RESUMO
PURPOSE OF REVIEW: Focused review of select studies presented at the 2022 European Society of Cardiology Congress. RECENT FINDINGS: Included studies assessed the effects of aspirin and omega-3 fatty acid supplements on heart failure (ASCEND study); the impact of icosapent ethyl on ST-elevation MI incidence (REDUCE-IT); air temperature's effect on cardiovascular mortality (EXHAUSTION project); LVEF outcomes after troponin-guided neurohormonal blockade for the prevention of anthracycline toxicity; efficacy of routine stress testing after high-risk PCI (POST-PCI trial); influenza vaccine among patients with acute coronary syndromes (VIP-ACS trial); empagliflozin in patients with acute myocardial infarction (EMMY); effects of comprehensive imaging-based cardiovascular screening on death and cardiovascular events (DANCANVAS); safety of long-term evolocumab in patients with established atherosclerotic cardiovascular disease (FOURIER-OLE); and use of a cardiovascular polypill as a global strategy to improve secondary prevention (SECURE). Research presented at the 2022 ESC Congress highlighted many novel applications of preventative and treatment strategies in cardiology, including the effects of environmental risk factors on the incidence of cardiovascular disease.

In recent years, precision medicine has steadily risen to the forefront of many aspects of medicine, including cardiology [1]. While this field has exponentially expanded and advanced in the last few years, a lot of questions remain regarding exact definition, usage, and clinical applications [2,3]. This review will provide a brief synopsis of the current state of precision medicine, its limitations, future directions, as well as analyze emerging clinical applications in cardiology.

BACKGROUND: Pericoronary adipose tissue (PCAT) attenuation has been identified as a marker for cardiovascular risk. The effect of contrast enhancement on fat attenuation is unknown. We aim to compare precontrast coronary scans to postcontrast CCTA for quantification of pericoronary fat volume and attenuation. METHODS: Thin slice pre- and post-contrast studies obtained at 120â¯kVp, heart rate <60, with no plaque or artifact in the right coronary artery (RCA) were selected. Analysis was limited to pixels -30 Hounsfield units (HU) to -190 HU and from 10â¯mm to 50â¯mm distal to the RCA origin at a radial distance equal to the vessel diameter. A subgroup with no plaque across all coronaries was also analyzed. RESULTS: Of 119 study pairs, the average RCA diameter was highly correlated at 3.85â¯mm (postcontrast) and 3.84â¯mm (precontrast), râ¯=â¯0.97, pâ¯<â¯0.0001. The mean attenuation of pre- and postcontrast images was also highly correlated at -87.02⯱â¯7.15 HU and -82.74⯱â¯6.54 HU, respectively (râ¯=â¯0.65, pâ¯<â¯0.0001). Pericoronary fat volume in the -190 to -30 HU range was 396â¯mm³ lower in the post contrast versus pre-contrast, consistent with higher attenuation (less negative) voxels postcontrast (pâ¯<â¯0.0001). Inter- and intra-reader agreement ranged 95-100% and 90% for precontrast and 85-90% for postcontrast studies, respectively. Subgroup analysis revealed precontrast attenuation -85.59⯱â¯7.53 HU and postcontrast -82.21⯱â¯7.15 HU were highly correlated râ¯=â¯0.67, pâ¯<â¯0.0001. CONCLUSION: Pericoronary fat enhances with iodinated contrast, potentially explaining some of its risk-predictive capabilities. Fat attenuation and volume can be reliably measured from precontrast calcium scans, with volume quantification showing particularly strong correlation. Excellent inter- and intra-reader agreement is also demonstrated.
