Association of serum glucose/potassium index levels with poor long-term prognosis in patients with Aneurysmal Subarachnoid Hemorrhage

IntroductionThe glucose/potassium index (GPI) has been reported as a predictor biomarker of in-hospital complications in patients with aneurysmal subarachnoid hemorrhage (aSAH). ObjectivesTo determine the association between GPI and functional outcome at 3–6 months after discharge in patients diagnosed with aSAH in a Peruvian referral hospital during 2018–2021. Materials and MethodsWe conducted a retrospective cohort observational study with a secondary database in patients with aSAH during 2018–2021 in a Peruvian referral hospital. We evaluated the relationship between GPI values and motor functionality from 3 m to 6 months post-discharge, using a Poisson family generalized linear model with Log link function and robust variance according to categorization of good and poor outcome. We considered a value of p<0.05 as statistically significant. We used restricted cubic splines with five nodes to evaluate the linear correlation between the 2 main variables. Results212 patients were included in the analysis. 21.1 % and 19.3 % had poor outcome at 3 and 6 months after discharge, respectively. Multivariate analysis showed that GPI was not associated with poor outcome at 3 (RR=0.999; 95 %CI=0.979–1.018) or 6 months after discharge (RR=0.979; 95 %CI=0.979–1.020). On the other hand, Splines plots showed no correlation between GPI and modified Rankin. ConclusionsDespite the usefulness of GPI to prognosticate in-hospital complications, its association with functional outcome is inconclusive.

The Elevated Inflammatory Status of Neutrophils Is Related to In-Hospital Complications in Patients with Acute Coronary Syndrome and Has Important Prognosis Value for Diabetic Patients.

Despite neutrophil involvement in inflammation and tissue repair, little is understood about their inflammatory status in acute coronary syndrome (ACS) patients with poor outcomes. Hence, we investigated the potential correlation between neutrophil inflammatory markers and the prognosis of ACS patients with/without diabetes and explored whether neutrophils demonstrate a unique inflammatory phenotype in patients experiencing an adverse in-hospital outcome. The study enrolled 229 ACS patients with or without diabetes. Poor evolution was defined as either death, left ventricular ejection fraction (LVEF) <40%, Killip Class 3/4, ventricular arrhythmias, or mechanical complications. Univariate and multivariate analyses were employed to identify clinical and paraclinical factors associated with in-hospital outcomes. Neutrophils isolated from fresh blood were investigated using qPCR, Western blot, enzymatic assay, and immunofluorescence. Poor evolution post-myocardial infarction (MI) was associated with increased number, activity, and inflammatory status of neutrophils, as indicated by significant increase of Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), fibrinogen, interleukin-1β (IL-1β), and, interleukin-6 (IL-6). Among the patients with complicated evolution, neutrophil activity had an important prognosis value for diabetics. Neutrophils from patients with unfavorable evolution revealed a pro-inflammatory phenotype with increased expression of CCL3, IL-1β, interleukin-18 (IL-18), S100A9, intracellular cell adhesion molecule-1 (ICAM-1), matrix metalloprotease (MMP-9), of molecules essential in reactive oxygen species (ROS) production p22phox and Nox2, and increased capacity to form neutrophil extracellular traps. Inflammation is associated with adverse short-term prognosis in acute ACS, and inflammatory biomarkers exhibit greater specificity in predicting short-term outcomes in diabetics. Moreover, neutrophils from patients with unfavorable evolution exhibit distinct inflammatory patterns, suggesting that alterations in the innate immune response in this subgroup may exert detrimental effects on disease progression.

Prediction of in-hospital complications in takotsubo syndrome: prospective cohort study

BACKGROUND: Until recently, takotsubo syndrome (TS) was considered a fairly benign disease in both early and late periods. However, in recent years, in-hospital complications in the acute period of TS are common and can be life-threatening.&#x0D; AIM: Based on clinical and laboratory-instrumental data, this study aimed to build models for predicting the risk of developing in-hospital complications in patients with TS during the acute period.&#x0D; MATERIALS AND METHODS: This prospective cohort study included 60 patients with TS, with an average age of 65.5±13.4 years. In the acute period (7–14 days), standard clinical and laboratory examination, peripheral arterial tonometry using the «EndoPAT 2000» apparatus, and psychological testing using validated questionnaires (hospital anxiety and depression scale and Beck depression scale) were performed.&#x0D; RESULTS: The integrated model for predicting the risk of acute heart failure (AHF) development (pulmonary edema and cardiogenic shock) identified admission LVEF as the leading prognostic parameter. With LVEF ≤40.5%, the probability of AHF in patients with TS in the acute period was 62.5%, and in patients with TS and QTc interval 487 ms, the risk reached 100%. The sensitivity and specificity of the developed model were 72.7% and 97.4%, respectively. The integrated model for predicting the development of cardiovascular complications (CVCs) revealed that the number of leukocytes in the peripheral blood was the leading risk factor for adverse events in patients with TS in the acute period. With a leukocyte count 11.1×109/L, the risk of CVCs in patients with TS increased to 89.9%, and if the erythrocyte count was 4.69×1012/L or ≤4.29×1012/L, it could reach 100%. The sensitivity and specificity of the resulting model were 92.6 and 97.0%, respectively.&#x0D; CONCLUSION: The models proposed in this study for predicting the likelihood of developing severe AHF and the overall risk of CVCs in the acute period of TS are personalized and easy to use, allowing for the selection of optimized treatment techniques.

