Pediatric takotsubo cardiomyopathy: A review and insights from a National Multicentric Registry.

Takotsubo syndrome (TTS) in the pediatric population is an infrequent but relevant cause of morbidity and mortality, with limited studies addressing its clinical course and prognosis. We aimed to analyze the clinical features and prognosis of pediatric TTS in a nation-wide multicenter registry and considering the published literature. We included a total of 54 patients from 4 different hospitals in Spain, as well as pediatric TTS patients from the published literature. Comparisons between groups were performed in order to assess for statistically and clinically relevant prognostic differences between pediatric and adult population features. Patients with pediatric TTS are more commonly male and exhibit a higher prevalence of physical triggers. The left ventricular ejection fraction (LVEF) was significantly lower in the pediatric population (30.5 + 10.4 vs 36.9 + 16.9, p < 0.05), resulting in more than fivefold rates of cardiogenic shock on admission compared to the general adult TTS population (Killip IV 74.1% vs 10.5%, p < 0.001) with similar rates of death and recurrence between groups. TTS in the pediatric population presents a distinctive clinical profile, with higher prevalence of atypical symptoms and physical triggers, as well as higher rates of cardiogenic shock on admission and similar mortality and recurrence rates than those of the adult population. This study provides valuable insights into understanding pediatric TTS and underscores the necessity for further research in this age group.

Thalassaemia is paradoxically associated with a reduced risk of in-hospital complications and mortality in COVID-19: Data from an international registry.

Although numerous patient-specific co-factors have been shown to be associated with worse outcomes in COVID-19, the prognostic value of thalassaemic syndromes in COVID-19 patients remains poorly understood. We studied the outcomes of 137 COVID-19 patients with a history of transfusion-dependent thalassaemia (TDT) and transfusion independent thalassaemia (TIT) extracted from a large international cohort and compared them with the outcomes from a matched cohort of COVID-19 patients with no history of thalassaemia. The mean age of thalassaemia patients included in our study was 41 ± 16 years (48.9% male). Almost 81% of these patients suffered from TDT requiring blood transfusions on a regular basis. 38.7% of patients were blood group O. Cardiac iron overload was documented in 6.8% of study patients, whereas liver iron overload was documented in 35% of study patients. 40% of thalassaemia patients had a history of splenectomy. 27.7% of study patients required hospitalization due to COVID-19 infection. Amongst the hospitalized patients, one patient died (0.7%) and one patient required intubation. Continuous positive airway pressure (CPAP) was required in almost 5% of study patients. After adjustment for age-, sex- and other known risk factors (cardiac disease, kidney disease and pulmonary disease), the rate of in-hospital complications (supplemental oxygen use, admission to an intensive care unit for CPAP therapy or intubation) and all-cause mortality was significantly lower in the thalassaemia group compared to the matched cohort with no history of thalassaemia. Amongst thalassaemia patients in general, the TIT group exhibited a higher rate of hospitalization compared to the TDT group (p = 0.001). In addition, the rate of complications such as acute kidney injury and need for supplemental oxygen was significantly higher in the TIT group compared to the TDT group. In the multivariable logistic regression analysis, age and history of heart or kidney disease were all found to be independent risk factors for increased in-hospital, all-cause mortality, whereas the presence of thalassaemia (either TDT or TIT) was found to be independently associated with reduced all-cause mortality. The presence of thalassaemia in COVID-19 patients was independently associated with lower in-hospital, all-cause mortality and few in-hospital complications in our study. The pathophysiology of this is unclear and needs to be studied in vitro and in animal models.

Chronic Oral Anticoagulation Therapy and Prognosis of Patients Admitted to Hospital for COVID-19: Insights from the HOPE COVID-19 Registry.

