RESUMEN
Background: Patients with ST-segment elevation myocardial infarction (STEMI) and COVID-19 infection have a worse clinical course and prognosis. The prognostic significance of the timing of STEMI in relation to COVID-19 infection was not investigated. Objectives: To assess whether the time of STEMI development in relation to COVID-19 infection (concurrent or following the infection) influenced the short-term prognosis. Methods: This was an observational study of consecutive COVID-19 patients with STEMI admitted to the COVID-hospital Batajnica (February 2021-March 2022). The patients were divided into the "STEMI first" group: patients with STEMI and a positive polymerase chain reaction test for COVID-19, and the "COVID-19 first" group: patients who developed STEMI during COVID-19 treatment. All patients underwent coronary angiography. The primary endpoint was in-hospital all-cause mortality. Results: The study included 87 patients with STEMI and COVID-19 (Mage, 66.7 years, 66% male). The "STEMI first" group comprised 54 (62.1%) patients, and the "COVID-19 first" group included 33 (37.9%) patients. Both groups shared a comparatively high burden of comorbidities, similar angiographic and procedural characteristics, and high percentages of performed percutaneous coronary interventions with stent implantation (90.7% vs. 87.9%). In-hospital mortality was significantly higher in the "COVID-19 first" group compared to the "STEMI first" group (51.5% vs. 27.8%). Following adjustment, the "COVID-19 first" group had a hazard ratio of 3.22 (95% confidence interval, 1.18-8.75, p = .022) for in-hospital all-cause death, compared with the "STEMI first" group (reference). Conclusion: Clinical presentation with COVID-19 infection, followed by STEMI ("COVID-19 first"), was associated with greater short-term mortality compared to patients presenting with STEMI and testing positive for COVID-19 ("STEMI first").

Introduction: Data on predictors and prognosis of hospital acquired pneumonia (HAP) in patients admitted for acute heart failure (AHF) to intensive care units (ICU) are scarce. Better knowledge of these factors may inform management strategies. This study aimed to assess the incidence and predictors of HAP and its impact on management and outcomes in patients hospitalised for AHF in the ICU. Methods: this was a retrospective single-centre observational study. Patient-level and outcome data were collected from an anonymized registry-based dataset. Primary outcome was in-hospital all-cause mortality and secondary outcomes included length of stay (LOS), requirement for inotropic/ventilatory support, and prescription patterns of heart failure (HF) drug classes at discharge. Results: Of 638 patients with AHF (mean age, 71.6 ± 12.7 years, 61.9% male), HAP occurred in 137 (21.5%). In multivariable analysis, HAP was predicted by de novo AHF, higher NT proB-type natriuretic peptide levels, pleural effusion on chest x-ray, mitral regurgitation, and a history of stroke, diabetes, and chronic kidney disease. Patients with HAP had a longer LOS, and a greater likelihood of requiring inotropes (adjusted odds ratio, OR, 2.31, 95% confidence interval, CI, 2.16-2.81; p < 0.001) or ventilatory support (adjusted OR 2.11, 95%CI, 1.76-2.79, p < 0.001). After adjusting for age, sex and clinical covariates, all-cause in-hospital mortality was significantly higher in patients with HAP (hazard ratio, 2.10; 95%CI, 1.71-2.84; p < 0.001). Patients recovering from HAP were less likely to receive HF medications at discharge. Discussion: HAP is frequent in AHF patients in the ICU setting and more prevalent in individuals with de novo AHF, mitral regurgitation, higher burden of comorbidities, and more severe congestion. HAP confers a greater risk of complications and in-hospital mortality, and a lower likelihood of receiving evidence-based HF medications at discharge.
RESUMEN
OBJECTIVES: The influence of the bleeding site on long-term survival after the primary percutaneous coronary intervention (PCI) is poorly understood. This study sought to investigate the relationship between in-hospital access site versus non-access site bleeding and very late mortality in unselected patients treated with primary PCI. METHODS: Data of the 2715 consecutive patients with ST-segment elevation myocardial infarction treated with primary PCI, enrolled in a prospective registry of a high volume tertiary centre, were analysed. Bleeding events were assessed according to the Bleeding Academic Research Consortium (BARC) criteria. The primary outcome was 4-year mortality. RESULTS: The BARC type ≥2 bleeding occurred in 171 patients (6.3%). Access site bleeding occurred in 3.8%, and non-access site bleeding in 2.5% of patients. Four-year mortality was significantly higher for patients with bleeding (BARC type ≥2) than in patients without bleeding (BARC type 0+1), (36.3% vs 16.2%, p<0.001). Patients with non-access site bleeding had higher 4 year mortality (50.7% vs 26.5%, p=0.001). After multivariable adjustment, BARC type ≥2 bleeding was the independent predictor of 4 year mortality (HR 2.01; 95% CI 1.49 to 2.71, p<0.001). Patients with a non-access site bleeding were at 2-fold higher risk of very late mortality than patients with an access site bleeding (HR 2.62; 1.78 to 3.86, p<0.001 vs HR 1.57; 1.03 to 2.38, p=0.034). CONCLUSIONS: Both access and non-access site BARC type ≥2 bleeding is independently associated with a high risk of 4-year mortality after primary PCI. Patients with non-access site bleeding were at higher risk of late mortality than patients with access site bleeding.

