Task: Intent Identification
Input (English): A high serum angiopoietin-like 2 (ANGPTL2) concentration is an independent risk factor for developing diabetes and is associated with insulin resistance and atherosclerosis. In this work, we have examined the impact of serum ANGPTL2 on improving cardiovascular (CV) risk stratification in patients with type 2 diabetes.', 'A prospective, monocentric cohort of consecutive type 2 diabetes patients (the SURDIAGENE cohort; total of 1353 type 2 diabetes patients; 58% men, mean\u2009±\u2009SD age 64\u2009±\u200911\xa0years) was followed for a median of 6.0\xa0years for death as primary endpoint and major adverse CV events (MACE; i.e. CV death, myocardial infarction or stroke) as a secondary endpoint. Patients with end-stage renal disease, defined as a requirement for dialysis or a history of kidney transplantation, were excluded. Patients were grouped into quartiles according to ANGPTL2 concentrations at inclusion: <11.2 (Q1), 11.2-14.7 (Q2), 14.8-19.5 (Q3) or >19.5 (Q4) ng/ml.', 'During follow up, 367 patients (representing 4.5% of the total person-years) died and 290 patients (representing 3.7% of the total person-years) presented with MACE. Both the survival and MACE-free survival rates were significantly different between ANGPTL2 quartiles (logrank 82.12, p\u2009<\u20090.0001 for death; and logrank 65.14, p\u2009<\u20090.0001 for MACE). Patients with ANGPTL2 concentrations higher than 19.5\xa0ng/ml (Q4) had a significantly higher risk of death and MACE than those with ANGPTL2 levels of 19.5\xa0ng/ml or less (Q1-3) (HR for death 2.44 [95% CI 1.98, 3.00], p\u2009<\u20090.0001; HR for MACE 2.43 [95% CI 1.92, 3.06], p\u2009<\u20090.0001) after adjustment for sex, age and established CV risk factors. Using ANGPTL2 concentrations, prediction of the risk of mortality, as assessed by integrated discrimination improvement (IDI), was significantly improved (IDI 0.006\u2009±\u20090.002, p\u2009=\u20090.0002).
