Abstract Background: Hyperuricemia is associated with an increased risk of cardio-and cerebrovascular disease (CVD) in general population. However, in the hemodialysis (HD) patients, low serum uric acid (SUA) increases the risk of mortality. Considering that CVD is the principal cause of death among maintenance HD patients, the present study aimed to determine the predictive value of SUA for CVD outcome in this population. Methods: In this two-year follow-up prospective study, 205 outpatients under maintenance HD were enrolled from March 2017 to 2020. Patients’ demographic data, underlying diseases, and the results of serum tests, as well as two-year follow-up results of CVD events and mortality were recorded. Results: A total of 130 (63%) patients were eligible for analysis; 62.9% were male; mean age of participants was 59±13years. At follow-up, coronary artery disease was observed in 43.2%, peripheral artery disease in 26.5%, and cerebrovascular disease in 20.5%; angiography was required in 52.3% and 4.5% died of CVD. SUA was ≤5.4 mg/dL in 52 patients, 5.5-6.1 mg/dL in 19, and ≥6.2 mg/dL in 59 patients with significant difference based on mean age, sex distribution, occurrence of cerebrovascular disease and cardiovascular mortality (P<0.05). Patients with cerebrovascular disease had a significantly lower SUA levels (P=0.006). Logistic regression showed the significant effect of SUA on the occurrence of cerebrovascular disease (P=0.008). Conclusion: Low SUA can predict two-year incidence of cerebrovascular disease in HD patients. However, SUA levels did not show significant predictive effect on two-year coronary events, peripheral artery disease and cardiovascular mortality.

Background The relationship between body mass index (BMI) and mortality in patients with established arterial disease remains controversial. Methods FRENA is an ongoing, observational registry of consecutive outpatients with coronary artery disease (CAD), cerebrovascular disease, or peripheral artery disease (PAD). We examined the prognostic importance of accepted BMI categories on outcome among patients in the FRENA registry. Results In April 2008, 2274 patients (mean age, 66 years) had been enrolled, of whom 14 (0.6%) were underweight; 533 (23%) normal; 1051 (46%) overweight; and 676 (30%) were obese. Over a mean follow-up of 14 months, the incidence of major cardiovascular events (myocardial infarction, ischemic stroke, or critical limb ischemia) per 100 patient-years was: 7.1 [95% confidence interval (CI): 0.4–35]; 11 (95% CI: 8.4–14); 6.9 (95% CI: 5.6–8.5); and 8.5 (95% CI: 6.6–11), respectively. Their cardiovascular mortality was: 7.1 (95% CI: 0.4–35); 4.1 (95% CI: 5.9–11); 1.3 (95% CI: 0.9–2.3); and 1.5 (95% CI: 1.4–3.5), respectively. On multivariate analysis, the hazard ratio for cardiovascular mortality was: 2.2 (95% CI: 0.3–17); 1.0 (reference); 0.37 (95% CI: 0.20–0.69); and 0.37 (95% CI: 0.18–0.73), respectively. Survival benefit was only found in patients with CAD or PAD. Weight loss had little influence on outcome. Conclusion Patients with CAD or PAD (not those with cerebrovascular disease) have an inverse correlation between BMI and cardiovascular mortality, even after adjusting for confounding variables.

The burden and predictors of hospitalization over time in community-based patients with peripheral artery disease (PAD) have not been established. This study evaluates the frequency, reasons and predictors of hospitalization over time in community-based patients with PAD. We assembled an inception cohort of 1798 PAD cases from Olmsted County, MN, USA (mean age 71.2 years, 44% female) from 1 January 1998 through 31 December 2011 who were followed until 2014. Two age- and sex-matched controls ( n = 3596) were identified for each case. ICD-9 codes were used to ascertain the primary reasons for hospitalization. Patients were censored at death or last follow-up. The most frequent reasons for hospitalization were non-cardiovascular: 68% of 8706 hospitalizations in cases and 78% of 8005 hospitalizations in controls. A total of 1533 (85%) cases and 2286 (64%) controls ( p < 0.001) were hospitalized at least once; 1262 (70%) cases and 1588 (44%) controls ( p < 0.001) ≥ two times. In adjusted models, age, prior hospitalization and comorbid conditions were independently associated with increased risk of recurrent hospitalizations in both groups. In cases, severe PAD (ankle–brachial index < 0.5) (HR: 1.25; 95% CI: 1.15, 1.36) and poorly compressible arteries (HR: 1.26; 95% CI: 1.16, 1.38) were each associated with increased risk for recurrent hospitalization. We demonstrate an increased rate of hospitalization in community-based patients with PAD and identify predictors of recurrent hospitalizations. These observations may inform strategies to reduce the burden of hospitalization of PAD patients.