Previous studies compared clinical outcomes of early versus delayed invasive strategy in patients with non-ST-elevation acute coronary syndrome up to 1-year follow-up, but long-term data remain scarce. Our aim was to evaluate the long-term effects of immediate invasive intervention in patients with Non-ST-Segment Elevation Myocardial Infarction (NSTEMI). The Randomized Study of Immediate Versus Delayed Invasive Intervention in Patients With Non-ST-Segment Elevation Myocardial Infarction (RIDDLE-NSTEMI) was a randomized, investigator-initiated, parallel-group trial that assigned 323 patients with NSTEMI (1:1) to either immediate (median time to intervention 1.4 hours) or delayed invasive strategy (61.0 hours). The primary end point was the composite of death or new myocardial infarction (MI). At 3 years, immediate invasive intervention was associated with a lower rate of death or new MI, compared with a delayed invasive strategy (12.3% vs 22.5%, hazard ratio 0.50, 95% confidence interval 0.29 to 0.87, p = 0.014). The observed benefit of immediate intervention was mainly driven by an increased early reinfarction risk in delayed strategy, with similar new MI rates beyond 30 days (4.4% in the immediate and 5.6% in the delayed group, p = 0.61). Three-year mortality was 9.3% in the immediate invasive strategy, and 10.0% in the delayed strategy (p = 0.83). High baseline Global Registry of Acute Coronary Events score (>140) was associated with a significant increase in long-term mortality, regardless of the timing of invasive intervention. In conclusion, whereas immediate invasive intervention significantly reduced the early risk of new MI, the timing of invasive intervention appears to have no significant impact on clinical outcomes beyond 30 days, which seem to mostly be related to the baseline clinical risk profile.

BACKGROUND: A routine invasive strategy is recommended for patients with non-ST-elevation acute coronary syndromes (NSTE-ACS). However, optimal timing of invasive strategy is less clearly defined. Individual clinical trials were underpowered to detect a mortality benefit; we therefore did a meta-analysis to assess the effect of timing on mortality. METHODS: We identified randomised controlled trials comparing an early versus a delayed invasive strategy in patients presenting with NSTE-ACS by searching MEDLINE, Cochrane Central Register of Controlled Trials, and Embase. We included trials that reported all-cause mortality at least 30 days after in-hospital randomisation and for which the trial investigators agreed to collaborate (ie, providing individual patient data or standardised tabulated data). We pooled hazard ratios (HRs) using random-effects models. This meta-analysis is registered at PROSPERO (CRD42015018988). FINDINGS: We included eight trials (n=5324 patients) with a median follow-up of 180 days (IQR 180-360). Overall, there was no significant mortality reduction in the early invasive group compared with the delayed invasive group HR 0·81, 95% CI 0·64-1·03; p=0·0879). In pre-specified analyses of high-risk patients, we found lower mortality with an early invasive strategy in patients with elevated cardiac biomarkers at baseline (HR 0·761, 95% CI 0·581-0·996), diabetes (0·67, 0·45-0·99), a GRACE risk score more than 140 (0·70, 0·52-0·95), and aged 75 years older (0·65, 0·46-0·93), although tests for interaction were inconclusive. INTERPRETATION: An early invasive strategy does not reduce mortality compared with a delayed invasive strategy in all patients with NSTE-ACS. However, an early invasive strategy might reduce mortality in high-risk patients. FUNDING: None.

