RESUMO
BACKGROUND: Infective endocarditis (IE) is a severe valvular disease associated with high morbidity and mortality. AIMS: This preliminary study aimed to evaluate patient profiles and treatment outcomes of IE in Poland and compare them with European IE characteristics. METHODS: We conducted a prospective multicenter observational cohort study - the POL-ENDO registry - in IE patients from 134 hospitals in Poland recruited between August 2022 and August 2023. We evaluated demographic, clinical, imaging, and treatment outcome data. A comparison of the Polish patients with those assessed in the EURO-ENDO registry between January 2016 and March 2018 was performed. RESULTS: Of a total of 880 IE patients, 622 were male (70.7%). The POL-ENDO participants were older (61.4 [16.7] years vs. 59.25 [18.03] years; P = 0.001). Native-valve IE occurred more often in Poland (82.3% vs. 56.6%; P <0.001). Transthoracic echocardiography was performed more frequently in Poland (93.6% vs. 89.8%; P <0.001). New imaging techniques (computed tomography/magnetic resonance imaging/positron emission tomography/single-photon emission computed tomography) were less frequently used in Poland (computed tomography: 41.3% vs. 53.2%; P <0.001; magnetic resonance imaging: 6.4% vs. 18.7%; P <0.001). Heart failure occurred more often in Poland as an in-hospital complication (31.4% vs. 14.1%; P <0.001). Surgical treatment was less frequently performed in Poland (36.9% vs. 51.2%; P <0.001). In-hospital mortality was higher in Poland (21% vs. 17%; P = 0.008). CONCLUSION: Polish IE patients were significantly older and had more comorbidities. New imaging techniques are less frequently used in Poland. Echocardiography was performed more frequently in Poland as the diagnostic mainstay. Surgical treatment was significantly less frequent in Poland. In-hospital mortality in Poland is higher.

Introduction: Radial artery is the preferred access for coronary interventions. However, the procedure is sometimes interrupted by a spasm which causes pain, prolongs the procedure, and can force the access crossover. Aim: To observe factors contributing to a symptomatic radial artery spasm. Material and methods: In this prospective study, we present results of 103 consecutive patients regarding radial artery spasm and angiographic image of the punctured artery. Angiography of the radial artery was performed in 70 (68.0%) patients. Potential risk factors for radial artery spasm were evaluated. Results: The overall incidence of the radial artery spasm was high - 25 (24.3%). Signs of spasm were present in 37.1% of radial artery angiographies before the procedure and 60.1% after, however, it did not always indicate a symptomatic spasm. Risk factors related to radial artery spasm included female sex (OR = 2.94, p = 0.02), failure of the first puncture attempt (OR = 3.12, p = 0.014) and use of non-hydrophilic sheath (OR = 9.56, p = 0.036). Radial artery narrowing at the tip of the sheath was also a risk factor for spasm (p = 0.022). No spasms were observed after hydrophilic sheath application (n = 13). The administration of a radial cocktail was not observed to significantly decrease the spasm odds. Conclusions: Risk factors for radial artery spasm include female sex and multiple puncture attempts. Hydrophilic sheath coating protects against radial artery spasm. Overall signs of a spasm in the angiography are common and do not imply a symptomatic spasm, which can be predicted by a tight narrowing at the tip of the sheath.
RESUMO
(1) Background: Coexistent coronary artery disease (CAD) might influence the ability of electrocardiogram (ECG) to identify echocardiographic left ventricular hypertrophy (ECHO-LVH) in patients with aortic stenosis (AS). We aimed to assess the relation between ECG-LVH (by the Sokolov-Lyon or Cornell criteria) and ECHO-LVH considering coexistent CAD. (2) Methods: We retrospectively analyzed the medical records of 74 patients (36 males) with severe AS who were hospitalized in the University Hospital in Cracow from 2021 to 2022. (3) Results: ECHO-LVH was present in 49 (66%) patients, whereas 35 (47.3%) patients had ECG-LVH. There was no difference between the rate of ECG-LVH in patients with vs. without ECHO-LVH. Single-vessel and multi-vessel CAD were diagnosed by invasive coronary angiography in 18% and 11% of patients, respectively. The sensitivity of the classical ECG-LVH criteria with regard to ECHO-LVH was low, reaching at best 41% for the Sokolov-Lyon and Cornell criteria. The results were similar and lacked a pattern when considering patients without significant stenosis, with single- and multi-vessel disease separately. Correlations between the left ventricular mass index and ECG-derived parameters were weak and present solely for the Lewis index (r = 0.31), R wave's amplitude >1.1 mV in aVL (r = 0.36), as well as the Cornell (r = 0.32) and Sokolov-Lyon (r = 0.31) voltage criteria (p < 0.01). The presence, location of stenoses, and CAD extent were not associated with the presence of either ECHO-LVH or ECG-LVH, irrespective of individual ECG-LVH criteria. (4) Conclusions: The sensitivity of classical ECG criteria for echocardiographic LVH in severe AS is low, regardless of coexistent CAD or its angiographic extent.