Determinants of serious in-hospital complications in patients with Killip class 1/2 ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention.

Killip classification has been used to stratify the risk of patients with acute myocardial infarction (AMI). There were many reports that Killip class 3 or 4 is closely associated with poor clinical outcomes. In other words, Killip class 1 or 2 is associated with favorable clinical outcomes in patients with AMI, especially when patients received primary percutaneous coronary intervention (PCI). However, some patients with Killip class 1/2 suffer from serious in-hospital complications. This study aimed to identify factors associated with serious in-hospital complications of ST-segment elevation myocardial infarction (STEMI) in patients with Killip class 1/2. The primary endpoint was serious in-hospital complications defined as the composite of in-hospital death and mechanical complications. We included 809 patients with STEMI, and divided them into the non-complication group (n = 791) and the complication group (n = 18). In-hospital death was observed in 14 patients (1.7%), and mechanical complications were observed in 4 patients (0.5%). Final TIMI flow ≤ 2 was more frequently observed in the complication group (33.3%) than in the non-complication group (5.4%) (p < 0.001). Multivariate logistic regression analysis revealed that serious in-hospital complication was associated with final TIMI flow grade ≤ 2 (Odds ratio 6.040, 95% confidence interval 2.042-17.870, p = 0.001). In conclusion, serious in-hospital complication of STEMI was associated with insufficient final TIMI flow grade in patients with Killip class 1/2. If final TIMI flow grade is suboptimal after primary PCI, we may recognize the potential risk of serious complications even when patients presented as Killip class 1/2.

Complications and Outcomes in 39,864 Patients Receiving Standard Care Plus Mechanical Circulatory Support or Standard Care Alone for Infarct-Associated Cardiogenic Shock.

Temporary mechanical circulatory support devices (tMCS) are increasingly being used in patients with infarct-associated cardiogenic shock (AMICS). Evidence on patient selection, complications and long-term outcomes is lacking. We aim to investigate differences in clinical characteristics, complications and outcomes between patients receiving no tMCS or either intra-aortic balloon pump (IABP), veno-arterial extracorporeal membrane oxygenation (V-A ECMO) or Impella® for AMICS, with a particular focus on long-term outcomes. Using health claim data from AOK-Die Gesundheitskasse (local health care funds), we retrospectively analysed complications and outcomes of all insured patients with AMICS between 1 January 2010 and 31 December 2017. A total of 39,864 patients were included (IABP 5451; Impella 776; V-A ECMO 833; no tMCS 32,804). In-hospital complications, including renal failure requiring dialysis (50.3% V-A ECMO vs. 30.5% Impella vs. 29.2 IABP vs. 12.1% no tMCS), major bleeding (38.1% vs. 20.9% vs. 18.0% vs. 9.3%) and sepsis (22.5% vs. 15.9% vs. 13.9% vs. 9.3%) were more common in V-A ECMO patients. In a multivariate analysis, the use of both V-A ECMO (HR 1.57, p < 0.001) and Impella (HR 1.25, p < 0.001) were independently associated with long-term mortality, whereas use of IABP was not (HR 0.89, p < 0.001). Kaplan-Meier estimates showed better survival for patients on IABP compared with Impella, V-A ECMO and no-tMCS. Short- and long-term mortality was high across all groups. Our data show noticeably more in-hospital complications in patients on tMCS and higher mortality with V-A ECMO and Impella. The use of both devices is an independent risk factor for mortality, whereas the use of IABP is associated with a survival benefit.

Monocyte to high-density lipoprotein ratio is associated with mortality in patients with coronary artery diseases

BackgroundWhether the monocyte to high-density lipoprotein ratio (MHR) is associated with the prognosis of coronary artery disease (CAD) is inconclusive.MethodsPatients with CAD were enrolled and their data were collected. Blood was sampled within 24 h after admission. Multivariate Cox regression analysis was performed to determine the relationship between the MHR and all-cause mortality as well as complications during hospitalization.ResultsWe included 5371 patients in our cohort study. Among them, 114 (2.12%) patients died in hospital. MHR was independently associated with all-cause mortality (hazard ratio [HR], 1.81; 95% confidence interval [CI] 1.35, 2.42), cardiovascular mortality (1.69; 1.17, 2.45) and non-cardiovascular mortality (2.04; 1.27, 3.28). This association was only observed in patients with hypertension (P for interaction = 0.003). Patients with higher MHR levels also have a higher risk of complications, including infection, pneumonia, electrolyte disturbance, gastrointestinal bleeding, multiple organ dysfunction syndrome, and disturbance of consciousness. The receiver operating characteristic (ROC) analysis showed that the MHR had higher prognostic values than monocytes and high-density lipoprotein.ConclusionMHR was an independent predictor of all-cause mortality and in-hospital complications in patients with CAD, especially in patients with hypertension.

