Emerging Trends in Atherosclerosis: Time to Address Atherosclerosis From a Younger Age

Over the past two decades, research efforts into cardiovascular disease (CVD) have uncovered findings that fundamentally challenge our understanding of CVD, particularly atherosclerosis. Atherosclerosis was primarily attributed to the well-described abnormal lipid accumulation theory, involving plaque growth with subsequent plaque hemorrhage resulting in acute vessel thrombosis that may or may not rupture. This perspective has now evolved to encompass more complex pathways, wherein the accumulation of abnormal products of oxidation and inflammation is the most likely factor mediating atherosclerotic plaque growth. Furthermore, atherosclerosis was traditionally thought of as a disease in patients aged 40 and older. However, mounting evidence has demonstrated that significant atherosclerosis and CVD events are more prevalent in younger patients than previously realized and accelerating in incidence. With this alarming trend among younger individuals, our review sought to explore why this trend may be happening and what can be done about this developing problem.

Obesity-Induced Hyperglycemia and Heart Failure Preserved Ejection Fraction: Uncharted Territories to Remission

Until the end of World War II, food security was a global challenge. Consequently, in 1948, type 2 diabetes was relatively uncommon, with the majority of cases being type 1 diabetes requiring insulin therapy. Since then, food has become increasingly palatable and readily available, leading to a rise in obesity across all age groups. Understanding the impact of obesity on our health has become crucial for optimizing healthcare. In this context, we draw attention to two significant, yet relatively uncharted pathogenic effects associated with obesity: Hyperglycemia and Heart Failure with Preserved Ejection Fraction (HFpEF). Thorough pathophysiologic, hemodynamic, and echocardiographic characterization have revealed the existence of a distinct phenotype known as "obese HFpEF" within the broader HFpEF population, and "obesity-induced hyperglycemia" within the diabetes population. In these phenotypes, patients often present with higher Body Mass Index and experience clinical symptoms decades earlier. Recent insights have enhanced our understanding of the mechanisms underlying obesity-mediated heart failure preserved ejection fraction and hyperglycemia. Early detection offers the potential for reversibility of many pathologies associated with obesity through adequate weight reduction. The objective of this review is to provide a deeper insight into these uncharted territories and explore the potential for improved outcomes by reframing these two narratives toward achieving remission. Such a shift has the potential to positively impact individual engagement with healthier lifestyles.

Our Hidden Enemy: Ultra-Processed Foods, Inflammation, and the Battle for Heart Health

Over the past few decades, we have witnessed unprecedented growth in new data that has fundamentally changed our traditional understanding of the progression of atherosclerotic plaques, as well as our strategies for preventing cardiovascular diseases, especially atherosclerosis. It was once believed that atherosclerosis was primarily caused by abnormal lipid buildup in the vessel intima, leading to plaque growth and luminal stenosis, with or without rupture. This perspective has now evolved to encompass more complex pathways, wherein the accumulation of abnormal products of oxidation and inflammation are the most likely factors mediating the growth of atherosclerotic plaques. The review aims to provide a comprehensive and detailed exploration of the relationship between ultra-processed foods, chronic inflammation, cardiovascular diseases, obesity, insulin resistance, and the role of the gut microbiota. It touches on several important aspects of modern diet and health.

Role of Cardiac Biomarkers in Monitoring Cardiotoxicity in Chemotherapy Patients

PURPOSE

This review aims to highlight the different types of chemotherapy-induced cardiotoxicity and will discuss the evidence base behind the use of different cardiac biomarkers to predict cardiovascular complications. Additionally, we will review the use of cardiac biomarkers to monitor cardiac outcomes and the role of cardioprotective medications in reducing cardiovascular side effects.

RECENT FINDINGS

Chemotherapy has been linked to an increased risk of cardiotoxicity and heart failure. Currently, patients receiving chemotherapy undergo echocardiogram before starting chemotherapy and every 6 months to monitor for any decline in cardiac function. We reviewed the current evidence and practice guidelines of monitoring chemotherapy cardiotoxicity.

SUMMARY

Cardio-oncology is a rapidly evolving subspecialty in cardiology, especially with the advent of new chemotherapeutic agents, which have cardiovascular side effects. Early detection of these effects is crucial to prevent life-threatening and irreversible cardiovascular outcomes. Monitoring troponin, pro-brain natriuretic peptide, and other cardiac biomarkers during chemotherapy will help to early detect cardiotoxicity.

Growth Differentiation Factor 15 (GDF-15), a New Biomarker in Heart Failure Management

The emergence of biomarkers across medicine's subspecialties continues to evolve. In essence, a biomarker is a biological observation that clearly substitutes a clinical endpoint or intermediate outcome not only are more difficult to observe but also, biomarkers are easier, less expensive and could be measured over shorter periods. In general, biomarkers are versatile and not only used for disease screening and diagnosis but, most importantly, for disease characterization, monitoring, and determination of prognosis as well as individualized therapeutic responses. Obviously, heart failure (HF) is no exception to the use of biomarkers. Currently, natriuretic peptides are the most used biomarkers for both diagnosis and prognostication, while their role in the monitoring of treatment is still debatable. Although several other new biomarkers are currently under investigation regarding diagnosis and determination of prognosis, none of them are specific for HF, and none are recommended for routine clinical use at present. However, among these emerging biomarkers, we would like to highlight the potential for growth differentiation factor (GDF)-15 as a plausible new biomarker that could be helpful in providing prognostic information regarding HF morbidity and mortality.

