RESUMO
BACKGROUND: Surgical aortic valve replacement (SAVR) is among the most commonly performed valvular surgeries. Despite many previous studies conducted in this setting, the impact of sex on outcomes in patients undergoing SAVR is still unclear. AIMS: This study aimed to define sex differences in short- and long-term mortality in patients undergoing SAVR. METHODS: We analyzed retrospectively all the patients undergoing isolated SAVR from January 2006 to March 2020 in the Department of Cardiovascular Surgery and Transplantology in John Paul II Hospital in Kraków. The primary endpoint was in-hospital and long-term mortality. Secondary endpoints included the duration of hospital stay and perioperative complications. Groups of men and women were compared with regard to the prosthesis type. Propensity score matching was performed to adjust for differences in baseline characteristics. RESULTS: A total number of 4 510 patients undergoing isolated surgical SAVR were analyzed. A follow- up median (interquartile range [IQR]) was 2120 (1000-3452) days. Females made up 41.55% of the cohort and were older, displayed more non-cardiac comorbidities, and faced a higher operative risk. In both sexes, bioprostheses were more often applied (55.5% vs. 44.5%; P <0.0001). In univariable analysis, sex was not linked to in-hospital mortality (3.7% vs. 3%; P = 0.15) and late mortality rates (23.37% vs. 23.52 %; P = 0.9). Upon adjustment for baseline characteristics (propensity score matching analysis) and considering 5-year survival, a long-term prognosis turned out to be better in women (86.8%) compared to men (82.7%, P = 0.03). CONCLUSIONS: A key finding from this study suggests that female sex was not associated with higher in-hospital and late mortality rates compared to men. Further studies are needed to confirm longterm benefits in women undergoing SAVR.

INTRODUCTION: Peripheral venous blood sample may be used to obtain acid base balance parameters (PVABP) measured in rapid pointofcare test (POCT) analyzers on admission to an emergency department (ED). Thus, lactates, anion gap (AG), and base excess (BE) may be early prognostic markers in patients with myocardial infarction (MI). OBJECTIVES: We aimed to confirm the relationship between PVABP on admission and the outcome in patients with MI treated with percutaneous coronary intervention (PCI). PATIENTS AND METHODS: This was a retrospective, observational analysis of MI patients admitted primarily to an ED and secondly transferred to PCI department. RESULTS: A total of 336 patients (41.1% STelevated MI, 58.9% non-STelevated MI) were divided according to their lactate level, that is, G1 group with lactate below or equal to 2.0 mmol/l (n = 207) and G2 group with lactate above >2.0 mmol/l (n = 129). G2 patients had higher values of AG (mean, [SD], 9.6 [4.3] vs 6.8 [3.2] mEq/l; P <0.001) and lower BE (median [interquartile range], -0.7 [-3.9 to 0.8] vs 1.0 [-0.2 to 2.4] mEq/l; P <0.001). Inhospital nonsurvivors had higher values of lactates (4.0 [2.0-8.7] vs 1.7 [1.3-2.4] mmol/l; P <0.001), AG (10.5 [4.6] vs 7.7 [3.8] mEq/l; P <0.001), and lower BE (-4.8 [-10.6 to -1.8] vs 1.5 [-0.8 to 2.3] mEq/l; P <0.001) than the survivors. Lactates, AG, and BE correlated with Global Registry of Acute Coronary Events score (r = 0.361, P <0.001; r = 0.158, P = 0.004; r = -0.383, P <0.001, respectively). Only BE independently predicted both 30- and 365day mortality in the whole group (hazard ratio [HR], 0.79; 95% CI, 0.65-0.95; P = 0.01 and HR, 0.89; 95% CI, 0.76-0.99; P = 0.04, respectively) as well as inhospital mortality among patients without infarctrelated outofhospital cardiac arrest (odds ratio, 0.74; 95% CI, 0.57-0.97; P = 0.03). CONCLUSIONS: In the patients admitted to the ED with MI treated with PCI the evaluation of PVABP in POCT analyzers may be a reliable tool for early risk stratification.

