RESUMO
BACKGROUND: There has been an evolution in the disease severity and complexity of patients presenting to the cardiac intensive care unit (CICU). There are limited data evaluating the role of palliative care in contemporary CICU practice. METHODS: PubMed Central, CINAHL, EMBASE, Medline, Cochrane Library, Scopus, and Web of Science databases were evaluated for studies on palliative care in adults (≥18 years) admitted with acute cardiovascular conditions - acute myocardial infarction, cardiogenic shock, cardiac arrest, advanced heart failure, post-cardiac surgery, spontaneous coronary artery dissection, Takotsubo cardiomyopathy, and pulmonary embolism - admitted to the CICU, coronary care unit or cardiovascular intensive care unit from 1/1/2000 to 8/8/2022. The primary outcome of interest was the utilization of palliative care services. Secondary outcomes of included studies were also addressed. Meta-analysis was not performed due to heterogeneity. RESULTS: Of 5711 citations, 30 studies were included. All studies were published in the last seven years and 90 % originated in the United States. Twenty-seven studies (90 %) were retrospective analyses, with a majority from the National Inpatient Sample database. Heart failure was the most frequent diagnosis (47 %), and in-hospital mortality was reported in 67 % of studies. There was heterogeneity in the timing, frequency, and background of the care team that determined palliative care consultation. In two randomized trials, there appeared to be improvement in quality of life without an impact on mortality. CONCLUSIONS: Despite the growing recognition of the role of palliative care, there are limited data on palliative care consultation in the CICU.
RESUMO
Background: Over the past decade there has been increasing interest in critical care medicine (CCM) training for cardiovascular medicine (CV) physicians either in isolation (separate programs in either order [CV/CCM], integrated critical care cardiology [CCC] training) or hybrid training with interventional cardiology (IC)/heart failure/transplant (HF) with targeted CCC training. Objective: To review the contemporary landscape of CV/CCM, CCC, and hybrid training. Methods: We reviewed the literature from 2000-2022 for publications discussing training in any combination of internal medicine CV/CCM, CCC, and hybrid training. Information regarding training paradigms, scope of practice and training, duration, sequence, and milestones was collected. Results: Of the 2,236 unique citations, 20 articles were included. A majority were opinion/editorial articles whereas two were surveys. The training pathways were classified into - (i) specialty training in both CV (3 years) and CCM (1-2 years) leading to dual American Board of Internal Medicine (ABIM) board certification, or (ii) base specialty training in CV with competencies in IC, HF or CCC leading to a non-ABIM certificate. Total fellowship duration varied between 4-7 years after a three-year internal medicine residency. While multiple articles commented on the ability to integrate the fellowship training pathways into a holistic and seamless training curriculum, few have highlighted how this may be achieved to meet competencies and standards. Conclusions: In 20 articles describing CV/CCM, CCC, and hybrid training, there remains significant heterogeneity on the standardized training paradigms to meet training competencies and board certifications, highlighting an unmet need to define CCC competencies.
RESUMO
BACKGROUND: We sought to evaluate respiratory complications in heart failure patients undergoing left atrial appendage occlusion (LAAO) for stroke prevention in atrial fibrillation. METHODS: Adult admissions (>18 years) undergoing LAAO during 2016-2020 were identified from the National Inpatient Sample. Heart failure (HF) was stratified into systolic (SHF) and diastolic heart failure (DHF) and were compared to those without HF. Outcomes of interested included acute respiratory failure, use of non-invasive and invasive mechanical ventilation, and in-hospital mortality. RESULTS: Of 74,440 admissions for atrial fibrillation undergoing LAAO, SHF and DHF were noted in 8335 (11.2%) and 10,925 (14.7%), respectively. The SHF cohort was predominantly male (78%) whereas DHF cohort were female (53%). Compared to those without HF, presence of SHF (2.3% vs. 0.6%; adjusted odds ratio [OR] 1.61 [95% confidence interval {CI} 1.10-2.36]; p = 0.01) and DHF (2.8% vs. 0.6%; adjusted OR 2.20 [95% CI 1.58-3.06]; p < 0.001) were associated with higher rates of acute respiratory failure. SHF (1.7% vs. 0.6%; adjusted OR 1.70 [95% CI 1.07-2.71]; p = 0.02) group but not DHF (1.2% vs. 0.6%; adjusted OR 1.21 [95% CI 0.78-1.89]; p = 0.39) was associated with higher rates of non-invasive ventilation, whereas the DHF group (0.9% vs. 0.2%; adjusted OR 1.91 [95% CI 1.08-3.34]; p = 0.02) but not SHF (0.8% vs. 0.2%; adjusted OR 1.54 [95% CI 0.83-2.84]; p = 0.17) was associated with higher rates of invasive mechanical ventilation use. In-hospital mortality was comparable between cohorts. CONCLUSION: Compared to those without HF, atrial fibrillation admissions with HF undergoing LAAO had higher rates of acute respiratory failure and mechanical ventilation rates without differences in in-hospital mortality.

