RESUMEN
BACKGROUND: Data on radial access (RA) as an independent risk factor for acute kidney injury (AKI) in myocardial infarction (MI) patients are conflicting. Our aim was to assess how RA influences the incidence of AKI in MI patients undergoing percutaneous coronary intervention (PCI). METHODS: Data from 3842 MI patients undergoing PCI at our institution from January 2011 to December 2016, of which 35.8% were performed radially, were retrospectively analyzed. A propensity-matched analysis was performed to adjust for differences in the baseline characteristics between the RA and femoral access (FA) groups. The effect of RA on the incidence of AKI was observed. RESULTS: In the unmatched cohort, AKI occurred less often in the RA group [77 (5.6%) patients in the RA group compared to 250 (10.1%) patients in the FA group; p = 0.001]. After propensity-matched adjustment, the incidence of AKI was similar in the two groups. After adjustment for potential confounders, RA was not identified as an independent predictive factor for AKI in either the unmatched or the propensity-matched cohort. Bleeding, heart failure, age ≥ 70 years, renal dysfunction, and the contrast volume/GFR ratio predicted AKI in both cohorts. Additionally, diabetes, contrast volume, and hypertension were predictive of AKI in the unmatched cohort. CONCLUSION: The access site was not independently associated with the incidence of AKI in patients with MI in both a non-matched and a propensity-matched cohort. Our study result suggests that the lower incidence of AKI in patients treated with RA in an unmatched cohort might be substantially influenced by confounding factors, especially bleeding.

Atherosclerosis is a major contributor to morbidity and mortality worldwide. With therapeutic consequences in mind, several risk scores are being used to differentiate individuals with low, intermediate or high cardiovascular (CV) event risk. The most appropriate management of intermediate risk individuals is still not known, therefore, novel biomarkers are being sought to help re-stratify them as low or high risk. This narrative review is presented in two parts. Here, in Part 1, we summarise current knowledge on serum (serological) biomarkers of atherosclerosis. Among novel biomarkers, high sensitivity C-reactive protein (hsCRP) has emerged as the most promising in chronic situations, others need further clinical studies. However, it seems that a combination of serum biomarkers offers more to risk stratification than either biomarker alone. In Part 2, we address genetic and imaging markers of atherosclerosis, as well as other developments relevant to risk prediction.

This is Part 2 of a two-part review summarising current knowledge on biomarkers of atherosclerosis. Part 1 addressed serological biomarkers. Here, in part 2 we address genetic and imaging markers, and other developments in predicting risk. Further improvements in risk stratification are expected with the addition of genetic risk scores. In addition to single nucleotide polymorphisms (SNPs), recent advances in epigenetics offer DNA methylation profiles, histone chemical modifications, and micro-RNAs as other promising indicators of atherosclerosis. Imaging biomarkers are better studied and already have a higher degree of clinical applicability in cardiovascular (CV) event prediction and detection of preclinical atherosclerosis. With new methodologies, such as proteomics and metabolomics, discoveries of new clinically applicable biomarkers are expected.

BACKGROUND: Septic cardiomyopathy represents cardiac impairment in sepsis and is a part of systemic involvement in sepsis. Cytokine storm is responsible for septic shock and for myocardial dysfunction of potentially reversible septic cardiomyopathy. Several case reports and case series demonstrated successful removal of circulating cytokines by combined blood purification techniques. In this way, septic shock and survival of septic patients improved. However, the evidences for reversal of myocardial dysfunction are rare. CASE PRESENTATION: We present a patient with a history of chemotherapy for coat cell lymphoma, splenectomy and autologous bone marrow transplantation, who suffered severe pneumococcal sepsis, septic shock and septic cardiomyopathy, resistant to pharmacological therapy. Combined blood purification techniques 36 h after the start of treatment successfully decreased Interleukin-6 level, lactacidosis, the need for vasopressors to maintain normotension, improved systolic function of the left ventricle and clinical outcome. CONCLUSIONS: Our case suggests that combined blood purification techniques initiated even 36 h after the start of treatment successfully removed inflammatory cytokines, reversed circulatory failure and improved left ventricular systolic function in pneumococcal sepsis.