Heart Failure with Preserved Left Ventricular Ejection Fraction: A Complex Conundrum Simply Not Limited to Diastolic Dysfunction

Over the last two decades, the changing paradigm of heart failure with preserved ejection fraction (HFpEF) has transformed our understanding not only of the pathophysiology of this clinical entity but also the diagnostic and therapeutic approaches aimed at treating this complex patient population. No longer HFpEF should be seen as simply left ventricular diastolic dysfunction but as a group of that in addition of having small and thick left ventricles with abnormal diastolic filling patterns as their main pathophysiologic abnormality; they also have whole host of different abnormalities. In fact, this heterogeneous clinical entity embodies numerous mechanisms and is linked to multiorgan dysfunction, with hypertension and obesity playing a major role. Although we have gained an enormous amount of understanding not only on the causes but also the downstream effects of HFpEF, there is still much to be learned before we can fully comprehend this complex clinical entity. It is the main intention of this review to synthesize the most recent attributes, mechanism, diagnostic tools, and most useful therapeutic alternatives to be considered when evaluating patients either complaining of dyspnea on exertion as well as exercise intolerance or those recently admitted with HF symptoms but with normal LVEF in the absence of any other valvular abnormalities.

National Trends of Percutaneous Mechanical Support Utilization During Percutaneous Coronary Interventions in Chronic Total Occlusion

Coronary chronic total occlusion (CTO) is common in patients with multivessel coronary artery disease. Percutaneous coronary artery (PCI) interventions have shown favorable outcomes in patients with CTO. Nevertheless, the data regarding the utilization of mechanical circulatory support in CTO PCIs is not well established. We sought to investigate the trends in utilization and periprocedural complications in this population. Using the National Inpatient Sample database from 2011 to 2019, we identified patients diagnosed with CTO who underwent PCI. We investigated the presence of a linear trend in the utilization of mechanical circulatory support (MCS) during those procedures and the associated periprocedural complications using the Cochran-Armitage method. A total of 208,123 patients who were diagnosed with CTO and underwent PCI from 2011 to 2019, of which in 6,319 patients MCS was used during the procedure. Patients in the MCS group were older (67.4 vs 66.4 years), less likely to be women (24.0% vs 26.4%), and equally likely to be African-American (9.4% vs 8.8%) with a higher burden of co-morbidities in terms of coronary artery disease, congestive heart failure, and atrial fibrillation (p <0.001 for all). Using the Cochrane-Armitage method, we found a statistically significant linear uptrend in the utilization of MCS from 269 (1.4%) to 990 cases (7.0%) from 2011 to 2019. Using multivariable logistic regression, female gender, renal failure, alcohol abuse, coagulopathy, and fluid and electrolyte disorders were identified as independent predictors of mortality in CTO PCI procedures assisted with MCS (p ≤0.007). In conclusion, the utilization of MCS in CTO PCI procedures has been increasing over the years. Female gender and renal failure are independently associated with a higher mortality risk.

Early repolarization: Electrocardiographic cues to distinguish benign from malignant variants

Historically, early repolarization (ER) has been considered a marker of good health as it is more prevalent in athletes, younger persons, and at slower heart rates. However, contemporary reports, largely based on data from resuscitated sudden cardiac arrest patients, suggest an association between ER and an increased risk for sudden cardiac death and the development of malignant ventricular arrhythmias. Therefore, after we present a brief-case presentation, we intend to review a challenging topic in recognition of malignant variants and propose a four-step comprehensive approach to simplify ECG discrimination when assessing ER changes.

Epigenetic Regulation and its Effects on Aging and Cardiovascular Disease

Cardiovascular disease (CVD), specifically coronary atherosclerosis, is regulated by an interplay between genetic and lifestyle factors. Most recently, a factor getting much attention is the role epigenetics play in atherosclerosis; particularly the development of coronary artery disease. Furthermore, it is important to understand the intricate interaction between the environment and each individual genetic material and how this interaction affects gene expression and consequently influences the development of atherosclerosis. Our main goal is to discuss epigenetic regulations; particularly, the factors contributing to coronary atherosclerosis and their role in aging and longevity. We reviewed the current literature and provided a simplified yet structured and reasonable appraisal of this topic. This role has also been recently linked to longevity and aging. Epigenetic regulations (modifications) whether through histone modifications or DNA or RNA methylation have been shown to be regulated by environmental factors such as social stress, smoking, chemical contaminants, and diet. These sensitive interactions are further aggravated by racial health disparities that ultimately impact cardiovascular disease outcomes through epigenetic interactions. Certainly, limiting our exposure to such causative events at younger ages seems our "golden opportunity" to tackle the incidence of coronary atherosclerosis and probably the answer to longevity.

Profiling Cardiometabolic Health in Jordan: A Call to Action to Improve Cardiovascular Health

Over the past decades, Jordan has witnessed unprecedented growth in the prevalence of cardiometabolic diseases, with a crude prevalence of 48.2% in 2020, up from 38% in 2009. This is slightly higher than the reported prevalence of 40% in the US population. According to the latest World Health Organization report published in 2020, Jordan's leading cause of mortality is cardiovascular diseases with a cause-specific mortality rate of 18.6%. Since the advancement of the healthcare system in Jordan took place in the early 2000s, Jordan has witnessed a major epidemiologic transition where the burden of infectious disease has decreased, but on the other hand, the burden of cardiometabolic disease has increased as well. For such a country with limited resources and healthcare infrastructure where two-thirds of its population is below the age of 30, this is alarming. This growth can be attributed to a complex interplay between genetic and lifestyle factors. Smoking, physical inactivity, obesity, and unhealthy diet are considered major public health problems in Jordan, as reported in 2007 by the Jordanian Behavioral Risk Factor Surveillance. We attempt to raise awareness through this review article, so healthcare providers in Jordan understand the magnitude of the issue, and appropriate steps are taken to reestablish screening and management guidelines pertaining to cardiometabolic diseases in Jordan.

