BackgroundST-elevation myocardial infarction (STEMI) occurs as a result of rupture of an atherosclerotic plaque in the coronary arteries. Limited data exist regarding the impact of culprit coronary vessel on hard clinical event rates. This study investigated the impact of culprit vessel on outcomes after primary percutaneous coronary intervention (PCI) of STEMI.MethodsA total of 29 832 previously cardiac healthy patients who underwent primary PCI between 2003 and 2014 were prospectively included from the Swedish Coronary Angiography and Angioplasty Registry and the Registry of Information and Knowledge about Swedish Heart Intensive care Admissions. Patients were stratified into three groups based on culprit vessel (right coronary artery (RCA), left anterior descending artery (LAD) and left circumflex artery (LCx)). The primary outcome was 1-year mortality. The secondary outcomes included 30-day and 5-year mortality, as well as heart failure, stroke, bleeding and myocardial reinfarction at 30 days, 1 year and 5 years. Univariable and multivariable analyses were done using Cox regression models.ResultsOne-year analyses revealed that LAD infarctions had the highest increased risk of death, heart failure and stroke compared with RCA infarctions, which had the lowest risk. Sensitivity analyses revealed that reduced left ventricular ejection fraction on discharge partially explained this increased relative risk in mortality. Furthermore, landmark analyses revealed that culprit vessel had no significant influence on 1-year mortality if a patient survived 30 days after myocardial infarction. Subgroup analyses revealed female sex and multivessel disease (MVD) as significant high-risk groups with respect to 1-year mortality.ConclusionsLAD and LCx infarctions had a relatively higher adjusted mortality rate compared with RCA infarctions, with LAD infarctions in particular being associated with an increased risk of heart failure, stroke and death. Culprit vessel had limited influence on mortality after 1 month. High-risk patient groups include LAD infarctions in women or with concomitant MVD.

Background: The AHA/ACC 2018 Cholesterol Guideline categorizes ASCVD patients into very high-risk vs. high-risk to guide intensive therapy. This categorization is based on clinical conditions, including reduced kidney function, but does not take into account albuminuria, the other kidney measure often available in clinical practice. Methods: We studied 838 participants with major ASCVD (myocardial infarction, ischemic stroke, or symptomatic peripheral artery disease) from the ARIC study at baseline (1996 - 98). We compared urine albumin-to-creatinine ratio (ACR) and the eight high-risk conditions of age 65+, reduced kidney function, diabetes, etc. in the AHA/ACC Guideline regarding their associations with composite outcome of all-cause mortality, myocardial infarction, ischemic stroke, and heart failure. We also evaluated risk classification by adding ACR to the eight high-risk conditions. Results: During a median follow-up of 8 years, 724 (86%) participants developed a composite outcome. ACR ≥30 mg/g was associated with the composite outcome (adjusted hazard ratio [aHR] 1.45 [95% CI 1.20, 1.75]) beyond the eight high-risk conditions (aHR of these conditions ranged from 0.96 to 2.46). The addition of ACR improved the c-statistic by 0.011 (95% CI 0.003-0.019) from 0.661 to 0.672. ACR classified 4.6% of high-risk group to very high-risk and 11.2% of very high-risk group to extremely very high-risk with a reasonable calibration (Figure). Even ACR ≥10 mg/g showed a significant aHR of 1.38 (1.17, 1.63) and classified 13.4% of high-risk and 18.1% very high-risk to a higher risk category. Of our patients with ASCVD, 77% had diabetes, hypertension, or low kidney function, clinical conditions in which the ACR assessment is recommended. Conclusions: In ASCVD, albuminuria was a strong predictor of major adverse cardiovascular outcome and improved risk prediction. Clinicians should pay attention to albuminuria, in addition to eGFR, when managing ASCVD patients.

Abstract Aims Patients with history of myocardial infarction (MI) undergoing percutaneous coronary intervention (PCI) remain at risk of recurrent ischaemic events. The optimal antithrombotic strategy for this cohort remains debated. Methods and results In this prespecified analysis of the TWILIGHT trial, we evaluated the impact of prior MI on treatment effect of ticagrelor monotherapy vs. ticagrelor plus aspirin in patients undergoing PCI with at least one clinical and one angiographic high-risk feature and free from adverse events at 3 months after the index PCI. The primary endpoint was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5, the key secondary endpoint was the composite of all-cause death, MI, or stroke, both at 12 months after randomization. 1937 (29.7%) patients with and 4595 (70.3%) without prior MI were randomized to ticagrelor and placebo or ticagrelor and aspirin. Patients with prior MI had increased rates of death, MI or stroke (5.7 vs. 3.2%, P < 0.001) but similar BARC 2–5 bleeding (5.0 vs. 5.5%, P = 0.677). Ticagrelor monotherapy reduced the risk of BARC 2–5 bleeding in patients with [3.4% vs. 6.7%; hazard ratio (HR): 0.50; 95% confidence interval (CI): 0.33–0.76] and without prior MI [4.2% vs. 7.0%; HR: 0.58; 95% CI: 0.45–0.76; pinteraction = 0.54). Rates of the key secondary ischaemic outcome were similar between treatment groups irrespective of history of MI (prior MI: 6.0% vs. 5.5%; HR: 1.09; 95% CI: 0.75–1.58; no prior MI: 3.1% vs. 3.3%; HR: 0.92; 95% CI: 0.67–1.28; pinteraction = 0.52). Conclusions Ticagrelor monotherapy is associated with significantly lower risk of bleeding events as compared to ticagrelor plus aspirin without any compromise in ischaemic prevention among high-risk patients with history of MI undergoing PCI.

