Abstract Background and Aims It is estimated that Chronic Kidney Disease (CKD) accounts for 5 to 10 million deaths annually, mainly due to cardiovascular (CV) diseases. Although traditional CV risk factors are prevalent, other non-traditional CV risk factors such as vascular calcification (VC) are believed to contribute to this disproportionate CV risk burden in CKD subjects. We sought to investigate the association of Coronary Artery Calcification (CAC) progression with all-cause mortality in a cohort of patients new to hemodialysis (HD). Method This is a post hoc analysis of the Independent study (NCT00710788) originally designed to test the impact of 2 different phosphate binder regimens on various hard as well as surrogate endpoint in HD subjects. A total of 412 (88.4% of the Independent study cohort) underwent repeated CAC quantification according to the Agatston methods at study inception as well as after 12 months of follow-up. The square root method was used to assess CAC progression (CACP) and survival analyses were used to check the association of CACP and all-cause mortality. Results 412 middle age (65 years) men and women (51.2%) were considered. Detectable CAC was present in about 2 out 3 patients (68.2%) at study inception. At 12 months of follow-up completion, about 1 out of 3 subjects (33.1%) experience a significant CACP. CACP was associated with older age and use of calcium-based phosphate binders. At study completion (median follow-up: 36 months) 106 patients expired of all-cause. Age, diabetes mellitus, atherosclerotic CV events, baseline CAC extension were predictors of unfavorable outcome. Multivariable adjusted analysis confirmed an independent association of both baseline CAC (Hazard Ratio 1.29; 95% Confidence Interval: 1.17-1.44) and CACP (HR: 5.16; 95%CI: 2.61-10.21) with all-cause mortality. However, CACP diminished the risk associated with baseline CAC (p for interaction term 0.002) and use of calcium-free phosphate binders significantly weakened the link between CACP (HR. 1.95; 95%CI: 0.92-4.16) and mortality Conclusion Baseline CAC as well as CACP predict mortality in incident to HD individuals. Nevertheless, CACP mitigates the risk associated with baseline CAC and calcium-free phosphate binders attenuates the association of CACP and mortality, suggesting that CACP modulation may impact survival in this population

The Impact

The most relevant comorbidities in patients with peripheral artery disease (PAD) are coronary artery disease (CAD) and diabetes mellitus (DM). However, data of long-term follow-up of patients with chronic total occlusion (CTO) are scarce. The aim of the study was to assess the impact of CAD and DM on long-term follow-up patients after superficial femoral artery (SFA) CTO retrograde recanalization. In this study, eighty-six patients with PAD with diagnosed CTO in the femoropopliteal region and at least one unsuccessful attempt of antegrade recanalization were enrolled in 2 clinical centers. Mean time of follow-up in all patients was 47.5 months (±40 months). Patients were divided into two groups depending on the presence of CAD (CAD group: n=45 vs. non-CAD group: n=41) and DM (DM group: n=50 vs. non-DM group: n=36). In long-term follow-up, major adverse peripheral events (MAPE) occurred in 66.6% of patients with CAD vs. 36.5% of patients without CAD and in 50% of patients with DM vs. 55% of non-DM subjects. There were no statistical differences in peripheral endpoints in both groups. However, there was a statistically significant difference in all-cause mortality: in the DM group, there were 6 deaths (12%) (P value = 0.038). To conclude, patients after retrograde recanalization, with coexisting CTO and DM, are at higher risk of death in long-term follow-up.

