Serum lactate dehydrogenase and its isoenzymes as predictors of clinical outcomes in acute exacerbation of chronic obstructive pulmonary disease: a retrospective analysis of a hospitalized cohort.

We aimed to test the association between serum lactate dehydrogenase (LDH) and its isoenzymes and treatment outcomes during hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Thirty-eight AECOPD patients were recruited from a tertiary hospital from December 2017 to June 2018. Serum LDH and LDH isoenzymes were measured on venous blood collected at admission. Treatment outcomes included duration of hospital stay, initiation of non-invasive (NIV) or mechanical ventilation, initiation of antipseudomonal antibiotics, change in empirical antibiotic treatment, need for intravenous corticosteroids or methylxanthines, and percentage of change in C-reactive protein from admission to the third day. Multivariate linear and binary logistic regression analyses were used to test the study's objectives. We found that, after adjusting for age, gender, comorbidities, COPD severity, level of hypoxemia, and inflammation markers, each 10 U/L increase in serum LDH was associated with prolongation of the hospital stay by 0.25 (0.03, 0.46) days, 42% higher odds (odds ratio [OR] 1.42 [1.00, 2.03]) for need of NIV, and 25% higher odds (OR 1.25 [1.04, 1.49]) for initiation of antipseudomonal treatment. LDH1 and LDH2 were the LDH isoenzymes that mainly drove these relationships. LDH release in the context of an AECOPD could originate from lung, muscle, or heart tissue damage due to airway inflammation, respiratory muscle recruitment, and myocardial stress. Myocardial injury and aerobic adaptation in respiratory muscles may explain the predominance of LDH1 and LDH2 isoenzymes in these associations.

Invasive pulmonary aspergillosis among intubated patients with SARS-CoV-2 or influenza pneumonia: a European multicenter comparative cohort study.

BACKGROUND: Recent multicenter studies identified COVID-19 as a risk factor for invasive pulmonary aspergillosis (IPA). However, no large multicenter study has compared the incidence of IPA between COVID-19 and influenza patients. OBJECTIVES: To determine the incidence of putative IPA in critically ill SARS-CoV-2 patients, compared with influenza patients. METHODS: This study was a planned ancillary analysis of the coVAPid multicenter retrospective European cohort. Consecutive adult patients requiring invasive mechanical ventilation for > 48 h for SARS-CoV-2 pneumonia or influenza pneumonia were included. The 28-day cumulative incidence of putative IPA, based on Blot definition, was the primary outcome. IPA incidence was estimated using the Kalbfleisch and Prentice method, considering extubation (dead or alive) within 28 days as competing event. RESULTS: A total of 1047 patients were included (566 in the SARS-CoV-2 group and 481 in the influenza group). The incidence of putative IPA was lower in SARS-CoV-2 pneumonia group (14, 2.5%) than in influenza pneumonia group (29, 6%), adjusted cause-specific hazard ratio (cHR) 3.29 (95% CI 1.53-7.02, p = 0.0006). When putative IPA and Aspergillus respiratory tract colonization were combined, the incidence was also significantly lower in the SARS-CoV-2 group, as compared to influenza group (4.1% vs. 10.2%), adjusted cHR 3.21 (95% CI 1.88-5.46, p < 0.0001). In the whole study population, putative IPA was associated with significant increase in 28-day mortality rate, and length of ICU stay, compared with colonized patients, or those with no IPA or Aspergillus colonization. CONCLUSIONS: Overall, the incidence of putative IPA was low. Its incidence was significantly lower in patients with SARS-CoV-2 pneumonia than in those with influenza pneumonia.

Early Bacterial Identification among Intubated Patients with COVID-19 or Influenza Pneumonia: A European Multicenter Comparative Clinical Trial.

