Multicenter registry of Impella-assisted high-risk percutaneous coronary interventions and cardiogenic shock in Poland (IMPELLA-PL).

BACKGROUND: Impella is a percutaneous mechanical circulatory support device for treatment of cardiogenic shock (CS) and high-risk percutaneous coronary interventions (HR-PCIs). IMPELLA-PL is a national retrospective registry of Impella-treated CS and HR-PCI patients in 20 Polish interventional cardiological centers, conducted from January 2014 until December 2021. AIMS: We aimed to determine the efficacy and safety of Impella using real-world data from IMPELLA-PL and compare these with other registries. METHODS: IMPELLA-PL data were analyzed to determine primary endpoints: in-hospital mortality and rates of mortality and major adverse cardiovascular and cerebrovascular events (MACCE) at 12 months post-discharge. RESULTS: Of 308 patients, 18% had CS and 82% underwent HR-PCI. In-hospital mortality rates were 76.4% and 8.3% in the CS and HR-PCI groups, respectively. The 12-month mortality rates were 80.0% and 18.2%, and post-discharge MACCE rates were 9.1% and 22.5%, respectively. Any access site bleeding occurred in 30.9% of CS patients and 14.6% of HR-PCI patients, limb ischemia in 12.7% and 2.4%, and hemolysis in 10.9% and 1.6%, respectively. CONCLUSIONS: Impella is safe and effective during HR-PCIs, in accordance with previous registry analyses. The risk profile and mortality in CS patients were higher than in other registries, and the potential benefits of Impella in CS require investigation.

Management of myocardial infarction complicated by cardiogenic shock: Expert opinion of the Association of Intensive Cardiac Care and Association of Cardiovascular Interventions of the Polish Society of Cardiology.

Despite significant advances in interventional cardiology and mechanical circulatory support (MCS) techniques, outcomes for patients with myocardial infarction (MI) complicated by cardiogenic shock (CS) remain suboptimal. This expert consensus aims to provide information on the current management of patients with MI complicated by CS in Poland and to propose solutions, including systemic ones, for all stages of care. The document uses data from the Polish PL-ACS Registry of Acute Coronary Syndromes, which includes records of more than 820 000 hospital admissions. We describe the role of medical rescue teams, highlighting the necessity to expand their range of competencies at the level of prehospital care. We emphasize the importance of treating the underlying cause of CS and direct patient transfer to centers capable of performing percutaneous coronary interventions. We present current recommendations of scientific societies on MCS use. We underline the role of the Cardiac Shock Team in the management of patients with MI complicated by CS. Such teams should comprise an interventional cardiologist, a cardiothoracic surgeon, and an intensive care physician. Patients should be transferred to highly specialized CS centers, following the example of so-called Cardiac Shock Care Centers described in some other countries. We propose criteria for the operation of such centers Other important aspects discussed in the document include the role of rehabilitation, multidisciplinary care, and long-term follow-up of treatment outcomes. The document was developed in cooperation with experts from different scientific societies in Poland, which illustrates the importance of interdisciplinary care in this patient population.

Modern and Non-Invasive Methods of Fat Removal.

Adipocytes accumulate triacylglycerols as an energy store, thereby causing an increase in the adipose tissue volume. Weight gain can be prevented through damage to the adipocyte structure or an increase in the body's metabolic rate. Commonly used methods to disintegrate the cell membrane of adipocytes include injection lipolysis, cryolipolysis, ultrasonic lipolysis, radiofrequency lipolysis, laser lipolysis, carboxytherapy, and lipolysis using an electromagnetic field. The names of these methods suggest which substances are being used, and their main advantages are a very low invasiveness, as well as effectiveness. However, new discoveries in medicine, along with individuals' desire to improve their appearance, have resulted in numerous studies on more ways of reducing body fat. Great potential is seen in beige adipocytes, which can be transformed, i.e., "recruited" from white adipocytes, or synthesized de novo; they also show thermogenic properties. One of the stimuli inducing the formation of beige adipocytes is cold and B3-adrenergic stimulation. Based on these findings, the researchers created, for example, cooling clothing. Additionally, curcumin and natural anthocyanins have proven to be helpful in the treatment of obesity and diabetes, by stimulating the secretion of glucagon-like peptide-1, and inducing the formation of beige adipocytes. Another study showed that the conversion of white adipose tissue is indirectly influenced by interleukin-6 secreted by the muscles, the expression of which is increased in people actively exercising. Moreover, there is potential in adenosine analogs, fenoldopam, rhubarb, the herbal extract Ephedra sinica Stapf, electroacupuncture simulation, and the drug CBL-514. Despite knowledge and experience, the ideal method for a quick and noticeable, but safe and non-invasive reduction of body fat has not been found yet. The research conducted nowadays may bring us closer to the development of a universal method, and turn out to be a breakthrough in the fight against overweight and obesity.

