Distal Upper Extremity Arterial Calcification as a Predictor for Subclinical Coronary Artery Disease by Coronary Artery Calcium Scoring.

Several studies have linked calcification of the thoracic and lower extremity arterial trunks to an increased risk of developing coronary artery disease (CAD). Calcifications of the radial and/or ulnar artery are regularly identified in hand/wrist x-rays; however, the clinical relevance of these findings as related to identifying subclinical CAD is not well understood. Associations between CAD and upper extremity calcifications have been reported, but the timeline is unclear. The purpose of this study was to evaluate the association between upper extremity arterial calcifications on hand radiographs with CAD by coronary artery calcification (CAC) scoring in patients with no known history of CAD. This is a pilot single-center, prospective, matched cohort study. We included patients with no known history of CAD, related symptoms, or major risk factors. We recruited five patients with calcifications (cal+) and five patients matched by age, race, sex, and medical history but without calcifications (cal-). CAC scores were determined from computed tomography scanning, and lipid profile was evaluated. In the cal+ group, the mean CAC total score was 244.1; in the control (cal-) group, it was 85.2. The mean total cholesterol levels were 220.8 mg per dL and 167 mg per dL in the cal+ and cal- groups, respectively. Two cal+ patients with CAC scores of 937 and 669 died shortly after being enrolled in our study. Preliminary findings suggest that calcifications in the radial or ulnar artery in otherwise asymptomatic patients with no history of CAD may be an independent sign of CAD.

Pulmonary Clostridium perfringens: Seeding Beyond the Gastrointestinal Tract.

Clostridia perfringens infection outside the gastrointestinal system is rare. Here, we report on a 75-year-old man with history of end-stage renal disease presenting after a syncopal event with lactic acidosis, leukocytosis, and mild hyper-bilirubinemia. Chest imaging revealed a loculated, left-sided pleural effusion; diagnostic thoracentesis identified Clostridia perfringens, consistent with an empyema. Video-assisted thoracic left lung decortication was performed; tissue culture also speciated Clostridia perfringens. Further imaging revealed concomitant acute cholecystitis, suggesting hematogenous seeding or transdiaphragmatic extension of Clostridia perfringens to pleural space from an abdominal source. The patient was successfully managed with laparoscopic cholecystectomy and discharged on a one-month course of amoxicillin-sulbactam. This case highlights the potential for Clostridia perfringens to produce a pleuropulmonary infection, necessitating timely diagnosis and intervention, to improve patient outcomes.

The Ultrasound Hepato-Jugular Reflux: Measuring the Hepato-Jugular Reflux with Ultrasound with Comparison to Invasive Right Heart Catheterization.

BACKGROUND: Ultrasound can overcome barriers to visualizing the internal jugular vein, allowing hepato-jugular reflux and jugular venous pressure measurement. We aimed to determine operating characteristics of the ultrasound hepato-jugular reflux and ultrasound jugular venous pressure predicting right atrial and pulmonary capillary occlusion pressures. METHODS: In a prospective observational cohort at three US academic hospitals the hepato-jugular reflux and jugular venous pressure were measured with ultrasound before right heart catheterization. Receiver operating curves, likelihood ratios, and regression models were utilized to compare the ultrasound hepato-jugular reflux and ultrasound jugular venous pressure to the right atrial and pulmonary capillary occlusion pressures. RESULTS: In 99 adults undergoing right heart catheterization, an ultrasound hepato-jugular reflux had a negative likelihood ratio of 0.4 if 0 cm and a positive likelihood ratio of 4.3 if ≥ 1.5 cm for predicting a pulmonary capillary occlusion pressure ≥ 15 mmHg. Regression modeling predicting pulmonary capillary occlusion pressure was not only improved by including the ultrasound hepato-jugular reflux (P < .001), it was the more impactful predictor compared with the ultrasound jugular venous pressure (adjusted odds ratio 2.6 vs 1.2). The ultrasound hepato-jugular reflux showed substantial agreement (kappa 0.76; 95% confidence interval, 0.30-1.21), with poor agreement for the ultrasound jugular venous pressure (kappa 0.11; 95% confidence interval, -0.37-0.58). CONCLUSION: In patients undergoing right heart catheterization, the ultrasound hepato-jugular reflux is reproducible, has modest impact on the probability of a normal pulmonary capillary occlusion pressure when 0 cm, and more substantial impact on the probability of an elevated pulmonary capillary occlusion pressure when ≥ 1.5 cm.

