Who really needs cholesterol and blood pressure drugs?
Consumer Reports by the editors of Consumer Reports
Experts agree that high blood pressure and high cholesterol increase the risk of having a heart attack. So you might think they also agree on when you should take drugs to control them. They don’t, says Consumer Reports. Earlier this year, the American College of Physicians issued more lenient guidelines for blood pressure in people 60 and older: They don’t need drugs until their systolic, or upper, blood pressure number goes above 150, the ACP now says. But the American Heart Association sticks with the traditional cutoff of 140. And last year, the U.S. Preventive Services Task Force suggested that people who don’t have particularly high cholesterol levels can still benefit from cholesterol-lowering statin drugs.
Here’s Consumer Reports’ guide through the maze.
— Focus on your overall risk. Though blood pressure and cholesterol levels are important, other factors play a role, too — including your age, gender, race, and whether you smoke or have diabetes.
“Everyone 40 and over should know their overall risk of having a heart attack or stroke,” says Marvin M. Lipman, M.D., Consumer Reports’ chief medical adviser. So he and other experts recommend estimating your 10-year risk by using a calculator developed by the American College of Cardiology and the American Heart Association, at tools.acc.org/ascvd-risk-estimator. The ideal is a 10-year risk that’s less than 7.5 percent.
— Don’t rush to drugs. If your 10-year risk is greater than 10 percent, or if your LDL (bad) cholesterol level is over 190, you should start a statin. But if your risk is between 7.5 and 10, it can be worth trying lifestyle changes first, Consumer Reports’ consultants say.
That means stopping smoking, losing excess weight, being active, consuming a heart-healthy diet, drinking alcohol in moderation only and getting blood sugar levels under control. If that doesn’t lower your risk enough after three to

six months, consider a statin, even if your LDL cholesterol isn’t elevated.
The same basic strategy applies to blood pressure. If it’s moderately elevated (150 to 160 for people 60 and older; 140 to 150 for others), consider drugs only if several months of diet and lifestyle changes weren’t enough.
— Get the right medication. People with a history of heart attack or stroke,
or at very high risk of one (greater than 20 percent), should start with higher doses of a potent statin: 40 to 80 mg of atorvastatin (Lipitor and generic) or 20 to 40 mg of rosuvastatin (Crestor and generic).
Doctors use several different kinds of drugs to lower blood pressure, and for people with levels above 150 it can take a combination to control the problem.
Still, it usually makes sense to start with the oldest, safest and least expensive drug: diuretics, or water pills, such as chlorthalidone or hydrochlorothiazide. If that doesn’t work, you may need to switch to or add an ACE inhibitor, calcium channel blocker, or other kind of drug.