Improving diagnostic assessments in the ever-changing landscape of atherosclerosis

As our understanding of atherosclerotic vascular injury continues to evolve, so should our diagnostic approaches. Emerging data have recently challenged our basic understanding in linking ischemia to its adverse outcomes as well as the need for invasive testing for both diagnosis and treatment. The advent of coronary computed tomography in providing improved visualization of coronary arteries has led to the identification of both subclinical atherosclerosis and high-risk coronary lesions. Recognition of asymptomatic coronary artery disease (CAD) with objective localization of subclinical coronary atherosclerosis improves atherosclerotic cardiovascular risk assessment and allows healthcare providers to take effective primary prevention measures. Therefore, reshaping the diagnostic landscape in proposing new testing modalities would be highly dependent on local resource availability and the reading expertise of each clinical practice and medical institution. The main objective of this Review is to propose a potentially new diagnostic approach of simply using noninvasive stress testing or coronary angiography in the routine assessment of CAD.

Same-Day Discharge After Left Bundle Area Pacing

BACKGROUND

Left bundle area pacing (LBAP) has emerged as an area that appears to be an attractive alternative to other forms of physiological pacing owing to its ease and favorable pacing parameters. Same-day discharge after conventional pacemakers, implantable cardioverter defibrillators, and more recently leadless pacemakers have become routine, especially after the COVID-19 pandemic. With the advent of LBAP, the safety and feasibility of same-day discharge remain unclear.

METHODS

This is a retrospective, observational case series of consecutive, sequential patients undergoing LBAP at Baystate Medical Center, an academic teaching hospital. We included all patients who underwent LBAP and were discharged on the same day of procedure completion. Safety parameters included any procedure-related complications including pneumothorax, cardiac tamponade, septal perforation, and lead dislodgement. Pacemaker parameters included pacing threshold, R-wave amplitude, and lead impedance pre-discharge the following day of implantation and up to 6 months of follow-up.

RESULTS

A total of 11 patients were included in our analysis, the average age was 70.3 ± 6.74 years. The most common indication for pacemaker insertion was AV block (73%). No complications were seen in any of the patients. The average time between the procedure and discharge was 5.6 hours. Pacemaker and lead parameters were stable after 6 months of follow-up.

CONCLUSIONS

In this case series, we find that same-day discharge after LBAP for any indication is a safe and feasible option. As this mode of pacing becomes increasingly more common, larger prospective studies evaluating the safety and feasibility of early discharge after LBAP will be needed.

Vasospastic Angina With ST-Segment Elevation Seen During Mobile Cardiac Outpatient Telemetry (MCOT) Monitoring

A 54-year-old man presented with significant ST-segment elevations noted on both channels displayed on the mobile cardiac outpatient telemetry (MCOT). Pertinent cardiac history was remarkable for syncope and episodes of atypical chest pain. The latter were described as infrequent and not associated with exercise intolerance. His syncopal episodes were described as occurring mostly in the mornings after the use of the restroom. Episodes happen 1 or 2 times a year since 2015. Patient had undergone thorough investigation with no significant findings. An MCOT was prescribed since frequency of symptoms has recently increased. Significant ST-segment elevations were noted. The patient described atypical chest pain and a sensation of presyncope during these recordings. He was urgently admitted, and a coronary angiogram revealed no epicardial luminal stenosis. However, the presence of sluggish coronary flow was suggestive of possible vasospastic angina. No ST-segment changes were noted during his coronary angiogram. The remarkable element portrayed by this case hinges in showing the unique utility of MCOT, as the most uncharacteristic diagnostic tool, in identifying transient ST-segment elevations that finally led to the diagnosis.

Relation of Patient's Opinion of Alcohol's Health Effects and Drinking Habits Among Hospitalized Patients With Cardiovascular Disease

Media reports frequently cite observational studies and meta-analyses to promote the reputed cardiovascular benefits of moderate alcohol consumption; however, it is unclear whether public opinion or drinking behavior align with these reports. We administered an anonymous, single-center, 35-question, cross-sectional survey among patients hospitalized for acute cardiac illnesses from June to September 2019, who were eligible for cardiac rehabilitation. We assessed patient opinions toward alcohol use, perceptions of alcohol's health impact, and role of media in forming these beliefs. We hypothesized that drinking habits are associated with beliefs about the health benefits of alcohol consumption. Of 300 patients approached, 290 completed the survey (97%). Most (69%) reported having heard moderate alcohol use is heart healthy from 1 or more sources including: TV (61%), family/friends (33%), newspapers (21%), and the internet (10%); although, only 19% reported believing these reports. In total, 12 patients (4%) reported intentionally increasing alcohol intake because of the reported beneficial health effects. There was a strong association between binge drinking and increasing alcohol used to improve cardiac health (odds ratio 8.8, 95% confidence interval 2.7, 29). Given the known cardiotoxic effects of alcohol, particularly in large doses, strategies aimed at population-based education regarding the unhealthy cardiovascular impact of alcohol use is needed, especially among binge drinkers.

Cardiovascular Predictors of Intracerebral Hematoma Expansion

BACKGROUND

There is limited evidence on the effect and relevance of cardiovascular parameters on the cerebrovascular system when an intracerebral hemorrhage (ICH) occurs. While recent studies evaluating this relationship are conflicting, one evaluating the effect of systolic cardiac function on clinical outcomes in ICH patients, found low cardiac ejection fractions to be associated with poor clinical outcomes. Our primary objective was to study such correlations and identify various cardiovascular disease states that may be associated with hematoma expansion.

