Background Both unstable angina and non-ST-segment elevation myocardial infarction (NSTEMI) are still classified together in non-ST-elevation acute coronary syndromes despite the fact they substantially differ in both clinical profile and prognosis. The aim of the present study was to evaluate contemporary clinical characteristics and outcomes of unstable angina patients after percutaneous coronary intervention (PCI) in comparison with stable angina and NSTEMI in Swietokrzyskie District of Poland in years 2015–2017. Methods A total of 7187 patients after PCI from ORPKI Registry (38% with diagnosis of unstable angina) were included into the analysis. Impact of clinical presentation (unstable angina, stable angina, NSTEMI, STEMI) on three-year outcomes were determined. Results Unstable angina patients were older than stable angina but younger than NSTEMI individuals. In unstable angina group, the percentage of previous myocardial infarction (MI), PCI or coronary artery bypass grafting (CABG) was the highest among all analyzed groups. In three-year observation, the risk of death as well as MI and MACE in unstable angina after PCI was higher than stable angina angina but considerably lower than in the NSTEMI group. Multivariate analysis confirmed that prognosis in NSTEMI was substantially worse in comparison with unstable angina [relative risk (RR) 1.365, 95% confidence interval (CI): 1.126–1.655, P = 0.0015]. On the contrary in unstable angina and stable angina patients, the impact of diagnosis on mortality risk was similar (RR 1.189, 95% CI: 0.932–1.518, P = 0.1620). Parallel results were observed in respect of MI and MACE. Independent predictors of death or MACE were: age, kidney disease, hypertension, diabetes, previous stroke or previous PCI. Conclusion Three-year prognosis in unstable angina was considerable better in comparison with NSTEMI. On the contrary, after adjustment for baseline differences, the outcomes (death, MI, MACE) in unstable angina and stable angina patients were comparable.

WHAT THIS PAPER ADDS This is the first study on iatrogenic femoral pseudoaneurysms, treated with ultrasound guided thrombin injection (UGTI), to address the issue of the UGTI dosing protocol. The main clinical implication of this study is that fractionated administration of smaller thrombin doses might be preferred to the standard dosing protocol, as this seems to be at least equally effective and associated with a significantly lower complication rate and reduced thrombin dose.Objective: Ultrasound guided thrombin injection (UGTI) is a minimally invasive method of treatment for iatrogenic post-catheterisation femoral pseudoaneurysms (psAs). The optimal dosing protocol for UGTI has not been established. The aim of the study was to compare the success and complication rates between two different dosing protocols (the most commonly used "standard dose protocol" and the "low dose protocol," which is the fractionated administration of smaller thrombin doses of up to 40 IU every 15 s) in patients with a psA with sac volume of !1 mL. Methods: This was a retrospective cohort study, and the analysis was performed using a case matching approach based on propensity score. From June 2004 to August 2018, 384 patients who underwent femoral puncture for transcatheter procedures were diagnosed with femoral psA with a sac volume of !1 mL and qualified for UGTI. The patients' mean age was 68 (AE10.6) years and there were 217 (56.5%) women. To compare protocols, 124 patients treated according to the low dose protocol were nearest neighbour matched according to their propensity score to 124 patients treated according to the standard dose protocol. Results: The overall success rate (99.2% vs. 98.4%; p ¼ 1) and success rate of the first UGTI attempt (87.1% vs. 86.3%; p ¼ .85) did not differ between the low dose and standard dose groups. Complications were less common in the low dose group (7.3% vs. 16.1%; p ¼ .03) and the median total amount of thrombin used for procedures was smaller in the low dose group (120 IU vs. 195 IU; p ¼ .01). Conclusions: In patients with femoral psA with sac volume of !1 mL, the use of the low dose protocol seemed to be equally effective as the standard dose protocol and was associated with a lower complication rate and reduced thrombin dose.

Sex differences in STEMI patients were narrowing from 2005 to 2011 in Poland. However, more attention needs to be focused on increasing smoking prevalence, the longer times from symptoms onset to hospital admission in women and the lower frequencies of the use of an invasive treatment strategy in older women, and their worse in-hospital outcomes.

Coronary artery disease complicates only 0.01% of all pregnancies. For this reason, more exhaustive data on the management of such cases is lacking. Even guidelines on management of cardiovascular disease in pregnant women are scarce focusing mainly on acute myocardial infarction. This is a complex issue involving thorough evaluation of cardiovascular status in each pregnant woman, assessment of risk for developing coronary complications, and close cooperation with obstetric teams. Safety data on typical cardiac drugs such as statins, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or novel antiplatelet drugs are also scarce and their effect on the developing human fetus is not well understood. We present a review on the management of such patients.

