Hubungan Nilai Fraksi Ejeksi dengan Kelas NYHA pada Pasien Gagal Jantung di Poli Jantung RSUD Dr. Soegiri Lamongan

Latar Belakang: Gagal jantung sering kali dinilai menggunakan klasifikasi berdasarkan nilai fraksi ejeksi dan kelas NYHA. Keselarasan antara kedua klasifikasi tersebut masih tidak konsisten pada beberapa penelitian sebelumnya. Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan nilai fraksi ejeksi dan kelas NYHA pada pasien gagal jantung di poli jantung RSUD dr. Soegiri Lamongan. Metode: Penelitian ini merupakan penelitian analitik observasional dengan pendekatan cross sectional. Populasi penelitian ini adalah pasien rawat jalan di poli jantung RSUD dr. Soegiri Lamongan yang terdiagnosis gagal jantung. Sampel penelitian berjumlah 45 sampel yang diambil menggunakan teknik purposive sampling. Data nilai fraksi ejeksi diambil dari hasil pemeriksaan ekokardiografi, sedangkan kelas NYHA diambil dari wawancara berdasarkan kriteria klasifikasi NYHA. Uji statistik pada analisis bivariat menggunakan uji korelasi Spearman. Hasil: Dari analisis univariat, didapatkan bahwa sebagian besar sampel memiliki nilai fraksi ejeksi > 50% sebanyak 18 responden (40%) dan berada pada kelas NYHA II sebanyak 22 responden (48,9%). Uji korelasi spearman didapatkan nilai p = 0,002 dengan nilai r =  0,448, yang berarti terdapat hubungan yang signifikan secara statistik dengan korelasi negatif antara nilai fraksi ejeksi dan kelas NYHA pada pasien gagal jantung di poli jantung RSUD dr. Soegiri Lamongan. Kesimpulan: Dari penelitian ini, dapat disimpulkan bahwa terdapat hubungan yang signifikan antara nilai fraksi ejeksi dan kelas NYHA pada pasien gagal jantung di poli jantung RSUD dr. Soegiri Lamongan.

Background: Heart failure was often assessed using the classification of ejection fraction values and NYHA class. The alignment between the two classifications was still inconsistent in some previous studies. Objective: This study aimed to determine the relationship between ejection fraction value and NYHA class in heart failure patients at the cardiac clinic of RSUD dr. Soegiri Lamongan. Methods: This study was an observational analytic study with a cross sectional approach. The population of this study was outpatients at the heart clinic of RSUD dr. Soegiri Lamongan who were diagnosed with heart failure. The study sample included 45 samples taken using purposive sampling technique. Ejection fraction value data were taken from the results of echocardiographic examination, while NYHA class was taken from interviews based on NYHA classification criteria. Statistical tests on bivariate analysis used the Spearman correlation test. Results: From the univariate analysis, it was found that most respondents had ejection fraction values > 50% as many as 18 respondents (40%) and were in NYHA class II as many as 22 respondents (48.9%). The Spearman correlation test obtained a p value of 0.002 and an r value of  0.448, which means that there is a statistically significant relationship with a negative correlation between the value of ejection fraction and NYHA class in heart failure patients in the cardiac clinic of RSUD dr. Soegiri Lamongan. Conclusion: From this study, it could be concluded that there was a significant relationship between the value of ejection fraction and NYHA class in heart failure.
