RESUMEN
AIM: To assess the effects of 1- or ≥3-month dual antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients who received biodegradable-polymer sirolimus-eluting stents for complex percutaneous coronary intervention (PCI) and/or acute coronary syndrome (ACS). METHODS AND RESULTS: In the MASTER DAPT trial, 3383 patients underwent non-complex (abbreviated DAPT, n = 1707; standard DAPT, n = 1676) and 1196 complex (abbreviated DAPT, n = 588; standard DAPT, n = 608) PCI. Co-primary outcomes at 335 days were net adverse clinical events [NACE; composite of all-cause death, myocardial infarction, stroke, and bleeding academic research consortium (BARC) 3 or 5 bleeding events]; major adverse cardiac or cerebral events (MACCE; all-cause death, myocardial infarction, and stroke); and Types 2, 3, or 5 BARC bleeding. Net adverse clinical events and MACCE did not differ with abbreviated vs. standard DAPT among patients with complex [hazard ratio (HR): 1.03, 95% confidence interval (CI): 0.69-1.52, and HR: 1.24, 95% CI: 0.79-1.92, respectively] and non-complex PCI (HR: 0.90, 95% CI: 0.71-1.15, and HR: 0.91, 95% CI: 0.69-1.21; Pinteraction = 0.60 and 0.26, respectively). BARC 2, 3, or 5 was reduced with abbreviated DAPT in patients with and without complex PCI (HR: 0.64; 95% CI: 0.42-0.98, and HR: 0.70; 95% CI: 0.55-0.89; Pinteraction = 0.72). Among the 2816 patients with complex PCI and/or ACS, NACE and MACCE did not differ and BARC 2, 3, or 5 was lower with abbreviated DAPT. CONCLUSION: In HBR patients free from recurrent ischaemic events at 1 month, DAPT discontinuation was associated with similar NACE and MACCE and lower bleeding rates compared with standard DAPT, regardless of PCI or patient complexity. CLINICAL TRIAL REGISTRATION: This trial is registered with ClinicalTrials.gov, number NCT03023020, and is closed to new participants, with follow-up completed.

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.

BACKGROUND: The aim of the study was to assess anatomical and procedural predictors of clinical and procedural failure of rotational atherectomy (RA) in an all-comers population.MethodsâandâResults:A total of 534 consecutive patients who underwent RA were included in a double-center observational study. The primary composite endpoint consisted of: rota-wire introduction failure, burr-passage failure, periprocedural complications and procedure-related major adverse events. The second primary endpoint included rota-wire introduction failure and burr-passage failure. The primary endpoint occurred in 76 (14.2%) patients and the second primary endpoint occurred in 64 (12%) Periprocedural complications occurred in 23 (4.3%) and procedure-related adverse events in 23 (4.3%) patients. Multivariable analysis revealed angulation on lesion ≤90° (HR=2.18, 95% CI: 1.21-3.94, P=0.0096) and sequential lesion (HR=1.89, 95% CI: 1.01-3.54, P=0.046) as independent predictors of no clinical success of RA. Multivariable analysis revealed again that angulation on lesion ≤90° (HR=2.26, 95% CI: 1.16-4.40, P=0.02) and sequential lesion (HR=3.77, 95% CI: 1.64-8.69, P<0.01) as independent predictors of no procedural success of RA. CONCLUSIONS: The presence of an acute angulation on lesion and sequential lesion are independent determinants of clinical and procedural failure of RA. Further research is necessary to establish a score predicting RA failure, which can help in preproceduralrisk stratification of patients undergoing complex percutaneous coronary intervention with RA.

