Korelasi Hasil Uji Jalan Enam Menit dengan Uji Latih Treadmill dalam Menilai Pasien Paska Bedah Pintas Arteri Koroner yang Mengikuti Rehabilitasi Jantung Fase II = Correlation of Six-Minute Walk Test Results with Treadmill Exercise Test in Assessing Post-Coronary Artery Bypass Surgery Patients Undergoing Phase II Cardiac Rehabilitation.

Objektif: Penelitian ini bertujuan untuk menganalisis korelasi antara jarak tempuh Uji Jalan 6 Menit (UJ6M) dan kapasitas fungsional uji treadmill pada pasien pasca operasi Bedah Pintas Arteri Koroner (BPAK) dalam program rehabilitasi jantung. Metode: Studi dilakukan selama delapan minggu program rehabilitasi jantung dengan mengukur kapasitas fungsional menggunakan UJ6M dan uji treadmill. Pengukuran dilakukan pada pasien pasca BPAK di Instalasi Pelayanan Kardioserebrovaskular Terpadu RSUPN Cipto Mangunkusumo Jakarta. Hasil: 15 pasien BPAK didominasi oleh laki-laki (73,3%) dengan rerata usia 59 tahun, mayoritas berpendidikan SMA (46,7%), memiliki status gizi overweight (46,7%), dan komorbid utama berupa hipertensi (80,0%), dislipidemia (66,7%), serta diabetes melitus (53,3%), dimana terjadi peningkatan jarak dari 307,8±35,7 meter menjadi 498,5±140,7 meter setelah rehabilitasi jantung fase II. Estimasi kapasitas fungsional berupa ambilan oksigen maksimal dari pasien BPAK yang menjalani rehabilitasi jantung fase II dengan menggunakan uji latih enam menit adalah 18,9+4,2 ml/kg/menit. Estimasi ambilan oksigen maksimal pada uji latih treadmill adalah 21,4 (15,1 -35,8) ml/kg/menit. Terdapat korelasi sedang yang signifikan (r =0,689, p < 0,05) antara hasil uji jalan enam menit dengan uji latih treadmill pada pasien pasca BPAK yang menjalani program rehabilitasi jantung fase II. Kesimpulan: UJ6M terbukti sebagai alat pengukuran yang valid dan praktis untuk menilai kapasitas fungsional pada pasien pasca BPAK, terutama di fasilitas kesehatan dengan keterbatasan akses treadmill. Uji jalan enam menit dapat menjadi dasar peresepan latihan untuk menilai kapasitas fungsional. Rehabilitasi jantung terstruktur dengan program latihan yang disesuaikan secara individual berkontribusi signifikan terhadap pemulihan pasien.

Objective: This study aims to analyze the correlation between the 6-Minute Walk Test (6MWT) distance and the functional capacity of the treadmill test in post-Coronary Artery Bypass Graft (CABG) patients in a cardiac rehabilitation program. Method: The study was conducted during an eight-week cardiac rehabilitation program by measuring functional capacity using the 6MWT and treadmill test. Measurements were taken on CABG patients at the Instalasi Pelayanan Kardioserebrovaskular Terpadu RSUPN Cipto Mangunkusumo Jakarta. Results: The 15 CABG patients were predominantly male (73.3%) with an average age of 59 years, the majority had a high school education (46.7%), had overweight nutritional status (46.7%), and major comorbidities were hypertension (80.0%), dyslipidemia (66.7%), and diabetes mellitus (53.3%), where there was an increase in distance from 307.8±35.7 meters to 498.5±140.7 meters after phase II cardiac rehabilitation. The functional capacity estimation in the form of maximum oxygen uptake of CABG patients undergoing phase II cardiac rehabilitation using a six-minute exercise test was 18.9+4.2 ml/kg/minute. The maximum oxygen uptake estimation in the treadmill exercise test was 21.4 (15.1 -35.8) ml/kg/minute. There was a significant moderate correlation (r = 0.689, p < 0.05) between the results of the six-minute walk test and the treadmill exercise test in post-CABG patients undergoing a phase II cardiac rehabilitation program. Conclusion: The UJ6M has been proven to be a valid and practical measurement tool for assessing functional capacity in post-CABG patients, especially in health facilities with limited treadmill access. The six-minute walk test can be the basis for prescribing exercise to assess functional capacity. Structured cardiac rehabilitation with an individually tailored exercise program contributes significantly to patient recovery.
