Aim. To compare the shortand medium-term outcomes of hemiarch and nonhemiarch replacement for ascending aortic aneurysm (AAA).Material and methods. The study included 151 patients with non-syndromic AAA who underwent an elective replacement. Patients were divided into two groups: group 1 (non-hemiarch, n=40) — standard ascending aortic replacement; group 2 (hemiarch, n=111) — ascending aortic replacement with the hemiarch anastomosis in conditions of moderate hypothermia and circulatory arrest with unilateral antegrade cerebral perfusion. To eliminate systematic differences between the compared groups, the propensity score matching (PSM) method was used.Results. Before PSM, there were no significant intergroup differences in the incidence of neurological complications, myocardial infarction, prolonged ventilation, or acute kidney injury. Bleeding-related reoperation rates and hospital mortality significantly differed between groups. After pseudo-randomization between the non-hemiarch and hemiarch groups, there were no significant differences in the incidence of neurological events, myocardial infarction, prolonged ventilation, reoperations for bleeding, acute renal injury, and hospital mortality. Median-term survival and freedom from aortic reoperations also did not show significant intergroup differences.Conclusion. Hemiarch replacement for AAA does not lead to an increase in the incidence of postoperative complications, as well as the risk of shortand mediumterm mortality compared with non-hemiarch.

Aortic Aneurysm Repair

Abstract Background There is no consensus nor recommendation for the surgical management of a minimally dilated adjacent aortic segment, such as the proximal aortic arch, at the time of proximal aortic aneurysm repair. Consequently, clinical equipoise exists regarding whether to extend the proximal aortic aneurysm repair to include the proximal aortic arch, by performing a hemiarch replacement, to mitigate the future risk of aortic aneurysm-related events in the proximal aortic arch. We hypothesized that additional hemiarch replacement to excise a non- or minimally aneurysmal proximal aortic arch does not have clinical benefit in patients undergoing proximal aortic aneurysm repair. Purpose To compare the long-term survival and freedom from aortic-arch reoperation in patients undergoing proximal aortic aneurysm repair with and without additional hemiarch replacement. Methods A retrospective review was performed of all patients undergoing proximal aortic aneurysm repair at our Aortic Center between 2005 and 2019. Inclusion criteria included all patients with a diagnosed root or ascending aortic aneurysm undergoing root or ascending aortic replacement with or without hemiarch replacement. Exclusion criteria were Age <18 years, presence of aortic arch diameter ≥4.5 cm, type A aortic dissection, previous ascending aortic replacement, aneurysm rupture, and endocarditis. A total of 1132 patients (hemiarch =307) met inclusion criteria. Propensity score matching in a 2:1 ratio (573 non-hemiarch: 288 hemiarch) on 19 baseline characteristics was performed. The median follow-up was 29.7 months (range: 0.1–153.8 months). Results Hemiarch patients had a significantly lower 10-year survival rate (86.7%; 95% CI, 79.2–94.8 in non-hemiarch vs 81.9%; 95% CI, 75.9–88.3 in hemiarch; P=0.005). There was no significant difference in 10- year cumulative incidence of aortic-arch reintervention (0.7%; 95% CI, 0.3–1.9 in non-hemiarch vs 0.69%; 95% CI, 0.17–2.75 in hemiarch; P=0.99). Hemiarch patients had higher rates of in-hospital mortality (1% in non-hemiarch vs 4% in hemiarch; P<0.001), stroke (3% in non-hemiarch vs 6% in hemiarch; P=0.047), reoperation for bleeding (4% in non-hemiarch vs 9% in hemiarch; P=0.011), and respiratory failure (7% in non-hemiarch vs 13% in hemiarch; P=0.006). In multivariable COX analysis, hemiarch replacement was significantly associated with long-term mortality (HR, 2.19; 95% CI, 1.36–3.55; P<.001) but not with aortic-arch reintervention (HR, 1.14; 95% CI, 0.63–2.10, P=0.66). Conclusions Proximal aortic aneurysm repair with additional hemiarch was associated with higher mortality without a decrease in aortic-arch reintervention rates compared to isolated proximal aortic aneurysm repair. Furthermore, aortic arch reintervention rate was extremely low. These data call for caution in adding hemiarch replacement at the time of proximal aortic aneurysm repair.

