110/64 blood pressure Let us know
110/64 blood pressure..This study, called the “Systolic Blood Pressure Intervention Trial,” or SPRINT, suggests that a blood pressure level that is much lower than what is currently recommended for some people can greatly reduce heart failure. heart failure and deaths due to heart problems.
110/64 blood pressure
However, many experts, including ours at Consumer Reports Best Buy Drugs, believe it is unknown whether the SPRINT findings are relevant to most people with high blood pressure. That’s because the study looked at only a small subset of people who have high blood pressure and are at high risk.
Old questions, new answers
If you have been diagnosed with hypertension, it is important to keep your blood pressure at a healthy level. Uncontrolled blood pressure causes more heart attacks and strokes in the United States than any other cause. But how low is low enough?
Under current guidelines, the ideal is a systolic pressure (the highest number) of 120 millimeters of mercury or less and a diastolic pressure (the lowest number) of 80 mmHg or less. It is considered that one has high blood pressure if the systolic pressure reaches 140 or the diastolic pressure reaches 90 or exceeds it.
However, experts have long debated whether those who have high blood pressure need to lower their levels to the ideal limits or if reaching a point below the high blood pressure limit is sufficient.
The SPRINT study sought to end this debate and, at first glance, the result suggests that targeting below is healthier. This is the reason: The trial, funded by the government, included more than 9,300 people with high blood pressure and a high risk of heart attack. Participants received medications to reduce their blood pressure.
Approximately half of them tried to reduce their systolic pressure to 120; the other half stuck to a goal of 140.
The study was scheduled to last for 5 years, but stopped after just over 3 years because the results were dramatic. During that period, 65 people in the group who were trying to reach a systolic pressure of 140 died and 100 had heart failure.
Among those trying to reach a systolic pressure of 120, only 37 died and 62 developed heart failure, the researchers reported in the New England Journal of Medicine.
Dr. Gary Gibbons, M.D., director of the National Heart, Lung and Blood Institute (NHLBI), the main sponsor of the SPRINT study, said the findings will change the way high blood pressure is treated and lives will be saved.
However, the benefits are accompanied by considerable disadvantages. In order to reduce their blood pressure to 120, people who participated in the study had to take on average three medications for blood pressure.
That led to almost double instances of serious side effects including some that required emergency care in the hospital, such as kidney failure, dangerously low blood pressure and imbalances in sodium and potassium levels in the blood.
In addition, many people have trouble taking their blood pressure medications consistently and an additional pill could increase those difficulties, says Dr. Michael Pignone, MD, director of internal medicine at the University of North Carolina’s School of Medicine in Chapel. Hill.
In fact, because of side effects, the need to cut costs and / or other factors, up to half of people stopped taking their high blood pressure medications in less than a year. “Giving more medication to a person if they are not consistently taking their current regimen is not a useful strategy,” says Dr. Pignone.
Who does this study affect?
SPRINT focused on a specific group of people with hypertension: people 50 years of age and older with at least one more chronic disease, such as heart disease or kidney disease (both raise the risk of heart attack and stroke), and people with 75 years and older Only 1 in 6 people from high blood pressure belongs to one of these high-risk groups.
If you belong to one of them, Dr. Harlan Krumholz, M.D., a cardiologist at Yale University, recommends talking to your doctor about whether reducing your systolic blood pressure to 120 deserves the risk. Otherwise, he adds, it may not be necessary to reduce your goal to 120, based on these new findings.
Talk to your doctor about the possibility of making important changes to your lifestyle that can help lower your blood pressure (see the section “Try your lifestyle changes first” below). These changes are particularly important for people like those who are part of the group studied in SPRINT.
For the rest of us …
If you are not in one of the high risk categories mentioned above, what should your blood pressure levels be? Our medical experts consider that 150/90 is a reasonable target for most people between 60 and 75 years old who have other risk factors. Meanwhile, for people under 60, people with diabetes and people under 50 with chronic kidney disease, suggested a goal of 140/90.
These figures are based on recommendations from an independent panel of experts convened by the NHLBI. The panel noted that reaching levels below 140/90 may require additional medications for blood pressure or high doses. This increases the risk of the aforementioned side effects and, depending on the medication, problems such as persistent cough, erectile dysfunction and frequent urination.
