Today we dive into three cardiology papers with important insights for cardiac care. STUDY #1: We explore an analysis that compares Coronary CT Angiography (CCTA) with stress modalities like SPECT-MPI. We see if CCTA has the potential to reduce the need for invasive angiography, and how it stacks up against other testing strategies. Zito, A, Galli, M, Biondi-Zoccai, G, et al. 2023. Diagnostic strategies for the assessment of suspected stable coronary artery disease: A systematic review and meta-analysis. Ann Intern Med. 6: 817–826. (https://www.acpjournals.org/doi/10.7326/M23-0231) STUDY #2: We discuss the approval of a dual-chamber leadless pacemaker system by the FDA. Although this study supports the efficacy of this innovative approach in certain scenarios, it also raises important concerns.  Knops, RE, Reddy, VY, Ip, JE, et al. 2023. A dual-chamber leadless pacemaker. N Engl J Med. 25: 2360–2370. (https://www.nejm.org/doi/10.1056/NEJMoa2300080) STUDY #3: We look at a comprehensive retrospective study that evaluates aggressive management of hypertension in hospitalized adults. What are the ramifications of minimizing the use of BP-lowering agents, particularly intravenous ones, in certain inpatient scenarios? Anderson, TS, Herzig, SJ, Jing, B, et al. 2023. Clinical outcomes of intensive inpatient blood pressure management in hospitalized older adults. JAMA Intern Med. 7: 715–723.
