heart disease

heart disease teriminin İngilizce İngilizce sözlükte anlamı: disease which affects the heart's ability to function; A structural or functional abnormality of the heart, or of the blood vessels supplying the heart, that impairs its normal functioning. an illness which prevents your heart from working normally. Any disorder of the heart. Examples include coronary heart disease, congenital heart disease, and pulmonary heart disease, as well as rheumatic heart disease (see rheumatic fever), hypertension, inflammation of the heart muscle (myocarditis) or of its inner or outer membrane (endocarditis, pericarditis), and heart valve disease. Abnormalities of the heart's natural pacemaker or of the nerves that conduct its impulses cause arrhythmias. Some connective tissue diseases (notably systemic lupus erythematosus, rheumatoid arthritis, and scleroderma) can affect the heart. Heart failure may result from many of these disorders; a disease of the heart; an abnormal condition of the heart; takes many forms Usually, heart disese occurs due to inadequate blood flow to the hear muscle This occurs when the arteries that supply the heart muscle (the coronary arteries) become partially or completely blocked Obese people are at increased risk of heart disease due to their higher rates of hypercholesterolemia, diabetes and hypertension; Heart disease refers to any disease or condition of the heart, including coronary heart disease, heart failure, hypertensive heart disease, congenital heart disease, disorders of the heart valves, infections of the heart, cardiomyopathy, conduction disorders, and rhythm disorders; coronary disease; {i} cardiopathy
coronary heart disease: Any disease caused by the accumulation of fatty deposits in the coronary arteries that supply blood to the myocardium
congenital heart disease: Deformity of the heart. Examples include septal defect (opening in the septum between the sides of the heart), atresia (absence) or stenosis (narrowing) of one or more valves, tetralogy of Fallot (with four components: ventricular septal defect, pulmonary valve stenosis, right ventricular enlargement, and positioning of the aorta so that it receives blood from both ventricles), and transposition of the great vessels (so the pulmonary and systemic circulations each receive blood from the wrong side of the heart). Such defects can prevent enough oxygen from reaching the tissues, so the skin has a bluish cast. Many are fatal if not corrected surgically soon after birth or, rarely, before birth, if detected prenatally. Abnormalities of the large vessels are usually less serious (see aorta, coarctation of; ductus arteriosus)
coronary heart disease: or ischemic heart disease Progressive reduction of blood supply to the heart muscle due to narrowing or blocking of a coronary artery (see atherosclerosis). Short-term oxygen deprivation can cause angina pectoris. Long-term, severe oxygen depletion causes a heart attack. Coronary bypass or angioplasty is needed if medication and diet do not control the disease
pulmonary heart disease: or cor pulmonale Enlargement and eventual failure of the right ventricle of the heart due to disorders of the lungs or their blood vessels or chest wall abnormalities. Chronic disease is most often caused by chronic bronchitis or emphysema. Symptoms include chronic cough, trouble in breathing after exertion, wheezing, weakness, leg edema, right upper abdominal pain, and neck vein distension. Pressure in the pulmonary artery rises and the right ventricle enlarges in response, leading, if uncorrected, to heart failure. Treatment includes a respirator, low-sodium diet, diuretics, digitalis, and antibiotics for respiratory infection. Acute disease due to pulmonary embolism is often treated by removal of the blockage
rheumatic heart disease: Permanent damage to the valves of the heart caused especially by repeated attacks of rheumatic fever
rheumatic heart disease: heart disease caused by recurrent episodes of rheumatic fever; characterized by changes in the myocardium or scarring of the heart valves that reduce the power of the heart to pump blood
valvular heart disease: heart disease caused by stenosis of the cardiac valves and obstructed blood flow or caused by degeneration and blood regurgitation
