BACKGROUND
Current guidelines recommend to perform noninvasive functional imaging in patients with obstructive coronary artery disease (CAD) on coronary computed tomography angiography (CCTA). However, the prognostic value of stress cardiovascular magnetic resonance (CMR) over traditional risk factors and CCTA is not known.
PURPOSE
To assess the incremental prognostic value of stress CMR beyond traditional risk factors and CCTA in patients with obstructive CAD on CCTA.
METHODS
Between 2008 and 2020, consecutive symptomatic patients without known CAD referred for CCTA were screened. Among those, patients with obstructive CAD (at least 1 ≥50% stenosis on CCTA) and referred for functional stress CMR were included and followed for the occurrence of major adverse cardiovascular events (MACE), defined by cardiovascular death or nonfatal myocardial infarction. Univariable and multivariable Cox regressions were performed to determine the prognostic value of CCTA and CMR findings.
RESULTS
Of 2,210 patients who completed the CMR protocol, 2,038 patients (46.5% male, mean age 69.8 ± 12.2 years) completed the follow-up (median 6.8 [IQR 5.9-9.2] years); 281 experienced a MACE (13.8%). Stress CMR was well tolerated without severe adverse events. Using Kaplan-Meier analysis, inducible ischemia and late gadolinium enhancement (LGE) were significantly associated with the occurrence of MACE (hazard ratio, HR: 4.51, [95%CI: 3.55-5.74]; and HR: 3.32, [95%CI: 2.55-4.32], respectively; both p < 0.001). In multivariable Cox regression, the presence of inducible ischemia and LGE were independent predictors of a higher incidence of MACE (HR: 3.97, [95%CI: 3.43-5.13]; HR: 2.30, [95%CI: 1.52-3.33]; respectively, both p < 0.001). After adjustment, stress CMR findings showed the best improvement in model discrimination and reclassification above traditional risk factors and CCTA findings (C statistic improvement: 0.08; NRI = 0.421; IDI = 0.047).
CONCLUSIONS
In symptomatic patients with obstructive CAD of unknown significance on CCTA, stress CMR has an incremental prognostic value to predict MACE over traditional risk factors and CCTA findings. Abstract Figure. Kaplan-Meier curves for MACE Abstract Figure. Competitive risk analysis

Abstract
Heart failure (HF) has high event rates, mortality, and is challenging to manage in clinical practice. Clinical management is complicated by complex therapeutic strategies in a population with a high prevalence of comorbidity and general frailty. In the last four years, an abundance of research has become available to support multidisciplinary management of heart failure from within the hospital through to discharge and primary care as well as supporting diagnosis and comorbidity management. Within the hospital setting, recent evidence supports sacubitril-valsartan combination in frail, deteriorating or de novo patients with LVEF≤40%. Furthermore, new strategies such as SGLT2 inhibitors and vericiguat provide further benefit for patients with decompensating HF. Studies with tafamidis report major clinical benefits specifically for patients with ATTR cardiac amyloidosis, a remaining underdiagnosed and undertreated disease. New evidence for medical interventions supports his bundle pacing to reduce QRS width and improve haemodynamics as well as ICD defibrillation for non-ischemic cardiomyopathy. The Mitraclip reduces hospitalisations and mortality in patients with symptomatic, secondary mitral regurgitation and ablation reduces mortality and hospitalisations in patients with paroxysmal and persistent atrial fibrillation. In end-stage HF, the 2018 French Heart Allocation policy should improve access to heart transplants for stable, ambulatory patients and, mechanical circulatory support should be considered to avoid deteriorating on the waiting list. In the community, new evidence supports that improving discharge education, treatment and patient support improves outcomes. The authors believe that this review fills the gap between the guidelines and clinical practice and provides practical recommendations to improve HF management.

BACKGROUND
While current guidelines recommend to perform a noninvasive test to detect coronary artery disease, stress tests are deemed inconclusive in almost a third of cases. The strategy for risk stratification after inconclusive stress testing is not well standardized.
