AbstractThe clinical efficacy of ticagrelor versus clopidogrel has not been replicated in East Asian populations. The pronounced bleeding risk with ticagrelor was of concern given the increased bleeding tendency in Asian populations. This study evaluated efficacy and safety of ticagrelor versus clopidogrel in patients with non-ST-elevation myocardial infarction (NSTEMI) in the entire Taiwan. We used the Taiwan National Health Insurance Research Database to identify 6203 patients aged ≥ 20 years with NSTEMI hospitalization and prescription of dual antiplatelets at discharge between January 2014 and December 2014. Cohorts of ticagrelor and clopidogrel were matched 1:1 based on propensity score matching to balance baseline covariates. The primary composite efficacy endpoints included death from any cause, non-fatal myocardial infarction, and non-fatal stroke. The secondary efficacy endpoints were the individual components. The primary safety endpoint was major bleeding requiring hospitalization. The incidence of primary efficacy endpoint was 20.3% in the ticagrelor users and 20.7% in the clopidogrel users (adjusted HR 0.94; 95% CI 0.73–1.22), with the median (interquartile range, IQR) follow-up period of 5.2 (2.3–8.5) months. The incidence of primary safety endpoint was 2.3% in the ticagrelor users and 3.2% in the clopidogrel users (adjusted HR 0.67; 95% CI 0.33–1.35). Regarding the secondary efficacy endpoint, patients treated with ticagrelor had significantly lower incidence of stroke (adjusted HR 0.44; 95% CI 0.21–0.94; p = 0.033). In this nationwide Taiwanese cohort of NSTEMI, treatment with ticagrelor after discharge, as compared to clopidogrel, had similar rates of ischemic composite events and major bleeding. Nevertheless, the median follow-up time was only 5.2 months, and the reduced stroke events with ticagrelor compared to clopidogrel needs further verification.

Abstract Background Elderly patients form a large and growing part of the patients presenting with non-ST-elevation myocardial infarction (NSTEMI). Choosing the optimal antithrombotic treatment in these elderly patients is more complicated because they frequently have characteristics indicating both a high ischaemic and high bleeding risk. Purpose We describe the treatment of elderly patients (>75 years) admitted with NSTEMI, present the outcomes (major adverse cardiovascular events (MACE) and bleeding) and aim to find predictors for adverse events. Methods The POPular AGE registry is an investigator initiated, prospective, observational, multicentre study of patients aged 75 years or older presenting with NSTEMI. Patients were recruited between August 1st, 2016 and May 7th, 2018 at 21 sites in the Netherlands. The primary composite endpoint of MACE included cardiovascular death, non-fatal myocardial infarction and non-fatal stroke at one-year follow-up. Results A total of 757 patients were enrolled. During hospital stay 76% underwent coronary angiography, 34% percutaneous coronary intervention and 12% coronary artery bypass grafting (CABG). At discharge 78.6% received aspirin (non-users mostly because of the combination of oral anticoagulant and clopidogrel), 49.7% were treated with clopidogrel, 34.2% with ticagrelor and 29.6% were prescribed oral anticoagulation. Eighty-three percent of patients received dual antiplatelet therapy (DAPT) or dual therapy consisting of oral anticoagulation and at least one antiplatelet agent for a duration of 12 months. At one year, the primary outcome of cardiovascular death, myocardial infarction or stroke occurred in 12.3% of patients and major bleeding (BARC 3 or 5) occurred in 4.8% of the patients. The risk of MACE and major bleeding was highest during the first month and stayed high over time for MACE while the risk for major bleeding levelled off. Independent predictors for MACE were age, renal function, medical history of CABG, stroke and diabetes. The only independent predictor for major bleeding was haemoglobin level on admission. Conclusion In this all-comers registry, most elderly patients (≥75 years) with NSTEMI are treated with DAPT and undergoing coronary angiography the same way as younger NSTEMI patients from the SWEDEHEART registry. Aspirin use was lower as was the use of the more potent P2Y12 inhibitors compared to the SWEDEHEART which is very likely due to the concomitant use of oral anticoagulation in 30% of patients. The fact that ischemic risk stays constant over 1 year of follow-up, while the bleeding risk levels off after one month may suggest the need of dual antiplatelet therapy until at least one year after NSTEMI.