e18715 Background: Pts with hem diseases are at high risk of COVID-19 severe course and mortality. Emerging data on risk factors and outcomes in this patient population is of great value for developing strategies of medical care. Methods: CHRONOS19 is an ongoing nationwide observational cohort study of adult (≥18 y) pts with hem disease (both malignant and non-malignant) and lab-confirmed or suspected (clinical symptoms and/or CT) COVID-19. Primary objective was to evaluate treatment outcomes. Primary endpoint was 30-day all-cause mortality. Long-term follow-up was performed at 90 and 180 days. Data from 14 centers was collected on a web platform and managed in a deidentified manner. Results: As of data cutoff on January 27, 2021, 575 pts were included in the registry, 486 of them eligible for primary endpoint assessment, n(%): M/F 243(50%)/243(50%), median age 56 [18-90], malignant disease in 452(93%) pts, induction phase/R/R/remission 160(33%)/120(25%)/206(42%). MTA in 93(19%) pts, 158(33%) were transfusion dependent, comorbidities in 278(57%) pts. Complications in 335(69%) pts: pneumonia (67%), CRS (8%), ARDS (7%), sepsis (6%). One-third of pts had severe COVID-19, 25% were admitted to ICU, 20% required mechanical ventilation. All-cause mortality at 30 days – 17%; 80% due to COVID-19 complications. At 90 days, there were 14 new deaths: 6 (43%) due to hem disease progression. Risk factors significantly associated with OS are listed in Tab 1. In multivariate analysis – ICU+mechanical ventilation, HR, 53.3 (29.1-97.8). Acute leukemias were associated with higher risk of death, HR, 2.40 (1.28-4.51), less aggressive diseases (CML, CLL, MM, non-malignant) – with lower risk of death, HR, 0.54 (0.37-0.80). No association between time of COVID-19 diagnosis (Apr-Aug vs. Sep-Jan) and risk of death. COVID-19 affected treatment of hem disease in 65% of pts, 58% experienced treatment delay for a median of 4[1-10] weeks. Relapse rate on Day 30 and 90 – 4%, disease progression on Day 90 detected in 13(7%) pts; 180-day data was not mature at the time of analysis. Several cases of COVID-19 re-infection were described. Conclusions: Thirty-day all-cause mortality in pts with hem disease was higher than in general population with COVID-19. Longer-term follow-up (180 days) for hem disease outcomes and OS will be presented. [Table: see text]

Introduction: Recent studies have suggested that extreme levels of physical activity (endurance athletes) are associated with subclinical atherosclerosis as well as increased mortality. The safety of continuing high levels of physical activity is uncertain once coronary artery calcification (CAC) is discovered. Hypothesis: We hypothesized that men performing &ge3000 MET·minutes/week of physical activity would have greater all-cause and cardiovascular (CV) mortality compared to those with &lt1500 or 1500-&lt3000 MET·minutes/week of physical activity and that mortality risk would be greater in those with CAC&ge100 compared to &lt100 Agatston units. Methods: The cohort studied included 16,109 men without prevalent CV disease who reported physical activity levels and underwent EBT or MDCT scan. Physical activity was categorized into &ge3000 (n=1,266), 1500-3000 (n=3,027), and &lt1500 (n=11,816) MET·minutes/week. CAC scanning included EBT scans (1997-2007) or MDCT scans (2007-2013), and CAC score was categorized into &ge100 (n=3,547) and &lt100 (n=12,562) Agatston units. We fit separate proportional hazards regression models to follow-up times for all-cause and CV mortality. The models included all combinations of CAC and physical activity categories and were adjusted for baseline age, smoking, BMI, cholesterol, HDLc, and systolic blood pressure. Results: The average age of participants at baseline was 51.3±8.3 years. Men with the highest activity level had a lower BMI and higher HDLc. After an average follow-up of 8.9 years, there were 329 all-cause and 60 CV deaths, including 174 all-cause and 38 CV deaths in those with CAC&ge100. The sample had 80% power to detect all-cause mortality hazard ratios &ge 1.9 and 1.8 for physical activity &ge3000 versus &lt1500 in those with CAC&lt100 and &ge100, respectively. The corresponding minimum detectable CV mortality hazard ratios were 3.5 and 2.8. Comparing physical activity &ge3000 to &lt1500 in those with CAC&ge100, the hazard ratios (95% CI) were 0.9 (0.5, 1.5) for all-cause mortality and 0.9 (0.3, 3.1) for CV mortality. Hazard ratios were similar when comparing physical activity &ge3000 to 1500-&lt3000 in those with CAC &ge100. Finally, when comparing physical activity categories, there was no evidence that hazard ratios varied by CAC category, p&gt0.7. Conclusions: This sample offers no evidence that levels of activity &ge3000 MET·minutes/week are associated with increased all-cause or CV mortality compared to those with &lt1500 or 1500- &lt3000 MET·minutes/week, regardless of CAC level.