Inflammatory Burden Index: Association Between Novel Systemic Inflammatory Biomarkers and Prognosis as Well as in-Hospital Complications of Patients with Aneurysmal Subarachnoid Hemorrhage.

Systemic inflammation plays an important role in the pathophysiology and progression of aneurysmal subarachnoid hemorrhage (aSAH). In this study, we aimed to investigate the association between a new biomarker, the inflammatory burden index (IBI) and the prognosis as well as in-hospital complications of aSAH patients. We analyzed data from patients with aSAH between January 2019 and September 2022 who were included in the LongTEAM (Long-term Prognosis of Emergency Aneurysmal Subarachnoid Hemorrhage) registry study. The IBI was formulated as C-reactive protein × neutrophils/lymphocytes. The unfavorable functional prognosis was assessed by the modified Rankin Scale (mRS). Receiver operating characteristic (ROC) curve analysis was conducted to determine the optimal cut-off values for IBI to distinguish the unfavorable functional prognosis. Multivariate logistic regression was applied to investigate the association between IBI and in-hospital complications. Propensity score matching was adjusted for imbalances in baseline characteristics to assess the effect of IBI on prognosis. A total of 408 consecutive patients with aSAH enrolled in the study, of which 235 (57.6%) were female patients and the mean age was 55.28 years old. An IBI equal to 138.03 was identified as the best cut-off threshold to distinguish the unfavorable prognosis at 3 months (area under the curve [AUC] [95% CI] 0.637 [0.568-0.706]). ln IBI was independently associated with 3-month functional prognosis (OR [95% CI] 1.362 [1.148-1.615]; P<0.001), pneumonia (OR [95% CI] 1.427 [1.227-1.659]; P<0.001) and deep venous thrombosis (DVT). (OR [95% CI] 1.326 [1.124-1.564]; P=0.001). After propensity score matching (57:57), an increased proportion of patients with IBI ≥138.03 had a poor functional prognosis at 3 months and in-hospital complications including developed pneumonia and DVT. In patients with aSAH, high IBI level at admission was associated with unfavorable functional prognosis as well as pneumonia and deep vein thrombosis.

Acute kidney injury is a risk factor for in-hospital mortality in patients with acute cardiovascular pathology and concomitant COVID-19

Abstract Funding Acknowledgements Type of funding sources: None. Although respiratory failure and hypoxemia are the main manifestations of COVID-19, many patients also experience worsening kidney function. Hemodynamic disorders in patients with acute cardiovascular pathology can also worsen renal function. The aim of this study was to assess kidney function and its significance for the development of in-hospital complications in patients who were hospitalized with acute cardiovascular pathology and had a co-infection with COVID-19. 139 pts with acute cardiovascular pathology who were diagnosed with COVID-19 were examined. 69 (49.6%) pts had ACS (47 pts with AMI), 33 (23.7%) pts - hypertensive urgency, 24 (17.3%) pts - ADHF, 9 (6.5%) pts - tachysystolic paroxysm of atrial fibrillation, 2 (1.4%) pts - acute pulmonary embolism, and 2 (1.4%) pts - syncope. The average age was 67.9±12.7 y.o., 70 (50.4%) pts were male. Concomitant arterial hypertension was found in 87.1%, DM – 20.9%, CHF - 30.9%, COPD – 9.4% of pts, history of AMI – 20.1% and ischemic stroke – 9.4% of pts. The initial creatinine level was 110.7±66.1 μmol/l, eGFR CKD-EPI - 63.3±20.3 ml/min/1.73m2 (eGFR&amp;lt;60 ml/min/1 ,73m2 – 46.0% of patients). Patients with eGFR&amp;lt;60 ml/min/1.73m2 were older, more often female, often had a history of AF, had a lower level of hemoglobin and blood pressure at admission, a greater number of complications (need for NIV, inotropic therapy) and higher in-hospital mortality (25.0% vs. 5.3%, p=0.002). Acute kidney injury, which was evaluated according to KDIGO criteria (creatinine level increase ≥ 26.5 μmol/l within 48 hours or ≥ 1.5 times within 7 days) was observed in 21 (15.4%) patients (12.0% in patients with eGFR≥60 ml/min/1.73m2 and 18.8% with eGFR&amp;lt;60 ml/min/1.73m2, p&amp;lt;0.05). These patients did not significantly differ from patients without AKI in terms of basic clinical and anamnestic characteristics, but had a lower spO2 level at admission (86.9±11.2% vs. 93.4±5.0%, p=0.016). Patients with AKI had a significantly higher number of in-hospital complications: acute hypoxic delirium (47.6% vs. 8.7%, p=0.003), VTE (14.3% vs. 0.9%, p=0.070), death from of all causes (47.6% vs. 7.0%, p=0.002) and more often required organ support therapy: non-invasive/invasive lung ventilation (52.4% vs. 11.3%, p&amp;lt;0.001), inotropic therapy (57, 1% versus 5.2%, p&amp;lt;0.001). The simplified criterion of AKI (increase of creatinine level ≥ 26.5 μmol/l in comparison with the value at admission at any time during the hospital period) also made it possible to distinguish the category of patients at high risk of hospital complications and death (37.9% vs. 8.2% , p=0.004). Acute kidney injury is a powerful risk factor for in-hospital complications and mortality in patients with acute cardiovascular pathology and concomitant COVID-19 infection.

