Hi dear, Diastolic hypertension is an undesirable elevation of the lowest of the two blood pressure numbers.The desirable level of diastolic is about 80 mm Hg. Any rise above that number is associated with an increase in adverse events. Trails done says that; Every 10 mm rise in diastolic pressure causes a doubling of incidence of adverse events such as heart attack, stroke, kidney failure and heart failure. When the heart beats it pushes blood out into the very large blood vessels. These vessels are elastic and take up some of the force by expanding. Then while the heart rests between beats the large vessels contract towards their normal size thus continuing to push blood around the body. This pressure in vessel during relaxation is called diastolic bp. As age progresses fat starts to accumulate in arteries and they loses their elasticity hence does not relax properly causing a elevated diastolic pressure. Increased diastolic pressure can not be alone treated with medicines ,severe life style modification is required 45 minute of strenous exercise should be done low salt food must be taken avoid fatty and oily food 30 minutes of brisk walk daily ecosprin 75mg can be taken daily prevents future cardisc risk a serum lipid pfl should be done it will take atleast 3 months to notice any change he is on high dose of ramipril which causes hypokalenia hence he should take potaasium supllements like banana coconut water daily dont use diuretics now first try wat i advised for 3 months tx
