Research we're watching

Following a Nordic diet — which features fish, whole grains, plus fruits and vegetables popular in Scandinavian countries — may help lower the risk of stroke, a new study suggests.

The study, published in the February 2017 issue of Stroke, included more than 55,000 Danish people from a national health registry, all of whom filled out questionnaires about their diets and other lifestyle habits. Researchers looked at how closely the participants followed the Healthy Nordic Food Index, which includes six food categories: fish, apples and pears, root vegetables (such as carrots and celery root), cabbages (which also include broccoli, cauliflower, kale, and Brussels sprouts), rye bread, and oatmeal.

Lifestyle changes may reduce your need for pills.

For most of us, as the years increase, so does our blood pressure. By age 60, almost 65% of Americans will have high blood pressure. Although men are more likely to develop high blood pressure between ages 45 and 55, women are at greater risk after 65. Yet high blood pressure isn't an inevitable fact of later life. It's possible to slow the processes that drive blood pressure up. By doing so, you'll also reduce your risk of heart attack, stroke, and dementia.

Blood pressure reflects the amount of blood flowing through the vessels and the pressure exerted by the vessel walls against the blood. In a blood pressure reading, the top number represents the systolic pressure, recorded when the vessel contracts to push blood through. The bottom number represents the diastolic pressure, recorded when the vessels are relaxed. Over time, our blood vessels lose elasticity, and atherosclerotic plaque may build up in artery walls. Both of these trends make vessels stiffer. As vessels become less flexible, blood pressure is higher at any level of blood flow.

Medications for heart disease

Although lifestyle changes are an essential first step in treating coronary artery disease, you may need to take medications to reach your cholesterol and blood pressure goals and otherwise reduce your risk. In fact, most people with heart disease need to take more than one medication. The specific combination of drugs will depend on your particular symptoms and risk factors. Some of the most commonly prescribed medications are described below.

Blood pressure medications

For many years, doctors used diuretics — sometimes known as water pills — to treat high blood pressure. Although diuretics remain a mainstay of blood pressure treatment because they are cheap and effective, a flood of other drugs have become available since the 1980s. In addition, a large meta-analysis comparing the various options concluded that the five categories of drugs currently available are equally effective for most people. Work with your doctor to determine the best type of medication for you.

Heart disease is the leading cause of death among women — and one of the most preventable. Research is giving us insights into how we can control our risk.

We've come a long way since the days when a woman's worry over heart disease centered exclusively on its threat to the men in her life. We now know it's not just a man's problem. Every year, coronary heart disease, the single biggest cause of death in the United States, claims women and men in nearly equal numbers.

Risk still underappreciated

In a survey conducted by the American Heart Association, about half of the women interviewed knew that heart disease is the leading cause of death in women, yet only 13% said it was their greatest personal health risk. If not heart disease, then what? Other survey data suggest that on a day-to-day basis, women still worry more about getting breast cancer — even though heart disease kills six times as many women every year. Why the disconnect?

The predictive powers of a cholesterol test only go so far. If your LDL is low, your C-reactive protein may be a better sign of impending heart trouble.

The gap between knowing what's good for you and actually doing it can be huge, especially when it comes to something like getting exercise. (Never underestimate the appeal of the sedentary life.) Many of us need a warning-some might say a bit of a kick in the pants-before we'll change our ways and get with a heart-healthy program.

Cholesterol Tests

For decades, cholesterol testing has served as that warning for many. An elevated level of "bad" LDL cholesterol has been just the warning people needed to change their ways. It has played that role for several reasons. People like tests because the results seem objective. Reliable measurement of cholesterol is easy and relatively inexpensive. It makes sense biologically. LDL cholesterol, a protein-wrapped package containing fat and cholesterol, tends to slip out of the bloodstream and lodge in blood vessel walls, forming the plaque that leads to clots and heart attacks.

When you are alone and have to perform cardiopulmonary resuscitation (CPR), your primary effort should be compressing the chest to help the person's heart pump blood. If there is a second person helping, providing breaths can be done at the same time as compressions are performed.

The brief review of CPR on the following pages can help you in an emergency; however, this information should not take the place of a certified course in CPR.

Aspirin therapy can help prevent a second heart attack and stroke, but for otherwise healthy older men, its use depends on their 10-year risk for a heart attack or stroke as determined by their doctor. 

Shoulder pain appears to be associated with risk factors for heart disease. Researchers found that people with the most heart disease risk factors, like high cholesterol, high blood pressure, and diabetes, were almost five times more likely to also have shoulder trouble. 

Paying attention to your eating habits and other lifestyle routines can help nudge down the number on the scale.

If you're like many Americans, you're still carrying an extra pound or two that you gained over the holidays. Over the years, that extra weight can really add up—and that added girth is hard on your heart.

Often, the hardest part about losing weight isn't about knowing what to eat. You've heard it a thousand times: eat lots of vegetables, fruits, whole grains, and lean protein. The real challenge is changing your habits to make those healthy choices part of your everyday routine without feeling too deprived.