Risk factors for in-hospital complications in patients with acute ischemic stroke: Retrospective cohort in a national reference hospital in Peru

ObjectiveTo describe the clinical and demographic characteristics of patients with acute cerebral infarction treated at a national reference hospital in Peru and determine the risk factors for in-hospital complications. MethodsWe conducted a retrospective cohort study including 192 patients with acute ischemic stroke in a national reference hospital in Peru from January to September 2021. Clinical, demographic and paraclinical information was recorded from medical records. We estimated risk ratios and 95% confidence intervals using regression models with Poisson family and robust variance for the bivariate and multivariate model, adjusting for age, sex and risk factors for stroke. ResultsAt least one in-hospital complication occurred in 32.3% of the patients. The most frequent complications were infectious in 22.4%, followed by 17.7% of neurological complications, with other complications, such as thromboembolism, immobility and miscellaneous, being much less frequent. Regression analysis showed that stroke severity (RR = 1.76; 95%CI:1.09–2.86) and albumin greater than 3.5 mg/dL (RR = 0.53; 95%CI: 0.36–0.79) were independent risk factors for the presence of in-hospital complications. ConclusionsA high rate of in-hospital complications were observed, among which infectious and neurological complications were the most frequent. Stroke severity was a risk factor and albumin greater than 3.5 mg/dL was a protective factor for the incidence of in-hospital complications. These results can serve as a starting point for establishing stroke care systems that consider differentiated flows for the prevention of in-hospital complications.

Use of the cardiopulmonary coupling index based on refined composite multiscale entropy for prognostication of acute type A aortic dissection.

The aim of this study is to assess the influence of cardiopulmonary coupling (CPC) based on RCMSE on the prediction of complications and death in patients with acute type A aortic dissection (ATAAD). The cardiopulmonary system may be nonlinearly regulated, and its coupling relationship with postoperative risk stratification in ATAAD patients has not been studied. This study was a single-center, prospective cohort study (ChiCTR1800018319). We enrolled 39 patients with ATAAD. The outcomes were in-hospital complications and all-cause readmission or death at 2 years. Of the 39 participants, 16 (41.0%) developed complications in the hospital, and 15 (38.5%) died or were readmitted to the hospital during the two-year follow-up. When CPC-RCMSE was used to predict in-hospital complications in ATAAD patients, the AUC was 0.853 (p < 0.001). When CPC-RCMSE was used to predict all-cause readmission or death at 2 years, the AUC was 0.731 (p < 0.05). After adjusting for age, sex, ventilator support (days), and special care time (days), CPC-RCMSE remained an independent predictor of in-hospital complications in patients with ATAAD [adjusted OR: 0.8 (95% CI, 0.68-0.94)]. CPC-RCMSE was an independent predictor of in-hospital complications and all-cause readmission or death in patients with ATAAD.

Kidney dysfunction and in-hospital complications in patients with acute cardiovascular pathology infected with COVID-19

