Rare Variant of Meigs Syndrome Associated With Pericardial Effusion.

Meigs syndrome is an uncommon entity associated with benign ovarian tumor, pleural effusion, and ascites. Its association with pericardial effusion is extremely rare. We report a case of Meigs syndrome associated with recurrent pericardial effusion that resolved after surgical resection of the ovarian tumor. (Level of Difficulty: Beginner.).

Spontaneous Coronary Artery Dissection Case Series: Clinical Presentation, Angiographic Imaging, Management, and Outcomes.

Spontaneous coronary artery dissection (SCAD) is a rare but more frequently recognized cause of acute coronary syndrome. Due to the low incidence rate of this condition, there are no consensus guidelines to treat this clinical entity. Most of the information on the clinical presentation and management of SCAD originates from case reports and series; however, there has not been yet a prospective randomized study to guide treatment of SCAD. It is mostly seen in women and particularly those of younger ages. Most cases have an underlying etiology although the underlying pathophysiology is not fully understood. Patients might present in various ways including chest pain, ST- elevation acute coronary syndrome, ventricular arrhythmia, and sudden cardiac death. Although conservative management is mostly recommended with better outcomes, revascularization should be considered in certain circumstances. In this article, we describe a case series of five patients with SCAD. Additionally, this article reviews clinical presentation, incidence, diagnostic modalities, management and risk of recurrences in patients diagnosed with SCAD.

Independent Risk Factors for Thromboembolic Events in High-Risk Patients With Takotsubo Cardiomyopathy.

Takotsubo cardiomyopathy (TCM) is characteristically associated with left ventricular apical ballooning and regional wall motion abnormalities that predispose to the formation of left ventricular (LV) thrombi and subsequent thromboembolic events (VTE). There is limited data about the risk factors of developing stroke in the absence of LV thrombi in patients with TCM. Identify risk factors that predispose patients with TCM to develop VTE and stroke. We retrospectively reviewed all patients admitted with a primary diagnosis of stress induced or Takotsubo cardiomyopathy at a large tertiary care center from 2005 to 2019. Patients who met the echocardiographic criteria of TCM, had resolution of WMA on repeat echocardiogram, did not have coronary artery disease if angiography was performed and survived for > 3 months after index presentation were included in the analysis. Patients were followed for up to a period of 1 year. Multivariate analysis was performed to identify predictors of thromboembolism. Among the 400 patients who presented with TCM, 146 patients were included in the analysis. A total of 13 patients (8.9%) had documented thromboembolic events. Patients with VTE more often had Atrial fibrillation (30.8% vs 6.8%, P = 0.018), higher LV mass (224.5g vs 184g, P = 0.04), lower EF on presentation (31.5% vs 40%, P = 0.011) and were less likely to have undergone coronary angiography following diagnosis (23.1% vs 54.9%, P = 0.04). On multivariate analysis, atrial fibrillation (OR 9.15, CI 1.15-72.70) and low ejection fraction on admission (OR 0.88, CI 0.81-0.97) were independent risk factors for the development of VTE. Atrial fibrillation and low ejection fraction on presentation were associated with higher risk of developing thromboembolic events in patients with TCM.

Relationship Between Body Mass Index and Outcomes in Acute Myocardial Infarction.

Background: The prevalence of obesity in the United States is high. Obesity is one of the leading risk factors in the development of acute myocardial infarction (AMI). Nevertheless, how obesity impacts AMI in-hospital outcomes remains controversial. Methods: Using National Inpatient Sample (NIS) database, we identified patients diagnosed with AMI from the year 2015 to 2018. We divided these patients into five subgroups based on their body mass index (BMI). We compared outcomes such as mortality, length of inpatient stay, and inpatient complications between our subgroups. Statistical analysis was done using the program STATA. Our nationally representative analysis included 561,535 patients who had an AMI event across various weight classes. Results: Most of our sample was obese (BMI > 30 kg/m2) and male. Obese patients were significantly younger than the rest. Length of stay (LOS) for AMI was highest for those with a BMI of less than 24 kg/m2. In-hospital mortality is highest for those with a BMI of < 30 kg/m2 and lowest for those with a BMI of 30 - 40 kg/m2. Inpatient complications are highest in the lower BMI population (BMI < 24 kg/m2). Conclusion: The current analysis of a nationally representative sample showed the clinical implications of BMI in patients with AMI. Patients with a BMI of 30 - 40 kg/m2 had more favorable LOS, inpatient complications, and in-hospital mortality when compared to those with an ideal body weight. Hence, this supports and expands on the concept of the "obesity paradox". Further studies are needed to further investigate the possible mechanism behind this.