RESUMO
Background and Objectives: Biochemical and molecular regulation of both adaptive and pathological responses of heart tissue to ischemic injury is widely investigated. However, it is still not fully understood. Several biomarkers are tested as predictors of left ventricle (LV) remodeling after myocardial infarction (MI). The aim of this study was to assess the relationship between selected microRNAs (miRNAs) and LV function and morphology in patients after MI. Materials and Methods: Selected miRNAs related to heart failure were assessed in the acute phase of MI: miR-150-3p, miR-21-5p, miR-19b-3p, miR-155-5p, miR-22-5p. Echocardiography with 3D imaging was performed at baseline and after 6 months. Remodeling was defined as >20% increase in LV end-diastolic volume, whereas reverse remodeling was defined as >10% reduction in LV end-systolic volume. Results: Eighty patients entered the registry. Remodeling occurred in 26% and reverse remodeling was reported in 51% of patients. In the presented study, none of the analyzed miRNAs were found to be a significant LV remodeling predictor. The observed correlations between miRNAs and other circulating biomarkers of myocardial remodeling were relatively weak. Conclusions: Our analysis does not demonstrate an association between the analyzed miRNAs and LV remodeling in patients with MI.

Background and Objectives: Coronary angiography is the gold standard for diagnosing coronary artery disease (CAD). In the case of borderline changes, patients require further diagnosis through ischemia assessment via one of the recommended methods of invasive evaluation. This study aimed to assess whether clinical factors influence the risk of a positive result in invasive myocardial ischemia assessment and if these potential factors change with the patient's age and the consistency of ischemia assessment. Materials and Methods: Data were collected retrospectively on all consecutive patients hospitalized in the University Hospital in Krakow between 2020 and 2021, on whom physiological assessments of coronary circulation were performed. Patients were divided into two groups: patients aged 60 or younger and patients older than 60. Results: Despite the older patients having more risk factors for CAD, their physiological assessment results of borderline lesions were similar to those of the younger patients. Positive fractional flow reserve (FFR) assessments were obtained from almost 50% of vessels. In the younger patients, cigarette use and type 2 diabetes mellitus increased the risk of a positive FFR result by 3.5 and 2.5 times, respectively. In the older patients, male gender and peripheral vascular disease significantly increased the risk of a positive FFR by 2.5 and 2 times, respectively. Conclusions: Clinical characteristics of patients undergoing physiological assessment of borderline coronary stenosis varied significantly by age. Refining the definition of borderline lesions to include age, gender, and other factors may improve the identification of patients who would benefit from physiological assessment and coronary revascularization.

