چکیده

مقدمه: گایدلاین‌های فعلی توصیه به استفاده از سنجش تروپونین با حساسیت بالا (hs-cTnl) برای مدیریت بیماران با علائم سندروم کرونری حاد (ACS) نموده‌اند. علی‌رغم این موضوع، در اورژانس از آزمایش بر بالین بیمار (POC) به شکل رایجی استفاده می‌شود. این مطالعه به دنبال مقایسه نتایج آزمایش RAMP- cTnI با نتایج تروپونین آزمایشگاهی (hs-cTnl) به‌عنوان استاندارد طلایی است.
روش‌ها: مطالعه حاضر روی 148 بیمار مشکوک به سندروم کرونری حاد مراجعه‌کننده به بیمارستان نمازی شیراز در فاصله زمانی مارس تا جولای 2021 انجام شده است. برای ارزیابی تروپونین (cTnl) از دستگاه ویداس (VIDAS) و رویکرد Enzyme Linked Fluorescent Assay(ELFA) استفاده شد. آزمون POC به کمک دستگاه RAMP انجام گردید که با استفاده از نمونه خون کامل، امکان سنجش سریع cTnl بر بالین بیمار، ظرف 10 دقیقه را فراهم می‌کند.
یافته‌ها: در 35 نفر از 148 بیمار hs - cTnI مثبت شد. حساسیت، ویژگی، ارزش اخباری مثبت و منفی RAMP- cTnI در مقایسه با تست حساسیت بالا با فاصله اطمینان 95% به ترتیب 42/91  (% 63/93 - 84/85)، 69/94 ( % 95/97 - 55/87)، 21/84 (% 56/93 – 82/77) و 27/97 (% 56/99 – 82/87) بود.
نتیجه‌گیری: در این مطالعه مشخص شد روش کمی جدید RAMP- cTnI از منظر دقت تشخیص انفارکتوس حاد میوکارد دارای ارزش آماری قابل قبول با hs - cTnI است، درنتیجه RAMP- cTnI برای شناسایی انفارکتوس حاد میوکارد در محیط بخش اورژانس مناسب است.

چکیده [English]

Introduction: Current guidelines recommend using high-sensitivity troponin (hs-cTnl) assays to manage patients with acute coronary syndrome (ACS) symptoms. Despite this, bedside testing (POC) is commonly used in the emergency room, as it reduces the patient's response time and hospital stay. This study seeks to compare the results of the RAMP- cTnI test with the results of laboratory troponin (hs-cTnl) as the gold standard.
Methods: The present study was performed on 148 patients with suspected acute coronary syndrome referred to Shiraz Namazi Hospital between March and July 2021. Blood samples were taken immediately from patients referred to the emergency department for POC and high-sensitivity troponin test (as gold standard). Enzyme-Linked Fluorescent Assay (ELFA) was used to evaluate troponin (cTnl). The POC test was performed using a RAMP device, which allows the rapid measurement of cTnl in the patient's bedside within 10 minutes using a whole blood sample.
Results: Of the 148 patients, 35 were hs-cTnI positive. Sensitivity, specificity, the positive and negative predictive values of RAMP- cTnI compared to high sensitivity test with 95% confidence interval were 91.42 (93.63-85.84), 94.69% (97.95%-87.55), 84.21% (93.56-77.82) and 97.27% (99.56-87.82), respectively.
Conclusion: The study showed that the quantitatively new RAMP- cTnI method was statistically acceptable with hs - cTnI regarding the accuracy of acute myocardial infarction. RAMP- cTnI was found to be suitable for detecting acute myocardial infarction in the emergency department.