Ortner's syndrome: A rare case of hoarseness secondary to chronic aortic dissection.

Ortner's syndrome, also known as cardiovocal syndrome, is a rare presentation of aortic dissection. Symptoms occur as a result of recurrent laryngeal nerve compression. Our report describes a case of a patient who complained of hoarseness for a few months and was eventually diagnosed with chronic aortic dissection.

Disparities in the Prescription of Statins in the Primary Care Setting: A Retrospective Observational Study.

Despite the high disease burden of atherosclerosis, evidence exists for the disparity in the prescription of guideline-indicated medications between genders, racial groups, socioeconomic groups, and ages. We aim to perform a retrospective study looking at the disparity in statin prescription for primary and secondary prevention in these groups. Data were collected from a single center and included patients with an LDL level >190 mg/dL, diagnosis of diabetes mellitus with LDL level >70 mg/dL, and diagnosis of cardiovascular disease regardless of LDL level. Patients older than 75 or younger than 21 were excluded from the study. Complex samples multivariable logistic and linear regression models were used to calculate the adjusted odds ratio and 95% confidence interval. The total study population was n = 56,995. Of those, 57.89% (n = 32,992) were female. Only 59.56 % of these patients for whom statin therapy was indicated received it. Most patients were White (53.21%) followed by African Americans (35.98%), Asians (2.43%), American Indian/Native Alaskans (0.40%), and Native Hawaiian/Pacific Islander (0.18%). There is a clear disparity in statin prescription favoring males, the elderly, and people of white ethnicity. Interestingly, Asians were more likely to be prescribed statins as opposed to whites. Self-pay patients were more likely to receive statins than patients on Medicare.Despite being indicated, Statins are under prescribed. Disparities based on race, gender, and insurance type mirror previous trends in the literature. Some results have shown a reversal in trends such as the higher prescription for Asian-Americans. Multiple patient-specific, provider-related, institutional factors might explain these disparities and must be investigated.

Cardiac macrophage density in Covid-19 infection: relationship to myocyte necrosis and acute lung injury.

SARS-Cov-2 infection is not limited to the respiratory tract and can involve other organs including the heart, blood vessels, kidneys, liver, gastrointestinal tract, placenta, and skin. Covid-19 patients with cardiac involvement usually have higher morbidity and mortality compared to those without cardiac involvement. The frequency and the specificity of the myocardial pathological changes in patients who die after documented infection with SARS-Cov-2 is uncertain. Macrophages can be found in the normal heart (interstitium, around the endothelial cells and in the epicardial adipose tissue), and they are considered part of the major immune cell population in the heart. In this case-control autopsy study, we compare the gross and microscopic cardiac findings, and the available clinical characteristics between a group of 10 Covid-19 decedents and a control group of 20 patients who died with non-SARS-Cov-2 severe bronchopneumonia and/or diffuse alveolar damage. The objectives of this semi-quantitative study are to study single myocyte necrosis and its relation to the strain on the heart caused by lung injury as a causative mechanism, and to study the density of myocardial and epicardial macrophages in Covid-19 hearts in comparison to the control group, and in Covid-19 hearts with single myocyte necrosis in comparison to Covid-19 hearts without single myocyte necrosis. Lymphocytic myocarditis was not identified in any of the hearts from the Covid-19 or the control group. Single myocyte necrosis is more frequent in the Covid-19 group compared to the control group, suggesting that it is unrelated to the strain on the heart caused by underlying lung injury. The density of the macrophages in the epicardium and myocardium in the hearts of the Covid-19 group is higher compared to those in the control group. The density of epicardial macrophages is higher in the Covid-19 hearts with single myocyte necrosis than in those without. These observations contribute to our increasing appreciation of the role of macrophages in the pathophysiologic response to infection by SARS-CoV-2.

