Abstract Background Ultra long-term (10 years) outcome data of coronary computed tomography angiography (CTA) for coronary heart disease (CHD) screening are lacking. Novel CTA imaging biomarkers (“high-risk-plaque”) may improve risk stratification. Aims To define CT-imaging predictors for long–term outcomes. Methods 1430 low-to-intermediate-risk patients (mean age 57.9 years; 44.4% females) were included into our prospective cohort study. Coronary Calcium Score (CCS) and CTA were performed. CTA was evaluated for: Stenosis severity (minimal<25%; mild<50%; moderate 50–70%; severe >70%) (CADRADS 1–4), total mixed plaque burden (G-score), high–risk-plaque criteria: 1) low attenuation plaque 2) Napkin-ring (“lunar-eclipse” sign) 3) spotty calcification 4) remodeling index Primary endpoint was all-cause mortality, secondary endpoints cardiovascular mortality and composite (non-fatal and fatal) MACE. Results Over a follow-up of mean 10.55 years ±1.98 (range, 6.1–12.8), all-cause mortality rate was 106 (7.4%), cardiovascular mortality 25 (1.75%) and composite MACE 57 (4%). In patients with negative CTA, cardiovascular mortality was 0% and composite MACE rate 0.2%. Stenosis severity (CADRADS) was the strongest predictor for all 3 endpoints (p<0.001) on multivariate analysis (unadjusted and adjusted for risk factors, p<0.001) but calcium score >100 AU only predicted mortality on the unadjusted multivariate analysis (p=0.045) but not on the adjusted. On multivariate analysis, G-score (p<0.0001), LAP<60HU and the Napkin-Ring predicted composite MACE (p<0.001) but not all-cause mortality, before and after adjusting for risk factors (p=0.007 and 0.001 for LAP<60HU and Napkin-Ring, respectively) while spotty calcification and remodeling index did not. 465 had calcium score zero and in 156 (33.5%) of those, noncalcified fibroatheroma were found (total rate, 11%), 4.9% had >50% stenosis. However only 1 patient with calcium score zero died while there were 6 MACE. High risk plaque with “lunar eclipse” Conclusions Long-term prognosis is excellent if CTA is negative. Stenosis severity by CTA predicts all-cause and cardiovascular mortality, while calcium score predicts only mortality. Plaque burden and the high-risk plaque criteria LAP<60 and Napkin-Ring (syn. “lunar eclipse”) are strong predictors of MACE, but not all–cause mortality. Coronary CTA outperforms calcium scoring for risk stratification.

Abstract Background Cardiovascular (CV) risk stratification in patients with end-stage liver disease (ESLD) prior to liver transplantation (LT) is crucial: CV-disease poses a major threat for posttransplant survival. Therefore, our purpose was to assess safety of coronary computed tomographic angiography (CTA) in patients prior to orthotopic LT over a long-term follow up period, and its value for CV risk stratification. Methods In this single center, retrospective observational study 458 patients underwent coronary calcium score (CCS) and coronary CTA for pre-LT risk stratification between 2005 and 2016. CTA was evaluated for 1) stenosis severity (CADRADS: 4-severe>70%/3-intermediate50–70%/2-mild<50%/1-minimal<25%/0=no CAD) 2) plaque burden (SIS, G-score), 3) high–risk plaque features (Napkin Ring Sign, low attenuation plaque, positive remodelling) and 4) Coronary Calcium Score. Primary endpoint was mortality (all-cause and cardiovascular), secondary endpoint major cardiovascular events (MACE). Results Finally 270 patients (79.3% males, age 61±8.5 years) who underwent orthotopic LT were included (mean follow-up 7.5 years±3.1, range 2–13). 87 (32.2%) had CCS zero and 60 (22.2%) CCS >300 Agatston Units (CCS 335.6 AU± 868.9). 248 patients underwent CTA after CCS. The majority had CAD (n=173, 72.3%) by CTA while only 75 (27.7%) had no CAD. 102 patients (38.8%) had minimal-or-mild stenosis<50% (CADRADS 1–2), 34 (12.9%) intermediate and 17 (6.5%) severe stenosis.Out of CCS 0 patients, 13 had non-calcified plaque. All-cause mortality rate was 46 (17.0%), with the majority of patients (43 (93.5%) experiencing non-cardiac death and 3 (6.5%) cardiovascular death due to 1 myocardial infarction and 2 cardiopulmonary failure. CADRADS predicted mortality (Kaplan Meir, p<0.001). On multivariate Cox Regression modell, SIS and G-score predicted all-cause mortality (HR 1.1:p=0.034; 95% CI: 0.649–0.983 and HR 1.1, p=0.029; 95% CI: 1.0–1.6), while Calcium Score did not. There were 6 MACE (3 STEMI, 3 NSTEMI). MACE rate was 0% in CADRADS 0 or 1, 1 in CADRADS-2 and increasing to 5 in CADRADS 3 and 4 groups. Coronary CTA for LT risk stratification Conclusion Cardiac CT is a reliable non-invasive modality for pre-LT assessment of CV-risk over a long-term period, with 0% MACE in patients with no CAD or minimal CAD. CTA allows for an improved CV-risk stratification by stenosis severity (CADRADS) and plaque burden as compared to calcium scoring.