Abstract Background Several studies have found a so-called weekend effect that patients admitted at the weekends had worse clinical outcomes than patients admitted at the weekdays. We performed this retrospective cohort study to explore the weekend effect in four major cardiovascular emergencies in Taiwan. Methods The Taiwan National Health Insurance (NHI) claims database between 2005 and 2015 was used. We extracted 3811 incident cases of ruptured aortic aneurysm, 184,769 incident cases of acute myocardial infarction, 492,127 incident cases of ischemic stroke, and 15,033 incident cases of pulmonary embolism from 9,529,049 patients having at least one record of hospitalization in the NHI claims database within 2006 ~ 2014. Patients were classified as weekends or weekdays admission groups. Dates of in-hospital mortality and one-year mortality were obtained from the Taiwan National Death Registry. Results We found no difference in in-hospital mortality between weekend group and weekday group in patients with ruptured aortic aneurysm (45.4% vs 45.3%, adjusted odds ratio [OR] 1.01, 95% confidence interval [CI] 0.87–1.17, p = 0.93), patients with acute myocardial infarction (15.8% vs 16.2%, adjusted OR 0.98, 95% CI 0.95–1.00, p = 0.10), patients with ischemic stroke (4.1% vs 4.2%, adjusted OR 0.99, 95% CI 0.96–1.03, p = 0.71), and patients with pulmonary embolism (14.6% vs 14.6%, adjusted OR 1.02, 95% CI 0.92–1.15, p = 0.66). The results remained for 1 year in all the four major cardiovascular emergencies. Conclusions We found no difference in either short-term or long-term mortality between patients admitted on weekends and patients admitted on weekdays in four major cardiovascular emergencies in Taiwan.

Abstract Background To analyze incidence, use of therapeutic procedures, and in-hospital outcomes in patients with ST elevation myocardial infarction (STEMI) and non-ST elevation myocardial infarction (NSTEMI) according to the presence of type 2 diabetes (T2DM) in Spain (2016–2018) and to investigate sex differences. Methods Using the Spanish National Hospital Discharge Database, we estimated the incidence of myocardial infarctions (MI) in men and women with and without T2DM aged ≥ 40 years. We analyzed comorbidity, procedures, and outcomes. We matched each man and woman with T2DM with a non-T2DM man and woman of identical age, MI code, and year of hospitalization. Propensity score matching was used to compare men and women with T2DM. Results MI was coded in 109,759 men and 44,589 women (30.47% with T2DM). The adjusted incidence of STEMI (IRR 2.32; 95% CI 2.28–2.36) and NSTEMI (IRR 2.91; 95% CI 2.88–2.94) was higher in T2DM than non-T2DM patients, with higher IRRs for NSTEMI in both sexes. The incidence of STEMI and NSTEMI was higher in men with T2DM than in women with T2DM. After matching, percutaneous coronary intervention (PCI) was less frequent among T2DM men than non-T2DM men who had STEMI and NSTEMI. Women with T2DM and STEMI less frequently had a code for PCI that matched that of non-T2DM women. In-hospital mortality (IHM) was higher among T2DM women with STEMI and NSTEMI than in matched non-T2DM women. In men, IHM was higher only for NSTEMI. Propensity score matching showed higher use of PCI and coronary artery bypass graft and lower IHM among men with T2DM than women with T2DM for both STEMI and NSTEMI. Conclusions T2DM is associated with a higher incidence of STEMI and NSTEMI in both sexes. Men with T2DM had higher incidence rates of STEMI and NSTEMI than women with T2DM. Having T2DM increased the risk of IHM after STEMI and NSTEMI among women and among men only for NSTEMI. PCI appears to be less frequently used in T2DM patients After STEMI and NSTEMI, women with T2DM less frequently undergo revascularization procedures and have a higher mortality risk than T2DM men.

Introduction: The GenTAC Registry ( G enetically Triggered T horacic A ortic Aneurysms and Cardiovascular C onditions) followed patients with aortopathies over 8 years among 8 centers with the goal of evaluating cardiovascular outcomes. Methods: Enrollment initiated in 2007, and data were collected until 2015. We included diagnoses with >100 participants: Bicuspid aortic valve with aneurysm (BAV, n=879), Marfan syndrome (MFS, n=861), Familial thoracic aortic aneurysm or dissection (FTAAD, n=378), Other thoracic aortic aneurysm at < 50 years of age (Other<50, n=524), Turner syndrome (TS, n=298), Vascular Ehlers Danlos syndrome (VEDS, n=149), and Loeys-Dietz syndrome (LDS, n=121). We identified patients who underwent elective ascending aortic replacement, total unique dissections, and time to first dissection. With MFS as a reference population and adjusted for sex, endpoints were analyzed by a Firth penalized Cox-PH regression model to account for diagnosis groups with low event numbers. Results: LDS participants at a mean age of (24.5 ± 15.0y) were youngest at elective aortic surgery followed by MFS (32.3 ±12.3y), TS (37.6 ±13.6y), VEDS (35.0 ±SD 7.4y), Other<50 (40.3 ±SD 10.3y), FTAAD (42.9 ±14.2y), and BAV(49.4 ± 13.8 y). Dissections were reported in all diagnosis groups with a total of 472 unique dissections in 3210 patients (14%). Mean age at first dissection was in the third decade for LDS, TS, MFS, VEDS and in the fourth decade for BAV, FTAD, and Other<50. Adjusted hazard ratio for time to first dissection was higher in LDS, 1.77 (95%CI 1.14- 2.77), compared to MFS and other diagnosis groups (Figure 1). Conclusions: Reported aortic dissections were prominent in the GenTAC cohort. Despite elective surgery at a younger age, LDS patients had a higher hazard risk of dissection compared to other diagnosis groups.