Abstract Background Dyslipidemia is a well-known risk factor for cardiovascular disease (CVD). Recently, atherogenic index of plasma (AIP) has been proposed as a novel predictive marker for CVD, and there are few cross sectional studies that demonstrated a relationship between AIP and coronary artery disease. We investigated the association between AIP and the progression of coronary artery calcification (CAC) in Korean adults without CVD. Methods A total of 1,124 participants who had undergone CAC measurement at least twice by multi-detector CT in a health care center were enrolled. Anthropometric profiles and multiple cardiovascular risk factors were assessed. The AIP was defined as the base 10 logarithm of the ratio of the concentration of TG to HDL-C. The CAC progression was defined as either incident CAC in a CAC-free population at baseline or an increase of ≥ 2.5 units between the square roots of the baseline and follow-up coronary artery calcium scores (CACS) among subjects with detectable CAC at baseline Results CAC progression was observed in 290 subjects (25.8%) during the mean 4.2 years of follow-up. All subjects were stratified into three groups according to AIP. There were significant differences in cardiovascular parameters among the groups at baseline. The follow-up CAC and the incidence of CAC progression increased gradually with the rising AIP tertiles. In the logistic regression analysis, the odds ratio for CAC progression was 2.27 when comparing the highest to the lowest tertile of the AIP (95% CI: 1.61-3.19; P for trend <0.01). However, this association was attenuated after adjustment for multiple risk factors (P for trend = 0.67). Conclusions There is a significant correlation between AIP and CAC and its progression in subjects without CVD, but AIP is not an independent predictor of CAC progression.

AbstractThis study aimed to evaluate the association between the atherogenic index of plasma (AIP), which has been suggested as a novel marker for atherosclerosis, and coronary artery calcification (CAC) progression according to the baseline coronary artery calcium score (CACS). We included 12,326 asymptomatic Korean adults who underwent at least two CAC evaluations from December 2012 to August 2016. Participants were stratified into four groups according to AIP quartiles, which were determined by the log of (triglyceride/high-density lipoprotein cholesterol). Baseline CACSs were divided into three groups: 0, 1 − 100, and > 100. CAC progression was defined as a difference ≥ 2.5 between the square roots (√) of the baseline and follow-up CACSs (Δ√transformed CACS). Annualized Δ√transformed CACS was defined as Δ√transformed CACS divided by the inter-scan period. During a mean 3.3-year follow-up period, the overall incidence of CAC progression was 30.6%. The incidences of CAC progression and annualized Δ√transformed CACS were markedly elevated with increasing AIP quartile in participants with baseline CACSs of 0 and 1 − 100, but not in those with a baseline CACS > 100. The AIP level was associated with the annualized Δ√transformed CACS in participants with baseline CACSs of 0 (β = 0.016; P < 0.001) and 1 − 100 (β = 0.035; P < 0.001), but not in those with baseline CACS > 100 (β = 0.032; P = 0.385). After adjusting for traditional risk factors, the AIP was significantly associated with CAC progression in those with baseline CACS ≤ 100. The AIP has value for predicting CAC progression in asymptomatic adults without heavy baseline CAC.

Abstract Background Although progression of coronary artery calcification (CAC) has been established as an important marker for cardiovascular morbidity, very few studies have studied it in end-stage renal disease patients. Thus we examined and evaluate risk factors of calcification changes in dialysis patients. Method Among 28 hemodialysis (HD) patients, CAC was measured in Agatston units at baseline and after five years using the 64 multi-slice ultra-fast CT. The HD patients were classified as progressors or no progressors according to the change in the CAC score across these 2 measurements. Results Over an average 63 months follow-up, participants without CAC at baseline had no incident CAC .The progression of CAC was slow and was found only in 6 patients (21.4%) . It was significantly associated with several cardiovascular risk factors, namely, older age (p=0.03), diabetes (p=0.05), male sex (p=0.02), hypercholesterolemia (p = 0.05), anemia (p=0.017), inflammation (p=0.05), and hyperphosphataemia (p=0.012) . However, calcemia, parathormone levels, dialysis duration, tobacco, high blood pressure and dialysis dose did not seem to influence the progression of CAC in our series. A strong association was found between basal calcification scores and Delta increment at 5 years. Conclusions Our study suggests that CAC progression in dialysis is a complex phenomenon, associated with several risk factors with special regard to elevated basal scores. This progression can be avoided or slowed with appropriate management which must begin in the early stages of chronic kidney disease

Background: Myocardial bridging (MB) is frequently seen on coronary CT angiography (CCTA). However, there has been conflicting data on the prognostic value of MB. The aim of this analysis is to determine the prognostic value of MB in patients without obstructive coronary artery disease (CAD) (<50 diameter stenosis). Methods: We included patients with no known prior coronary artery disease (CAD) who underwent CCTA for various clincial reasons. Patients with obstructive CAD on CCTA were excluded. The study cohort was followed for all cause mortality or myocardial infarction (MI) (median follow-up 1.7 years). Group comparisons were made between patients with patients with or without MB. Results: A total of 715 patients were included in this analysis of which 68 patients had MB (10%). 73% of the bridges were in the mid LAD and 22% had bridging in the distal LAD. 48% of the study cohort had normal coronaries, while 52% had evidence of non obstructive CAD. There were no differences in the baseline characteristics, symptomatic status or prevalence of non obstructive CAD between the two groups (all p>0.5). After a median follow-up duration of 1.7 years, 23 patients died and 10 patients experienced myocardial infarction. There were no statistically significant differences in the rate of death/MI between the two groups (figure). Using multivariable Cox regression, the presence of MB was not associated with increased risk for death/MI (Adjusted HR 0.4, 95% confidence interval 0.1 -2.8, p=0.34) Conclusions: In patients with non-obstructive CAD, MB is not associated with increased risk for all cause death or MI.

