This study aimed to assess the prognostic significance of total leukocyte count (TLC) and hemoglobin (Hb) levels upon admission for patients with acute pulmonary embolism (PE), considering the European Society of Cardiology (ESC) model for mortality risk. 1622 patients from a regional PE registry were included. Decision tree statistics were employed to evaluate the prognostic value of TLC and Hb, both independently and in conjunction with the ESC model. The results indicated all-cause and PE-related in-hospital mortality rates of 10.7% and 6.5%, respectively. Subgrouping patients based on TLC cut-off values (≤11.2, 11.2–16.84, >16.84 × 109/L) revealed increasing all-cause mortality risks (7.0%, 11.8%, 30.2%). Incorporating Hb levels (≤126 g/L or above) further stratified the lowest risk group into two strata with all-cause mortality rates of 10.1% and 4.7%. Similar trends were observed for PE-related mortality. Notably, TLC improved risk assessment for intermediate–high-risk patients within the ESC model, while Hb levels enhanced mortality risk stratification for lower-risk PE patients in the ESC model for all-cause mortality. In conclusion, TLC and Hb levels upon admission can refine the ESC model’s mortality risk classification for patients with acute PE, providing valuable insights for improved patient management. © 2023 by the authors.

Introduction: Psychological characteristics of patients, depression, stress and anxiety are recognized as important confounding risk factors for ischemic heart disease. However, the impact of psychological characteristics on coronary ischemia and vice versa remain poorly understood. Aim: To demonstrate the interplay of psychological characteristics, depression, stress and anxiety with coronary ischemia estimated with fractional flow reserve (FFR). Material and methods: From 2014 to 2016, 147 patients who were planned for FFR measurement were included in this study. Psychological characteristics of patients were evaluated using the Depression, Anxiety and Stress Scale 21 items (DASS 21) self-report questionnaire. Results: Comparing the FFR ischemic vs. FFR non-ischemic groups, a significant difference was observed regarding results achieved for the depression, anxiety and stress scales. Multivariate logistic regression analysis was used to model the correlation between FFR and the DAS scale. It was clear, when controlling for previous myocardial infarction, that FFR was significant in all analyses. However, when the Canadian Cardiovascular Society grading of angina pectoris (CCS) class was entered in the model, FFR was not a significant predictor of anxiety, but was significant in other analysis. Conclusions: Higher degrees of the psychological characteristics depression, stress and anxiety were observed in the group of patients with coronary ischemia, corresponding to lower fractional flow values.

Objective Little is known about parameters that lead to improvement in QoL in individual patients. We analysed the data of the Cardiac Insufficiency Bisoprolol Study in Elderly (CIBIS-ELD) in order to answer the question of how and to what extent change in health-related QoL during up-titration with bisoprolol vs. carvedilol is influenced by clinical and psychosocial factors in elderly patients with heart failure. Methods This is a QoL analysis of CIBIS-ELD, an investigator-initiated multi-center randomised phase III trial in elderly patients (65 years or older) with moderate to severe heart failure. Clinical parameters such as New York Heart Association functional class, heart rate, left ventricular ejection fraction (LVEF), 6-min walk distance, as well as the physical and psychosocial component scores on the short-form QoL health survey (SF36) and depression were recorded at baseline and at the final study visit. Results Full baseline and follow-up QoL data were available for 589 patients (292 in the bisoprolol and 297 in the carvedilol group). Mean physical and psychosocial QoL improved significantly during treatment. In regression analyses, changes in both SF36 component scores from baseline to follow-up were mainly predicted by baseline QoL and depression as well as change in depression over time. Changes in cardiac severity markers were significantly weaker predictors. Conclusion Mean QoL increased during up-titration of bisoprolol and carvedilol. Both baseline depression and improvement in depression over time are associated with greater improvement in QoL more strongly than changes in cardiac severity measures. © 2013 European Federation of Internal Medicine.