Transfemoral aortic valve replacement in a nonagenarian with aortic stenosis and cardiac amyloidosis: case report.

BACKGROUND: Cardiac amyloidosis (CA) is diagnosed with increasing frequency in the elderly population with severe aortic stenosis (AS), especially with the low-flow, low- gradient phenotype. Prognosis is poor with no treatment. CASE PRESENTATION: The patient is a 94-year-old active male who presented with a stroke that fully resolved. He was found to have low-flow, low-gradient severe AS, along with concomitant CA. Gradients across the aortic valve worsened with the dobutamine challenge test. He underwent successful transfemoral aortic valve replacement (TAVR) and did well postoperatively, where he remained in the hospital for only one day. Treatment of his CA with Tafamidis was recommended; however, the patient declined due to its cost and personal preference. CONCLUSION: To our knowledge, we report on one of the oldest patients to undergo TAVR for low-flow, low-gradient AS with concurrent CA (AS-CA). It might be prudent to screen elderly patients with AS for CA, as prognosis is worse with medical management alone. TAVR has overall improved survival in patients with AS-CA and is considered the procedure of choice, as these patients are typically older and at higher risk for surgical intervention.

Pregnancy-Associated Myocardial Infarction: A Review of Current Practices and Guidelines.

PURPOSE OF REVIEW: Pregnancy-associated myocardial infarction is a principal cause of cardiovascular disease with a steadily rising incidence of 4.98 AMI events/100,000 deliveries over the last four decades in the USA. It is also linked with significant maternal and fetal morbidity and mortality, with maternal case fatality rate ranging from 5.1 to 37%. The management of acute myocardial infarction can be challenging in pregnant patients since treatment modalities and medication use are limited by their safety during pregnancy. RECENT FINDINGS: Limited guidelines exist regarding the management of pregnancy-associated myocardial infarction. Routinely used medications in myocardial infarction including angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), and statin therapy are contraindicated during pregnancy. Aspirin use is considered safe in pregnant women, but dual antiplatelet therapy and therapeutic anticoagulation can be associated with increased risk of maternal and fetal complications, and should only be used after a comprehensive benefit-to-risk assessment. The standard approach to revascularization requires additional caution in pregnant women. Percutaneous coronary intervention is generally considered safe but can be associated with high failure rates and poor outcomes depending on the etiology. Fibrinolytic therapy may have significant sequelae in pregnant patients, and hemodynamic management during surgery is complex and adds risk during pregnancy. Understanding the risks and benefits of the different treatment modalities available and their utility depending on the underlying etiology, encompassed with a multidisciplinary team approach, is vital to improve outcomes and minimize maternal and fetal complications.

Postoperative Myocardial Injury in Patients Classified as Low Risk Preoperatively Is Associated With a Particularly Increased Risk of Long-Term Mortality After Noncardiac Surgery.

Background Prior studies have shown an association between myocardial injury after noncardiac surgery (MINS) and all-cause mortality in patients following noncardiac surgery. However, the association between preoperative risk assessments, Revised Cardiac Risk Index and American College of Surgeons National Surgical Quality Improvement Program, and postoperative troponin elevations and long-term mortality is unknown. Methods and Results A retrospective chart review identified 548 patients who had a troponin I level drawn within 14 days of noncardiac surgery that required an overnight hospital stay. Patients aged 40 to 80 years with at least 2 cardiovascular risk factors were included, while those with trauma, pulmonary embolism, and neurosurgery were excluded. Kaplan-Meier survival and odds ratio (OR) with sensitivity/specificity analysis were performed to assess the association between preoperative risk and postoperative troponin elevation and all-cause mortality at 1 year. Overall, 69%/31% were classified as low-risk/high-risk per the Revised Cardiac Risk Index and 66%/34% per American College of Surgeons National Surgical Quality Improvement Program. Comparing the low-risk versus high-risk groups, preoperative risk assessment was not associated with either postoperative troponin elevation or 1-year mortality. MINS portended a 1-year mortality of OR, 3.9 (95% CI, 2.44-6.33) in the total population. Patients classified as low risk preoperatively with MINS had the highest risk of 1-year mortality (OR, 9.6; 95% CI, 4.27-24.38), with a low prevalence of statin use. Conclusions Current preoperative risk stratification tools do not prognosticate the risk of postoperative troponin elevation and all-cause mortality at 1 year. Interestingly, patients classified as low risk preoperatively with MINS had a markedly higher 1-year mortality risk compared with the general population, and most of them are not taking a statin. Our results suggest that evaluating preoperatively low-risk patients for MINS presents an opportunity for prognostication, risk reclassification, and initiating therapies such as statins to mitigate long-term risk.

