCA often face a high burden of symptoms and may experience repeated presentations to multiple medical providers before receiving a diagnosis. Given the challenges of establishing a diagnosis, patients with ANOCA frequently experience invalidation and recidivism, possibly leading to anxiety and depression. Advances in scientific knowledge and diagnostic testing now allow for routine evaluation of ANOCA noninvasively and in the cardiac catheterization laboratory with coronary function testing (CFT). CFT includes diagnostic coronary angiography, assessment of coronary flow reserve and microcirculatory resistance, provocative testing for endothelial dysfunction and coronary vasospasm, and intravascular imaging for identification of myocardial bridging, with hemodynamic assessment as needed.

Centers specializing in coronary function testing are critical to ensure a systematic approach to the diagnosis and treatment of angina with nonobstructive coronary arteries (ANOCA). Management leveraging lifestyle, pharmacology, and device-based therapeutic options for ANOCA can improve angina burden and quality of life in affected patients. Multidisciplinary care teams that can tailor and titrate therapies based on individual patient needs are critical to the success of comprehensive programs. As coronary function testing for ANOCA is more widely adopted, collaborative research initiatives will be fundamental to improve ANOCA care. These efforts will require standardized symptom assessments and data collection, which will propel future large-scale clinical trials.

Rotational atherectomy (RA) is widely used in the percutaneous treatment of heavily calcified coronary artery lesions in patients with chronic coronary syndromes (CCS). However, the safety and efficacy of RA in acute coronary syndrome (ACS) is not well established and is considered a relative contraindication. Therefore, we sought to evaluate the efficacy and safety of RA in patients presenting with non-ST-elevation myocardial infarction (NSTEMI), unstable angina (UA), and CCS. Consecutive patients who underwent percutaneous coronary intervention with RA between 2012 and 2019 at a tertiary single center were included. Patients presenting with ST-elevation myocardial infarction (MI) were excluded. The primary end points of interest were procedural success and procedural complications. The secondary end point was the risk of death or MI at 1 year. A total of 2,122 patients who underwent RA were included, of whom 1,271 presented with a CCS (59.9%), 632 presented with UA (29.8%), and 219 presented with NSTEMI (10.3%). Although an increased rate of slow-flow/no-reflow was noted in the UA population (p = 0.03), no significant difference in procedural success or procedural complications, including coronary dissection, perforation, or side-branch closure, was noted (p = NS). At 1 year, there were no significant differences in death or MI between CCS and non-ST-elevation ACS (NSTE-ACS: UA + NSTEMI; adjusted hazard ratio 1.39, 95% confidence interval 0.91 to 2.12); however, patients who presented with NSTEMI had a higher risk of death or MI than CCS (adjusted hazard ratio 1.79, 95% confidence interval 1.01 to 3.17). Use of RA in NSTE-ACS was associated with similar procedural success without an increased risk of procedural complications compared with patients with CCS. Although patients presenting with NSTEMI remained at higher risk of long-term adverse events, RA appears to be safe and feasible in patients with heavily calcified coronary lesions presenting with NSTE-ACS.

BACKGROUND: Data on the prognostic value of high-sensitivity C-reactive protein (hs-CRP) levels in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI) are limited. METHODS: Patients undergoing PCI at a tertiary center from January 2012 to December 2019 were included. CKD was defined as a glomerular filtration rate (GFR) <60â¯mL/min/1.73m2 and elevated hs-CRP was defined as >3â¯mg/L. Acute myocardial infarction (MI), acute heart failure, neoplastic disease, patients undergoing hemodialysis, or hs-CRP >10â¯mg/L were exclusion criteria. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, MI, and target vessel revascularization at 1-year after PCI. RESULTS: Out of 12,410 patients, 3029 (24.4â¯%) had CKD. Elevated hs-CRP levels were found in 31.8â¯% of CKD and 25.8â¯% of no-CKD patients. At 1â¯year, MACE occurred in 87 (11.0â¯%) CKD patients with elevated hs-CRP and 163 (9.5â¯%) with low hs-CRP (adj. HR 1.26, 95â¯% CI 0.94-1.68); among no-CKD patients, in 200 (10â¯%) and 470 (8.1â¯%), respectively (adj. HR 1.21, 95â¯% CI 1.00-1.45). Hs-CRP was associated with an increased risk of all-cause death in both CKD (Adj. HR 1.92, 95â¯% CI 1.07-3.44) and no-CKD patients (adj. HR 3.02, 95â¯% CI 1.74-5.22). There was no interaction between hs-CRP and CKD status. CONCLUSIONS: Among patients undergoing PCI without acute MI, elevated hs-CRP values were not associated with a higher risk of MACE at 1â¯year, but with increased mortality hazards consistently in patients with or without CKD.