OBJECTIVES: To assess long-term safety and efficacy of the Xposition S self-apposing stent in the treatment of unprotected left main coronary artery (ULMCA) disease. BACKGROUND: Percutaneous intervention with stents has emerged as a valid alternative to surgical revascularization to treat ULMCA disease. Conventional balloon-expandable stents face technical challenges, particularly in large left main diameter requiring extensive optimization and side branch access in distal bifurcation. Xposition S allows for optimal apposition, bridging diameter differences, and allows expansion to vessel diameters up to 6.0 mm. METHODS: Between June 2016 and July 2017, 205 patients were enrolled in this international, prospective, multicenter registry. Patients with SYNTAX score ≥ 33 or recent STEMI were excluded. IVUS during procedure was performed in a prespecified subgroup of 50 patients. The primary clinical endpoint was 12 months Target lesion failure (TLF) and the primary efficacy endpoint was angiographic success. RESULTS: Distal left main bifurcation was involved in 92.7%, treated with provisional approach in most cases (79.4%). TLF rate at 12 months was 8.3%, which was defined as a composite of cardiac death (2.0%), target-vessel MI (2.9%), and TLR (5.4%). Most revascularizations occurred at SB ostium. IVUS analysis demonstrated optimal stent apposition with only one reported malapposition and promising poststenting minimal stent area measures. CONCLUSIONS: The TRUNC study confirms that Xposition S self-apposing stent is a valid and feasible option for the treatment of ULMCA disease. Such results were reached without the systematic need of stent optimisation techniques, focusing mainly on lesion treatment.

BACKGROUND: There is a paucity of data on left main (LM) percutaneous coronary intervention (PCI) therapy with dedicated DES platforms. The LM-STENTYS is a multicenter registry aimed at evaluating clinical outcome after PCI of LM performed with a self-apposing Stentys DES implantation. METHODS: The registry consists of 175 consecutive patients treated with Stentys DES implanted to LM. The primary endpoint was the composite of major adverse cardiac and cerebral events (MACCE) defined as cardiac death, myocardial infarction (MI), target lesion revascularization (TLR), and stroke assessed after 1 year. The secondary endpoint was stent thrombosis (ST) at 1 year. RESULTS: The median age was 69 years (IQR, 62-78 years). Acute coronary syndrome (ACS) was the presenting diagnosis in 117 (66.9%) patients [74 (63.2%) unstable angina, 31 (26.5%) NSTEMI, 12 (10.3%) STEMI] and stable angina (SA) was present in 58 (33.1%) patients. The median SYNTAX score was 23.0 (IQR, 18.7-32.2) in the SA group and 25.0 (IQR, 20.0-30.7) in the ACS group. During 1-year follow-up in the SA group two (3.4%) MACCE occurred, both of them were cardiac deaths. In ACS patients there were 19 (16.2%) MACCE [9 (7.7%) cardiac deaths, 11 (9.4%) MIs, 11(9.4%) TLR, 1(0.9%) stroke]. Altogether, three (1.7%) cases of acute ST were noted, all of them in ACS subset. CONCLUSION: LM PCI using self-apposing Stentys DES showed favorable clinical outcomes at 1-year in patients with SA. Events of ST in the ACS group warrant further research.

INTRODUCTION: Transfemoral approach (TFA) may be preferred access site in order to facilitate complex percutaneous procedures such as rotational atherectomy (RA). Notwithstanding, there is a growing evidence that transradial approach (TRA) is associated with lower access site complication rates and even lower mortality. The aim was to assess in-hospital and 1-year outcomes in patients undergoing RA using TRA, in comparison to TFA. METHODS: A single center observational study included all consecutive patients, who underwent RA from 2010 to 2015. Primary endpoints were procedural success, in-hospital mortality and major adverse cardiovascular events (MACE). Secondary endpoints were 1-year all-cause mortality and MACE. RESULTS: The study included 177 patients, 69% in TRA group and 31% in TFA group. Except for male sex and logistic Euroscore II there were no differences in common risk factors. There was no difference in procedural success (95% vs 87%, P = 0.07) with even a trend in favor of TRA. Performing RA via TRA lower amount of contrast volume (P = 0.009) was used and hospital stay after the procedure was shorter (P = 0.004). Periprocedural complication rates were similar, however patients with TFA had significantly higher rate of major access site bleedings (13% vs 1%, P = 0.001), with no differences in mortality and other adverse events both in-hospital and during 1-year observation. CONCLUSIONS: Even though RA is a demanding technique, when performed via TRA allows to maintain the same procedural success and long-term results in comparison to TFA, reduces in-hospital major access site bleedings, lowers the amount of contrast media and shortens hospital stay.

