Sindrom koroner akut (SKA) merupakan salah satu kegawatan kardiovaskular diInstalasi Gawat Darurat (IGD). Tatalaksana SKA yang ada saat ini membutuhkan waktuminimal 3 jam untuk menentukan apakah pasien dirawat atau dipulangkan, hal ini akanberdampak pada kepadatan IGD dan pemborosan biaya perawatan. European Society ofCardiology merekomendasikan algoritma 0/1 jam pada pasien dengan gambaran EKGnon elevasi segmen ST (NEST) dengan menggunakan high sensitive troponin T (hscTnT)dalam menegakkan atau penapisan infark miokard akut non elevasi segmen ST(IMA-NEST). Penelitian ini bertujuan untuk membandingkan nilai diagnostik hs-cTnTjam ke-1 dan jam ke-3 pada terduga SKA non elevasi segmen ST dengan awitan nyeridada kurang dari 6 jam. Desain penelitian potong lintang. Sebanyak 100 subjekpenelitian yang diambil secara konsekutif sampling. Sensitivitas, spesifisitas, nilaiprediksi positif, dan nilai prediksi negatif kadar hs-cTnT 0/1 jam secara berurutanadalah 93,75%, 98,81%, 93,75%, 98,81%, sementara sensitivitas, spesifisitas, nilaiprediksi positif, dan nilai prediksi negatif kadar hs-cTnT 0/3 jam secara berurutanadalah 87,50%, 96,81%, 93,33% 97,65%. Pemeriksaan hs-cTnT 0/1 jam dapatdipergunakan dalam rule in dan rule out terduga IMA-NEST dengan awitan nyeri dadakurang dari 6 jam.

Acute coronary syndrome (ACS) is one of the cardiovascular events in an EmergencyInstallation (ED). The patients management of ACS required at least 3 hours todetermined whether the patient hospitalized or outpatient, these would increased EDscrowded and high cost treatment. The European Society of Cardiology recommended a0/1 hour algorithm in patients with ECG showed non ST segment elevationusing highsensitive troponin T (hs-cTnT) parameter to rule in or rule out non ST segmentelevation myocard infarct (NSTEMI).We aimed to compare diagnostic values of hscTnTat the 1st and 3rd hour in NSTEMI with chest pain onset less than 6 hours. Studydesign was cross sectional. A total of 100 subjects enrolled by consecutive samplingmethod. Sensitivity, specificity, positive predictive value, and negative predictive valueof hs-cTnT 0/1 hours were 93.75%, 98.81%, 93.75%, 98.81%, while sensitivity,specificity, positive predictive value, and the negative predictive value of hs-cTnT 0/3hours were 87.50%, 96.81%, 93.33%, 97.65%. Hs-cTnT 0/1 hour test can be used inrule in and rule out suspect NSTEMI with the chest pain onset less than 6 hours.
