Association between plasma ADAMTS-7 levels and severity of disease in patients with stable obstructive coronary artery disease.

ABSTRACT: The metalloproteinase family of a disintegrin and metalloproteinase with thrombospondin motifs-7 (ADAMTS-7) was reported to be a novel locus associated with human coronary artery disease. This study aimed to investigate plasma ADAMTS-7 levels in stable obstructive CAD patients and elucidate the relationship between plasma ADAMTS-7 levels and the severity of CAD assessed by the Syntax score.This was a single center cross-sectional study performed in 182 CAD patients. ELISA was used to measure plasma ADAMTS-7 levels. All patients were divided into subgroup according to the ADAMTS-7 median in this cohort: high group with ADAMTS-7 ≥0.99 ng/mL and low group with ADAMTS-7 <0.99 ng/mL. Furthermore, all patients were divided into tertiles according to their Syntax scores (low group: Syntax score ≤10.0; moderate group: 10.0 18.0). We followed up the participants continuously until the first major adverse cardiovascular event (MACE) for a mean time of 22.0 months.Plasma ADAMTS-7 levels in the high Syntax score group were significantly higher compared with the low Syntax score group (3.29 [0.08-26.3] ng/mL vs 1.24 [0.15-8.78] ng/mL, P = 0.010). Plasma ADAMTS-7 levels were significantly positively correlated with the Syntax score tertiles (r = 0.157, P = 0.035). Logistic regression analysis indicated that the plasma ADAMTS-7 level was one of the independent predictors for the Syntax score tertiles (B = 1.118, 95% CI: 1.194-7.830, P = 0.020), together with HbA1c (B = 0.946, 95% CI: 1.248-5.312, P = 0.010), uric acid (B = -0.019, 95% CI: 0.974-0.988, P<0.001), and coronary artery calcium score (B = -0.001, 95% CI: 0.998-0.999, P < 0.001). Compared with the low ADAMTS-7 group, the high ADAMTS-7 group had significantly higher Syntax score (17.10±8.42 vs 14.96 ± 8.11, P = 0.047). Kaplan-Meier analysis showed patients in the high plasma ADAMTS-7 group tend to have a lower event-free survival rate than patients in the low plasma ADAMTS-7 group, unfortunately, no difference was detected (86.8% vs 88.0%, log rank = 0.314, P = 0.575).The plasma ADAMTS-7 level was positively correlated with the Syntax score significantly. The elevated plasma ADAMTS-7 level may be involved in the severity of disease in patients with stable coronary artery disease.

Project description:BackgroundThe relationship between galectin-3 (Gal-3) and coronary artery disease (CAD) has not been fully elucidated.AimThis study aimed to determine the relationship between the presence and severity of CAD and serum Gal-3 levels.Patients and methodsThree-hundred thirty-one consecutive CAD patients were enrolled as the study group. An additional 62 patients without CAD were enrolled as the control group. Serum Gal-3 levels were separately compared between the non-CAD and CAD groups, among the stable CAD and Acute coronary syndrome (ACS) groups, and between CAD patients with low and high SYNTAX scores (SSs). The 1-year cumulative rate of major adverse cardiac events (MACEs) was also compared among ACS patients by Gal-3 levels.ResultsSerum Gal-3 was significantly higher in the CAD group than in the non-CAD group 3.89 (0.16-63.67) vs. 2.07 (0.23-9.38) ng/ml, P < 0.001. Furthermore, serum Gal-3 was significantly higher in the non-ST-segment elevation ACS (NSTE-ACS) group than that in the stable CAD group, 4.72 (1.0-16.14) vs. 2.23 (0.65-23.8) ng/ml, P = 0.04 and higher in the ST-segment elevation myocardial infarction (STEMI) group than that in the stable CAD group 7.87 (0.59-63.67) vs. 2.23 (0.65-23.8) ng/ml, P < 0.001. Serum Gal-3 level was an independent predictor of ACS compared with stable CAD group (OR = 1.131, 95% CI: 1.051-1.217, P = 0.001) as well as high SS (OR = 1.030, 95% CI: 1.021-1.047, P = 0.038) after adjust other confounding risk factors. Acute coronary syndrome patients with Gal-3 levels above the median (gal-3 = 4.78 ng/ml) showed a higher cumulative MACE rate than those with Gal-3 levels below the median. After adjusting other confounding risk factors, Gal-3 remained an independent risk factor for the cumulative rate of MACEs in ACS patients (6% higher rate of MACEs incidence per 1 ng/ml increment of Gal-3).ConclusionGalectin-3 correlated with the presence of CAD as well as coronary stability and complexity. Galectin-3 may be valuable in predicting mid-term prognosis in ACS patients.

Project description:ImportancePhysiological stenosis assessment is recommended to guide percutaneous coronary intervention (PCI) in patients with stable angina.ObjectiveTo determine the association between all commonly used indices of physiological stenosis severity and angina-limited exercise time in patients with stable angina.Design, setting, and participantsThis cohort study included data (without follow-up) collected over 1 year from 2 cardiac hospitals. Selected patients with stable angina and physiologically severe single-vessel coronary artery disease presenting for clinically driven elective PCI were included.ExposuresFractional flow reserve (FFR), instantaneous wave-free ratio (iFR), hyperemic stenosis resistance (HSR), and coronary flow reserve (CFR) were measured invasively. Immediately after this, patients maximally exercised on a catheter-table-mounted supine ergometer until they developed rate-limiting angina. Subsequent PCI was performed in most patients, followed by repeat maximal supine exercise testing.Main outcomes and measuresAssociations between FFR, iFR, HSR, CFR, and angina-limited exercise time were assessed using linear regression and Pearson correlation coefficients. Additionally, the associations between the post-PCI increment in exercise time and baseline FFR, iFR, HSR, and CFR were assessed.ResultsTwenty-three patients (21 [91.3%] of whom were male; mean [SD] age, 60.6 [8.1] years) completed the pre-PCI component of the study protocol. Mean (SD) stenosis diameter was 74.6% (10.4%). Median (interquartile range [IQR]) values were 0.54 (0.44-0.72) for FFR, 0.53 (0.38-0.83) for iFR, 1.67 (0.84-3.16) for HSR, and 1.35 (1.11-1.63) for CFR. Mean (SD) angina-limited exercise time was 144 (77) seconds. Anatomical stenosis characteristics were not significantly associated with angina-limited exercise time. Conversely, FFR (R2 = 0.27; P = .01), iFR (R2 = 0.46; P < .001), HSR (R2 = 0.39; P < .01), and CFR (R2 = 0.16; P < .05) were all associated with angina-limited exercise time. Twenty-one patients (19 [90.5%] of whom were male; mean [SD] age, 60.1 [8.2] years) competed the full protocol of PCI, post-PCI physiological assessment, and post-PCI maximal exercise. After PCI, the median (IQR) FFR rose to 0.91 (0.85-0.96), median (IQR) iFR to 0.98 (0.94-0.99), and median (IQR) CFR to 2.73 (2.50-3.12), while the median (IQR) HSR fell to 0.16 (0.06-0.37) (P < .001 for all). The post-PCI increment in exercise time was most significantly associated with baseline iFR (R2 = 0.26; P = .02).Conclusions and relevanceIn a selected group of patients with severe, single-vessel stable angina, FFR, iFR, HSR, and CFR were all modestly correlated with angina-limited exercise time to varying degrees. Notwithstanding the limited sample size, no clear association was demonstrated between anatomical stenosis severity and angina-limited exercise time.