BACKGROUND: Mortality after coronary artery bypass grafting (CABG) is primarily thromboembolic by nature. We investigated whether impaired fibrinolysis observed in cardiovascular diseases is associated with long-term mortality following CABG. METHODS: The study population comprised 292 consecutive patients (aged 64.6 ± 8.1 years) who underwent scheduled CABG. We measured plasma clot lysis time (CLT) preoperatively as a measure of fibrinolysis capacity. Cardiovascular and all-cause deaths were recorded during a median follow-up of 13.8 years. RESULT: CLT positively correlated with age (r = .56, p < .001), fibrinogen (r = .25, p = .002) and EuroSCORE I (r = .32, p < .001). The cardiovascular and overall mortality rates were 3.0 and 4.9 per 100 patient-years (32.4% vs 52.8%) respectively. In patients who died from cardiovascular and all causes, CLT was prolonged compared with survivors (both p < .050). Multivariable Cox regression analysis adjusted for potential confounders showed that long-term cardiovascular and all-cause deaths were associated with CLT (HR per 10 min 1.206; 95% CI 1.037-1.402, p = .015 and HR 1.164; 96% CI 1.032-1.309, p = .012), low-density lipoprotein cholesterol (HR per 1 mmol/L 1.556; 95% CI 1.205-2.010, p < .001 and HR 1.388; 96% CI 1.125-1.703, p = .002), C-reactive protein (HR per 10 mg/L 1.171; 95% CI 1.046-1.312, p = .006 and HR 1.127; 95% CI 1.005-1.237, p = .022) and EuroSCORE I (HR 1.173; 95% CI 1.016-1.355, p = .030 and HR 1.183; 95% CI 1.059-1.317, p = .003 respectively). Type 2 diabetes was solely associated with overall mortality (HR 1.594; 96% CI 1.088-2.334, p = .017). CONCLUSIONS: In this study, we showed that reduced fibrin clot susceptibility to fibrinolysis is weekly associated with long-term mortality in advanced CAD.

There are many arguments for the safety and efficacy of COVID-19 vaccines in pregnancy. The aim of this study is to describe the level of vaccination acceptance, to find the factors that most influence the decision to vaccinate, and to describe the scale of changes in vaccination acceptance influenced by medical information on the safety, efficacy, and benefits of vaccination among pregnant women. A total of 300 patients completed the questionnaire, including 150 in Poland and 150 in the Ukraine. The level of vaccination acceptance was assessed before and after medical consultation. There were 53 (35.3%) patients with the intention to get vaccinated in Poland and 25 (16.7%) in the Ukraine. After consultation with a physician, this increased to 109 (72.6%) in Poland and 69 (46%) in the Ukraine. The main factors influencing the acceptance of vaccinations were the fear of harming the foetus (OR-0.119, CI-0.039-0.324 p < 0.001), complications in pregnancy (OR-0.073 CI-0.023-0.197 p < 0.001), and limitations in the vaccination programme (OR-0.026 CI-0.001-0.207 p < 0.001). Medical information about the safety, effectiveness and benefits of vaccinations among pregnant women, provided during a medical visit, may increase the acceptance of vaccinations by 105.6%, as among Polish patients, and by 176%, as among pregnant women from the Ukraine.
RESUMO
BACKGROUND AND AIMS: Large amounts of clot-bound lipoproteins were reported in proteomic analysis of plasma clot but their impact on fibrin clot properties is unknown. We investigated a contribution of lipid profile and apolipoproteins (apo) to the prothrombotic plasma fibrin clot phenotype in patients with aortic stenosis (AS). METHODS: In 138 patients with isolated severe AS, we determined serum apoA-I, A-II, B, C-II, C-III, E, oxidized low-density lipoprotein (OxLDL) and lipoprotein(a) concentrations. Plasma fibrin clot permeability (Ks), maximal absorbance (MaxAbsCLT2018 and MaxAbsLys50), and fibrinolytic capacity were studied using 3 plasma-based lysis assays (CLT2018, CLT, and Lys50), and compared with well-matched patients without AS (control group). RESULTS: After adjustment for confounding factors, including statin use, only low-density lipoprotein cholesterol (LDL-C) and apoB levels were inversely associated with Ks. Triglycerides, apoC-II, and C-III were associated with MaxAbsCLT2018 and MaxAbsLys50, explaining 56-64% of their variability. CLT2018 and CLT showed associations with total cholesterol, LDL-C, triglycerides, and OxLDL as well as with apoB, C-II, C-III, and E. ApoA-I, C-II, and C-III but not serum lipids were associated with Lys50. Only CLT2018 was associated with lipoprotein(a). ApoC-III, B, A-I, and E along with estimated glomerular filtration rate and OxLDL predicted hypofibrinolysis in multiple regression analysis. AS patients had higher lipoprotein(a) (+34.9%) and apoA-I (+25.9%) levels and less compact fibrin clots (-13.3% lower MaxAbsCLT2018, -53.2% lower MaxAbsLys50, and +28.3% higher Ks) displaying higher susceptibility to lysis (-17.9% lower Lys50) in comparison with control group. CONCLUSIONS: Apolipoproteins and OxLDL contribute to prothrombotic fibrin clot phenotype in severe AS. Moreover, apolipoproteins better than serum lipids predicted hypofibrinolysis, which provides additional argument for a role of elevated lipoproteins in the prothrombotic state.

