In coronary computed tomography angiography (CTA), these features may mitigate calcium blooming, enhance stenosis quantification, limit stenosis overestimation, and reduce low-yield referrals to invasive coronary angiography (ICA).OBJECTIVESThis meta-analysis compared diagnostic outcomes between PCD-CT and EID-CT in adults with stable coronary artery disease undergoing coronary CTA.METHODSThe authors' protocol was preregistered and followed the PRISMA 2020 guidelines. Primary outcomes were vessel-level stenosis reclassification, downstream ICA referral, and revascularization rates among those referred. Where multiple studies with compatible definitions were available, random-effects meta-analysis was performed; otherwise, results were described narratively.RESULTSFifteen studies (N = 11,350) met inclusion criteria. At the vessel level, PCD-CT down-classified stenosis severity in a pooled absolute proportion of 34.2% of vessels compared with EID-CT (95% CI: 27.3-41.9; P < 0.0001). This was associated with fewer downstream ICA referrals (pooled OR: 0.71; 95% CI; 0.63-0.79; P < 0.0001) and higher rates of revascularization among those undergoing ICA (OR: 1.43; 95% CI: 1.14-1.79; P = 0.0017). Stratified by coronary artery calcium score (CACS), ICA referrals were lower with PCD-CT when CACS was <400 (OR: 0.62; 95% CI: 0.52-0.75; P < 0.0001) and trended lower when CACS ≥400 (OR: 0.42; 95% CI: 0.16-1.11; P = 0.08).CONCLUSIONSCompared against conventional EID-CT, PCD-CT was associated with down-classification of stenosis severity, translating to fewer referrals for ICA and a greater rate of revascularization when angiography is undertaken.","PeriodicalId":14767,"journal":{"name":"JACC.

Noninvasive diagnosis remains challenging, because resting diastolic pressures may be normal, and even when abnormal, currently applied noninvasive indices lack sensitivity. The pathophysiology of HFpEF extends far beyond diastolic dysfunction, and such complexity can be better understood through imaging. This State-of-the-Art Review emphasizes echocardiography and other noninvasive imaging approaches as the first-line tools for HFpEF evaluation, while linking multimodality imaging to invasive hemodynamics as a physiologic reference standard. The authors emphasize evidence-based, multiparametric assessment, where combined cardiopulmonary exercise testing with exercise stress echocardiography can quantify the diverse reserve limitations that characterize HFpEF, including cardiac and extracardiac contributors, atrial and right heart dysfunction, pulmonary vascular and ventilatory limitation, dynamic atrioventricular regurgitation, extrinsic restraint, pulmonary congestion, and peripheral impairments, acknowledging that such phenotyping must be anchored to actionable findings and evidence-based interventions. The authors describe the potential role of exercise cardiac magnetic resonance and artificial intelligence-enabled imaging analysis for phenotyping and risk stratification. Finally, the authors propose an echo-first Bayesian pathway that updates pretest to posttest probability and supports identification of patients in whom invasive hemodynamic exercise testing may be required to confirm the diagnosis and validate imaging markers against invasively measured congestion.","PeriodicalId":14767,"journal":{"name":"JACC.

Two prevailing hypotheses posit spotty calcification as either a passive indicator of unstable plaque or an active catalyst of plaque vulnerability. Alongside this conceptual development, there has been paired evolution in radiologic characterization, with various imaging modalities demonstrating commendable accuracy in identifying spotty calcification. Many studies have linked the presence of spotty calcification to plaque instability and have reported a higher frequency in culprit lesions leading to acute coronary syndrome. Researchers have thus explored medications such as statins, metformin, and omega-3 fatty acids for their impact on the development and progression of spotty calcification. However, the field lacks standardized definitions that will enhance the clinical utility of this finding. This paper summarizes the evidence that describes spotty calcification as a unique plaque phenotype, its radiologic characteristics on routine cardiac imaging modalities, and its clinical relevance as a novel radiomarker of vulnerable coronary artery disease. This paper benefits from a systematic review of the evidence and, where possible, meta-analysis of the available data to address key questions conclusively in each of 3 areas of interest.</div></div>","PeriodicalId":14767,"journal":{"name":"JACC.