Therapeutic hypothermia was associated with increased mortality in patients with severe bacterial meningitis in a large randomized trial. It still remains a treatment strategy for comatose survivors of cardiac arrest. There are several potential advantages of inhalational anesthetics as long-term sedation agents compared to intravenous sedation, however, uncontrollable increases of intracranial pressure were observed in neurocritical patients. Here we present a patient with severe bacterial meningitis and secondary cardiac arrest where therapeutic hypothermia and inhalational anesthesia were successfully used. A 59-year old female with a history of a vestibular Schwannoma surgery on the left side was admitted with signs of meningitis. Within minutes after admission, she further deteriorated with respiratory arrest, followed by cardiac arrest. She remained comatose after return of spontaneous circulation. The standard treatment of severe meningitis (steroids, antibiotics, insertion of intracranial pressure probe and external ventricular drainage) along with therapeutic hypothermia and inhalational anesthesia were implemented. Intracranial pressure remained stable and daily neurological examination was possible without being confounded by concurrent sedation. She was discharged home without neurological sequelae after 27days. In selected patients with meningitis, therapeutic hypothermia may still present a treatment option, and the long-term use of inhalational anesthetics could be appropriate with concomitant intracranial pressure monitoring.

BACKGROUND: Subclinical left (LV) and right ventricular (RV) dysfunction has been demonstrated in type 2 diabetes mellitus and evidence indicates impaired LV diastolic function in type 1 diabetes mellitus (T1DM) as well. The aim of our study was to evaluate the role of tissue Doppler imaging (TDI) in assessment of global LV and RV function in T1DM patients. METHODS: A detailed two-dimensional, pulsed wave Doppler and pulsed wave TDI analysis was performed in 53 normotensive middle-aged T1DM patients and compared to healthy controls. RESULTS: In T1DM patients TDI analysis revealed reduced mean mitral septal and lateral E' velocities as well as reduced mean tricuspid EËt velocity compared to healthy controls (E'sept 8.89 ± 1.89 cm/s vs. 11.50 ± 2.41 cm/s, p < 0.001; E'lat 12.29 ± 2.58 cm/s vs.15.30 ± 2.95 cm/s, p < 0,001; E't 13.56 ± 2.91 cm/s vs. 15.60 ± 2.99 cm/s, p = 0.001). Mean ratios E/E'sept, E/E'lat and E/E't were significantly higher in diabetics with cutoff value of 7.4 for E/E'sept and 3.4 for E/E't, differentiating diabetics with LV and RV diastolic impairement from matched healthy controls (sensitivity 76.5 %, specificity 73.8 % for E/E'sept and sensitivity 72.1 %, specificity 66.7 % for E/E't). Myocardial acceleration during isovolumetric contraction (IVA) measured at the septal mitral (LV IVA) and lateral tricuspid annulus (RV IVA) was the only parameter indicating reduced contractility of both ventricles in diabetics compared to controls (LV IVA 230.70 ± 61.26 cm/s(2) vs. 283.32 ± 59.74 cm/s(2), p < 0,001; RV IVA 275.48 ± 68.08 cm/s(2) vs. 316.86 ± 80.95 cm/s(2), p = 0.011). LV IVA had better diagnostic accuracy than RV IVA to predict early contractile impairement in T1DM patients (area under the curve 0.758, p < 0.001 for LV IVA and 0.648, p = 0.017 for RV IVA). CONCLUSIONS: TDI is essential to detect subclinical diastolic deterioration of both ventricles in T1DM patients. TDI-derived IVA might be useful to assess early systolic alterations of both ventricles in T1DM patients.