This study aimed to assess kidney function and its significance for the development of in-hospital complications in patients hospitalized with acute cardiovascular pathology infected with COVID-19.&#x0D; Methods. This prospective cohort single-center study included 139 patients with acute cardiovascular pathology diagnosed with COVID-19. Sixty-nine (49.6%) patients had acute coronary syndrome (47 with acute myocardial infarction (AMI), 33 (23.7%) patients had hypertension, 24 (17.3%) patients had acute decompensated heart failure, 9 (6.5%) patients had tachysystolic paroxysms of atrial fibrillation, 2 (1.4%) patients had an acute pulmonary embolism, and 2 (1.4%) patients had syncope. The mean age was 67.9±12.7 years, and 70 (50.4%) patients were male. Arterial hypertension was present in 87.1% of patients, diabetes mellitus in 20.9%, congestive heart failure in 30.9%, chronic obstructive pulmonary disease in 9.4%, AMI in 20.1%, and ischemic stroke in 9.4%.&#x0D; Results. The initial creatinine level was 110.7±66.1 μmol/l and eGFR (CKD-EPI) was 63.3±20.3 ml/min/1.73m2 (eGFR&lt;60 ml/min/1.73m2 was diagnosed in 46.0% of the patients). The patients with eGFR&lt;60 ml/min/1.73m2 were older, more often female, frequently had a history of atrial fibrillation, had lower hemoglobin and blood pressure on admission, a greater number of complications (need for noninvasive ventilation, inotropic therapy), and higher in-hospital mortality (25.0% vs. 5.3 %, p=0.002). Acute kidney injury, which was evaluated according to KDIGO criteria (increase in creatinine level ≥ 26.5 μmol/l within 48 hours or ≥ 1.5 times within 7 days) was observed in 21 (15.4%) patients (12.0% in patients with eGFR≥60 ml/min/1.73m2 and 18.8% with eGFR&lt;60 ml/min/1.73m2, p&lt;0.05).&#x0D; These patients did not differ significantly in basic clinical and anamnestic data from patients without AKI but had lower spO2 on admission (86.9±11.2% vs. 93.4±5.0%, p=0.016). Patients with AKI had a significantly higher number of in-hospital complications: acute hypoxic delirium (47.6% vs. 8.7%, p=0.003), venous thromboembolism (14.3% vs. 0.9%, p=0.070), death from all causes (47.6% vs. 7.0%, p=0.002) and more often required organ supportive therapy: non-invasive/invasive pulmonary ventilation (52.4% vs. 11.3%, p&lt;0.001), inotropic therapy (57.1% versus 5.2%, p&lt;0.001). Using the simplified criterion of AKI, the category of patients at high risk for hospital complications and death could also be distinguished (37.9% vs. 8.2%, p=0.004). Vaccination against COVID-19 (at least 2 weeks before hospitalization prevented the development of AKI (16.5% vs. 5.0%, p=0.046) and tended to prevent in-hospital mortality (15.7% vs. 5.0%, p=0.076).&#x0D; Conclusions. Renal dysfunction in patients with acute cardiovascular pathology infected with COVID-19 is associated with in-hospital complications and can be prevented by prophylactic vaccination.

Metabolic Syndrome and Its Components are Associated with In-Hospital Complications after Thoracic Endovascular Aortic Repair for Acute Type B Aortic Dissection

This study aimed to explore whether and to what extent metabolic syndrome (MetS) and its components are associated with in-hospital complications in patients with acute type B aortic dissection after thoracic endovascular aortic repair (TEVAR). We retrospectively enrolled 684 patients who had undergone TEVAR. Demographic and clinical data were collected and subgroup analysis, mixed-model regression analysis, scoring systems, and receiver operating characteristic (ROC) curve analyses were performed. Overall, 684 inpatients were assigned to the poor outcome (n=90) or no complications (n=594) group. Compared to the no complications group, the poor outcome group had a higher incidence of MetS (44 [48.9%] vs. 120 [20.2%], P<0.05). In the subgroup analysis, in-hospital complications were present in 3.1%, 6.6%, 11.9%, 20.7%, 40.0%, and 62.5% of patients in the 6 groups who met the 0, 1, 2, 3, 4, and 5 MetS diagnostic criteria, respectively. On multivariable logistic regression, hypertension (odds ratio [OR]: 2.680; 95% confidence interval [CI]: 1.571-4.570), type 2 diabetes (OR: 2.135; 95% CI: 1.192-3.824), quartiles of body mass index (OR: 1.801; 95% CI: 1.415-2.291), high-density lipoprotein cholesterol (OR: 0.763; 95% CI: 0.611-0.953), and systolic blood pressure (OR: 1.894; 95% CI: 1.486-2.413) were independent factors for in-hospital complications after adjustment for other risk factors. After adjusting for potential confounding factors, MetS was an independent risk factor for in-hospital complications. We established a scoring system for each component and the area under the ROC curve was 0.664 (95% CI: 0.618-0.710) in all patients, 0.672 (95% CI: 0.595-0.749) in patients with MetS, and 0.610 (95% CI: 0.552-0.667) in patients without MetS, as determined by ROC analysis. MetS, especially the blood pressure component, confers a greater risk of in-hospital complications in patients with acute type B aortic dissection after TEVAR.

Analysis of in-hospital complications in patients with acute cardiovascular pathology and co-infection with COVID-19: a registry of one center