Aspiration thrombectomy in ST-Elevation myocardial infarction: Further insights from a network meta-analysis of randomized trials.

BACKGROUND: The initial enthusiasm for thrombectomy during percutaneous coronary intervention (PCI) of ST-elevation myocardial infarction (STEMI) patients has given way to restraint. There has been some limited interest whether it is beneficial in a few selected subgroups. Hence, we performed a network meta-analysis to compare conventional PCI (cPCI), Aspiration or manual thrombectomy (AT) and Mechanical thrombectomy (McT) for clarification. METHODS: Electronic databases were searched for randomized studies that compared AT, McT, or cPCI. A network meta-analysis was performed and odd's ratio (OR) with 95% confidence intervals was generated for major adverse cardiac events (MACE), mortality, myocardial infarction (MI), target vessel revascularization (TVR), stent thrombosis (ST), stroke, left ventricular ejection fraction (LVEF), myocardial blush grade (MBG) and ST segment resolution (STR). RESULTS: A total of 43 randomized trials (n = 26,682) were included. The risk of MACE (OR 0.86 95% CI 0.73-1.00), Mortality (OR 0.85 95% CI 0.73-0.99), MI (OR 0.65, 95% CI: 0.44-0.95) and TVR (OR 0.86, 95% CI: 0.74-1.00) were lower with AT compared to cPCI. The risk of ST and stroke was no different with the use of adjunctive AT. MBG, STR, and LVEF improved with the use of AT while the infarct size was no different in the two groups. CONCLUSIONS: Our comprehensive network meta-analysis suggests conflicting outcomes with AT. While Mortality, MACE, MI seem better, there is a suggestion that, Stroke and ST might be worse. Whether AT can still be pursued in any select cases should be further scrutinized.

Serum Bilirubin and Coronary Artery Disease: Intricate Relationship, Pathophysiology, and Recent Evidence.

Coronary artery disease (CAD) is a major cause of morbidity, mortality, and healthcare expenditure. A number of environmental and genetic risk factors have been known to contribute to CAD. More recently, a number of studies have supported as well as opposed a possible protective benefit of bilirubin in CAD, since it has anti-inflammatory, antioxidant, and antiaggregatory properties that may reduce atherogenesis. It also shares associations with different forms of CAD, namely stable CAD, unstable angina pectoris, stable angina pectoris, and acute myocardial infarction. Lack of sufficient evidence, however, has failed to elucidate a causal relationship between serum bilirubin level and risk of CAD. Therefore, in this update, we attempted to simplify this intricate relationship between bilirubin and CAD, revisit the pathophysiology of disease, how bilirubin may be protective, and to summarize the findings of the current literature.

Canakinumab: Promises and Future in Cardiometabolic Diseases and Malignancy.

Inflammation has proven in multiple studies to be responsible for the progression of cardiometabolic diseases and malignancies. The interleukin family has been critically associated with progression of atherosclerosis, insulin resistance, and various malignancies. Given the advent of pharmacologic interleukin-1 (IL-1) inhibition, this pathway can potentially be targeted to improve outcomes. In the recently concluded Canakinumab Anti-inflammatory Thrombosis Outcomes Study (CANTOS) trial, investigators looked at the potential role of IL-1 (especially IL-1ß) inhibition in halting the progression of atherosclerosis. In the subset analysis of the data from this trial, IL-1ß inhibition with canakinumab was found to have beneficial effects in other cardiometabolic diseases characterized by inflammation, like diabetes, stroke, and chronic kidney disease, and also in patients with lung cancer. In this article, we will try to review the current literature on the role of canakinumab in the treatment of cardiometabolic diseases and malignancies.