BACKGROUND AND AIMS: Primary percutaneous coronary intervention (PCI) is regarded as the most preferred strategy in ST-segment elevation myocardial infarction (STEMI). Thrombolysis in Myocardial Infarction (TIMI) flow grade has been an important and cohesive predictor of outcomes in STEMI patients. We sought to evaluate potential variables associated with the risk of suboptimal TIMI flow after PCI in patients with anterior wall STEMI. METHODS: We evaluated 107 patients admitted to our hospital between 1 January 2019 and 31 December 2021 with a diagnosis of anterior wall STEMI treated with primary PCI. RESULTS: Suboptimal TIMI flow grade (≤2) after PCI occurred in 14 (13%) patients while grade 3 was found in 93 (87%) of them presenting with anterior wall STEMI. Failure to achieve optimal TIMI 3 flow grade after PCI was associated with lower TIMI grade prior to PCI (OR 0.5477, 95% CI 0.2589-0.9324, p = 0.02), greater troponin concentration before (OR 1.0001, 95% CI 1-1.0001, p = 0.0028) and after PCI (OR 1.0001, 95% CI 1-1.0001, p = 0.0452) as well as lower mean minimal systolic blood pressure (OR 0.9653, 95% CI 0.9271-0.9985, p = 0.04). CONCLUSIONS: Among predictors of suboptimal TIMI flow grade after PCI, we noted lower TIMI grade flow pre-PCI, greater serum troponin concentrations in the periprocedural period and lower mean minimal systolic blood pressure.
RESUMO
I n t r o d u c t i o n: Seasonal variation has been observed for bacterial and viral infections (e.g., COVID-19 [1]), but also for numerous cardiac problems. However, little information is available on the seasonality of infectious endocarditis (IE), a rare disease that is usually linked to a bacterial origin. Data from the Polish population are lacking. Materials and M e t h o d s: Our retrospective study focused on the identification of patients with IE, who were hospitalized at the University Hospital in Krakow between 2005-2022. For this purpose, we searched the medical records system using the ICD-10 code. We decided to divide our patients into four groups (winter, spring, summer, autumn), based on the date of admission to the hospital. Comparison of the distribution of IE incidents by season was performed with the ch2 test. R e s u l t s: One hundred and ten patients were included in the study (median age 62.5 years (range 20-94), 72 men (65.45%)). The left native valve IE was diagnosed in 49% of the patients, the prosthetic valve IE in 16%, the right valve IE in 27% and the implantable cardiac electronic devices IE in 12% of the subjects. The outcomes comprised of cardiac surgery (n = 53), embolism (n = 16), death (n = 15) and metastatic infections (n = 5). No differences in the incidence of IE by season were observed. C o n c l u s i o n s: In the preliminary observation of IE cases of patients admitted to the University Hospital in Krakow, Poland no seasonal pattern of IE was detected. Therefore, IE should be taken into account in the differential diagnosis at any time of the year.

(1) Background: Since the treatment of chronic total occlusion (CTO) with percutaneous coronary intervention (PCI) is associated with high procedural complexity, it has been suggested to use a multi-operator approach. This study was aimed at evaluating the procedural outcomes of single (SO) versus dual-operator (DO) CTO-PCI approaches. (2) Methods: This retrospective analysis included data from the Polish Registry of Invasive Cardiology Procedures (ORPKI), collected between January 2014 and December 2020. To compare the DO and SO approaches, propensity score matching was introduced with equalized baseline features. (3) Results: The DO approach was applied in 3604 (13%) out of 27,788 CTO-PCI cases. Patients undergoing DO CTO-PCI experienced puncture-site bleeding less often than the SO group (0.1% vs. 0.3%, p = 0.03). No differences were found in the technical success rate (successful revascularization with thrombolysis in myocardial infarction flow grade 2/3) of the SO (72.4%) versus the DO approach (71.2%). Moreover, the presence of either multi-vessel (MVD) or left main coronary artery disease (LMCA) (odds ratio (OR), 1.67 (95% confidence interval (CI), 1.20-2.32); p = 0.002), as well as lower annual and total operator volumes of PCI and CTO-PCI, could be noted as factors linked with the DO approach. (4) Conclusions: Due to the retrospective character, the findings of this study have to be considered only as hypothesis-generating. DO CTO-PCI was infrequent and was performed on patients who were more likely to have LMCA lesions or MVD. Operators collaboratively performing CTO-PCIs were more likely to have less experience. Puncture-site bleeding occurred less often in the dual-operator group; however, second-operator involvement had no impact on the technical success of the intervention.
