Impact of chronic total occlusion on prognosis in cardiogenic shock due to unprotected left main coronary artery culprit lesion. Insights from the Polish Registry of Acute Coronary Syndromes.

BACKGROUND: Notwithstanding readily available revascularization, significant advancements in mechanical circulatory support, and pharmacological progress, cardiogenic shock (CS) secondary to unprotected left main culprit lesion-related acute myocardial infarction (ULMCL-related AMI) is associated with very high mortality. In this population, chronic total occlusion (CTO) is relatively frequent. AIMS: This study sought to assess the association between the presence of CTO and 12-month mortality in patients with CS due to ULMCL-related AMI. RESULTS: The study included consecutive patients admitted for AMI-related CS with ULMCL who underwent percutaneous coronary intervention (PCI) and were enrolled in the prospective Polish Registry of Acute Coronary Syndromes (PL-ACS) between January 2017 and December 2021. The patients were stratified into two groups based on the presence of at least one CTO. The primary endpoint was all-cause death at 12 months. Of the 250 included patients, 60 (24%) patients had one or more CTOs of a major coronary artery (+CTO), and in 190 (76%) patients, the presence of CTO was not observed (-CTO). The 12-month mortality rates for the +CTO and -CTO patients were 85% and 69.8%, respectively (P log-rank = 0.03). After multivariable adjustment for differences in the baseline characteristics, the presence of CTO remained significantly associated with higher 12-month mortality (hazard ratio, 1.423; 95% CI, 1.027-1.973; P = 0.034). CONCLUSIONS: Our analysis showed that in patients with CS due to ULMCL-related AMI treated with PCI, the presence of CTO is associated with worse 12-month prognosis.

Impacto pronóstico a diez años del fallo del vaso diana tras un IAMCEST. Perspectivas del ensayo EXAMINATION-EXTEND / Ten-year prognostic impact of target versus non-target vessel failure after STEMI. Insight from the EXAMINATION-EXTEND trial

Introducción y objetivos Se desconoce el impacto pronóstico de los diferentes tipos de eventos adversos tras el infarto agudo de miocardio con elevación del segmento ST (IAMCEST). El objetivo de este trabajo es evaluar los predictores a largo plazo del objetivo combinado orientado al paciente (POCE) y si tener un fallo del vaso diana (FVD) como primer evento puede influir en los resultados. Métodos El ensayo EXAMINATION-EXTEND aleatorizó a pacientes con IAMCEST a tratamiento con stents liberadores de everolimus o a stents convencionales, con un seguimiento de hasta 10 años. En la población del estudio, se evaluaron los predictores de POCE (combinado de mortalidad por cualquier causa, infarto de miocardio y cualquier revascularización). Se clasificó a los pacientes según el tipo de primer evento (FVD primero o FDV no primero) y comparado en términos de POCE posterior. El FVD se definió como el compuesto de muerte cardiaca, IAMCEST del vaso diana y revascularización del vaso diana. Resultados De los 1.498 pacientes del estudio, 529 (35,3%) tuvieron POCE durante el seguimiento a los 10 años. Los predictores independientes de POCE fueron la edad, la diabetes mellitus, el infarto de miocardio previo, la enfermedad arterial periférica y la enfermedad coronaria multivaso. El primer evento fue un FVD o no FVD en 296 y 233 casos respectivamente. No hubo diferencias estadísticamente significativas entre quienes tuvieron primero un FVD y los que tuvieron un evento no FVD en cuanto a POCE (el 21,7 frente al 39,3%; razón de tiempo, 1,79; IC95%, 0,87-3,67; p=0,12) o sus componentes individuales. Conclusiones En el seguimiento a 10 años, alrededor de un tercio de los pacientes con IAMCEST tuvo al menos 1 evento de POCE, cuyos predictores independientes fueron la edad, la diabetes mellitus y una mayor extensión de la enfermedad ateroesclerótica...

