Abstract:
Background Red cell distribution width (RDW) and neutrophil-to-lymphocyte ratio (NLR) are simple hematologic indices that have been used to predict adverse outcomes in different clinical settings. The aim of our study is to determine whether RDW and NLR can predict atrial fibrillation (AF) recurrence in patients undergoing AF ablation. Methods Consecutive patients, without known hematological disorders, who underwent AF catheter ablation between January 2014 and April 2017 were enrolled into this study. Blood samples were taken one day before and five hours after the ablation procedure. Results A total of 346 patients (224 males (65%), mean age: 59 ± 11 years old) were included. After a mean follow up of 26.2 ± 12.1 months, 80 (23.1%) patients experienced late AF recurrence (defined as any recurrence after the blanking period of three months), while 97 (28%) patients experienced early AF recurrence during the blanking period. Univariate analysis showed that early arrhythmia recurrence, type of AF and NLR after the procedure were significantly associated with late AF recurrence, while early arrhythmia recurrence and NLR remained significant in multivariate analysis. RDW was not associated with late AF recurrence. None of the parameters above predicted early arrhythmia recurrence. Conclusions Simple and inexpensive hematological indices such as NLR should be evaluated for their ability to predict AF recurrence in patients undergoing catheter ablation in larger prospective studies.

Abstract:
Background Combinations of coronary heart disease (CHD) and other chronic conditions complicate clinical management and increase healthcare costs. The aim of this study was to evaluate gender-specific relationships between CHD and other comorbidities. Methods We analyzed data from the German Health Interview and Examination Survey (DEGS1), a national survey of 8152 adults aged 18?79 years. Female and male participants with self-reported CHD were compared for 23 chronic medical conditions. Regression models were applied to determine potential associations between CHD and these 23 conditions. Results The prevalence of CHD was 9% (547 participants): 34% (185) were female CHD participants and 66% (362) male. In women, CHD was associated with hypertension (OR = 3.28 (1.81-5.9)), lipid disorders (OR = 2.40 (1.50-3.83)), diabetes mellitus (OR = 2.08 (1.24-3.50)), kidney disease (OR = 2.66 (1.101-6.99)), thyroid disease (OR = 1.81 (1.18-2.79)), gout/high uric acid levels (OR = 2.08 (1.22-3.56)) and osteoporosis (OR = 1.69 (1.01-2.84)). In men, CHD patients were more likely to have hypertension (OR = 2.80 (1.94-4.04)), diabetes mellitus (OR = 1.87 (1.29-2.71)), lipid disorder (OR = 1.82 (1.34-2.47)), and chronic kidney disease (OR = 3.28 (1.81-5.9)). Conclusion Our analysis revealed two sets of chronic conditions associated with CHD. The first set occurred in both women and men, and comprised known risk factors: hypertension, lipid disorders, kidney disease, and diabetes mellitus. The second set appeared unique to women: thyroid disease, osteoporosis, and gout/high uric acid. Identification of shared and unique gender-related associations between CHD and other conditions provides potential to tailor screening, preventive, and therapeutic options.

Abstract(495)
Abstract:
Background The association of systolic blood pressure (SBP) with mortality in heart failure (HF) patients is paradoxical, and the time points of baseline SBP are also different across prior studies. We hypothesized that the levels of SBP at admission and at discharge had different associations with postdischarge events. Methods The study population included patients hospitalized for decompensated HF in the Heart Failure Center of Fuwai Hospital from January 1, 2009 to December 31, 2014. The primary outcome was a composite of cardiovascular (CV) death and heart transplantation. Multivariate Cox proportional-hazards and restricted cubic spline analyses were used to assess the relationships between SBP at different time points and outcomes. Results In total, 2005 patients were included with a median follow-up of 48.4 months. The median age was 59 years, and 69.9% were male. Multivariate Cox analyses showed that compared with SBP P = 0.005; 120?134 mmHg, HR = 0.658, P P = 0.001). Patients whose discharge SBP was higher than 135 mmHg had a similar primary outcome as those with SBP P = 0.867), and the results remained unchanged even after adjusting for admission SBP (HR = 1.235, P = 0.291). The results of restricted cubic spline analysis indicated similar associations. Conclusions Lower but not higher SBP at admission is associated with more CV deaths/heart transplantations (a reverse J-shaped curve). In contrast, there is a U-shaped association between discharge SBP and CV mortality/heart transplantation.

Abstract:
Background Anemia is a common comorbidity of patients with Takayasu arteritis (TA). This study evaluated the prevalence, clinical characteristics, and treatment in Chinese TA patients with anemia. Methods This retrospective study included 533 consecutive patients hospitalized for TA from January 2009 to April 2018. Anemia was diagnosed on the basis of hemoglobin level, according to World Health Organization criteria. Results A total of 194 patients (36.4%) were diagnosed with anemia. Most had mild anemia (177, 91.2%). Female patients were predominant (92.8% of anemic patients). Normocytic anemia (62.9%) was the most common pattern. Anemic patients were more likely than non-anemic patients to have dizziness (29.4% vs. 21.2%), low body mass index (22.0 ± 3.6 vs. 22.9 ± 3.4 kg/m2), and active disease stage (64.9% vs. 50.1%); pulmonary involvement (12.4% vs. 26.8%), pulmonary hypertension (12.9% vs. 20.1%) and pulmonary hypertensive-target drugs (2.8% vs. 11.6%) were less common among anemic than non-anemic patients (all P Conclusions Anemia is a very common concurrent condition in TA, especially in young, female patients. Patients with anemia are more likely to be in the active disease stage. Iron supplementation helps increase hemoglobin.