Abstract Background Frailty is a clinical syndrome of increased vulnerability, resulting from age-associated decline in physiological reserve, compromising the ability to cope with acute stressors. Despite an increasing number of older, frail patients presenting with ST-elevation myocardial infarction (STEMI), there remains a paucity of guidance on how to approach the management of this complex group. Purpose To evaluate the impact of frailty on the management strategy and outcomes in older patients presenting with ST-elevation myocardial infarction. Methods A retrospective cohort study was performed, using linked patient records in The Nationwide Readmission Database. All patients aged ≥75 years that presented with STEMI (2015 – 2018) were included. International Classification of Disease (10th Edition; ICD-10) codes were used to ascertain exposures and outcomes. Frailty was quantified using the Hospital Frailty Risk Score (HFRS): an ICD-10-based scoring system that has been validated against established clinical frailty indices. Outcomes included: (i) management strategy (coronary angiography ± percutaneous coronary intervention, vs. conservative management), length of stay and 30-day mortality. Outcomes were modelled using multivariable binary logistic regression. Continuous variables are presented as: mean (standard deviation). Odds ratios (OR) are given with corresponding 95% confidence intervals (CI). Results From an overall dataset of 57,133,894 admissions, 368,201 patients presenting with STEMI were identified, of which 92,067 were aged ≥75 years. The mean age was 82.4 (5.1) years; 45,768 (49.7%) were female. The mean frailty score was 5.9 (SD 4.9, range 0 - 37.7). Patients were categorised by frailty status: low (HFRS <5; n=46,336 [50.3%]), intermediate (HFRS 5 - 15; n=40,493 [44.0%]) and high risk (HFRS >15; n=5,238 [5.7%]). Characteristics of the cohort are presented in Figure 1. Frail patients were less likely to undergo invasive management: 1,873 (35.5%) of the high risk group underwent coronary angiography vs. 36,888 (79.6%) of the low risk group; OR 0.14 (95% CI 0.13 - 0.15), P<0.001. Length of stay in hospital increased proportionately with frailty: a 2-unit increase in HRFS was associated with one additional day in hospital (p<0.001). 30-day mortality increased non-linearly with increasing HFRS and was markedly higher among patients at high risk for frailty, compared with those at low risk; OR 3.70 (95% CI 3.47 - 3.94; p<0.001). The relationship between frailty score and outcomes is presented in Figure 2. Frailty remained the greatest single predictor of outcome following adjustment for other covariates, including age. Conclusions Frail patients presenting with STEMI are less likely to undergo invasive management and more likely to experience adverse outcomes. Quantification of frailty offers an opportunity to identify and address modifiable risk factors to improve post-STEMI outcomes in this vulnerable group.

Background: This study evaluates the impact of peak preoperative troponin level on outcomes of coronary artery bypass grafting (CABG) for non-ST-elevation myocardial infarction (NSTEMI). Methods: This was a retrospective review of patients undergoing isolated CABG from 2011-2018 with presentation of NSTEMI. Patients were stratified into low- and high-risk groups based on median preoperative peak troponin (1.95ng/dL). Major cardiac and cerebrovascular events (MACCE) and mortality were compared. Multivariable analysis was performed to model risk factors for MACCE and mortality. Results: This study included 1,211 patients, 607 low- (≤1.95ng/dL) and 604 high-risk (>1.95ng/dL). Patients were well-matched with respect to age and comorbidity. High-risk patients had lower median preoperative ejection fraction (46.5% [IQR 35.0%-55.0%] vs 53.0% [IQR 40.0%-58.0%]) and higher incidence of preoperative intra-aortic balloon pump (15.9% vs 8.73%). Intensive care unit (47 hours [IQR 26-82] vs 43 hours [IQR 25-69]) and hospital lengths of stay (10 days [IQR 8-13] vs 9 days [IQR 8-12]) were longer in the high-risk group (each P<0.05). Postoperative complications and thirty-day, one- and five-year rates of both MACCE and survival were similar between groups. Peak troponin >1.95ng/dL was not associated with increased hazards for MACCE, mortality, or readmission in multivariable modeling. In sub-analyses, neither increasing troponin as a continuous variable nor peak troponin >10.00ng/mL were associated with increased hazards for these outcomes. Conclusions: Higher preoperative troponin levels are associated with longer lengths of stay but not MACCE or mortality following CABG. Dictating timing of CABG for NSTEMI based on peak troponin does not appear to be warranted.

