    (Elsevier, 2024) Joglar, José A.; Chung, Mina K.; Armbruster, Anastasia L.; Benjamin, Emelia J.; Chyou, Janice Y.; Cronin, Edmond M.; Deswal, Anita; Eckhardt, Lee L.; Goldberger, Zachary D.; Gopinathannair, Rakesh; Gorenek, Bulent; Hess, Paul L.; Hlatky, Mark; Hogan, Gail; Ibeh, Chinwe; Indik, Julia H.; Kido, Kazuhiko; Kusumoto, Fred; Link, Mark S.; Linta, Kathleen T.; Marcus, Gregory M.; McCarthy, Patrick M.; Patel, Nimesh; Patton, Kristen K.; Perez, Marco V.; Piccini, Jonathan P.; Russo, Andrea M.; Sanders, Prashanthan; Streur, Megan M.; Thomas, Kevin L.; Times, Sabrina; Tisdale, James E.; Valente, Anne Marie; Van Wagoner, David R.; Pharmacology and Toxicology, School of Medicine
    Aim: The "2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Patients With Atrial Fibrillation" provides recommendations to guide clinicians in the treatment of patients with atrial fibrillation. Methods: A comprehensive literature search was conducted from May 12, 2022, to November 3, 2022, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, the Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. Additional relevant studies, published through November 2022, during the guideline writing process, were also considered by the writing committee and added to the evidence tables, where appropriate. Structure: Atrial fibrillation is the most sustained common arrhythmia, and its incidence and prevalence are increasing in the United States and globally. Recommendations from the "2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation" and the "2019 AHA/ACC/HRS Focused Update of the 2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation" have been updated with new evidence to guide clinicians. In addition, new recommendations addressing atrial fibrillation and thromboembolic risk assessment, anticoagulation, left atrial appendage occlusion, atrial fibrillation catheter or surgical ablation, and risk factor modification and atrial fibrillation prevention have been developed.

    (Springer, 2022) Thakker, Ravi A.; Salazar, Leonardo; Jazar, Deaa Abu; Bhakta, Pooja; Baker, Bryan; Patel, Chandani; Elbadawi, Ayman; Agarwal, Mayank; Albaeni, Aiham; Saleh, Mohammed; Esclovan, Jonathan; El Haddad, Danielle; Alwash, Hashim; Kalra, Ankur; Goel, Sachin S.; Widmer, Robert Jay; Chatila, Khaled; Khalife, Wissam; Motiwala, Afaq; McCracken, Jennifer; Jneid, Hani; Gilani, Syed; Medicine, School of Medicine
    Aspirin is one of the most widely used medications across the global healthcare system and is the foundation in treating ischemic heart disease, as well as secondary prevention for ischemic and valvular heart disease. Challenges arise in treating patients with cardiovascular disease who have concomitant aspirin intolerance. Through an extensive review of the literature, we provide a comprehensive background on the pharmacology of aspirin, the mechanisms behind aspirin intolerance, the importance of aspirin in cardiovascular disease, and the management of aspirin intolerance in both acute coronary syndrome and stable coronary artery disease. Our review includes a multidisciplinary approach from the internist, allergist/immunologist, and cardiologist when evaluating this important patient population.

    Facilitating Exercise Habit Formation among Cardiac Rehabilitation Patients: A Randomized Controlled Pilot Trial
    (MDPI, 2021-06-14) Kaushal, Navin; Payer, Marie; Bérubé, Béatrice; Juneau, Martin; Bherer, Louis; Health Sciences, School of Health and Human Sciences
    Background: The importance of promoting exercise adherence among individuals with acute coronary syndrome (ACS) is imperative. However, challenges in maintaining behavior among ACS patients are also well-documented. Emerging findings in the general population have supported the use of habit-formation techniques, which include incorporating routine consistency and cues, to be effective for facilitating exercise behavior. The effectiveness of habit formation approaches, however, has not been tested on participants with ACS. The purpose of this study was to test the effectiveness of facilitating physical activity habits among patients with ACS in a two-arm, parallel design, randomized controlled pilot trial. Methods: Participants (n = 13) were older adult patients (M age = 64.20, SD = 5.35) with ACS who were referred to a cardiac rehabilitation center. The experimental group attended monthly group meetings from months 1-3 and received phone call follow-ups from months 4-6. Conclusions: The experimental group showed an increase in weekly moderate-to-vigorous level physical activity, M = 228.20 mins (SD = 112.45), compared with the control group, M = 151.17 (SD = 112.22), d = 0.61. The experimental condition also showed greater use of routine consistency (experimental: M = 4.60 (SD = 0.548); control: M = 3.76 (SD = 1.62)) and cue usage (experimental: M = 3.60 (SD = 0.471); control: M= 2.60 (SD = 0.398)) over the control condition at the six-month mark. The study supports the effectiveness of habit-building techniques among patients with ACS, with effect sizes ranging from a medium to large magnitude. Findings from this pilot study support a full clinical trial with larger sample size.

