The trial found that abbreviated therapy significantly reduced the risk of bleeding, with no increase in the risk of ischemic events. Landi A et al. Abbreviated or standard antiplatelet therapy in HBR patients: Final 15-month results of the MASTER-DAPT trial. JACC Cardiovasc Interv 2023 Apr 10; 16:798. (https://doi.org/10.1016/j.jcin.2023.01.366)   Study 2: The prevalence and diagnostic significance of de-novo 12-lead ECG changes after COVID-19 infection in elite soccer players is discussed in a recent study by Bhatia RT et al. The study found that over 20% of the players had de-novo ECG changes, which were associated with myocardial inflammation and fibrosis. The authors recommend routine ECG screening for athletes post-COVID-19 infection. Bhatia RT et al. Prevalence and diagnostic significance of de-novo 12-lead ECG changes after COVID-19 infection in elite soccer players. Heart 2023 Mar 27; [e-pub]. (https://doi.org/10.1136/heartjnl-2022-322211)   Study 3: Haupt CE and Marks M discuss the benefits, limits, and risks of AI-generated medical advice in their recent JAMA article. They argue that AI-generated advice has the potential to improve clinical decision-making and reduce errors, but highlight the need for appropriate training, validation, and regulation to ensure patient safety. Haupt CE, Marks M. AI-Generated Medical Advice-GPT and Beyond. JAMA. 2023 Apr 25;329(16):1349-1350. doi: 10.1001/jama.2023.5321. PMID: 36972070.   Study 4: Lee P et al. discuss the benefits, limits, and risks of GPT-4 as an AI chatbot for medicine in their recent NEJM article. They note that while GPT-4 has the potential to improve patient education and communication, it also raises concerns around privacy, liability, and bias. The authors highlight the need for further research and guidelines on the use of AI chatbots in healthcare. Lee P, Bubeck S, Petro J. Benefits, Limits, and Risks of GPT-4 as an AI Chatbot for Medicine. N Engl J Med. 2023 Mar 30;388(13):1233-1239. doi: 10.1056/NEJMsr2214184.
