AimsHigh-sensitivity troponin T (hs-TnT) and high-sensitivity C reactive protein (hs-CRP) may convey prognostic information in patients with aortic stenosis (AS). This study evaluated if hs-TnT and hs-CRP associate with myocardial mass, and risk of future surgery for AS.MethodsIn total, 336 patients (48% women) with surgery for AS with previous participation in large population surveys were identified. Preoperatively, myocardial mass and the presence of coronary artery disease (CAD) were assessed. Two matched referents were allocated for each case, and hs-TnT and hs-CRP were determined in stored plasma from the baseline survey. Conditional logistic regression analysis was used to estimate the risk (OR (95% CI)) related to one (natural logarithm) SD increase in hs-TnT and hs-CRP. Kaplan-Mayer and Cox regression analyses were used to evaluate time to surgery.ResultsMedian age (IQR) was 59.8 (10.3) years at survey, and median time between survey and surgery was 10.9 (9.3) years. Hs-TnT was independently associated with surgery for AS (1.24 (1.06–1.44)) irrespective of CAD, whereas Hs-CRP was not (1.05 (0.90–1.22)). Elevated hs-TnT levels at survey associated with shorter time to surgery (p<0.001), and with increased myocardial mass (p=0.002). Hs-CRP did not associate with time to surgery or with myocardial mass.ConclusionsHs-TnT—but not hs-CRP—was associated with increased risk of—and shorter time to—future surgery for AS. Hs-TnT associated with myocardial mass at surgery which indicates that hs-TnT could be a potential biomarker for determining intervention.

Abstract Objective High-sensitivity troponin T (hs-TnT) and high-sensitivity C-reactive protein (hs-CRP) may convey prognostic information in patients with aortic stenosis (AS). However, many association studies were cross-sectional, and the presence of myocardial hypertrophy and concomitant coronary artery disease (CAD) were usually not described. This study evaluated if hs-TnT and hs-CRP relate to myocardial mass, and associate with risk of and time to future surgery for AS in patients with and without concomitant CAD. Design In total, 336 patients who underwent surgery due to AS after participation in large population surveys were identified. Median age [interquartile range] was 59.8 [10.3] years at survey and 68.3 [12.7] years at surgery, and 48% were women. The median time between survey and surgery was 10.9 [9.3] years. Preoperatively, myocardial mass and the presence of CAD were assessed. Two matched referents were allocated for each case, and hs-TnT and hs-CRP were determined in stored plasma samples from the baseline survey. Uni- and multivariable conditional logistic regression analyses were used to estimate the risk (odds ratio [95% confidence interval]) related to one (ln) standard deviation increase in hs-TnT and hs-CRP. Time to surgery was evaluated by Kaplan-Mayer analysis and Cox regression. Results Hs-TnT was independently associated with surgery for AS in patients with concomitant CAD (odds ratio [95% confidence interval]) (1.22 [1.02–1.46]) and without concomitant CAD (1.39 [1.05–1.84]). Hs-CRP was not associated with surgery for AS after adjustment for traditional cardiovascular risk factors (1.06 [0.92–1.23]). Patients with high hs-TnT levels had shorter time to surgery compared those with low levels (Figure, p&lt;0.001) whereas hs-CRP did not associate with time to surgery. Hs-TnT levels at survey associated independently with myocardial mass at surgery (p=0.002) but not with CAD and severity of stenosis. Conclusions Hs-TnT – but not hs-CRP – was associated with increased risk for, and shorter time to future surgery for AS. Hs-TnT associated with myocardial mass at surgery which indicates that Hs-TnT may be used as a clinical tool and allow for identification of patients with AS who could benefit from earlier intervention.