There are limited and conflicting data on the initial management of intermediate-risk (or submassive) pulmonary embolism (PE). This study sought to compare the outcomes of catheter-directed thrombolysis (CDT) in combination with systemic anticoagulation (SA) to SA alone. A systematic search was conducted in MEDLINE, EMBASE, PubMed, and the Cochrane databases from inception to March 1, 2023 for studies comparing the outcomes of CDT + SA versus SA alone in intermediate-risk PE. The outcomes were in-hospital, 30-day, 90-day, and 1-year mortality; bleeding; blood transfusion; right ventricular recovery; and length of stay. Random-effects models was used to calculate the pooled incidence and risk ratios (RRs) with 95% confidence intervals (CIs). A total of 15 (2 randomized and 13 observational) studies with 10,549 (2,310 CDT + SA and 8,239 SA alone) patients were included. Compared with SA, CDT + SA was associated with significantly lower in-hospital mortality (RR 0.41, 95% CI 0.30 to 0.56, p <0.001), 30-day mortality (RR 0.34, 95% CI 0.18 to 0.67, p = 0.002), 90-day mortality (RR 0.34, 95% CI 0.17 to 0.67, p = 0.002), and 1-year mortality (RR 0.58, 95% CI 0.34 to 0.97, p = 0.04). There were no significant differences between the 2 cohorts in the rates of major bleeding (RR 1.39, 95% CI 0.72 to 2.68, p = 0.56), minor bleeding (RR 1.83, 95% CI 0.97 to 3.46, p = 0.06), and blood transfusion (RR 0.34, 95% CI 0.10 to 1.15, p = 0.08). In conclusion, CDT + SA is associated with significantly lower short-term and long-term all-cause mortality, without any differences in major/minor bleeding, in patients with intermediate-risk PE.

A 36-year-old pregnant woman with a prior history of depression and recent gunshot wounds presented with sudden deterioration in her mental status. Clinical examination revealed psychosis, hallucinations, and lack of orientation, with an otherwise normal neurological and cardiorespiratory examination. Computed tomographic scan of her head was normal, and she was diagnosed with acute psychosis and excited delirium. She did not respond to supraphysiologic dosages of antipsychotic therapy and needed physical restraints for combativeness and agitation. Her cerebrospinal fluid analysis was negative for an infectious etiology, but was positive for anti-N-methyl-D-aspartate receptor encephalitis antibodies. Abdominal imaging revealed a right-sided ovarian cyst. Subsequently she underwent right-sided oophorectomy. Postoperatively the patient continued to have intermittent episodes of agitation requiring antipsychotic medications. Later, she was safely transitioned to home care with family support.
RESUMO
A 65-year-old male presented with chest pain, tachycardia, tachypnea, and diminished breath sounds. His lab investigations revealed an elevated leukocyte count, erythrocyte sedimentation rate, and B-type natriuretic peptide. Transthoracic echocardiography and chest imaging revealed the presence of pericardial effusion without tamponade and he was treated for presumed acute idiopathic pericarditis. He was started on indomethacin and colchicine but he stopped them prematurely due to side effects. Subsequently, he developed pleural effusions and ascites requiring multiple thoracenteses and paracenteses. Due to equivocal echocardiographic findings, he underwent invasive hemodynamic measurements which demonstrated equalization of filling pressures and ventricular interdependence, confirming constrictive pericarditis. Due to ongoing pericardial inflammation on cardiovascular magnetic resonance imaging, he was treated with a prednisone taper. Due to persistent symptoms and fibrosis of the pericardium on cross-section imaging, he underwent pericardiectomy. He did well with the procedure and has had an uneventful clinical follow-up.
RESUMO
There has been much interest in the possible adverse events associated with available anti-coronavirus disease of 2019 (COVID-19) vaccines, given the rapid pace at which they had to be developed during the pandemic. One such adverse event is myocarditis post-COVID-19 vaccination. Several pathophysiological mechanisms have been proposed that might help us understand the relationship between the messenger ribonucleic acid (mRNA) vaccine and the occurrence of myocarditis, though we are yet to ascertain the causal link between them. Although the actual absolute incidence of myocarditis post-COVID-19 vaccination remains low among the large, general population that has been vaccinated, there has been a high relative incidence of this adverse event. We aim to review the existing literature and bring to light what we have so far understood with respect to the association between COVID-19 vaccination and myocarditis. This will help in better understanding the burden of the pathology along with alleviating apprehensions associated with it.