BACKGROUND: Post-pulmonary embolism (PE) syndrome occurs in up to 50% of PE patients. The pathophysiology of this syndrome is obscure. OBJECTIVE: We investigated whether enhanced oxidative stress and prothrombotic state may be involved in post-PE syndrome. METHODS: We studied 101 normotensive noncancer PE patients (aged 56.5 ± 13.9 years) on admission, after 5-7 days and after a 3-month anticoagulation, mostly with rivaroxaban. A marker of oxidative stress, 8-isoprostane, endogenous thrombin potential, fibrinolysis proteins, clot lysis time (CLT) and fibrin clot permeability (Ks ), along with PE biomarkers, were determined. RESULTS: Patients who developed the post-PE syndrome (n = 31, 30.7%) had at baseline 77.6% higher N-terminal brain natriuretic propeptide and 46.8% higher growth differentiation factor 15, along with 14.1% longer CLT associated with 34.4% higher plasminogen activator inhibitor-1 as compared to subjects without post-PE syndrome (all P < .05). After 5-7 days, only hypofibrinolysis was noted in post-PE syndrome patients. When measured at 3 months, prolonged CLT and reduced Ks were observed in post-PE syndrome patients, accompanied by 23.8% higher growth differentiation factor 15 and 35.8% higher plasminogen activator inhibitor-1 (all P < .05). 8-isoprostane levels ≥108 pg/ml (odds ratio=4.36; 95% confidence interval 1.63-12.27) and growth differentiation factor 15 ≥ 1529 pg/ml (odds ratio=3.89; 95% confidence interval 1.29-12.16) measured at 3 months were associated with higher risk of developing post-PE syndrome. CONCLUSIONS: Enhanced oxidative stress and prothrombotic fibrin clot properties could be involved in the pathogenesis of the post-PE syndrome. Elevated growth differentiation factor 15 assessed at 3 months might be a new biomarker of this syndrome.