BACKGROUND: The TWILIGHT trial (NCT02270242) demonstrated that in selected high-risk patients undergoing percutaneous coronary intervention (PCI) ticagrelor monotherapy significantly reduced bleeding complications without ischemic harm as compared to ticagrelor plus aspirin after 3-month of dual antiplatelet therapy. The aim of this analysis was to assess the applicability of the findings TWILIGHT trial to a real-world population. METHODS: Patients undergoing PCI at a tertiary center between 2012 and 2019 and not meeting any TWILIGHT exclusion criterion (oral anticoagulation treatment, ST-segment elevation myocardial infarction [MI], cardiogenic shock, dialysis, prior stroke, or thrombocytopenia) were included. Patients were stratified into 2 groups based on whether they fulfilled the TWILIGHT inclusion criteria (high-risk) or not (low-risk). The primary outcome was all-cause death; the key secondary outcomes were MI and major bleeding at 1 year after PCI. RESULTS: Out of 13,136 included patients, 11,018 (83%) were at high risk. At 1-year, these patients had an approximately 3 folds greater hazard of death (1.4% vs 0.4%, HR 3.63, 95% CI 1.70-7.77) and MI (1.8% vs 0.6%, HR 2.81, 95% CI 1.56-5.04) and a nearly 2 folds higher risk of major bleeding (3.3% vs 1.8%, HR 1.86, 95% CI 1.32-2.62) as compared to low-risk patients. CONCLUSION: Among patients not meeting the TWILIGHT exclusion criteria from a large PCI registry, the high-risk inclusion criteria of the TWILIGHT trial were met by the majority of patients and were associated with an increased risk of mortality and MI and a moderately elevated risk of bleeding.

BACKGROUND: Potent P2Y12 inhibitors such as ticagrelor and prasugrel are superior to clopidogrel in acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI). Whether this benefit extends to a patient population with chronic coronary syndromes (CCS) is unclear. AIMS: We sought to compare the safety and efficacy of prasugrel and ticagrelor versus clopidogrel in patients undergoing PCI for CCS. METHODS: Consecutive patients undergoing PCI for CCS at a tertiary centre between 2014 and 2019 who were discharged on prasugrel or ticagrelor were compared with those on clopidogrel. The primary endpoint was the composite of death and myocardial infarction (MI), with secondary outcomes including rates of bleeding, stroke, and target vessel revascularisation at 1 year. RESULTS: Overall, 11,508 patients were included in the study (ticagrelor/prasugrel n=2,860 [24.9%], clopidogrel n=8,648 [75.1%]) with an increasing frequency of potent P2Y12 inhibitor use over the study period (ptrend<0.001). Clopidogrel was used more frequently in patients with multimorbid risk factors, whereas anatomical or procedural complexity was associated with ticagrelor/prasugrel use (left main PCI, bifurcation PCI, number of lesions, rotational atherectomy). No difference in the incidence of death or MI was noted across the groups (ticagrelor/prasugrel vs clopidogrel: 2.7% vs 3.1%, adjusted hazard ratio [adjHR] 0.86, 95% confidence interval [CI]: 0.62-1.17; p=0.33) or secondary outcomes including bleeding (adjHR 0.75, 95% CI: 0.46-1.21; p=0.23) on propensity score stratification analysis. Additionally, no difference in the primary outcome was observed across subgroups, including those undergoing complex PCI. CONCLUSIONS: Ticagrelor and prasugrel are increasingly used in patients with CCS undergoing PCI with similar 1-year efficacy and safety when compared to clopidogrel. Whether use of these agents can be beneficial in patients undergoing PCI for CCS with a high thrombotic and low bleeding risk warrants further study.