Innovative Reports on the Effects of Anabolic Androgenic Steroid Abuse-How to Lose Your Mind for the Love of Sport.

Anabolic-androgenic steroids (anabolic-androgenic steroids, AAS) are testosterone-derived compounds whose popularity and use are constantly growing. Chronic use of AAS leads to many hormonal and metabolic disorders in the human body, which often lead to permanent health damage. Changes affect the following systems: cardiovascular, musculoskeletal, reproductive, digestive, and nervous. We decided to collect the existing knowledge in the literature and enrich it with the latest research reports in the field of degenerative effects of AAS on the nervous system. The work aimed to increase public awareness of the dangers and consequences of AAS use and improve it with the latest research on the neurodegenerative effects of AAS. We hope that our work will contribute to raising public awareness and reducing the use of AAS.

Factors affecting short- and long-term survival of patients with acute coronary syndrome treated invasively using intravascular ultrasound and fractional flow reserve: Analysis of data from the Polish Registry of Acute Coronary Syndromes 2017-2020.

BACKGROUND: Intravascular ultrasound (IVUS) and fractional flow reserve (FFR) are invasive procedures increasingly used in treating acute coronary syndrome (ACS). AIMS: This study aimed to evaluate the frequency of IVUS and FFR use in patients with ACS in Poland and to assess the safety of these procedures as well as their impact on short- and long-term survival. METHODS AND RESULTS: This retrospective study included 103849 patients enrolled in the Polish Registry of Acute Coronary Syndromes in 2017-2020. IVUS was performed in 1727 patients, FFR in 1537 patients, and both procedures in 37 patients. The frequency of performing FFR in ACS patients increased over the years from 1.3% to 1.8% (P <0.0001) and IVUS from 1.7% to 2.3% (P <0.0001). In the FFR and/or IVUS group, a similar incidence of stroke, reinfarction, target vessel revascularization, and major bleeding was observed while in-hospital mortality was lower (0% for IVUS + FFR vs. 0.9% for FFR vs. 2.3% for IVUS vs. 3.7 for no procedure; P <0.0001). FFR and IVUS did not affect the 30-day and one-year prognosis. CONCLUSION: In recent years, the number of FFR and IVUS procedures performed in patients with ACS in Poland has increased. There was lower in-hospital mortality in the FFR and/or IVUS group in ACS patients, and no differences in the incidence of stroke, reinfarction, target vessel revascularization, and major bleeding were observed. Performing FFR and IVUS in ACS patients does not significantly affect 30-day or one-year mortality.

Transcatheter Versus Surgical Valve Replacement: A 24-months Propensity-matched Analysis of the SILCARD Registry.

BACKGROUND: Data concerning the comparison between transcatheter aortic valve implantation and surgical aortic valve replacement in a real-world setting are scarce and in Central and Eastern Europe no such data exist. In this study, we aimed at analyzing retrospectively the characteristics and outcome of patients with aortic stenosis treated either with surgical aortic valve replacement or transcatheter aortic valve implantation between 2006 and 2016 in the Silesian Province, Poland in a representative real-world cohort. METHODS: In the Silesian Cardiovascular Database we retrospectively identified 5186 patients who received either transcatheter aortic valve implantation or surgical aortic valve replacement in 1 of 3 tertiary cardiovascular centers. Baseline characteristics, including relevant clinical history, and outcomes were compared before and after propensity-score matching of both groups, with 348 pairs of patients constituting the propensity-matched study cohort. The primary end-point was 24-month all-cause mortality. RESULTS: Preoperative characteristics of propensity-matched groups were similar. There was no difference between transcatheter aortic valve implantation and surgical aortic valve replacement groups with respect to the death rate at 2 years (19.9% vs. 15.6%; P =.479). In the transcatheter aortic valve implantation group, cardiac resynchronization therapy devices were more frequently implanted after the procedure (3.7% vs. 0.0, P <.001). The groups had similar rates of myocardial infarction, stroke, and re-hospitalization. Hospital stay in the matched groups was shorter after transcatheter aortic valve implantation: 14.1 versus 15.7 days (P <.001). CONCLUSIONS: At 24 months, transcatheter aortic valve implantation patients had similar outcomes as surgical aortic valve replacement except for a higher rate of cardiac resynchronization therapy device implantation and shorter hospital stay.

Annual operator volume among patients treated using percutaneous coronary interventions with rotational atherectomy and procedural outcomes: Analysis based on a large national registry.

