Abstract

Abstrak Latar belakang: Studi sebelumnya menyimpulkan bahwa MVG merupakan parameter yang berhubungan perbaikan gejala pasca KMTP. Tujuan: Evaluasi hubungan MVG terhadap perubahan kapasitas fungsional pasca KMTP. Metode: Studi quasi experimental dilakukan terhadap 78 subjek. Pemeriksaan ekokardiografi dan treadmill Bruce termodifikasi dilakukan 1-2 hari sebelum dan 1-2 minggu setelah KMTP. Data sebelum dan setelah KMTP dianalisis untuk mencari hubungan variabel terhadap perbaikan kapasitas fungsional pasca KMTP. Hasil: Rerata usia adalah 42 tahun, mayoritas perempuan, dan rerata IMT 22,27 kg/m2. Sebelum KMTP, 53% memiliki irama sinus dengan mayoritas memiliki fungsi ventrikel kiri yang baik dan ventrikal kanan yang baik. Sebesar 97% pasien datang dengan kelas NYHA II sebelum KMTP dan mengalami perbaikan signifikan kapasitas fungsional berupa perbaikan median lama latihan (241 ke 603 detik, p < 0,001) dan perbaikan median nilai VO2max estimasi (18,8 ke 32,8 mlO2/kg/menit, p<0,001). Dari uji korelasi, didapatkan variabel usia (r -0,23, adjusted R2=4,1%), pre-MVG (r 0,23, adjusted R2=4,2%), ∆ MVG (r 0,31, adjusted R2= 9,0%), dan pre-TR Vmax (r 0,3, adjusted R2=1,3%) berkorelasi terhadap perubahan kapasitas fungsional. Penurunan MVG > 50 % pasca KMTP (OR 2,89, p = 0,038) dan TR Vmax sebelum KMTP > 3,4 m/s (OR 3,42, p = 0,023) menjadi prediktor perbaikan kapasitas fungsional segera pasca KMTP. Kesimpulan: Penurunan MVG lebih dari 50% pasca KMTP berhubungan dengan perbaikan kapasitas fungsional segera pasca KMTP. Kata Kunci: fungsional, KMTP, lama latihan, MVG, stenosis mitral

Abstract

Abstract Background: Chronic coronary syndrome (CCS) is a leading cause of global morbidity and mortality, closely associated with central obesity. The waist-to-height ratio (WHtR) is a sensitive anthropometric indicator for detecting visceral fat distribution and cardiometabolic risk. Meanwhile, functional capacity can be assessed through the 6-minute walk test (6MWT), reflecting patients' ability to perform daily activities. However, few studies have examined the relationship between WHtR and 6MWT, particularly in CCS Objective: To determine the correlation between WHtR and 6MWT results in CCS patients at Hj. Bunda Halimah Hospital, Batam City. Methods: This pilot study with cross-sectional design involved 20 selected patients with consecutive sampling. All patients were given optimal CCS treatment and were chronic patients of cardiac outpatient clinic. Data were collected through anthropometric measurements (waist circumference and height) and 6MWT following standard protocol. Pearson’s correlation test was used to analyze the relationship between WHtR and 6MWT results. Results: Most respondents had central obesity with WHtR ≥ 0.5 (55%). The mean 6MWT distance was 448.10 m in the control group and 429.40 m in the intervention group (p<0.001). Pearson’s test revealed a significant negative correlation between WHtR and 6MWT (r = -0.719; p < 0.001). There was a significant negative relationship between WHtR and 6MWT results in CCS patient. Discussion and Conclusion: This study shows that a higher WHtR results in a shorter 6MWT distance, or lower functional capacity, in patients with CCS who have received optimal treatment. This suggests that a high WHtR indicates the presence of residual risk factors such as inflammation and ongoing oxidative stress. WHtR is not only a simple indicator for predicting functional capacity and cardiometabolic risk in this population, but also serves as a target for cardiac rehabilitation to improve the functional capacity. Keywords: Coronary artery disease; WHtR; 6-Minute Walk Test; functional capacity; central obesity.