PURPOSE
To assess the prognostic value of stress cardiovascular magnetic resonance (CMR) parameters and CMR-based coronary revascularization in patients after inconclusive stress testing.
METHODS
Between 2008 and 2020, consecutive patients with a first inconclusive stress test referred for vasodilator stress perfusion CMR were followed for the occurrence of major adverse cardiovascular events (MACE), defined by cardiovascular death or nonfatal myocardial infarction. CMR-related coronary revascularization was defined as any revascularisation occurring within 90 days after CMR. Univariable and multivariable Cox regressions were performed to determine the prognostic value of each parameter.
RESULTS
Of 1,563 patients who completed the CMR protocol, 1,402 patients (66.7% male, mean age 69.5 ± 11.0 years) completed the follow-up (median[interquartile range], 6.5 [5.6-7.5] years); 197 experienced a MACE (14.1%). Stress CMR was well tolerated without severe adverse events. Using Kaplan-Meier analysis, inducible ischemia and late gadolinium enhancement (LGE) were significantly associated with the occurrence of MACE (hazard ratio, HR: 2.88 [95%CI, 2.18-3.81]; and HR: 1.46 [95%CI, 1.16-1.89], both p < 0.001; respectively). In multivariable Cox regression, the presence and extent of inducible ischemia were independent predictors of a higher incidence of MACE (HR: 2.53 [95%CI, 1.89-3.40]; and HR: 1.58 [95%CI, 1.47-1.71]; both p < 0.001; respectively). After adjustment, the extent of inducible ischemia showed the best improvement in model discrimination above traditional risk factors (C-statistic 0.75 [95%CI: 0.69-0.81] with C-statistic improvement: 0.12). The study showed no benefit of CMR-related coronary revascularization in reducing MACE.
CONCLUSION
In patients with a first inconclusive stress test, stress CMR has good prognostic value to predict MACE offering an incremental prognostic value over traditional risk factors.

BACKGROUND
Left atrial (LA) and left ventricular (LV) structural and functional parameters have independent prognostic values as predictors of atrial fibrillation (AF).
PURPOSE
Due to the intrinsic physiological relationship between LA and LV, we sought to investigate the prognostic value of a left atrioventricular coupling index (LACI) as well as change in LACI to predict incident AF in a multi-ethnic population.
METHODS
In the Multi-Ethnic Study of Atherosclerosis (MESA), 1,911 study participants, free of clinically recognized AF and cardiovascular disease at baseline, had LACI assessed with CMR imaging at baseline (Exam 1, 2000–2002), and ten years later (Exam 5, 2010–2012). LACI was defined as the ratio of LA to LV end-diastolic volumes. Univariable and multivariable Cox proportional hazard models were used to evaluate the associations of LACI and average annualized change in LACI (ΔLACI) with incident AF.
RESULTS
Among the 1,911 participants (mean age 59 ± 9 years and 47.5% male participants), 87 incident AF events occurred over 3.9 ±0.9 years following the second imaging (Exam 5). After adjustment for traditional risk factors, greater LACI and ΔLACI were independently associated with AF (HR 1.69, 95% CI [1.46-1.96] and HR 1.71, 95% CI [1.50-1.94], respectively; both p < 0.0001). Adjusted models for LACI and ΔLACI showed significant improvement in model discrimination compared to currently used AF risk score model for predicting AF incidence (C-statistic: 0.78 vs. 0.74, and C-statistic: 0.80 vs. 0.74, respectively). The LACI and ΔLACI also showed superior discrimination performance for AF compared to the multivariable model including CHARGE-AF score, and individual LA or LV parameters.
CONCLUSIONS
Atrioventricular coupling (LACI) and coupling change (ΔLACI) are strong predictors for AF incidence in a multi-ethnic population. Both have incremental prognostic value for predicting AF over traditional risk factors, and superior discrimination power compared to the CHARGE-AF score and to individual LA or LV parameters.