Background: Most evidence regarding anticoagulation and COVID-19 refers to the hospitalization setting, but the role of oral anticoagulation (OAC) before hospital admission has not been well explored. We compared clinical outcomes and short-term prognosis between patients with and without prior OAC therapy who were hospitalized for COVID-19. Methods: Analysis of the whole cohort of the HOPE COVID-19 Registry which included patients discharged (deceased or alive) after hospital admission for COVID-19 in 9 countries. All-cause mortality was the primary endpoint. Study outcomes were compared after adjusting variables using propensity score matching (PSM) analyses. Results: 7698 patients were suitable for the present analysis (675 (8.8%) on OAC at admission: 427 (5.6%) on VKAs and 248 (3.2%) on DOACs). After PSM, 1276 patients were analyzed (638 with OAC; 638 without OAC), without significant differences regarding the risk of thromboembolic events (OR 1.11, 95% CI 0.59-2.08). The risk of clinically relevant bleeding (OR 3.04, 95% CI 1.92-4.83), as well as the risk of mortality (HR 1.22, 95% CI 1.01-1.47; log-rank p value = 0.041), was significantly increased in previous OAC users. Amongst patients on prior OAC only, there were no differences in the risk of clinically relevant bleeding, thromboembolic events, or mortality when comparing previous VKA or DOAC users, after PSM. Conclusion: Hospitalized COVID-19 patients on prior OAC therapy had a higher risk of mortality and worse clinical outcomes compared to patients without prior OAC therapy, even after adjusting for comorbidities using a PSM. There were no differences in clinical outcomes in patients previously taking VKAs or DOACs. This trial is registered with NCT04334291/EUPAS34399.

Score2: A New Updated Algorithm to Predict Cardiovascular Disease Risk in Europe.

The recently published guidelines of the European Society of Cardiology for the prevention of cardiovascular diseases presented in August 2021 at the virtual European Society of Cardiology congress recommend the use of the SCORE2 risk index instead of the classic SCORE risk index to calculate the cardiovascular risk (specifically, ten-year fatal and nonfatal risk) in a healthy population under the age of 70 years, with a level of evidence IB. This new risk index was developed with the collaboration of about 200 investigators, including 45 cohorts in 13 countries with 700,000 participants, and covers the known risk factors for heart and circulatory diseases such as age, sex, lipid levels, blood pressure, and smoking. In addition, it divides the countries into four groups of risk and uses a competing risk model, adjusting the risk for the probability of having another event, which enables better estimation of the risk of fatal and nonfatal events in a younger population (40-69 years).

Renin-angiotensin system inhibitors effect before and during hospitalization in COVID-19 outcomes: Final analysis of the international HOPE COVID-19 (Health Outcome Predictive Evaluation for COVID-19) registry.

BACKGROUND: The use of Renin-Angiotensin system inhibitors (RASi) in patients with coronavirus disease 2019 (COVID-19) has been questioned because both share a target receptor site. METHODS: HOPE-COVID-19 (NCT04334291) is an international investigator-initiated registry. Patients are eligible when discharged after an in-hospital stay with COVID-19, dead or alive. Here, we analyze the impact of previous and continued in-hospital treatment with RASi in all-cause mortality and the development of in-stay complications. RESULTS: We included 6503 patients, over 18 years, from Spain and Italy with data on their RASi status. Of those, 36.8% were receiving any RASi before admission. RASi patients were older, more frequently male, with more comorbidities and frailer. Their probability of death and ICU admission was higher. However, after adjustment, these differences disappeared. Regarding RASi in-hospital use, those who continued the treatment were younger, with balanced comorbidities but with less severe COVID19. Raw mortality and secondary events were less frequent in RASi. After adjustment, patients receiving RASi still presented significantly better outcomes, with less mortality, ICU admissions, respiratory insufficiency, need for mechanical ventilation or prone, sepsis, SIRS and renal failure (p<0.05 for all). However, we did not find differences regarding the hospital use of RASi and the development of heart failure. CONCLUSION: RASi historic use, at admission, is not related to an adjusted worse prognosis in hospitalized COVID-19 patients, although it points out a high-risk population. In this setting, the in-hospital prescription of RASi is associated with improved survival and fewer short-term complications.