KEY POINTS: In humans, excitation of peripheral chemoreceptors with systemic hypoxia causes hyperventilation, hypertension and tachycardia. However, the contribution of particular chemosensory areas (carotid vs. aortic bodies) to this response is unclear. We showed that selective stimulation of the carotid body by the injection of adenosine into the carotid artery causes a dose-dependent increase in minute ventilation and blood pressure with a concomitant decrease in heart rate in conscious humans. The ventilatory response was abolished and the haemodynamic response was diminished following carotid body ablation. We found that the magnitude of adenosine evoked responses in minute ventilation and blood pressure was analogous to the responses evoked by hypoxia. By contrast, opposing heart rate responses were evoked by adenosine (bradycardia) vs. hypoxia (tachycardia). Intra-carotid adenosine administration may provide a novel method for perioperative assessment of the effectiveness of carotid body ablation, which has been recently proposed as a treatment strategy for sympathetically-mediated diseases. ABSTRACT: Stimulation of peripheral chemoreceptors by acute hypoxia causes an increase in minute ventilation (VI), heart rate (HR) and arterial blood pressure (BP). However, the contribution of particular chemosensory areas, such as carotid (CB) vs. aortic bodies, to this response in humans remains unknown. We performed a blinded, randomized and placebo-controlled study in 11 conscious patients (nine men, two women) undergoing common carotid artery angiography. Doses of adenosine ranging from 4 to 512 µg or placebo solution of a matching volume were administered in randomized order via a diagnostic catheter located in a common carotid artery. Separately, ventilatory and haemodynamic responses to systemic hypoxia were also assessed. Direct excitation of a CB with intra-arterial adenosine increased VI, systolic BP, mean BP and decreased HR. No responses in these variables were seen after injections of placebo. The magnitude of the ventilatory and haemodynamic responses depended on both the dose of adenosine used and on the level of chemosensitivity as determined by the ventilatory response to hypoxia. Percutaneous radiofrequency ablation of the CB abolished the adenosine evoked respiratory response and partially depressed the cardiovascular response in one participant. The results of the present study confirm the excitatory role of purines in CB physiology in humans and suggest that adenosine may be used for selective stimulation and assessment of CB activity. The trial is registered at ClinicalTrials.gov NCT01939912.

