Cardiovascular diseases become number one cause of death among people. People must be guided based on proper diet. This paper presented current issues on CVDs and proposed He arTy. HearTy is an expert system embedded on Android Operating System for the screening of cardiovascular diseases
or CVDs. It is a rule-based expert system on Android phone for screening the risk as well as the likelihood of having CVDs based on the risk factors present and symptoms felt by the patient. The system covers five types of CVDs which includes Stroke, Coronary Heart Disease, Heart Attack, Heart Failure, and Peripheral Vascular Disease. The system applies Backward Chaining and RETE Algorithm. Backward Chaining is a type of reasoning for the inference engine which starts with a list of goals and RETE Algorithm is a pattern matching algorithm which identifies a rule that satisfy the pattern in order to generate the outputs. Result of the study showed accuracy of 68.75%, 66.59% sensitivity, error rate of 31.5% and 71.565% specificity which led to require further development of the developed software.