Objective: The aim of this study was to determine the independent value of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein to predict onset of cardiopulmonary disease in a large, multi-center systemic sclerosis cohort followed prospectively. Methods: Subjects from the Canadian Scleroderma Research Group registry with data on N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were identified. Outcomes of interest were death, systolic dysfunction (left ventricular ejection fraction < 50% or medications for heart failure), pulmonary arterial hypertension by right heart catheterization, pulmonary hypertension by cardiac echocardiography (systolic pulmonary artery pressures ⩾ 45 mmHg), arrhythmias (pacemaker/implantable cardiac defibrillator or anti-arrhythmic medications), and interstitial lung disease. Multivariate Cox proportional hazard models were generated for each outcome. Results: A total of 675 subjects were included with a mean follow-up of 3.0 ± 1.8 years. Subjects were predominantly women (88.4%) with mean age of 58.2 ± 11.3 years and mean disease duration of 13.7 ± 9.1 years. One hundred and one (101, 15%) subjects died during follow-up, 37 (6.4 %) developed systolic dysfunction, 18 (2.9%) arrhythmias, 34 (5.1%) pulmonary arterial hypertension, 43 (7.3%) pulmonary hypertension, and 48 (12.3%) interstitial lung disease. In multivariate analyses, elevated levels of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were associated with increased risk of death, while elevated levels of N-terminal pro b-type natriuretic peptide and C-reactive protein were associated with increased risk of developing pulmonary hypertension. Conclusion: In systemic sclerosis, N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein have independent predictive value for death and pulmonary hypertension. A larger study would be required to determine the predictive value of these biomarkers for less common systemic sclerosis outcomes.

Abstract Background It has been reported that coronary artery disease (CAD) is characterized by inflammation and non-obstructive CAD (NOCAD) increases the risk of cardiovascular events (CVEs) compared with ones with normal or near-normal coronary arteries (NNCA), even is similar to obstructive CAD (OCAD). We hypothesized that elevated high-sensitivity C-reactive protein (hs-CRP) may be linked to CVEs in those patients with NOCAD. Purpose To investigate the predictive role of hs-CRP in patients with NOCAD. Methods Of 7,746 consecutive patients with angina-like chest pain admissions, 4,662 eligible patients were enrolled who received coronary artery angiography (CAG) and followed up for the CVEs comprising all-cause mortality, myocardial infarction, stroke and late revascularization. According to the results of CAG, the patients were classified as NNCA group (<20% stenosis, n=698, 15.0%), NOCAD group (20–49% stenosis, n=639, 14.3%), and OCAD group (≥50% stenosis, n=3325, 70.7%). They were further subdivided into 3 groups according to baseline hs-CRP levels (<1, 1–3 and >3 mg/L). Proportional hazards models were used to assess the risk of CVEs in all patients enrolled. Results A total of 338 patients (7.3%) experienced CVEs during an average of 13403 person-years follow-up. Patients with NOCAD and OCAD had higher rates of CVEs compared to those with NNCA (p<0.05, respectively). In Cox's models after adjustment of confounders, the risk of CVEs elevated with the increasing degrees of CAD with hazard ratio of 2.01 [95% confidence interval (95% CI): 1.07–3.79, p=0.03] for patients with NOCAD and 2.81 (95% CI: 1.60–4.93, p<0.001) for patients with OCAD compared with the NNCA group. Moreover, elevated hs-CRP levels were associated with the severity of coronary lesions and an elevated increased risk of CVEs in patients with NOCAD and OCAD compared those with NNCA (p<0.05, respectively). Conclusions Patients with NOCAD had indeed worse outcomes and hs-CRP levels were positively in relation to the CVEs in those with NOCAD, which may help to the risk assessment in ones with NOCAD.

Background and Objectives: This study was to characterize the association of cumulative exposure to increased high-sensitivity C-reactive protein (hs-CRP) with chronic kidney diseases (CKD). Methods: We included 35,194 participants with hs-CRP measured at three examinations in 2006, 2008, 2010. Participants were classified into nonexposed group (hs-CRP <3.0 mg/L in all 3 examinations), 1-exposed group (hs-CRP ≥3.0 mg/L in 1 of the 3 examinations), 2-exposed group (hs-CRP ≥3.0 mg/L in 2 of the 3 examinations), and 3-exposed group (hs-CRP ≥3.0 mg/L in 3 examinations). Cox proportional hazards models were used to assess the association of cumulative hs-CRP with incident CKD. CKD includes an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or urinary protein positive. Results: The study showed the risk of CKD as the number of years of exposure to hs-CRP increases. Participants in 3-exposed group had significantly increased CKD risk with hazard ratio (HR) (95% confidence interval, CI) of 1.70 (1.49–1.93), in comparison with 1.47 (1.34–1.62) for participants in the 2-exposed group, and 1.08 (1.00–1.16) for those in the 1-exposed group (p < 0.01); meanwhile, the similar and significant associations were also observed for eGFR <60 mL/min/1.73 m2, proteinuria positive, in participants of the 3-exposed group in comparison with the nonexposed group, with respective HRs (95% CI) of 1.27 (1.01–1.58) and 2.27 (1.87–2.76). Conclusions: Cumulative exposure to hs-CRP was associated with a subsequent increased risk of CKD and was of great value to risk prediction.