Anticoagulation Therapy in Patients With Coronavirus Disease 2019: Results From a Multicenter International Prospective Registry (Health Outcome Predictive Evaluation for Corona Virus Disease 2019 [HOPE-COVID19]).

OBJECTIVES: No standard therapy, including anticoagulation regimens, is currently recommended for coronavirus disease 2019. Aim of this study was to evaluate the efficacy of anticoagulation in coronavirus disease 2019 hospitalized patients and its impact on survival. DESIGN: Multicenter international prospective registry (Health Outcome Predictive Evaluation for Corona Virus Disease 2019). SETTING: Hospitalized patients with coronavirus disease 2019. PATIENTS: Five thousand eight hundred thirty-eight consecutive coronavirus disease 2019 patients. INTERVENTIONS: Anticoagulation therapy, including prophylactic and therapeutic regimens, was obtained for each patient. MEASUREMENTS AND MAIN RESULTS: Five thousand four hundred eighty patients (94%) did not receive any anticoagulation before hospitalization. Two-thousand six-hundred one patients (44%) during hospitalization received anticoagulation therapy and it was not associated with better survival rate (81% vs 81%; p = 0.94) but with higher risk of bleeding (2.7% vs 1.8%; p = 0.03). Among patients admitted with respiratory failure (49%, n = 2,859, including 391 and 583 patients requiring invasive and noninvasive ventilation, respectively), anticoagulation started during hospitalization was associated with lower mortality rates (32% vs 42%; p < 0.01) and nonsignificant higher risk of bleeding (3.4% vs 2.7%; p = 0.3). Anticoagulation therapy was associated with lower mortality rates in patients treated with invasive ventilation (53% vs 64%; p = 0.05) without increased rates of bleeding (9% vs 8%; p = 0.88) but not in those with noninvasive ventilation (35% vs 38%; p = 0.40). At multivariate Cox' analysis mortality relative risk with anticoagulation was 0.58 (95% CI, 0.49-0.67) in patients admitted with respiratory failure, 0.50 (95% CI, 0.49-0.67) in those requiring invasive ventilation, 0.72 (95% CI, 0.51-1.01) in noninvasive ventilation. CONCLUSIONS: Anticoagulation therapy in general population with coronavirus disease 2019 was not associated with better survival rates but with higher bleeding risk. Better results were observed in patients admitted with respiratory failure and requiring invasive ventilation.

Clinical profile and prognosis in patients on oral anticoagulation before admission for COVID-19.

BACKGROUND: The coronavirus disease 2019 (COVID-19) shows high morbidity and mortality, particularly in patients with concomitant cardiovascular diseases. Some of these patients are under oral anticoagulation (OAC) at admission, but to date, there are no data on the clinical profile, prognosis and risk factors of such patients during hospitalization for COVID-19. DESIGN: Subanalysis of the international 'real-world' HOPE COVID-19 registry. All patients with prior OAC at hospital admission for COVID-19 were suitable for the study. All-cause mortality was the primary endpoint. RESULTS: From 1002 patients included, 110 (60.9% male, median age of 81.5 [IQR 75-87] years, median Short-Form Charlson Comorbidity Index [CCI] of 1 [IQR 1-3]) were on OAC at admission, mainly for atrial fibrillation and venous thromboembolism. After propensity score matching, 67.9% of these patients died during hospitalization, which translated into a significantly higher mortality risk compared to patients without prior OAC (HR 1.53, 95% CI 1.08-2.16). After multivariate Cox regression analysis, respiratory insufficiency during hospitalization (HR 6.02, 95% CI 2.18-16.62), systemic inflammatory response syndrome (SIRS) during hospitalization (HR 2.29, 95% CI 1.34-3.91) and the Short-Form CCI (HR 1.24, 95% CI 1.03-1.49) were the main risk factors for mortality in patients on prior OAC. CONCLUSIONS: Compared to patients without prior OAC, COVID-19 patients on OAC therapy at hospital admission showed lower survival and higher mortality risk. In these patients on OAC therapy, the prevalence of several comorbidities is high. Respiratory insufficiency and SIRS during hospitalization, as well as higher comorbidity, pointed out those anticoagulated patients with increased mortality risk.