BACKGROUND: Adequate thromboprophylaxis reduces the risk of venous thromboembolism (VTE) by half in hospitalized patients. A single scoring system is recommended to improve thromboprophylaxis. OBJECTIVES: We investigated the impact of implementing a computerized system to prevent VTE in inpatients with pulmonary diseases and identified predictors of the overuse and underuse of pharmacological thromboprophylaxis. MATERIAL AND METHODS: We compared the use of thromboprophylaxis with enoxaparin in all patients hospitalized for pulmonary disorders in a tertiary hospital in Kraków, Poland, in 2014 and 2017, before and after introducing a computerized thromboprophylaxis system. Using the Caprini risk assessment, the overuse and underuse of thromboprophylaxis were defined as the use in patients with <5 points and ≥5 points, respectively. RESULTS: Both cohorts (n = 2007 in 2014 and n = 1570 in 2017) were similar with regard to age and sex. The most frequent causes of hospitalization were intestinal lung disease (39.0%) and lung cancer (20.4%) in 2017, and pneumonia (38.8%) and lung cancer (27.5%) in 2014. Although the use of thromboprophylaxis was comparable in both cohorts, it was used more frequently in high VTE risk patients in 2017 compared with 2014 (96.98% compared to 29.17%, respectively, p < 0.001), with a concomitant reduction in its overuse (2.26% compared to 6.26%, respectively, p < 0.001). In 2017, no predictors of thromboprophylaxis underuse were identified. The overuse was mainly predicted by the diagnosis of airway diseases (odds ratio (OR) = 0.16, 95% confidence interval (95% CI) = 0.02-1.17, p = 0.015). CONCLUSIONS: Our findings indicate the benefits of using a computerized system to manage pharmacological thromboprophylaxis in pulmonary inpatients.

INTRODUCTION AND OBJECTIVES: There is a paucity of data comparing the left radial approach (LRA) and right radial approach (RRA) for percutaneous coronary intervention (PCI) in all-comers populations and performed by operators with different experience levels. Thus, we sought to compare the safety and clinical outcomes of the RRA and LRA during PCI in "real-world" patients with either stable angina or acute coronary syndrome (ACS). METHODS: To overcome the possible impact of the nonrandomized design, a propensity score was calculated to compare the 2 radial approaches. The study group comprised 18 716 matched pairs with stable angina and 46 241 with ACS treated with PCI and stent implantation between 2014 and 2017 in 151 tertiary invasive cardiology centers in Poland (the ORPKI Polish National Registry). RESULTS: The rates of death and periprocedural complications were similar for the RRA and LRA in stable angina patients. A higher radiation dose was observed with PCI via the LRA in both clinical presentations (stable angina: 1067.0±947.1 mGy vs 1007.4±983.5 mGy, P=.001; ACS: 1212.7±1005.5 mGy vs 1053.5±1029.7 mGy, P=.001). More contrast was used in LRA procedures but only in ACS patients (174.2±75.4mL vs 167.2±72.1mL, P=.001). Furthermore, periprocedural complications such as coronary artery dissection (0.16% vs 0.09%, P=.008), no-reflow phenomenon (0.65% vs 0.49%, P=.005), and puncture site bleeding (0.09% vs 0.05%, P=.04) were more frequently observed with the LRA in ACS patients. There was no difference in mortality between the 2 groups (P=.90). CONCLUSIONS: Our finding of poorer outcomes with the LRA may be related to lower operator experience with this approach. While both the LRA and RRA are safe in the setting of stable angina, the LRA was associated with a higher rate of periprocedural complications during PCI in ACS patients.

