Located in Hassamu, Nishi Ward, Sapporo, "Oguma Cardiology and Rehabilitation Clinic" is a medical institution specializing in cardiology. The clinic focuses on treating cardiovascular diseases as well as patient health management and rehabilitation. Notably, it is one of the few facilities in Sapporo equipped with the InBody770 body composition analyzer, which precisely measures body water content and extracellular water ratio. This device is effective for fluid volume management in heart failure patients and for assessing muscle mass and nutritional status during rehabilitation, contributing to disease management and treatment outcome evaluation. Additionally, the clinic offers self-pay vitamin C injections and vitamin B1 injections (commonly known as garlic injections) for those seeking fatigue recovery and immune system enhancement. Vitamin C injections are expected to prevent skin aging and improve pigmentation, while vitamin B1 injections are a highly effective treatment that promotes the elimination of accumulated fatigue substances from the body. With English language support, credit card and electronic payment options, on-site parking, and barrier-free design, the clinic provides an accessible environment for diverse patient populations.
