Kekambuhan gastritis terjadi pada individu yang memiliki kebiasaan makan tidak teratur. Berbagai faktor pemicu seperti makanan yang terkontaminasi bakteri, pola makan tidak teratur, penggunaan obat NSAID, konsumsi alkohol, merokok, stres, uremia, infeksi sistemik, trauma mekanik, dan kortikosteroid yang dapat menghambat sintesis prostaglandin sehingga sekresi HCl meningkat, menimbulkan iritasi pada lambung. Penelitian ini merupakan penelitian kuantitatif dengan desain cross-sectional yang bertujuan untuk mengetahui hubungan antara berbagai faktor risiko dengan kejadian kekambuhan gastritis di Puskesmas Putri Ayu, Kota Jambi. Jumlah populasi dalam penelitian ini sebanyak 729 orang, dengan sampel 98 responden diperoleh melalui accidental sampling. Instrumen adalah kuesioner pola makan, kuesioner DASS-42 dan kuesioner kekambuhan gastritis. Analisa bivariat menggunakan uji Kendall’s Tau-b. Hasil menunjukkan adanya hubungan pola makan (p value = 0,008) ; tingkat stres (p value = 0,044) dengan kekambuhan gastritis. Diharapkan peneliti selanjutnya melakukan penelitian serupa dengan menambah faktor lain yang berhubungan dengan kekambuhan gastritis.

Heart attacks are caused by a blockage that keeps blood from flowing to the heart and to the brain, resulting in further complications such as failure of the heart muscle to get oxygen supply which results in a person's death. Therefore, patients with heart disease require Percutaneous Coronary Intervention to deal with their treatment. PCI is also known as cardiac angioplasty or percutaneous coronary intervention.