Data on the clinical outcomes comparing synthetic fluorocarbon polymer polytetrafluoroethylene- (PTFE, GraftMaster) and polyurethane- (Papyrus) covered stents (CSs) to seal coronary artery perforations (CAPs) are limited. We aimed to evaluate 30-day and 1-year clinical outcomes after PCI complicated by CAP and treated with CS. We assessed 106 consecutive patients with successful CAP sealing (122 CSs): GraftMaster (51 patients, 57 CSs) or Papyrus CS (55 patients, 65 CSs). The primary endpoint was the occurrence of major adverse cardiac events (MACE), defined as the composite of cardiac death, target lesion revascularisation (TLR), and myocardial infarction (MI). The mean age of subjects was 69 ± 9.6 years (53.8% males). No significant differences were identified between the GraftMaster and Papyrus groups at the 30-day follow-up for MACE, cardiac death, MI and stent thrombosis (ST), while significantly lower rate of TLR and TVR (p = 0.02) were confirmed in the Papyrus group. At one year, differences remained similar between stents for MACE, a trend towards a lower rate of TLR (p = 0.07), MI (p = 0.08), and ST (p = 0.08), and higher for cardiac death (p = 0.07) was observed in the Papyrus group. This real-life registry of CAP illustrated that the use of Papyrus CS is associated with lower rates of TLR and TVR at 30-day follow-up in comparison to the GraftMaster CSs and no significant differences between both assessed CS at one year of follow-up.
RESUMO
BACKGROUND: Acute myocardial infarction (AMI) is an incredibly destructive disease when it occurs in a young patient. Thus, the investigation of the disease presentation and treatment options seem to be particularly important in young patients with AMI. AIMS: The study objective was to investigate the differences between young and older patients diag-nosed with AMI in terms of clinical characteristics and treatment strategies. METHODS: The patient data comes from the National Registry of Procedures of Invasive Cardiology (ORPKI). Between 2014 and 2017, data of more than 230 000 patients with a diagnosis of AMI were collected in that registry. Young patients were defined as under 40 years old. RESULTS: Young patients with AMI (n = 3208, 1.3%) compared with older patients with AMI were more often men (86.3% vs. 65.8%; P <0.001) with higher body weight (mean 85.9 vs. 79.7 kg; P <0.001). Typical risk factors of coronary heart disease were less frequent in younger patients than in older patients. However, in the under-40 group, there was a significantly higher number of current smokers (37.5% vs. 23.0%; P <0.001). Young patients with AMI were more often diagnosed with ST-segment elevation myocardial infarction (STEMI; 62.0% vs. 50.0%; P <0.001). Moreover, they had more frequently non-significant ste-nosis in coronary arteries diagnosed (14.4% vs. 6.8%; P <0.001). The left anterior descending artery was more frequently an infarct-related artery in young patients (51.3% vs. 36.3%; P <0.001). Bioresorbable vascular scaffolds were more commonly implanted in young patients with AMI than in the older ones (5.6% vs. 0.9%; P <0.001). The relative number of AMI in the young patients increased from 1.20% in 2014 to 1.43% in 2017. CONCLUSIONS: Smoking is the most common risk factor in young adults. The relative number of AMI in young patients is growing.

OBJECTIVES: Family history of stroke increases stroke risk, however mechanisms underlying this association remain unclear. We investigated whether family history of stroke is related to increased prevalence of stroke risk factors, unhealthy behaviors and self-reported stroke symptoms in middle-aged adults. MATERIALS AND METHODS: In a cross-sectional study conducted from November 2018 to January 2021 in 100 primary care facilities in Poland we evaluated adults aged 40-65 years (n = 2207, women 57.4%, median age 55 years) for stroke risk factors, healthy behaviors, family history of stroke, self-reported stroke symptoms and stroke knowledge using structured questionnaires. Patients were categorized based on family history of stroke defined as ≥1 first-degree relative with documented stroke. RESULTS: Family history of stroke was reported by 571 (25.9%) individuals who were older (median age 56 vs. 54 years, p = 0.00001) and after adjustment for age more frequently suffered from hypertension (61.5% vs. 53.7%, p = 0.024) and prior transient ischemic attack (2.1% vs. 0.9%, p = 0.019), but not other risk factors. However, they were less obese (34.5% vs. 39.1%, p = 0.03). Women, but not men, with family history of stroke (n = 339, 26.8%) had greater prevalence of atrial fibrillation (7.4% vs. 3.9%, p = 0.037). Family history of stroke was associated with higher prevalence of any self-reported stroke symptom (32.9% vs. 23.2%, p < 0.00001), but not with unhealthy dietary behaviors or low level of knowledge about stroke. CONCLUSIONS: Family history of stroke is associated with greater prevalence of certain risk factors and self-reported stroke symptoms, which indicates the need for closer surveillance of middle-aged individuals at risk.