BACKGROUND
While the benefit of coronary revascularization in patients with stable coronary artery disease (CAD) is debated, data assessing the potential interest of stress CMR to guide coronary revascularization are limited.
PURPOSE
To assess the long-term prognostic value of stress CMR-related coronary revascularization in consecutive patients from a large registry.
METHODS
Between 2008 and 2018, a retrospective cohort study with a median follow-up of 6.0 years (interquartile range: 5.0-8.0) included all consecutive patients referred for stress CMR. Stress CMR-related coronary revascularization was defined by any coronary revascularization performed within 90 days after CMR. The primary outcome was all-cause death based on the electronic National Death Registry.
RESULTS
Among the 31,752 consecutive patients (mean age 63.7 ± 12.1 years and 65.7% males), 2,679 (8.4%) died at 206,453 patient-years of follow-up. Inducible ischemia and late gadolinium enhancement (LGE) by CMR were associated with death (both p < 0.001). In multivariable Cox regression, inducible ischemia and LGE were independent predictors of death (HR = 1.61; 99.5%CI 1.41-1.84; HR = 1.62; 99.5%CI 1.41-1.86, respectively; p < 0.001). CMR-related coronary revascularization was an independent predictor of greater survival (HR: 0.66; 99.5%CI: 0.52-0.84; p < 0.001). CMR-related revascularization was associated with a lower incidence of death in patients with severe inducible ischemia (p < 0.001), but showed no benefit in patients with mild or moderate ischemia (p = 0.109).
CONCLUSIONS
In this large observational series of consecutive patients, stress perfusion CMR had important incremental long-term prognostic value to predict death over traditional risk factors. CMR-related revascularization was associated with a lower incidence of death in patients with severe ischemia.

Abstract
Funding Acknowledgements Type of funding sources: None. BACKGROUND Inducible ischemia is a strong marker of vascular vulnerability that may be a key pathogenetic determinant of COVID-19 severity. PURPOSE This study investigated the prognostic value of prior inducible ischemia on stress perfusion CMR to predict death in patients hospitalized for COVID-19. METHODS In an observational study, we retrospectively analyzed consecutive patients referred for stress perfusion CMR within last two years prior to hospitalization for COVID-19. The primary outcome was all-cause death, including in-hospital and post-hospitalisation deaths, based on the electronic national death registry. RESULTS Among the patients referred for stress perfusion CMR, 481 were hospitalized for COVID-19 (mean age =68.4 ± 9.6 years, 61.3% males) and completed the follow-up (median 73[36-101] days). There were 93 (19.3%) all-cause deaths, of which 13.7% were in-hospital and 5.6% post-hospitalisation deaths. Using Kaplan-Meier analysis, age, male gender, hypertension, diabetes, known CAD, the presence of prior inducible ischemia, the number of ischemic segments, the presence of LGE, and LVEF were significantly associated with all-cause death. In multivariable stepwise Cox regression analysis, age (HR: 1.04; 95%CI:1.01-1.07, p = 0.023), hypertension (HR: 2.77; 95%CI:1.71-4.51, p < 0.001), diabetes (HR: 1.72; 95%CI:1.08-2.74, p = 0.022), known CAD (HR: 1.78; 95%CI:1.07-2.94, p = 0.025) and the presence of prior inducible ischaemia (HR: 2.05; 95%CI:1.27-3.33, p = 0.004) were independent predictors of all-cause death. CONCLUSIONS In COVID-19 patients, prior inducible myocardial ischemia by stress CMR over the last two years preceding the COVID-19 pandemic was independently associated with all-cause in-hospital and post-hospitalisation deaths, suggesting involvement of vasculature and endothelial dysfunction in the severity of COVID-19.

BACKGROUND
Several studies have shown the excellent prognostic value of stress cardiovascular magnetic resonance (CMR). However, its prognostic value in patients with pacemaker (PM) remains unknown because most studies excluded PM patients.
