Coronary artery diseaseCoronary artery disease is America's No.1 killer, affecting more than 13 million Americans. The arteries, which start out smooth and elastic, get plaque on their inner walls, which can make them more rigid and narrowed. This restricts blood flow to your heart, which can then become starved of oxygen.The plaque could rupture, leading to a heart attack or sudden cardiac death. Md, W. (n.d.). Coronary Artery Disease.

Enlarged Heart (Cardiomegaly)An enlarged heart may have several causes. But it's usually the result of high blood pressure or coronary artery disease. It may not pump blood effectively, which can bring congestive heart failure. It may improve over time. But most people with an enlarged heart need life-long treatment with medications. Md, W. (n.d.).

Heart valve diseaseYour heart valves lie at the exit of each of your four heart chambers and maintain one-way blood flow through your heart. The four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage. A leaky valve occurs when a valve does not close tightly. If the valves do not seal, some blood will leak backwards across the valve. As the leak worsens, the heart has to work harder to make up for the leaky valve, and less blood may flow to the rest of the body. Md, W. (n.d.). Heart Valve Disease.

Heart Attack
- A million Americans have heart attacks each year. A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle.
- The heart muscle requires a constant supply of oxygen-rich blood to nourish it. The coronary arteries provide the heart with this critical blood supply. If you have coronary artery disease, those arteries become narrow and blood cannot flow as well as they should.
- When the plaque is hard, the outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. If a blood clot totally blocks the artery, the heart muscle becomes "starved" for oxygen. Within a short time, death of heart muscle cells occurs, causing permanent damage. This is a heart attack.

Cardiomyopathy
Cardiomyopathy, or heart muscle disease, is a type of progressive heart disease in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart's ability to pump blood is weakened, often causing heart failure and the backup of blood into the lungs or rest of the body. There are three main types of cardiomyopathy - dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy.

Marfan Syndrome
- Marfan syndrome is an inherited disease that affects the body's connective tissue, which provides the strength, support, and elasticity to tendons, cartilage, heart valves, blood vessels, and other vital parts of the body.
- For people with Marfan syndrome, the connective tissue lacks strength due to its abnormal chemical makeup. The syndrome affects the bones, eyes, skin, lungs, and nervous system along with the heart and blood vessels. The condition is fairly common, affecting 1 in 5,000 Americans. It is found in people of all races and ethnic backgrounds.
- One of the biggest threats of Marfan syndrome is damage to the aorta, the artery that carries blood from the heart to the rest of the body. Marfan syndrome can rupture the inner layers of the aorta, causing dissection that leads to bleeding in the wall of the vessel. Aortic dissection can be deadly. Surgery may be required to replace the affected part of the aorta.
- Marfan syndrome is caused by a change in the gene that controls how the body makes fibrillin, an essential component of connective tissue that contributes to its strength and elasticity.
- In most cases, Marfan syndrome is inherited from a parent, but 1 in 4 cases occurs in people with no known family history of the disease. It occurs equally in men and women, who have a 50% risk of passing on the gene to their children. Marfan syndrome is present at birth, but may not be diagnosed until adolescence or later. Everyone with Marfan syndrome has the same defective gene, but not everyone experiences the same symptoms to the same degree.