BACKGROUND: Patients with chronic kidney disease (CKD) are at higher risk of ischemic and bleeding events after percutaneous coronary intervention (PCI). Complex PCI (CPCI) is associated with higher rates of ischemic complications. Whether CPCI confers an additive risk of adverse events in CKD patients is unclear. METHODS: Patients who underwent PCI at a single tertiary-care-center between 2012 and 2019 were stratified by CKD status and CPCI. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and target-vessel revascularization (TVR) at 1-year follow-up. Secondary outcomes included the individual components of the primary outcome and major bleeding. RESULTS: Out of 15,071 patients, 4537 (30.1%) had CKD and 10,534 (69.9%) had no CKD. Patients undergoing CPCI were 1151 (25.4%) and 2983 (28.3%) in the two cohorts, respectively. At one year, CPCI compared with no CPCI was associated with higher risk of MACE in both CKD (Adj. HR 1.72, 95% confidence interval [CI] 1.45-2.06, p < 0.001) and no-CKD patients (Adj. hazard ratios [HR] 2.19, 95% CI 1.91-2.51, p < 0.001; p of interaction 0.057), determined by an excess of death, MI and TVR in CKD patients and of TVR and MI only in no-CKD. CPCI was related with a consistent increase of major bleeding in the CKD (Adj. HR 1.49, 95% CI 1.18-1.87, p < 0.001) and no-CKD group (Adj. HR 1.23, 95% CI 0.98-1.54, p = 0.071, p of interaction 0.206). CONCLUSION: At 1-year follow-up, CPCI was associated with higher risk of MACE and major bleeding irrespective of concomitant CKD. CPCI predicted mortality in CKD patients only.

A universal definition to identify patients at higher risk of complications after percutaneous coronary intervention (PCI) is lacking. We aimed to validate a recently developed score to identify patients at increased risk of all-cause death after PCI. All consecutive patients from a large PCI registry not presenting with ST-elevation myocardial infarction or cardiogenic shock were included. Each patient was assigned a score obtained by summing the points associated with the following variables: age >80 years (3 points), dialysis (6 points), left ventricular ejection fraction <30% (2 points), and multivessel PCI (2 points). Patients were stratified in 3 groups: low risk (score 0), intermediate risk (score 2 to 3), or high risk (score ≥4). The primary outcome was all-cause death, and the secondary outcomes were major adverse cardiovascular events and major bleeding. Events were assessed at 1 year after PCI. Between January 2014 and December 2019, 12,689 patients underwent PCI. Compared with the 9,884 patients at low risk, those at intermediate and high risk had a fourfold (hazard ratio 3.99, 95% confidence interval 2.95 to 5.38) and ninefold (hazard ratio 9.55, 95% confidence interval 6.89 to 13.2) higher hazard for all-cause death at 1 year, respectively. The score had a good predictive value for all-cause death at 1 year (area under the curve 0.70). The risk of major adverse cardiovascular events and major bleeding increased consistently from the low- to the high-risk group. In conclusion, in patients who underwent PCI for stable ischemic heart disease or non-ST-elevation acute coronary syndrome, a score based on 4 variables well predicted the risk of all-cause death at 1 year.