BACKGROUND: Data about gender as an independent risk factor for death in ST-elevation myocardial infarction (STEMI) patients is still contrasting. Aim was to assess how gender influences in-hospital and long-term all-cause mortality in STEMI patients with primary percutaneous coronary intervention (PCI) in our region. METHODS: We analysed data from 2069 STEMI patients undergoing primary PCI in our institution from January 2009-December 2014, of whom 28.9% were women. In-hospital and long-term mortality were observed in women and men. The effect of gender on in-hospital mortality was assessed by binary logistic regression modelling and by Cox regression analysis for long-term mortality. RESULTS: Women were older (68.3±61.8 vs 61.8±12.0 years; p<0.0001), with a higher prevalence of diabetes (13.7% vs 9.9%; p=0.013) and tend to be more frequently admitted in cardiogenic shock (8.4% vs 6.3%; p =0.085). They were less frequently treated with bivalirudin (15.9% vs 20.3%; p=0.022). In-hospital mortality was higher among women (14.2% vs 7.8%; p<0.0001). After adjustment, age (adjusted OR: 1.05; 95% CI: 1.03 to 1.08; p < 0.001) and cardiogenic shock at admission (adjusted OR: 24.56; 95% CI: 11.98 to 50.35; p < 0.001), but not sex (adjusted OR: 1.47; 95% CI: 0.80 to 2.71) were identified as prognostic factors of in-hospital mortality. During the median follow-up of 27 months (25th, 75th percentile: 9, 48) the mortality rate (23.6% vs 15.1%; p<0.0001) was significantly higher in women. The multivariate adjusted Cox regression model identified age (HR 1.05; 95% CI 1.04-1.07; p<0.0001), cardiogenic shock at admission (HR 6.09; 95% CI 3.78-9.81; p<0.0001), hypertension (HR 1.49; 95% CI 1.02-2.18; p<0.046), but not sex (HR 1.04; 95% CI 0.74-1.47) as independent prognostic factors of follow-up mortality. CONCLUSION: Older age and worse clinical presentation rather than gender may explain the higher mortality rate in women with STEMI undergoing primary PCI.

BACKGROUND: Temperature management is a recommended part of post-resuscitation care of comatose survivors of cardiac arrest. A number of methods exist for temperature management, all of which have limitations. We aimed to evaluate the performance and ease of use of a new esophageal heat transfer device (EHTD; Advanced Cooling Therapy, Chicago, IL, USA) for temperature management of adult survivors of cardiac arrest. METHODS: We performed a prospective study from March to June 2015. Our standard protocol uses servo-controlled water blankets supplemented with ice-cold saline in order to attain goal temperature (32°C-34°C) within 1 hour. We substituted the EHTD for our usual water blankets, then recorded temperature over time and adverse effects. MAIN FINDINGS: A total of 14 patients were treated, with mean age 65.1±13.7 years, and median weight 75.5 (70; 83) kg. Initial temperature was 35.3±1.2°C. Mean cooling rate during the induction phase was 1.12±0.62°C/h, time to target temperature was 60 (41; 195) min and the volume of iced fluids infused was 1607±858 ml (as compared with 2-2.5L historically). The percentage of time outside target temperature range during the maintenance phase was 6.5% (0.0; 29.0). Rewarming rate was 0.22 (0.18; 0.31)°C/h. No major adverse effects were observed. CONCLUSION: Using the EHTD, our patient population attained goal temperatures in one hour, the volume of ice-cold saline required to attain this cooling rate was decreased by one-third, and experienced a low percentage of time outside target temperature range and no major adverse effects.

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is a novel early marker of acute kidney injury for which has been shown that it can also be released from the injured myocardium. Our aim was to correlate urine NGAL with markers of in-hospital heart failure in patients with acute ST-elevation myocardial infarction (STEMI). METHODS: We prospectively included 61 consecutive STEMI patients after primary percutaneous coronary intervention and estimated admission and in-hospital urine NGAL, serum creatinine, troponin I, leucocytes, CRP, N-terminal pro brain natriuretic peptide (NT-proBNP) levels and ejection fraction by echocardiography. Urine NGAL levels were compared between patients with and without HF defined as serum NT-proBNP > 400 pmol/l and were correlated to markers of heart failure, inflammations and of kidney function. RESULTS: Urine NGAL levels and CRP was significantly higher in participants with heart failure compared to those with NT-proBNP below 400 pmol/l. Urine NGAL level of 50 ng/ml had 90 % specificity for HF, the sensitivity was low at 25 %. Comparison of participants with NGAL levels < 50 ng/ml and ≥ 50 ng/ml at admission and after 12 h revealed a significant difference in NT-proBNP levels, left ventricle ejection fraction, markers of inflammation and of kidney function. Urine NGAL level was independently associated with NT-proBNP level. CONCLUSIONS: The level of urine NGAL early after myocardial infarction is associated with NT-proBNP concentration and even NGAL levels below 137 ng/ml, the usually reported normal cut-off value, had high specificity for HF in our sample.