PURPOSE
This study aimed to assess the prognostic value of vasodilator stress perfusion CMR in patients with PM.
METHODS
Consecutive patients with MR-conditional pacemakers referred for stress perfusion CMR at 1.5 T were followed for the occurrence of major adverse cardiovascular events (MACE), defined by cardiovascular death or nonfatal myocardial infarction. Cox regressions analyses were performed to determine the prognostic value of CMR-parameters. The quality of CMR was rated by two observers blinded to clinical details. Data on pacemaker and leads were collected pre- and post-CMR.
RESULTS
Of 224 patients who completed the stress CMR protocol, 2 patients had inconclusive stress CMR due to artefact and 203 patients (72.9% male, mean age 71.4 ± 8.7 years) completed the follow-up (median [interquartile range], 7.0 [5.2-7.3] years). Among those, 23 experienced a MACE (11.3%). Stress CMR was well tolerated with no major adverse events. All scans were completed successfully with no significant change in lead thresholds or pacing parameters. Overall, the image quality was rated good or excellent in 84.1% of segments. Using Kaplan-Meier analysis, inducible ischemia and late gadolinium enhancement (LGE) were significantly associated with the occurrence of MACE (hazard ratio, HR: 11.80 [95% CI, 4.63-30.30]; and HR: 6.74 [95% CI, 2.47-18.40], both p < 0.001; respectively). In multivariable Cox regression, inducible ischemia and LGE were independent predictors of a higher incidence of MACE (HR: 5.24 [95% CI, 2.61-14.40]; and HR: 2.98 [95% CI, 2.25-4.02]; both p < 0.001; respectively). In patients with ischemia, CMR-related coronary revascularization showed no benefit in reducing MACE (p = 0.25).
CONCLUSION
Stress CMR is safe, feasible and has a good discriminative prognostic value in consecutive patients with PM.

BACKGROUND
Recurrence of cardiovascular (CV) events remains a substantial cause of mortality and morbidity among patients with previous coronary revascularization.
PURPOSE
The aim was to assess the prognostic value of stress cardiovascular magnetic resonance (CMR) parameters and CMR-based revascularization in patients with history of percutaneous coronary intervention (PCI).
METHODS
Between 2011 and 2014, consecutive patients with history of PCI referred for stress perfusion CMR were followed for the occurrence of major adverse cardiovascular events (MACE), defined by cardiovascular death or nonfatal myocardial infarction. Patients with prior coronary artery bypass graft were excluded. CMR-related coronary revascularization was defined as any revascularization occurring within 90 days after CMR. Univariable and multivariable Cox regressions were performed to determine the prognostic value of each parameter.
RESULTS
Of 1,762 patients who completed the CMR protocol, 1,624 patients (81.7% male, mean age 67.9 ± 10.4 years) completed the follow-up (median [interquartile range], 6.7 [5.6–7.3] years); 251 experienced a MACE (15.5%). Stress CMR was well tolerated. Using Kaplan-Meier analysis, inducible ischemia and late gadolinium enhancement (LGE) were significantly associated with the occurrence of MACE (hazard ratio, HR: 2.70 [95%CI, 2.11–3.46], p < 0.001; and HR: 1.52 [95%CI, 1.16–1.99], p = 0.002; respectively). In multivariable Cox regression, inducible ischemia and LGE were independent predictors of a higher incidence of MACE (HR: 2.83 [95%CI, 2.20–3.64]; p < 0.001; and HR: 1.42 [95%CI, 1.06–1.91]; p = 0.012; respectively). CMR-related coronary revascularization was associated with a lower incidence of MACE, even after adjustment.
CONCLUSIONS
Stress CMR and CMR-related revascularization were independently associated with MACE in patients with history of PCI.

BACKGROUND
Although left atrial (LA) and left ventricular (LV) structural and functional parameters have independent prognostic value as predictors of HF, the close physiological relationship between LA and LV suggest that the assessment of LA/LV coupling could better reflect left atrioventricular dysfunction and be a better predictor of heart failure (HF).