Acute inferior ST-elevation myocardial infarction mimicked by direct lightning strike: a case report.

Background: Direct lightning strikes are rare, and multiple organ systems can be involved. Prognosis is dependent on the severity of the injury. Severe myocardial injury associated with transient electrocardiogram changes, which have been previously described, is a hazardous complication. Case summary: A 35-year-old man with no known past medical history presented unresponsive following a direct lightning strike while sitting in a portable toilet. High-quality cardiopulmonary resuscitation was started in the field, with return of spontaneous circulation (ROSC) after 1 h. Following ROSC, he received volume resuscitation and was maintained on multiple vasopressors. Electrocardiogram showed significant ST-elevations in inferior leads with elevated troponin I, consistent with inferior ST-elevation myocardial infarction. Labs revealed lactic acidosis, hyperkalaemia, acute kidney, and liver injury. Due to concern for plaque rupture, coronary angiography was performed and revealed no obstructive coronary artery disease. Vasopressor support and volume resuscitation were continued for extensive burns covering greater than 30% body surface area. The patient became progressively hypotensive, eventually precipitating pulseless electrical activity arrest. Emergent labs were notable for severe acidaemia. Despite aggressive interventions, he expired due to severe multi-organ failure. Discussion: Direct lightning injuries are rare with serious potential complications. Myocardial damage, either from direct electrical insult or from induced coronary vasospasm, can lead to multi-organ system failure.

Type A Aortic Dissection and Non-Contrast Computed Tomography.

Non-contrast enhanced chest computed tomography (CT) carries a low sensitivity for acute aortic dissection; CT Angiography remains the gold standard. We highlight the potential utility of non-contrast CT for detection of aortic dissection in a case of a young, immunocompromised man presenting with acute abdominal pain and renal injury. Given elevated creatinine, an initial non-contrast chest CT demonstrated subtle findings suggestive of aortic dissection (aneurysmal dilation of the proximal ascending aorta as well as displaced calcified intimal flap/intraluminal high linear density in the thoracic descending and distal abdominal aorta). Subsequent CT angiography confirmed the presence of an extensive type A aortic dissection. He underwent emergent exploratory laparotomy and hemiarch repair. Displaced calcified intimal flaps, intraluminal high-densities, intramural hematoma, and aneurysmal aortic dilation are common non-contrast computed tomography imaging findings that suggest aortic dissection.

Current and emerging pharmacotherapy for the management of hypertrophic cardiomyopathy.

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is one of the most common genetic causes of heart disease. Since the initial description of HCM, there have been minimal strides in management options. Obstructive HCM constitutes a larger subset of patients with increased left ventricular outflow tract gradients causing symptoms. Septal reduction therapy (SRT) has been successful, but it is not the answer for all patients and is not disease modifying. AREAS COVERED: Current guideline recommendations include beta-blockers, calcium channel blockers, or disopyramides for medical management, but there lacks evidence of much benefit with these drugs. In recent years, there has been the emergence of cardiac myosin inhibitors (CMI) which have demonstrated positive results in patients with both obstructive and non-obstructive HCM. In addition to CMIs, other drugs have been investigated as we have learned more about HCM's pathological mechanisms. Drugs targeting sodium channels and myocardial energetics, as well as repurposed drugs that have demonstrated positive remodeling are being investigated as potential therapeutic targets. Gene therapy is being explored with vast potential for the treatment of HCM. EXPERT OPINION: The armamentarium of therapeutic options for HCM is continuously increasing with the emergence of CMIs as mainstays of treatment. The future of HCM treatment is promising.

Reproductive Experiences and Cardiovascular Disease Care in Pregnancy-Capable and Postmenopausal Individuals: Insights From the American Heart Association Research Goes Red Registry.