Background: The coronary artery calcium score (CACS) is a powerful tool for cardiovascular risk stratification. Coronary computed tomography angiography (CTA) allows for a more distinct analysis of atherosclerosis. The aim of the study was to assess gender differences in the atherosclerosis profile of CTA in patients with a CACS of zero. Methods: A total of 1451 low- to intermediate-risk patients (53 ± 11 years; 51% females) with CACS <1.0 Agatston units (AU) who underwent CTA and CACS were included. Males and females were 1:1 propensity score-matched. CTA was evaluated for stenosis severity (Coronary Artery Disease – Reporting and Data System (CAD-RADS) 0–5: minimal <25%, mild 25–49%, moderate 50–69%, severe ≥70%), mixed-plaque burden (G-score), and high-risk plaque (HRP) criteria (low-attenuation plaque, spotty calcification, napkin-ring sign, and positive remodeling). All-cause mortality, cardiovascular mortality, and major cardiovascular events (MACEs) were collected. Results: Among the patients, 88.8% had a CACS of 0 and 11.2% had an ultralow CACS of 0.1–0.9 AU. More males than females (32.1% vs. 20.3%; p < 0.001) with a CACS of 0 had atherosclerosis, while, among those with an ultralow CACS, there was no difference (88% vs. 87.1%). Nonobstructive CAD (25.9% vs. 16.2%; p < 0.001), total plaque burden (2.2 vs. 1.4; p < 0.001), and HRP were found more often in males (p < 0.001). After a follow-up of mean 6.6 ± 4.2 years, all-cause mortality was higher in females (3.5% vs. 1.8%, p = 0.023). Cardiovascular mortality and MACEs were low (0.2% vs. 0%; p = 0.947 and 0.3% vs. 0.6%; p = 0.790) for males vs. females, respectively. Females were more often symptomatic for chest pain (70% vs. 61.6%; p = 0.004). (4) Conclusions: In patients with a CACS of 0, males had a higher prevalence of atherosclerosis, a higher noncalcified plaque burden, and more HRP criteria. Nonetheless, females had a worse long–term outcome and were more frequently symptomatic.

Abstract Objective This study sought to analyse the association of early coronary intervention with poor outcomes in patients ≥75 years with NSTEMI. Methods This retrospective observational study included 7811 NSTEMI patients between the years 2005 and 2017; 2451 were older than 75 years old. We compared baseline characteristics according to GRACE risk score. Results We found that 1486 patients (60.6%) underwent early invasive coronary intervention. The long-term all-cause mortality, cardiovascular mortality and MACE differed significantly according to early coronary intervention (HR 0.67, 95% CI: 0.59–0.76; HR 0.64, 95% CI: 0.54–0.74; and HR 0.70, 95% CI: 0.63–0.78, respectively). Conclusion In elderly high-risk NSTEMI patients, early revascularization was associated with reduced all-cause and cardiovascular mortality and MACE.

Abstract Purpose To assess coronary artery disease (CAD) characteristics by coronary CT-angiography (CTA) in individuals with HIV-infection on long-term ART in a retrospective matched case-controlled cohort study. Methods 69 HIV positive patients who underwent 128-slice dual source coronary CTA (mean age 54.9 years, 26.1% females) with mean 17.8±9.4 years of HIV-infection and a mean duration on ART of 13±7.3 years were propensity score matched with 69 HIV negative controls. CTA was evaluated for: Stenosis severity (CAD-RADS), total plaque burden, mixed-non-calcified plaque burden (G-score), high-risk-plaque (HRP) features (Napkin-Ring-Sign, low-attenuation-plaque, spotty calcification, positive remodeling), perivascular fat attenuation index (FAI) and ectatic coronary segments. Results CAD-RADS was higher in HIV-positive participants as compared to controls (2.21±1.4 vs 1.69±1.5, p=0.031). A higher prevalence of CAD and G-score (p=0.043 and p=0.003) were found. HRP prevalence (23 (34.3%) vs 8 (12.1%); p=0.002) and the number of HRP (36 vs 10, p<0.001) were higher in HIV-positive individuals. A positive perivascular FAI >-70 HU was present in 27.8% of HRP. Ectatic coronary arteries were found in 10 (14.5%) individuals with HIV-infection vs 0% in controls (p=0.003). Conclusion(s) HIV positive individuals on long-term ART display higher CAD burden and more HRP indicating vulnerable, potentially inflamed plaques.

