Wasada Heart Clinic, located in Kamimunakata Minami, Oita City, Oita Prefecture, is an internal medicine clinic specializing in cardiovascular diseases, vascular conditions, and lifestyle-related diseases. The clinic treats a wide range of conditions including angina, arrhythmia, heart failure, and arteriosclerosis, as well as diabetes, hypertension, and dyslipidemia, while also providing general internal medicine services for colds, asthma, and hay fever.