Introduction and objectivesAfter ST-segment myocardial infarction (STEMI), the impact of different adverse events on prognosis remains unknown. We aimed to assess very long-term predictors of patient-oriented composite endpoints (POCE) and investigate whether the occurrence of target vessel failure (TVF) vs a non-TVF event as the first event could potentially influence subsequent outcomes. Methods The EXAMINATION.EXTEND trial randomized STEMI patients to receive either an everolimus-eluting stent or a bare-metal stent. The follow-up period was 10 years. Predictors of POCE (a composite of all-cause death, any myocardial infarction, or any revascularization) were evaluated in the overall study population. The patients were stratified based on the type of first event (TVF-first vs non–TVF-first) and were compared in terms of subsequent POCE. TVF was defined as a composite of cardiac death, TV myocardial infarction, or TV revascularization. Results Out of the 1498 enrolled patients, 529 (35.3%) experienced a POCE during the 10-year follow-up. Independent predictors of POCE were age, diabetes mellitus, previous myocardial infarction, peripheral arterial disease, and multivessel coronary disease. The first event was a TVF in 296 patients and was a non-TVF in 233 patients. No significant differences were observed between TVF-first and non–TVF-first patients in terms of subsequent POCE (21.7% vs 39.3%, time ratio 1.79; 95%CI, 0.87-3.67; P=.12) or its individual components. Conclusions At the 10-year follow-up, approximately one-third of STEMI patients had experienced at least 1 POCE. Independent predictors of these events were age, diabetes, and more extensive atherosclerotic disease. The occurrence of a TVF or a non-TVF as the first event did not seem to influence subsequent outcomes. Trial registration number: NCT04462315. (AU)

The characteristic of acute coronary syndromes of patients with multivessel coronary artery disease in centers with and without cardiac surgery on-site.

BACKGROUND: Multivessel disease (MVD) is diagnosed in a fair number of patients with acute coronary syndrome (ACS). There are 36 cardiac-surgery (CS) centres and 157 catheterization laboratories dedicated to treat ACS in Poland. The aim of the study was to analyze MVD patient outcomes presented with ACS in centers with or without CS on-site. METHODS: The present study is a retrospective analysis (2017-2020) of MVD ACS patients (n = 4618) outcomes between those treated in centers with CS on site (n = 595) and those without CS (n = 4023). RESULTS: Patients in CS centers had a higher prevalence of renal failure (13.3% vs. 8.8%, p ≤ 0.001) and a more frequent history of coronary angioplasty - percutaneous coronary intervention (18.9% vs. 14.4%, p = 0.005). During the coronary angiography a femoral artery access was more often used in CS center patients (47.1% vs. 15.2%, p < 0.001). Percutaneous coronary intervention of MVD was more often performed in CS centers (74.6% vs. 71.0%, p = 0.054). In-hospital death (7.6% vs. 4.6%, p = 0.002), reinfarction (1.1% vs. 0.1%, p < 0.001), hemorrhagic complications (6.4% vs. 1.6%, p < 0.001), recurrent target vessel revascularization (1.8% vs. 0.4%, p ≤ 0.001) and pulmonary edema (3.7% vs. 1.5%, p < 0.001) occurred more often in CS centers. CONCLUSIONS: The safety of ACS treatment in MVD patients in centers without CS on site is non-inferior to their treatment in centers with CS on site. Interestingly, there were more in-hospital adverse events observed in ACS MVD patients treated in centers with CS.

Ten-year prognostic impact of target versus non-target vessel failure after STEMI. Insight from the EXAMINATION-EXTEND trial.

Cognitive functions and sense of coherence in patients with carotid artery stenosis-Preliminary report.

Background: There is scarcely any data in the available literature on the relationship between sense of coherence (SOC) and cognitive functioning, and no information on the relationship between SOC and cognitive parameters in patients with carotid atherosclerosis. Aim: The aim of this paper was to determine the relationship of SOC measured prior to carotid artery stenting (CAS) with neurocognitive functioning in patients with carotid atherosclerosis 12 months after CAS. Methods: A total of 35 patients with carotid atherosclerosis completed the SOC-29 Orientation to Life Questionnaire (SOC-29) and completed a cognitive test battery twice, i.e., before (baseline-T1) and 12 months after stent implantation (follow-up-T2). Selected cognitive functions such as memory, attention, perception, visuospatial and executive functions and non-verbal fluency were assessed. Results: One year after the procedure, patients with a higher SOC and sense of manageability present better performance in visual memory. Higher SOC and sense of meaningfulness are positively related to the speed of understanding the changing rules of card sorting (WCST). Conclusion: Higher overall SOC and a component of sense of meaningfulness and manageability may be related to better cognitive functioning 1 year after the procedure.