Abstract Aims As a consequence of modern urban life, an increasing number of individuals are living alone. Living alone may have potential adverse health implications. The long-term relationship between living alone and all-cause and cardiovascular mortality, however, remains unclear. Methods and results Participants from The Copenhagen Male Study were included in 1985–86 and information about conventional behavioural, psychosocial, and environmental risk factors were collected. Socioeconomic position (SEP) was categorized into four groups. Multivariable Cox-regression models were performed with follow-up through the Danish National Registries. A total of 3346 men were included, mean (standard deviation) age 62.9 (5.2) years. During 32.2 years of follow-up, 89.4% of the population died and 38.9% of cardiovascular causes. Living alone (9.6%) was a significant predictor of mortality. Multivariable risk estimates were [hazard ratio (95% confidence interval)] 1.23 (1.09–1.39), P = 0.001 for all-cause mortality and 1.36 (1.13–1.63), P = 0.001 for cardiovascular mortality. Mortality risk was modified by SEP. Thus, there was no association in the highest SEP but for all other SEP categories, e.g. highest SEP for all-cause mortality 1.01 (0.7–1.39), P = 0.91 and 0.94 (0.6–1.56), P = 0.80 for cardiovascular mortality; lowest SEP 1.58 (1.16–2.19), P = 0.004 for all-cause mortality and 1.87 (1.20–2.90), P = 0.005 for cardiovascular mortality. Excluding participants dying within 5 years of inclusion (n = 274) did not change estimates, suggesting a minimal influence of reverse causation. Conclusions Living alone was an independent risk factor for all-cause and cardiovascular mortality with more than three decades of follow-up. Individuals in middle- and lower SEPs were at particular risk. Health policy initiatives should target these high-risk individuals.

Abstract Background Cardiovascular implantable electronic devices (CIEDs) with physical activity (PA) recording function can continuously and automatically collect patients’ long-term PA data. The dose-response association of implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRTD)-measured PA with cardiovascular outcomes in patients at high risk of sudden cardiac death (SCD) was investigated. Methods In total, 822 patients fulfilling the inclusion criteria were included and divided into three groups according to baseline PA tertiles: tertile 1 (< 8.04%, n = 274), tertile 2 (8.04–13.24%, n = 274), and tertile 3 (> 13.24%, n = 274). The primary endpoint was cardiac death, the secondary endpoint was all-cause mortality. Results During a mean follow-up of 59.7 ± 22.4 months, cardiac death (18.6% vs 8.8% vs 5.5%, tertiles 1–3, P < 0.001) and all-cause mortality (39.4% vs 20.4% vs 9.9%, tertiles 1–3, P < 0.001) events decreased according to PA tertiles. Compared with patients younger than 60 years old, older patients had a lower average PA level (9.6% vs 12.8%, P < 0.001) but higher rates of cardiac death (13.2% vs 8.1%, P = 0.024) and all-cause mortality (28.4% vs 16.7%, P < 0.001) events. Adjusted multivariate Cox regression analyses showed that a higher tertile of PA was associated with a lower risk of cardiac death (hazard ratio (HR) 0.41, 95% confidence interval (CI): 0.25–0.68, tertile 2 vs tertile 1; HR 0.28, 95% CI: 0.15–0.51, tertile 3 vs tertile 1, Ptrend < 0.001). Similar results were observed for all-cause mortality. The dose-response curve showed an inverse non-linear pattern, and a significant reduction in endpoint risk was observed at the low-moderate PA level. The HR for cardiac death was reduced by half with 12.32% PA (177 min), and the HR for all-cause mortality was reduced by half with 11.92% PA (172 min). Subgroup analysis results indicated that older adults could benefit from PA and the range for achieving optimal benefits might be lower. Conclusions PA monitoring may aid in long-term management of patients at high risk of SCD. More PA will generate better survival benefits, but even low-moderate PA is already good especially for older adults, which is relatively easy to achieve.