METHODS

This is an IRB-approved single-center retrospective study utilizing our institutional "Get with the Guidelines"-Stroke registry between 2013 and 2017. Patients included were older than 18 years of age, admitted with an acute ICH, and had an echocardiogram during their hospitalization. Univariate and multivariate logistical regression analyses were used to identify cardiovascular predictors of hematoma expansion.

RESULTS

Two-hundred forty-nine patients were identified from our GWTG-S registry that met initial inclusion criteria. Of these patients, a history of peripheral arterial disease (PAD) (p = 0.015), presence of aortic stenosis (AS) on the echocardiogram (p = 0.025), and a positive spot sign on the CT-angiogram (CTA) of the head (p < 0.001) were found to be independently associated with ICH expansion. Both a history of hypertension and elevated blood pressure on presentation were not significant predictors. Additionally, patients with a history of congestive heart failure had decreased odds of hematoma expansion (p = 0.027).

CONCLUSION

This exploratory study highlights potential novel cardiac predictors of hematoma expansion, including PAD and AS, which warrant further study. Larger prospective studies are needed to further investigate such associations to ultimately optimize cardio-cerebral health.

COVID-19: The Impact on Internal Medicine Resident Training

The novel coronavirus disease 2019 (COVID-19) pandemic has impacted the lives of physicians at all levels. The workloads and working hours have increased tremendously which affected the time spent on administrative and academic duties. The COVID-19 pandemic imposed a lot of challenges on academic institutions in term of providing quality of care to patients and maintaining the quality of education for trainee. Herein, we discuss the challenges and impact of the pandemic on residents training.

In-hospital outcomes of transcatheter versus surgical mitral valve repair in patients with chronic liver disease

BACKGROUND

Mitral valve transcatheter edge-to-edge repair (TEER) using MitraClip is a treatment option for patients with moderate to severe mitral regurgitation who are not surgical candidate. Liver cirrhosis is associated with higher operative morbidity and mortality; however, it is not part of preoperative risk assessments calculators. We sought to evaluate the in-hospital outcomes in TEER and surgical mitral valve repair (SMVR) in liver cirrhosis.

METHODS

National Inpatient Database from 2013 to 2017 was used to obtain all patients with cirrhosis who underwent TEER or SMVR using ICD-9-CM and ICD-10-CM codes. The primary outcome is to compare inpatient mortality between TEER and SMVR. Secondary outcomes were assessed including length of stay (LOS) and rate of complications including cardiogenic shock, blood transfusion and prolonged ventilation.

RESULTS

A total of 875 patients with cirrhosis who underwent TEER (n = 123) or SMVR (n = 752) were identified in our analysis. Patients with TEER had significantly higher comorbidities such as congestive heart failure, coronary artery disease and chronic obstructive pulmonary disease. In-hospital mortality was lower in TEER group (8.2% vs 16%, P = .04). TEER was associated with lower rates of blood transfusion (30.3% vs 61.2%, P = .02) and reduced rates of prolonged mechanical ventilation (1.2% vs 17.2%, P = .042). In multivariate regression analysis, both blood transfusion and prolonged mechanical ventilation were significant predictors of mortality in liver cirrhosis.

CONCLUSIONS

TEER was associated with lower rate of in-hospital mortality, LOS, blood transfusion and prolonged mechanical ventilation in cirrhosis patients. TEER can be considered as a viable option for cirrhosis patient with severe mitral regurgitation.

Oh wait … It isn't MUDPILES! Acute toxic encephalopathy with an interesting anion gap metabolic acidosis resulting in prolonged invasive mechanical ventilation

A 70-year-old white female patient with past medical history of migraine, fibromyalgia, diverticulitis, and hypothyroidism presented to the emergency department accompanied by her husband for one day of altered mentation, nausea and vomiting. Laboratory testing showed oligo-anuric acute kidney injury with a severely high anion gap metabolic acidosis. Urine drug screen was negative. Brain imaging and lumbar puncture were negative for acute findings. We report this unique case by going through the differential for anion gap metabolic acidosis secondary to Celecoxib as well as a unique drug–drug interaction between Celecoxib and Gabapentin.

Frequency of Hazardous and Binge Drinking Alcohol Among Hospitalized Cardiovascular Patients

Excessive alcohol use is a risk factor for most cardiac diseases. The prevalence of unhealthy alcohol use among hospitalized cardiac patients is uncertain as is the frequency with which it is addressed. We performed a single center, patient-level anonymous survey among hospitalized cardiac patients eligible for cardiac rehabilitation. Hazardous drinking was defined as an Alcohol Use Disorders Identification Test (AUDIT) score of 8 or greater. Binge drinking was defined as 5+ drinks for men or 4+ for women on ≥1 occasion within the past 30 days. Unhealthy drinking was defined as either hazardous or binge drinking. Of 300 patients approached, 290 (96.7%) completed the survey. Mean ( ± SD) age was 69 ± 11 years; 70% were male and 31% were cardiac surgical patients. The proportion (95% CI) of hazardous, binge, and unhealthy drinking was 12% (9 to 16), 16% (12 to 20), and 18% (14-23), respectively. Overall, 58% of subjects reported being screened for alcohol use, mostly by nurses (56%). Those with unhealthy drinking reported being counseled more frequently about their alcohol use compared to non-unhealthy drinkers (11% versus 3%, p = 0.03), but the large majority (89%) of unhealthy drinkers reported receiving no advice about their alcohol use while admitted. In conclusion, almost one-fifth of hospitalized cardiac patients reported unhealthy drinking, these patients were only screened about half of the time, and were rarely counseled about their alcohol use.