Percutaneous treatment of calcified coronary lesions is still a challenge in modern interventional cardiology practice. Coronary angiography is limited to the precise and quantitative assessment of calcium in coronary arteries. Intracoronary imaging (ICI) modalities, including optical coherence tomography (OCT) and intravascular ultrasound (IVUS), produce a very detailed image of calcifications and could help in proper percutaneous treatment. Intracoronary imaging indicates the need to use additional tools and improves the final effect of an intervention. Drawing on the already published literature, the authors focused on the qualification of patients to the procedure, conduct and result of interventional procedures involving calcified lesions supported by ICI. The article shows the advantages and disadvantages of both ICI methods in general and especially in calcified lesions. Currently available tools dedicated to dealing with coronary calcium and helping to meet optimal stent implantation criteria are also described. This article reviews the data on ICI implementation in daily clinical practice to improve the results of percutaneous interventions, and indicates further directions.
RESUMEN
Introduction: Rotational atherectomy (RA) presents superior efficacy over traditional balloon angioplasty in managing calcified plaques, albeit being associated with a perceived heightened aggressiveness and increased risk of periprocedural complications. Aim: To assess the frequency and predictive factors of periprocedural myocardial infarction (MI) following RA. Material and methods: This was a retrospective observational study, encompassing 534 patients. The definition of periprocedural MI was consistent with the 4th universal definition of MI. Results: Periprocedural MI occurred in 45 (8%) patients. This subset tended to be older (74.6 ±8.2 vs. 72 ±9.3%; p = 0.04) with SYNTAX Score (SS) > 33 points (p = 0.01), alongside elevated rates of no/slow flow (p = 0.0003). These patients less often fulfilled the indication for RA, which is a non-dilatable lesion. The incidence of traditional risk factors was similar in both groups. Univariable logistic regression models revealed: male gender (OR = 0.54; p = 0.04), non-dilatable lesion (OR = 0.41; p = 0.01), prior coronary artery bypass grafting (CABG) (OR = 0.07; p = 0.01) as negative and SS > 33 (OR = 2.8; p = 0.02), older age (OR = 1.04; p = 0.04), no/slow flow (OR = 7.85; p = 0.002) as positive predictors. The multivariable model showed that occurrence of no/slow flow (OR = 6.7; p = 0.02), SS > 33 (OR = 2.95; p = 0.02), non-dilatable lesion (OR = 0.42; p = 0.02), and prior CABG (OR = 0.08; p = 0.02) were independent predictors of periprocedural MI. Conclusions: Periprocedural MI after RA was not an uncommon complication, occurring in nearly one-twelfth of patients. Our analysis implicated female gender, older age, and more severe coronary disease in its occurrence. As expected, the presence of no/slow flow amplified the risk of periprocedural MI, whereas prior CABG and non-dilatable lesions mitigated this risk.
RESUMEN
The safety of simultaneous vaccination for Respiratory Syncytial Virus (RSV) and influenza in vulnerable high-risk heart failure (HF) patients remains unclear. In an open-label, prospective study, 105 patients received concurrent influenza (Vaxigrip Tetra, season 2023/2024, Sanofi) and RSV (Arexvy, GSK) vaccinations from September 15th to November 17th, 2023. Adverse events were collected on the fourth-day post-vaccination. Overall, the vaccination was well tolerated, with the most common reaction being injection site pain (63 %). General symptoms occurred in 33 % of patients, predominantly fatigue (23 %), myalgia (12 %), and headache (9 %). Grade 3 reactions were observed in 6 % of patients, and a few experienced temperature elevation or flu-like symptoms, managing them with antipyretics. Notably, there were no exacerbations of HF, hospitalizations, or deaths within a week post-vaccination. This study indicates the safety of simultaneous influenza and RSV vaccination in high-risk HF patients, with a low incidence of mild adverse events.

