Item Blood lead level in Chinese adults with and without coronary artery disease(China Science, 2021) Li, Shi-Hong; Zhang, Hong-Ju; Li, Xiao-Dong; Cui, Jian; Cheng, Yu-Tong; Wang, Qian; Wang, Su; Krittanawong, Chayakrit; El-Am, Edward A.; Bou Chaaya, Rody G.; Wu, Xiang-Yu; Gu, Wei; Liu, Hong-Hong; Yan, Xian-Liang; Li, Zhi-Zhong; Yang, Shi-Wei; Sun, Tao; Medicine, School of MedicineBackground: The Trial to Assess Chelation Therapy study found that edetate disodium (disodium ethylenediaminetetraacetic acid) chelation therapy significantly reduced the incidence of cardiac events in stable post-myocardial infarction patients, and a body of epidemiological data has shown that accumulation of biologically active metals, such as lead and cadmium, is an important risk factor for cardiovascular disease. However, limited studies have focused on the relationship between angiographically diagnosed coronary artery disease (CAD) and lead exposure. This study compared blood lead level (BLL) in Chinese patients with and without CAD. Methods: In this prospective, observational study, 450 consecutive patients admitted to Beijing Anzhen Hospital with suspected CAD from November 1, 2018, to January 30, 2019, were enrolled. All patients underwent coronary angiography, and an experienced heart team calculated the SYNTAX scores (SXscore) for all available coronary angiograms. BLLs were determined with atomic absorption spectrophotometry and compared between patients with angiographically diagnosed CAD and those without CAD. Results: In total, 343 (76%) patients had CAD, of whom 42% had low (0-22), 22% had intermediate (23-32), and 36% had high (≥ 33) SXscore. BLLs were 36.8 ± 16.95 μg/L in patients with CAD and 31.2 ± 15.75 μg/L in those without CAD (P = 0.003). When BLLs were categorized into three groups (low, middle, high), CAD prevalence increased with increasing BLLs (P < 0.05). In the multivariate regression model, BLLs were associated with CAD (odds ratio (OR): 1.023, 95% confidence interval (CI): 1.008-1.039; P = 0.0017). OR in the high versus low BLL group was 2.36 (95% CI: 1.29-4.42,P = 0.003). Furthermore, BLLs were independently associated with intermediate and high SXscore (adjusted OR: 1.050, 95% CI: 1.036-1.066; P < 0.0001). Conclusion: BLLs were significantly associated with angiographically diagnosed CAD. Furthermore, BLLs showed excellent predictive value for SXscore, especially for complex coronary artery lesions.Item CAD-LT score effectively predicts risk of significant coronary artery disease in liver transplant candidates(Elsevier, 2021-07) Rachwan, Rayan Jo; Kutkut, Issa; Timsina, Lava R.; Chaaya, Rody G. Bou; El-Am, Edward A.; Sabra, Mohammad; Mshelbwala, Fakilahyel S.; Rahal, Mahmoud A.; Lacerda, Marco A.; Kubal, Chandrashekhar A.; Fridell, Jonathan A.; Ghabril, Marwan S.; Bourdillon, Patrick D.; Mangus, Richard S.; Surgery, School of MedicineBackground & Aims Patients with cirrhosis and significant coronary artery disease (CAD) are at risk of peri-liver transplantation (LT) cardiac events. The coronary artery disease in liver transplantation (CAD-LT) score and algorithm aim to predict the risk of significant CAD in LT candidates and guide pre-LT cardiac evaluation. Methods Patients who underwent pre-LT evaluation at Indiana University (2010-2019) were studied retrospectively. Stress echocardiography (SE) and cardiac catheterization (CATH) reports were reviewed. CATH was performed for predefined CAD risk factors, irrespective of normal SE. Significant CAD was defined as CAD requiring percutaneous or surgical intervention. A multivariate regression model was constructed to assess risk factors. Receiver-operating curve analysis was used to compute a point-based risk score and a stratified testing algorithm. Results A total of 1,771 pre-LT patients underwent cardiac evaluation, including results from 1,634 SE and 1,266 CATH assessments. Risk-adjusted predictors of significant CAD at CATH were older age (adjusted odds ratio 1.05; 95% CI 1.03–1.08), male sex (1.69; 1.16–2.50), diabetes (1.57; 1.12–2.22), hypertension (1.61; 1.14–2.28), tobacco use (pack years) (1.01; 1.00–1.02), family history of CAD (1.63; 1.16–2.28), and personal history of CAD (6.55; 4.33–9.90). The CAD-LT score stratified significant