Initial systolic blood pressure (SBP) > 160 mmHg; elevated initial biomarkers including leukocytes (> 11 K/uL), lactate dehydrogenase (> 192 U/L), interleukin-6 (IL-6) (> 5 pg/mL), troponin-I (0.04–0.09 ng/mL, > 0.09 ng/mL), B-type natriuretic peptide (BNP) (> 100 pg/mL), serum creatinine (> 1.4 mg/dL), aspartate aminotransferase (> 41 U/L); presenting hypokalemia (< 3.5 mEq/L) and hypomagnesemia (< 1.8 mg/dL); age > 60 years; male sex; and history of CVA, CAD, and cigarette smoking were associated with an increased risk of ATE (p < 0.05 for all comparisons). Here, IL6 is linked to familial primary hypomagnesemia.