PURPOSE
We investigated the prognostic value of a left atrioventricular coupling index (LACI), measured by cardiovascular magnetic resonance (CMR), as well as change in LACI to predict incident HF in the Multi-Ethnic Study of Atherosclerosis (MESA).
METHODS
In the MESA, 2,250 study participants, free of clinically recognized HF and cardiovascular disease at baseline, had LACI assessed by CMR imaging at baseline (Exam 1, 2000–2002), and ten years later (Exam 5, 2010–2012). LACI was defined as the ratio of LA to LV end-diastolic volumes. Univariable and multivariable Cox proportional hazard models were used to evaluate the associations of LACI and average annualized change in LACI (ΔLACI) with incident HF after adjustment on traditional HF risk factors. The incremental risk prediction was calculated using C-statistic, categorical net reclassification index (NRI) and integrative discrimination index (IDI).
RESULTS
Among the 2,250 participants (mean age 59.3 ± 9.3 years and 47.6% male participants), 50 incident HF events occurred over 6.8 ± 1.3 years after the second CMR exam. After adjustment, greater LACI and ΔLACI were independently associated with HF (adjusted HR 1.44, 95% CI [1.25-1.66] and adjusted HR 1.55, 95% CI [1.30-1.85], respectively; both p < 0.0001). Adjusted models for LACI showed significant improvement in model discrimination and reclassification compared to currently used HF risk score model for predicting HF incidence (C-statistic: 0.81 vs. 0.77; NRI = 0.411; IDI = 0.043). After adjustment, ΔLACI showed also significant improvement in model discrimination compared to the multivariable model with traditional HF risk factors for predicting incident HF (C-statistic: 0.82 vs. 0.77; NRI = 0.491; IDI = 0.058).
CONCLUSIONS
In a multi-ethnic population, atrioventricular coupling (LACI) and coupling change (ΔLACI) are independently associated with incident HF. Both have incremental prognostic value for predicting HF over traditional HF risk factors.

BACKGROUND
Several studies have demonstrated the consistently high diagnostic and prognostic value of stress perfusion imaging with cardiovascular magnetic resonance (CMR). The feasibility and the prognostic value of vasodilator stress perfusion CMR in patients with atrial fibrillation (AF) is unknown, because most studies have excluded arrhythmic patients from analysis.
PURPOSE
The aim of our study was to assess the technical feasibility and the prognostic value of vasodilator stress perfusion CMR in patients with AF.
METHODS
Between 2008 and 2018, we prospectively included consecutive patients with AF referred for vasodilator stress perfusion CMR with dipyridamole. They were followed for the occurrence of major adverse cardiovascular events (MACE) defined as cardiac death or non-fatal myocardial infarction (MI). The secondary outcome was all-cause mortality. The diagnosis of AF was confirmed on 12-lead ECG before and after CMR, and patients with sinus rhythm during CMR were excluded. In the CMR protocol, to limit AF-related artifacts on cine images, an arrhythmia rejection algorithm, or real-time sequences were used. Univariable and multivariable Cox regressions for MACE were performed to determine the prognostic value of inducible ischemia or late gadolinium enhancement (LGE) by CMR.
RESULTS
Of 639 patients with AF and suspected or stable chronic CAD (72 ± 9 years, 77% men), 602 (94%) completed the CMR protocol, and among those 538 (89%) completed the follow-up (median follow-up 5.1 (3.3–7.1) years). Reasons for failure to complete CMR included AF-related ECG-gating problems (n = 17), intolerance to stress agent (n = 7), renal failure (n = 6), declining participation (n = 4) and claustrophobia (n = 3).
Stress CMR was well tolerated without occurrence of death or severe disabling adverse event. Patients without inducible ischemia or LGE experienced a substantially lower annual event rate of MACE (1.2%) than those with ischemia and without LGE (8.9%), or those with both ischemia and LGE (9.8%; p < 0.001 for all). Using Kaplan-Meier analysis, the presence of myocardial ischemia identified the occurrence of MACE (hazard ratio HR 7.56 ; 95% confidence interval CI: 4.86 – 11.80; p < 0.001) (Figure).
