TNNI3 and Hypertension: Univariable analyses revealed that patients who were older (OR = 1.07, 95% CI: 1.01–1.14, P = 0.0342), with hypertension (OR = 5.69, 95% CI: 1.32–24.54, P = 0.0198), prolonged prothrombin time (PT) on admission (OR = 2.1, 95% CI: 1.14–3.88, P = 0.0176), and elevated high sensitivity cardiac troponin I (hs‐TNI) on admission (OR = 8.89, 95% CI, 1.78–44.47) were associated with an increased risk of in‐hospital mortality, whereas elevated platelet count (≥125 × 109/L) (OR = 0.14, 95% CI: 0.03–0.66, P = 0.0123) was associated with a decreased risk.