Abstract RIC with FM has extended the use of HSCT to patients otherwise not eligible for this treatment. Longer follow-up and larger number of patients now allow for more robust evaluation of risk factors and outcomes. Herein are the results of such an evaluation. Patients and Methods: We evaluated outcomes of 112 patients with high-risk AML/MDS treated from August 1996 to December 2003 with FM (fludarabine 100–180 mg/m2 and melphalan 100–180 mg/m2) and unmanipulated HSCT. Eligibility included age &gt;54 yrs. or comorbidity precluding an ablative preparative regimen. Disease status at HSCT was relapsed/refractory (n=43, 38.4%), primary induction failure (n=32, 28.6%), untreated (n=7, 6.3%) or complete remission (CR, n=30, 26.8). Cytogenetic risk was intermediate (n=59, 53%), high (n=47, 42%), low (n=3, 2.5%) or unknown (n=3, 2.5%). Donors were HLA matched related (MRD; n=59) or unrelated (UD; n=53). GVHD prophylaxis was tacrolimus based in all but one patient. Anti-thymocyte-globulin was added in 31 UD HSCT. Stem cell sources were bone marrow (n=56) or peripheral blood (n=57). Median age was 55 (range 22–74). Evaluated were the following variables and their influence on disease progression and overall survival: - age, donor type, duration of first CR, disease status at transplant (categorized as CR, No CR with (NoCR/CB) and without circulating blasts (NoCR/NoCB)), cytogenetics, acute and chronic GVHD (time dependent variables), and blood counts on day 30 (lymphocytes, monocytes and platelets). We used a Cox’s regression analysis. Results: Median time of follow up among survivors (n=43) was 28.4 mo (3.3–88.9). CR rate at day 30 post transplant was 87% (n=97), 8 patients died early and 7 did not respond. 25 (26%) of 97 patients progressed after day 30. All but 3 patients relapsed within the first year post HSCT, and only one relapsed more than 2 years after HSCT. In a landmark analysis, disease status at transplant was the only significant risk factor for progression among these 97 patients (HR of 3.7 for the NoCR/CB group compared to the CR group). 69 of 112 patients died with a median survival of 4.6 mo. Seven deaths (10% of all deaths) were observed more than 2 yrs. after HSCT, due to GVHD (n=3), infection (n=2), relapse (n=1) and unknown causes (n=1). Two-year OS and PFS was 44% and 69% respectively. Disease status at HSCT and grade II-IV aGVHD were the only significant predictors of OS on univariate and multivariate analysis. Blood counts on day 30 were associated with disease status at transplant, donor type and aGVHD. Their independent effect on outcome could not be evaluated given sample size. Conclusion: A significant portion of older patients with high-risk AML/MDS may achieve long-term PFS, but early relapses are the major cause of treatment failure in this context.

Additional Value

The efficacy of CRT (cardiac resynchronization therapy) can be affected by a number of factors; however, the prognostic significance of the LV (left ventricular) lead position has not been explored. The aim of the present study was to examine whether a PL (posterolateral) lead position has an additional value to systolic dyssynchrony in predicting a better survival after CRT. Patients (n=134) who received CRT were followed-up for 39±24 months. The LV lead position was determined by cine fluoroscopy, and baseline dyssynchrony was assessed by TDI (tissue Doppler imaging). The relationship between the LV lead position/dyssynchrony and mortality was compared using Kaplan–Meier curves, followed by Cox regression analysis. The all-cause and cardiovascular mortalities were 38 and 31% respectively. The presence of dyssynchrony and a PL lead position predicted a lower all-cause mortality (29 compared with 47%; log-rank χ2=5.38, P=0.02) and cardiovascular mortality (21 compared with 41%; log-rank χ2=6.75, P=0.009) than when absent. The all-cause mortality was as high as 62% when patients had neither dyssynchrony nor a PL lead position, but was reduced to 29% when both criteria were present, and was between 45 and 46% when only one criterion was present (χ2=6.79, P=0.01). The corresponding values for cardiovascular mortality were 62% when patients had neither dyssynchrony nor a PL lead position, 36–38% when patients had either dyssynchrony or a PL lead position, and 21% when patients had both criteria present (χ2=9.54, P=0.004). Combining dyssynchrony and a PL lead position independently predicted a lower all-cause morality {HR (hazard ratio), 0.496 [95% CI (confidence interval), 0.278–0.888]; P=0.018} and cardiovascular mortality [HR, 0.442 (95% CI, 0.232–0.844); P=0.013]. In conclusion, the placement of the LV lead at a PL position provides additional value to baseline dyssynchrony in predicting a lower all-cause and cardiovascular mortality during long-term follow-up after CRT.