It Is Just a Rash They Said! Acute Skin Manifestation in a Patient With Vasculitis in Rural Hospitals

A 76-year-old Caucasian male with a history of rheumatoid arthritis, Raynaud’s phenomenon, pulmonary embolism on warfarin, and a previous amputation of his left partial ring and fifth finger presented with acute onset of rash in bilateral lower extremities. He was recently started on trimethoprim-sulfamethoxazole due to concern for cellulitis. Differential diagnosis for acute-onset rash with the patient’s history presented as a challenge to the internist, as the differential is broad. Our case goes through the differential diagnosis to contrast the different presentations of rash in a patient with vasculitis. Ultimately skin biopsy in conjunction with a past positive cryoglobulinemic level helped confirm the diagnosis of cutaneous vasculitis, following which he was started on appropriate treatment and recovered.

Outcomes of cardiogenic shock with autoimmune rheumatological disorders

AIMS

Data on cardiogenic shock (CS) in autoimmune diseases (AID) is limited. Our study aims to evaluate in-hospital outcomes of CS in hospitalized patients with underlying AID compared with patients without AID.

METHODS

The National Inpatient Sample (NIS) database years 2011-17 was used to identify hospitalizations for CS. We retrospectively compared in-hospital outcomes of CS in patients with underlying AID versus non-AID.

RESULTS

Of 863,239 patients diagnosed with CS, 23,127 (2.7%) had underlying AID. The AID population was older with more women and African American patients (P < 0.001 for all). There was a significant increase in in-hospital mortality in patients with AID vs non-AID that persisted after adjustment for demographics, comorbidities, insurance, socioeconomic status and hospital characteristics (38.3% vs 36.3%, aOR 1.06; 95% CI: 1.02-1.09, P = 0.001). Patients with AID had a lower rate of respiratory complications (11.5% vs 13.1%), acute stroke (6.0% vs 6.8%), use of mechanical circulatory support (12.0% vs 14.5%) and discharge to an outside facility (29.1% vs 28.8%) (P ≤ 0.001 for all). Using multivariable logistic regression, we identified female gender, Native American ethnicity, heart failure, coagulopathy, pulmonary circulation disorders, metastatic cancer, and fluid and electrolytes disorders as independent predictors of mortality in patients with AID who were diagnosed with CS.

CONCLUSION

Patients with AID hospitalized with CS have increased mortality which may be related to their underlying disease process and lack of effective disease-directed therapy for CS related to AID.

Iatrogenic Right Atrial Thrombus Complicated by Pulmonary Embolism: Management and Outcomes

Right atrial thrombus can originate from distal venous sources or can be iatrogenic, secondary to the placement of central venous catheters, atrial devices, or surgeries. One of the most common complications of Central Venous Catheters (CVCs) is thromboembolism, which can be either fixed to the right atrium or can be free-floating. Device-related Right Atrial Thrombosis (RAT) can result in catheter occlusion, vascular occlusion, infection, and pulmonary embolism. The true incidence of these complications is unknown because the diagnosis may not be considered in asymptomatic patients, and it might be missed by Transthoracic Echocardiography (TTE). In this literature review, we discuss iatrogenic etiologies of RAT that is complicated by pulmonary embolism. We highlight the importance of maintaining a high index of suspicion of iatrogenic RAT, possible complications, and its management.

Spontaneous Biliary Pericardial Tamponade: A Case Report and Literature Review

BACKGROUND

Biliary pericardial tamponade (BPT) is a rare form of pericardial tamponade, characterized by yellowish-greenish pericardial fluid upon pericardiocentesis. Historically, BPT reported to occur in the setting of an associated pericardiobiliary fistula. However, BPT in the absence of a detectable fistula is extremely rare.

LEARNING OBJECTIVE

A biliary pericardial tamponade is a rare form of tamponade warranting a prompt workup (e.g., MRCP or HIDA scan) for a potential fistula between the biliary system and the pericardial space. A pericardio-biliary fistula can be iatrogenic or traumatic. People with a history of chest wall trauma, abdominal surgery, or chest surgery are at increased risk. The use of HIDA scanning plays a salient role in effectively surveilling for the presence of a fistula - especially when MRCP is contraindicated.

CASE PRESENTATION

A 75-year-old Hispanic male presenting with dyspnea and diagnosed with cardiac tamponade is the subject of the study. Subsequent pericardiocentesis revealed biliary pericardial fluid (bilirubin of 7.6 mg/dl). The patient underwent extensive workup to identify a potential fistula between the hepatobiliary system and the pericardial space, which was non-revealing. The mechanism of bile entry into the pericardial space remains to be unidentified.

LITERATURE REVIEW

A total of six previously published BPT were identified: all were males, with a mean age of 53.3 years (range: 31-73). Mortality was reported in two out of the six cases. The underlying etiology for pericardial tamponade varied across the cases: incidental pericardio-biliary fistula, traumatic pericardial injury, and presence of associated malignancy. - Conclusion: Biliary pericardial tamponade is a rare form of tamponade that warrants a prompt workup (e.g., Hepatobiliary Iminodiacetic Acid - HIDA scan) for an iatrogenic vs. traumatic pericardio- biliary fistula. As a first case in the literature, our case exhibits a biliary tamponade in the absence of an identifiable fistula.

Is the thrombolysis in myocardial infarction (TIMI) score a reliable source in a rural hospital for the management of unstable angina/non-ST elevated myocardial infarctions (UA/NSTEMI)?