To evaluate preconception health and adverse pregnancy outcome (APO) awareness in a large population-based registry. We examined data from the Fertility and Pregnancy Survey of the American Heart Association Research Goes Red Registry to questions regarding prenatal health care experiences, postpartum health, and awareness of the association of APOs with cardiovascular disease (CVD) risk. Among postmenopausal individuals, 37% were unaware that APOs were associated with long-term CVD risk, significantly varying by race-ethnicity. Fifty-nine percent of participants were not educated regarding this association by their providers, and 37% reported providers not assessing pregnancy history during current visits, significantly varying by race-ethnicity, income, and access to care. Only 37.1% of respondents were aware that CVD was the leading cause of maternal mortality. There is an urgent, ongoing need for more education on APOs and CVD risk, to improve the health-care experiences and postpartum health outcomes of pregnant individuals.

COVID-19-Associated Coagulopathy: Ascending Aortic Thrombus.

The mechanism of arterial thrombosis in coronavirus disease 2019 (COVID-19) is not completely understood and is attributed to the complex interactions of endothelial injury, platelet hyperactivation, and activated pro-inflammatory cytokines. Management strategies may include a combination of surgery and anticoagulation, or anticoagulation alone. A 56-year-old woman with recent COVID-19 infection presented with chest pain and dyspnea. Chest CT angiography (CTA) and aortic magnetic resonance imaging revealed an intraluminal thrombus in the mid ascending aorta. A multidisciplinary team decided on heparin infusion. She was transitioned to apixaban and a three-month interval outpatient CTA revealed complete resolution of the aortic thrombus.

Landiolol: An Ultra-Short-Acting ß-Blocker.

Landiolol is an ultra-short-acting, highly cardio-selective, ß-blocker, that is currently approved for clinical use in Japan and the European Union, for the treatment of tachyarrhythmias. Landiolol is highly cardio-selective with high ß1 selectivity and receptor affinity, resulting in a more potent chronotropic effect and less potent hypotensive effect compared with other ß-blockers such as esmolol and propranolol. Based on the recent randomized controlled trials, low-dose landiolol may have a beneficial role in the prevention and management of postoperative atrial fibrillation following noncardiac and cardiac surgeries, including on-pump and off-pump coronary artery bypass grafting and valve surgery. Additionally, landiolol may have potential utility for myocardial salvage and prevention of postpercutaneous coronary intervention myocardial infarction. Furthermore, the use of landiolol may also have a therapeutic effect for rate control of sepsis-related tachyarrhythmias. Positive results of recent randomized controlled trials should continue to inspire clinicians to conduct further, larger studies, to find new potential clinical applications for this novel drug.

Recurrent herpes simplex virus encephalitis with presumptive Human Herpesvirus 6 chromosomal integration.

Viral encephalitis can lead to encephalopathy, epileptic activity, focal neurological deficits, and death. Prompt recognition and a high index of clinical suspicion can lead to early initiation of appropriate management. We describe an interesting case of a 61-year-old presenting with fever and altered mental status, diagnosed with numerous episodes of viral encephalitis caused by divergent and recurrent viruses. On his initial presentation, lumbar puncture revealed lymphocytic pleocytosis and positivity for Human Herpesvirus 6 (HHV-6), and he was treated with ganciclovir. On subsequent admissions, he was diagnosed with recurrent HHV-6 encephalitis as well as Herpes Simplex Virus 1 encephalitis and treated with ganciclovir, foscarnet and acyclovir. Despite prolonged courses of treatment and resolution of symptoms, he continued to have persistently high plasma viral loads of HHV-6, consistent with probable chromosomal integration. In this report, we emphasize the clinical pearl of chromosomally integrated HHV-6 that can present in a patient with persistently high plasma viral loads of HHV-6, that are non-responsive to treatment. Individuals with chromosomally integrated HHV-6 may be more susceptible to other viral infections.

Reproductive Experiences and Cardiovascular Disease Care in Pregnancy Capable and Post-Menopausal Individuals: Insights from the American Heart Association Research Goes Red Registry.