COVID-19 and the impact of arterial hypertension-An analysis of the international HOPE COVID-19 Registry (Italy-Spain-Germany).

BACKGROUND: A systematic analysis of concomitant arterial hypertension in COVID-19 patients and the impact of angiotensin-converting-enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARBs) have not been studied in a large multicentre cohort yet. We conducted a subanalysis from the international HOPE Registry (https://hopeprojectmd.com, NCT04334291) comparing COVID-19 in presence and absence of arterial hypertension. MATERIALS AND METHODS: Out of 5837 COVID-19 patients, 2850 (48.8%) patients had the diagnosis arterial hypertension. 1978/2813 (70.3%) patients were already treated with ACEI or ARBs. The clinical outcome of the present subanalysis included all-cause mortality over 40 days of follow-up. RESULTS: Patients with arterial hypertension suffered significantly more from different complications including respiratory insufficiency (60.8% vs 39.5%), heart failure (9.9% vs 3.1%), acute kidney injury (25.3% vs 7.3%), pneumonia (90.6% vs 86%), sepsis (14.7% vs 7.5%), and bleeding events (3.6% vs 1.6%). The mortality rate was 29.6% in patients with concomitant arterial hypertension and 11.3% without arterial hypertension (P < .001). Invasive and non-invasive respiratory supports were significantly more required in presence of arterial hypertension as compared without it. In the multivariate cox regression analysis, while age≥65, benzodiazepine, antidepressant at admission, elevated LDH or creatinine, respiratory insufficiency and sepsis might be a positive independent predictors of mortality, antiviral drugs, interferon treatment, ACEI or ARBs at discharge or oral anticoagulation at discharge might be an independent negative predictor of the mortality. CONCLUSIONS: The mortality rate and in-hospital complications might be increased in COVID-19 patients with a concomitant history of arterial hypertension. The history of ACEI or ARBs treatments does not seem to impact the outcome of these patients.

Usefulness of oral anticoagulation in patients with coronary aneurysms: Insights from the CAAR registry.

OBJECTIVES: To assess the Usefulness of oral anticoagulation therapy (OAT) in patients with coronary artery aneurysm (CAA). BACKGROUND: Data on the most adequate antithrombotic CAA management is lacking. METHODS: Patients included in CAAR (Coronary Artery Aneurysm Registry, Clinical Trials.gov: NCT02563626) were selected. Patients were divided in OAT and non-OAT groups, according to anticoagulation status at discharge and 2:1 propensity score matching with replacement was performed. The primary endpoint of the analysis was a composite and mutual exclusive endpoint of myocardial infarction, unstable angina (UA), and aneurysm thrombosis (coronary ischemic endpoint). Net adverse clinical events, major adverse cardiovascular events, their single components, cardiovascular death, re-hospitalizations for heart failure, stroke, aneurysm thrombosis, and bleeding were the secondary ones. RESULTS: One thousand three hundred thirty-one patients were discharged without OAT and 211 with OAT. In the propensity-matched sample (390 patients in the non-OAT group, 195 patients in the OAT group), after 3 years of median follow-up (interquartile range 1-6 years), the rate of the primary endpoint (coronary ischemic endpoint) was significantly less in the OAT group as compared to non-OAT group (8.7 vs. 17.2%, respectively; p = .01), driven by a significant reduction in UA (4.6 vs. 10%, p < .01) and aneurysm thrombosis (0 vs. 3.1%, p = .03), along with a non-significant reduction in MI (4.1 vs. 7.7%, p = .13). A non-significant increase in bleedings, mainly BARC type 1 (55%), was found in the OAT-group (10.3% in the non-OAT vs. 6.2% in the OAT group, p = .08). CONCLUSION: OAT decreases the composite endpoint of UA, myocardial infarction, and aneurysm thrombosis in patients with CAA, despite a non-significant higher risk of bleeding.