Rationale: Early empirical antimicrobial treatment is frequently prescribed to critically ill patients with coronavirus disease (COVID-19) based on Surviving Sepsis Campaign guidelines.Objectives: We aimed to determine the prevalence of early bacterial identification in intubated patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia, as compared with influenza pneumonia, and to characterize its microbiology and impact on outcomes.Methods: A multicenter retrospective European cohort was performed in 36 ICUs. All adult patients receiving invasive mechanical ventilation >48 hours were eligible if they had SARS-CoV-2 or influenza pneumonia at ICU admission. Bacterial identification was defined by a positive bacterial culture within 48 hours after intubation in endotracheal aspirates, BAL, blood cultures, or a positive pneumococcal or legionella urinary antigen test.Measurements and Main Results: A total of 1,050 patients were included (568 in SARS-CoV-2 and 482 in influenza groups). The prevalence of bacterial identification was significantly lower in patients with SARS-CoV-2 pneumonia compared with patients with influenza pneumonia (9.7 vs. 33.6%; unadjusted odds ratio, 0.21; 95% confidence interval [CI], 0.15-0.30; adjusted odds ratio, 0.23; 95% CI, 0.16-0.33; P < 0.0001). Gram-positive cocci were responsible for 58% and 72% of coinfection in patients with SARS-CoV-2 and influenza pneumonia, respectively. Bacterial identification was associated with increased adjusted hazard ratio for 28-day mortality in patients with SARS-CoV-2 pneumonia (1.57; 95% CI, 1.01-2.44; P = 0.043). However, no significant difference was found in the heterogeneity of outcomes related to bacterial identification between the two study groups, suggesting that the impact of coinfection on mortality was not different between patients with SARS-CoV-2 and influenza.Conclusions: Bacterial identification within 48 hours after intubation is significantly less frequent in patients with SARS-CoV-2 pneumonia than patients with influenza pneumonia.Clinical trial registered with www.clinicaltrials.gov (NCT04359693).

Relationship between ventilator-associated pneumonia and mortality in COVID-19 patients: a planned ancillary analysis of the coVAPid cohort.

BACKGROUND: Patients with SARS-CoV-2 infection are at higher risk for ventilator-associated pneumonia (VAP). No study has evaluated the relationship between VAP and mortality in this population, or compared this relationship between SARS-CoV-2 patients and other populations. The main objective of our study was to determine the relationship between VAP and mortality in SARS-CoV-2 patients. METHODS: Planned ancillary analysis of a multicenter retrospective European cohort. VAP was diagnosed using clinical, radiological and quantitative microbiological criteria. Univariable and multivariable marginal Cox's regression models, with cause-specific hazard for duration of mechanical ventilation and ICU stay, were used to compare outcomes between study groups. Extubation, and ICU discharge alive were considered as events of interest, and mortality as competing event. FINDINGS: Of 1576 included patients, 568 were SARS-CoV-2 pneumonia, 482 influenza pneumonia, and 526 no evidence of viral infection at ICU admission. VAP was associated with significantly higher risk for 28-day mortality in SARS-CoV-2 (adjusted HR 1.70 (95% CI 1.16-2.47), p = 0.006), and influenza groups (1.75 (1.03-3.02), p = 0.045), but not in the no viral infection group (1.07 (0.64-1.78), p = 0.79). VAP was associated with significantly longer duration of mechanical ventilation in the SARS-CoV-2 group, but not in the influenza or no viral infection groups. VAP was associated with significantly longer duration of ICU stay in the 3 study groups. No significant difference was found in heterogeneity of outcomes related to VAP between the 3 groups, suggesting that the impact of VAP on mortality was not different between study groups. INTERPRETATION: VAP was associated with significantly increased 28-day mortality rate in SARS-CoV-2 patients. However, SARS-CoV-2 pneumonia, as compared to influenza pneumonia or no viral infection, did not significantly modify the relationship between VAP and 28-day mortality. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov, number NCT04359693.

The role of antimicrobial resistance on long-term mortality and quality of life in critically ill patients: a prospective longitudinal 2-year study.