BACKGROUND: Mild induced hypothermia is an established treatment strategy for comatose survivors of cardiac arrest. The goal of the induction phase of mild induced hypothermia is to cool the patient's core body temperature to 32°-34°C. OBJECTIVE: The main goal of this study was to compare temperature changes measured in the esophagus and urinary bladder in survivors of cardiac arrest undergoing mild induced hypothermia using cold saline infusion. METHODS: We performed a prospective study in a 12-bed adult medical intensive care unit at a tertiary level hospital in comatose adult survivors of nontraumatic cardiac arrest admitted from January to April 2012. Paired temperature readings from bladder and esophageal probes were recorded every 5 min for 95 min (20 readings). Cold fluid infusion was terminated when the measured temperature from either of the probes reached 33.9°C. Factorial repeated-measures analysis of variance was used to determine the effect of time and site of measurement on temperature readings. RESULTS: Measurements were performed in 8 patients. Target temperature was achieved in 33 ± 15 min in the esophagus and in 63 ± 15 min in the bladder (p = 0.006). We discovered a significant interaction effect (p < 0.001) between time and site of measurement, indicating that temperature changes differently depending on the site of measurement, with esophageal temperatures decreasing faster than temperatures measured in urinary bladder. CONCLUSIONS: Our results indicate that esophageal temperature measurements show a faster response rate compared to temperature measured in the bladder when cold saline infusion is used to induce mild hypothermia.

Several studies have been performed investigating the role of a real-time multiplex polymerase chain reaction assay LightCycler SeptiFast with inconsistent results. In prospective evaluation of adult patients with severe sepsis or septic shock SeptiFast assay and blood culture results were compared regarding concordance, the impact of SeptiFast assay on antimicrobial therapy adjustment, time to results and the role of SeptiFast assay as a marker of disease severity. 63 blood sample sets were collected from 57 patients. 51 (80.9%) results were concordant negative and 7 (11.1%) concordant posi- tive. In one (1.6%) sample set blood culture was positive and SeptiFast assay negative, in three (4.8%) sample sets with negative blood cultures pathogens were detected by SeptiFast assay and in one (1.6%)patient an additional pathogen was detected by SeptiFast assay. If blood culture is considered as "gold standard", 1 (1.6%) SeptiFast false negative and 4 (6.3%) false positive results were identified (sensitivity 87.5%, specificity 92.6%, negative predictive value 97.8%). Antibiotic treatment was adjusted according to SeptiFast assay in 4 (6.3%) cases. Time to final results was significantly shorter with SeptiFast assay (32 +/- 23 h vs. 97 +/- 28 h, p < 0.0001). Positive SeptiFast assay was not associated with higher mortality, C-reactive protein orprocalcitonin (p = 0.74, p = 0.44 and p = 0.12, respectively). According to our results SeptiFast assay can be used as a valuable add-on to blood culture in diagnostic workup ofpatients with severe sepsis and septic shock but it cannot replace the blood culture.

Purpose: There are well-known gender differences in mortality of patients with ST-elevation myocardial infarction (STEMI). Our purpose was to assess factors of hospital mortality separately for men and women with STEMI, which are less well known. Patients and Methods: In 2018-2019, 485 men and 214 women with STEMI underwent treatment with primary percutaneous coronary intervention (PCI). We retrospectively compared baseline characteristics, treatments and hospital complications between men and women, as well as between nonsurviving and surviving men and women with STEMI. Results: Primary PCI was performed in 94% of men and 91.1% of women with STEMI, respectively. The in-hospital mortality was significantly higher in women than in men (14% vs 8%, p=0.019). Hospital mortality in both genders was associated significantly to older age, heart failure, prior resuscitation, acute kidney injury, to less likely performed and less successful primary PCI and additionally in men to hospital infection and in women to bleeding. In men and women ≥65 years, mortality was similar (13.3% vs 17.8%, p = 0.293). Conclusion: Factors of hospital mortality were similar in men and women with STEMI, except bleeding was more likely observed in nonsurviving women and infection in nonsurviving men.
RESUMEN
INTRODUCTION: Lipoprotein(a) (Lp(a)) is a well-recognised risk factor for ischemic heart disease (IHD) and calcific aortic valve stenosis (AVS). METHODS: A retrospective observational study of Lp(a) levels (mg/dL) in patients hospitalised for cardiovascular diseases (CVD) in our clinical routine was performed. The Lp(a)-associated risk of hospitalisation for IHD, AVS, and concomitant IHD/AVS versus other non-ischemic CVDs (oCVD group) was assessed by means of logistic regression. RESULTS: In total of 11,767 adult patients, the association with Lp(a) was strongest in the IHD/AVS group (eß = 1.010, p < 0.001), followed by the IHD (eß = 1.008, p < 0.001) and AVS group (eß = 1.004, p < 0.001). With increasing Lp(a) levels, the risk of IHD hospitalisation was higher compared with oCVD in women across all ages and in men aged ≤75 years. The risk of AVS hospitalisation was higher only in women aged ≤75 years (eß = 1.010 in age < 60 years, eß = 1.005 in age 60-75 years, p < 0.05). CONCLUSIONS: The Lp(a)-associated risk was highest for concomitant IHD/AVS hospitalisations. The differential impact of sex and age was most pronounced in the AVS group with an increased risk only in women aged ≤75 years.

