Arterial pressure is conventionally measured using two numerical figures. The systolic figure reflects the force exerted by the heart as it propels blood through the vessels, while the diastolic figure indicates the pressure within the arteries during the time between heartbeats, when the organ is at rest. Previously, medical professionals deemed both readings important, aiming to keep them within expected parameters.
Researchers hailing from the National University of Ireland in Galway reviewed data spanning over 47,000 patients from various nations and arrived at a surprising conclusion: low diastolic pressure poses no significant health hazard, contrasting sharply with elevated systolic pressure. Based on this evidence, scientists advise concentrating efforts on maintaining the upper reading within the 100–130 mmHg range, without undue concern regarding a drop in the lower number.
This finding has the potential to reshape how hypertension is managed. Clinicians can now place a greater emphasis on lowering systolic pressure, thereby improving the efficacy of cardiovascular complication prevention.
Nevertheless, experts stress that avoiding hypertension in the first place remains paramount. Sustaining a healthy body mass, adopting a well-rounded diet rich in vegetables, fruits, whole grains, and lean protein, along with moderating salt and alcohol intake, all contribute positively to blood pressure regulation. Consistent physical activity, quitting smoking, managing stress levels, and routinely checking pressure readings allow for the timely detection of deviations and the averting of complications.
According to Dr. Bill McEvoy, the principal author of the study featured in the journal Circulation, prioritizing the systolic measurement could substantially enhance cardiovascular disease prevention and extend patient longevity.