Abstract:
Objective To investigate the effect of ramipril on progression of nonculprit lesions in patients with ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI). Methods A total of 200 patients (60.1 ± 11.3 years) with STEMI who underwent successful PPCI from January 2010 to December 2013 were enrolled in this study. All patients underwent PPCI as treatment for culprit lesions. Patients were divided into two groups according to the dosage of ramipril used at hospital discharge as follows: high dosage group (2.5–10 mg, q.d.) and low dosage group (1.25–2.5 mg, q.d.). Clinical and angiographic follow-up was performed for 12 months. The primary endpoint was clinically-driven percutaneous coronary intervention (PCI) for nonculprit lesions. The clinical and angiographic features were analyzed. Results Clinical and angiographic follow-up was performed with 87 patients in the high dosage group and 113 patients in the low dosage group. The numbers of patients who underwent additional PCI were six and 20 in the high and low dosage groups, respectively. The rate of having additional PCI performed was lower in the high dosage group than in the low dosage group (6.90% vs. 17.70%, P = 0.03). Conclusions A high dosage of ramipril may prevent progression of nonculprit lesions, which could be the major cause of recurrent PCI in patients with STEMI after PPCI.

Abstract:
Objective To investigate whether ABO blood groups is associated with the severity of coronary artery disease (CAD). Methods Between January 2015 and December 2017, 1425 first diagnosed CAD patients confirmed by selective coronary angiography were recruited into this cross-sectional study, and their baseline characteristics, ABO blood groups, Gensini score were collected. Multiple linear regression analysis was performed to test the association between the severity of CAD and ABO blood groups. Results The Gensini score was significantly higher in the blood group A than in the non-A groups (41.2 ± 32 vs. 38 ± 27; P = 0.026). After adjusting for age, male, smoking, family history of CAD, hypertension, diabetes mellitus and hypercholesterolemia, multivariate linear regression indicated that blood group A was associated with the severity of CAD (β = 3.298, 95% CI: 0.91–6.505, P = 0.044). In diabetes group, A blood type was also associated with increased Gensini score (P = 0.02) after adjusting for age, male, family history of CAD, hypercholesterolemia, smoking and hypertension. Conclusion In this cross-sectional study, the data indicated that blood group A was an independent risk factor of severity of CAD in Chinese population and Chinese patients with type 2 diabetes.

Abstract:
Background Studies evaluating safety of warfarin and direct oral anticoagulants (DOACs) for prevention of stroke in patients with atrial fibrillation (AF) are lacking. Methods & Results All patients (n = 196,521) receiving care at veteran’s affairs with active cancer and AF from 2010–2015 were included. One-year mortality was significantly higher in unadjusted analysis with warfarin (44.9%) compared to dabigatran (25%, P P P P vs. 11.1%, 12.0%, 14.0%) was similar, however risk of hemorrhagic stroke was significantly higher among patients receiving warfarin (1.2%) compared to patients receiving dabigatran (0.5%), rivaroxaban (0.7%) and apixaban (0.8%) respectively, P = 0.04. Conclusions We demonstrated the superior safety profile of DOACs compared to warfarin among patients with underlying cancer and AF. Warfarin was associated with higher mortality, similar ischemic stroke risk but higher risk of hemorrhagic stroke.

Abstract(509)
Abstract:
Background Pulse wave velocity (PWV) is a marker of arterial stiffness, which represents sub-clinical atherosclerosis. Pulsatile stress and high-sensitivity C-reactive protein (hs-CRP) are associated with arteriosclerosis. However, there is no prospective data confirming whether changes in pulsatile stress and inflammatory markers affect the progression of arterial stiffness. The aim of this study was to investigate the relationships over time between the effects of changes in pulsatile stress and hs-CRP, and arterial stiffness progression during a 2-year follow-up. Methods We performed a longitudinal study involving 3978 participants. All participants underwent a physical examination in 2010–2011 and 2012–2013, during which we measured participants’ hs-CRP levels, brachial–ankle pulse wave velocity (baPWV), and pulsatile stress. Results Baseline hs-CRP was correlated with baPWV (r = 0.18, P = 0.000); however the correlation was weaker than that with systolic blood pressure (r = 0.65), pulsatile stress (r = 0.57), and rate-pressure product (r = 0.58). Multiple linear regression analysis demonstrated that changes in pulsatile stress, mean arterial pressure, and low-density lipoprotein-C (LDL-C) were positively correlated with changes in baPWV, with correlation coefficients of 0.27, 0.25, and 0.07, respectively, but not with changes in hs-CRP. Moreover, each 100-aU increase in pulsatile stress, 1 mmHg increase in mean blood pressure, and 1 mmol/L increase in LDL-C was associated with a 3 cm/s, 4.78 cm/s, and 17.37 cm/s increase in baPWV, respectively. Conclusions Pulsatile stress increases are associated with arterial stiffness progression, but that changes in hs-CRP had no effect on arterial stiffness progression. Hs-CRP may simply be a marker of inflammation in arterial stiffness and has no association with arterial stiffness progression.
