Introduction: Results of currently available trials have shown divergent outcomes in diabetic patients undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Current guidelines do not recommend PCI in patients with diabetes and a SYNTAX score ≥ 23. Aim: To compare all-cause 4-year mortality after revascularization for complex coronary artery disease (CAD) in diabetics. Material and methods: The study group comprised consecutive patients with three-vessel CAD and/or unprotected left main CAD (≥ 50% diameter stenosis) without major hemodynamic instability, who were treated in two institutions with PCI or referred for CABG. Results: Out of 342 diabetics, 177 patients underwent PCI and 165 patients were referred for CABG. The incidence of all-cause death was different between diabetics treated with PCI or CABG at 4 years (16/177, 9.0% vs. 26/165, 15.8%, respectively, p = 0.03). The difference was not evident in non-diabetics (PCI: 41/450, 9.1% vs. CABG: 19/249, 7.6%, p = 0.173). In diabetics, there was a higher incidence of all-cause mortality in PCI patients with intermediate-high (≥ 23) SYNTAX scores compared with those with low (0–22) SYNTAX scores (10/56, 17.9% vs. 6/121, 5.0%, respectively, p < 0.01). On the other hand, diabetics who underwent CABG showed similar mortality rates irrespective of the SYNTAX scores (SYNTAX 0–22: 3/29, 10.3%; SYNTAX ≥ 23: 23/136, 11.9%, p = 0.46). In the subgroup analysis, there was no interaction according to presence or absence of left main CAD (p for interaction = 0.12) as well as according to diabetes status (p for interaction = 0.38), whereas gender and SYNTAX scores were differentiators between PCI and CABG with a p for interaction < 0.1. Conclusions: Our analysis supports recent evidence that diabetes is not a differentiator between PCI and CABG. © 2020 Termedia Publishing House Ltd.. All rights reserved.

Background/objectives The SYNTAX Score II (SSII) was proposed as a novel approach for objective individualized decision-making for optimal myocardial revascularization i.e. percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery. We sought to investigate how many lives may be saved by SSII use. Methods A total number of 651 consecutive SSII-naive-patients with complex coronary artery disease who were treated with PCI (n = 409) or referred to other institutions for CABG (n = 242) were included. All-cause mortality was ascertained in 96% of patients. The SSII was calculated for each patient. Results Based on the SSII treatment recommendation, CABG would have been the treatment of choice in 257/651 (39.5%) patients, PCI in 7/651 (1.1%) patients and CABG or PCI in 387/651 (59.4%) patients. Out of 257 patients in whom the treatment recommendation by SSII was CABG, 113/257 (44.0%) patients had actually CABG, while the remaining 144/257 (56.0%) underwent PCI. It was shown that 144/257 patients with treatment recommendations in favour of CABG who were treated with PCI had significantly higher mortality at 4 years when compared with patients with SSII treatment recommendation for PCI or equally favouring CABG and PCI (12.5% vs. 0.0% vs. 6.9%, respectively, P = 0.04). Conclusion The intuitive decision-making for choosing the optimal myocardial revascularization method differed predominantly from the SSII recommendation for CABG. The discordance between the SSII recommended revascularization strategy and the clinical decision was associated with a higher 4-year mortality i.e. one life may be saved if SSII would be calculated and followed consequently in 18 patients. © 2016 Elsevier Ireland Ltd

Factors associated with provoked PE may influence a biomarker's predictive value for the primary outcome. The aim of this study was to investigate the value of BNP, cTnI, CRP and D-Dimer measurements taken soon after hospital admission for the prediction of 30-day PE-caused death in patients with spontaneous versus provoked PE.Data were extracted from a pool of 726 consecutive PE patients enrolled in the multicenter Serbian PE registry. Blood concentrations of BNP, cTnI, CRP and D-dimer were measured during the first 24 h of hospitalization. BNP blood level had strong predictive value for the primary outcome in spontaneous PE (c-statistics 0.943, 95% CI 0.882–1.000, p = .001) and a slightly lower predictive outcome in provoked PE (c-statistics 0.824, 95% CI 0.745–0.902, p < .001). NRI and IDI showed that none of the markers, when added to BNP, could improve Cox regression prediction models for 30-day PE-related mortality in either the spontaneous or provoked PE group. Blood levels of BNP measured during the first 24 h of hospital admission had an excellent predictive value for 30-day PE-related mortality in spontaneous PE and slightly lower predictive value in provoked PE, whereas CRP, cTnI and D-Dimer did not contribute significantly to the predictive value of BNP in either group. © 2019 Elsevier B.V.