Abstract Background Recent clinical study suggests newer-generation drug-eluting stents (DES) that combine ultrathin strut and nano-coating with biodegradable polymers sirolimus-eluting stent (BP-SES) could improve long-term clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over current generation DES. However, safety profiles in very early phase have not been systematically addressed. Objective and method We exploratory investigate early vascular response following BP-SES implantation in patients with STEMI to reveal mechanism of the favorable clinical outcomes in recent studies using frequency domain-optical coherence tomography (FD-OCT). Consecutive twenty patients with STEMI who underwent FD-OCT immediately after primary PCI and were eligible for follow-up FD-OCT at 2 weeks after implantation were enrolled between June 2018 and November 2019. Results Twenty patients (age 62.7±11.3 years, male 85.0%) were enrolled with frequencies of hypertension (45.0%), diabetes mellitus (35.0%), dyslipidemia (55.0%) and smoking (80.0%). Aspiration catheter were used in all patients, and 1.13±0.34 stents were used. Only one patient (5.0%) received chronic antiplatelet therapy with aspirin prior to the onset of STEMI. All patients started to receive prasugrel as thienopyridine from this event and continued dual antiplatelet therapy for 2 weeks. The percentage of uncovered struts significantly decreased from post-procedure to 2W follow-up (69±18% post-procedure versus 30±11% at 2W follow up, p<0.0001). Malapposed struts also decreased (5.6±5.7% post-procedure versus0.9±1.2% at 2W follow up, p<0.0001).The average protrusion area of athero-thrombotic burden numerically decreased (0.37±0.19 at post-procedure versus 0.34±0.14 mm2 at 2W follow up, p=0.19) and its volume showed similar tendency (10.60±6.40 at post-procedure versus 9.36±5.14 mm3 at 2W follow up, p=0.19). Conclusion(s) This study firstly elucidated very early vascular responses following ultrathin strut BP-SES implantation in STEMI patients, showing early progression of strut coverage and resolution of athero-thrombotic materials. This technology may have a potential to overcome the current generation DESs in this clinical setting. Thrombus, uncovered and malapposed struts Funding Acknowledgement Type of funding source: None

Background Randomized controlled trials indicate that acute ST elevation myocardial infarction (STEMI) patients have better clinical outcomes if rapid, complete and stable coronary artery patency can be achieved. The Queen Elizabeth II Health Sciences Center in Halifax, Nova Scotia (QEIIHSC) commenced a 24 hour PPCI program in November 2005. This real world study compares 2 year mortality in STEMI patients treated by PPCI versus patients treated by fibrinolysis with provisional rescue PCI within Nova Scotia, Canada. Methods This was a single center retrospective cohort study. All consecutive Nova Scotia, fibrinolytic and PPCI eligible STEMI patients presenting within 12 hours of symptom onset between July 1 st 2005 and June 30 th 2006 treated by PPCI at the QEIIHSC or fibrinolyis outside the QEIIHSC were included. The outcome measure was all cause mortality censored on June 30 th 2007. The crude and independent association between PPCI versus fibrinolysis on mortality was estimated using a Cox regression model. Results Data for 423 eligible patients (100% of cohort) comprised of 359/423 (85%) patients treated with fibrinolytics and 64/359 (18%) treated by PPCI were analyzed. The median follow-up was 1.4 years. The median (Q25 to Q75) door to needle times in the fibrinolytic group and corresponding door to balloon times in the PPCI group were: 0.5 (.3 to .9) and 1.5 (1.1 to 1.9) hours respectively. PPCI was associated with a consistent trend toward lower mortality versus fibrinolysis during hospitalization: 2/64 (3.1%) vs. 29/359 (8.1%), P=0.16 and at 30 days 2/64 (3.1%) vs. 32/359 (15%), P=0.12. This association was significant at 1 and 2 year follow-up: 2/64 (3.1%) vs. 41/359 (11%), P=0.043 and 2/64 (3.1%) vs. 45/359 (12%), P=0.027 respectively. This corresponded with an independent HR for 2 year mortality of: 0.1 (.01 to 0.8), p=0.03. Conclusion Initial data from the PPCI program at the QEIIHSC in Halifax, Nova Scotia indicates that PPCI was associated significant reductions in mortality versus fibrinolysis for real world patients presenting with STEMI. This mortality reduction was achieved in the early pilot phase of a PPCI program with evolving door to balloon timelines versus an established fibrinolytic program with acceptable door to needle timelines.

