Harvard Health Publications Focus On Blood Pressure: Part 4

How to measure your blood pressure at home Last week's issue of Focus On: Blood Pressure discussed the many benefits of measuring your blood pressure at home. This article gives you the practical tips you need to make sure you do it right. Picking the right machine There are dozens of different home blood pressure monitors on the market. For best accuracy and ease of use, buy one with a cuff for the upper arm that automatically inflates and automatically records the pressure. The American Heart Association doesn't recommend wrist or finger home blood pressure monitors. Models that store readings for a week or two can simplify record keeping. The British Hypertension Society lists machines they recommend on their Web site: http://www.bhsoc.org/blood_pressure_list.stm. And the September 2008 issue of Consumer Reports compared home blood pressure and blood sugar monitors. The ReliOn HEM-74CREL ($50) got a "best buy" rating, while the Omron Elite 7300W ($75 to $100) was the top-rated machine. Do it right When it comes to measuring blood pressure, technique matters. Doing it wrong can give you a reading that's too high or too low. (See a brief video on using a home blood pressure monitor.) Taking your blood pressure at home To get the most accurate blood pressure reading, support your arm at heart level, wrap the cuff around your bare upper arm, and follow the directions on your machine. There are two things to do before you start. First, check your machine against the one in your doctor's office. Second, make sure you have the right size cuff—the inflatable part should encircle at least 80% of your upper arm. When you first start to check your blood pressure at home, measure it early in the morning, before you have taken your blood pressure pills, and again in the evening, every day for a week. After that, follow the plan your doctor recommends, or check it one or two days a month. Each time you take a reading:
Checking blood pressure at home won't cure hypertension, but it will help control the most common cause of stroke and a big contributor to heart attack, heart failure, and premature death. | ||||||||||||||||||||

Harvard Health Publications Focus on Cholesterol: Part 4

Should you take a statin even if you have normal cholesterol? The statin drugs are best known for their ability to lower LDL ("bad") cholesterol. High levels of LDL cholesterol can lead to heart disease. If your LDL cholesterol is not high, you probably think you don't need to take a statin. But a study nicknamed JUPITER may make you—and your doctor—question that assumption. The JUPITER trial The JUPITER trial was a large international study that found that the statin drug rosuvastatin (Crestor) slashed the rate of heart attacks and strokes in people with normal LDL cholesterol who had elevated levels of C-reactive protein (CRP). CRP is a marker of inflammation, and there is increasing evidence that low-grade inflammation raises heart risk. The study involved 17,802 apparently healthy people from 26 countries. There were slightly more men than women—about a 60%-40% split. Here are some of their stats:
Subjects were randomly assigned to take either 20 mg of Crestor or a placebo pill daily. They were monitored for cardiovascular events—heart attacks, strokes, bypass surgery or angioplasty, hospitalization for unstable angina, and death from a cardiovascular cause. The results JUPITER was designed to last for four years, but it was halted just short of two years because the statin takers were doing so much better than those taking the placebo. For example, people taking a statin:
In the placebo group, CRP levels and LDL levels did not change. Side effects, such as muscle pain and problems with liver or kidney function, were the same in the two groups. However, there may have been an increase in diabetes among those taking Crestor. Results of the study were published in The New England Journal of Medicine (online Nov. 9, 2008, and in print Nov. 20, 2008). Some caveats
What this means to you Should you get an hsCRP test? The answer depends on your overall cardiovascular risk. The time-honored Framingham model uses age, cholesterol levels, blood pressure, smoking status, and diabetes to calculate a person's 10-year chance of having a heart attack. To calculate your Framingham risk score, go to www.nhlbi.nih.gov/guidelines/cholesterol/risk_tbl.htm. If your risk is high... You probably don't need the hsCRP test because you should be taking a statin anyway. If your risk is low... You probably don't need the test because it's still not clear that the benefit outweighs the cost and possible risk. If your risk is moderate... HsCRP results might help determine whether a statin, in addition to lifestyle changes, could reduce your risk of a heart attack or stroke. Talk to your doctor about it. If you do get a CRP test, you can then reassess your cardiovascular risk using the newer Reynolds model (www.reynoldsriskscore.org). Unlike the Framingham tool, the Reynolds model adds hsCRP and some other factors to predict cardiovascular risk. The model reclassifies many people whose Framingham scores place them at moderate risk—sometimes into a higher risk category, sometimes into a lower risk one. Your reason for taking a statin should still be your risk of having a heart attack. To find out about current LDL cholesterol goals and when you should consider taking a statin, consult the Adult Treatment Panel III Guidelines developed by the U.S. National Cholesterol Education Program, available at www.nhlbi.nih.gov/guidelines/cholesterol/atglance.htm. Statins have revolutionized cardiovascular disease prevention, and you should certainly take one if you have the appropriate risk factors. But also do everything you can to keep your statin dose low through exercise and diet to lower your LDL cholesterol. | ||||||||||||||||||||||||||