BACKGROUND: Left atrial (LA) strain analysis has emerged as a noninvasive technique for assessing LA function and early detection of myocardial deformation. Recently, its application has also shown promise in the pediatric population, spanning diverse cardiac conditions that demand accurate and sensitive diagnostic measures. OBJECTIVE: This research article endeavors to explore the role of LA strain parameters and contribute to the growing body of knowledge in pediatric cardiology, paving the way for more effective and tailored approaches to patient care. METHODS: A comprehensive literature review was conducted to gather evidence from studies using echocardiographic strain imaging techniques across pediatric populations. RESULTS: LA strain parameters exhibited greater sensitivity than conventional atrial function indicators, with early detection of diastolic dysfunction and LA remodeling in pediatric cardiomyopathy, children with multisystem inflammatory syndrome, rheumatic heart disease, as well as childhood renal insufficiency and obesity offering prognostic relevance as potential markers in these pediatric subpopulations. However, there remains a paucity of evidence concerning pediatric mitral valve pathology, justifying further exploration. CONCLUSION: LA strain analysis carries crucial clinical and prognostic implications in pediatric cardiac conditions, with reliable accuracy and sensitivity to early functional changes. © 2024 - IOS Press.

Background: Newly or already diagnosed cancer might significantly influence the clinical presentation, outcome, and therapy of acute pulmonary embolism (PE). Methods: Out of 1745 patients with acute PE, 66 patients were diagnosed with cancer during an initial hospitalization due to acute PE (where PE was the first clinical manifestation of cancer), 165 patients had known cancer treated in the last 6 months, and 1514 patients had acute PE without known or suspected cancer. The primary end-point of the present study was all-cause hospital death. The secondary end-points were the proportion of patients treated with thrombolysis and who had severe disease, and the ocurrence of major or clinically relevant nonmajor bleeding. Results: Patients with PE as the first presentation of cancer had the highest hospital mortality rate compared to the other two groups (HR for the mortality rate in patients without cancer as a reference, adjusted to four-stratum mortality risk, and Charlson's comorbidity index was 3.440; 95% confidence interval (CI), 1.795–6.591; p < 0.001). Patients with known cancer before PE had a significantly lower chance of being treated with thrombolysis than patients without cancer (OR, 0.523; 95% CI, 0.339–0.807; p = 0.003); additionally, this difference was attenuated but remained when the OR was adjusted to age (OR, 0.542; 95% CI, 0.351–0.838; p = 0.006). Patients with known cancer had a higher frequency of high-risk PE compared with patients without cancer (18.2% vs. 12.8%; p < 0.001). Patients with PE as the first manifestation of cancer had a higher frequency of intermediate-high-risk PE than those without (36.4% vs. 30.9%; p < 0.001). There was no significant difference in bleeding during hospitalization between groups. Conclusion: Patients with cancer had a more severe presentation of acute PE than patients without. Furthermore, patients with PE as the first manifestation of cancer had the highest hospital mortality rate, and patients with known cancer were least likely to be treated with thrombolysis. © 2025 The Author(s).

In patients with pulmonary embolism (PE), the D-dimer assay is commonly utilized as part of the diagnostic workup, but data on D-dimer for early risk stratification and short-term mortality prediction are limited. The purpose of this study was to determine D-dimer levels as a predictive biomarker of PE outcomes in younger (<50 years of age) compared to older patients. We conducted retrospective analysis for 930 patients diagnosed with PE between 2015 and 2019 as part of the Serbian University Multicenter Pulmonary Embolism Registry (SUPER).All patients had D-dimer levels measured within 24 hours of hospital admission. The primary outcome was mortality at 30 days or during hospitalization. Patients were categorized into two groups based on age (≤ 50 and >50 years of age). Younger patients constituted 20.5% of the study cohort. Regarding all-cause mortality, 5.2% (10/191)of patients died in group under the 50 years of age; the short-term all-causemortality was 12.4% (92/739) in older group.We have found that there was significant difference in plasma D-dimer level between patients ≤ 50 years of age and older group (>50), p= 0.006.D-dimer plasma level had good predictive value for the primary outcome in younger patients (c-statistics 0.710; 95% CI, 0.640-0.773; p<0.031). The optimal cutoff level for D-dimer to predict PE-cause death in patients aged > 50 years was found to be 8.8 mg/l FEU(c-statistics 0,580; 95% CI 0.544-0.616; p=0.049). In younger PE patients, D-dimer levels have good prognostic performance for 30-day all-cause mortalityand concentrations above 6.3 mg/l FEU are associated with increased risk of death. D-dimer in patients aged over 50 years does not have predictive ability for all-caused short-term mortality. The relationship between D-dimer and age in patients with PE may need further evaluation. © 2023 Ljiljana Jovanovic et al., published by Sciendo.