Lipoprotein(a) [Lp(a)] is a complex polymorphic lipoprotein comprised of a low-density lipoprotein particle with one molecule of apolipoprotein B100 and an additional apolipoprotein(a) connected through a disulfide bond. The serum concentration is mostly genetically determined and only modestly influenced by diet and other lifestyle modifications. In recent years it has garnered increasing attention due to its causal role in pre-mature atherosclerotic cardiovascular disease and calcific aortic valve stenosis, while novel effective therapeutic options are emerging [apolipoprotein(a) antisense oligonucleotides and ribonucleic acid interference therapy]. Bibliometric descriptive analysis and mapping of the research literature were made using Scopus built-in services. We focused on the distribution of documents, literature production dynamics, most prolific source titles, institutions, and countries. Additionally, we identified historical and influential papers using Reference Publication Year Spectrography (RPYS) and the CRExplorer software. An analysis of author keywords showed that Lp(a) was most intensively studied regarding inflammation, atherosclerosis, cardiovascular risk assessment, treatment options, and hormonal changes in post-menopausal women. The results provide a comprehensive view of the current Lp(a)-related literature with a specific interest in its role in calcific aortic valve stenosis and potential emerging pharmacological interventions. It will help the reader understand broader aspects of Lp(a) research and its translation into clinical practice.

Polyphenol antioxidants decrease the risk of atherosclerosis. The study aimed to evaluate prospectively in healthy young participants the effect of oral rosemary extracts (RE), consisting of diphenols, upon endothelial dysfunction (ED), preceding structural atherosclerosis. Nineteen healthy young volunteers were studied prospectively, who received oral RE (77.7 mg) for 21 days, consisting of active substances carnosol (0.97 mg), carnosic (8.60 mg) and rosmarinic acid (10.30 mg). Before and after RE treatment, the study evaluated fasting serum levels of plasminogen-activator-inhibitor-1 (PAI-1), vascular cell adhesion molecule 1 (VCAM-1), inter-cellular adhesion molecule 1 (ICAM-1), superoxide dismutase (SOD), glutathione peroxidase (GPX), fibrinogen, high-sensitivity capsular reactive protein (hs-CRP), tumor-necrosis factor α (TNF-α), the lipid profile and ED, characterized as flow-mediated dilatation (FMD) in the brachial artery of < 4.5%, estimated by ultrasound measurements. After 21 days, any side effects were registered, the mean FMD increased nonsignificantly (6.51 ± 5.96% vs 7.78 ± 4.56%, p = 0.546) and ED decreased significantly (66.6% vs 16.6%, p = 0.040). Among the serum markers, only the mean PAI-1 level decreased significantly (4.25 ± 1.46 U/mL vs 3.0 ± 0.61 U/mL, p = 0.012) after 21-day RE supplementation. It is concluded that oral RE supplementation has the potential to improve serum PAI-1 activity and ED in young and healthy individuals.