BACKGROUND: In the recent era, antimicrobial resistance has been identified as one of the most important threats to human health worldwide. The rapid emergence of antibiotic-resistant pathogens (ABRP) in the modern intensive care unit (ICU) also represents a "nightmare scenario" with unknown clinical consequences. In the Greek ICU, in particular, gram negative ABRPs are now considered endemic. However, the possible longitudinal impact of ABRPs on long-term outcomes of ICU patients has not yet been determined. METHODS: In this two-year (January 2014-December 2015) single-centre observational longitudinal study, 351 non-neurocritical ICU patients ≥ 18 year-old were enrolled. Patients' demographic, clinical and outcome data were prospectively collected. Quality-adjusted life years (QALY) were calculated at 6, 12, 18 and 24 months after ICU admission. RESULTS: Fifty-eight patients developed infections due to ABRP (ABRP group), 57 due to non-ABRP (non-ABRP group), and 236 demonstrated no infection (no-infection group) while in ICU. Multiple regression analysis revealed that multiple organ dysfunction syndrome score (OR: 0.676, 95%CI 0.584-0.782; P < 0.001) and continuous renal replacement therapy (OR: 4.453, 95%CI 1.805-10.982; P = 0.001) were the only independent determinants for ABRP infections in ICU. Intra-ICU, 90-day and 2-year mortality was 27.9%, 52.4% and 61.5%, respectively. Compared to the non-ABRP and no-infection group, the ABRP group demonstrated increased intra-ICU, 90-day and 2-year mortality (P ≤ 0.022), worse 2-year survival rates in ICU patients overall and ICU survivor subset (Log-rank test, P ≤ 0.046), and poorer progress over time in 2-year QALY kinetics in ICU population overall, ICU survivor and 2-year survivor subgroups (P ≤ 0.013). ABRP group was further divided into multi-drug and extensively-drug resistant subgroups [MDR (n = 34) / XDR (n = 24), respectively]. Compared to MDR subgroup, the XDR subgroup demonstrated increased ICU, 90-day and 2-year mortality (P ≤ 0.031), but similar 90-day and 2-year QALYs (P ≥ 0.549). ABRP infections overall (HR = 1.778, 95% CI 1.166-2.711; P = 0.008), as well as XDR [HR = 1.889, 95% CI 1.075-3.320; P = 0.027) but not MDR pathogens, were independently associated with 2-year mortality, after adjusting for several covariates of critical illness. CONCLUSIONS: The present study may suggest a significant association between ABRP (especially XDR) infections in ICU and increased mortality and inability rates for a prolonged period post-discharge that requires further attention in larger-scale studies.

Ceftazidime-Avibactam To Treat Life-Threatening Infections by Carbapenem-Resistant Pathogens in Critically Ill Mechanically Ventilated Patients.

Data on the effectiveness of ceftazidime-avibactam (CAZ-AVI) in critically ill, mechanically ventilated patients are limited. The present retrospective observational cohort study, which was conducted in two general intensive care units (ICUs) in central Greece, compared critically ill, mechanically ventilated patients suffering from carbapenem-resistant Enterobacteriaceae (CRE) infections receiving CAZ-AVI to patients who received appropriate available antibiotic therapy. Clinical and microbiological outcomes and safety issues were evaluated. A secondary analysis in patients with bloodstream infections (BSIs) was conducted. Forty-one patients that received CAZ-AVI (the CAZ-AVI group) were compared to 36 patients that received antibiotics other than CAZ-AVI (the control group). There was a significant improvement in the Sequential Organ Failure Assessment (SOFA) score on days 4 and 10 in the CAZ-AVI group compared to that in the control group (P = 0.006, and P = 0.003, respectively). Microbiological eradication was accomplished in 33/35 (94.3%) patients in the CAZ-AVI group and 21/31 (67.7%) patients in the control group (P = 0.021), and clinical cure was observed in 33/41 (80.5%) versus 19/36 (52.8%) patients (P = 0.010), respectively. The results were similar in the BSI subgroups for both outcomes (P = 0.038 and P = 0.014, respectively). The 28-day survival was 85.4% in the CAZ-AVI group and 61.1% in the control group (log-rank test = 0.035), while there were 2 and 12 relapses in the CAZ-AVI and control groups, respectively (P = 0.042). A CAZ-AVI-containing regime was an independent predictor of survival and clinical cure (odds ratio [OR] = 5.575 and P = 0.012 and OR = 5.125 and P = 0.004, respectively), as was illness severity. No significant side effects were recorded. In conclusion, a CAZ-AVI-containing regime was more effective than other available antibiotic agents for the treatment of CRE infections in the high-risk, mechanically ventilated ICU population evaluated.

Intra-Abdominal Hypertension is a Risk Factor for Increased VAP Incidence: A Prospective Cohort Study in the ICU of a Tertiary Hospital.

BACKGROUND: Ventilator-associated pneumonia (VAP) might be increased in cases with intra-abdominal hypertension (IAH). However, despite animal experimentation and physiological studies on humans in favor of this hypothesis, there is no definitive clinical data that IAH is associated with VAP. We therefore aimed to study whether IAH is a risk factor for increased incidence of VAP in critical care patients. This 1-center prospective observational cohort study was conducted in the intensive care unit of the University Hospital of Larissa, Greece, during 2013 to 2015. Consecutive patients were recruited if they presented risk factors for IAH at admission and were evaluated systematically for IAH and VAP for a 28-day period. RESULTS: Forty-five (36.6%) of 123 patients presented IAH and 45 (36.6%) presented VAP; 24 patients presented VAP following IAH. Cox regression analysis showed that VAP was independently associated with IAH (1.06 [1.01-1.11]; P = .053), while there was an indication for an independent association between VAP and abdominal surgery (1.62 [0.87-3.03]; P = .11] and chronic obstructive pulmonary disease (1.79 [0.96-3.37]; P = .06). CONCLUSIONS: Intra-abdominal hypertension is an independent risk factor for increased VAP incidence in critically ill patients who present risk factors for IAH at admission to the ICU.

