Abstract: Inflammation has a vital role in the pathogenesis of heart failure (HF) and coronary artery disease (CAD). Neutrophil-to-lymphocyte ratio (NLR) is an inflammation marker proposed to have a correlation with ejection fraction (EF). This is a simple examination and can be obtained routinely in clinical practice. This study aimed to evaluate the correlation of NLR with EF in hospitalized patients with CAD. This was an observational and analytical study with a cross-sectional design. Samples were eligible CAD patients from May until August 2019 at Prof Dr. R. D. Kandou Hospital in North Sulawesi. All patients underwent echocardiography for EF calculation, and blood examination for NLR measurement and risk factor screening. The patients were treated according to the guideline. Data were analyzed using the Spearman test in SPSS v26. The results showed that the majority of patients were male (70.2%) with mean age of 60 years old. Hypertension was found in 76.6% and smoking history in 51.1% patients. NLR was shown to have a significant correlation with EF in patients with CAD (p=0.014). In conclusion, NLR has a significant correlation with EF. Moreover, it could be a useful tool for the clinicians to predict heart failure in a specific population.

Abstrak: Peradangan memiliki peran penting dalam patogenesis gagal jantung (HF) dan juga penyakit arteri koroner (CAD). Rasio neutrofil-limfosit (NLR) merupakan penanda inflamasi yang diduga berkorelasi dengan fraksi ejeksi (EF), serta merupakan pemeriksaan sederhana yang dapat diperoleh secara rutin dalam praktik klinis. Penelitian ini bertujuan untuk mengetahui korelasi NLR dengan EF pada pasien rawat inap dengan CAD. Jenis penelitian ialah observasional analitik dengan desain potong lintang. Sampel penelitian ialah pasien CAD yang memenuhi syarat dirawat dari bulan Mei hingga Agustus 2019 di Rumah Sakit Prof Dr. R. D. Kandou, Sulawesi Utara. Pasien diperiksakan dengan ekokardiografi untuk perhitungan EF, dan dilakukan pemeriksaan darah untuk penilaian NLR dan skrining faktor risiko. Semua pasien dirawat sesuai dengan pedoman. Data dianalisis menggunakan uji Spearman dengan SPSS v26. Hasil penelitian mendapatkan mayoritas sampel ialah laki-laki (70,2%) dengan usia rerata 60 tahun. Hipertensi ditemukan pada 76,6% dan riwayat merokok pada 51,1% pasien. NLR terbukti memiliki korelasi bermakna dengan EF pada pasien CAD (p=0,014). Simpulan penelitian ini ialah NLR terbukti memiliki korelasi bermakna dengan EF pada pasien CAD. Selain itu NLR dapat menjadi alat bantu yang berguna bagi klinisi untuk memrediksi gagal jantung pada populasi tertentu.