Introduction: Coronary artery calcification (CAC) is prevalent among patients with chronic kidney disease (CKD) and predicts the risk of cardiovascular disease (CVD). Risk factors for the progression of CAC in patients with CKD have not been well studied. Hypothesis: We assessed the hypothesis that several established and novel CVD risk factors are associated with progression of CAC among patients with CKD. Methods: In a random subsample of 1,123 participants from the Chronic Renal Insufficiency Cohort (CRIC) Study, CAC was measured at baseline and the follow-up visit using electron beam computed tomography (CT) or multidetector CT. CAC progression was defined as an increase of Agatston score ≥100 units during follow-up. Multiple logistic regression and mixed-effects regression models were used to assess risk factors for progression of CAC. Results: Over an average of 3-year follow-up, 332 (29.6%) participants developed CAC progression. After adjusting for age, sex, race, clinical site, total cholesterol, HDL-cholesterol, systolic blood pressure, antihypertensive treatment, diabetes, and current smoking in the multivariable models, history of CVD (odds ratio [OR] 1.53, 95% CI 1.09-2.15, p=0.02), lipid-lowering treatment (OR 1.81, 95% CI 1.28-2.55, p<0.001), higher serum phosphate (OR 1.37, 95% CI 1.17-1.61, p<0.001), hemoglobin A1c (OR 1.32, 95% CI 1.10-1.58, p=0.002), and cystatin C (OR 1.24, 95% CI 1.06-1.45, p=0.007), and lower estimated-glomerular filtration rate (eGFR) (OR 1.32, 95% CI 1.10-1.56, p=0.002) were associated with CAC progression. In addition, lower physical activity, lipid-lowering treatment, body-mass index, LDL-cholesterol, lower serum calcium, phosphate, total parathyroid hormone, fibrinogen, interleukin-6, tumor necrosis factor-α, fibroblast growth factor-23, lower eGFR, cystatin C, and 24-hour urine albumin were associated with square root transformed change in CAC score from baseline in multiple-adjusted models. These findings persisted after additional adjustment for baseline CAC score. Conclusions: In conclusion, these data suggest that reduced kidney function, calcium and phosphate metabolic disorders and inflammation, in addition to established CVD risk factors, might play a role in CAC progression among patients with CKD.

Background: Vascular calcification (VC) is a marker of cardiovascular (CV) disease and various methods allow for presence and extension assessment in different arterial districts. Nevertheless, it is currently unclear which one of these methods for VC evaluation best predict outcome and if this piece of information adds to the predictive value of traditional CV risk factors in patients receiving hemodialysis (HD). Methods: data of 184 of the 466 patients followed in the Independent study (NCT00710788) were post hoc examined to assess the association three concurrent measures of vascular calcification and all-cause survival. Specifically, coronary artery calcification (CAC) was determined by the Agatston and the volume score while abdominal aorta calcification was determined by plain X-ray of the lumbar spine (Kauppila score (KS)). Survival and regression models as well as metrics of risk recalculation were used to test the association of VC and outcome beyond the Framingham risk score. Results: Middle-age (62.6(15.8) years) men (51%) and women (49%) starting HD were analyzed. Over 36 (median 36; interquartile range: 8–36) months of follow-up 69 patients expired. Each measure of VC (CAC or KS) predicted all-cause mortality independently factors commonly associated with all-cause survival (p < 0.001). Far more importantly, each measurement of VC significantly improved risk prediction and patient reclassification (p < 0.001) beyond traditional cardiovascular risk factors. Conclusions: Overall, presence and extension of VC, irrespective of the arterial site, predict risk of all-cause of death in patients starting hemodialysis. Of note, both CAC and KS increase risk stratification beyond traditional CV risk factors. However, future efforts are needed to assess whether a risk-based approach encompassing VC screening to guide HD patient management improves survival.