BACKGROUND: The impact of acute total occlusion (TO) of the culprit artery in non-ST-segment elevation myocardial infarction (NSTEMI) is not fully established. We aimed to evaluate the clinical and angiographic phenotype and outcome of NSTEMI patients with TO (NSTEMITO) compared to NSTEMI patients without TO (NSTEMINTO) and those with ST-segment elevation and TO (STEMITO). METHODS: Demographic, clinical and procedure-related data of patients with acute myocardial infarction who underwent percutaneous coronary intervention (PCI) between 2014 and 2017 from the Polish National Registry were analysed. RESULTS: We evaluated 131,729 patients: NSTEMINTO (n = 65,206), NSTEMITO (n = 16,209) and STEMITO (n = 50,314). The NSTEMITO group had intermediate results compared to the NSTEMINTO and STEMITO groups regarding mean age (68.78 ± 11.39 vs 65.98 ± 11.61 vs 64.86 ± 12.04 (years), p < 0.0001), Killip class IV on admission (1.69 vs 2.48 vs 5.03 (%), p < 0.0001), cardiac arrest before admission (2.19 vs 3.09 vs 6.02 (%), p < 0.0001) and death during PCI (0.43 vs 0.97 vs 1.76 (%), p < 0.0001)-for NSTEMINTO, NSTEMITO and STEMITO, respectively. However, we noticed that the NSTEMITO group had the longest time from pain to first medical contact (median 4.0 vs 5.0 vs 2.0 (hours), p < 0.0001) and the lowest frequency of TIMI flow grade 3 after PCI (88.61 vs 83.36 vs 95.57 (%), p < 0.0001) and that the left circumflex artery (LCx) was most often the culprit lesion (14.09 vs 35.86 vs 25.42 (%), p < 0.0001). CONCLUSIONS: The NSTEMITO group clearly differed from the NSTEMINTO group. NSTEMITO appears to be an intermediate condition between NSTEMINTO and STEMITO, although NSTEMITO patients have the longest time delay to and the worst result of PCI, which can be explained by the location of the culprit lesion in the LCx.

INTRODUCTION: The beneficial outcome of the radial (RA) over femoral approach (FA) in ST-segment elevation myocardial infarction (STEMI) has been widely demonstrated. However, most of the studies excluded patients with STEMI and cardiogenic shock (CS). OBJECTIVES: We sought to evaluate periprocedural outcomes of percutaneous coronary intervention (PCI) with RA and FA in patients with STEMI complicated by CS using data from the Polish National PCI Registry (ORPKI). PATIENTS AND METHODS: A total of 3,565 consecutive patients with STEMI and CS treated with emergent PCI and stent implantation were included. Data was collected prospectively between 2014 and 2018 from 151 tertiary primary-PCI centers in Poland. To avoid possible selection bias, a propensity score matching (PSM) was used to create 945 matched pairs treated via RA or FA. RESULTS: No differences were reported in baseline characteristics, clinical presentation and delays in treatment between RA and FA after the PSM. Similar radiation doses and the total amount of contrast were used in both groups. A similar rate of periprocedural complications was observed in both RA and FA. However, RA was associated with reduced periprocedural mortality (9.4% (89) vs. 18.6% (176); P=0.001) and lower incidence of cardiac arrest (9.7% (92) vs. 16.1% (152); P=0.001). In multivariable analysis, FA was the strongest independent predictor for increased periprocedural mortality (OR 2.087, 95% CI 1.629-2.674; P=0.001). CONCLUSIONS: The radial approach was associated with lower periprocedural mortality compared with FA in patients with STEMI complicated by CS. RA seems to be a valuable option in technically feasible situations.

