Question: Who is at risk for Coronary Heart Disease? ?
Answer: In the United States, coronary heart disease (CHD) is a leading cause of death for both men and women. Each year, about 370,000 Americans die from coronary heart disease. Certain traits, conditions, or habits may raise your risk for CHD. The more risk factors you have, the more likely you are to develop the disease. You can control many risk factors, which may help prevent or delay CHD. 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 mercurythe 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 thats 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. Although older age and a family history of early heart disease are risk factors, it doesn't mean that youll develop CHD if you have one or both. Controlling other risk factors often can lessen genetic influences and help prevent CHD, even in older adults. Emerging Risk Factors Researchers continue to study other possible risk factors for CHD. High levels of a protein called C-reactive protein (CRP) in the blood may raise the risk of CHD and heart attack. High levels of CRP are a sign of inflammation in the body. Inflammation is the body's response to injury or infection. Damage to the arteries' inner walls may trigger inflammation and help plaque grow. Research is under way to find out whether reducing inflammation and lowering CRP levels also can reduce the risk of CHD and heart attack. High levels of triglycerides in the blood also may raise the risk of CHD, especially in women. Triglycerides are a type of fat. Other Risks Related to Coronary Heart Disease Other conditions and factors also may contribute to CHD, including: Sleep apnea. Sleep apnea is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. Untreated sleep apnea can increase your risk for high blood pressure, diabetes, and even a heart attack or stroke. Stress. Research shows that the most commonly reported "trigger" for a heart attack is an emotionally upsetting event, especially one involving anger. Alcohol. Heavy drinking can damage the heart muscle and worsen other CHD risk factors. Men should have no more than two drinks containing alcohol a day. Women should have no more than one drink containing alcohol a day. Preeclampsia. This condition can occur during pregnancy. The two main signs of preeclampsia are a rise in blood pressure and excess protein in the urine. Preeclampsia is linked to an increased lifetime risk of heart disease, including CHD, heart attack, heart failure, and high blood pressure.
