American Heart Month: Heart Disease is Number One Killer
Heart disease is the leading cause of death in the United States, killing more than 600,000 people each year, according to the Centers for Disease Control and Prevention (CDC).
The term “heart disease” refers to several types of heart conditions. The most common type is coronary artery disease (CAD), which can cause heart attack. Other kinds of heart disease may involve the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.
Anyone, including children, can develop heart disease. It occurs when a substance called plaque builds up in your arteries. Too much plaque buildup and narrowed artery walls can make it harder for blood to flow through your body. When your heart muscle doesn’t get enough blood, you may have chest pain or discomfort, called angina. Angina is the most common symptom of CAD.
Over time, CAD can weaken the heart muscle. This may lead to heart failure, a serious condition where the heart can’t pump blood the way that it should. An irregular heartbeat, or arrhythmia, also can develop. When this happens, your arteries can narrow over time, reducing blood flow to the heart.
According to ARH Cardiologist Pablo Lopez, M.D., once you get heart disease, you will always have it. “There are effective medicines to slow the progression and procedures which can help blood and oxygen flow to the heart, but arteries remain damaged,” Lopez explained. “Also keep in mind the condition of your blood vessels will steadily worsen unless you make changes in your daily habits, take your medicines and control your risk factors.”
Major Risk Factors
Unhealthy blood cholesterol levels. This includes high LDL cholesterol (sometimes called “bad” cholesterol) and low HDL cholesterol (sometimes called “good” cholesterol).
High blood pressure. Blood pressure is considered high if it stays at or above 140/90 mmHg over time. If you have diabetes or chronic kidney disease, high blood pressure is defined as 130/80 mmHg or higher. (The mmHg is millimeters of mercury—the units used to measure blood pressure.)
Smoking. Smoking can damage and tighten blood vessels, lead to unhealthy cholesterol levels, and raise blood pressure. Smoking also can limit how much oxygen reaches the body's tissues.
Insulin resistance. This condition occurs if the body can't use its own insulin properly. Insulin is a hormone that helps move blood sugar into cells where it's used for energy. Insulin resistance may lead to diabetes.
Diabetes. With this disease, the body's blood sugar level is too high because the body doesn't make enough insulin or doesn't use its insulin properly.
Overweight or obesity. The terms “overweight” and “obesity” refer to body weight that’s greater than what is considered healthy for a certain height.
Metabolic syndrome. Metabolic syndrome is the name for a group of risk factors that raises your risk for CHD and other health problems, such as diabetes and stroke.
Lack of physical activity. Being physically inactive can worsen other risk factors for CHD, such as unhealthy blood cholesterol levels, high blood pressure, diabetes, and overweight or obesity.
Unhealthy diet. An unhealthy diet can raise your risk for CHD. Foods that are high in saturated and trans fats, cholesterol, sodium, and sugar can worsen other risk factors for CHD.
Older age. Genetic or lifestyle factors cause plaque to build up in your arteries as you age. In men, the risk for coronary heart disease increases starting at age 45. In women, the risk for coronary heart disease increases starting at age 55. A family history of early coronary heart disease is a risk factor for developing coronary heart disease, specifically if a father or brother is diagnosed before age 55, or a mother or sister is diagnosed before age 65.
Regarding these risk factors, Lopez emphasized: “Pay attention to these health factors and talk to your healthcare provider about making necessary changes to your lifestyle so you can improve your heart health.”
Your healthcare provider can determine your risk of heart attack, and can provide information about various tools you can use to protect your heart, including smoking cessation programs, an exercise regimen, nutrition counseling, blood pressure screenings and cholesterol testing.