RESUMO
BACKGROUND: Fractional flow reserve (FFR) and non-hyperemic resting pressure ratios, such as instantaneous wave-free ratio (iFR) and resting full-cycle ratio (RFR), are recommended for evaluating the significance of angiographically intermediate coronary stenoses. Despite their usefulness, approximately 20% of assessed lesions exhibit discordance between FFR and iFR/RFR. AIMS: The role of sex in this discrepancy remains uncertain; thus, we aimed to investigate its impact on the discordance between FFR and iFR/RFR. METHODS: We reviewed 417 consecutive intermediate stenotic lesions from 381 patients, stratified by sex and assessed with both FFR and iFR/RFR. FFR ≤0.80 and iFR/RFR ≤0.89 were considered positive for ischemia. RESULTS: Of the 381 patients, 92 (24.1%) were women. Women were older, had a lower estimated glomerular filtration rate (eGFR), higher ejection fraction, and were more likely to have peripheral artery disease than men. Median FFR and iFR/RFR values were lower in men than in women (FFR 0.86 vs. 0.80; P <0.001; iFR 0.92 vs. 0.90; P = 0.049). However, overall discordance prevalence was similar for both sexes (20.6% vs. 15.1%; P = 0.22). In men, eGFR, insulin-treated diabetes mellitus, and arterial hypertension were predictors of positive FFR | negative iFR/RFR discordance, while eGFR, insulin-treated diabetes mellitus, atrial fibrillation, and chronic obstructive pulmonary disease were predictors of negative FFR | positive iFR/RFR discordance. No factors associated with either discordance were identified in women. CONCLUSIONS: FFR and iFR/RFR results indicating significant ischemia were more common in men than women when assessing intermediate coronary stenoses. Nevertheless, sex did not predict discordant results.

The degree of platelet inhibition in patients undergoing dual antiplatelet therapy (DAPT) affects cardiovascular outcomes after acute coronary syndromes (ACS) and/or percutaneous coronary intervention. Our aim was to search for correlates of residual ex vivo platelet reactivity and circulating soluble P-selectin (sP-selectin), an index of in vivo platelet activation, in patients being treated by DAPT with ticagrelor. Adenosine diphosphate (ADP)-induced platelet aggregability (by multiple electrode aggregometry) and plasma sP-selectin were estimated in 62 stable post-ACS subjects (46 men and 16 women; mean age: 64 ± 10 years; 30 with type 2 diabetes (T2DM)) undergoing maintenance DAPT with ticagrelor and aspirin. These patients did not exhibit heart failure or other relevant coexistent diseases except for properly controlled T2DM, mild renal insufficiency, and hypertension. We also assessed this in 64 subjects on clopidogrel-based DAPT matched for age, sex, and T2DM status. ADP-induced platelet aggregation was below the optimal levels (190-460 arbitrary units (AU) * min) in most patients receiving ticagrelor-based DAPT, especially in those with below-median (<1.9 mmol/L) serum concentrations of low-density lipoprotein cholesterol (LDL-c) (128 ± 61 vs. 167 ± 73 AU * min for below-median and above-median LDL-c, respectively, p = 0.025). In contrast, platelet reactivity did not differ by LDL-c on clopidogrel-based DAPT (246 ± 101 vs. 268 ± 108 AU * min for below-median and above-median LDL-c, respectively, p > 0.4). Plasma sP-selectin was found to be unrelated to serum LDL-c when receiving DAPT with ticagrelor (p > 0.4) or clopidogrel (p > 0.8). In conclusion, our preliminary observational study suggests the association of lower residual ex vivo platelet aggregability with better LDL-c control in patients undergoing ticagrelor-based maintenance DAPT, which does not appear to be reflected by plasma sP-selectin. Whether the serum LDL-c level should be considered among the factors affecting the degree of platelet inhibition for those treated with ticagrelor-based DAPT needs to be investigated in larger studies.
