Heart is a pumping organ, it pumps blood in the arteries which is circulated throughout the various parts of body. The blood pressure is the force with which blood moves through arteries (the vessels which carry blood from heart to the rest of body). When heart muscle pumps, the force of the blood against artery walls it is called the systolic blood pressure. When heart relaxes between beats, the force of the blood decreases and blood pressure drops, this is called the diastolic blood pressure. When blood pressure is higher than normal value, it is called hypertension (High blood pressure). The high blood pressure has many damaging effects on vital parts of body. There are many reasons for the hypertension and in most of cases the exact diagnosis remains challenge. With the invention of new techniques, it would be possible to diagnose specific cause of blood pressure and it would be possible to develop selective therapies with fewer adverse effects, resulting in effective blood pressure reduction.