Background: The rate of in-stent restenosis (ISR) is decreasing; however, it is still a challenge for contemporary invasive cardiologists. Therapeutic methods, including drug-eluting balloons (DEBs), intravascular lithotripsy, excimer laser coronary atherectomy, and imaging-guided percutaneous coronary intervention (PCI) with drug-eluting stents (DES), have been implemented. Patients with diabetes mellitus (DM) are burdened with a higher risk of ISR than the general population. Aims: DM-Dragon is aimed at evaluating the clinical outcomes of ISR treatment with DEBs vs. DES, focusing on patients with co-existing diabetes mellitus. Methods: The DM-Dragon registry is a retrospective study comprising data from nine high-volume PCI centers in Poland. A total of 1117 patients, of whom 473 individuals had DM and were treated with PCI due to ISR, were included. After propensity-score matching (PSM), 198 pairs were created for further analysis. The primary outcome of the study was target lesion revascularization (TLR). Results: In DM patients after PSM, TLR occurred in 21 (10.61%) vs. 20 (10.1%) in non-diabetic patients, p = 0.8690. Rates of target vessel revascularization (TVR), target vessel myocardial infarction, device-oriented composite endpoint (DOCE), and cardiac death did not differ significantly. Among diabetic patients, the risk of all-cause mortality was significantly lower in the DEB group (2.78% vs. 11.11%, HR 3.67 (95% confidence interval, CI) [1.01-13.3), p = 0.0483). Conclusions: PCI with DEBs is almost as effective as DES implantation in DM patients treated for ISR. In DM-Dragon, the rate of all-cause death was significantly lower in patients treated with DEBs. Further large-scale, randomized clinical trials would be needed to support these findings.
RESUMEN
BACKGROUND: Evidence suggests that drug-coated balloons may benefit in-stent restenosis (ISR) treatment. However, the efficacy of new-generation sirolimus-coated balloon (SCB) compared with the latest generation drug-eluting stents (DESs) has not been studied in this setting. METHODS: All patients in the EASTBORNE (The All-Comers Sirolimus-Coated Balloon European Registry) and DEB-DRAGON (DEB vs Thin-DES in DES-ISR: Long Term Outcomes) registries undergoing percutaneous coronary intervention for DES-ISR were included in the study. The primary study end point was target lesion revascularization at 24 months. Secondary end points were major adverse cardiovascular events, all-cause death, myocardial infarction, and target vessel revascularization at 24 months. Our goal was to evaluate the efficacy and safety of SCB versus thin-struts DES in ISR at long-term follow-up. RESULTS: A total of 1545 patients with 1679 ISR lesions were included in the pooled analysis, of whom 621 (40.2%) patients with 621 lesions were treated with thin-strut DES and 924 (59.8%) patients with 1045 lesions were treated with SCB. The unmatched cohort showed no differences in the incidence of target lesion revascularization (10.8% versus 11.8%; P=0.568); however, there was a trend toward lower rates of myocardial infarction (7.4% versus 5.0%; P=0.062) and major adverse cardiovascular events (20.8% versus 17.1%; P=0.072) in the SCB group. After propensity score matching (n=335 patients per group), there were no significant differences in the rates of target lesion revascularization (11.6% versus 11.8%; P=0.329), target vessel revascularization (14.0% versus 13.1%; P=0.822), myocardial infarction (7.2% versus 4.5%; P=0.186), all-cause death (5.7% versus 4.2%; P=0.476), and major adverse cardiovascular event (21.5% versus 17.6%; P=0.242) between DES and SCB treatment. CONCLUSIONS: In patients with ISR, angioplasty with SCB compared with thin-struts DES is associated with comparable rates of target lesion revascularization, target vessel revascularization, myocardial infarction, all-cause death, and major adverse cardiovascular events at 2 years.
RESUMEN
AIM: The RESHAPE-HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE-HF2 trial compared to those enrolled in the COAPT and MITRA-FR trials. METHODS AND RESULTS: The RESHAPE-HF2 study is an investigator-initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate-to-severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8-9.0) and median plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 2745 (1407-5385) pg/ml. Most patients were prescribed beta-blockers (96%), diuretics (96%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium-glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end-diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm2, respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA-FR, those enrolled in RESHAPE-HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT-proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. CONCLUSION: Patients enrolled in RESHAPE-HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate-to-severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA-FR trials. The results of RESHAPE-HF2 will provide crucial insights regarding broader application of the transcatheter edge-to-edge repair procedure in clinical practice.