BACKGROUND: There is conflicting information about sex differences in presentation, treatment, and outcome after acute coronary syndromes (ACS) in the era of reperfusion therapy and percutaneous coronary intervention. The aim of this study was to examine presentation, acute therapy, and outcomes of men and women with ACS with special emphasis on their relationship with younger age (≤65years). METHODS: From January 2010 to June 2015, we enrolled 5140 patients from 3 primary PCI capable hospitals. Patients were registered according to the International Survey of Acute Coronary Syndrome in Transitional Countries (ISACS-TC) registry protocol (ClinicalTrials.gov: NCT01218776). The primary outcome was the incidence of in-hospital mortality. RESULTS: The study population was constituted by 2876 patients younger than 65years and 2294 patients older. Women were older than men in both the young (56.2±6.6 vs. 54.1±7.4) and old (74.9±6.4 vs. 73.6±6.0) age groups. There were 3421 (66.2%) patients with ST elevation ACS (STE-ACS) and 1719 (33.8%) patients without ST elevation ACS (NSTE-ACS). In STE-ACS, the percentage of patients who failed to receive reperfusion was higher in women than in men either in the young (21.7% vs. 15.8%) than in the elderly (35.2% vs. 29.6%). There was a significant higher mortality in women in the younger age group (age-adjusted OR 1.52, 95% CI: 1.01-2.29), but there was no sex difference in the older group (age-adjusted OR 1.10, 95% CI: 0.87-1.41). Significantly sex differences in mortality were not seen in NSTE-ACS patients. CONCLUSIONS: In-hospital mortality from ACS is not different between older men and women. A higher short-term mortality can be seen only in women with STEMI and age of 65 or less.

OBJECTIVES: This study aimed to assess the clinical impact of immediate versus delayed invasive intervention in patients with non-ST-segment myocardial infarction (NSTEMI). BACKGROUND: Previous studies found conflicting results on the effects of earlier invasive intervention in a heterogeneous population of acute coronary syndromes without ST-segment elevation. METHODS: We randomized 323 NSTEMI patients to an immediate-intervention group (<2 h after randomization, n = 162) and a delayed-intervention group (2 to 72 h, n = 161).The primary endpoint was the occurrence of death or new myocardial infarction (MI) at 30-day follow-up. RESULTS: Median time from randomization to angiography was 1.4 h and 61.0 h in the immediate-intervention group and the delayed-intervention group, respectively (p < 0.001). At 30 days, the primary endpoint was achieved less frequently in patients undergoing immediate intervention (4.3% vs. 13%, hazard ratio: 0.32, 95% confidence interval: 0.13 to 0.74; p = 0.008). At 1 year, this difference persisted (6.8% in the immediate-intervention group vs. 18.8% in delayed-intervention group; hazard ratio: 0.34, 95% confidence interval: 0.17 to 0.67; p = 0.002). The observed results were mainly attributable to the occurrence of new MI in the pre-catheterization period (0 deaths + 0 MIs in the immediate-intervention group vs. 1 death + 10 MIs in the delayed-intervention group). The rate of deaths, new MI, or recurrent ischemia was lower in the immediate-intervention group at both 30 days (6.8% vs. 26.7%; p < 0.001) and 1 year (15.4% vs. 33.1%; p < 0.001). CONCLUSIONS: Immediate invasive strategy in NSTEMI patients is associated with lower rates of death or new MI compared with the delayed invasive strategy at early and midterm follow-up, mainly due to a decrease in the risk of new MI in the pre-catheterization period.

BACKGROUND: Previous randomized controlled trials (RCTs) have produced conflicting results on the effects of early versus delayed invasive strategy in NSTE-ACS patients. OBJECTIVES: To perform up to date meta-analysis on the pooled data sample comparing early versus delayed invasive strategy, and to explore potential causes for the observed high statistical heterogeneity. METHODS: MEDLINE via Pubmed, Central, Google Scholar, Clinical Trials Registry, Current controlled study and ClinicalTrials.gov registry and relevant conference proceedings were searched. RCTs were included that directly compared early versus delayed invasive strategy and reported rates of death, new myocardial infarction (MI) and/or recurrent ischemia. RESULTS: 10 RCTs with 6089 patients were included. Time to coronary angiography varied from 0.5 to 24 h in the early and from 20.5 to 86 h in the delayed group. Meta-analysis showed no significant difference in mortality (OR = 0.83, 95%CI 0.64-1.08, P = 0.16), and similar new MI rates (OR = 1.02, 95%CI 0.63-1.64, P = 0.94). The rate of recurrent ischemia was reduced in patients undergoing early coronary angiography (OR = 0.56, 95%CI 0.40-0.79, P = 0.001). Subgroup analysis indicated that the rate of new MI tended to depend on the study-specific endpoint definition (p for difference between subgroups 0.11), while a meta-regression revealed association of new MI rates with the within-study delay to coronary angiography (p = 0.05). CONCLUSION: Early invasive strategy appears to reduce the occurrence of recurrent ischemia, but confers no mortality benefit. The true effect on the occurrence of new MI is obscured by the high between-study heterogeneity that stems mainly from non-uniform timing of early intervention and new MI definitions across the trials.