Background: In the present study the perioperative complication rate is compared between high- and low-risk patients when carotid endarterectomy (CEA) is routinely performed under local anaesthesia (LA). Patients and methods: From January 2000 through June 2008 1220 consecutive patients underwent CEA under LA. High-risk patients fulfilled at least one of the following characteristics: ASA 4 classification, “hostile neck”, recurrent ICA stenosis, contralateral ICA occlusion, age ≥ 80 years. The combined complication rate comprised any new neurological deficit (TIA or stroke), myocardial infarction or death within 30 days after CEA, which was compared between patient groups. Results: Overall 309 patients (25%) were attributed to the high-risk group, which differed significantly regarding sex distribution (more males: 70% vs. 63%, p = 0,011), neurological presentation (more asymptomatic: 72% vs. 62%, p = 0,001) and shunt necessity (33% vs. 14%, p < 0,001). In 32 patients 17 TIAs and 15 strokes were observed. In 3 patients a myocardial infarction occurred. Death occurred in one patient following a stroke and in another patient following myocardial infarction, leading to a combined complication rate of 2,9% (35/1220). In the multivariate analysis only previous neurological symptomatology (OR 2,85, 95% CI 1,38-5,91) and intraoperative shunting (OR 5,57, 95% CI 2,69-11,55) were identified as independent risk factors for an increased combined complication rate. Conclusions: With the routine use of LA, CEA was not associated with worse outcome in high-risk patients. Considering the data reported in the literature, it does not appear justified to refer high-risk patients principally to carotid angioplasty and stenting (CAS) when LA can be chosen to perform CEA.

Az akut coronariaintervenció korában a myocardialis infarctust elszenvedő beteg nagyon gyorsan, néhány nap után haza vagy rehabilitációra kerül. A betegeknek a halálozása ugyanakkor az infarktust követő első hónapban a legmagasabb. Az elsősorban veszélyeztetettek a jelentős szívizomvesztést elszenvedő, csökkent szisztolés bal kamrai funkciójú betegek. Fontos lehet ezért ezen betegeknél – a telemedicina fejlődésével lehetőséget teremtő – új módszerek kidolgozása a ritmuszavarok otthoni monitorozására. Célkitűzés: Annak vizsgálata, hogy internetalapú folyamatos otthoni aritmiamonitorozás milyen biztonságossággal alkalmazható akut myocardialis infarctust elszenvedő, coronariaintervención átesett, csökkent balkamra-funkciójú betegeknél a hazabocsátás utáni első hónapban. Módszer: Számos transztelefonos EKG-monitor-rendszer működik, de a szerzők egy olyan új technológiával szerzett tapasztalataikat ismertetik, ahol a beteg aktivációjától független, folyamatos EKG-észlelés zajlik interneten keresztül. Az internettel nem rendelkező betegeknél kifejlesztésre került egy mobil internetre csatlakozó vevőegység is. Eredmények: Tíz, infarktus után otthonába távozó, 40% alatti ejekciós frakcióval rendelkező betegnél végeztünk monitorozást. A mérések kumulatív ideje összesen 170 nap volt. A teljesen zajmentes időszak 98% volt, hibamentes EKG 99% volt. Hatvanhat összes alarm átlagos nyugtázási ideje 27 szekundum volt. Az alarm/nap 0,39-nak adódott, és a riasztások pozitív prediktivitása 0,106 volt. Az összes alarmidő 29,8 percnek adódott, ami napi bontásban 10,5 szekundumot jelentett. Következtetések: Módszerünk alkalmasnak látszik a kórházból hazakerült betegek otthoni monitorozására úgy, hogy viszonylag nagy százalékban lehet hibamentes EKG-t regisztrálni a kifejlesztett mellpánt segítségével. Az alacsony riasztási idő azt jelenti, hogy sok beteg egyszerre történő monitorozása is kellő biztonsággal megoldható. A fenti módszert és eredményeinket azért tartjuk fontosnak bemutatni, mert ilyen „szoros” otthoni monitorozásról sem publikációt, sem terméket, illetve szolgáltatást nem találtunk.