Coronary computed tomography angiography (CTA) is a widely accepted, non-invasive diagnostic modality for the evaluation of patients with suspected coronary artery disease (CAD). However, a limitation of CTA is its inability to provide information on the hemodynamic significance of the coronary lesion. The recently developed stress dynamic CT perfusion technique has emerged as a potential solution to this diagnostic challenge. Dynamic CT myocardial perfusion provides information on the hemodynamic consequences of coronary stenosis and is used to detect myocardial ischemia. The combination of stress dynamic CT myocardial perfusion with CTA provides a comprehensive assessment that integrates anatomical and functional information. CT myocardial perfusion has been validated in several clinical studies and has shown comparable accuracy to Positron Emission Tomography (PET) and stress magnetic resonance imaging (MRI) in the diagnosis of hemodynamically significant coronary stenosis and superior performance to Single Photon Emission Computed Tomography (SPECT). More importantly, CTP-derived myocardial perfusion has been shown to have a strong correlation with FFR, and the use of CTP results in a reduction of negative catheterizations. In the context of suspected stable coronary artery disease, the CT protocol with dynamic perfusion imaging combined with CTA eliminates the need for additional testing, making it a convenient "one-stop-shop" method and an effective gatekeeper to an invasive approach.
RESUMEN
Introduction: The most common side effect of ticagrelor is dyspnea, which leads to premature withdrawal of this life-saving medication in 6.5% of patients. Increased chemoreceptors' sensitivity was suggested as a possible pathophysiological explanation of this phenomenon; however, the link between oversensitization of peripheral and/or central chemosensory areas and ticagrelor intake has not been conclusively proved. Methods: We measured peripheral chemoreceptors' sensitivity using hypoxic ventilatory response (HVR), central chemoreceptors' sensitivity using hypercapnic hyperoxic ventilatory response (HCVR), and dyspnea severity before and 4 ± 1 weeks following ticagrelor initiation in 11 subjects with chronic coronary syndrome undergoing percutaneous coronary intervention (PCI). The same tests were performed in 11 age-, sex-, and BMI-matched patients treated with clopidogrel. The study is registered at ClinicalTrials.com at NCT05080478. Results: Ticagrelor significantly increased both HVR (0.52 ± 0.46 vs. 0.84 ± 0.69 L min-1 %-1; p < 0.01) and HCVR (1.05 ± 0.64 vs. 1.75 ± 1.04 L min-1 mmHg-1; p < 0.01). The absolute change in HVR correlated with the change in HCVR. Clopidogrel administration did not significantly influence HVR (0.63 ± 0.32 vs. 0.58 ± 0.33 L min-1%-1; p = 0.53) and HCVR (1.22 ± 0.67 vs. 1.2 ± 0.64 L min-1 mmHg-1; p = 0.79). Drug-related dyspnea was reported by three subjects in the ticagrelor group and by none in the clopidogrel group. These patients were characterized by either high baseline HVR and HCVR or excessive increase in HVR following ticagrelor initiation. Discussion: Ticagrelor, contrary to clopidogrel, sensitizes both peripheral and central facets of chemodetection. Two potential mechanisms of ticagrelor-induced dyspnea have been identified: 1) high baseline HVR and HCVR or 2) excessive increase in HVR or HVR and HCVR. Whether other patterns of changes in chemosensitivities play a role in the pathogenesis of this phenomenon needs to be further investigated.
RESUMEN
BACKGROUND: Cardiovascular safety of marathon running middle-aged amateurs remains unclear. We previously hypothesized that transient release of cardiac troponin I (cTnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), in addition to an acute inflammatory response to exercise, may be the cause. OBJECTIVES: To evaluate the effects of running a marathon on inflammatory biomarkers, and its impact on cardiovascular function. MATERIAL AND METHODS: Thirty-three healthy male amateur runners aged ≥50 (mean age: 57 ±7 years) were enrolled in the study. Venous blood samples were obtained before the marathon, just after the race, and 2-4 days and 7 days after the marathon. Using novel single molecule counting (SMC) technology, we measured plasma concentrations of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α). White blood cell (WBC) count was measured using a certified hematology analyzer. The results were related to previous analyses on cardiovascular stress and endothelial function biomarkers. Transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) were used to determine myocardial function. RESULTS: We observed a sharp rise of all studied biomarkers after the race, which subsequently normalized after 2-4 days and stayed within the normal range 7 days after the race. We found no correlation between inflammatory and cardiovascular stress biomarkers. Transthoracic echocardiography and CMR did not show ischemic or inflammatory myocardial damage. CONCLUSIONS: Marathon running is associated with a sharp and significant rise in inflammatory and cardiovascular stress biomarkers. We found no connection between immune activation and cardiac biomarker release. Cardiovascular imaging showed no myocardial damage due to ischemia or inflammation.