Abstract: Central obesity is recognized as a major factor that associated with increased risk for some chronic diseases. Waist to hip ratio described the increase in visceral adipose tissue and subcutaneous fat on waist circumference and hip circumference.C-reactive protein is the detection of cardiovascular disease risk in conventional but not sensitive enough to detect cardiovascular risk so  beused the new method is of high sensitivity C-reactive protein.The research have purpose to know the difference and relationship of waist to hip ratio and high sensitivity c-reactive protein level between obese and non-obese students at Medical Faculty of Sam Ratulangi University Manado. This research was an observational analytic cross-sectional approach. The results of statistical analysis using the Mann-Whitney U test revealed that there were significant differences (p = 0.000 <0.05) both WHR and hs-CRP level in both groups of students are. Conclusion: The results of statistical analysis using the Spearman test showed that there is a positive very weak relationship (r = 0309) and significant (p = 0017 <0.05) between the values ​​of WHR with hs-CRP level in obese and non-obese students at Medical Faculty of Sam Ratulangi University Manado. Key Words: WHR, hs-CRP     Abstrak: Obesitas sentral diakui sebagai factor utama yang dikaitkan dengan peningkatan resiko untuk beberapa penyakit kronis. Waist to hip ratio (WHR) menggambarkan peningkatan jaringan adiposa visceral dan lemak subkutan pada lingkar pinggang dan lingkar pinggul. C-reactive protein (CRP) merupakan deteksi risiko penyakit kardiovaskular tapi secara konvensional tidak cukup sensitif untuk mendeteksi risiko kardiovaskular sehingga digunakan metode baru yaitu high sensitivity C-reactive protein (hsCRP). Penelitian bertujuan untuk mengetahui perbedaan dan hubungan waist to hip ratio (WHR) dengan kadar high sensitivity c-reactive protein (hs-CRP) serum pada mahasiswa obes dan tidak-obes di Fakultas Kedokteran Universitas Sam Ratulangi Manado. Penelitian ini bersifat observasional analitik dengan menggunakan pendekatan cross-sectional. Hasil analisis statistic dengan menggunakan uji Mann-Whitney U menunjukan terdapat perbedaan yang bermakna (p=0.000<0.05) baik WHR maupun kadar hs-CRP serum pada kedua kelompok mahasiswa tersebut. Simpulan: Hasil analisis statistic dengan mengguna-kan uji Spearman menunjukan bahwa terdapat hubungan yang positif sangat lemah (r=0.309) dan bermakna (p=0.017<0.05) antara nilai WHR dengan kadar hs-CRP serum mahasiswa obes dan tidak-obes pada Fakultas Kedokteran Universitas Sam Ratulangi Manado. Kata Kunci: WHR, hs-CRP

Objective The clinical implication of coronary tortuosity is unclear. The present study was conducted to determine the relationships between coronary tortuosity and the high-sensitivity C-reactive protein (hs-CRP) concentration and between coronary tortuosity and cerebrovascular accident in hypertensive patients without coronary artery disease. Methods In total, 236 patients with normal coronary angiography findings were categorized into 3 different groups: control participants (n = 58), who had neither hypertension nor coronary tortuosity; patients with hypertension but no coronary tortuosity (H-NCT group, n = 93); and patients with both hypertension and coronary tortuosity (H-CT group, n = 85). The hs-CRP concentration was measured in every patient, and 168 hypertensive patients were followed up for at least 2 years to check for the development of cerebrovascular accident. Results The hs-CRP concentration was significantly higher in the H-CT group than in the control and H-NCT groups (4.33 ± 3.15 vs. 1.52 ± 1.31 and 2.31 ± 2.09 mg/L, respectively). The incidence of lacunar infarction was higher in the H-CT than H-NCT group during the follow-up. Conclusions Hypertensive patients with coronary tortuosity have a higher serum hs-CRP level concentration and have a higher incidence of lacunar infarction than hypertensive patients without coronary tortuosity.