INTRODUCTION: Treating severe acute glyphosate-surfactant poisoning requires intensive therapy including dialysis. Cases of hemoperfusion and hemodialysis use in renal failure induced by herbicide ingestion have been reported in the current medical literature. We present a case report of successful patient treatment with continuous venovenous hemodiafiltration in acute glyphosate-surfactant poisoning. CASE OUTLINE: A 36-year-old male patient attempted suicide by drinking approximately 300 ml of glyphosate-surfactant about an hour before coming to our Clinic. On admittance the patient was somnolent, normotensive, acidotic and hyperkalemic. Six hours after poison ingestion there was no positive response to symptomatic and supportive therapy measures. The patient became hypotensive, hypoxic with oliguric acute renal failure, so that post-dilution continuous veno-venous hemodiafiltration was started. During the treatment the patient became hemodinamically stabile, diuresis was established along with electrolyte and acid-base status correction and a gradual decrease of blood urea nitrogen and creatinine levels. After a single 27.5-hour treatment, clinical condition and renal function parameters did not require further dialysis. Complete recovery of renal function was achieved on the fifth day. CONCLUSION: Early introduction of continuous veno-venous hemodiafiltration with other intensive therapy measures led to complete recovery in a hemodinamically instable patient.

BACKGROUND/AIM: In patients with end-stage renal disease, treatment with erythropoietin lowers cardiovascular morbidity, improves quality of life and patient survival. The aim of this study was to determine the difference in survival of hemodialysis patients treated with recombinant human beta erythropoietin and patients without this treatment, and to determine the influence of hemoglobin level and erythropoietin dose on the survival of these patients. METHOD: The study included 291 patients undergoing maintenance hemodialysis, 122 were on erythropoietin therapy, 169 patients formed control group. The study was performed at the Clinic for Nephrology and Clinical Immunology, Clinical Center of Vojvodina, during a 69-month period. We analyzed basic demographic parameters, dialysis duration, underlying disease, comorbidities, death causes, blood-work parameters and erythropoietin dosage. Descriptive statistics, Anova, Manova, discriminant function analysis, Cox regressional model and Kaplan Meier survival curves were used as statistical methods. RESULTS: Average age and dialysis duration in the experimental group were 47.88 +/- 13.32 years, and 45.76 +/- 46.73 months, respectively and in the control group 58.73 +/- 12.67 years and 62.80 +/- 55.23 months, respectively. Average level of hemoglobin and hematocrit in the group in which erythropoietin had been administered was 11.40 +/- 8.39 g/dL and 0.35 +/- 0.04/L, while the control group these values were 8.52 +/- 7.73 g/dL and 0.26 +/- 0.04/L, respectively. Average monthly dosage of erythropoietin was 21 587 +/- 10 183.36 IJ/month. Significant difference in survival was determined (p < 0.05) between the stated patient groups. A significant difference (p < 0.05) was found in survival of the patients in which erythropoietin was administered regarding hemoglobin level (< 100 g/L/100-110 g/L/110-120 g/L/ > 120 g/L), as well as in regard of erythropoietin dose applied (< 20 000 IJ/20 000-40 000 IJ/ > 40 000 IJ/month). CONCLUSION: Best survival was noted in patients with hemoglobin > 120 g/L and erythropoietin dose < 20 000 IJ/month.

INTRODUCTION: Primary glomerulonephritis can be treated by the intravenous use of cyclophosphamide. The aim of our study is to evaluate the effect of the drug in the treatment of mentioned diseases and the follow-up of complications. MATERIAL AND METHODS: There are 30 patients included in this study, mean-age of 46.83 years. Renal biopsy was performed in 25 patients. Membranoproliferative glomerulonephritis was diagnosed in 36.67% of patients, mesangioproliferative in 16.67%, rapidly progressive in 13,33%, membranous in 10%, chronic in 10%, primary focal segmental glomerulosclerosis in 3,33% and 10% of patients were unclassified They have been treated with cyclophosphamide in intermittent "pulse" doses: once a month fbr the first 6 months and once in 3 months, for 18 months or longer, after that. RESULTS AND DISCUSSION: The drug was given in the recommended dose of 0.5-lg/m of body-surface area, in the combination with a low-dose corticosteroides. Hematological and renal fimnctional tests were checked before every "pulse" dose. Concerning the development of the renal ailure the fivorable effect occurred in 50% of patients. Proteinuria was found in all patients (80% >3.5 gr/24 h). The favorable effect occurred in 80% patients. At the end, serum proteins were normal in 76.67% patients. 30% of patients normalized the erythrocyte sedimentation level. Remission has not been achieved in 23.33% of patients, 10% of patients developed relapse. 20% of patients died infections were the most common complication and they occurred in 30% of patients. Sepsis, leucopenia, Herpes Zoster infection and hemorrhagic cystitis have not occurred in any patient. Malignant tumor was found in 6.67% of patients.