INTRODUCTION: Myxomatous mitral valve disease (MMVD) in dogs inevitably causes renal dysfunction. These interactions are known as the cardiorenal syndrome (CRS). The main aims of the study were to evaluate whether renal resistive index (RRI) may be useful as a non-invasive marker in subclinical stage of kidney injury in dogs with MMVD and to compare RRI with SDMA and Cyst C. METHODS: Forty-four dogs were divided into two groups: control-15 healthy dogs and the heart group-29 dogs with MMVD (ACVIM class Cc). Study protocol included: anamnesis, clinical examination, electrocardiography, echocardiography, chest radiography, abdominal ultrasonography with measurements of the renal resistive index (RRI), urine, and blood analysis. RESULTS: The RRI in the heart group was significantly higher 0.725 ± 0.035 versus control group 0.665 ± 0.028 (p < 0.00085). The RRI cut-off point in dogs with stable chronic heart failure (CHF) under 8 years is 0.775, in older 0.64. RRI was similar in MMVD dogs treated with ACE-I + furosemide and dogs treated ACE-I + torasemide + pimobendan + spironolactone. There was no correlation between RRI and SDMA or Cyst C. CONCLUSION: RRI is more sensitive than creatinine, SDMA and Cyst C to reveal kidney injury in MMVD dogs class Cc younger than 8 years.

OBJECTIVE: There are conflicting data on the clinical outcomes of percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) based on the time of admission to the catheterization laboratory. Thus, we aimed to assess clinical outcomes in an unselected cohort of consecutive patients with STEMI treated with PCI during on-and-off hours of work. METHODS: A total of 99,783 patients were included in the analysis. Patients were divided using the most frequently used definition: On-hours (Monday-Friday 07:00 AM-04:59 PM); off-hours (Monday-Friday 05:00 PM-06:59 AM, Saturday, Sunday, and nonworking holidays) (37,469 matched pairs). To avoid potential preselection bias, a propensity score was calculated to compare on-and-off hour groups. RESULTS: Higher radiation doses were observed for PCIs performed during off-hours (1055.2(±1006.5) vs. 1081.6(±1003.25)[mGy] and p = 0.001). A similar prevalence of periprocedural complications was observed during on- and off-hours. However, there was a higher mortality rate during off-hours than during regular working hours (1.17% (439) vs. 1.49% (559) and p = 0.001). CONCLUSIONS: Primary PCIs in STEMI performed during off-hours might be associated with a higher rate of periprocedural mortality and higher radiation doses than procedures conducted during regular working hours.

BACKGROUND: Prothrombotic fibrin clot properties are associated with higher early mortality risk in acute pulmonary embolism (PE) patients. It is unknown whether different types of PE are associated with particular clot characteristics. METHODS: We assessed 126 normotensive, noncancer acute PE patients (median age: 59 [48-70] years; 52.4% males), who were categorized into central versus peripheral PE with or without concomitant deep vein thrombosis (DVT). Plasma fibrin clot permeability (K s), clot lysis time (CLT), thrombin generation, platelet-derived markers, and fibrinolytic parameters were measured on admission. Plasma fibrin clot morphology was assessed by scanning electron microscopy (SEM). RESULTS: Patients with central PE (n = 76; 60.3%) compared with peripheral PE (n = 50; 39.7%) had 17.8% higher K s and 14.3% shortened CLT (both p < 0.01 after adjustment for potential confounders including fibrinogen), with no differences between segmental and subsegmental PE. SEM analysis demonstrated larger fibrin fiber diameter and pore size in central PE compared with peripheral PE (both p < 0.01). For isolated PE, there was 23.3% higher K s in central PE than in peripheral PE (n = 24; 19%) with no differences in other variables. Central PE combined with DVT (n = 45; 35.7%), as compared with central isolated PE (n = 31; 24.6%), was associated with shortened CLT (all p < 0.05). CONCLUSION: Our findings suggest that looser fibrin networks composed of thicker fibers with increased susceptibility to lysis characterize patients with central PE, suggesting that fibrin clot phenotype affects the size of thrombi occluding the pulmonary arteries, highlighting the role of fibrin structures in thrombus formation and stability.