Abstract Background: Studies on the correlation between serum uric acid (SUA) and all-cause mortality in peritoneal dialysis (PD) patients were mainly based on the results of baseline SUA. We aimed to analyze the change of SUA level post PD, and the correlation between follow-up SUA and prognosis in PD patients. Methods: All patients who received PD catheterization and maintaining PD in our center from March 2, 2001 to March 8, 2017 were screened. Kaplan-Meier and Cox proportional-hazards regression models were used to analyze the effect of SUA levels on the risks of death. We graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months post PD by mean of SUA plus or minus a standard deviation as cut-off values, and compared all-cause and cardiovascular mortality among patients with different SUA grades. Results: A total of 1402 patients were included, 763 males (54.42%) and 639 females (45.58%). Their average age at PD start was 49.50±14.20 years. The SUA levels were 7.97±1.79mg/dl at baseline, 7.12±1.48mg/dl at 6 months, 7.05±1.33mg/dl at 12 months, 7.01±1.30mg/dl at 18 months, and 6.93±1.26mg/dl at 24 months. During median follow-up time of 31 (18, 49) months, 173 (12.34%) all-cause deaths occurred, including 68 (4.85%) cardiovascular deaths. There were no significant differences on all-cause mortality among groups with graded SUA levels at baseline, 12 months, 18 months and 24 months during follow-up or on cardiovascular mortality among groups with graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months during follow-up. At 6 months post PD，Kaplan Meier analysis showed there was significant difference on all-cause mortality among graded SUA levels (c2=11.315, P=0.010), and the all-cause mortality was lowest in grade of 5.65mg/dl≤SUA<7.13mg/dl. Conclusion: SUA level decreased during follow up post PD. At 6 months post PD, a grade of 5.65mg/dl≤SUA<7.13mg/dl was appropriate for better patients’ survival.

Abstract Background: Peripheral artery disease (PAD) represents one of the most relevant vascular complications of type 2 diabetes mellitus (T2DM). Moreover, T2DM patients suffering from PAD have an increased risk of major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Sortilin, a protein involved in apolipoproteins trafficking, is associated with lower limb PAD in T2DM patients.Objective: To evaluate the relationship between baseline serum levels of sortilin, MACE and MALE occurrence after revascularization of T2DM patients with PAD and chronic limb-threatening ischemia (CLTI).Research Design and Methods: We performed a prospective non-randomized study including 230 statin-free T2DM patients with PAD and CLTI. Sortilin levels were measured before the endovascular intervention and incident outcomes were assessed during a 12-month follow-up.Results: Sortilin levels were significantly increased in individuals with more aggressive PAD (2.25 ± 0.51 ng/mL vs 1.44 ± 0.47 ng/mL, p < 0.001). During follow-up, 83 MACE and 116 MALE occurred. In patients, who then developed MACE and MALE, sortilin was higher. In particular, 2.46 ± 0.53 ng/mL vs 1.55 ± 0.42 ng/mL, p < 0.001 for MACE and 2.10 ± 0.54 ng/mL vs 1.65 ± 0.65 ng/mL, p < 0.001 for MALE. After adjusting for traditional atherosclerosis risk factors, the association between sortilin and vascular outcomes remained significant in a multivariate analysis. In our receiver operating characteristics (ROC) curve analysis using sortilin levels the prediction of MACE incidence improved (area under the curve [AUC] = 0.94) and MALE (AUC = 0.72).Conclusions: This study demonstrates that sortilin correlates with incidence of MACE and MALE after endovascular revascularization in a diabetic population with PAD and CLTI.

Research design and methods We performed a prospective non-randomized study including 230 statin-free T2DM patients with PAD and CLTI. Sortilin levels were measured before the endovascular intervention and incident outcomes were assessed during a 12 month follow-up. Results Sortilin levels were significantly increased in individuals with more aggressive PAD (2.25 ± 0.51 ng/mL vs 1.44 ± 0.47 ng/mL, p < 0.001). During follow-up, 83 MACE and 116 MALE occurred.