COVID-19 anosmia and gustatory symptoms as a prognosis factor: a subanalysis of the HOPE COVID-19 (Health Outcome Predictive Evaluation for COVID-19) registry.

Olfactory and gustatory dysfunctions (OGD) are a frequent symptom of coronavirus disease 2019 (COVID-19). It has been proposed that the neuroinvasive potential of the novel SARS-CoV-2 could be due to olfactory bulb invasion, conversely studies suggest it could be a good prognostic factor. The aim of the current study was to investigate the prognosis value of OGD in COVID-19. These symptoms were recorded on admission from a cohort study of 5868 patients with confirmed or highly suspected COVID-19 infection included in the multicenter international HOPE Registry (NCT04334291). There was statistical relation in multivariate analysis for OGD in gender, more frequent in female 12.41% vs 8.67% in male, related to age, more frequent under 65 years, presence of hypertension, dyslipidemia, diabetes, smoke, renal insufficiency, lung, heart, cancer and neurological disease. We did not find statistical differences in pregnant (p = 0.505), patient suffering cognitive (p = 0.484), liver (p = 0.1) or immune disease (p = 0.32). There was inverse relation (protective) between OGD and prone positioning (0.005) and death (< 0.0001), but no with ICU (0.165) or mechanical ventilation (0.292). On univariable logistic regression, OGD was found to be inversely related to death in COVID-19 patients. The odds ratio was 0.26 (0.15-0.44) (p < 0.001) and Z was - 5.05. The presence of anosmia is fundamental in the diagnosis of SARS.CoV-2 infection, but also could be important in classifying patients and in therapeutic decisions. Even more knowing that it is an early symptom of the disease. Knowing that other situations as being Afro-American or Latino-American, hypertension, renal insufficiency, or increase of C-reactive protein (CRP) imply a worse prognosis we can make a clinical score to estimate the vital prognosis of the patient. The exact pathogenesis of SARS-CoV-2 that causes olfactory and gustative disorders remains unknown but seems related to the prognosis. This point is fundamental, insomuch as could be a plausible way to find a treatment.

Clinical profile and predictors of in-hospital mortality among older patients hospitalised for COVID-19.

BACKGROUND: the coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and mortality, particularly in older patients. METHODS: post hoc analysis of the international, multicentre, 'real-world' HOPE COVID-19 registry. All patients aged ≥65 years hospitalised for COVID-19 were selected. Epidemiological, clinical, analytical and outcome data were obtained. A comparative study between two age subgroups, 65-74 and ≥75 years, was performed. The primary endpoint was all cause in-hospital mortality. RESULTS: about, 1,520 patients aged ≥65 years (60.3% male, median age of 76 [IQR 71-83] years) were included. Comorbidities such as hypertension (69.2%), dyslipidaemia (48.6%), cardiovascular diseases (any chronic heart disease in 38.4% and cerebrovascular disease in 12.5%), and chronic lung disease (25.3%) were prevalent, and 49.6% were on ACEI/ARBs. Patients aged 75 years and older suffered more in-hospital complications (respiratory failure, heart failure, renal failure, sepsis) and a significantly higher mortality (18.4 vs. 48.2%, P < 0.001), but fewer admissions to intensive care units (11.2 vs. 4.8%). In the overall cohort, multivariable analysis demonstrated age ≥75 (OR 3.54), chronic kidney disease (OR 3.36), dementia (OR 8.06), peripheral oxygen saturation at admission <92% (OR 5.85), severe lymphopenia (<500/mm3) (OR 3.36) and qSOFA (Quick Sequential Organ Failure Assessment Score) >1 (OR 8.31) to be independent predictors of mortality. CONCLUSION: patients aged ≥65 years hospitalised for COVID-19 had high rates of in-hospital complications and mortality, especially among patients 75 years or older. Age ≥75 years, dementia, peripheral oxygen saturation <92%, severe lymphopenia and qSOFA scale >1 were independent predictors of mortality in this population.