Immediate versus staged complete revascularization in acute coronary syndrome: A meta-analysis of randomized controlled trials.

BACKGROUND: Clinical guidelines recommend a complete revascularization (CR) in patients with acute coronary syndromes (ACS) and multivessel disease (MVD). However, its optimal timing is unclear. The aim of this meta-analysis was to compare the clinical outcomes following immediate versus staged CR in ACS. METHODS: PubMed and Scopus were searched until March 2023 for randomized controlled trials (RCTs) comparing immediate versus staged CR. The primary endpoint was major adverse cardiovascular event (MACE) at the longest follow-up. Secondary outcomes were all-cause death, cardiovascular death, myocardial infarction (MI), any unplanned revascularization, target-vessel revascularization (TVR), and stent thrombosis. Safety outcomes were major bleeding, contrast volume, procedure duration, and length of hospitalization. RESULTS: Eight RCTs were included (3559 patients, weighted mean follow-up 12.5 months). There were no differences in the primary endpoint (OR 0.74, 95%CI: 0.54-1.01) and in the secondary endpoints of death, and stent thrombosis between the two CR strategies. Immediate CR was associated with a lower risk of recurrent MI (OR 0.51, 95% CI 0.34-0.76), any unplanned revascularization (OR 0.59, 95%CI: 0.43-0.80), and TVR (OR 0.61, 95% CI 0.45-0.84) compared to staged CR. Immediate CR was also associated with lower total contrast volume and shorter total procedure duration and hospitalization length compared to staged CR without differences in major bleedings. CONCLUSION: No difference was found between immediate and staged CR regarding MACE, or deaths rates at one year. Immediate CR may be associated with a lower risk of recurrent MI and unplanned coronary revascularization than staged CR.

Clinical outcomes following different stenting techniques for coronary bifurcation lesions: a systematic review and network meta-analysis of randomised controlled trials.

BACKGROUND: Controversy still exists regarding the optimal treatment of coronary bifurcation lesions. AIMS: We aimed to analyse the evidence from randomised controlled trials (RCTs) to compare outcomes following different bifurcation stenting techniques. METHODS: We systematically searched for RCTs comparing different techniques published up to July 2022. We then conducted a pairwise meta-analysis to compare outcomes between provisional stenting (PS) versus upfront 2-stent techniques. Moreover, we performed a network meta-analysis (NMA) to compare all strategies with each other. The primary endpoint was major adverse cardiac events (MACE). RESULTS: Twenty-four RCTs (6,890 patients) analysed PS, T-stenting, double-kissing (DK)-crush, crush, or culotte stenting. The pairwise meta-analysis did not reveal a significant difference between the PS and 2-stent techniques. However, the prespecified sensitivity analysis, which included RCTs exclusively enrolling patients with true bifurcation lesions, showed a lower rate of MACE following 2-stent techniques, and meta-regression indicated that a longer side branch lesion was associated with a greater benefit from the 2-stent strategy, which was the most apparent in RCTs with a mean lesion length >11 mm. NMA revealed that DK-crush was associated with the lowest MACE rate (odds ratio 0.47, 95% confidence interval: 0.36-0.62; p<0.01; PS as a reference). CONCLUSIONS: Overall, 2-stent techniques were not significantly better than PS in terms of clinical outcomes. However, the results of the sensitivity analysis suggested that there might be a benefit of a 2-stent approach in selected patients with true bifurcation lesions, especially in the case of long side branch lesions. An NMA revealed that DK-crush was associated with the lowest event rates when compared with other techniques.

Prognosis of patients with renal failure one year following non-ST-segment elevation myocardial infarction treated with percutaneous coronary intervention.

