write a two hundred-word essay on health behaviors, risk factors, and prevention of coronary artery disease (CAD) through exercise.
Risk factors often occur in clusters and may build on one another, such as obesity leading to diabetes and high blood pressure. When grouped together, certain risk factors put you at an ever greater risk of coronary artery disease. [ For example, metabolic syndrome — a cluster of conditions that includes elevated blood pressure, high triglycerides, elevated insulin levels and excess body fat
around the waist — increases the risk of coronary artery disease.
Sometimes coronary artery disease develops without any classic risk factors. Researchers are studying other possible factors, including:
Sleep apnea. This disorder causes you to repeatedly stop and start breathing while you're sleeping. Sudden drops in blood oxygen levels that occur during sleep apnea increase blood pressure and strain the cardiovascular system, possibly leading to coronary artery disease.
C-reactive protein. C-reactive protein (CRP) is a normal protein that appears in higher amounts when there's swelling somewhere in your body. High CRP levels may be a risk factor for heart disease. It's thought that as coronary arteries narrow, you'll have more CRP in your blood.
Homocysteine. Homocysteine is an amino acid your body uses to make protein and to build and maintain tissue. But excessive levels of homocysteine may increase your risk of coronary artery disease and other cardiovascular CRP conditions.
Fibrinogen. Fibrinogen is a protein in your blood that plays a central role in blood clotting. But too much may increase clumping of platelets, the type of blood cell largely responsible for clotting. That can cause a clot to form in an artery, leading to a heart attack or stroke. Fibrinogen may also be an indicator of the inflammation that accompanies atherosclerosis.
Lipoprotein (a). This substance forms when a low-density lipoprotein (LDL) particle attaches to a specific protein. Lipoprotein (a) may disrupt your body's ability to dissolve blood clots. High levels of lipoprotein (a) may be associated with an increased risk of cardiovascular disease, including coronary artery disease and heart attack. ]