Acute Myocardial Infarction Complicated by Cardiogenic Shock: Analysis of the Position Statement From the European Society of Cardiology Acute Cardiovascular Care Association, With Perioperative Implications.

Effective management of cardiogenic shock (CS) is hampered by a lack of evidence-based information. This is a high-mortality condition, without clear, evidence-based guidelines for perioperative management, specifically-a lack of target endpoints for treatment (e.g.: mean arterial pressure or oxygenation), utility of regional care systems or the benefits of palliative care. The Acute Cardiovascular Care Association (ACCA) of the European Society of Cardiology (ESC) recently published a position statement that aimed to offer contemporary guidance on the diagnosis and treatment of acute myocardial infarction (AMI) complicated by CS. Herein, we review this complex clinical topic and review the ACCA statement on AMI associated with CS, with a focus on relevance to perioperative management.

Non-invasive ventilation for SARS-CoV-2 acute respiratory failure: a subanalysis from the HOPE COVID-19 registry.

BACKGROUND: The COVID-19 pandemic has seriously challenged worldwide healthcare systems and limited intensive care facilities, leading to physicians considering the use of non-invasive ventilation (NIV) for managing SARS-CoV-2-related acute respiratory failure (ARF). METHODS: We conducted an interim analysis of the international, multicentre HOPE COVID-19 registry including patients admitted for a confirmed or highly suspected SARS-CoV-2 infection until 18 April 2020. Those treated with NIV were considered. The primary endpoint was a composite of death or need for intubation. The components of the composite endpoint were the secondary outcomes. Unadjusted and adjusted predictors of the primary endpoint within those initially treated with NIV were investigated. RESULTS: 1933 patients who were included in the registry during the study period had data on oxygen support type. Among them, 390 patients (20%) were treated with NIV. Compared with those receiving other non-invasive oxygen strategy, patients receiving NIV showed significantly worse clinical and laboratory signs of ARF at presentation. Of the 390 patients treated with NIV, 173 patients (44.4%) met the composite endpoint. In-hospital death was the main determinant (147, 37.7%), while 62 patients (15.9%) needed invasive ventilation. Those requiring invasive ventilation had the lowest survival rate (41.9%). After adjustment, age (adjusted OR (adj(OR)) for 5-year increase: 1.37, 95% CI 1.15 to 1.63, p<0.001), hypertension (adj(OR) 2.95, 95% CI 1.14 to 7.61, p=0.03), room air O2 saturation <92% at presentation (adj(OR) 3.05, 95% CI 1.28 to 7.28, p=0.01), lymphocytopenia (adj(OR) 3.55, 95% CI 1.16 to 10.85, p=0.03) and in-hospital use of antibiotic therapy (adj(OR) 4.91, 95% CI 1.69 to 14.26, p=0.003) were independently associated with the composite endpoint. CONCLUSION: NIV was used in a significant proportion of patients within our cohort, and more than half of these patients survived without the need for intubation. NIV may represent a viable strategy particularly in case of overcrowded and limited intensive care resources, but prompt identification of failure is mandatory to avoid harm. Further studies are required to better clarify our hypothesis. TRIAL REGISTRATION NUMBERS: NCT04334291/EUPAS34399.

Clinical Profile and 30-Day Mortality of Invasively Managed Patients with Suspected Acute Coronary Syndrome During the COVID-19 Outbreak.

