3. Myocardial Tissue Characterization by CMR Captures Mechanistic Severity Beyond Filling Pressure in HFpEF: The Multicenter DECIPHER HFpEF Study.
PMID:日期:2026-09-16Diastolic dysfunction (DD) in heart failure with preserved ejection fraction (HFpEF) reflects active relaxation (τ) and passive stiffness (β), conflated by end-diastolic pressure (EDP) and potentially requiring different therapies. Whether cardiac magnetic resonance (CMR) tissue mapping captures these beyond filling pressure is unknown. This study aims to determine whether CMR tissue mapping (native T1 corrected for field strength and scanner [T1c], native T2 corrected for field strength and scanner [T2c]) captures τ and β as markers of mechanistic severity in HFpEF beyond EDP. In this prospective multicenter study, patients with suspected HFpEF underwent CMR with sequence-corrected tissue mapping and invasive pressure-volume loop analysis. HFpEF was defined as EDP ≥16 mm Hg (n = 52). Age- and sex-matched control patients (n = 32) and healthy volunteers (n = 18) provided cross-group context. Eighteen catheterized symptomatic patients with normal resting EDP underwent handgrip provocation for a continuum analysis. Partial correlations adjusted T1c-β and T2c-τ associations for EDP. T1c and T2c differed between HFpEF and matched control patients (Cliff's δ 0.74 and 0.80; both P < 0.001). Within HFpEF, T1c correlated with β (partial ρ = 0.47; P = 0.003) and T2c with τ (ρ = 0.35; P = 0.018), both conditional on EDP. Exploratory partitioning around medoids clustering on τ and β identified 2 phenotypes (mild DD [n = 24], severe DD [n = 28]; adjusted Rand index: 0.78) that separated T1c and T2c (both P < 0.001), whereas an EDP median split did not, consistent with tissue mapping reflecting mechanistic severity beyond filling pressure. In invasively characterized HFpEF, CMR tissue mapping captures active relaxation impairment and passive stiffness conditional on filling pressure, robust to clinical covariate adjustment. The exploratory 2-phenotype partition is hypothesis-generating; prospective external validation, including treatment-response data, is required before clinical stratification.

5. Long-Term Warranty Period of Stress CMR and SPECT in Stable Angina: Implications for Repeat Testing.
PMID:日期:2026-09-15Few prospective studies have explored the long-term prognostic value and warranty period of functional imaging in patients with stable chest pain. The CE-MARC (Clinical Evaluation of Magnetic Resonance in Coronary Heart Disease) trial recruited 752 patients with suspected angina and demonstrated the high diagnostic accuracy of stress cardiac magnetic resonance (CMR) compared with single-photon emission computed tomography (SPECT), using invasive coronary angiography as the reference standard. This study aims to assess the comparative long-term prognostic value of stress CMR and SPECT and to establish operational warranty periods for normal test results. Participants in the CE-MARC trial were followed up for major adverse cardiovascular events (MACE), including cardiovascular death, myocardial infarction, and unplanned coronary revascularization. The warranty period identified the time interval during which patients with a normal test result remained 97.5% free of MACE. Multivariable regression analysis identified key warranty period modifiers. Of 752 recruited patients, 652 (86.9%) with CMR and SPECT with follow-up available formed the study cohort. At a median of 15.5 years (Q1-Q3: 12.4-16.6 years), 40 (6.1%) cardiovascular deaths occurred, 29 (4.4%) patients experienced a myocardial infarction, and 47 (7.2%) unplanned revascularization. After adjustment for cardiovascular risk factors, an abnormal CMR remained a strong independent MACE predictor (HR: 2.74; 95% CI: 1.70-4.42; P < 0.001). Patients with a normal test result had a warranty period of 6.8 years for stress CMR and 5.1 years for SPECT. Age, smoking, and diabetes identified higher-risk patients who had a reduced warranty period for a normal result. In a long-term prospective study of patients with stable chest pain, stress CMR remained a strong, independent predictor of hard cardiovascular events, with a warranty period of almost 7 years for a normal scan.

