High Blood Pressure – Main Cause for Cardiovascular Disease

Nearly three-quarters of adults in the United States with conditions such as coronary heart disease, stroke and diabetes also have high blood pressure, according to researchers.

The study was based on analyzing data from 4.646 adults who took part in the U.S. National Health and Nutrition Examination Survey, a massive ongoing research project. Researchers at the University of California, Irvine, led by Nathan D. Wong, Ph.D. draw attention to how commonplace high blood pressure has become.

About 1.671 (31.4 percent) of the participants had high blood pressure, the researchers found. Older or black adults seem to be the most exposed to hypertension. About 68.5 percent of people with high blood pressure were receiving medication for the condition and 52.9 percent had their hypertension under control.

"You get high blood pressure by leading an unhealthy lifestyle, so it often goes hand in hand with chronic conditions," said Norm Campbell, president of Blood Pressure Canada.

Healthy adults should have a blood pressure of 120/80 millimetres of mercury (mmHg) or better, according to specialists. A person suffers from hypertension when its blood pressure is 140/90 or higher.

The study found that most people suffering from cardiovascular diseases and related problems had high blood pressure, including: 76.8 percent of those with diabetes; 81.8 percent of those with chronic kidney disease; 69.5 percent of those with stroke; 71.4 percent of those with congestive heart failure; 73.7 percents of those with peripheral artery disease or narrowed veins or arteries; 73 percent of those with coronary artery disease and 76.9 percent of those with two or more of these diseases.

According to Dr. Campbell, “most countries are struggling with these same problems.” Moreover, worldwide, high blood pressure is one of the leading causes of death.

“These high-risk persons with low rates of hypertension control represent an urgent need for intensified efforts to achieve blood pressure control,” was the conclusion of the study.

The findings were published in the December 10’s issue of the Archives of Internal Medicine.