The COVID-19 pandemic severely disrupted cardiovascular care during the spring of 2020 in Europe. Our study analyzed the clinical profile, COVID-19 impact, and 30-day prognosis of invasively managed patients with acute coronary syndrome (ACS) compared to a historical cohort.All invasively managed ACS patients from March 1st to April 30th, 2020 were compared to a cohort from the same timeframe of 2019 (n = 316). COVID-19 confirmed cases were defined by a positive SARS-CoV-2 polymerase chain reaction (PCR) test (CoV+). The primary outcome was all-cause 30-day mortality and multivariable predictors of this outcome.A 40.4% reduction in ACS patients was noted (198 cases in 2019 to 118 in 2020), and 11% of 2020 ACS patients were CoV+. Baseline characteristics were similar between groups. There were significantly more in-hospital patients with ACS (15.3% versus 6.1%, P = 0.007), and fewer patients were found to have a culprit lesion (58.5% versus 74.2%, P = 0.004) in 2020 compared to 2019. Thirty-day mortality in 2020 (7%) was not different from that in 2019 (4.2%), P = 0.294, but it was significantly higher in CoV+ patients (23.1%) compared to that in negative SARS-CoV-2 PCR test (CoV-) patients (5%), P = 0.047, in the 2020 group. In the multivariate analysis, CoV+ was an independent mortality predictor (OR = 9.8, 95% CI = 1.48-64.78), along with the left ventricular ejection fraction (LVEF) (OR = 0.91, 95% CI = 0.86-0.97), P = 0.0006.This study found increased 30-day mortality of invasively managed CoV+ ACS patients compared to that of CoV- patients during the 2020 COVID-19 spring outbreak. In the multivariable analysis, a SARS-CoV-2 positive test was independently associated with 30-day mortality. Further investigations of the underlying physiopathological relations between COVID-19 and ACS are warranted.

Short-term clinical outcomes of percutaneous coronary intervention of unprotected left main coronary disease in cardiogenic shock.

BACKGROUND: Percutaneous coronary intervention (PCI) of left main (LM) disease in patients with cardiogenic shock (CS) represents a clinical challenge. Evidence on clinical outcomes according to revascularization strategies in this scenario remains scarce. The objective was to investigate the short-term outcomes according to treatment strategies for this population. METHODS: We retrospectively analyzed 78 consecutive patients who underwent PCI of LM in established CS at two experienced centers. Characteristics of PCI and short-term clinical outcomes were assessed. RESULTS: LM stenosis was considered the culprit lesion in 49 patients (62.8%). In the remaining cases, LM stenosis was treated after successful PCI of the culprit vessel because of persistent CS. The majority of patients presented complex coronary anatomy (43.6% had Syntax score > 32). Complete revascularization was performed in 34.6%; a 2-stents technique in the LM bifurcation was used in 12.8% and intra-aortic balloon pump (IABP) in 73.1%. In-hospital mortality was 48.7%. At 90 days follow-up it was 50% without differences between 1 or 2 stent LM bifurcation-techniques (p = .319). Mortality was higher in patients with partial revascularization and residual Syntax score ≥ 15 (p < .05 by univariate analysis), and in those with TIMI flow<3 in the left coronary artery at the end of PCI (p < .05 by multivariate analysis). There were no significant differences in the use of IABP in relation to 90-day mortality (p = .92). CONCLUSIONS: In patients presenting with cardiogenic shock and LM disease, neither 2-stents strategy in the LM nor use of IABP displayed a reduced short-term mortality. However, patients with final TIMI flow <3 presented higher short-term mortality in our series.

Elevation of ST-segment in aVR is predictive of cardiogenic shock but not of multivessel disease in inferior myocardial infarction.

INTRODUCTION: Some studies suggest that ST elevation in aVR (aVR-STE) can predict the presence of left main or multivessel disease (MVD) and relates to prognosis. Our purpose was to analyze the relationship of aVR-STE to MVD disease or cardiogenic shock (CS) in patients with inferior myocardial infarction (inferior STEMI). METHODS: We analyzed two cohorts of consecutive patients admitted for inferior STEMI in the Coronary Unit of two university hospitals. ST elevation and ST depression in each derivation were compared between patients with and without MVD and with and without CS. RESULTS: We included 342 patients-19.6% women and 80.4% men-with a median age of 60 (52, 70); 18 patients (5.2%) had MVD, and 25 (7.3%) patients presented CS. There was no relationship between ST elevation or ST depression in either derivation and MVD. In contrast, CS was associated with aVR-STE, ST-segment depression in lead aVL, and the sum of ST-segment depression. aVR-STE of 0.25 mm had a sensitivity of 24.0% and a specificity of 95.9% for CS. After multivariate analysis including clinical variables, aVR-STE was independently associated with CS. CONCLUSIONS: In patients with inferior STEMI, ST-segment analysis was not useful in predicting multivessel disease. aVR-STE was an independent predictor of CS, with high specificity but low sensitivity.