OBJECTIVE: Kidney failure is highly prevalent in patients with non-ST-elevation myocardial infarction (NSTEMI). The aim of the study was to evaluate the prognostic significance of baseline renal function regarding in-hospital and 1-year mortality among patients with NSTEMI and treated with percutaneous coronary intervention (PCI). METHODS: Data were obtained from the Polish Registry of Acute Coronary Syndromes (PL-ACS) and included 47,052 NSTEMI patients treated with PCI between 2017 and 2021. The cumulative incidence of all-cause mortality during the 1-year follow-up was presented using the Kaplan-Meier curves. The multivariable Cox regression model was created to adjust the relationship between eGFR (as a spline term) and all-cause mortality for potential confounders. RESULTS: After considering the exclusion criteria, 20,834 cases were evaluated, with a median eGFR of 72.7 (IQR 56.6-87.5) mL/min/1.73 m2. The median age was 69 (62-76) years. The study comprised 4,505 patients with normal (90-120), 10,189 with mild (60-89), 5,539 with moderate (30-59), and 601 with severe eGFR impairment (15-29). Lower eGFR was associated with worse baseline clinical profile and longer in-hospital delay to coronary angiography. There was a stepwise increase in the crude all-cause death rates across the groups at 1 year. The Cox regression model with a spline term revealed that the relationship between eGFR and the risk of death at 1 year was non-linear (reverse J-shaped), and the risk was the lowest in patients with eGFR∼90 mL/min/1.73 m2. CONCLUSIONS: There is a J-curve relationship between the eGFR value and 1-year all-cause mortality in patients with NSTEMI and treated with PCI.

Relationship between stent length and very long-term target lesion failure following percutaneous coronary intervention for ST-elevation myocardial infarction in the drug-eluting stents era: insights from the EXAMINATION-EXTEND study.

BACKGROUND: Little data exist on the relationship between total stent length (TSL) and cardiovascular outcomes at very-long follow-up in patients with ST-elevation myocardial infarction (STEMI) in the 2nd generation drug-eluting stents (DES) era. AIM: To analyze the relationship between TSL and 10-year target-lesion failure (TLF) in STEMI patients treated with percutaneous coronary intervention enrolled in the EXAMINATION-EXTEND. METHODS: The EXAMINATION-EXTEND was an extended-follow-up study of the EXAMINATION trial, which randomized 1:1 STEMI patients to receive DES or bare metal stent (BMS). The primary endpoint was TLF, defined as a composite of target lesion revascularization (TLR), target vessel myocardial infarction (TVMI), or definite/probable stent thrombosis (ST). Relationship between stent length and TLF was evaluated in the whole study group in a multiple-adjusted Cox regression model with TSL as a quantitative variable. Subgroup analysis was also performed according to stent type, diameter, and overlap. RESULTS: A total of 1,489 patients with a median TSL of 23 mm (Q1-Q318-35 mm) were included. TSL was associated with TLF at 10 years (adjusted HR per 5 mm increase of 1.07; 95% CI, 1.01-1.14; P = .02). This effect was mainly driven by TLR and was consistent regardless of stent type, diameter, or overlap. There was no significant relationship between TSL and TV-MI or ST. CONCLUSIONS: In STEMI patients, there is a direct relationship between TSL implanted in the culprit vessel and the risk of TLF at 10 years, mainly driven by TLR. The use of DES did not modify this association.

Stepwise relationship between delay in percutaneous coronary intervention and long-term mortality in patients with non-ST-segment elevation myocardial infarction.

BACKGROUND: Current guidelines recommend coronary catheterization in patients with non-ST- -segment elevation myocardial infarction (NSTEMI) within 24 hours of hospital admission. However, whether there is a stepwise relationship between the time to percutaneous coronary intervention (PCI) and long-term mortality in patients with NSTEMI treated invasively within 24 hours of admission has not been established yet. AIMS: The study aimed to evaluate the association between door-to-PCI time and all-cause mortality at 12 and 36 months in NSTEMI patients presenting directly to a PCI-capable center who underwent PCI within the first 24 hours of hospitalization. METHODS: We analyzed data of patients hospitalized for NSTEMI between 2007-2019, included in the nationwide registry of acute coronary syndromes. Patients were stratified into twelve groups based on 2-hour intervals of door-to-PCI time. The mortality rates of patients within those groups were adjusted for 33 confounding variables by the propensity score weighting method using overlap weights. RESULTS: A total of 37 589 patients were included in the study. The median age of included patients was 66.7 (interquartile range [IQR], 59.0-75.8) years; 66.7% were male, and the median GRACE (Global Registry of Acute Coronary Events) score was 115 (98-133). There were increased 12-month and 36-month mortality rates in consecutive groups of patients stratified by 2-hour door-to-PCI time intervals. After adjustment for patient characteristics, there was a significant positive correlation between the time to PCI and the mortality rates (rs = 0.61; P = 0.04 and rs = 0.65; P = 0.02 for 12-month and 36-month mortality, respectively). CONCLUSIONS: The longer the door-to-PCI time, the higher were 12-month and 36-month all-cause mortality rates in NSTEMI patients.