The aim of this study was to investigate the impact of nondipping arterial blood pressure pattern and the metabolic syndrome (MS), as well as their interaction, on left ventricular (LV) structural and function remodeling. The study included 352 never-treated hypertensive patients with and without MS. Nondipping pattern and MS, separately, as well as their interaction, significantly impacted LV structure, LV geometry pattern, systolic, diastolic and global function in hypertensive patients. Abdominal obesity was the only MS criterion which was simultaneously associated with LV hypertrophy, LV diastolic dysfunction and, LV global dysfunction. © Informa Healthcare USA, Inc.

Purpose: The aim of this study was to investigate the influence of metabolic syndrome (MS) on left ventricular (LV) structure and function depending on gender. Methods: The study included 235 never-treated MS subjects and 138 controls. MS was defined as the presence of three or more National Cholesterol Education Program's Adult Treatment Panel III criteria. All the subjects underwent laboratory blood tests and complete two-dimensional, pulsed, and tissue Doppler echocardiography. Results: LV structure, diastolic function, and global function were significantly impaired in all MS subjects. Multivariate analysis of individual MS factors showed that increased blood pressure (BP) and impaired fasting glucose were independently associated with LV hypertrophy in women, whereas the only independent predictor in men was increased BP. The same analysis revealed that the combination of impaired glucose level, abdominal obesity, and dyslipidemia was associated with LV hypertrophy only in women. Higher BP, impaired fasting glucose, and triglycerides level were independently associated with LV diastolic dysfunction in women, whereas higher BP was the only independent predictor in men. The combination of increased BP, fasting glucose, and dyslipidemia was independently associated with LV diastolic dysfunction only in women. Conclusions: Different MS factors are responsible for LV remodeling in women and men. The metabolic sequence of MS is more important for LV remodeling in women. © 2013 Wiley Periodicals, Inc.

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).

Aims: To examine the relationship between admission glucose (AG) level and short-term in-hospital mortality and to investigate the association between hyperglycemia and major bleeding in PE patients with and without DMT2. Methods: We evaluated 1165 patients with diagnosed acute PE with multi-detector computed tomography pulmonary angiography (MDCT-PA) enrolled in the Regional multicenter PE registry (REPER). The study population was classified to patients with diabetes mellitus type 2 (DMT2) and those without diabetes. According to quartiles of AG patients, both groups separately were categorized into four subgroups (DMT2 I: < 7.5 mmol/L; II: 7.5–10.0 mmol/L; III: 10.0–15.7 mmol/L; IV: > 15.7 mmol/L and (non-DMT2 I: < 5.5 mmol/L; II: 5.5–6.3 mmol/L; III: 6.3–7.9 mmol/L; IV: > 7.9 mmol/L). Results: All-cause mortality was higher in the DMT2 group (9.5% vs. 18.2%, p < 0.001), and PE-cause mortality was 6% for the patients without DMT2 and 12.4% for DMT2 patients (p = 0.02). The patients in the fourth AG quartiles in both groups, without DMT2 and with DMT2, had significantly higher all-cause and PE-cause in-hospital mortality compared with the first quartile. Rates of major bleeding were similar between the groups. On the multivariable analysis, after adjusting for age, gender and mortality risk, the adherence in the fourth AG quartile had an independent predictive value for all-cause death (HR 2.476, 95% CI 1.017–6.027) only in DM patients. Conclusion: In our cohort of patients with acute PE, diabetes was associated with increased rates for all-cause and PE-cause mortality. © 2021, Springer-Verlag Italia S.r.l., part of Springer Nature.

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 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.

Background: Diastolic dysfunction and lack of contractile reserve are unfavorable prognostic predictors in patients with dilated cardiomyopathy (DCM). Aims: This study aims to assess whether diastolic dysfunction and lack of dipyridamole-induced contractile reserve were additive predictors of poor outcome in patients with DCM. Methods: A total of 116 patients with DCM and ejection fraction (EF<35%) were studied by dipyridamole echo (0.84 mg/kg over 10 min). At rest, a restrictive filling pattern was defined as: E/A ratio >2 and an E-wave deceleration time of <140 ms on transmitral flow velocity profile. Results: Rest wall motion score index (WMSI) was 2.2±0.3 and decreased to 1.9±0.41 after dipyridamole (p<0.001). During follow-up (median 26.5 months), 22 cardiac deaths occurred. At multivariate analysis, dipyridamole-induced contractile reserve yielded significant incremental prognostic value (RR=0.275, p<0.006) over NYHA class (RR=1.971, p<0.03), angiotensin-converting enzyme inhibitor therapy (RR=0.173, p<0.001), and left ventricular end-diastolic diameter (RR=1.131, p<0.001). The worst prognostic combination was the presence of restrictive pattern at rest and the absence of contractile reserve (ΔWMSI<0.15). Conclusion: In patients with DCM, the ominous combination of restrictive transmitral flow pattern and lack of contractile reserve during dipyridamole stress predicts an unfavourable outcome. © 2004 European Society of Cardiology.