INTRODUCTION: Several methods for measuring fibrinolytic capacity in plasma have been developed yielding frequently inconsistent results. We investigated which factors determine fibrinolytic capacity in three plasma-based assays. MATERIAL AND METHODS: In 80 apparently healthy controls (aged 43 ± 10 years, 50 women [62.5%]) we evaluated fibrinolysis using three assays: (1) by Pieters et al. (CLT2018), (2) by Lisman et al. (CLT), and (3) by Carter et al. (Lys50). Coagulation factors and fibrinolytic proteins, including histidine-rich glycoprotein (HRG) and γ'-fibrinogen, were determined. Regression models were performed to identify determinants of lysis times. RESULTS: Positive correlations were observed between CLT2018 and both CLT (r = 0.73) and Lys50 (r = 0.61), as well as between CLT and Lys50 (r = 0.46, all p < 0.001). The main determinants of both CLT2018 and CLT were plasminogen activator inhibitor-1 (PAI-1), followed by thrombin-activatable fibrinolysis inhibitor (TAFI) and α2-antiplasmin. Histidine-rich glycoprotein was a predictor of the longest-normal CLT2018 alone (OR 1.04, 95% CI 1.02-1.06). α2-Antiplasmin and fibrinogen levels, followed by PAI-1 and TAFI determined Lys50. After adjustment for age, sex, and body mass index, C-reactive protein (CRP) was an independent predictor of the top quartiles of the three lysis times. CONCLUSIONS: We showed that apart from PAI-1, TAFI, and α2-antiplasmin, several other factors, in particular CRP, can affect the results of global fibrinolysis tests used in research. Our findings may help understand why the choice of a specific fibrinolysis assay can affect the presence and/or magnitude of intergroup differences in fibrinolytic capacity in a given disease state.

Denser fibrin networks which are relatively resistant to lysis can predispose to post-thrombotic syndrome (PTS). Histidine-rich glycoprotein (HRG), a blood protein displaying antifibrinolytic properties, is present in fibrin clots. We investigated whether HRG may affect the risk of PTS in relation to alterations to fibrin characteristics. In venous thromboembolism (VTE) patients, we evaluated plasma HRG levels, plasma clot permeability, maximum absorbance, clot lysis time and maximum rate of increase in D-dimer levels released from clots after 3 months of the index event. We excluded patients with cancer and severe comorbidities. After 2 years of follow-up, 48 patients who developed PTS had 18.6% higher HRG at baseline. Baseline HRG positively correlated with clot lysis time, maximum absorbance, and thrombin-activatable fibrinolysis inhibitor (TAFI) activity but was inversely correlated with plasma clot permeability and maximum rate of increase in D-dimer levels released from clots. On multivariate regression model adjusted for age, fibrinogen and glucose, independent predictors of PTS were recurrent VTE, baseline HRG level, and TAFI activity. VTE recurred in 45 patients, including 30 patients with PTS, and this event showed no association with elevated HRG. Our findings suggest that increased HRG levels might contribute to the development of PTS, in part through prothrombotic fibrin clot properties.

INTRODUCTION: It has been suggested that the time of admission during the day and night may influence the clinical outcomes of patients with acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI). OBJECTIVES: The aim of this study was to assess the impact of day- and nighttime admissions on the clinical outcomes of patients with AMI undergoing PCI. PATIENTS AND METHODS: This retrospective cohort study was based on the data on PCIs performed in Poland from January 2014 to December 2017, prospectively collected in the National Registry of Invasive Cardiology Procedures (ORPKI). Day hours were defined as the time interval between 7:00 am and 10:59 pm. The study endpoints included the allcause inhospital mortality rate and major adverse cardiovascular and cerebrovascular events (MACCEs) at 30day,12month, and 36month followup. RESULTS: A total of 2919 patients were included in the study (2462 [84.3%] treated during the day hours). STsegment elevation myocardial infarction (1993 [68.3%]) was the main indication for PCI. We demonstrated that the 30day mortality rate was significantly higher in patients treated during the night hours than during the day hours (P = 0.01). Night hours were also among the independent predictors of increased 30day mortality (hazard ratio, 1.54; 95% CI, 1.11-2.16; P = 0.01). No significant differences were observed in inhospital, 12month, and 36month mortality rates between patients treated during the night and day hours. There were no significant differences in the MACCE rates at the followup timepoints. CONCLUSIONS: Primary PCI for AMI is associated with increased 30day mortality among patients treated during the night hours compared with those managed during the day hours.
