Application of Binary Logistic Regression Method in Diagnosing Ischemic Stroke Disease at Petala Bumi Hospital, Riau Province

Stroke occurs suddenly when blood flow is obstructed while supplying blood to the brain. Ischemic stroke is a type of stroke that often occurs and is a major cause of disability and even death. The large number of ischemic stroke incidents is the result of ignorance of the risk factors that lead to the emergence of ischemic stroke events. The purpose of this study was to determine the risk factors that significantly influence ischemic stroke and to determine the chances of thrombotic and embolic ischemic stroke by involving several independent variables. Factors that are thought to influence the occurrence of ischemic stroke in this study were age, gender, hypertension status, diabetes mellitus status, hypercholesterolemia status, obesity, triglycerides, body mass indeks, diet, and smoking habits. The method used in this research is binary logistic regression. Parameter significance testing is carried out using simultaneous testing using the Likelihood Ratio Test and Partial testing using the Wald test. The results of the analysis show that age and hypertension status have a significant effect on ischemic stroke with a classification accuracy of 74% the rest is influenced by other factors.This is an open access article under the CC BY-SA license. Keywords: Binary Logistic Regression Ischemic Stroke 1.INTRODUCTION The brain is a vital organ in the human body, the brain will experience a lack of oxygen and experience physical disorders if blood circulation to the brain is disrupted [1]. Blockage of blood vessels in the brain or rupture of blood vessels in the brain can result in impaired blood circulation to the brain [2]. Impaired blood circulation to the brain causes neurological problems that manifest as loss of additional muscle movement, weakness of the swallowing muscles, weakness in speech, visual disturbances, impaired consciousness, and can even lead to death [3]. Stroke is a disease of nervous system dysfunction where there is a lack of oxygen to brain cells that occurs suddenly and quickly, resulting from the cessation of blood supply to the brain [4][5]. In Indonesia, based on the diagnosis of health workers, the prevalence of stroke is estimated at 1,236,825 people or 7.0 per 1,000 population. Meanwhile, based on the diagnosis of health workers, stroke symptoms are estimated at 2,137,941 people or 12.1 per 1,000 population [6]. Broadly speaking, stroke is classified into two types, namely ischemic stroke and hemorrhagic stroke. Ischemic stroke is the most common stroke occurrence with a percentage of 85%, which is caused by blockage of blood vessels with symptoms according to the affected part of the brain that can be completely healed, healed with defects, and even death [7]. Where ischemic stroke is grouped into two, namely thrombotic ischemic stroke is a stroke that occurs due to blood clots in the arteries that supply blood to the brain. While an embolic ischemic stroke is a stroke caused by a blood clot that forms in other organs of the body flowing into the blood vessels so that it blocks blood flow to the brain [8]. In 2018 the Rakerkesda event recorded that stroke in Riau Province almost increased up to 2 times [9]. In 2019, based on the medical record report of Petala Bumi