Dyslipidemia treatment and attainment of LDL-cholesterol treatment goals in patients participating in the Managed Care for Acute Myocardial Infarction Survivors program.

BACKGROUND: Patients after acute myocardial infarction (AMI) are at very high cardiovascular (CV) risk. Therefore, appropriate management of dyslipidemia with adequate lipid-lowering therapy is crucial for preventing subsequent CV events in these patients. AIMS: Our analysis aimed to assess the treatment of dyslipidemia and attainment of low-density lipoprotein cholesterol (LDL-C) treatment goals in patients after AMI who participated in the Managed Care for Acute Myocardial Infarction Survivors (MACAMIS) program. METHODS: This study is a retrospective analysis of consecutive patients with AMI who agreed to participate and completed the 12-month MACAMIS program at one of three tertiary referral cardiovascular centers in Poland between October 2017 and January 2021. RESULTS: 1499 patients after AMI were enrolled in the study. High-intensity statin therapy was prescribed for 85.5% of analyzed patients on hospital discharge. Combined therapy with high-intensity statin and ezetimibe increased from 2.1% on hospital discharge to 18.2% after 12 months. In the whole study cohort, 20.4% of patients achieved the LDL-C target of < 55 mg/dl ( < 1.4 mmol/l), and 26.9% of patients achieved at least a 50% reduction in LDL-C level one year after AMI. CONCLUSIONS: Our analysis suggests that participation in the managed care program might be associated with improved quality of dyslipidemia management in AMI patients. Nonetheless, only one-fifth of patients who completed the program achieved the treatment goal for LDL-C. This highlights the constant need for optimizing lipid-lowering therapy to meet treatment targets and reduce CV risk in patients after AMI.

Clinical characteristics and 12-month outcomes of patients with myocardial infarction with nonobstructive coronary arteries before and during the COVID-19 pandemic.

INTRODUCTION: SARS­CoV­2 infection is associated with an increased risk of thromboembolic complications. Thromboembolism is one of the possible causes of myocardial infarction with nonobstructive coronary arteries (MINOCA). OBJECTIVES: We aimed to compare the characteristics and 12­month clinical outcomes of patients with MINOCA treated before and during the COVID­19 pandemic. PATIENTS AND METHODS: We retrospectively analyzed data of 51 734 patients with acute myocardial infarction registered in the nationwide Polish Registry of Acute Coronary Syndromes database in 2019 and 2020. The final study group included 3178 patients with MINOCA. We compared the baseline characteristics, management strategies, and 12­month clinical outcomes of the MINOCA patients treated before (2019) and during the COVID­19 pandemic (2020). RESULTS: The rate of MINOCA was higher in 2019 than in 2020 (6.3% vs 5.9%; P = 0.03). The only difference between the groups was a higher hypercholesterolemia rate before the pandemic (33.9% vs 28.2%; P <0.001). In­hospital stroke was observed more frequently during the pandemic (0% vs 0.3%; P = 0.01), whereas other in­hospital complications were similar between the groups. Most patients were discharged on aspirin (85.6%), a ß­blocker (73.1%), an angiotensin­converting enzyme inhibitor / angiotensin receptor blocker (70.2%), and a statin (62.7%), but only 50.6% of the participants received a P2Y12 inhibitor. There was no difference in 12­month all­cause mortality between the patients with MINOCA treated before and during the pandemic (9.2% vs 11%; P = 0.09). CONCLUSIONS: We observed a lower percentage of MINOCA cases and higher in­hospital stroke rates in the MINOCA patients treated during the COVID­19 pandemic (2020). The possible association between worse clinical outcomes of the MINOCA patients treated during the pandemic and the increased risk for thromboembolic complications of SARS­CoV­2 infection needs further evaluation.

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.

Symptoms of Anxiety and Depression and Sense of Coherence in Patients Undergoing Carotid Artery Stenting.