RESUMO
BACKGROUND: Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have demonstrated improvement in the clinical outcome of patients undergoing percutaneous coronary intervention (PCI). AIMS: We aimed to examine the frequency of implementing OCT and IVUS during coronary angiography (CA) and PCI in everyday practice in Poland. Factors related to the more common choice of these imaging techniques were determined. METHODS: Data from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI) were procured for analysis. Between January 2014 and December 2021, we extracted data on 1 452 135 CAs, 11 710 using IVUS (0.8%) and 1471 with OCT (0.1%) and 838 297 PCIs, 15 436 with IVUS (1.8%) and 1680 with OCT (0.2%). We assessed the determining factors for applying IVUS and OCT via multiple regression logistics models. RESULTS: The frequency of applying IVUS during CAs and PCIs increased significantly between the years 2014 and 2021. In 2021, it reached 1.54% for CAs and 4.42% for PCIs, while for OCT, there was a rise regarding the CA group, namely 0.13% in 2021, and, in the PCI group, 0.43%. Age was one of the factors significantly associated with the frequency of using IVUS/OCT during CA/PCI, which was confirmed by multivariate analysis (Odds ratio: 0.981 for IVUS and 0.973 for OCT use with PCI). CONCLUSION: The frequency at which IVUS and OCT were used has undergone a significant increase in previous years. This increase can be largely attributed to the current reimbursement policies. Further improvement is required for this frequency to be at a satisfactory level.

INTRODUCTION: Current guidelines recommend physiological evaluation of borderline coronary artery stenoses using hyperemic (fractional flow reserve [FFR]) and nonhyperemic (instantaneous wavefree ratio [iFR] and resting fullcycle ratio [RFR]) methods. However, comorbidities, such as diabetes mellitus (DM), may influence the results of the assessment. OBJECTIVES: We sought to investigate the impact of DM and insulin treatment on the discordance between FFR and iFR/RFR. PATIENTS AND METHODS: A total of 417 intermediate stenoses in 381 patients underwent FFR and iFR/RFR assessment. FFR lower than or equal to 0.8 and iFR/RFR lower than or equal to 0.89 indicated significant ischemia. The patients were categorized based on DM diagnosis and insulin treatment status. RESULTS: Of the 381 patients, 154 (40.4%) had DM. Among these, 58 patients (37.7%) received insulin treatment. Diabetic patients had higher body mass index and glycated hemoglobin levels, and lower ejection fraction. FFR and iFR/RFR analyses were conducted in 417 vessels with available measurements for both tests. A good correlation between FFR and iFR/RFR was confirmed in both diabetic (R = 0.77) and nondiabetic (R = 0.74) patients. Discordance between FFR and iFR/RFR occurred in approximately 20% of cases, and the frequency of discordance was not affected by the diabetic status. However, insulintreated DM was independently associated with a higher risk of negative FFR and positive iFR/RFR discordance (odds ratio, 4.61; 95% CI, 1.38-15.4; P = 0.01). Also, the optimal cutoff value for FFR identifying significant ischemia in DM patients treated with insulin was higher (0.84) than the generally recommended value. CONCLUSIONS: The rate of FFR and iFR/FFR discordance was similar regardless of the diabetes status, and insulintreated DM was associated with an increased risk of negative FFR and positive iFR/RFR discordance.

Introduction: Standard transthoracic echocardiography (TTE) often is not sufficient to properly visualize the geometry of the left ventricle. One of the clinical imaging modalities that can be used for this purpose is contrast-enhanced, electrocardiologically gated cardiac computed tomography (CT). Aim: To compare cardiac CT and TTE as tools for assessing geometry and function of the left ventricle in patients with severe aortic stenosis. Material and methods: We analyzed 58 consecutive patients (43.1% males, mean age 81.4 ±6.0 years) with severe aortic stenosis, who underwent both cardiac CT and TTE. Results: Left ventricle major axis length is significantly longer in CT than in TTE (81.5 ±11.7 mm vs. 74.6 ±13.5 mm, p = 0.004). No difference was found in end-systolic left ventricle volume between the two imaging methods, while end-diastolic volume of the left ventricle was significantly larger when measured in CT than in both 2D biplane and 3D triplane TTE. The stroke volume was not different between the 2D biplane TTE and CT. No significant difference was found between CT and TTE in the calculation of ejection fraction and LV mass/indexed LV mass (p > 0.05). Conclusions: The use of three-dimensional postprocessing provides a very accurate image of heart structures in CT, which in some aspects may significantly differ from the values estimated by TTE.