Malignant mesothelioma cells secrete natriuretic peptides: Data and diagnostic clinical implications.

BACKGROUND AND OBJECTIVE: Mesothelial cells and cardiomyocytes have shared embryonic mesodermal origin. Cardiomyocytes release BNP under stretch. We searched whether malignant mesothelioma cells also secrete BNP and if so, this has a meaningful impact. METHODS: Part I: Prospectively, patients with pleural lesions on CT having malignant mesothelioma effusions (MME, n = 13) were compared to patients with malignant effusions with pleural lesions (MEa, n = 14). Age-matched patients with ME without pleural lesions (MEb, n = 16) and non-malignant effusions (NME, n = 25) were analysed. Part II: Retrospectively, samples from patients with mesothelioma (n = 14), lung cancer (n = 8) or heart failure (n = 9) were used. BNP was measured in pleural fluid and blood/plasma. Part III: BNP was assessed in the culture supernatants of benign (MeT-5A) and malignant mesothelioma cell lines (M14K-epithelioid, MSTO-biphasic and ZL34-sarcomatoid) (n = 10 per cell line in three different biological replicates). RESULTS: In vitro, BNP concentration was significantly higher in the supernatant of all malignant cell lines than benign ones (P < 0.01), denoting BNP's production from the former. The pleural fluid to blood BNP ratio in MME was extremely high in Part I and Part II subjects (28.3 ± 12.1 and 25.9 ± 8.6, respectively) versus 1.1 ± 0.3 and 0.4 ± 0.1 in Part I ME and NME, respectively (P < 0.0001), and 0.8 ± 0.1 and 0.4 ± 0.1 in Part II ME and NME, respectively (P < 0.0001). BNP ratio ≥2.11 in Part I had 92% sensitivity and 94.5% specificity for MME (P < 0.0001). CONCLUSION: BNP is secreted from malignant mesothelial cells. In clinical practice, the pleural fluid to blood BNP ratio can help in the diagnosis of malignant mesothelioma.

Changes in dynamic lung mechanics after lung volume reduction coil treatment of severe emphysema.

We assessed the relationships between changes in lung compliance, lung volumes and dynamic hyperinflation in patients with emphysema who underwent bronchoscopic treatment with nitinol coils (coil treatment) (n=11) or received usual care (UC) (n=11). Compared with UC, coil treatment resulted in decreased dynamic lung compliance (CLdyn) (p=0.03) and increased endurance time (p=0.010). The change in CLdyn was associated with significant improvement in FEV1 and FVC, with reduction in residual volume and intrinsic positive end-expiratory pressure, and with increased inspiratory capacity at rest/and at exercise. The increase in end-expiratory lung volume (EELV) during exercise (EELVdyn-ch=EELVisotime EELVrest) demonstrated significant attenuation after coil treatment (p=0.02).

Publisher Correction: Exposure to Stress-Dose Steroids and Lethal Septic Shock After In-Hospital Cardiac Arrest: Individual Patient Data Reanalysis of Two Prior Randomized Clinical Trials that Evaluated the Vasopressin-Steroids-Epinephrine Combination Versus Epinephrine Alone.

The original version of this article unfortunately contained a mistake. In Table 2, the frequency of Septic Shock reported just below the frequency of "At least 1 Episode of VAP" actually corresponds to the First (and not the Second) Episode of VAP during the postresuscitation period.

Exposure to Stress-Dose Steroids and Lethal Septic Shock After In-Hospital Cardiac Arrest: Individual Patient Data Reanalysis of Two Prior Randomized Clinical Trials that Evaluated the Vasopressin-Steroids-Epinephrine Combination Versus Epinephrine Alone.

