One method for early detection of coronary stenosis that is Diagnostic Coronary Angiography (DCA). Diagnostic Coronary Angiography is a minimally invasive procedure using a diagnostic catheter and guide wire with the help of contrast. Catheterization in clients with complaints of chest pain are not all found stenosis (narrowing) of coronary arteries significantly; even some clients show the results of DCA without stenosis. Total client sampled 159 people, who do DCA catheterization with stenosis ≥ 70% (coronary artery disease) in March 2015 to the month of March 2017 at Universitas Airlangga Hospital (RS Unair) Surabaya, East Java, Indonesia. The findings were then each analyzed risk factors contained in the client retrospectively. The results were obtained by using stepwise logistic regression. The patients who met the criteria, 25 (15.72%) had atypical chest pain, and 134 (84.27%) had typical chest pain. Significant predictors of coronary artery disease (CAD) ≥ 70%, by correlating risk factors with the type of chest pain (atypical chest pain and typical chest pain), included body mass index (BMI) and history of diabetes mellitus (DM) (all p <0.05). Patients of CAD with excess BMI will have a typical chest pain risk of 1.16 probably compared with patients with lower BMI. Patients of CAD with thinner BMI are atypical chest pain. Patients with a history of DM will have atypical chest pain of 0.32 probably compared to patients who have no history of DM. Patients with CAD who did not have a history of DM are at risk of having typical chest pain. The variation in chest pain can be explained by both variables of 9.6%. Accurate prediction of chest pain to the incidence of stenosis ≥ 70% through BMI and history of diabetes mellitus of 84.3%. Body mass index (BMI) and history of diabetes mellitus have a significant correlation to the incidence of chest pain in client with a degree of stenosis ≥ 70%.
