why does diastolic pressure decrease with age

The study evaluated the risk of cardiovascular mortality according to combined spontaneous (non-treatment-related) changes in both systolic and diastolic blood pressure (BP). Long-term longitudinal changes in blood pressure may be a more accurate determinant of cardiovascular risk since changes in systolic or diastolic blood pressure over a period of time reflect the evolution of arterial and arteriolar alterations. Two independent French male cohorts were studied: the IPC cohort (Investigations PrГventives et Cliniques) composed of 15,561 men aged 20 to 82 years who had had two visits spaced four to 10 years apart, and the Paris Prospective Study composed of 6,246 men aged 42 to 53 years, examined annually for a period of four years. None of the subjects were taking antihypertensive medication. Annual changes in BP were estimated, and subjects were divided into groups according to the increase, lack of change, or decrease of systolic or diastolic BP. Nine groups were formed by combining the changes of systolic and diastolic BP. Cardiovascular mortality was assessed for a mean period of 13. 5 years for the IPC Study and 17 years for the Paris Prospective Study.

In both cohorts, after adjustment for age and major risk factors, the group with an increase in systolic and a decrease in diastolic BP presented the highest relative risk of cardiovascular mortality compared to the group with no changes in either systolic or diastolic BP (relative risk: 2. 07 [1. 05 to 4. 06] in the IPC Study and 2. 16 [1. 16 to 4. 01] in the Paris Prospective Study). Assessment of spontaneous changes of BP over a long period of time can contribute to the evaluation of cardiovascular risk. Subjects whose systolic BP increased while their diastolic BP decreased had the highest cardiovascular risk independently of absolute values of BP or other risk factors.
High blood pressure, or hypertension, does not always have observable symptoms.

You may have high blood pressure and feel perfectly fine. So itвs important to regularly monitor your blood pressure to ensure you are within normal levels. Your blood pressure reading includes a top number and a bottom number. The top number is your systolic reading. This is the pressure blood exerts against artery walls when the heart contracts or beats. The bottom number is the diastolic reading. This measures the force against your artery walls when the heart is relaxed or between beats. Your blood pressure will fluctuate throughout the day depending on changes in posture, stress, sleep, and exercise. Regardless of fluctuations, your blood pressure on average should remain less than 120/80 mmHg. Here are blood pressure categories as defined by the American Heart Association. Normal blood pressure: Prehypertension: Stage 1 High Blood Pressure: Stage 2 High Blood Pressure: Hypertensive Crisis increases your risk for developing high blood pressure.

If you have prehypertension, this is an ideal time to assess your diet and lifestyle choices and implement changes. To be, only one number needs to be elevated. For example, if your diastolic number (bottom number) is less than 80, which is within normal, but your systolic number (top number) is greater than 140 then this would be classified as high blood pressure. Changing blood pressure as you age A risk factor for high blood pressure is age, and you canвt change that. You will get older. Increased age equals greater likelihood blood pressure levels will increase. This does NOT mean a higher blood pressure is normal or healthy. Regardless of your age, your goal blood pressure reading is less than 120/80 mmHg. 1. Maintain a healthy weight. If you are overweight, lose weight. 2. 3. Reduce salt intake. 4. Do not smoke. 5.
