Sex differences in trends and outcomes of acute myocardial infarction with mechanical complications in the United States.

BACKGROUND: Mechanical complications (MC) are rare but significant sequelae of acute myocardial infarction (AMI). Current data on sex differences in AMI with MC is limited. METHODS: We queried the National Inpatient Sample database to identify adult patients with the primary diagnosis of AMI and MC. The main outcome of interest was sex difference in-hospital mortality. Secondary outcomes were sex differences in the incidence of acute kidney injury (AKI), major bleeding, use of inotropes, permanent pacemaker implantation (PPMI), performance of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), surgery (VSD repair and MV surgery), pericardiocentesis, use of mechanical circulatory support (MCS), ischemic stroke, and mechanical ventilation. RESULTS: Among AMI-MC cohort, in-hospital mortality was higher among females compared to males (41.24% vs 28.13%: aOR 1.39. 95% CI 1.079-1.798; p = 0.01). Among those who had VSD, females also had higher in-hospital mortality compared to males (56.7% vs 43.1%: aOR 1.74, 95% CI 1.12-2.69; p = 0.01). Females were less likely to receive CABG compared to males (12.03% vs 20%: aOR 0.49 95% CI 0.345-0.690; p < 0.001). CONCLUSION: Despite the decreasing trend in AMI admission, females had higher risk of MC and associated mortality. Significant sex disparities still exist in AMI treatment.

End-Of-Life Care for Patients With End-Stage Heart Failure, Comparisons of International Guidelines.

Heart failure (HF) is a chronic, debilitating condition associated with significant morbidity, mortality, and socioeconomic burden. Patients with end-stage HF (ESHF) who are not a candidate for advanced therapies will continue to progress despite standard medical therapy. Thus, the focus of care shifts from prolonging life to controlling symptoms and improving quality of life through palliative care (PC). Because the condition and prognosis of HF patients evolve and can rapidly deteriorate, it is imperative to begin the discussion on end-of-life (EOL) issues early during HF management. These include the completion of an advance directive, do-not-resuscitate orders, and policies on device therapy and discontinuation as part of advance care planning (ACP). ESHF patients who do not have indications for advanced therapies or those who wish not to have a left ventricular assist device (LVAD) or heart transplant (HT) often experience high symptom burden despite adequate medical management. The proper identification and assessment of symptoms such as pain, dyspnea, nausea, depression, and anxiety are essential to the management of ESHF and may be underdiagnosed and undertreated. Psychological support and spiritual care are also crucial to improving the quality of life during EOL. Caregivers of ESHF patients must also be provided supportive care to prevent compassion fatigue and improve resilience in patient care. In this narrative review, we compare the international guidelines and provide an overview of end-of-life and palliative care for patients with ESHF.

Association between number of vasopressors and mortality in COVID-19 patients.

Study objective: Study the clinical outcomes associated with the number of concomitant vasopressors used in critically ill COVID-19 patients. Design: A single-center retrospective cohort study was conducted on patients admitted with COVID-19 to the intensive care unit (ICU) between March and October 2020. Setting: Rush University Medical Center, United States. Participants: Adult patients at least 18 years old with COVID-19 with continuous infusion of any vasopressors were included. Main outcome measures: 60-day mortality in COVID-19 patients by the number of concurrent vasopressors received. Results: A total of 637 patients met our inclusion criteria, of whom 338 (53.1 %) required the support of at least one vasopressor. When compared to patients with no vasopressor requirement, those who required 1 vasopressor (V1) (adjusted odds ratio [aOR] 3.27, 95 % confidence interval (CI) 1.86-5.79, p < 0.01) (n = 137), 2 vasopressors (V2) (aOR 4.71, 95 % CI 2.54-8.77, p < 0.01) (n = 86), 3 vasopressors (V3) (aOR 26.2, 95 % CI 13.35-53.74 p < 0.01) (n = 74), and 4 or 5 vasopressors(V4-5) (aOR 106.38, 95 % CI 39.17-349.93, p < 0.01) (n = 41) were at increased risk of 60-day mortality. In-hospital mortality for patients who received no vasopressors was 6.7 %, 22.6 % for V1, 27.9 % for V2, 62.2 % for V3, and 78 % for V4-V5. Conclusion: Critically ill patients with COVID-19 requiring vasopressors were associated with significantly higher 60-day mortality.

Clinical outcomes of COVID-19 infection in patients with pre-existing cardiovascular disease.

Introduction: Patients with pre-existing cardiovascular disease may carry a higher risk for mortality from COVID-19. This study examined the association between individuals with pre-existing cardiovascular disease admitted for COVID-19 and their clinical outcomes. Methods: A retrospective cohort study was conducted on patients admitted with COVID-19 to Rush University System for Health (RUSH) to identify cardiovascular risk factors associated with increased mortality and major adverse cardiovascular events (MACE; a composite of cardiovascular death, stroke, myocardial injury, and heart failure exacerbation). Multivariable logistic regression was used to adjust for demographic data and comorbid conditions. Results: Of the 1682 patients who met inclusion criteria, the median age was 59. Patients were predominantly African American (34.4 %) and male (54.5 %). Overall, 202 (12 %) patients suffered 60-day mortality. In the multivariable model that assessed risk factors for 60-day mortality, age 60-74 (adjusted odds ratio [aOR] 3.30 [CI: 1.23-10.62]; p < 0.05) and age 75-100 (aOR 4.52 [CI: 1.46-16.15]; p < 0.05) were significant predictors when compared to those aged 19 to 39. This model also showed that those with past medical histories of atrial fibrillation (aOR 2.47 [CI: 1.38-4.38]; p < 0.01) and venous thromboembolism (aOR 2.00 [CI: 1.12-3.50]; p < 0.05) were at higher risk of 60-day mortality. Conclusion: In this cohort, patients over 60 years old with a pre-existing history of atrial fibrillation and venous thromboembolism were at increased risk of mortality from COVID-19.

Sex Differences in Takotsubo Syndrome: A Narrative Review.

Takotsubo syndrome (TTS), or apical ballooning syndrome, is a transient and usually reversible form of cardiac dysfunction. It has classically been described in women with cardiac susceptibility when exposed to emotional or physical stress. Various hypotheses on the pathophysiology of TTS have been suggested, but the underlying mechanism remains unknown. There is increasing recognition of the sex differences in the presentation, triggers, severity, and complications of TTS. A literature review was conducted and found 75 relevant articles on PubMed Cochrane Library, and Google Scholar from 2001 to 2019 regarding TTS. We found remarkable sex differences existed in the underlying triggers, pathophysiology, illness severity, complications, and mortality. However, no sex differences were identified for baseline transthoracic echocardiogram findings, age at presentation, presenting symptoms, recurrence, and treatment approach. Much information regarding TTS remain lacking, but collaboration of national and international registries will be beneficial in addressing these gaps.