CAD risk as low (≤2%), intermediate (3% to 9%), and high (≥10%). Among patients who underwent CATH, a risk-based testing algorithm (low: no testing; intermediate: non-invasive testing vs. CATH; high: CATH) would have identified 97% of all significant CAD and potentially avoided unnecessary testing (669 SE [57%] and 561 CATH [44%]). Conclusions The CAD-LT score and algorithm (available at www.cad-lt.com) effectively stratify pre-LT risk for significant CAD. This may guide more targeted testing of candidates with fewer tests and faster time to waitlist. Lay summary The coronary artery disease in liver transplantation (CAD-LT) score and algorithm effectively stratify patients based on their risk of significant coronary artery disease. The CAD-LT algorithm can be used to guide a more targeted cardiac evaluation prior to liver transplantation.Item Case Report: A Rare Case of Right-Sided Papillary Fibroelastoma in a 1-Year-Old With Congenital Heart Disease(Frontiers Media, 2021-01-27) Ahmad, Ali; El-Am, Edward A.; Kurmann, Reto D.; Hagler, Donald J.; Bois, Melanie C.; Maleszewski, Joseph J.; Klarich, Kyle W.; Medicine, School of MedicineIntroduction: Cardiac papillary fibroelastomas (PFEs) are the most common primary benign cardiac tumors, although they are somewhat unusual in children and typically seen on the left-sided cardiac valves. Case summary: A 10-week-old patient was found to have a partial atrioventricular canal defect, with associated tricuspid and mitral regurgitation. He was medically managed until 1 year of age, when surgical correction was done. During the procedure, a PFE was found incidentally on the TV. Conclusion: This is one of the youngest patients to be reported with PFE, thus adding to the literature of these unusual cases in children.Item Case Report: A Tale of a Cardiac Mass: Looks Like a Papillary Fibroelastoma, Acts Like a Non-bacterial Thromboendocarditis(Frontiers Media, 2021-11-12) Ahmad, Ali; Arghami, Arman; El-Am, Edward A.; Foley, Thomas A.; Kurmann, Reto D.; Klarich, Kyle W.; Medicine, School of MedicineIntroduction: Benign cardiac tumors and tumor like conditions are a heterogeneous collection of mass lesions that vary widely in their characteristics, such as presentation, size, and location. In some instances, these tumors are found incidentally, and therefore a broad differential diagnosis should be considered. Case: An elderly male with significant unintentional weight loss and a high risk for cancer presented with an incidental valvular cardiac mass. The mass was thought to be a non-bacterial thromboendocarditis on initial clinical evaluation. After multiple imaging modalities, the mass was suspected to be a papillary fibroelastoma (PFE), which was resected due to high stroke risk and multiple previous chronic infarcts on brain MRI. Conclusion: This case highlights the need for a comprehensive cardiac evaluation of a valvular tumor to discern the etiology and rule out other underlying pathophysiological processes that may require alternative interventions to cardiac surgery.Item A Challenging Combination: Anomalous Left Anterior Descending Coronary Artery, Myocardial Bridging, and Endothelial Dysfunction(Frontiers Media, 2020) El-Am, Edward A.; Corban, Michel T.; Pollak, Amy W.; Lerman, Amir; Ammash, Naser M.; Medicine, School of Medicine50 years old female patient with a medical history of hypertension presented to the clinic with chest pain, palpitations, and dyspnea on exertion of 2 years duration. Extensive workup in search of the culprit etiology of her chest pain revealed a challenging combination of an anomalous left anterior descending artery with myocardial bridging and endothelial dysfunction. She was treated medically with long acting nitrates, L-arginine and calcium channel blockers, and remains asymptomatic after 12 months of follow up.Item Increased Risk of Valvular Heart Disease in Systemic Sclerosis: An Underrecognized Cardiac Complication(Journal of Rheumatology, 2021) Kurmann, Reto D.; El-Am, Edward A.; Radwan, Yasser A.; Sandhu, Avneek S.; Crowson, Cynthia S.; Matteson, Eric L.; Warrington, Kenneth J.; Mankad, Rekha; Makol, Ashima; Medicine, School of MedicineObjective: Cardiac involvement is a poor prognostic marker in systemic sclerosis (SSc). While