- The Role of Diastolic Blood Pressure When Treating Isolated Systolic Hypertension
Mean systolic blood pressure at specific time points for those patients who did or did not experience a cardiovascular CVD event in the placebo and active treatment groups.
Reduction of diastolic blood pressure to less than mmHg does not improve mortality and may lead to adverse cardiovascular events in high risk patient populations. Despite a growing body of evidence supporting the J-curve phenomenon, no major society guidelines on hypertension include a lower threshold target for diastolic blood pressure. Many major society guidelines for hypertension have been updated in the last 5 years.

Blood pressure BP is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries. Blood pressure is usually expressed in terms of the systolic pressure maximum pressure during one heartbeat over diastolic pressure minimum pressure between two heartbeats in the cardiac cycle. It is measured in millimeters of mercury mmHg above the surrounding atmospheric pressure. Blood pressure is one of the vital signs —together with respiratory rate , heart rate , oxygen saturation , and body temperature —that healthcare professionals use in evaluating a patient's health.
Allan S. Brett, MD and Harlan M. N Engl J Med Jul Fifty years ago, diastolic blood pressure BP was thought to be more predictive of adverse cardiovascular CV events than systolic BP, but epidemiologic studies eventually overturned that idea. Now, researchers have explored relations between BP and 8-year CV outcomes myocardial infarction or stroke in more than 1 million adults median age, 53 from northern California's Kaiser Permanente health system. The analysis used weighted averages of each person's BP measurements median, 22 measurements per person during the 8-year observation period. In multivariable analyses, systolic and diastolic BP were each associated independently with increased risk for CV events, but the effect was greater for systolic than for diastolic BP.

What do your blood pressure numbers mean? Understanding your results is key to controlling high blood pressure. Note: A diagnosis of high blood pressure must be confirmed with a medical professional. We can win the battle against heart disease and stroke — but only with your help. Give a gift that saves lives.
Measure your blood pressure regularly to help your health care team diagnose any health problems early. Measuring your blood pressure is the only way to know whether you have high blood pressure. High blood pressure usually has no warning signs or symptoms, and many people do not know they have it.
Уже направляясь к двери, Сьюзан внимательно посмотрела на ТРАНСТЕКСТ. Она все еще не могла свыкнуться с мыслью о шифре, не поддающемся взлому. И взмолилась о том, чтобы они сумели вовремя найти Северную Дакоту. - Поторопись, - крикнул ей вдогонку Стратмор, - и ты еще успеешь к ночи попасть в Смоки-Маунтинс. От неожиданности Сьюзан застыла на месте.
