High blood pressure increases the workload on the arteries and heart. If untreated, it could damage the blood vessels of the heart, brain, kidney and might result in stroke, heart failure or kidney failure. Hypertension increases the risk of heart attacks. Therefore, anti-hypertensives such as Aztel 3D 25 mg/12.5 mg Tablet 15's are used to lower the blood pressure to normal; this reduces the risk of developing these disorders.
