Reducing the systolic blood pressure of an elderly adult to down below 120 mmHg decreases the risk of heart failure, but raises the chance of changes in the kidneys.
More than half of people aged 60 and over in the United States have elevated blood pressure or hypertension, so it can be important to keep one's blood pressure at safe levels.
For people over 65, the American College of Cardiology and American Heart Association (ACC / AHA) recommendations prescribe a systolic blood pressure no higher than 130 milligrams of mercury (mmHg).
By the time many people hit the age of 85, though, they've accumulated health issues. The U.S. Department of Commerce predicts that 10 percent of U.S. people will be 85 or older by 2050. The analysis of blood pressure protocols for certain people has already been undertaken by a team of researchers.
The results of the study come from a 1,167 participants randomized experiment.
The researchers obtained information from the SPRINT (Systolic Blood Pressure Control Trial). They included statistics from people who had suffered strokes, heart problems, organ function changes, neurological decline, a decrease in quality of life, or who had died.
Approximately 27 percent have a diagnosis of heart failure. The majority suffered from three or more serious disorders of wellbeing.
Participants weighed 84 years, with about 3 percent older than 90. More than half of those listed have taken five or more medications daily.
Participants ' baseline systolic blood pressure was around 142 mmHg. The researchers split the subjects evenly into two similar groups, one group being aided in keeping their systolic readings below 140 mmHg.
The researchers tried to establish whether a more effective regulation of high blood pressure would improve the health of people, reduce their risk of heart attack problems, cognitive impairment or death, or in some way raise health risks.
The scientists were also interested in seeing how the effects of any lower systolic level would impact cognitive or physical impairments.
A decreased risk of heart attack problems and a greater probability of moderate cognitive dysfunction were shown by the population who had reached systolic values of 120 mmHg or less.
Dementia incidence was approximately the same in both classes.
People in the 120 mmHg community also had an increased frequency of improvements in their kidney function, including hospitalizations for kidney injury, which were not severe but nevertheless significant. However, most people recovered.
Thanks to extremely low blood pressure, the researchers were still worried about the risk of falls. Falls often lead to injuries and can be fatal in the elderly. Test, however, revealed that this blood pressure level did not raise the risk of a person falling.
Before the outset of the experiment, the study has looked at the effects of intensive blood pressure regulation depending on the executive ability level of each patient.
People with better executive ability experienced a greater decrease in the risk of heart failure and mortality to begin with.
While those with diminished control did not receive as much benefit, there was no evidence that their risk of heart failure or mortality decreased with the lower systolic stage.