BACKGROUND: Air pollution with increased concentrations of fine (<2.5 µm) particulate matter (PM2.5) increases the risk of cardiovascular morbidity and mortality. Even short-term increase of PM2.5 may help trigger ST-elevation myocardial infarction (STEMI) and heart failure (HF) in susceptible individuals, even in areas with good air quality. PURPOSE: To evaluate the role of PM2.5 levels ≥20 µg/m3 in admission acute HF in STEMI patients. MATERIALS AND METHODS: In 290 STEMI patients with the leading reperfusion strategy primary percutaneous coronary intervention (PPCI), we retrospectively studied independent predictors of admission acute HF and included admission demographic and clinical data as well as ambient PM2.5 levels ≥20 µg/m3. We defined admission acute HF in STEMI patients as classes II-IV by Killip Kimball classification. RESULTS: Acute admission HF was observed in 34.5% of STEMI patients. PPCI was performed in 87.1% of acute admission HF patients and in 94.7% non-HF patients (p= 0.037). Significant independent predictors of acute admission HF were prior diabetes (OR 2.440, 95% CI 1.100 to 5.400, p=0.028), admission LBBB (OR 10.190, 95% CI 1.160 to 89.360, p=0.036), prior resuscitation (OR 2.530, 95% CI 1.010 to 6.340, p=0.048), admission troponin I≥5µg/l (OR 3.390, 95% CI 1.740 to 6.620, p<0.001), admission eGFR levels (0.61, 95% CI 0.52 to 0.72, p < 0.001), and levels of PM2.5 ≥20 µg/m3 (OR 2.140, 95% CI 1.005 to 4.560, p=0.049) one day before admission. CONCLUSION: Temporary short-term increase in PM2.5 levels (≥20 µg/m3) one day prior to admission in an area with mainly good air quality was among significant independent predictors of acute admission HF in STEMI patients.
RESUMEN
Several studies demonstrated a significant decrease in prescription errors, adverse drug events, treatment costs and improved patient outcomes, when a clinical pharmacist (CP) was a full member of a multidisciplinary team in the intensive care unit (ICU). Our aim was to evaluate the activities of a CP, included in a 12-bed medical ICU team of a university hospital in the course of several months. We conducted a retrospective analysis of all the CP's interventions from March 2017 to November 2017, carried out and documented after reviewing and discussing patients' medical data with the treating ICU physicians. We identified four main categories of CP's interventions: pharmacotherapy adjustments to kidney function (PAKF category), drug-drug interactions (DDIs category), therapeutic monitoring of drugs with narrow therapeutic index (TDM category), and drug administration by the nasogastric tube (NGT category). During the study period, 533 patients were admitted to the medical ICU. The CP reviewed the medical data of 321 patients and suggested 307 interventions in 95 patients. There were 147 interventions of the PAKF category, 57 interventions of the TDM category, 30 interventions of the NGT category, and 22 interventions of the DDIs category. Fifty-one interventions were unspecified. The majority of all interventions (203/307) were related to antimicrobial drugs. ICU physicians completely accepted 80.2% of the CP's suggestions. We observed that regular participation of the CP in the medical ICU team contributed to more individualized and improved pharmacological treatment of patients. Therefore, ICU teams should be encouraged to include CPs as regular team members.

Neurological outcome is an important determinant of death in admitted survivors after out-of-hospital cardiac arrest (OHCA). Studies demonstrated several significant pre-hospital predictors of ischemic brain injury (time to resuscitation, time of resuscitation, and cause of OHCA). Our aim was to evaluate the relationship between post-resuscitation clinical parameters and neurological outcome in OHCA patients, when all recommended therapeutic strategies, including hypothermia, were on board. We retrospectively included consecutive 110 patients, admitted to the medical ICU after successful resuscitation due to OHCA. Neurological outcome was defined by cerebral performance category (CPC) scale I-V. CPC categories I-II defined good neurological outcome and CPC categories III-V severe ischemic brain injury. Therapeutic measures were aimed to achieve optimal circulation and oxygenation, early percutaneous coronary interventions (PCI) in acute coronary syndromes (ACS), and therapeutic hypothermia to improve survival and neurological outcome of OHCA patients. We observed good neurological outcome in 37.2% and severe ischemic brain injury in 62.7% of patients. Severe ischemic brain injury was associated significantly with known pre-hospital data (older age, cause of OHCA, and longer resuscitations), but also with increased admission lactate, in-hospital complications (involuntary muscular contractions/seizures, heart failure, cardiogenic shock, acute kidney injury, and mortality), and inotropic and vasopressor support. Good neurological outcome was associated with early PCI, dual antiplatelet therapy, and better survival. We conclude that in OHCA patients, post-resuscitation early PCI and dual antiplatelet therapy in ACS were significantly associated with good neurological outcome, but severe ischemic brain injury was associated with several in-hospital complications and the need for vasopressor and inotropic support.