BACKGROUND: Potent P2Y12 agents such as ticagrelor and prasugrel are increasingly utilized across the clinical spectrum of patients undergoing percutaneous coronary intervention (PCI). There is a paucity of data supporting their use in a patient population inclusive of both acute coronary syndrome (ACS) and chronic coronary syndrome (CCS) patients. OBJECTIVES: The authors compared the efficacy and safety of ticagrelor and prasugrel in a real-world contemporary PCI cohort. METHODS: Consecutive patients undergoing PCI between 2014 and 2019 discharged on either prasugrel or ticagrelor were included from the prospectively collected institutional PCI registry. Primary endpoint was the composite of death and myocardial infarction (MI), with secondary outcomes including rates of bleeding, stroke, and target vessel revascularization at 1 year. RESULTS: Overall, 3,858 patients were included in the study (ticagrelor: n = 2,771; prasugrel: n = 1,087), and a majority (48.4%) underwent PCI in the context of CCS. Patients prescribed ticagrelor were more likely to be female, have a history of cerebrovascular disease, and have ACS presentation, while those receiving prasugrel were more likely to be White with a higher prevalence of prior revascularization. No difference in the risk of death or MI was noted across the groups (ticagrelor vs prasugrel: 3.3% vs 3.1%; HR: 0.88; 95% CI: 0.54-1.43; P = 0.59). Rates of target vessel revascularization were significantly lower in the ticagrelor cohort (9.3% vs 14.0%; adjusted HR: 0.71; 95% CI: 0.55-0.91; P = 0.007) with no differences in stroke or bleeding. The results were consistent in patients with CCS (HR: 0.84; 95% CI: 0.46-1.54) and ACS (HR: 1.18; 95% CI: 0.46-1.54), without evidence of interaction (P = 0.37), and confirmed across multivariable adjustment and propensity score stratification analysis. CONCLUSIONS: In this contemporary patient population undergoing PCI, prasugrel and ticagrelor were associated with similar 1-year efficacy and safety.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is a high-risk patient medical emergency. We developed a secure mobile application, STEMIcathAID, to optimize care for STEMI patients by providing a digital platform for communication between the STEMI care team members, EKG transmission, cardiac catherization laboratory (cath lab) activation and ambulance tracking. The aim of this report is to describe the implementation of the app into the current STEMI workflow in preparation for a pilot project employing the app for inter-hospital STEMI transfer. APPROACH: App deployment involved key leadership stakeholders from all multidisciplinary teams taking care of STEMI patients. The team developed a transition plan addressing all aspects of the health system improvement process including the workflow analysis and redesign, app installation, personnel training including user account access to the app, and development of a quality assurance program for progress evaluation. The pilot will go live in the Emergency Department (ED) of one of the hospitals within the Mount Sinai Hospital System (MSHS) during the daytime weekday hours at the beginning and extending to 24/7 schedule over 4-6 weeks. For the duration of the pilot, ED personnel will combine the STEMIcathAID app activation with previous established STEMI activation processes through the MSHS Clinical Command Center (CCC) to ensure efficient and reliable response to a STEMI alert. More than 250 people were provisioned app accounts including ED Physicians and frontline nurses, and trained on their user-specific roles and responsibilities and scheduled in the app. The team will be provided with a feedback form that is discipline specific to complete after every STEMI case in order to collect information on user experience with the STEMIcathAID app functionality. The form will also provide quantitative metrics for the key time sensitive steps in STEMI care. CONCLUSIONS: We developed a uniform approach for deployment of a mobile application for STEMI activation and transfer in a large urban healthcare system to optimize the clinical workflow in STEMI care. The results of the pilot will demonstrate whether the app has a significant impact on the quality of care for transfer of STEMI patients.

BACKGROUND: There is a paucity of data on the prognostic value of high-sensitivity C-reactive protein (hsCRP) levels in diabetic and nondiabetic patients undergoing percutaneous coronary intervention (PCI). METHODS: All patients with known baseline hsCRP undergoing PCI at a single tertiary care centre from 2010 to 2017 were included. High hsCRP was defined as > 3 mg/L. Known causes of elevated hsCRP levels and hsCRP > 10 mg/L represented exclusion criteria. The 1-year primary outcome was major adverse cardiovascular events (MACE), including all-cause mortality, myocardial infarction (MI), and target-vessel revascularisation (TVR). RESULTS: Among a total of 11,979 patients included, high hsCRP levels were observed in 24.7% of patients without diabetes and 29.8% of patients with diabetes (P < 0.001). Both diabetics and nondiabetics with high hsCRP levels had increased rates of MACE compared with their counterparts with low hsCRP (diabetics: adjusted hazard ratio [aHR] 1.58, 95% CI 1.27-1.96; nondiabetics: aHR 1.45, 95% CI 1.13-1.86; P interaction = 0.981) primarily driven by increased rates all-cause deaths (diabetics: aHR 2.32, 95% CI 1.42-3.80; nondiabetics: aHR 3.14, 95% CI 1.74-5.65; P interaction = 0.415). Although high hsCRP levels were associated with increased rates of TVR (aHR 1.35, 95% CI 1.04-1.75) and MI (aHR 1.86, 95% CI 1.18-2.93) only in patients with diabetes, no significant interactions were observed between inflammation and diabetes (P interaction = 0.749 and 0.602, respectively). CONCLUSIONS: Patients undergoing PCI with high levels of hsCRP, defined as > 3 mg/L, have worse ischemic outcomes regardless of diabetes status.