BACKGROUND: Low operator and institutional volume are associated with poorer procedural and long-term clinical outcomes in the general population of patients treated with percutaneous coronary interventions (PCI). AIM: To assess the relationship between operator experience and procedural outcomes of patients treated with PCI and rotational atherectomy (RA). METHODS: Data for conducting the current analysis were obtained from the national registry of percutaneous coronary interventions (ORPKI) maintained in cooperation with the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society. The study covers data from January 2014 to December 2020. RESULTS: During the investigated period, there were 162 active CathLabs, at which 747,033 PCI procedures were performed by 851 operators (377 RA operators [44.3%]). Of those, 5188 were PCI with RA procedures; average 30 ± 61 per site/7 years (Me: 3; Q1-Q3: 0-31); 6 ± 18 per operator/7 years (Me: 0; Q1-Q3: 0-3). Considering the number of RA procedures annually performed by individual operators during the analyzed 7 years, the first quartile totaled (Q1: < =2.57), the second (Q2: < =5.57), and the third (Q3: < =11.57), while the fourth quartile was (Q4: > 11.57). The maximum number of procedures was 39.86 annually per operator. We demonstrated, through a nonlinear relationship with annualized operator volume and risk-adjusted, that operators performing more PCI with RA per year (fourth quartile) have a lower number of the overall periprocedural complications (p = 0.019). CONCLUSIONS: High-volume RA operators are related to lower overall periprocedural complication occurrence in patients treated with RA in comparison to low-volume operators.

Transradial Interventions at the Forefront of Innovation.

Interventional cardiology has witnessed tremendous changes over the years from a mainly diagnostic approach in an elective population to therapeutic strategies in critically ill patients. Currently, we can treat a broad spectrum of coronary artery, peripheral artery, and structural heart diseases with less invasive, percutaneous approaches that we did not anticipate to be possible just a decade ago. It is certain that the interventional techniques will see further development and we will be able to treat by percutaneous methods more conditions previously thought beyond our reach. Regardless of the advances in catheter-based diagnostic and therapeutic techniques, one thing remains constant. They all require vascular access. And, vascular access is the first technical part of any percutaneous cardiovascular procedure that can determine its overall success. High-quality data together with the availability of training courses for interventional cardiologists and fellows-in-training ensure systematic use of the transradial approach (TRA) which has demonstrated a considerable benefit compared to transfemoral approach both in chronic and acute coronary syndromes. Constant improvement of TRA techniques will further facilitate transradial endovascular and structural interventions, and the growing use for high-risk and complex percutaneous coronary interventions. A continuously growing body of evidence is focused on surpassing current TRA limitations (specifically radial artery occlusion) and expanding alternative vascular accesses such as transulnar approach or distal TRA ("snuff-box" technique). Should this downsizing trend continue, we could see a further paradigm shift toward using the snuff-box technique.

Factors associated with cardiac allograft vasculopathy after heart transplantation.

Introduction: Cardiac allograft vasculopathy (CAV) is a major threat to long-term survival after heart transplantation (HT). Aim: To determine factors associated with CAV detection in patients after HT. Material and methods: We analyzed 299 consecutive patients after HT who underwent routine visits at our institution between 2016 and 2018. Human interleukin 33 (IL-33) and suppression of tumorigenicity 2 (ST2) were measured by sandwich enzyme-linked immunosorbent assay with a commercially available kit (Human ST-2 and IL-33 ELISA, SunRedBio Technology Co, Ltd, Shanghai, China). Results: The patients' median age was 59.00 years, and 74.2% were men. The frequency of CAV was 47.5%. Multivariable logistic regression analysis showed that IL-33 (odds ratio (OR) = 1.044 (1.029-1.059), p < 0.001) and ST2 (OR = 1.061 (1.040-1.083), p < 0.001) serum concentrations, donor age (OR = 1.046 (1.009-1.085), p = 0.015), left ventricular diastolic dimension (LVDD) (OR = 1.081 (1.016-1.149), p = 0.013), and time from HT to blood collection (OR = 1.256 (1.151-1.371), p < 0.001) were independent risk factors for CAV. The area under the receiver operating characteristics curve (AUC) indicated good prognostic power of IL-33 and ST2 concentrations (AUC = 0.779 and AUC = 0.784, respectively) and excellent prognostic power of the IL-33/ST2 score (AUC = 0.863). Conclusions: Lower IL-33 and higher ST2 serum concentrations, as well as older donor age, larger LVDD and longer time from HT to blood collection, are independently associated with CAV. IL-33 and ST2 have good discriminatory power and the IL-33/ST2 score has excellent strength for detecting CAV.