The aim – to analyze in-hospital mortality in pts with acute cardiovascular pathology (ACP) and a co-infection with COVID-19.Materials and methods. 139 pts with ACP who were diagnosed with COVID-19 were examined. 69 (49.6 %) pts had ACS (47 pts with AMI), 33 (23.7 %) pts – hypertensive urgency, 24 (17.3 %) pts – ADHF, 9 (6.5 %) pts – tachysystolic paroxysm of atrial fibrillation, 2 (1.4 %) pts – acute pulmonary embolism, and 2 (1.4 %) pts – syncope. The average age was 67.9±12.7 y.o., 70 (50.4 %) pts were male. Concomitant arterial hypertension was found in 87.1 %, DM – 20.9 %, CHF – 30.9 %, COPD – 9.4 % of pts, history of AMI – 20.1 % and ischemic stroke – 9.4 % of pts. In 79 (56.8 %) pts COVID-19 was diagnosed and laboratory confirmed before hospitalization (hospitalized in 5.3±3.6 days after symptoms onset). 31 (22.3 %) pts were diagnosed with COVID-19 upon admission, and 29 (20.9 %) – during their stay in the hospital. 20 (15.6 %) pts were vaccinated against COVID-19. The initial SpO2 level was 91.6±10.3 %, while more than half of pts (53.2 %) had SpO2 &lt; 95 % and almost every fourth (23.2 %) patient had SpO2 &lt; 90 %.Results and discussion. During the hospital period, 20 (14.4 %) pts died. The mortality rate was 28.0 % in pts with ADHF, 19.1 % in pts with AMI and significantly less in pts hospitalized for unstable angina, hypertensive urgency or atrial fibrillation – 5.2 % (p&lt;0.05 in comparison with pts with AMI or ADHF). The main cause of death was the development of cardiopulmonary failure – 14 (70.0 %) pts. 4 (20.0 %) pts died from AMI complications, 1 – from pulmonary embolism and 1 – from acute ischemic stroke. Two critical periods of in-hospital mortality can be distinguished: 1 – the first two days of hospitalization (mainly complications of acute cardiovascular pathology and thrombotic events); 2 – from 7 to 10 days after hospitalization (development of multiple organ failure due to hypoxia and heart failure progression). The mortality rate of patients with ACP and COVID-19 was significantly higher than that of simultaneously hospitalized patients without comorbid respiratory infection (14.4 % vs. 6.4 %, p=0.012) and patients who were hospitalized before the pandemic (14.4 % vs. 2.9 %, p&lt;0.001). Vaccinated patients were significantly less likely to develop acute kidney injury, acute hypoxic delirium, had higher average blood SpO2, and less often required non-invasive ventilation. Only 1 vaccinated patient died from the development of cardiogenic shock against the background of anterior AMI and multivessel coronary artery disease (mortality – 15.7 % in unvaccinated pts vs 5.0 % in vaccinated, p=0.076).Conclusions. Co-infection with COVID-19 worsens treatment outcomes and in-hospital mortality of patients with ACP. Vaccination significantly reduces the likelihood of complications and tends to reduce mortality.

Risk Factors and Hospital Outcomes of Acute Kidney Injury in Patients Operated on for an acquired Valvular Heart Disease.

Aim To determine predictors of acute kidney injury (AKI) related with surgeries for correction of acquired valvular heart disease (HD) and to evaluate the incidence of in-hospital complications in patients with postoperative AKI.Material and methods This study included 62 patients after surgery for correction of acquired valvular HD (mean age, 61±10.9 years) with a disease duration of 11±5.3 years. NYHA functional class (FC) 1 chronic heart failure (CHF) was observed in 1.6 % of patients, FC 2 in 64.5 %, and FC 3 in 33.9 %.17.7% of patients had chronic kidney disease (CKD). Coronary lesions of ≥50 % of vascular lumen were detected in 27.4 % of patients. Surgical correction of mitral valvular disease was performed in 32 cases, aortic valvular disease in 36 cases, tricuspid valvular disease in 8 cases, and combined operations for correction of valvular disease and coronary bypass in 8 cases. Creatinine concentrations were measured according to the Jaffe method; glomerular filtration rate (GFR) was estimated with the CKD-EPI equation. AKI was diagnosed based on KDIGO (2012) criteria.Results The AKI incidence related with surgeries for correction of valvular HD was 16.1 % (8.1 % of patients had stage 1 AKI, 3.2 % had stage 2 AKI, and 4.8 % had stage 3 AKI), and 3.2% required kidney replacement therapy. AKI was associated with the presence of CKD at baseline (р=0.044), development of hemopericardium requiring drainage (р=0.012), more pronounced coronary lesions (in the AKI group: stenoses from 50 to 70 % in 20% of patients, from 70 to 90 % in 30 % of patients, and ≥90 % in 0 %; without AKI: from 50 to 70 % in 13.4 % of patients, from 70 to 90 % in 3.8 %, and ≥90 % in 5.8 % of patients, respectively; р=0.032). Probability of postoperative AKI significantly increased with the development of hemopericardium requiring drainage. Patients with postoperative AKI compared to persons without AKI had higher mortality (20 % and 0 %; р=0.001), greater incidence of decompensated CHF (40 and 9.6 %; р=0.012) and hemopericardium requiring drainage (30 and 1.9 %; р=0.012).Conclusion The development of postoperative AKI is associated with CKD at baseline, more pronounced coronary injury, and hemopericardium requiring drainage.