7. The Exciting Future of Cardiovascular Imaging.
PMID:日期:2026-09-11The field of cardiovascular imaging is entering an exciting era of accelerated innovation, fueled by advances in hardware, reconstruction algorithms, and artificial intelligence. Each imaging modality-echocardiography, computed tomography, cardiac magnetic resonance, and nuclear imaging-continues to evolve, with distinct strengths and constraints that complement one another. Collectively, these advances drive improved diagnostic accuracy, refine risk stratification, optimize therapy planning, and enable effective monitoring of treatment response. Artificial intelligence integration will increasingly support the entire imaging workflow, from acquisition planning and reconstruction to segmentation and quality control, facilitating faster, more reproducible, and quantitative imaging, and integrating imaging with multimodal clinical information to enable individualized management. Further, digital twins and physics-based simulation, powered by imaging-derived anatomy and tissue properties, provide mechanistic insight and a platform for scenario testing. This state-of-the-art review outlines key advances across all major modalities and explores how emerging technologies are driving the future of cardiovascular imaging toward data-driven predictive, personalized, and outcome-focused care.

8. Coronary Blood Flow in Women From the CENTURY Trial: Potential Mechanisms for Sex Differences in Coronary Disease.
PMID:日期:2026-09-10Despite comparable cardiovascular risk factors, clinically manifest coronary artery disease (CAD) in women is delayed by up to 2 decades compared with men without a defined physiological basis. This study aims to assess the mechanistic basis of sex differences in CAD using quantitative coronary blood flow (CBF) and coronary flow capacity measured by positron emission tomography in a post hoc analysis of the randomized CENTURY trial. CENTURY trial data were reanalyzed in 331 women vs 697 men for risk factors, age, quantitative CBF, coronary flow capacity, and clinical outcomes through 14 years of follow-up. Women and men had similar age, body mass index, hypertension, diabetes, and cumulative summed risk scores. Still, women had less established CAD, lower coronary artery calcium, and fewer positron emission tomography perfusion defects. Women had approximately half the rates of all-cause death (log-rank P = 0.0223), death or myocardial infarction (log-rank P = 0.0138), revascularization (log-rank P = 0.0004), and major adverse cardiac events (log-rank P < 0.0001) compared with men by Kaplan-Meier plots. Rest and stress CBF were 33% higher in women than in men across all comparable strata of age, body mass index, risk factors, and treatment. When integrated with the published reports showing ∼10% smaller coronary arteries in women, these flow data suggest a potential global endothelial shear stress ∼82% higher in women than in men, suggesting a potential hypothetical chronic, diffuse, antiatherogenic differential mechanism. In the randomized CENTURY trial, women had higher CBF than men across all comparable strata. Combined with the smaller coronary arteries reported in the published reports, this higher CBF suggests a potential, hypothesized higher antiatherogenic ESS that may be a primary, sex-specific physiological mechanism underlying the delayed onset and modifying the course of CAD throughout women's lives.

9. Recommended Criteria to Define Right Ventricular Dysfunction in Severe Secondary Tricuspid Regurgitation: Association With Outcome.
PMID:日期:2026-09-08The TVARC (Tricuspid Valve Academic Research Consortium) and the ASE (American Society of Echocardiography) have proposed echocardiography cutoffs to define right ventricular (RV) dysfunction in secondary tricuspid regurgitation (STR), although these thresholds have not yet been validated. This study aims to evaluate the prognostic value of the proposed thresholds for the main RV function parameters in a large real-world STR cohort. Consecutive patients with ≥ moderate-to-severe STR were included. RV function was assessed by tricuspid annular plane systolic excursion (TAPSE), fractional area change, right ventricular global longitudinal strain, and right ventricular free wall longitudinal strain (RVFWLS). The study outcome was the composite of all-cause mortality and heart failure hospitalization, censored for tricuspid valve intervention. A total of 1,550 patients (mean age: 69 ± 13 years, 50% men) were included. During a median follow-up of 22 months (Q1-Q3: 3-63 months), 703 patients (45%) reached the composite endpoint. All proposed cutoffs were associated with outcomes in univariable Cox analyses, but after multivariable adjustment, mainly strain parameters remained significant. A multiparametric approach combining echocardiographic measures was evaluated, and a stepwise combined grading using TAPSE and RVFWLS showed the strongest association with the composite endpoint; the different grades of RV dysfunction (mild, moderate, and severe, respectively) also remained independently associated (overall value of P < 0.001 and P < 0.005 for TVARC and ASE cutoffs, respectively) with the endpoint. The TVARC and ASE cutoffs for RV dysfunction showed prognostic value in patients with significant STR. Combining TAPSE and RVFWLS may provide a pragmatic, exploratory framework for risk stratification of these patients.