Serum uric acid is an independent risk factor of worse mid- and long-term outcomes in patients with non-ST-segment elevation acute coronary syndromes.

BACKGROUND: The data on the association between serum uric acid (sUA) concentration and outcomes in patients with an ACS are inconsistent and do not focus on patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). The aim of this study was to analyze an association of sUA concentration on admission and outcomes in those patients. METHODS: Data from the prospective, single-center registry of patients hospitalized due to NSTE-ACS from January 2006 to December 2016 were analyzed retrospectively. The population was divided into quartiles according to the baseline sUA. The primary outcome was the incidence of all-cause death, non-fatal myocardial infarction, stroke and ACS-driven revascularization at 36 months. RESULTS: Total of 2,824 patients with sUA measured on admission were included in this analysis with a median sUA of 352 µmol/L (5.92 mg/dL). Patients with higher sUA were older and more burdened with cardiovascular risk factors and history of coronary events. The prevalence of multivessel coronary artery disease and left main stenosis was significantly higher in patients with higher sUA. Elevated sUA concentration was associated with significantly worse short-, mid- and long-term outcomes. All-cause mortality was significantly higher in each analyzed period. In the multivariable analysis, sUA elevation was identified as an independent predictor of all-cause mortality at 12-month and 36-month follow-up. CONCLUSIONS: Elevated baseline sUA concentration was independently associated with worse mid- and long-term outcomes in patients with NSTE-ACS. Baseline sUA concentration could identify patients with NSTE-ACS at higher risk of more dismal prognosis.

Mechanical circulatory support. An expert opinion of the Association of Intensive Cardiac Care and the Association of Cardiovascular Interventions of the Polish Cardiac Society.

Mechanical circulatory support (MCS) methods are used in patients with both acute and chronic heart failure, who have exhausted other options for pharmacological or surgical treatments. The purpose of their use is to support, partially or completely, the failed ventricles and ensure adequate organ perfusion, which allows patients to restore full cardiovascular capacity, prolonging their life and effectively improving its quality. The three most popular devices include an intra-aortic balloon pump (IABP), percutaneous assist devices (including Impella, TandemHeart), and venoarterial extracorporeal membrane oxygenation (VA-ECMO). A multidisciplinary approach with the special participation of the Heart Team is required to determine the proper MCS strategy, the choice of the supporting method, and the time of its use. The studies published so far do not allow us to determine which MCS method is the safest and the most effective. Thus, the site experience and accessibility of the method seem to matter most today. MCS finds particular application in patients with acute coronary syndromes complicated by refractory cardiogenic shock, as well as in patients with acute heart failure of the high potential for reversibility. It can also serve as a backup for percutaneous coronary interventions of high risk (complex and high-risk indicated percutaneous coronary intervention [PCI], complex and high-risk indicated PCI [CHIP]). The use of appropriate supportive drugs, precise hemodynamic and echocardiographic monitoring, as well as optimal non-invasive or mechanical ventilation, are extremely important in the management of a patient with MCS. The most serious complications of MCS include bleeding, thromboembolic events, as well as infections, and hemolysis.

Sex-related differences and rotational atherectomy: Analysis of 5 177 percutaneous coronary interventions based on a large national registry from 2014 to 2020.

BACKGROUND: Patients undergoing percutaneous coronary interventions (PCI) with rotational atherectomy (RA) have massively calcified coronary arteries and their prognosis differs between sexes. AIMS: The aim of the study was to evaluate the trends in the percentage of sexes in the subsequent years, to compare demographic characteristics between men and women, and to identify factors associated with the risk of periprocedural complications and death. METHODS: We analyzed data on 751 113 patients treated with PCI between 2014 and 2020 from the Polish National Registry of Percutaneous Coronary Interventions (ORPKI). We extracted data on 5 177 (0.7%) patients treated with RA of whom 3 552 (68.6%) were men. To determine risk factors of periprocedural complications and death, a multivariable analysis was performed. RESULTS: The proportion of PCIs involving RA increased between 2014 and 2020 (P <0.001). Almost twice as many RA procedures were performed on men (68.55%), and that proportion did not change in the following years. The female patients were older (75.2 [8.3] vs. 70.5 [9.2] years; P <0.001). When considering periprocedural complications, their overall rate (3.45% vs. 2.31%; P = 0.01) and death rate (0.68% vs. 0.17%; P = 0.006) were greater among women. Also, via multivariable analysis, female sex was found to be a risk factor for greater periprocedural mortality (P = 0.02) and overall complication rate (P = 0.007). CONCLUSIONS: The majority of patients treated with RA are men and sex-related distribution was stable during the analyzed period. Female sex is a risk factor for greater periprocedural complications and mortality in patients treated with RA.