diastolic dysfunction, myocardial fibrosis, and arrhythmias are traditionally considered features of primary cardiac involvement in SSc, the incidence of valvular heart disease (VHD) is not well reported. Our objective was to examine the prevalence of VHD at the time of SSc diagnosis and incidence of VHD during follow-up compared to non-SSc subjects. Methods: Medical records of patients with suspicion of SSc were reviewed to identify incident cases. SSc subjects were matched 1:2 by age and sex to non-SSc subjects. Results: The study included 78 incident SSc cases and 156 non-SSc comparators (56 yrs [± 15.7], 91% female). A nearly 4-fold increase in the prevalence of moderate/severe VHD prior to SSc diagnosis compared to non-SSc subjects (6% vs 0%; P = 0.004) was identified. During follow-up, 18 SSc and 12 non-SSc patients developed moderate/severe VHD. The cumulative incidence of VHD at 10 years after SSc incidence/index was 17.9% (95% CI 10.7-29.9) in patients with SSc compared with 2.3% (95% CI 0.7-7.0) in non-SSc subjects (HR 4.23, 95% CI 2.03-8.83). Coronary artery disease was the only significant risk factor for VHD. Conclusion: Patients with SSc have a 4-fold increase in the prevalence of moderate/severe VHD at diagnosis compared to non-SSc patients. They also have a 4-fold increased risk of developing moderate/severe VHD after diagnosis of SSc. Aortic stenosis and mitral regurgitation have a much higher prevalence in patients with SSc, besides secondary tricuspid regurgitation. Underlying mechanisms for this association require further elucidation.Item Recurrent Parotid Adenocarcinoma Presenting as Diffuse Myocardial Metastatic Disease(Allen Press, 2022) El-Am, Edward A.; Jarori, Upasana; Grethlein, Sara J.; Mastouri, Ronald; Khemka, Abhishek; Medicine, School of MedicineA 64-year-old man who had undergone treatment for left parotid adenocarcinoma presented with progressive exertional shortness of breath. Evaluation revealed metastatic invasion of the myocardium as a rare presentation of recurrent parotid adenocarcinoma. This case highlights the importance of using multimodal imaging methods in diagnostic evaluation and a collaborative multidisciplinary approach in managing patient care.Item Systemic Sclerosis Portends Increased Risk of Conduction and Rhythm Abnormalities at Diagnosis and During Disease Course: A US Population-Based Cohort(Sage, 2021) Radwan, Yasser A.; Kurmann, Reto D.; Sandhu, Avneek S.; El-Am, Edward A.; Crowson, Cynthia S.; Matteson, Eric L.; Osborn, Thomas G.; Warrington, Kenneth J.; Mankad, Rekha; Makol, Ashima; Medicine, School of MedicineObjectives: To study the incidence, risk factors and outcomes of conduction and rhythm disorders in a population-based cohort of patients with systemic sclerosis (SSc) vs. non-SSc comparators. Methods: An incident cohort of patients with SSc (1980-2016) from Olmsted County, MN was compared to age- and sex-matched non-SSc subjects (1:2). Electrocardiograms (ECGs), Holter ECGs, and need for cardiac interventions were reviewed to determine the occurrence of any conduction or rhythm abnormalities. Results: 78 incident SSc cases and 156 comparators were identified (mean age 56 y, 91% female). The prevalence of any conduction disorder prior to SSc diagnosis compared to non-SSc subjects was 15% vs. 7% (p=0.06), and any rhythm disorder was 18% vs. 13% (p=0.33). During a median follow-up of 10.5 years in patients with SSc and 13.0 years in non-SSc comparators, conduction disorders developed in 25 patients with SSc with cumulative incidence of 20.5% (95% CI: 12.4-34.1%) vs. 28 non-SSc patients with cumulative incidence of 10.4% (95% CI: 6.2-17.4%) (HR: 2.57; 95% CI: 1.48-4.45), while rhythm disorders developed in 27 patients with SSc with cumulative incidence of 27.3% (95% CI: 17.9-41.6%) vs. 43 non-SSc patients with cumulative incidence of 18.0% (95% CI: 12.3-26.4%) (HR: 1.62; 95% CI: 1.00-2.64). Age, pulmonary hypertension and smoking were identified as risk factors. Conclusion: Patients with SSc have an increased risk of conduction and rhythm disorders both at disease onset and over time, compared to non-SSc patients. These findings warrant increased vigilance and screening for ECG abnormalities in SSc patients with pulmonary hypertension.