RESUMO
In the era of potent P2Y12 inhibitors, according to current guidelines, treatment with glycoprotein IIb/IIIa inhibitors (GPIs) should be limited to bail-out and/or highly thrombotic situations. Similarly, the recommendation for aspiration thrombectomy (AT) is downgraded to very selective use. We examine the prevalence, and predictors of GPI and AT use in STEMI patients referred to primary percutaneous coronary intervention (PCI). Data on 116,873 consecutive STEMI patients referred to primary PCI in Poland between 2015 and 2020 were analyzed. GPIs were administered in 29.3%, AT was used in 11.6%, and combined treatment with both in 6.1%. There was a mild trend toward a decrease in GPI and AT usage during the analyzed years. On the contrary, there was a rapid growth of the ticagrelor/prasugrel usage rate from 6.5 to 48.1%. Occluded infarct-related artery at baseline and no-reflow during PCI were the strongest predictors of GPI administration (OR 2.3; 95% CI 2.22-2.38 and OR 3.47; 95% CI 3.13-3.84, respectively) and combined usage of GPI and AT (OR 4.4; 95% CI 4.08-4.8 and OR 3.49; 95% CI 3.08-3.95 respectively) in a multivariate logistic regression model. Similarly, the administration of ticagrelor/prasugrel was an independent predictor of both adjunctive treatment strategies. In STEMI patients in Poland, GPIs are selectively used in one in four patients during primary PCI, and the combined usage of GPI and AT is marginal. Despite the rapid growth in potent P2Y12 inhibitors usage in recent years, GPIs are selectively used at a stable rate during PCI in highly thrombotic lesions.

Guidelines recommend using hyperemic (FFR) and non-hyperemic (iFR/RFR) methods of evaluating coronary artery stenoses in patients with coronary artery disease. However, in some cases, achieved results indicating significant ischemia may differ between those methods. Thus, we sought to identify predictors of such a discrepancy. Data were collected on all consecutive patients with chronic coronary syndrome hospitalized between 2020 and 2021. For 279 patients (417 vessels), results for both FFR and iFR/RFR were available. Values of ≤0.80 for FFR and ≤0.89 for iFR/RFR were considered positive for ischemia. Discordant measurements of FFR and iFR/RFR were observed in 80 (19.2%) patients. Atrial fibrillation was the only predictor of the overall FFR and iFR/RFR discordance - OR (95%CI) 1.90 (1.02-3.51); p = 0.040. The chance of positive FFR and negative iFR/RFR decreased independently with age - OR (95%CI) 0.96 (0.93-0.99); p = 0.024. On the contrary, insulin-treated diabetes mellitus was the predictor of negative FFR and positive iFR/RFR discrepancy - OR (95%CI) 4.61 (1.38-15.40); p = 0.013. In everyday clinical practice, iFR/FFR correlates well with FFR. However, discordance between these methods is quite common. Physicians should be aware of the risk of such discordance in patients with atrial fibrillation, advanced age, and insulin-treated diabetes mellitus.
RESUMO
BACKGROUND: Based on the clinical outcomes of patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), treated with primary percutaneous coronary intervention (pPCI), this study intended to assess mortality and major adverse cardiac and cerebrovascular event (MACCE) rates according to duration of pain-to-balloon (PTB) time and type of MI. METHODS: This is a retrospective cohort study based on the prospectively collected ORPKI registry which covers PCIs performed in Poland chosen between January 2014 and December 2017. Under assessment were 1,994 STEMI and 923 NSTEMI patients. Study endpoints included mortality and MACCE rates (in-hospital, 30-day, 12- and 36-month). Predictors of all-cause mortality in the overall group, STEMI and NSTEMI were assessed by multivariable analysis. RESULTS: Kaplan-Meier survival curve analysis did not reveal significant differences between the STEMI and NSTEMI group for all-cause mortality or MACCE at the 36-month follow-up. While in the long PTB time group, MACCE rate was significantly greater in STEMI patients when compared to NSTEMI (p = 0.004). Among STEMI patients, the short, medium and long PTB time groups differed significantly in the rate of all-cause mortality (p = 0.006) and MACCE (p = 0.04) at 1,095 days of follow-up, which were the greatest in the long PTB time group. CONCLUSIONS: Before considering the length of PTB time, there were no statistically significant differences in mortality or MACCE frequency between the STEMI and NSTEMI group at 36-month follow-up. Longer PTB times are related to significantly greater mortality at the 36-month follow-up in the STEMI, but not in the NSTEMI group.
