Abstract Elevated troponin levels have been observed in a wide spectrum of patients who do not have ischemic heart disease, including nonacute coronary syndrome and cardiovascular and noncardiovascular conditions. The cases of two patients with diabetic ketoacidosis who had elevated troponin levels in the absence of coronary artery disease are presented. This clinical scenario can pose a diagnostic dilemma for the physician. The objective of the present report is to highlight the mechanism of troponin elevation in patients with diabetic ketoacidosis, in addition to the clinical and prognostic significance of this finding.

Abstract Background: The aim of this study was to evaluate factors influencing the 99th percentile for cardiac troponin I (cTnI) when this cutoff value is established on a highly sensitive assay, and to compare the value of this cutoff to that of lower cutoffs in the prognostic assessment of patients with coronary artery disease. Methods: We used the recently refined Access AccuTnI assay (Beckman-Coulter) to assess the distribution of cTnI results in a community population of elderly individuals [PIVUS (Prospective Study of the Vasculature in Uppsala Seniors) study; n = 1005]. The utility of predefined cTnI cutoffs for risk stratification was then evaluated in 952 patients from the FRISC II (FRagmin and Fast Revascularization during InStability in Coronary artery disease) study at 6 months after these patients had suffered acute coronary syndrome. Results: Selection of assay results from a subcohort of PIVUS participants without cardiovascular disease resulted in a decrease of the 99th percentile from 0.044 μg/L to 0.028 μg/L. Men had higher rates of cTnI elevation with respect to the tested thresholds. Whereas the 99th percentile cutoff was not found to be a useful prognostic indicator for 5-year mortality, both the 90th percentile (hazard ratio 3.1; 95% CI 1.9–5.1) and the 75th percentile (hazard ratio 2.8; 95% CI 1.7–4.7) provided useful prognostic information. Sex-specific cutoffs did not improve risk prediction. Conclusions: The 99th percentile of cTnI depends highly on the characteristics of the reference population from which it is determined. This dependence on the reference population may affect the appropriateness of clinical conclusions based on this threshold. However, cTnI cutoffs below the 99th percentile seem to provide better prognostic discrimination in stabilized acute coronary syndrome patients and therefore may be preferable for risk stratification.

Introduction: Coronary Artery Disease (CAD) is thought to be progressive; standard treatment protocols call for instituting a low fat/low cholesterol diet program, exercise, and lipid lowering agents. This results in an approximate 30-40% new event rate in 5 yrs. We evaluated our treatment strategy to reverse CAD with The Corus Score (CS) (Cardiodx, Redwood City, Ca), proven to quantify coronary artery obstructive plaque by the expression of 23 genes. Methods: Based upon using a Lectin-limited diet to prevent/reverse Metabolic Syndrome and CAD, we have enrolled and followed 800 pts (aged 42-89 yrs) with known CAD, defined as previous MI, stent, CABG, or positive stress test/angiogram, positive CS greater than 30, into a physician coached program, which reduces grains, legumes, nightshades, seeded vegetables, Casein A1 milk, (the all lectin containing food groups),and fruits; emphases consumption a liter of olive oil/wk, large amts of green vegetables, and 4 oz amts of proteins, avoiding commercial poultry (Matrix Protocol). All Apo E 4 genotypes avoided animal fats and cheeses. Pts were instructed to take 4,000 mg of high DHA fish oil, 200mg of Grape Seed Extract, and 25 mg of Pycnogenol per day, and consume polyphenol rich coffee and/or teas and 1 oz dark chocolate/day. Diets/supplements were individualized based on results of Advanced Cardiovascular Risk Markers (ACRM), which were sent to two core labs. Yearly assessment of CAD severity was measured by Corus Score (possible range 1-40). Any score above 30 was assessed by Nuclear Stress testing. Results: Pts have been followed for 1.5 to 6 years (mean 4.5 yrs). Only 6/800 pts (0.5%) have received a new stent, all 6 had rising Corus scores: two also had a rising Lp-PLA2, 2 had rising Cardiac Troponin I levels; one pt required CABG: . There have been no MI’s, unstable angina. Corus scores at baseline decreased from 34+/-4 (range 6-36) to 24+/-3, P<0.01. Only 64/800 pts (8%) had a rise in Corus scores/ 736/800 pts’ CS declined or remained stable (92%). Only 6/64 Corus scores had positive Stress tests. Conclusions: Simple Nutrigenomic-based dietary interventions, based upon ACRM's and Corus Scores, represents a quantum leap forward in preventing/modifying Cardiovascular events in known CAD patients.

Introduction: Higher levels of troponins >10 folds of upper normal limits (UNL) are considered as high-risk patients on coronary angiography sufferers having high levels of troponin-I (>10 folds upper limit normal level) had extra three-vessel coronary artery disease involvement. Objectives: To determine the frequency of degree of cardiovascular disease with Troponin-I level >10 folds ULN in NSTEMI patients at tertiary care hospital. Methodology: It is a cross-sectional study comprising of a total 800 patients recruited from the Department of Cardiology, National Institute of Coronary Disease, Karachi Pakistan based on Exclusion/Inclusion criteria. Results: There are 678 male as well as 122 female patients. The mean troponin-I level was 15.00±6.82 ng/ml. Single vessel disease found in 25.25% cases, two vessel diseases were observed in 37.75% cases, and three vessel diseases were observed in 20% cases. 83% were found with extent of CAD findings on angiography. There have been 678 male and also 122 female patients. The mean troponin-I level was 15.00±6.82 ng/ml. Single vessel disease found in 25.25% cases, two vessel diseases were observed in 37.75% cases, and three vessel diseases were observed in 20% cases. 83% were found with extent of CAD findings on angiography. Conclusion: The higher troponin level found significantly associated with extent of CAD and three vessel disease. To understand the cardiovascular troponin condition of the sufferer as soon as feasible is crucial. Keywords: Extent of Coronary Artery Disease, NSTEMI, Troponin-I Level >10 Folds ULN