Background: The Thrombolysis in Myocardial Infarction (TIMI) score is considered a method for early risk stratification in patients with unstable angina/non-ST elevated myocardial infarctions (UA/NSTEMI). It is composed of seven factors and if present, each factor contributes a value of one point toward the TIMI risk score, making it a simple tool that does not require differential weights for each factor. A higher score implies a higher likelihood of adverse cardiac events and/or risk of mortality. A TIMI risk score ≥3 recommends early invasive management with cardiac angiography and revascularization. As per CDC study in 2014, Americans living in rural areas are more likely to die from leading causes such as cardiovascular diseases. An estimated number 25,000 deaths than their urban counterparts, which coincide with a TIMI risk score of ≥3, potentially limit the utility of the TIMI risk score in risk stratification in rural catherization laboratories. The objective of this study was to assess the reliability of TIMI score as early risk stratification in patients with unstable angina/non-ST elevated myocardial infarctions (UA/NSTEMI) in rural hospital.

Methods: A retrospective chart review study in a rural hospital was conducted for subjects that received left heart catheterizations, exercise stress tests, or chemical stress tests for a diagnosis of UA/NSTEMI. A total of 399 subjects who underwent left heart catheterization and/or stress testing were recruited for this study. A total of 153 subjects who were transferred out to a larger facility, transitioned to comfort care, refused intervention, or passed away were excluded from the study. The 246 remaining subjects were classified into two groups, those with TIMI 0–2 compared with those having TIMI ≥ 3. A null hypothesis was postulated that there was no significant difference between the two groups with regard to prevalence of either positive stress test or evidence of obstructive coronary disease following coronary angiography. T-test and Wilcoxon rank-sum analysis were performed through SPSS statistical analysis.

Results: Formal statistical analysis using T-test as well as Wilcoxon rank-sum test comparing the two groups showed p = 0.34 for T-test and p = 0.60 for Wilcoxon rank-sum test. This is consistent with the postulated null hypothesis: that there is no significant difference between the two surgery groups with respect to the mean/median TIMI score.

Conclusion: There was no statistical difference between high and low TIMI score in the intervention of unstable angina/non-ST elevated myocardial infarctions (UA/NSTEMI) in a rural hospital.

A Rare Cause of Drug-Induced Pancytopenia: Trimethoprim-Sulfamethoxazole-Induced Pancytopenia

Pancytopenia is a decrease across cellular hematological lines. Many different etiologies can cause this clinical picture including viral and bacterial infections, chemicals, malignancy, and medications. Particular attention should be paid to the onset, timing, and severity as they can indicate the underlying cause. In cases of iatrogenic-induced pancytopenia, the offending agent should be stopped immediately and the patient should be monitored for recovery of cell lines. While not well reported in the literature, trimethoprim-sulfamethoxazole (TMP-SMX) is a cause of pancytopenia. We present a case of drug-induced pancytopenia secondary to TMP-SMX that resolved quickly with cessation of use.

Theophylline in Treatment of COVID-19 Induced Sinus Bradycardia

This is a retrospective case series of two patients with laboratory-confirmed coronavirus 2 (SARS-CoV-2) infection, presented to the University of Arkansas for Medical Sciences in January 2021. Medical records of these patients were reviewed using the EPIC electronic health record system. Clinical, laboratory, and treatment data were reviewed against periods of bradycardia in each patient. Both of the patients presented with dizziness and presyncope related to sinus bradycardia in which they received treatment with 1 mg of IV atropine and theophylline 200 mg orally. We share these two cases of theophylline treatment in COVID-19 induced sinus bradycardia. The first patient was a 39-year-old female, with a past medical history of polycystic ovarian syndrome, who presented to the emergency department with lightheadedness and dizziness. Two weeks prior to her presentation, she was tested positive for COVID-19 infection that was treated with azithromycin, dexamethasone and aspirin. Upon presentation, her ECG showed sinus bradycardia at a rate of 48 bpm. The second patient, a 21-year-old female with no significant past medical history, presented with presyncope. Three weeks prior to her presentation, she tested positive for COVID-19 infection that was treated symptomatically at her home. Upon presentation, her ECG showed junctional rhythm at a heart rate of 51 bpm.

Doubly Blinded: An Uncommon Cause of Acute Visual Loss Due to Orbital Compartment Syndrome

A 68-year-old female patient with a past medical history of atrial fibrillation on anticoagulation regimen with Apixaban and Clopidogrel presented for her scheduled Watchman device implantation. The device was indicated as patient was high risk for falling. Successful implantation of the left atrial appendage device was carried out, and the patient was sent to the floor. One hour after the procedure, the patient started having left-sided diplopia along with severe eye pain. An immediate CT scan of the head showed left superior orbital mass, concerning for hematoma. Urgent left canthotomy with cantholysis was conducted bedside. However, despite early interventions, the patient’s vision was lost.

Extremely high high-density lipoprotein cholesterol with coronary artery disease: Case report

Whether this extremely high high-density lipoprotein (HDL) level due to chronic alcohol abuse or cholesteryl ester transfer protein or others, we report this interesting case of extremely high high-density lipoprotein to emphasize that serum HDL is not always protective from development of coronary heart disease.

The Efficacy of Intravenous Insulin Infusion in the Management of Hypertriglyceridemia-Induced Pancreatitis in a Rural Community Hospital

A 28-year-old female presented to the emergency room with epigastric pain, nausea, and vomiting; her lipase was elevated, and computed tomography of abdomen showed evidence of acute pancreatitis. Her past medical history was significant for poorly controlled insulin requiring type 2 diabetes mellitus and 2 previous admissions for hypertriglyceridemia-induced pancreatitis. Due to the severity of her pancreatitis presentation, she was admitted to the intensive care unit. She received aggressive intravenous fluid hydration and was started on an insulin drip. Apheresis was strongly considered given the degree of her hypertriglyceridemia (11 602 mg/dL), but there was no timely access to this treatment option. She, however, significantly improved with insulin therapy alone. Her triglyceride levels decreased rather quickly to 4783 mg/dL within 24 hours and by the fourth day of admission were comfortably <1000 mg/dL with insulin infusion along with clinical improvement. She was discharged on niacin and insulin therapy along with her home medications of statin and fenofibrate.