Abstract Aims The detection of cardiac valvular calcification on routine imaging may provide an opportunity to identify individuals at increased risk for peripheral artery disease (PAD). We investigated the associations of aortic valvular calcification (AVC) and mitral annular calcification (MAC) with risk of developing clinical PAD or a low ankle–brachial index (ABI). Methods and results AVC and MAC were measured on cardiac computed tomography in 6778 Multi-Ethnic Study of Atherosclerosis participants without baseline PAD between 2000 and 2002. Clinical PAD was ascertained through 2015. Incident low ABI, defined as ABI &lt;0.9 and decline of ≥0.15, was assessed among 5762 individuals who had an ABI &gt;0.9 at baseline and at least one follow-up ABI measurement 3–10 years later. Adjusted Cox proportional hazards and Poisson regression modelling were used to determine the association of valvular calcification with clinical PAD and low ABI, respectively. There were 117 clinical PAD and 198 low ABI events that occurred over a median follow-up of 14 years and 9.2 years, respectively. The presence of MAC was associated with an increased risk of clinical PAD [hazard ratio 1.79; 95% confidence interval (CI) 1.04–3.05] but not a low ABI (rate ratio 1.28; 95% CI 0.75–2.19). No significant associations were noted for the presence of AVC and risk of either clinical PAD. Conclusion MAC is associated with an increased risk of developing clinical PAD. Future studies are needed to corroborate our findings and better understand whether MAC holds any predictive value as a risk marker for PAD.

Background: Current guidelines recommend aggressive management of hypertension. Recent evidence suggested potential harm with low blood pressure targets in patients with peripheral artery disease. We investigated the association of a history of hypertension and office systolic blood pressure (SBP) with major adverse cardiovascular events (MACEs) and major adverse limb events (MALEs). Methods and Results: The EUCLID trial (Examining the Use of Ticagrelor in Peripheral Artery Disease) included 13 885 participants with symptomatic peripheral artery disease; median follow-up was 30 months. Cox proportional hazards regression was used to calculate hazard ratios (HRs) for any MACE, MALE, and MALE including lower extremity revascularization. A clinical history of arterial hypertension was present in 10 857 (78%) participants, and these participants were older and more likely to be female when compared with the 3026 (22%) patients without hypertension. In patients with a history of hypertension, the adjusted hazard ratio for MACE was 0.94, 95% CI, 0.82–1.08; P =0.39, and the adjusted hazard ratio for MALE was 1.08, 95% CI, 0.96–1.23; P =0.21. During follow-up, average SBP was 135 mm Hg (125–145). Every 10 mmHg increase in SBP>125 mmHg was associated with an increased risk of MACE (HR, 1.10 [95% CI, 1.06–1.14]; P <0.001), a marginally increased risk of MALE (HR, 1.07 [95% CI, 1.00–1.15]; P =0.062), and an increased risk of MALE/lower extremity revascularization (HR, 1.08 [95% CI, 1.04–1.11]; P <0.001). Every decrease in 10 mmHg SBP ≤125 mmHg was associated with an increased risk of MACE (HR, 1.19 [95% CI, 1.09–1.31]; P <0.001) but not MALE or MALE/lower extremity revascularization (HR, 1.02 [95% CI, 0.84–1.23], P =0.824; HR, 1.04 [95% CI, 0.95–1.13], P =0.392, respectively). Conclusions: History of hypertension was not associated with higher hazard for MACE or MALE in patients with peripheral artery disease. In contrast, there was a higher hazard of MACE in patients with out-of-target low and high SBP. High but not low SBP was associated with an increased risk of ischemic limb events.

AbstractPeripheral artery disease (PAD) has been shown to be linked to elevated cardiovascular risk. The novel T50 test quantifies calcification propensity of serum and has been associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD) and in the general population. This study investigated the association of calcification propensity measured by the T50 test in 287 patients with PAD without severe CKD. Major cardiovascular events (MACEs) including nonfatal stroke and nonfatal myocardial infarction and all-cause death (MACE + ) were evaluated after a median follow-up of 4 years and long-term cardiovascular and all-cause mortality after a median follow-up of 8.7 years by Kaplan–Meier and Cox regression analyses. Mean T50 time was 268 ± 63 minutes in the study cohort (age 69 ± 10 years, 32% women, 47% diabetes). Low T50 values that signify high calcification propensity were significantly associated with the occurrence of MACE+ (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.55–0.94). This association sustained multivariate adjustment for cardiovascular risk factors (CVRFs), Fontaine PAD stage, and prevalent media sclerosis (HR: 0.65; CI: 0.47–0.91). Cardiovascular mortality was significantly associated with T50 after multivariate adjustment for CVRF (HR: 0.72; CI 0.53–0.99), but not all-cause mortality (HR: 0.80; CI: 0.64–1.01). In conclusion, calcification propensity associates with MACE+ and cardiovascular mortality in patients with PAD.