IntroductionThe aim of this preliminary study is to assess, in a sample of patients with Coronary Heart Disease (CHD), the specific association between depressive symptoms and systemic inflammation.MethodsSixty-One inpatients with CHD, 31 Unstable Angina and 28 Myocardial Infarction, participated in the study. The plasma levels of C Reactive Protein were measured using Dade Behring’s High Sensitivity CRP assay (hs-CRP) at T0, T30 and T90.At the same timings, they were tested by an examiner, unaware of their diagnosis, with a psychometric battery (SCL90-R, HDRS, MADRS, BDI, QlesQ).ResultsThe elevation of hs-CRP occurs during the whole observation period, with maximum significance at T90 (p = 0,031).A multivariate analysis at T0 indicates a statistical correlation between SCL90-R scores and hs-CRP levels (p = 0.02).The SCL90-R is also associated with the risk of further cardiac events (p = 0.013).Also the BDI could be useful as a prognostic factor (p = 0.026).We found a trend towards correlation between CRP values and depressive symptoms, but it never reaches statistical significance for the other scales.ConclusionsThe feelings of loss and the fear of death, related to the environmental and emotional situation of the hospitalization, may prevail in the acute phase of CHDs.Some patients may overcome this reactive depression, while others may exhibit a biological depression, related to the high level of CRP and thus to an increased risk of re-infarction and other coronary events.

BACKGROUND: The incidence of acute myocardial infarction (AMI) is increasing worldwide. Inflammation plays an essential role in the initiation and progression of atherosclerosis and the pathogenesis of acute cardiovascular events. C-reactive protein (CRP) has been shown to have prognostic value in patients with acute coronary syndrome, but the most promising use of CRP has been used for primary use. AIM: This study was aimed to explore the sensitivity of high-sensitivity CRP (hs-CRP) in assessing troponin T in AMI. METHODS: The study design was an observational study to assess the sensitivity and specificity of hsCRP against troponin T in patients with AMI with ST-elevation and without ST-elevation. This research was conducted in Palembang, Indonesia. The study subjects were 56 patients with an acute myocardial infusion that met the inclusion and exclusion criteria. RESULTS: The sensitivity of hs-CRP to troponin-T is 93.7%. The specificity of hs-CRP to troponin T was 37.5%. The positive suspected value is 0.9, the estimated negative value is 0.5, the positive likelihood ratio is 1.49, and the negative likelihood ratio is 0.16. CONCLUSION: hs-CRP is quite sensitive in assessing troponin-T but not specific enough in assessing troponin-T activity.

Abstract Background: Increased concentrations of high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, are associated with increased risk for coronary heart disease. Because of its relationship to inflammation, hs-CRP has considerable biologic variation. This study was carried out to characterize CRP variation and to compare it to another risk factor, total serum cholesterol. Methods: One hundred thirteen individuals were scheduled to have five measurements each of hs-CRP and total cholesterol carried out at quarterly intervals over a 1-year period. Variations of hs-CRP and total cholesterol were characterized, and classification accuracy was described and compared for both. Results: The relative variation was comparable for hs-CRP and total cholesterol. When classified by quartile, 63% of first and second hs-CRP measurements were in agreement; for total cholesterol it was 60%. Ninety percent of hs-CRP measurements were within one quartile of each other. This relationship was not altered by the use of log-transformed hs-CRP data. Conclusion: hs-CRP has a degree of measurement stability that is similar to that of total cholesterol.

Objectives: Adiponectin, a major cytokine from adipose tissue, and high sensitivity C-reactive protein (hs-CRP), well-established markers of inflammation are known to be associated with increased risk of cardiovascular disorders (CVD). Therefore the objective of our study was to evaluate the levels of these parameters and determine their correlation with glycemia to assess the cardiovascular risks in the patients with Type 2 diabetes mellitus.Methods: This study was conducted in the Department of Biochemistry, Santosh Medical College, Ghaziabad, with 25 Type 2 diabetic patients and 25 age and sex-matched controls. Ethical clearance from the institution and informed consent from the patients were taken before the study. Adiponectin was analyzed by enzyme-linked immunoadsorbent assay, and blood sugar and CRP were estimated by the kit based method.Results: Fasting blood sugar (FBS, 158.2±37.2) and hs-CRP (3.97±1.54) were significantly high, adiponectin was significantly low in the patients with diabetes compared to controls (80.52±9.72, 1.27±0.75, and 10.78±1.69, respectively, p<0.05). Adiponectin showed a negative correlation with FBS (r=−0.427) and hs-CRP (r=−0.336), but the correlation was significant only in case of FBS (p<0.05). hs-CRP positively correlated with FBS (r=0.568) and was statistically significant.Conclusion: The results of our study further support the role of adiponectin and hs-CRP as a predictive biomarker of CVD risks in the patients suffering from Type 2 diabetes.