In a multivariable stepwise Cox regression including clinical characteristics and CMR indexes, the presence of inducible ischemia was an independent predictor of a higher incidence of MACE (HR 5.88 ; 95% CI: 3.70 - 10.07; p < 0.001) and all-cause mortality (HR 2.51 ; 95% CI: 1.47 - 4.17; p < 0.001).
CONCLUSION
Stress CMR is technically feasible and has a good discriminative prognostic value to predict the occurrence of MACE and all-cause mortality in patients with AF.

BACKGROUND
Several studies have demonstrated the consistently high prognostic value of stress perfusion cardiovascular magnetic resonance (CMR). This prognostic value in patients with known myocardial infarction (MI) is poorly described. There remains some skepticism about the capacity of stress CMR in predicting the clinical outcome due to the technical challenge during image analysis causes by myocardial scar.
PURPOSE
The aim of our study was to assess the prognostic value of vasodilator stress perfusion CMR in patients with known MI.
METHODS
We prospectively included consecutive patients with known MI referred for vasodilator stress perfusion CMR with dipyridamole. They were followed for the occurrence of major adverse cardiovascular events (MACE) defined as cardiac death or recurrent non-fatal myocardial infarction (MI). Univariable and multivariable Cox regressions for MACE were performed to determine the prognostic value of inducible ischemia or late gadolinium enhancement (LGE) by CMR.
RESULTS
Of 1602 patients with known MI (68 ± 17 years, 78% men), 1556 (97%) completed the CMR protocol, and among those 1401 (90%) completed the follow-up (median follow-up 5.7 (3.9–7.6) years). Reasons for failure to complete CMR included ECG-gating problems (n = 13), intolerance to stress agent (n = 12), renal failure (n = 12), declining participation (n = 4) and claustrophobia (n = 5). Stress CMR was well tolerated without occurrence of death or severe adverse event. Patients without inducible ischemia experienced a substantially lower annual event rate of MACE (3.1%) than those with 1 or 2 segments of ischemia (4.5%), than those with 3 to 5 segments of ischemia (21.5%), than those with 6 or more segments of ischemia (45.7%, for all p < 0.01). Using Kaplan-Meier analysis, the presence of myocardial ischemia identified the occurrence of MACE (hazard ratio HR 3.52; 95% confidence interval CI: 2.67 – 4.65; p < 0.001). In a multivariable stepwise Cox regression including clinical characteristics and CMR indexes, the presence of inducible ischemia was an independent predictor of a higher incidence of MACE (HR 2.84; 95% CI: 2.14 to 3.78; p < 0.001).
CONCLUSION
Stress CMR is technically feasible and has a good discriminative prognostic value to predict the occurrence of MACE in patients with known MI.

BACKGROUND
Compelling evidence indicates that women with coronary artery disease (CAD) experience worse outcomes than men due to a lack of early diagnosis and management. Numerous clinical studies have shown that stress cardiovascular magnetic resonance (CMR) detects evidence of myocardial ischemia and infarction at high accuracy. However, long-term prognosis data are limited.
PURPOSE
The aim of this study was to test the hypothesis that stress perfusion CMR imaging can provide robust prognostic value in women presenting with suspected ischemia, to the same extent as in men.
METHODS
Consecutive patients referred for vasodilator stress perfusion CMR with dipyridamole were followed for the occurrence of major adverse cardiovascular events (MACE) defined as cardiovascular death or non-fatal myocardial infarction (MI). The secondary endpoint was cardiovascular death. The safety of the CMR was assessed by clinical monitoring for 1 hour after the end of the CMR. Univariable and multivariable Cox regressions for MACE were performed to determine the prognostic value of inducible ischemia or late gadolinium enhancement (LGE) by CMR in each sex.
