Celebrate America Heart Month by managing health risks

Feb. 6, 2013 |

By Dr. Murray Mittleman physicianfocus@mms.org February is American Heart Month. On Valentine's Day, people typically think about the ones they love and the need to take care of their hearts. However, as heart disease remains the leading cause of death among American men and women, people must be good to our hearts year round. That responsibility includes keeping up with the latest medical studies that teach how to minimize cardiovascular risk and optimize heart health. A broken heart Experts have known for some time that grief over the death of a loved one is associated with depression, anxiety, and anger. Current research supports the idea that bereavement is also linked to higher risks for heart attacks. A recent study showed that heart attack risks increased 21 times within a day after the death of a significant other. Risks were also almost six times higher after the first week of death. This study is important for those who are grieving, as well as their caretakers and healthcare providers, who should understand the increased level of vulnerability brought on by emotional loss. There should be heightened awareness about heart attack signs like chest discomfort, upper body pain, shortness of breath, cold sweats, nausea, or lightheadedness. Any of these symptoms require prompt medical attention. Those affected should also seek social and psychological intervention as needed. What's heart healthy Reports frequently highlight the benefits of a heart-healthy diet and cardiovascular exercise, but what impact does coffee, chocolate, and alcohol have on the heart? While the American Heart Association warns about excessive coffee consumption, the latest research shows a protective benefit. The strongest protection against heart failure came with two eight-ounce servings of coffee per day. However, protection decreases beyond two cups and may cause harm when more than five cups a day are consumed. Drinking coffee also lowers the risk for Type 2 diabetes. When consumed in moderation, there's no negative effect on blood pressure for most people. Chocolates contain flavonoids that act as antioxidants to protect the body from free radicals, which can lead to heart disease. Flavonoids may also reduce the risk of high blood pressure and atherosclerosis (hardening of the arteries), as well as heart attacks. In one study, people who ate chocolate once a week had a 44 percent lower risk of heart failure, while those who indulged twice a week reduced their risk by 66 percent. Preferred portion size is about one-fourth of a regular-sized chocolate bar, and the darker the chocolate, the better. The heart-healthiest dark chocolate has at least 60 percent cocoa solids. However, chocolate is a high-calorie, high-fat food. A typical 1.5 ounce of dark chocolate can contain as many as 220 calories, 17 grams of fat, and 23 grams of carbs moderation is key. What about alcohol? Many studies show that light-to-moderate drinking can be good for the heart, but more than two drinks for men or one for women per day may increase the chance of health problems. What to avoid The traditional risk factors associated with heart disease are: smoking, sedentary lifestyle, and poor diet. New research shows findings concerning the physical, psychological, and chemical triggers of acute cardiovascular events. Regular exercise is one of the most important ways to stay healthy and decrease risk of heart disease. But, strenuous activities like snow shoveling, particularly for habitually sedentary people at increased cardiac risk, is not advisable. Patients with heart disease should talk with their physicians to discuss the safest way to begin a new exercise program. Evidence shows that anger, depression, anxiety, and work stress may lead to heart attacks, as can events outside of our control like environmental disasters and terrorist activity. Finally, chemical triggers like binge drinking, heavy meals, and cocaine and marijuana use can all precipitate heart attacks. The best way to avoid a heart attack caused by these types of stressors is to keep your risk factors under control. Quit smoking and avoid second-hand smoke, eat a balanced, heart healthy diet, exercise regularly, and have your blood pressure and cholesterol checked and maintained through lifestyle changes and medications if needed. What's the takeaway this season and throughout the year? Review the latest research, consider your risk factors, and practice moderation.