The Association Between Body Mass Index, Frailty and Long-Term Clinical Outcomes in Hospitalized Older Adults

BACKGROUND

While frailty is thought to be a wasting disorder, there is scarce data regarding the association between frailty and body mass index (BMI). The aim of this study was to determine the relationship between BMI, frailty, and mortality among hospitalized older adults.

METHODS

This is a secondary analysis of a prospective cohort study of patients aged ≥65 years admitted to a tertiary center between 2014 and 2016. Frailty was assessed by Reported Edmonton Frailty Scale (REFS) and categorized as: not frail, vulnerable/mild frail, and moderate/severe frail. BMI (kg/m2) was categorized as: underweight (<18.5), normal (18.5-24.9), overweight (25.0- 29.9), or obese (≥ 30.0). Primary outcome was all-cause one-year mortality.

RESULTS

Among 769 patients included in the study, 55.4% were frail. There was no statistically significant association between frailty categories and levels of BMI. Frail patients had a higher risk of death than non-frail after adjusting for confounders [HR: 1.98, 95% CI (1.46, 2.70) for mild frail and HR 2.03, 95% CI (1.43, 2.87) for moderate/severe frail]. Compared with normal weight patients, those who were overweight had a survival advantage if they were non-frail [HR 0.55, 95% CI (0.31, 0.96)] or vulnerable/mild frail [HR 0.65, 95% CI (0.43, 0.97)] but not if they were moderate/severe frail. There were no other statistically significant differences in survival by BMI and frailty categories.

CONCLUSIONS

We did not find a relationship between BMI and frailty among hospitalized older adults. Overweight patients had a survival advantage if they were non-frail or vulnerable. There is need for further longitudinal studies assessing the interaction between frailty and BMI in older adults.

Inappropriate Sinus Tachycardia Following Viral Illness

A 67-year-old female patient with a past medical history of menopause, migraines, and gastro-esophageal disease presented with palpitation, fatigue, and shortness of breath. One month prior to her presentation, she reported having flu-like symptoms. Her EKG showed sinus tachycardia with no other abnormality. Laboratory findings, along with imaging, showed normal results. The event monitor failed to detect any arrythmias. We report a case of inappropriate sinus tachycardia secondary to viral infection as a diagnosis of exclusion.

Readmissions Rates After Myocardial Infarction for Gastrointestinal Bleeding: A National Perspective

BACKGROUND AND AIMS

Gastrointestinal (GI) bleeding is one most common complications of acute myocardial infarction (AMI). We aimed to determine the incidence, in-hospital outcomes, associated healthcare burden and predictors of GI bleeding within 30 days after AMI.

METHODS

Data were extracted from Nationwide Readmission Database 2010-2014. Patients were included if they had a primary diagnosis of ST or non-ST elevation myocardial infarction. Exclusion criteria were admissioned in December, aged less than 18 years and a diagnosis of type-2 MI. The primary outcome was 30-day readmission with upper or lower GI bleeding. Secondary outcomes were in-hospital mortality, etiology of bleeding, in-hospital complications, procedures, length of stay, and total hospitalization charges. Independent predictors of readmission were identified using multivariate logistic regression analysis.

RESULTS

Out of the 3,520,241 patients discharged with ACS, 10,018 (0.3%) were readmitted with GI bleeding within 30 days of discharge. 60% had lower GI bleeding. Most common sources suspected were GI cancers in 17% and hemorrhoidal bleeding in 10%. In hospital mortality rate for readmission was 3.6%. Independent predictors of readmission were age, Charlson comorbidity score, history of chronic kidney disease, GI tumor, inflammatory bowel disease and artificial heart valve. Type of treatment for AMI had no impact on readmission. Patients readmitted had higher rates of shock (adjusted odds ratio, 1.48, 95% CI 1.01-3.72).

CONCLUSIONS

In the first nationwide study, 30-day incidence of GI bleeding after AMI is 0.3%. GI bleeding complicating AMI carries a substantial in-hospital mortality and cost of care.

CK-MB Elevation in Mild Hypothermia: What We Did and We Should Have Done

An 88-year-old male patient with a past medical history of hypertension and gastroesophageal disease presented with nausea, vomiting, and hypothermia. He was admitted for further testing, which revealed elevated creatine kinase and its MB isoenzyme (CK-MB) and troponin with no significant electrocardiogram changes. He denied cardiac symptoms or any previous cardiac history. The patient was treated with fluids and antibiotics in which improvement in his symptoms was noted. In this article, we share this rare case of hypothermia associated with elevation of CK-MB.

Systematic Review of COVID-19 Related Myocarditis: Insights on Management and Outcome

INTRODUCTION

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also referred to as COVID-19, was declared a pandemic by the World Health Organization in March 2020. The manifestations of COVID-19 are widely variable and range from asymptomatic infection to multi-organ failure and death. Like other viral illnesses, acute myocarditis has been reported to be associated with COVID-19 infection. However, guidelines for the diagnosis of COVID-19 myocarditis have not been established.

METHODS

Using a combination of search terms in the PubMed/Medline, Ovid Medline and the Cochrane Library databases and manual searches on Google Scholar and the bibliographies of articles identified, we reviewed all cases reported in the English language citing myocarditis associated with COVID-19 infection.