To assess the presence of subclinical left ventricular myocardial dysfunction in subjects with high-normal blood pressure (BP) and untreated arterial hypertension, using three-dimensional (3D) echocardiography strain analysis. This cross-sectional study included 49 subjects with optimal BP, 50 subjects with high-normal BP, and 50 newly diagnosed untreated hypertensive patients matched by gender and age. All the subjects underwent 24 h blood pressure monitoring and complete two-dimensional and 3D echocardiography examination. The enrolled subjects were grouped according to 24 h systolic BP values, dividing the subjects with optimal BP from those with high-normal BP and the hypertensive patients (cut-off values were 120 and 130 mmHg, respectively). 3D global longitudinal strain was significantly lower in the high-normal BP group and the hypertensive patients, in comparison with the optimal BP group (-20.5 ± 3.3 vs. -18.7 ± 2.8 vs. -17.6 ± 2.7 %, p < 0.001). Similar results were obtained for 3D global circumferential strain (-18.6 ± 3 vs. -17.1 ± 2.9 vs. -16 ± 2.5 %, p < 0.001), as well for 3D global radial strain (49.4 ± 9.5 vs. 44.7 ± 8.1 vs. 43.5 ± 7.8 %, p = 0.002), and global area strain (-31.2 ± 4.8 vs. -28.7 ± 4.2 vs. -27.1 ± 4.5 %, p < 0.001). LV twist was increased in the hypertensive patients in comparison with the high-normal and the optimal BP groups (10.1° ± 2.4° vs. 10.8° ± 2.6° vs. 13.8° ± 3.1°, p < 0.01), whereas untwisting rate significantly and gradually decreased from the optimal BP group, across the high-normal BP group, to the hypertensive patients (-135 ± 35 vs. -118 ± 31 vs. -102 ± 27°/s, p < 0.001). 3D echocardiography revealed that the subjects with high-normal BP suffered subclinical impairment of LV mechanics similar as the hypertensive patients. © 2014 Springer Science+Business Media.

OBJECTIVES: The objective of this study was to investigate whether there are differences between brain natriuretic peptide (BNP) levels and computed tomography pulmonary angiography (CTPA) parameters, in patients with acute PE, with respect of sex. BACKGROUND: Acute pulmonary embolism (PE) may provoke sudden right ventricle overload and stretching of their thin walls, causing significant raise of BNP blood levels, which correlates to acute PE severity. The properties of RV are different between sexes. METHODS: This retrospective analysis was gained from the data of 1612 PE patients from the regional PE register. The patients have had CTPA verification of PE, with described localization of thrombus masses, as well as the ratio between RV and left ventricle (RV/LV), and BNP as biomarker, measured during the first 24 hours upon admission. RESULTS: Out of 96 male patients with detected central thrombus, 75.0% patients had an increase in BNP level compared to 25.0% patients with normal BNP value (p<0.001). Of the 94 female patients with central thrombus, 85.1% patients had an elevated BNP level, compared to 14.9% patients, with BNP normal values (p<0.001). Of the 135 male patients with RV/LV>1, 79.3% of them, had elevated BNP, compared to 20.7% patients whose BNP level was normal (p<0.001). Out of 123 female patients with RV/LV>1, 91.1% patients had elevated BNP compared to 8.9%, whose BNP was normal (p<0.001). CONCLUSION: Elevated BNP blood level correlates with CTPA parameters, such as the presence of central thrombus and the ratio between right and left ventricles greater than 1, in patients with acute PE, regardless of sex (Tab. 2, Fig. 2, Ref. 23).
