Newswise — For people with heart disease, lowering even "normal" blood pressure can reduce the chances of having a heart attack, stroke, severe chest pain, or the need for a procedure to open coronary arteries, according to the Harvard Heart Letter.
An international study that included 2,000 people with heart disease and an average blood pressure of 129/78 — a reading that would be considered normal in almost any doctor's office — found that those who took either of two blood pressure medications not only lowered their blood pressures but fared better health-wise as well, compared with those taking a placebo. People taking the medications were less likely to die of cardiovascular disease, experience a nonfatal heart attack or stroke, need bypass surgery or angioplasty, or be hospitalized for chest pain. The Harvard Heart Letter explains that while the differences between the treated groups and placebo group were not huge, applying the findings to the millions of people with heart disease and near-normal blood pressure could save thousands of lives and procedures.
According to the Harvard Heart Letter, this study suggests that the 2003 national guideline for hypertension, which set a newer, stricter cutoff for a healthy blood pressure, is right on target. What's more, it points out that for people with heart disease, "the lower the better" applies as much to blood pressure as it does to cholesterol.
The February issue of the Harvard Heart Letter also touches on the classic symbol used to represent the heart. The fist-sized muscle in the chest looks nothing like the "heart-shaped" image that adorns the cards and candy boxes we see especially at this time of year. The article explores how the shape of the human heart came to be represented around the world as the pointy-bottomed, smooth-sided, cleft-topped icon drawn by artists, greeting card makers, and lovestruck doodlers.