RESULTS

Fourteen records comprising a total of fourteen cases that report myocarditis/myopericarditis secondary to COVID-19 infection were identified. There was a male predominance (58%), with the median age of the cases described being 50.4 years. The majority of patients did not have a previously identified comorbid condition (50%), but of those with a past medical history, hypertension was most prevalent (33%). Electrocardiogram findings were variable, and troponin was elevated in 91% of cases. Echocardiography was performed in 83% of cases reduced function was identified in 60%. Endotracheal intubation was performed in the majority of cases. Glucocorticoids were most commonly used in treatment of myocarditis (58%). Majority of patients survived to discharge (81%) and 85% of those that received steroids survived to discharge.

CONCLUSION

Guidelines for diagnosis and management of COVID-19 myocarditis have not been established and our knowledge on management is rapidly changing. The use of glucocorticoids and other agents including IL-6 inhibitors, IVIG and colchicine in COVID-19 myocarditis is debatable. In our review, there appears to be favorable outcomes related to myocarditis treated with steroid therapy. However, until larger scale studies are conducted, treatment approaches have to be made on an individualized case-by-case basis.

Coronary subclavian steal syndrome causing myocardial Infarction

Coronary subclavian steal syndrome (CSSS) is a rare complication of the internal mammary artery (IMA) grafting in coronary artery bypass surgery. The technical definition is myocardial ischemia due to the reduced flow of blood, or flow reversal in the IMA graft. This in most cases results from hemodynamically significant proximal subclavian artery stenosis. The clinical presentation is variable and ranges from unstable angina to myocardial infarction, and in some cases, sudden cardiac arrest. CSSS is an entity that is hard to diagnose if one is not actively looking for it. The clinical diagnosis is often complicated, and the prevalence of the disorder is frequently underestimated. In this case presentation, we report a case of myocardial infarction that resulted from significant proximal subclavian artery stenosis.

An Unusual Cause of an Intraperitoneal Bleed: Bleeding Hepatic Artery Pseudoaneurysm Due to an Eroding Cholecystitis

An 80-year-old male patient presented with sepsis secondary to infected central line which was placed for native aortic valve endocarditis. He also had melena and abdominal pain prior to his presentation. Abdominal computed tomography (CT) was done, which showed cholelithiasis. Esophagogastroduodenoscopy was also done with no source of bleeding identified. Later, he developed hemodynamic instability requiring aggressive fluid resuscitation and multiple packed blood cell transfusions. In view of his hemodynamic instability, a repeat abdominal CT scan showed air droplets within the gallbladder pneumobilia, ascites, diverticulosis, and a bleeding infrahepatic hematoma measuring 6 × 10 cm, which was not on his prior scan 2 days prior. A mesenteric arteriogram was performed that identified an aneurysm of the right hepatic artery with no active bleeding; therefore, it was coiled. Due to his continued clinical decompensation, he underwent an urgent open cholecystectomy, in which serosanguineous fluid, cholecystocolic fistula, and old clot related to his previous bleed were encountered. However, control of bleeding was difficult, and the patient expired. We report this case of right hepatic artery aneurysm that we believe its etiology was related to eroding cholecystitis.

COVID-19-Induced Acute Bilateral Optic Neuritis

A 44-year-old male patient with no past medical history presented 2 weeks after seropositive coronavirus disease 2019 (COVID-19) infection with vision problems suggestive of optic neuritis. Radiological testing showed findings suspicious for acute bilateral optic neuritis. The patient had also anti-MOG antibodies. Whether this was an optic neuritis due to COVID-19, MOG antibody disease, or an activation of MOG antibody disease by COVID-19 is discussed in this case.

Hyperbaric oxygen therapy after acute ischemic stroke with large penumbra: a case report

Background

Hyperbaric oxygen therapy (HBOT) for the treatment of acute stroke has been under the radar for a long time. Previous studies have not been able to prove efficacy. Several factors might have contributed to such inconsistent results. The timing of delivering the hyperbaric oxygen in relation to the stage of stroke evolution may be an important factor. This was not taken into account in the previous studies as there was no feasible and standardized method to assess the penumbra in the acute phase. Now with the perfusion scan appearing as a key player in the acute stroke management, precise stroke patient selection for hyperbaric oxygen therapy deserves a second chance similar to mechanical thrombectomy.

Case presentation

A 62-year-old female patient who presented with acute large vessel stroke was not eligible for chemical or mechanical thrombectomy. There was a large penumbra on imaging. She got treated with several sessions of hyperbaric oxygen over a 2-week period immediately after stroke. The patient showed significant improvement on the follow-up perfusion imaging as well as some clinical improvement. The more impressive radiological improvement was probably due to the presence of relatively large core infarction at baseline affecting functional brain areas. The patient continued to improve clinically on her 6-month follow up visit.

Conclusion

Our case demonstrates immediate stroke-related penumbra improvement associated with HBOT. Based on that, we anticipate a potential role for HBOT in acute stroke management considering precise patient selection. Future randomized controlled trials are needed and should take that in consideration.

Concurring hypertrophic cardiomyopathy and takotsubo cardiomyopathy: Assessment and management

The prevalence of takotsubo cardiomyopathy (TCM) has been on the rise, but co-occurrence with hypertrophic cardiomyopathy (HOCM) remains rare. Although presenting patient demographics were similar to those in TCM, the potential for hemodynamic compromise was significantly compounded by the presence of underlying HOCM. Management was similar to standalone TCM, although use of inotropic agents and mechanical support appears to be more prevalent. Despite the increased potential for complications and the paucity of data regarding management, outcomes appear to be mostly favorable in both the hospitalization period and at follow-up. Interestingly, despite a new diagnosis of HOCM in about half the cases described, which signifies no significant left ventricular outflow tract (LVOT) gradient prior to TCM, half of those patients had a persistently elevated LVOT gradient after resolution of TCM. This poses a question of whether or not TCM can predispose to LVOT obstruction in HOCM patients even after its resolution.