Abstract Background: Cysteine-rich angiogenic inducer 61 (Cyr61) is a matricellular protein participating in the angiogenesis, inflammation, and fibrotic tissue repair. Previous study has proven its value in diagnosing and risk stratification of ST-elevation myocardial infarction (STEMI). However, there is no study focusing on Cyr61 and the long-term outcome of STEMI. Methods: A total of 426 patients diagnosed with STEMI were enrolled in this study. Blood sample was acquired 24 hours after the admission. The patients were required long-term follow-up after the discharge, when primary endpoint of all-cause death and secondary endpoint of cardiac complications were observed. Cox hazard ratio model and survival analysis were used to compare the risk of patients with higher level and lower level of Cyr61. Results: We conducted an average of (48.4 ± 17.8) months of follow-up, during which a total of 28 deaths happened (6.6%), while 106 episodes of secondary endpoints occurred (24.9%). Patients with higher quartile (Q4) Cyr61 were at higher risk of death [HR 3.404 95%CI (1.574-7.360), P<0.001] when compared with lower three quartiles (Q1-Q3) Cyr61. In terms of secondary endpoints, patients with Q4 Cyr61 were subject to 4.718 [95%CI (3.189-6.978) , P<0.001] times of risk compared with Q1-Q3 Cyr61. Conclusions: For STEMI Patients, those with increased Cyr61 have higher risk of all-cause death and cardiac complications. Therefore, Cyr61 may be a useful tool in predicting the long-term prognosis of STEMI.

<b><i>Background:</i></b> In patients with ST-elevation myocardial infarction (STEMI), C-reactive protein (CRP) levels are associated with larger infarct size, transmural extent, and poor function of left ventricle and independently predict 30-day mortality. CRP-apheresis following STEMI showed to be feasible, safe, and has significant beneficial effect both on myocardial infarction size and wall motion. To the best of our knowledge, this is only the second published clinical evaluation of the efficacy and safety of selective CRP-apheresis in the STEMI treatment using Spectra-Optia and Pentrasorb CRP-adsorber systems. <b><i>Case Report:</i></b> A 53-year-old female was referred with anterior STEMI. After percutaneous coronary intervention, patient received standard post-STEMI therapy according to current guidelines. Selective therapeutic plasma exchange (TPE) was performed using Spectra-Optia (Terumo BCT; USA) and Pentrasorb CRP-adsorber (Pentracor GmbH; Germany) systems. Antecubital veins were used for vascular access and acid-citrate-dextrose solution (ACD formula A; total volume = 1,026 mL) was utilized as anticoagulant. The volume of processed blood was 15,600 mL. The removed “natural” plasma (total volume = 8,329 mL) was replaced with CRP-depleted autologous plasma (total volume = 8,085 mL). This intensive TPE-treatment was well tolerated, without adverse effects, or complications. The CRP plasma levels were: initial = 4.2 mg/L 6 h after acute myocardial infarction (AMI), pre-apheresis = 16.4 mg/L, and post-apheresis = 4.59 mg/L (CRP-depletion = 72%). There were neither significant changes observed in biochemistry nor any alterations in plasma hemostatic activity investigated before and after CRP-adsorption performed. <b><i>Conclusion:</i></b> Early performed CRP-apheresis is a promising innovative therapeutic approach for STEMI treatment that could provide a reduced size of infarction zone – with inferior occurrence of heart failure after AMI. However, precise and complete evaluation of the efficacy and safety of this treatment requires further multicenter randomized and larger clinical studies.
