Diabetes or insulin resistance Sedentary lifestyle Once the inner wall of an artery is damaged, fatty deposits plaque made of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of the plaque breaks or ruptures, blood cells called platelets will clump at the site to try to repair the artery.
Take the Heart Disease Quiz! What Causes Valvular Heart Disease? Sometimes the cause of valve disease is unknown. Most often affects the aortic or pulmonic valve.
Valves may be the wrong size, have malformed leaflets, or have leaflets that are not attached to the annulus correctly.
Bicuspid aortic valve disease is a congenital valve disease that affects the aortic valve. Instead of the normal three leaflets or cusps, the bicuspid aortic valve has only two. Without the third leaflet, the valve may be stiff unable to open or close properly or leaky not able close tightly.
This includes problems that develop with valves that were once normal. These may involve changes in the structure or your valve due to a variety of diseases or infections, including rheumatic fever or endocarditis.
Rheumatic fever is caused by an untreated bacterial infection usually strep. Luckily, the introduction of antibiotics to treat this infection has dramatically reduced the numbers of this infection. The initial infection usually occurs in children, but the heart problems associated with the infection may not be seen until years later.
At that time, the heart valves become inflamed, the leaflets stick together and become scarred, rigid, thickened and shortened. This leads to mitral regurgitation. Endocarditis occurs when germs, especially bacteria, enter the bloodstream and attack the heart valves, causing growths and holes in the valves and scarring.
This can lead to leaky valves. The germs that cause endocarditis enter the blood during dental procedures, surgery, IV drug use, or with severe infections. There are many changes that can occur to the valves of the heart.
The chordae tendinea or papillary muscles can stretch or tear; the annulus of the valve can dilate become wide ; or the valve leaflets can become fibrotic stiff and calcified. Mitral valve prolapse MVP is a very common condition, affecting 1 to 2 percent of the population.
MVP also causes the tissues of the valve to become abnormal and stretchy, causing the valve to leak.Coronary artery disease, congestive heart failure, heart attack-- each type of heart problem requires different treatment but may share similar warning signs.
It is important to see your doctor so. Coronary heart disease (CHD) is currently the leading cause of death among adults in the U.S. — and according to the Centers For Disease Control and Prevention (CDC), it has maintained this ranking as the No. 1 killer since (1) Coronary heart disease is a condition caused by the buildup of.
Chest pain from the heart muscle because it doesn’t have adequate oxygen and nutrient-rich arterial blood flow, also called angina, is a common symptom of heart disease.
Coronary artery disease (CAD) is a condition that impairs and reduces blood flow through your coronary arteries. These arteries supply blood to the heart muscle.
When blood flow to the heart. Myocardial infarction (MI) refers to tissue death of the heart muscle ().It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart.
Unlike other causes of acute coronary syndromes, such as unstable angina, a myocardial infarction occurs when there is cell death, . The Lancet MEDICAL SCIENCE Can lifestyle changes reverse coronary heart disease?