    Guidelines for reasonable and appropriate care in the emergency department (GRACE): Recurrent, low-risk chest pain in the emergency department
    (Wiley, 2021) Musey, Paul I., Jr.; Bellolio, Fernanda; Upadhye, Suneel; Chang, Anna Marie; Diercks, Deborah B.; Gottlieb, Michael; Hess, Erik P.; Kontos, Michael C.; Mumma, Bryn E.; Probst, Marc A.; Stahl, John H.; Stopyra, Jason P.; Kline, Jeffrey A.; Carpenter, Christopher R.; Emergency Medicine, School of Medicine
    This first Guideline for Reasonable and Appropriate Care in the Emergency Department (GRACE-1) from the Society for Academic Emergency Medicine is on the topic: Recurrent, Low-risk Chest Pain in the Emergency Department. The multidisciplinary guideline panel used The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding eight priority questions for adult patients with recurrent, low-risk chest pain and have derived the following evidence based recommendations: (1) for those >3 h chest pain duration we suggest a single, high-sensitivity troponin below a validated threshold to reasonably exclude acute coronary syndrome (ACS) within 30 days; (2) for those with a normal stress test within the previous 12 months, we do not recommend repeat routine stress testing as a means to decrease rates of major adverse cardiac events at 30 days; (3) insufficient evidence to recommend hospitalization (either standard inpatient admission or observation stay) versus discharge as a strategy to mitigate major adverse cardiac events within 30 days; (4) for those with non-obstructive (<50% stenosis) coronary artery disease (CAD) on prior angiography within 5 years, we suggest referral for expedited outpatient testing as warranted rather than admission for inpatient evaluation; (5) for those with no occlusive CAD (0% stenosis) on prior angiography within 5 years, we recommend referral for expedited outpatient testing as warranted rather than admission for inpatient evaluation; (6) for those with a prior coronary computed tomographic angiography within the past 2 years with no coronary stenosis, we suggest no further diagnostic testing other than a single, normal high-sensitivity troponin below a validated threshold to exclude ACS within that 2 year time frame; (7) we suggest the use of depression and anxiety screening tools as these might have an effect on healthcare use and return emergency department (ED) visits; and (8) we suggest referral for anxiety or depression management, as this might have an impact on healthcare use and return ED visits.

    Isolated Right Ventricular Myocardial Infarction Presenting With Anterior ST-Segment Elevation
    (Elsevier, 2022-05-04) Mallory, Ryan; Kreutz, Rolf P.; Medicine, School of Medicine
    Isolated right ventricular myocardial infarctions (MIs) are rare, especially those presenting with anterior ST-segment elevation, which is normally seen in anterior MI. This occurs if the right coronary artery is nondominant. Differentiating between them is important for clinical management. Our case demonstrates a right ventricular MI presenting as an anterior ST-segment elevation myocardial infarction.

    TACE/ADAM17 substrates associate with ACS (Ep-CAM, HB-EGF) and follow-up MACE (TNFR1 and TNFR2)
    (Elsevier, 2022-09-28) Chemaly, Melody; McAllister, Roisin; Peace, Aaron; Bjourson, Anthony John; Watterson, Steve; Parton, Andrew; Clauss, Matthias; McGilligan, Victoria; Cellular and Integrative Physiology, School of Medicine
    Background and aims: TACE/ADAM17 is a membrane bound metalloprotease, which cleaves substrates involved in immune and inflammatory responses and plays a role in coronary artery disease (CAD). We measured TACE and its substrates in CAD patients to identify potential biomarkers within this molecular pathway with potential for acute coronary syndrome (ACS) and major adverse cardiovascular events (MACE) prediction. Methods: Blood samples were obtained from consecutive patients (n = 229) with coronary angiographic evidence of CAD admitted with ACS or electively. MACE were recorded after a median 3-year follow-up. Controls (n = 115) had a <10% CAD risk as per the HeartSCORE. TACE and TIMP3 protein and mRNA levels were measured by ELISA and RT-qPCR respectively. TACE substrates were measured using a multiplex proximity extension assay. Results: TACE mRNA and cell protein levels (p < 0.01) and TACE substrates LDLR (p = 0.006), TRANCE (p = 0.045), LAG-3 (p < 0.001) and ACE2 (p < 0.001) plasma levels were significantly higher in CAD patients versus controls. TACE inhibitor TIMP3 mRNA levels were significantly lower in CAD patients and tended to be lower in the ACS population (p < 0.05). TACE substrates TNFR1 (OR:3.237,CI:1.514-6.923,p = 0.002), HB-EGF (OR:0.484,CI:0.288-0.813,p = 0.006) and Ep-CAM (OR:0.555,CI:0.327-0.829,p = 0.004) accurately classified ACS patients with HB-EGF and Ep-CAM levels being lower compared to electively admitted patients. TNFR1 (OR:2.317,CI:1.377-3.898,p = 0.002) and TNFR2 (OR:1.902,CI:1.072-3.373,p = 0.028) were significantly higher on admission in those patients who developed MACE within 3 years. Conclusions: We demonstrate a possible role of TACE substrates LAG-3, HB-EGF and Ep-CAM in atherosclerotic plaque development and stability. We also underline the importance of measuring TNFR1 and TNFR2 earlier than previously appreciated for MACE prediction. We report an important role of TIMP3 in regulating TACE levels.