Cardiovascular parameters on computed tomography are independently associated with in-hospital complications and outcomes in level-1 trauma patients

BackgroundIn-hospital complications after trauma may result in prolonged stays, higher costs, and adverse functional outcomes. Among reported risk factors for complications are pre-existing cardiopulmonary comorbidities. Objective and quick evaluation of cardiovascular risk would be beneficial for risk assessment in trauma patients. Studies in non-trauma patients suggested an independent association between cardiovascular abnormalities visible on routine computed tomography (CT) imaging and outcomes. However, whether this applies to trauma patients is unknown.PurposeTo assess the association between cardiopulmonary abnormalities visible on routine CT images and the development of in-hospital complications in patients in a level-1 trauma center.MethodsAll trauma patients aged 16 years or older with CT imaging of the abdomen, thorax, or spine and admitted to the UMC Utrecht in 2017 were included. Patients with an active infection upon admission or severe neurological trauma were excluded. Routine trauma CT images were analyzed for visible abnormalities: pulmonary emphysema, coronary artery calcifications, and abdominal aorta calcification severity. Drug-treated complications were scored. The discharge condition was measured on the Glasgow Outcome Scale.ResultsIn total, 433 patients (median age 50 years, 67% male, 89% ASA 1–2) were analyzed. Median Injury Severity Score and Glasgow Coma Scale score were 9 and 15, respectively. Seventy-six patients suffered from at least one complication, mostly pneumonia (n = 39, 9%) or delirium (n = 19, 4%). Left main coronary artery calcification was independently associated with the development of any complication (OR 3.9, 95% CI 1.7–8.9). An increasing number of calcified coronary arteries showed a trend toward an association with complications (p = 0.07) and was significantly associated with an adverse discharge condition (p = 0.02). Pulmonary emphysema and aortic calcifications were not associated with complications.ConclusionCoronary artery calcification, visible on routine CT imaging, is independently associated with in-hospital complications and an adverse discharge condition in level-1 trauma patients. The findings of this study may help to identify trauma patients quickly and objectively at risk for complications in an early stage without performing additional diagnostics or interventions.

The Short Outcomes and In-Hospital Complications in Patients with STEMI Revascularized with Primary PCI

Context: Primary percutaneous coronary intervention (PCI) is the most effective reperfusion therapy with low complication rate in comparison to thrombolysis. Aims: We aimed to study the short-term outcomes of primary PCI at a large tertiary care center in India. Settings and Design: A prospective cohort of patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI was enrolled between December 2015 and November 2016. Subjects and Methods: The demographic profile, risk factors, clinical characteristics, inhospital complications, and outcomes at 30 days were assessed. The primary outcome was a composite of death, reinfarction, and repeat revascularization. Acute left ventricular failure (LVF), complete heart block (CHB) or bradyarrhythmia, ventricular tachycardia (VT) or ventricular fibrillation, stroke, and major thrombolysis in myocardial infarction bleeding were the inhospital complications that were considered the secondary outcomes. Results: A total of 237 STEMI patients with primary PCI were enrolled, accounting for 7.5% of all PCI procedures performed during this period. The mean age was 55.4 ± 11.9 years, and 86.5% were male. The mean window period was 5.1 ± 3.18 h, and the mean door-to-balloon time was 58.4 ± 11.5 min. Prior to PCI, the most often administered antiplatelets were clopidogrel in 54.4% of patients and prasugrel in 55.6%. The aspiration thrombectomy was done in 70.8% of patients. Predilatation with balloon was required in 41.8% of patients. Drug-eluting stents were implanted in 98.3% of patients. The primary outcome was found in 3.3% of patients (deaths – 2.9% and reinfarction – 0.4%) and the secondary outcomes were observed in 13%. The common inhospital complication was CHB or bradyarrhythmia in 5.0% followed by acute LVF in 4.6% and then VT in 2.1%. Conclusions: The primary outcome rate is as good as reported in developed Western countries in contemporary treatment practices of STEMI. CHB and acute LVF were the major inhospital complications among patients of STEMI treated with primary PCI.

The Influence of Renal Function on In-Hospital Complications in Patients with ST-Elevation Myocardial Infarction

Abstract Objective The goal of this study was to examine in-hospital complications in patients with acute ST-elevation myocardial infarction with a different renal function. Methods 351 patients were included in the study. Percutaneous coronary intervention was performed on all patients. 116 had a glomerular filtration rate &lt; 60 ml/min/1.73 m2 (Group 1), 120 ≥ 60 ml/min/1.73 m2 and &lt; 90 ml/min/1.73 m2 (Group 2) and 115 ≥ 90 ml/min/1.73 m2 (Group 3). Other parameters in the groups were comparable. The composite rate of acute pulmonary oedema and cardiogenic shock, in-hospital pneumonia, pulseless ventricular tachycardia or ventricular fibrillation, new-onset atrial fibrillation or atrial flutter, and in-hospital death were all compared among study groups. Results Mean glomerular filtration rate in Group 1 was 48.2±10.4; in Group 2, 74.7±8.7; and in Group 3, 104.1±14.6 (p &lt; 0.001). The incidence of atrial fibrillation or atrial flutter was higher in Group 1 than in Groups 2 and 3: 12.1%, 5.8%, and 3.5%, respectively (p &lt; 0.05). Group 3 had significantly lower rates of acute pulmonary oedema and cardiogenic shock than Groups 1 and 2: 10.3%, 5.8%, and 0.9%, respectively (p &lt; 0.05). There was also a significant difference between groups when comparing the rate of in-hospital pneumonia: Group 1 had reasonably higher rates of in-hospital pneumonia than Group 2 and Group 3: 13.8%, 6.7%, and 4.3% (p &lt; 0.05), respectively. The authors discovered no significant differences in additional complications: pulseless ventricular tachycardia or ventricular fibrillation occurred in 2.6%, 3.3%, and 0.9%, respectively (p &gt; 0.05). in-hospital death was 3.4% in Group 1; 0.8% in Group 2: and 0 in Group 3, (p &gt; 0.05). Conclusion Patients with lower glomerular filtration rate were more likely to develop in-hospital acute pulmonary oedema and cardiogenic shock, pneumonia, and new-onset atrial fibrillation or atrial flutter in ST-elevation myocardial infarction.

