heart attack risk
The next time you have your blood pressure checked, ask your health care to check it in both arms, rather than just in one. Why? A big difference between the two readings can give you an early warning about increased risk of cardiovascular disease, a new study suggests. Harvard researchers found that people who have a 10-point difference in blood pressure from one arm to the other are 38% more likely to have a heart attack, stroke, or a related problem than those with arm-to arm differences less than 10 points. Small differences in blood pressure readings between the right and left arm are normal. But large ones suggest the presence of artery-clogging plaque in the vessel that supplies blood to the arm with higher blood pressure. Clogging there means there’s a good chance the arteries in the heart and brain are also clogged, boosting the odds of having a heart attack or stroke.