Összefoglaló. Bevezetés: A szívinfarktust megelőző revascularisatiós beavatkozások prognosztikai jelentőségével kapcsolatban kevés elemzés ismeretes, hazai adatokat eddig nem közöltek. Célkitűzés: A szerzők a Nemzeti Szívinfarktus Regiszter adatait felhasználva elemezték a koszorúér-revascularisatiós szívműtétet (CABG) túlélt betegek prognózisát heveny szívinfarktusban. Módszer: Az adatbázisban 2014. 01. 01. és 2017. 12. 31. között 55 599 beteg klinikai és kezelési adatait rögzítették: 23 437 betegnél (42,2%) ST-elevációval járó infarktus (STEMI), 32 162 betegnél (57,8%) ST-elevációval nem járó infarktus (NSTEMI) miatt került sor a kórházi kezelésre. Vizsgáltuk a CABG után fellépő infarktus miatt kezelt betegek klinikai adatait és prognózisát, amelyeket azon betegek adataival hasonlítottunk össze, akiknél nem szerepelt szívműtét a kórelőzményben (kontrollcsoport). Eredmények: A betegek többsége mindkét infarktustípusban férfi volt (62%, illetve 59%). Az indexinfarktust megelőzően a betegek 5,33%-ánál (n = 2965) történt CABG, amely az NSTEMI-betegeknél volt gyakoribb (n = 2357; 7,3%). A CABG-csoportba tartozó betegek idősebbek voltak, esetükben több társbetegséget (magas vérnyomás, diabetes mellitus, perifériás érbetegség) rögzítettek. Az indexinfarktus esetén a katéteres koszorúér-intervenció a kontrollcsoport STEMI-betegeiben gyakoribb volt a CABG-csoporthoz viszonyítva (84% vs. 71%). Az utánkövetés 12 hónapja során a betegek 4,7–12,2%-ában újabb infarktus, 13,7–17,3%-ában újabb katéteres koszorúér-intervenció történt. Az utánkövetés alatt a CABG-csoportban magasabbnak találtuk a halálozást. A halálozást befolyásoló tényezők hatásának korrigálására Cox-féle regressziós analízist, illetve ’propensity score matching’ módszert alkalmaztunk. Mindkét módszerrel történt elemzés azt mutatta, hogy a kórelőzményben szereplő koszorúér-revascularisatiós műtét nem befolyásolta a túlélést. Amennyiben a beteg kórelőzményében szerepelt a koszorúérműtét, az indexinfarktus nagyobb eséllyel volt NSTEMI, mint STEMI (HR: 1,612; CI 1,464–1,774; p<0,001). Következtetés: A kórelőzményben szereplő koszorúér-revascularisatiós műtét nem befolyásolta a szívinfarktus miatt kezelt betegek életkilátásait. Orv Hetil. 2021; 162(5): 177–184. Summary. Introduction: Little analysis is known about the prognostic significance of revascularization interventions before myocardial infarction; no domestic data have been reported so far. Method: The authors use data from the Hungarian Myocardial Infarction Registry to analyze the prognosis of patients with acute myocardial infarction who had previous coronary artery bypass grafting (CABG). Between 01. 01. 2014. and 31. 12. 2017, 55 599 patients were recorded in the Registry: 23 437 patients (42.2%) had ST-elevation infarction (STEMI) and 31 162 patients (57.8%) had non-ST-elevation infarction (NSTEMI). The clinical data and prognosis of patients treated for infarction after CABG were compared with those of patients without a CABG history. Results: The majority of patients were male (59% and 60%, respectively). Prior to index infarction, CABG occurred in 5.33% of patients (n = 2965), which was more common in NSTEMI (n = 2357; 7.3%). The CABG patients were older and had more comorbidities (hypertension, diabetes mellitus, peripheral vascular disease). For index infarction, percutaneous coronary intervention was more common in STEMI patients in the control group compared to CABG (84% vs. 71%). At 12 months of follow-up, 4.7–12.2% of patients had reinfarction, and 13.7–17.3% had another percutaneous coronary intervention. During the full follow-up, the CABG group had higher mortality. Cox regression analysis and propensity score matching were used to correct for the effect of other factors influencing mortality. Both analyses showed CABG did not affect survival. In the CABG group, the index infarction was more likely to be NSTEMI than STEMI (HR: 1.612; CI 1.464–1.774; p<0.001). Conclusion: The history of CABG does not affect the life expectancy of patients treated for an acute myocardial infarction. Orv Hetil. 2021; 162(5): 177–184.