ABSTRACT: Sepsis is a multisystem disease process, which constitutes a significant public health challenge and is associated with high morbidity and mortality. Among other systems, sepsis is known to affect the cardiovascular system, which may manifest as myocardial injury, arrhythmias, refractory shock, and/or septic cardiomyopathy. Septic cardiomyopathy is defined as the reversible systolic and/or diastolic dysfunction of one or both ventricles. Left ventricle dysfunction has been extensively studied in the past, and its prognostic role in patients with sepsis is well documented. However, there is relatively scarce literature on right ventricle (RV) dysfunction and its role. Given the importance of timely detection of septic cardiomyopathy and its bearing on prognosis of patients, the role of RV dysfunction has come into renewed focus. Hence, through this review, we sought to describe the pathophysiology of RV dysfunction in sepsis and what have we learnt so far about its multifactorial nature. We also elucidate the roles of different biomarkers for its detection and prognosis, along with appropriate management of such patient population.

BACKGROUND: Cardiogenic shock (CS) is associated with high morbidity and mortality. In recent times, there is increasing interest in the role of angiotensin II in CS. We sought to systematically review the current literature on the use of angiotensin II in CS. METHODS: PubMed, EMBASE, Medline, Web of Science, PubMed Central, and CINAHL databases were systematically searched for studies that evaluated the efficacy of angiotensin II in patients with CS during 01/01/2010-07/07/2022. Outcomes of interest included change in mean arterial pressure (MAP), vasoactive medication requirements (percent change in norepinephrine equivalent [NEE] dose), all-cause mortality, and adverse events. RESULTS: Of the total 2,402 search results, 15 studies comprising 195 patients were included of which 156 (80%) received angiotensin II. Eleven patients (84.6%) in case reports and case series with reported MAP data at hour 12 noted an increase in MAP. Two studies noted a positive hemodynamic response (defined a priori) in eight (88.9%) and five (35.7%) patients. Eight studies reported a reduction in NEE dose at hour 12 after angiotensin II administration and one study noted a 100% reduction in NEE dose. Out of 47 patients with documented information, 13 patients had adverse outcomes which included hepatic injury (2), digital ischemia (1), ischemic optic neuropathy (1), ischemic colitis (2), agitated delirium (1), and thrombotic events (2). CONCLUSIONS: In this first systematic review of angiotensin II in CS, we note the early clinical experience. Angiotensin II was associated with improvements in MAP, decrease in vasopressor requirements, and minimal reported adverse events.

Type 2 diabetes mellitus (T2DM) has a heavy disease burden and is one of the leading causes of death worldwide. It is considered to be evolving from a complex and multifactorial metabolic disorder to an inflammatory condition. The strong link between hyperglycemia and oxidative stress has long been established. Oxidative stress leads to the generation of inflammatory mediators and reactive oxygen species, which results in an inflammatory state, which plays a key role in the pathogenesis of diabetic complications. Vitamin D is also known to affect insulin sensitivity. We aimed to correlate the levels of glycated hemoglobin (HbA1c) and vitamin D with oxidative stress. This cross-sectional study included 100 patients with T2DM. Oxidative stress was estimated by lipid peroxidation assay for activity of malondialdehyde (MDA), as well as superoxide dismutase (SOD) levels. HbA1c was estimated using ion-exchange chromatography. Vitamin D was estimated using enzyme-linked immunosorbent assay. The data were analyzed using a t test. The results showed that as the duration of T2DM increased, the levels of SOD and MDA also increased. No significant correlation was found between SOD and MDA with HbA1c (P = 0.995 and 0.195) and vitamin D (P = 0.874 and 0.051), respectively.

Barrett's esophagus (BE) is the only known precursor of esophageal adenocarcinoma (EAC) and is amenable to treatment. However, more than 90 percent of EAC patients are never diagnosed with antecedent BE. Identification of molecular markers for BE is needed to improve detection of BE through efficient non-endoscopic methods that are cost-effective, sensitive and can be used to cater to a larger group of the population at risk. Alterations in mitochondria and mitochondrial DNA have been shown to be associated with various cancers, including esophageal cancer. Mitochondrial response to oxidative stress, alterations in mitochondrial metabolism, changes in mitochondrial membrane potential and mitochondrial genetic mutations have been found to be associated with BE pathogenesis. This mini-review focuses on the role of mitochondria in the pathogenesis of BE and EAC and the prospects of using that knowledge to develop effective strategies for the improved detection and risk-stratification in BE patients.