New model predicts in-hospital complications in myocardial infarction.

INTRODUCTION AND OBJECTIVES: Ischemic cardiopathy constitutes the leading cause of death worldwide. Our aim was to evaluate the prognostic capacity of the leukoglycemic index as well as to create a predictive model of in-hospital complications in patients with ST elevation myocardial infarction. MATERIALS AND METHODS: This was a multicentral and cohort study, which included patients inserted in the Cuban Registry of acute myocardial infarction. The study investigated 900 patients with a validation population represented by 233 external subjects. In order to define the performance of the leukoglycemic index were evaluated the discrimination with the statistical C and the calibration by Hosmer – Lemeshow test. A model of logistic binary regression was employed in order to define the predictive factors. RESULTS: Optimal cut point of the leukoglycemic index to predict in-hospital complications was 1188 (sensibility 60%; specificity 61.6%; area under the curve 0.623; p < 0.001). In-hospital complications were significantly higher in the group with the leukoglycemic index ≥ 1188; a higher value was significantly associated with a higher risk to develop an in-hospital complication [RR (IC 95%) = 2.4 (1.804–3.080); p<0.001]. The predictive model proposed is composed by the following factors: age ≥ 66 years, leukoglycemic index ≥ 1188, Killip-Kimball classification ≥ II and medical history of hypertension. This scale had a good discrimination in both, the training and the validation population. CONCLUSION: The leukoglycemic index possesses a low performance when used to assess the risks for in hospital complications in patients with ST elevation myocardial infarction. The new predictive model has a good performance, which can be applied to estimate risk of in-hospital complications. This model would be able to contribute to the health systems of developing countries without additional cost; it enables prediction of the patients having a higher risk of complications and a negative outcome during the hospitable admission.

Impact of Delayed Pain to Needle and Variable Door to Needle Time On In-Hospital Complications in Patients With ST-Elevation Myocardial Infarction Who Underwent Thrombolysis: A Single-Center Experience.

BackgroundMyocardial infarction is a life-threatening event, and timely intervention is essential to improve patient outcomes and mortality. Previous studies have shown that the time to thrombolysis should be less than 30 minutes of the patient’s arrival at the emergency room. Pain-to-needle time is a time from onset of chest pain to the initiation of thrombolysis, and door-to-needle time is a time between arrival to the emergency room to initiation of thrombolytic treatment. Ideally, the target for door-to-needle time should be less than 30 minutes; however, it is unclear if the door-to-needle time has a significant impact on patients presenting later than three hours from the onset of pain. As many of the previous studies were conducted in first-world countries, with established emergency medical services (EMS) systems and pre-hospital ST-elevation myocardial infarction (STEMI) triages and protocols, the data is not completely generalizable to developing countries. We, therefore, looked for the impact of the shorter and longer door-to-needle times on patient outcomes who presented to the emergency room (ER) with delayed pain-to-needle times (more than three hours of pain onset). ObjectiveTo determine the impact of delayed pain-to-needle time (PNT) with variable door-to-needle time (DNT) on in-hospital complications (post-infarct angina, heart failure, left ventricular dysfunction, and death) in patients with ST-elevation myocardial infarction (STEMI) who underwent thrombolysis.Methods and resultsA total of 300 STEMI patients who underwent thrombolysis within 12 hours of symptoms onset were included, which were divided into two groups based on PNT. These groups were further divided into subgroups based on DNT. The primary outcome was in-hospital complications between the two groups and between subgroups within each group. The pain-to-needle time was ≤3 hours in 73 (24.3%) patients and >3 hours in 227 (75.7%) patients. In-hospital complications were higher in group II with PNT >3 hours (p <0.05). On subgroup analysis, in-hospital complications were higher with longer door-to-needle time in group II (p<0.05); however, there was no difference in complications among group I.ConclusionOur study is consistent with the fact that shorter door-to-needle time, even in patients with delayed PNT (>3 hours), has a significant impact on in-hospital complications with no difference in mortality.