Data regarding rotational atherectomy percutaneous coronary intervention (RA PCI) angioplasty in the left main (LM) coronary artery are scarce, and mostly outdated. We aimed to describe clinical outcomes of RA PCI in LM. Patients requiring RA in 8 European countries and 19 centers were prospectively and consecutively included in the European registry of Cardiac Care of Calcified and Complex patients registry. In-hospital data collection and 1-year follow-up were performed for each patient. Between October 2016 and July 2018, 966 patients with complete data were included. Among them, 241 presented with an LM lesion, and 171 required an LM lesion preparation by RA. The latter, allocated to the LM-RA group, were compared with the 725 patients in the non-LM-RA group. Clinical success of the RA procedure was comparable in both groups, but in-hospital major adverse cardiac events were higher in the RA-LM group (7.6% vs 3.2%, adjusted p = 0.04), mainly driven by a higher in-hospital mortality rate (5.3 vs 0.3%, adjusted p = 0.005). At 1-year follow-up, mortality and major adverse cardiac event rates were comparable in both groups (12.9% vs 8.0%, adjusted p value: 0.821, and 15.8% vs 10.9%, adjusted p value: 0.329, respectively), but the rate of target vessel revascularization remained higher in the RA-LM group (5.3% vs 3.2%, adjusted p = 0.021). In conclusion, RA PCI is an efficient option for calcified LM lesions, providing acceptable outcomes regarding this population with high risk at 1 year, and yields comparable outcomes with RA PCI performed on non-LM lesions.

BACKGROUND: It was hypothesized that the time-appropriate return to a resting heart rate (HR) after cessation of exercise could be a marker for predicting outcomes in patients with heart failure (HF). We aimed to evaluate the prognostic value of HR recovery in functional improvement among adults with severe aortic stenosis undergoing percutaneous aortic valve implantation (TAVI). METHODS: We performed a 6 min walk test (6MWT) in 93 individuals before TAVI and 3 months after the procedure. The change in walking distance was calculated. During the pre-TAVI 6MWT, we analyzed the differences between baseline HR, HR at the end of the test, and HR at the 1st, 2nd, and 3rd minute of recovery. RESULTS: After 3 months, 6MWT distances improved by 39 ± 63 m and reached a total of 322 ± 117 m. Multiple linear regression proved the differences between HR after 2 min of recovery and baseline HR in pre-TAVI after a 6MWT was the only significant predictor of waking distance improvement during follow-up. CONCLUSIONS: Our study suggests that analysis of HR recovery after a 6MWT may be a helpful and easy parameter to assess improvements in exercise capacity after TAVI. This simple method can help to identify patients in whom no significant benefit in functional improvement can be expected despite successful valve implantation.

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.

Frailty syndrome (FS) is one of the most important variables that have a proven impact on the increased risk of morbidity and mortality in cardiac surgery. However, FS assessment is not routinely incorporated into daily clinical practice or included in commonly used risk assessment models. The inclusion of FS in perioperative risk prediction models in cardiac surgery would not only allow for a more accurate assessment but could also assist in the selection of an appropriate treatment strategy while favoring the appropriate use of clinical resources. The identification of FS in the qualification process must not be seen as an absolute contraindication to cardiac surgery but as an opportunity to adequately prepare the patient for the procedure. However, the literature is heterogeneous in terms of the selection of an appropriate tool for identifying FS. Selected tools commonly used in the assessment of FS in patients with cardiovascular disease, including those of greatest relevance in cardiac surgery, are presented in this editorial.