Management of Arterial Hypertension: 2018 ACC/AHA Versus ESC Guidelines and Perioperative Implications.

Hypertension is the most prevalent cardiovascular risk factor worldwide and the leading cause of death and premature morbidity. Despite its prevalence, evaluation and management are nonuniform despite multiple society guidelines worldwide. Guidelines from scientific societies aim to provide standardized recommendations based on the scientific evidence available. In addition, several expert-based recommendations are provided in these documents, a situation that can lead to confusion. The scope of this manuscript is to briefly compare the recent updated guidelines for the management of arterial hypertension from the American College of Cardiology/American Heart Association and the European Society of Cardiology/European Society of Hypertension and their relevant differences, which are important to the practicing clinician.

Analysis of Bioprosthetic Aortic Valve Thrombosis-Implications and Management Strategies.

Aortic valve disease is a common condition whose prevalence is increasing, especially in Western countries. Two main families of cardiac prostheses are available: mechanical and biological prostheses. Nevertheless, the use of mechanical surgical valves has declined significantly over time in favor of bioprosthetic surgical valves even among middle-aged patients. The dominance of bioprosthetic valves was enhanced further with the introduction of transcatheter aortic valves. However, some concerns have arisen in recent years about clinical and subclinical leaflet thrombosis of both surgical and transcatheter bioprostheses. This manuscript aims to discuss the current evidence relating to the incidence, pathophysiology, clinical implications, and management strategies of biological valve leaflet thrombosis.

Comparison of local versus general anesthesia in patients undergoing transcatheter aortic valve replacement: A meta-analysis.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is typically performed under general anesthesia (GA). However, there is increasing data supporting the safety of performing TAVR under local anesthesia/conscious sedation (LA). We performed a meta-analysis to gain better understanding of the safety and efficacy of LA versus GA in patients with severe aortic stenosis undergoing TAVR. METHODS AND RESULTS: We comprehensively searched EMBASE, PubMed, and Web of Science. Effect sizes were summarized using risk ratios (RRs) difference of the mean (DM), and 95% CIs (confidence intervals) for dichotomous and continuous variables respectively. Twenty-six studies and 10,572 patients were included in the meta-analysis. The use of LA for TAVR was associated with lower overall 30-day mortality (RR, 0.73; 95% CI, 0.57-0.93; P = 0.01), use of inotropic/vasopressor drugs (RR, 0.45; 95% CI, 0.28-0.72; P < 0.001), hospital length of stay (LOS) (DM, -2.09; 95% CI, -3.02 to -1.16; P < 0.001), intensive care unit LOS (DM, -0.18; 95% CI, -0.31 to -0.04; P = 0.01), procedure time (DM, -25.02; 95% CI, -32.70 to -17.35; P < 0.001); and fluoroscopy time (DM, -1.63; 95% CI, -3.02 to -0.24; P = 0.02). No differences were observed between LA and GA for stroke, cardiovascular mortality, myocardial infarction, permanent pacemaker implantation, acute kidney injury, paravalvular leak, vascular complications, major bleeding, procedural success, conduction abnormalities, and annular rupture. CONCLUSION: Our meta-analysis suggests that use of LA for TAVR is associated with a lower 30-day mortality, shorter procedure time, fluoroscopy time, ICU LOS, hospital length of stay, and reduced need for inotropic support.