Background: Information on reproductive experiences and awareness of adverse pregnancy outcomes (APOs) and cardiovascular disease (CVD) risk among pregnancy-capable and post-menopausal individuals has not been well described. We sought to evaluate preconception health and APO awareness in a large population-based registry. Methods: Data from the Fertility and Pregnancy Survey of the American Heart Association Research Goes Red Registry (AHA-RGR) were used. Responses to questions pertaining to prenatal health care experiences, postpartum health, and awareness of the association of APOs with CVD risk were used. We summarized responses using proportions for the overall sample and by stratifications, and we tested differences using the Chi-squared test. Results: Of 4,651individuals in the AHA-RGR registry, 3,176 were of reproductive age, and 1,475 were postmenopausal. Among postmenopausal individuals, 37% were unaware that APOs were associated with long-term CVD risk. This varied by different racial/ethnic groups (non-Hispanic White: 38%, non-Hispanic Black: 29%, Asian: 18%, Hispanic: 41%, Other: 46%; P = 0.03). Fifty-nine percent of the participants were not educated regarding the association of APOs with long-term CVD risk by their providers. Thirty percent of the participants reported that their providers did not assess pregnancy history during current visits; this varied by race-ethnicity ( P = 0.02), income ( P = 0.01), and access to care ( P = 0.02). Only 37.1% of the respondents were aware that CVD was the leading cause of maternal mortality. Conclusions: Considerable knowledge gaps exist in the association of APOs with CVD risk, with disparities by race/ethnicity, and most patients are not educated on this association by their health care professionals. There is an urgent and ongoing need for more education on APOs and CVD risk, to improve the health-care experiences and postpartum health outcomes of pregnant individuals.

Pancoast Tumor With Cardiac Metastases and Intracardiac Thrombosis.

Pancoast tumor is a rare and aggressive form of lung cancer; cardiac metastasis is very uncommon. We present a case of advanced Pancoast tumor, with extensive cardiac metastases and intracardiac thrombosis in a woman presenting with dyspnea, shoulder pain, and weight loss. A contrast-enhanced chest computed tomographic scan revealed an apical mass, metastatic thoracic nodes, and filling defects within both ventricles. Further imaging with cardiac magnetic resonance imaging revealed 2 left ventricular masses infiltrating into the myocardium suggestive of metastatic disease, and a multilobulated mass within the right ventricle suggestive of intracardiac thrombus. She was initiated on anticoagulation for intracardiac thrombosis. Surgical pathology of biopsied tissue samples was consistent with advanced metastatic lung adenocarcinoma. She was a poor candidate for surgical intervention. Given the patient's goals of care, she was ultimately transitioned to comfort care.

Multi-modality management of hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is an autosomal dominant inherited condition defined by left ventricular wall thickness greater than 15 mm in the absence of other conditions that could explain that degree of hypertrophy. Obstructive HCM associated with left ventricular outflow tract obstruction is defined by an intraventricular systolic pressure gradient greater than or equal to 30 mm Hg. Over the past couple of decades, there has been an expansion of both invasive and pharmacotherapeutic options for patients with HCM, with recent guidelines calling for a melody of invasive and non-invasive treatment strategies. There are several invasive therapies including proven therapies such as alcohol septal ablation and septal myectomy. Novel invasive therapies such as MitraClip, radiofrequency septal ablation and SESAME procedure have more recently been promoted. Pharmacological therapy has also dramatically evolved and includes conventional medications such as beta-blockers, calcium channel blockers, and disopyramide. Mavacamten, a novel cardiac myosin inhibitor, may significantly change management. Other myosin inhibitors and modulators are also being developed and tested in large clinical trials. Given significant phenotypical variability in patients with HCM, clinical management can be challenging, and often requires an individualized approach with a combination of invasive and non-invasive options.

Prevalence and Professional Impact of Mental Health Conditions Among Cardiologists.

