HOMA-IR (Homeostatic Model Assessment of Insulin Resistance): Explanation and Clinical Context HOMA-IR is a validated index used to estimate insulin resistance based on fasting plasma glucose and insulin levels. The formula is: HOMA-IR = (Fasting Glucose [mg/dL] × Fasting Insulin [µU/mL]) / 405. Higher HOMA-IR values indicate greater insulin resistance. It is commonly used in metabolic and cardiometabolic research an
hs-CRP Tertile Risk Category: Explanation and Clinical Context The hs-CRP (high-sensitivity C-reactive protein) tertile risk categorization stratifies patients into low, intermediate, or high risk of future cardiovascular events based on their hs-CRP levels. According to Ridker et al. (Circulation, 2000), the 1st tertile (<1.0 mg/L) represents low risk, the 2nd tertile (1.0–3.0 mg/L) represents intermediate risk, and
Hypertriglyceridemic Waist (HTGW) Index: Explanation and Clinical Context The HTGW Index is a simple clinical tool combining waist circumference and fasting triglyceride levels to identify individuals at increased cardiometabolic risk. It was first described by Lemieux et al. in 2007 as a marker for visceral obesity and associated metabolic abnormalities, such as insulin resistance, atherogenic dyslipidemia, and incr