RESULTS
Of 3436 patients referred for stress CMR in a single French center, 3322 (97%) completed the CMR protocol (59.9 ± 11.8 years, 57% men), and among those 3033 (91%) completed the follow-up (median follow-up 5.4 ± 0.2 years). Reasons for failure to complete CMR included renal failure (n = 29), claustrophobia (n = 26), poor gating (n = 22), intolerance to stress agent (n = 19) and declining participation (n = 18).
Stress CMR was well tolerated without occurrence of death or severe disabling adverse event. Using Kaplan-Meier analysis, the presence of inducible myocardial ischemia identified the occurrence of MACE for both women (hazard ratio HR 2.36 ; 95% confidence interval CI: 1.54–3.62; p < 0.001) and men (HR 3.57 ; 95% confidence interval CI: 2.75 – 4.64; p < 0.001) (Figure). Moreover, inducible ischemia was associated with cardiovascular death for both women (hazard ratio HR 1.92; 95% confidence interval CI: 1.12 – 2.74; p = 0.04) and men (HR 2.71 ; 95% confidence interval CI: 1.98 – 4.41; p < 0.001).
In a multivariable stepwise Cox regression including clinical characteristics and CMR, presence of inducible ischemia was an independent predictor of a higher incidence of MACE for both women (hazard ratio HR 1.85 ; 95% confidence interval CI: 1.18 – 2.92; p = 0.008) and men (HR 3.55 ; 95% confidence interval CI: 2.73 – 4.63; p < 0.001). Moreover, inducible ischemia was associated with cardiovascular death for men (HR 1.99; 95% confidence interval CI: 1.65 – 3.01; p < 0.01) but not for women (p = 0.11).
CONCLUSION
Stress CMR is feasible, safe and has a good discriminative prognostic value to predict the occurrence of MACE in patients of either sex presenting with inducible ischemia. However, inducible ischemia is an independent predictor of a higher incidence of CV mortality only in men.

BACKGROUND
Coronary artery calcifications (CAC) scoring assessed by the Agatston score has shown an excellent prognostic value in large studies, particularly in diabetic patients, with a very low rate of cardiovascular events in patients with a zero Agatston score. Moreover, recent studies have suggested that high-sensitive cardiac troponin I (hs-cTnI) and brain natriuretic peptide (BNP) may be useful for detecting subclinical atherosclerosis, especially in diabetic patients. However, the link between hs-cTnI/BNP and the Agatston score has not been investigated in this population.
PURPOSE
The aim of this study was to investigate if hs-cTnI and BNP can bring additional value to predict zero Agatston score in patients with diabetes mellitus in addition to usual risk factors.
METHODS
Between 2015 and 2019, CAC score was prospectively performed in consecutive patients with diabetes mellitus with high cardiovascular risk. Patients with symptoms or known coronary artery disease were excluded. Within 24h from CT exam, peripheral blood samples were taken to measure hs-cTnI and BNP. The relationship between serum hs-cTnI/BNP concentrations and zero Agatston score was evaluated using univariate and multivariate binomial models. 77 variables have been used to build the model. The implication of hs-cTnI and BNP in this multivariate model was evaluated using nested models associated with Chi-squared test of independence.
