Cardiology: What You May Have Missed in 2023.

Cardiology and all its subspecialties continue to push the envelope in developing new treatment strategies for a wide variety of diseases. After screening more than 1300 articles, we highlight a selection of important cardiology articles published in 2023. Starting with prevention, we note articles that look at the effect of semaglutide in patients with obesity as well as a first-in-class drug, bempedoic acid, on cardiovascular outcomes. We have also examined new evidence comparing conservative management with invasive management of frail, older patients with non-ST-segment elevation myocardial infarction (NSTEMI). In patients with cardiac arrest secondary to NSTEMI, another article examines the rationale for expedited transfer to a cardiac arrest center. The STREAM-2 (Strategic Reperfusion in Elderly Patients Early After Myocardial Infarction) trial builds on looking at half-dose thrombolysis in older populations with STEMI. Emphasis is placed on guideline-directed medical therapy before hospital discharge in those with heart failure. In addition, in patients with stable symptomatic coronary artery disease, initial noninvasive testing using coronary computed tomography angiography may be a viable option compared with invasive strategies. More details have emerged on anticoagulation strategies in those with device-detected atrial fibrillation. Finally, transcatheter approaches to treat both mitral and tricuspid regurgitation have also been included.
