High blood pressure at early age predictor for heart failure

blood presureA new study published in the Journal of the American College of Cardiology has demonstrated that elevated blood pressure at an early stage is a predictor for heart failure, after the age of 50. The participants consisted of 2,479 men and women between ages 18 and 30. Their blood pressure was assessed seven times over a period of 25 years. The estimated “cumulative blood pressure exposure” was evaluated by multiplying their systolic blood pressure (when the heart is contracting) and diastolic blood pressure (between beats) at each of the seven time points by the year in which they were measured. Three percent of people younger than age 18 years have high blood pressure,

Normal blood pressure should be less than 120 millimeters of Mercury systolic over 80 nn HG diastolic. High blood pressure is diagnosed at 140/90 mmHg or more.

“Our findings provide further support for the importance of good risk factor control early in life,” said senior author Dr. Joao A.C. Lima of the cardiology division at in Baltimore, Maryland.

“Many participants were not hypertensive at the beginning of the study; however, chronic exposure to higher blood pressure, even within what is considered the normal range, is associated with cardiac dysfunction 25 years later,” he said in a news release.

The specified that by age 50, 135 of the participants had left ventricle dysfunction, in which the heart was markedly weaker at pumping blood to the body, during beats or between beats. Those who had higher blood pressure readings in their younger years, between 120/80 to 139/89 before age 30, were more likely to have left ventricular dysfunction between heartbeats than those with lower blood pressure.

“In children (high blood pressure) should elicit a careful hunt for secondary causes – especially kidney disease, endocrine and vascular problems,” Marwick said.

“Weight management, control of salt intake and are important lifestyle interventions that are important across the population,” to decrease the risk of elevated blood pressure, he said.
