Our latest episode dissects three groundbreaking studies that are reshaping our understanding of the heart and its intricate connections to the body and mind.   STUDY #1: First, we explore the potential of high-sensitivity cardiac troponin I (hs-cTnI) in risk-stratifying patients with known coronary artery disease. While current guidelines don't yet recommend these tests, could there be untapped value in using troponin concentration as a preventive treatment guide? Join us as we explore the intriguing possibilities and implications presented in this study from the Journal of the American College of Cardiology. Wereski, R, Adamson, P, Daud, NSS, et al. 2023. High-sensitivity cardiac troponin for risk assessment in patients with chronic coronary artery disease. J Am Coll Cardiol. 6: 473–485. (https://doi.org/10.1016/j.jacc.2023.05.046)   STUDY #2: Next, we shift our focus to the brain-heart connection. Ever wondered about the cognitive repercussions of a myocardial infarction (MI)? This study from JAMA Neurology sheds light on the potential cognitive consequences of an MI.  Johansen, MC, Ye, W, Gross, A, et al. 2023. Association between acute myocardial infarction and cognition. JAMA Neurol. 7: 723–731. (https://doi.org/10.1001/jamaneurol.2023.1331)   STUDY #3: Third, we dive deep (pun intended!) into decompression illness. Certain divers might want to reconsider their next dive because a recent Annals of Internal Medicine study suggests a primary mechanism behind decompression illness that could change the way we perceive diving risks. What are the implications for those passionate about the deep blue? Lee, H-J, Lim, DS, Lee, J, et al. 2023. Decompression illness in divers with or without patent foramen ovale: A cohort study. Ann Intern Med. 7: 934–939. (https://doi.org/10.7326/M23-0260)   Don't miss out on these captivating discussions.