BACKGROUND: Mental illness among physicians is an increasingly recognized concern. Global data on mental health conditions (MHCs) among cardiologists are limited. OBJECTIVES: The purpose of this study was to investigate the global prevalence of MHCs among cardiologists and its relationships to professional life. METHODS: The American College of Cardiology conducted an online survey with 5,931 cardiologists globally in 2019. Data on demographics, practice, MHC, and association with professional activities were analyzed. The P values were calculated using the chi-square, Fischer exact, and Mann-Whitney U tests. Univariate and multivariate logistic regression analysis determined the association of characteristics with MHC. RESULTS: Globally, 1 in 4 cardiologists experience any self-reported MHC, including psychological distress, or major or other psychiatric disorder. There is significant geographic variation in MHCs, with highest and lowest prevalences in South America (39.3%) and Asia (20.1%) (P < 0.001). Predictors of MHCs included experiencing emotional harassment (OR: 2.81; 95% CI: 2.46-3.20), discrimination (OR: 1.85; 95% CI: 1.61-2.12), being divorced (OR: 1.85; 95% CI: 1.27-2.36), and age <55 years (OR: 1.43; 95% CI: 1.24-1.66). Women were more likely to consider suicide within the past 12 months (3.8% vs 2.3%), but were also more likely to seek help (42.3% vs 31.1%) as compared with men (all P < 0.001). Nearly one-half of cardiologists reporting MHCs (44%) felt dissatisfied on at least one professional metric including feeling valued, treated fairly, and adequate compensation. CONCLUSIONS: More than 1 in 4 cardiologists experience self-reported MHCs globally, and the association with adverse experiences in professional life is substantial. Dedicated efforts toward prevention and treatment are needed to maximize the contributions of affected cardiologists.

Infective Endocarditis From Pseudomonas aeruginosa and Group C Streptococcus.

Endocarditis is a condition that is usually caused by an infection or inflammation of the endocardium. The disease is commonly seen among intravenous drug abusers, patients with intravenous catheters, and those who undergo cardiovascular and invasive dental procedures. Multiple different pathogens can cause endocarditis (bacterial, fungal, and viral) depending upon the patient's risk factors, epidemiology, and bacteria that are prevalent/endemic to the region. We present the case of a woman who had a history of polysubstance abuse, having presented to the hospital on multiple occasions with bacteremia with a previous admission for endocarditis, who developed a multi-bacterial infection at this presentation involving Pseudomonas aeruginosa and group C Streptococcus, which affected both the right and left side of the heart. In this paper, we reviewed common presentations of endocarditis caused by either bacteria, as well as recommendations for medical or surgical management of the condition.

A Case of SGLT2 Inhibitor-Induced Euglycemic Diabetic Ketoacidosis.

While rare, serious adverse effects including euglycemic diabetic ketoacidosis (EDKA) have been associated with sodium-glucose cotransporter-2 inhibitor (SGLT2i) use. We present an interesting case of SGLT2i-induced EDKA occurring two years after initiation of therapy. Most patients with EDKA recover with prompt recognition and treatment. Patient education about identifying early signs remains a cornerstone of early identification and response to SGLT2i-induced EDKA.

Arterial and Venous Thrombosis From Delayed-Onset Heparin-Induced Thrombocytopenia.

Heparin Induced Thrombocytopenia (HIT) is a life threatening condition which is caused due to antibody formation following exposure to heparin or heparin products. It occurs due to the formation of Platelet Factor 4 antibodies (PF4). HIT is classified into 3 categories based on the duration between heparin exposure and onset of drop in platelet counts. A less common form of HIT is delayed onset HIT which occurs more than 9 days after exposure to heparin or heparin products. In this report we would like to present a rare case of delayed onset HIT which occurred in our patient who presented with rhabdomyolysis and Non ST elevation myocardial infraction (NSTEMI); which resulted in limb ischemia which needed to be treated by amputation of the affected area. We also highlight further management of patients who have thrombotic disease in the setting of HIT and review literature of how heparin or heparin products can be reintroduced in such patient who cannot be managed by other anticoagulation.

A mild, self-resolving case of Epstein-Barr virus-induced hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a multisystem disease caused by an excessive activation of the immune system. In most instances, HLH can be fatal without treatment; a life-threatening syndrome driven by a dysregulated immune system and activation of macrophages resulting in cytokine release and consequent cellular damage. HLH can occur as a consequence of multiple genetic abnormalities or environmental triggers. We present an interesting case of mild, self-resolving, HLH due to Epstein-Barr Virus (EBV) infection in a young woman. The best-known diagnostic criteria are based on the HLH-2004 trial, incorporating either the presence of known mutations or five of eight clinical and laboratory findings. Prompt initiation of etoposide-containing therapy is associated with improved survival. Rituximab, an anti-CD20 antibody, can also remove EBV-harboring B-cells and improve outcomes. In a rare subset of patients, the disease can spontaneously resolve without any therapeutic interventions thus sparing the patients from toxic therapies.
