What is the positive coronary artery disease risk-factor threshold for prediabetes?
fasting plasma glucose higher than 150mg/dL but lower than 170mg/dL
fasting plasma glucose higher than 100mg/dL but lower than 126mg/dL
fasting plasma glucose higher than 100mg/dL but lower than 120mg/dL
fasting plasma glucose higher than 140mg/dL but lower than 160mg/dL
The correct answer is: fasting plasma glucose higher than 100mg/dL but lower than 126mg/dL
The threshold for positive coronary artery disease risk associated with prediabetes is determined by specific measurements of fasting plasma glucose. A fasting plasma glucose level that exceeds 100 mg/dL but is less than 126 mg/dL is indicative of prediabetes, which is a crucial metabolic state that can significantly increase the risk for both cardiovascular disease and the development of type 2 diabetes. In terms of coronary artery disease, this threshold is particularly relevant because prediabetes indicates impaired glucose metabolism, which is often accompanied by other metabolic derangements. These can contribute to atherosclerosis and the overall risk of coronary artery disease. Recognizing this threshold helps healthcare providers identify individuals at higher risk, enabling early intervention strategies that may include lifestyle modifications such as diet and exercise to mitigate these risks. The other options present fasting plasma glucose levels that either fall below the recognized threshold for prediabetes or that exceed levels typically associated with other significant metabolic disorders, thus not aligning with the established guidelines for identifying prediabetes related to coronary artery disease risk factors.