Background: Estimation of bleeding risk is an unmet need for individualized therapy in acute pulmonary embolism (PE) patients with increased mortality risk. Methods: We analyzed the association between various patients' characteristics and occurrence of major bleeding (MB) according to the modified International Society of Thrombosis and Hemostasis (ISTH) criteria (“overt” bleeding is the only modification from the original criteria) at 7 days from admission to the hospital and thrombolytic therapy with a tissue-plasminogen activator (tPA). Pulmonary embolism bleeding score index (PEBSI) was created using multivariate regression analyses, and finely, dichotomous index was used for the discrimination of patients with low risk for MB from those with high risk. Results: During the 6-year period (2015–2021) 367 PE patients were treated with tPA and included in the Regional PE registry. Among them, 29 (7.9%) fulfilled the criteria for MB. Five factors were identified as significantly associated with MB and were used to build the PEBSI score: previous bleeding, recent surgery, diabetes, the use of drugs that could be associated with bleeding, and anemia. PEBSI score showed c-index for 7-day MB 0.794 (95CI% 0.698–0.889). Patients with PEBSI scores of 0 or 1 had a low risk for MB (2.8%) and those with scores>1 had a high risk for MB (18.6%) (p < 0.001). Internal validation of PEBSI score using a randomly, equally split method confirmed the discriminative value of the PEBSI score. Conclusion: Novel PEBSI score has significant power to discriminate patients with low risk for MB on thrombolytic therapy from those with high risk. © 2022 Elsevier Ltd

Background: Acute pulmonary embolism (PE), due to hemodynamic disturbances, may lead to multi-organ damage, including acute renal dysfunction. The aim of our study was to investigate the predictive role of renal dysfunction at admission regarding the short-term mortality and bleeding risk in hospitalized PE patients. Methods: The retrospective cohort study included 1330 consecutive patients with PE. The glomerular filtration rate (GFR) was calculated using the serum creatinine value and Cocroft-Gault formula, at hospital admission. Primary outcomes were all-cause mortality and PE-related mortality in the 30 days following admission, as well as major bleeding events. Results: Based on the estimated GFR, patients were divided into three groups: the first with GFR < 30 mL/min, the second with GFR 30–60 mL/min, and the third group with GFR > 60 mL/min. A multivariable analysis showed that GFR at admission was strongly associated with all-cause death, as well as with death due to PE. Patients in the first and second group had a significantly higher risk of 30-day all-cause mortality (HR 7.109, 95% CI 4.243–11.911, p < 0.001; HR 2.554, 95% CI 1.598–4.081, p < 0.001). Fatal bleeding was recorded in 1.6%, 0.5% and 0.8% of patients in the first, second and in the third group (p < 0.05). There were no significant differences regarding major bleeding rates among the groups. Conclusion: Renal dysfunction at admission in patients with acute pulmonary embolism is strongly associated with overall PE mortality. © 2019 Elsevier B.V.

Background The incidence of the signs and symptoms of acute pulmonary embolism (PE) according to mortality risk, age and sex has been partly explored. Patients and methods A total of 1242 patients diagnosed with acute PE and included in the Regional Pulmonary Embolism Registry were enrolled in the study. Patients were classified as low risk, intermediate risk or high risk according to the European Society of Cardiology mortality risk model. The incidence of the signs and symptoms of acute PE at presentation with respect to sex, age, and PE severity was investigated. Results The incidence of haemoptysis was higher in younger men with intermediate-risk (11.7% vs 7.5% vs 5.9% vs 2.3%; p=0.01) and high-risk PE (13.8% vs 2.5% vs 0.0% vs 3.1%; p=0.031) than in older men and women. The frequency of symptomatic deep vein thrombosis was not significantly different between subgroups. Older women with low-risk PE presented with chest pain less commonly (35.8% vs 55.8% vs 48.8% vs 51.9%, respectively; p=0.023) than men and younger women. However, younger women had a higher incidence of chest pain in the lower-risk PE group than in the intermediate-risk and high-risk PE subgroups (51.9%, 31.4% and 27.8%, respectively; p=0.001). The incidence of dyspnoea (except in older men), syncope and tachycardia increased with the risk of PE in all subgroups (p<0.01). In the low-risk PE group, syncope was present more often in older men and women than in younger patients (15.5% vs 11.3% vs 4.5% vs 4.5%; p=0.009). The incidence of pneumonia was higher in younger men with low-risk PE (31.8% vs<16% in the other subgroups, p<0.001). Conclusion Haemoptysis and pneumonia are prominent features of acute PE in younger men, whereas older patients more frequently have syncope with low-risk PE. Dyspnoea, syncope and tachycardia are symptoms of high-risk PE irrespective of sex and age. © Author(s) (or their employer(s)) 2023. Re-use permitted under CC BY-NC. No commercial re-use.