BACKGROUND: The sense of coherence is lower in patients with somatic diseases and psychiatric disorders. PURPOSE: The purpose of this study was to evaluate the intensity of depression and anxiety symptoms and their relationship with the sense of coherence and to try to determine the relationship between the strength of sense of coherence and symptoms of depression and anxiety with the presence of symptoms of carotid atherosclerosis in a group of patients undergoing carotid artery stenting. METHODS: 35 patients, including 13 with symptomatic atherosclerosis in the carotid arteries, completed self-report tests: Hospital Scale of Depression and Anxiety (HADS) and the SOC-29 Life Orientation Questionnaire (SOC-29), 22 of whom also rated their subjective feelings of anxiety and depression on a scale included in the author's questionnaire. RESULTS: Both symptomatic and asymptomatic patients did not differ significantly in the severity of depression, but they differed in anxiety levels as assessed by the HADS scale. There were no differences in the overall strength of sense of coherence and its individual components. Nearly 12% of those undergoing carotid artery stenting have pronounced anxiety symptoms, and just over 14% have pronounced depression symptoms. A higher overall sense of coherence and its components are associated with lower severity of depression symptoms. Lower severity of anxiety correlates negatively with a higher sense of understanding, meaningfulness, and holistic Sense of Coherence (SOC). Manageability appeared higher in men. CONCLUSIONS: SOC is an important health-promoting factor that is preferably related to mental health parameters of patients with carotid atherosclerosis.

Cognitive Functions after Carotid Artery Stenting-1-Year Follow-Up Study.

BACKGROUND: The revascularization of carotid arteries minimizes the risk of future cerebral stroke and usually improves cognitive functions. The aim of this study was to assess changes in cognitive function and verify the hypothesis assuming an improvement of selected cognitive functions-psychomotor speed, visuospatial episodic memory, executive function and verbal fluency-in patients after carotid artery stenting during a 12-month follow-up. METHODS: 47 persons subject to CAS, including 13 symptomatic persons, were examined before and 12 months after a procedure with a psychological test battery (digit symbol test-DS, Rey-Osterrieth complex figure test-ROCF, Wisconsin Card Sorting Test-WCST, letter verbal fluency-LVF). Sociodemographic data and clinical parameters were acquired from an author questionnaire. RESULTS: The one-year follow-up, after the performed CAS procedure, demonstrated a significant improvement of psychomotor speed, visuospatial episodic memory, and executive function. No changes in the area of verbal fluency or decline in any of cognitive functions under analysis were observed. CONCLUSIONS: Carotid artery stenting improves cognitive functioning, both in the area of basic and more complex cognitive functions in persons with carotid atherosclerosis.

Does the presence of physician-staffed emergency medical services improve the prognosis in out-of-hospital cardiac arrest? A propensity score matching analysis.

BACKGROUND: Substantial differences in survival after out-of-hospital cardiac arrest (OHCA) have been observed between countries. These might be attributed to the organization of emergency medical service (EMS) systems, including prehospital physician involvement. However, limited data exist on the physician's role in improving survival after OHCA. AIMS: To compare prehospital and in-hospital outcomes of OHCA patients attended by physician-staffed EMS vs. paramedic-staffed EMS units. METHODS: Among all patients enrolled in the regional, prospective registry of OHCA in southern Poland, we excluded those aged <18 years, with unwitnessed or EMS-witnessed cardiac arrest, without attempted cardiopulmonary resuscitation (CPR), attended by more than one EMS, or with traumatic cardiac arrest. The groups were matched 1:1 using propensity scores for baseline characteristic variables that might influence physician-staffed EMS dispatch. RESULTS: A total of 812 OHCA cases were included in the current analysis. Among them, 351 patients were attended by physician-staffed EMS. There were no differences in baseline characteristics in the propensity-score matched cohort consisting of 351 pairs. The return of spontaneous circulation (ROSC) was more often achieved in the physician-staffed EMS group (42.7% vs. 33.3%; P = 0.01). The prehospital survival rate was also higher in this group (34.1% vs. 19.2%; P <0.01). However, there were no significant differences in survival rate to discharge between cases treated by physician-staffed and paramedic-staffed EMS (9.7% vs. 7.0%; P = 0.22). CONCLUSIONS: OHCA patients attended by physician-staffed EMS were more likely to have ROSC and survive till hospital admission. However, better prehospital outcomes might not translate into improved in-hospital prognosis in these patients.