Background Peak left atrial longitudinal strain (PALS) can help identify left atrial appendage thrombus (LAAT) in patients with atrial fibrillation. Nevertheless, few studies have been performed in patients in sinus rhythm without established indications for anticoagulation but with increased risk of LAAT, such as heart failure (HF) with severe left ventricular systolic dysfunction patients. The primary aim of this study was to identify clinical and transthoracic echocardiography predictors of LAAT in HF patients with very low left ventricular ejection fraction and sinus rhythm. The secondary objective was to analyze frequencies and predictors of a composite clinical endpoint of death or hospitalization for ischemic stroke. Methods We included 63 patients with HF, left ventricular ejection fraction < 25%, sinus rhythm at presentation, no history of atrial fibrillation, and without any established indications for anticoagulation. We determined whether clinical and transthoracic echocardiography parameters, including left atrial strain analysis, predicted LAAT. Transesophageal echocardiography was performed in all patients. When LAAT was detected, anticoagulation was recommended. The participants were followed for a median of 28.6 months (range 4–40) to determine the composite endpoint. Results LAAT was found in 20 (31.7%) patients. Global PALS was the best independent predictor of LAAT in univariate and multivariate logistic regression analyses (Gini coefficient 0.65, area under the receiver-operating characteristic curve 0.83). A global PALS value below 8% was a good discriminator of LAAT presence (odds ratio 30.4, 95% CI 7.2–128, p <  0.001). During follow-up, 18 subjects (28.6%) reached the composite clinical endpoint. CHA2DS2-VASc score, use of angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers, and body surface area were significant predictors for the composite endpoint of death or hospitalization for ischemic stroke in the multivariate regression model. Conclusions LAAT was relatively common in our group of HF patients and PALS has shown prognostic potential in LAAT identification. Further research is needed to determine whether initiation of anticoagulation or additional screening supported by PALS measurements will improve clinical outcomes in these patients.

Introduction: Ultrasound-guided thrombin injection (UGTI) is the preferred treatment of pseudoaneurysms (psA). The potential risk of complications increases with the number of UGTI treatments needed for complete psA obliteration. Identification of risk factors for recurrent psA is needed. Material and methods: In total, 508 patients with femoral artery psA underwent UGTI, followed by ultrasound examination repeated twice, at 1-week intervals, to assess UGTI effectiveness. In cases of psA recurrence, the procedure was repeated. Clinical and ultrasound data were prospectively collected. Results: The psA recurrence occurred in 76 (15%) patients. UGTI was repeated twice in 49 (64%), three times in 15 (20%) and more than three times in 12 (16%) patients. The median thrombin dose was 150 IU (80-250 IU), and was lower in initial procedures than repeated UGTI (p = 0.025). The median psA volume was 2.26 ml (0.86-5.47 ml). The median length of the communicating channel was 4 mm (0-12 mm). A time interval between vessel catheterization and UGTI greater than 7 days (p < 0.001), a late to early velocity index (LEVI) of < 0.2 identified during the outflow phase (p < 0.001), a psA volume > 5 ml (p = 0.032), and a short communicating channel between the psA and the artery (p = 0.037) predicted psA recurrence. Antiplatelet and anticoagulant agents did not increase the risk. Conclusions: The LEVI and time interval between artery cannulation and UGTI treatment are strong parameters identifying patients at risk of psA recurrence. The psA volume and communicating channel length are less substantial risks, but still significant. Concomitant antiplatelet and anticoagulant therapy do not affect the success rate of UGTI.

Introduction:The aim of this study is to estimate how much of the recent decrease in mortality among patients with myocardial infarction with ST-segment elevation (STEMI) can be attributed to improved treatment strategies, and how much it is related to changes in baseline clinical characteristics, and to compare these findings for men and women. Material and methods: This was a retrospective analysis of 32,790 patients with STEMI from the Polish Registry of Acute Coronary Syndromes PL-ACS hospitalised in 2005 and 2011. Changes in treatment strategies including pharmacotherapy were analysed. Observed in-hospital and 12-month mortality rates were compared with the outcomes in the groups matched on the propensity scores. Results: There was a substantial improvement in STEMI patient management between 2005 and 2011 in Poland. It included greater use of percutaneous coronary interventions and other guideline-based adjunctive therapies, and it was associated with a significant decline in in-hospital mortality. Relative 12-month mortality reduction rates were less pronounced and more related to changes in patients' clinical characteristics. Higher mortality risk reductions were observed in women and were driven by relatively more positive changes in their baseline risk profiles when compared to men. Conclusions: The progress in the treatment strategies has helped to achieve better survival rates in STEMI patients. However, the ongoing changes in clinical characteristics of patients also played an important role, especially in women. Clinicians should focus on modifiable risk factors and post-discharge management to possibly prolong the positive aspects of in-hospital efforts.

Ultrasound-guided thrombin injection (UGTI) is often the first-line treatment for iatrogenic post-catheterization pseudoaneurysms (psA). There are also first reports of the use of biologically derived tissue glues (TG) instead of sole thrombin especially when UGTI was unsuccessful or in case of psA recurrence. Previously, we have established that a late to early velocity index (LEVI) < 0.2 could be a predictor of an increased risk of psA recurrence after standard UGTI. In this paper, we report our first experiences when the choice of the first-line treatment method was based on LEVI assessment. From May 2017 till January 2020 we included 36 patients with psA. Of them, 10 had LEVI < 0.2 and they underwent ultrasound-guided tissue glue injection (UGTGI) with biological TG and 26 had LEVI > 0.2 and they underwent UGTI. The injection set containing human thrombin and fibrinogen was used for UGTGI. Bovine thrombin was used for UGTI. The success rate was 100% and no psA recurrence was detected during a 2-week follow-up. It was significantly better when compared to the expected recurrence rates based on our previous 14 years of experience (0% vs. 13%, p = 0.01). All complications (10% in the UGTGI group and 15% in the UGTI group) were mild and transient and included clinical symptoms of paresthesia, numbness, tingling, or pain. Their rates were comparable to the rates we previously reported. No significant differences in other characteristics were observed. The approach to choose the first-line treatment method for iatrogenic psA based on LEVI is encouraging. It may increase the success rate and avoid unnecessary repetition of the procedure, without increasing complication rate while keeping costs of the procedure reasonable.
