This week on Medmastery’s Cardiology Digest, we're peeling back the layers of three enlightening studies that are pushing the boundaries of what we know about cardiac care. STUDY #1: First, we revisit the use of an everyday medication to check if it’s doing more harm than good in the elderly. Aspirin, long touted for its preventative benefits, is under scrutiny for its role in anemia. Should we rethink the use of aspirin in primary prevention, especially among the older population? McQuilten, ZK, Thao, LTP, Pasricha, S-R, et al. 2023. Effect of low-dose aspirin versus placebo on incidence of anemia in the elderly: A secondary analysis of the Aspirin in Reducing Events in the Elderly trial. Ann Intern Med. 7: 913–921. (https://www.acpjournals.org/doi/10.7326/M23-0675) STUDY #2: Then, we shift focus to a comparison of approaches to mitral valve repair: the less-invasive minithoracotomy versus the conventional median sternotomy. Patient outcomes and success rates are put under the microscope, so we can tease apart what truly makes a difference in the final result. Is it the size of the incision or the skill of the hands making it?  Akowuah, EF, Maier, RH, Hancock, HC, et al. 2023. Minithoracotomy vs conventional sternotomy for mitral valve repair: A randomized clinical trial. JAMA. 22: 1957–1966. (https://jamanetwork.com/journals/jama/fullarticle/2805908) STUDY #3: Lastly, we wrap up with an insightful discussion on compression stockings after acute DVT, to see if they can prevent post-thrombotic syndrome. Do we have enough evidence to make confident recommendations on the real benefits and drawbacks of compression wearables? And how long should patients use them? We delve into the practical aspects of incorporating the findings of this paper into patient care. Meng, J, Liu, W, Wu, Y, et al. Is it necessary to wear compression stockings and how long should they be worn for preventing post thrombotic syndrome? A meta-analysis of randomized controlled trials. Thromb Res. 225: 79–86.