RESULTS
A total of 844 patients with diabetes were enrolled (61 ± 7 years, 57% men, mean diabetes duration 18 years). In this population, 294 (35%) had a zero Agatston score, 253 (30%) an Agatston score from 1 to 100, 161 (19%) from 101 to 400, and 136 (16%) higher than 400. In univariate analysis, hs-cTnI and BNP concentrations were associated with a zero Agatston score (respectively OR, 2.63 [95% CI, 1.51-5.01]; p < 0.001 and OR, 1.09 [95% CI, 1.01-1.22]; p = 0.03). In multivariate analysis, hs-cTnI and BNP concentrations were associated with a zero Agatston score (respectively OR, 2.38 [95% CI, 1.51-4.76]; p = 0.009 and OR, 1.18 [95% CI, 1.07-1.32]; p = 0.001). Among the 77 variables, the multivariate model including age, gender, smoking, dyslipidaemia, duration of the diabetes, arterial hypertension, presence of diabetic neuropathy, hs-cTnI and BNP concentrations, significantly discriminated the zero Agatston score (AUC = 0.81; p < 0.001). The most discriminant threshold was ≤ 3ng/l for hs-cTnI and <17ng/l for BNP. In nested models, both hs-cTnI and BNP brought information to this multivariate model to predict a zero Agatston score (respectively p = 0.003 and p < 0.001 to the Chi-squared test). Moreover, removing hs-cTnI and BNP from the model results in a significant reduction in model performance (AUC = 0.79; p = 0.004).
CONCLUSIONS
Cardiac biomarkers hs-cTnI and BNP are associated with a zero Agatston score, which is correlated with a very low risk of cardiovascular events in asymptomatic patients with diabetes mellitus.

BACKGROUND
Guidelines recommend performing a non-invasive testing for ischemia to diagnose coronary artery disease (CAD). However, these tests are frequently inconclusive (25%). This population has been poorly studied because of its heterogeneity. In such cases, stress cardiac magnetic resonance (CMR) may be useful to improve diagnostic certainty. To date, no study has evaluated the prognostic value of stress CMR in these patients presenting with prior inconclusive test.
PURPOSE
To assess the additional prognostic value of vasodilator stress perfusion CMR in patients with a first inconclusive stress test to detect CAD.
METHODS
Between 2008 and 2018, consecutive patients with inconclusive stress test prospectively referred for vasodilator stress perfusion CMR with dipyridamole were followed for major adverse cardiovascular events (MACE) defined as cardiac death or myocardial infarction. Inconclusive stress test was defined by echocardiography or nuclear stress testing with uncertain conclusion about the diagnosis of CAD. To characterize this population, an unsupervised clustering analysis was performed using 18 variables. Univariable and multivariable Cox regressions were performed to determine the prognostic value of inducible ischemia by stress CMR in each cluster.
RESULTS
Of 1502 patients with inconclusive stress test (62 ± 12 years, 59% men), 1441 (96%) completed the CMR protocol and 1397(93%) completed the follow-up (median 5.5 ± 2.3 years). Stress CMR was well tolerated without occurrence of death or severe adverse event. The clustering analysis identified 3 clusters:
Cluster 1 (n = 524, 35%) had the highest prevalence of previous percutaneous coronary intervention (PCI), the highest presence of myocardial scar on CMR, the lowest LVEF(35 ± 7%) and the highest degree of LV dilatation.
Cluster 2 (n = 406, 27%) had the highest prevalence of previous coronary artery bypass grafting (CABG), preserved LVEF(54 ± 10%), absence of LV dilatation and rate of male(89%).
Cluster 3 (n = 572, 38%) had the lowest rate of previous PCI/CABG and of myocardial scar. This cluster gathered the oldest patients (73 ± 11 years), predominantly female (60%), with the highest rate of atrial fibrillation and body mass index.
Survival analysis found significant differences across clusters for the occurrence of MACE (p = 0.02). Moreover, inducible ischemia was significantly associated with the occurrence of MACE in each cluster (cluster 1, HR 2.28; [95%CI: 1.31-3.99]; p = 0.0028; cluster 2, HR 3.37; [95%CI, 1.97-5.75]; p < 0.0001; cluster 3, HR 2.73; [95%CI, 1.67-4.46]; p < 0.0001). In multivariable Cox regression, inducible ischemia was an independent predictor of a higher incidence of MACE in each cluster (p < 0.001).
CONCLUSIONS
Cluster analysis identified 3 different phenotypes of patients with inconclusive stress test that were associated with distinct clinical and prognostic profiles. Within these clusters, CMR stress has an additional prognostic value to predict the occurrence of MACE.
