摘要
目前尚不清楚心肌肌钙蛋白I水平升高在急性下肢缺血患者中的发生率、原因及其临床意义。本研究纳入46例急性下肢缺血的患者(男性20例,43%;平均年龄72±10岁,极差42～92)。对所有患者均连续测定肌酸激酶(CK)、CK同工酶MB(CK-MB)以及肌钙蛋白I水平。对每例患者的峰值水平进行评价。24例患者(52%)在住院期间出现肌钙蛋白I峰值水平升高(>0.2μg/L)。
The presence, cause, and clinical significance of elevated cardiac troponin I in patients with acute lower limb ischemia is yet unknown. Forty-six patients(20 men [43% ]; mean age 72± 10 years, range 42 to 92) with acute lower limb ischemia were enrolled in this study. Serial creatine kinase(CK), CK isoenzyme MB(CK- MB), and troponin I measurements were obtained in all consecutive patients. Peak levels were evaluated for each patient. Twenty-four patients(52% ) had elevated peak troponin I levels(>0.2 ng...
