Common cardiovascular conditions Rheumatic heart disease Rheumatic heart disease is caused by one or more attacks of rheumatic fever, which then do damage to the heart, particularly the heart valves. Rheumatic fever usually occurs in childhood, and may follow a streptococcal infection. In some cases, the infection affects the heart and may result in scarring the valves, weakening the heart muscle, or damaging the sac enclosing the heart. The valves are sometimes scarred so they do not open and close normally. Hypertensive heart disease High blood pressure of unknown origin (primary hypertension) or caused by (secondary hypertension) certain specific diseases or infections, such as tumor in the adrenal glands, damage to or disease of the kidneys or their blood vessels. High blood pressure may overburden the heart and blood vessels and cause disease. Ischemic heart disease Heart ailments caused by narrowing of the coronary arteries and therefore a decreased blood supply to the heart. Cerebrovascular disease Disease pertaining to the blood vessels in the brain. A cerebrovascular accident or stroke is the result of an impeded blood supply to some part of the brain. Inflammatory heart disease Inflammation of the heart muscle (myocarditis), the membrane sac (pericarditis) which surround the heart, the inner lining of the heart (endocarditis) or the myocardium (heart muscle). Inflammation may be caused by known toxic or infectious agents or by an unknown origin.