Abstract Background Acute myocardial infarction (AMI) in the very elderly is associated with high morbidity and mortality. Because the majority of study population in clinical researches focusing on the very elderly with AMI were octogenarians, clinical evidences regarding AMI in nonagenarians are sparse. The aim of the present study was to compare in-hospital clinical outcomes of AMI between octogenarians and nonagenarians. Methods We included consecutive 415 very elderly (≥80 years) patients with AMI, and divided into the nonagenarian group (n=38) and the octogenarian group (n=377). Clinical characteristics and in-hospital outcomes were compared between the 2 groups. Furthermore, we used propensity-score matching to find the matched octogenarian group (n=38). Results Percutaneous coronary interventions (PCI) to the culprit of AMI were similarly performed between the nonagenarian (86.8%) and octogenarian (87.0%) groups The incidence of in-hospital death in the nonagenarian group (13.2%) was similar to that in the octogenarian group (14.6%) (P=0.811). The length of hospital stay was significantly shorter in the nonagenarian group (7.4±4.2 days) than that in the octogenarian group (15.4±19.4 days) (P<0.001). After using the propensity-score matching, the incidence of in-hospital death was less in the nonagenarian group (13.2%) than in the matched octogenarian group (21.1%) without reaching statistical significance (P=0.361). The length of hospitalization was significantly shorter in the nonagenarian group (7.4±4.2 days) than in the matched octogenarian group (17.8±37.0 days) (P=0.01). Clinical outcomes Nonagenarian group (n=38) Octogenarian group (n=377) P value In-hospital death, n (%) 5 (13.2) 55 (14.6) 0.811 Length of hospital stay (days) 7.4±4.2 15.4±19.4 <0.001 Length of CCU stay (days) 3.3±2.5 4.7±5.1 0.109 LVEF (%) 48.2±9.2 50.8±13.7 0.152 Peak CPK (U/L) 1424.8±1580.8 1640.1±2394.4 0.912 CCU indicates Coronary care unit; LVEF, Left ventricular ejection fraction; CPK, Creatine kinase. Flow-chart Conclusions The in-hospital mortality of nonagenarians with AMI was comparable to that of octogenarians with AMI. In-hospital outcomes in nonagenarians with AMI may be acceptable as long as acute medical management including PCI to the culprit of AMI is performed. Acknowledgement/Funding None

Aim: To compare hospital mortality in patients with aspiration-associated pneumonia treated with ceftriaxone (CTRX) and in those treated with ampicillin/sulbactam (ABPC/SBT). Methods: From a Japanese multicentre observational study cohort of patients with pneumonia, those diagnosed with pneumonia and having at least one aspiration-related risk factor were selected. Propensity score-matching analysis was used to balance baseline characteristics of the participants and compare hospital mortality of patients treated with CTRX and those treated with ABPC/SBT. Results: Hospital mortality did not significantly differ between patients treated with CTRX and those treated with ABPC/SBT (6.6 vs 10.7%, risk difference -4.0, 95% CI [-9.4, 1.3]; p = 0.143). Conclusion: Further studies are needed to compare CTRX and ABPC/SBT treatments in patients with aspiration-associated pneumonia.

Introduction: Sepsis is a systemic inflammatory response syndrome caused by infectious diseases, with cytokines possibly having an important role in the disease mechanism. Acrylonitrile-co-methallyl sulfonate surface-treated (AN69ST) membrane is expected to improve the outcomes of patients with sepsis through cytokine adsorption. Objective: This study aimed to investigate the clinical effect of the AN69ST membrane in comparison to standard continuous renal replacement therapy (CRRT) membranes for panperitonitis due to lower gastrointestinal perforation. Methods: Using the Diagnosis Procedure Combination database, we identified adult patients with sepsis due to panperitonitis receiving any CRRT. Propensity score matching was used to compare patients who received CRRT with the AN69ST membrane (AN69ST group) and those who received CRRT with other membranes (non-AN69ST group). The primary outcome measure was in-hospital mortality. Results: A total of 528 and 1,445 patients were included in the AN69ST group and in the non-AN69ST group, respectively. Propensity score matching resulted in 521 pairs. There was no significant difference in in-hospital mortality (32.1 vs. 35.5%; p = 0.265) and 30-day mortality (41.3 vs. 42.8%, p = 0.074) between the AN69ST group and the non-AN69ST group. Conclusion: There is no significant difference in-hospital mortality between CRRT with the AN69ST membrane and CRRT with standard CRRT membranes for panperitonitis due to lower gastrointestinal perforation. These results indicate that the AN69ST membrane is not superior to the standard CRRT membrane.