PURPOSE: Low-dose steroids may reduce the mortality of severely ill patients with septic shock. We sought to determine whether exposure to stress-dose steroids during and/or after cardiopulmonary resuscitation is associated with reduced risk of death due to postresuscitation septic shock. METHODS: We analyzed pooled, individual patient data from two prior, randomized clinical trials (RCTs). RCTs evaluated vasopressin, steroids, and epinephrine (VSE) during resuscitation and stress-dose steroids after resuscitation in vasopressor-requiring, in-hospital cardiac arrest. In the second RCT, 15 control group patients received open-label, stress-dose steroids. Patients with postresuscitation shock were assigned to a Steroids (n = 118) or No Steroids (n = 73) group according to an "as-treated" principle. We used cumulative incidence competing risks Cox regression to determine cause-specific hazard ratios (CSHRs) for pre-specified predictors of lethal septic shock (primary outcome). In sensitivity analyses, data were analyzed according to the intention-to-treat (ITT) principle (VSE group, n = 103; control group, n = 88). RESULTS: Lethal septic shock was less likely in Steroids versus No Steroids group, CSHR, 0.40, 95% confidence interval (CI), 0.20-0.82; p = 0.012. ITT analysis yielded similar results: VSE versus Control, CSHR, 0.44, 95% CI, 0.23-0.87; p = 0.019. Adjustment for significant, between-group baseline differences in composite cardiac arrest causes such as "hypotension and/or myocardial ischemia" did not appreciably affect the aforementioned CSHRs. CONCLUSIONS: In this reanalysis, exposure to stress-dose steroids (primarily in the context of a combined VSE intervention) was associated with lower risk of postresuscitation lethal septic shock.

The value of the identification of predisposing factors for post-traumatic amnesia in management of mild traumatic brain injury.

OBJECT: To identify the risk factors for post-traumatic amnesia (PTA) and to document the incidence of PTA after mild traumatic brain injuries. METHODS: This was a prospective study, affecting mild TBI (mTBI) (Glasgow Coma Scale 14-15) cases attending to the Emergency Department between January 2009 and April 2012 (40 months duration). Patients were divided into two groups (Group A: without PTA, and Group B: with PTA, and they were assessed according to the risk factors. RESULTS: A total of 1762 patients (males: 1002, 56.8%) were meeting study inclusion criteria [Group A: n = 1678 (83.8%), Group B: n = 84 (4.2%)]. Age, CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs, and skull base fractures), anticoagulation therapy and seizures were independent factors of PTA. There was no statistically significant correlation between PTA and sex, convexity fractures, stroke event, mechanism of mTBI (fall +/or beating), hypertension, coronary heart disease, chronic smokers and diabetes (p > 0.005). CONCLUSION: CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs and skull base fractures), age, seizures and anticoagulation/antiplatelet therapy, were independent factors of PTA and could be used as predictive factors after mTBI.

Colistin versus Colistin Combined with Ampicillin-Sulbactam for Multiresistant Acinetobacter baumannii Ventilator-associated Pneumonia Treatment: An Open-label Prospective Study.

BACKGROUND: Retrospective studies have reported good clinical success rates using colistin as monotherapy to treat Acinetobacter baumannii ventilator-associated pneumonia (VAP), comparable to that obtained with colistin combined with other antibiotics. However, inadequate penetration into the pulmonary parenchyma for colistin has been shown in animal models. AIM: The aim of the study was to study prospectively the outcome, measured as clinical response and survival, of intravenously administered colistin versus colistin combined with high-dose ampicillin-sulbactam in Intensive Care Unit (ICU) patients with multiresistant A. baumannii VAP. METHODS AND SUBJECTS: This prospective, open-label, randomized study included consecutive patients who developed microbiologically documented VAP due to A. baumannii with carbapenem-resistant strains but susceptible to colistin and ampicillin-sulbactam. Seventy-four patients were screened, but finally, 39 participants were enrolled and finished the study Patients received colistin (Group A - 19 patients) or colistin and ampicillin/sulbactam (Group B - 20 patients). The clinical response of VAP was assessed on day 4th to 5th of treatment (early response). If therapy was considered unsuccessful after this period, ampicillin/sulbactam was added in Group A or changed therapy in B. RESULTS: Early cure rates in Group A and B were 15.8% and 70%, respectively (P = 0.001). Multiple regression analysis revealed that combination treatment (odds ratio [OR]: 43.6, 95% confidence interval [CI]: 3.594-530.9) and Sequential Organ Failure Assessment score <8 (OR: 0.022, 95% CI: 0.001-0.43) were independently associated with favorable clinical response. APACHE II score ≤15 (OR: 0.049, 95% CI: 0.003-0.0942) and an early favorable response to treatment (OR: 244.4, 95% CI: 2.151-27850.9) were associated with survival and discharge from ICU. CONCLUSION: Combination therapy with colistin and a high dose of ampicillin/sulbactam was associated with a more favorable clinical response to VAP due to carbapenem-resistant A. baumannii than colistin monotherapy.

