Revised Blood Pressure Guidelines Advise Stricter Control, Encourage Alcohol Abstinence and Healthy Lifestyle for Heart Disease Prevention

In an update to previous guidelines, the American Heart Association and American College of Cardiology now recommend a more proactive approach to managing high blood pressure. These updated recommendations were released on Thursday and offer new perspectives on the importance of maintaining optimal blood pressure levels.

High blood pressure is a significant global concern as it is the leading cause of death worldwide. By controlling blood pressure, individuals can lower their risk of heart disease, kidney disease, type 2 diabetes, and dementia. Notably, about half of all adults in the United States currently have high blood pressure.

Blood pressure readings are measured in millimeters of mercury (mm Hg) and consist of both a systolic (upper) reading and a diastolic (lower) reading. The goal blood pressure for adults remains unchanged, with normal blood pressure being less than 120/80 mm Hg. However, if an individual’s blood pressure is 130/80 mmHg or higher, medical providers will encourage lifestyle changes and potentially medication to reach the desired level.

The new guidelines emphasize a more aggressive approach to controlling high blood pressure. For individuals with systolic blood pressure ranging from 130 to 139, medical providers will initially encourage adopting healthy lifestyle habits. If these changes do not lower blood pressure within three to six months, medication may be recommended. This represents a shift from the 2017 guidelines, which suggested that anyone with systolic blood pressure above 140 should be prescribed both lifestyle changes and medication.

Lifestyle modifications advised by the new guidelines include maintaining a healthy weight, following a heart-healthy diet, reducing salt intake, managing stress, engaging in at least 150 minutes of moderate physical activity per week, and incorporating resistance exercise like weight training.

The updated recommendations also suggest abstaining from alcohol consumption due to the negative impact it has on blood pressure. Previous guidelines permitted moderate drinking for women (one drink or less per day) and men (two drinks or less per day), but the new guidelines emphasize that there is too much evidence linking alcohol to increased blood pressure levels.

The revised guidelines also place greater emphasis on reducing blood pressure to minimize the risk of developing dementia, citing mounting evidence supporting this correlation. Additionally, they highlight the importance of monitoring blood pressure for individuals planning pregnancy or those who are currently pregnant due to the potential negative effects high blood pressure can have on both mother and fetus.

The DASH diet (Dietary Approaches to Stop Hypertension) remains a recommended approach, consisting of increased consumption of fruits, vegetables, whole grains, fish, poultry, beans, nuts, and vegetable oils, while limiting intake of fat, sugar, and tropical oils such as coconut and palm oil.

The guidelines also advocate for reducing sodium intake to less than 2,300 mg per day, with an ideal goal of 1,500 mg per day. Potassium-enriched salt substitutes can be used at home as a simple way to increase potassium intake while limiting sodium consumption.

For individuals with overweight or obesity, the guidelines recommend aiming to lose at least 5% of body weight. For those with more severe obesity, clinically proven interventions such as diet and exercise, weight loss medications including GLP-1s, and surgery may be suggested.

Dr. Daniel Jones, American Heart Association chair of the writing committee for the guidelines, acknowledges the challenges individuals face in managing their blood pressure but stresses that implementing these steps can significantly improve overall health. He notes that while maintaining a healthy diet in today’s environment can be difficult, the benefits are worth the effort.
