(MENAFN- The Arabian Post)

The American Heart Association has made significant changes to its blood pressure guidelines, sparking discussions among health experts about the implications for treatment and prevention. Under the revised norms, a blood pressure reading of less than 120/80 mm Hg is now considered optimal. Previously, figures above this threshold were seen as the standard for healthy adults. This revision is expected to influence how blood pressure is monitored and managed across healthcare systems worldwide.

The AHA's new guidelines are part of a growing recognition of the importance of managing blood pressure earlier in life to prevent cardiovascular diseases. According to the guidelines, any reading above 130/80 mm Hg is now classified as high blood pressure, a departure from earlier thresholds that considered a higher range acceptable. Experts argue that the shift reflects an evolving understanding of how even modest increases in blood pressure can raise the risks for heart attacks, strokes, and kidney damage over time.

For cardiologists and healthcare professionals, these changes mean revisiting how patients are monitored, diagnosed, and treated. Dr. Maria Jensen, a leading cardiologist, notes that the new norm represents a shift towards more aggressive intervention and preventative measures.“By setting a lower threshold, we're essentially targeting individuals who previously might not have been seen as at risk,” she explains. The goal is to identify high blood pressure in its early stages and take steps to prevent more serious conditions down the line.

However, the revised guidelines are not without controversy. Some critics argue that the new norms could lead to overdiagnosis and unnecessary treatment. Concerns have been raised that a large number of healthy individuals might be classified as hypertensive, leading to the prescription of medications that they may not need. These concerns are not new-similar debates have arisen when other health guidelines have shifted, such as the cholesterol treatment thresholds in the early 2000s.

For many health experts, the worry is that this may encourage“medicalisation” of what was once considered a natural part of the aging process.“Setting an overly cautious threshold risks making people overly anxious about their health,” says Dr. Liam O'Connor, a professor of medicine. He acknowledges the importance of managing high blood pressure but cautions that the new guidelines could drive up unnecessary healthcare costs, particularly in the US, where medication adherence can be inconsistent.

The AHA's decision to lower the bar aligns with global health trends, especially in developed nations where non-communicable diseases like heart disease and stroke remain leading causes of death. Studies indicate that even modest reductions in blood pressure could significantly lower mortality rates from these conditions. As a result, the focus on early intervention is seen as an essential step towards improving long-term health outcomes.

Dr. Jensen emphasizes the broader impact of the new guidelines.“By diagnosing high blood pressure earlier, we can help patients make lifestyle changes that may reduce their risk without the need for medication,” she says. Lifestyle modifications such as weight loss, a balanced diet, and increased physical activity have long been proven to be effective in managing blood pressure. The new guidelines underscore the role of lifestyle interventions before resorting to pharmacological solutions.

The AHA's guidelines also come at a time when more people are turning to wearable technology to track their health metrics, including blood pressure. Innovations in home monitoring devices have made it easier for individuals to keep an eye on their readings, and these tools are increasingly being recommended for those who fall within the grey area of pre-hypertension. As wearable tech continues to evolve, experts believe it could help bridge the gap between medical consultations and everyday self-monitoring, giving individuals a greater sense of control over their health.

However, as the AHA's revised guidelines gain traction, experts warn that a focus on blood pressure alone may not be sufficient. Dr. O'Connor points out that other factors like stress, diet, and genetics play critical roles in cardiovascular health. A multifaceted approach, he argues, is essential for achieving the broader goals of reducing the global burden of heart disease.

Global health organisations such as the World Health Organization are monitoring these changes closely, as they could set a precedent for how blood pressure is defined and treated worldwide. The AHA's guidelines may influence policies and practices in other countries, especially where hypertension is prevalent but undertreated. According to WHO, nearly 1.13 billion people worldwide suffer from hypertension, with many unaware of their condition.