The impact of N-acetylcysteine and ascorbic acid in contrast-induced nephropathy in critical care patients: an open-label randomized controlled study.

BACKGROUND: The aim was to investigate whether the use of N-acetylcysteine and ascorbic acid reduce contrast-induced nephropathy incidence in critical care patients. METHODS: This was a one-center, two-arm, prospective, randomized, open-label, controlled trial in the Intensive Care Unit of the University Hospital of Larissa, Greece. Patients with stable renal function, who underwent non urgent contrast-enhanced computed tomography for diagnostic purposes, were included in the study. Patients in the treatment group (NacA, n = 60) received intravenously N-acetylcysteine (1200 mg) and ascorbic acid (2 g) dissolved separately in 100 ml of normal saline 2 hours before, and at 10 hours and 18 hours following the infusion of contrast agent, while control group patients (CG, n = 64) received only normal saline. All patients received additional hydration. Contrast-induced nephropathy was defined as relative increase by 25% of the baseline values of serum creatinine. RESULTS: Contrast-induced nephropathy in NacA and CG were 18.33% and 15.6%, respectively (p = 0.81). The percentage change median (interquartile range (IR)) of serum cystatin-C (mg/L) from baseline in patients who underwent contrast-induced tomography, were 37.23% (28.53) and 93.20% (46.90) in NacA and in CG, respectively (p = 0.03). The 8-isoprostane serum levels in NacA were significantly lower compared to CG at 2 hours (p = 0.012) and 24 hours (p = 0.006) following radiocontrast infusion. Multivariate analysis revealed that contrast-induced nephropathy was independently associated with a higher baseline ratio of serum urea/creatinine (odds ratio, 1.02; 95 CI%, 1.00-1.05) and with the use of nephrotoxic medications (odds ratio, 0.24; 95 CI%, 0.06-0.94). CONCLUSION: Intravenous administration of N-acetylcysteine and ascorbic acid failed to reduce contrast-induced nephropathy in critically ill patients who underwent contrast-enhanced computed tomography, despite a significant reduction of 8-isoprostane levels in treated patients.

Takotsubo cardiomyopathy: A known unknown foe of asthma.

INTRODUCTION: Patients with uncontrolled asthma are at a greater risk of asthma attacks requiring emergency room visits or hospital admissions. Takotsubo cardiomyopathy is potentially a significant complication in a course of status asthmaticus. CASE STUDY: We describe a 43-year-old female patient who presented with status asthmaticus that was further complicated with takotsubo cardiomyopathy. RESULTS: Recognizing apical ballooning syndrome is challenging in patients with a history of respiratory disease because the symptoms of the last entity may complicate the diagnostic approach. It is difficult to distinguish clinically apical ballooning syndrome from the acute airway exacerbation itself. Both asthma and takotsubo cardiomyopathy share the same clinical presentation with dyspnea and chest tightness. In our patient, the electrocardiographic abnormalities, the rapidly reversible distinctive characteristics of echocardiography, and the modest elevation of serum cardiac biomarkers levels, in combination with the presence of a stress trigger (severe asthma attack), strongly supported the diagnosis of broken heart syndrome. CONCLUSIONS: Clinicians should re-evaluate asthma management and be aware of the complications associated with asthma attacks such as stress-induced cardiomyopathy.

Post-partum hemorrhage complicated by reverse-Takotsubo cardiogenic shock; a novel therapeutic approach.

Takotsubo Cardiomyopathy (TTC) is a type of transient, yet severe left ventricular systolic dysfunction, rarely complicating extreme emotional stress ("primary" TTC) or critical medical/surgical illness ("secondary" TTC forms). Although usually reversible, TTC may result in cardiogenic shock with dismal prognosis. "Secondary" TTC forms are particularly in danger for this complication, bearing significantly worse short and long-term prognosis. Herein, we report a rare case of a life-threatening "secondary" TTC in a patient with post-cesarean section severe hemorrhage, and we point out that early co-administration of esmolol and levosimendan might be an effective and safe therapeutic approach in "reversing" TTC-induced cardiogenic shock, especially when invasive therapeutic strategies are practically unfeasible.
