Heart patients are set to benefit from nanotechnology as King Abdulaziz University Hospital has used this technology for clearing clogged and clogging arteries with the help of lasers. The hospital used the technology for removing clots in the lower extremities of a patient. Nanotechnology coupled with laser machines has also helped in reducing the side effects attributed with laser. In the case of laser at times remnants are left behind which tend to get hardened over a period of time. Patients suffering from arterial conditions which are caused due to diabetes, smoking or other conditions are subjected to this surgical procedure. Damaged arteries in extreme cases can lead to gangrene or debilitating conditions and nanotechnology has been found out to be effective in clearing clogged arteries and minimize the side effects of laser therapy.
