It affects about 2% of people who are over 65 years of age. [1] Estimated rates were not known in most of the developing world as of 2014. [5] In those who have symptoms, without repair the chance of death at five years is about 50% and at 10 years is about 90%. [1] Aortic stenosis was first described by French physician Lazare Rivière in 1663 ...
Heart disease in women goes undetected prior to a major cardiac event in up to 60% of cases. [19] Among women who experience a heart attack, many do not have any prior chest pain. [ 19 ] Due to alterations in sensory pathways, diabetic and elderly individuals also may present without any chest pain and may have atypical symptoms similar to ...
Around 60% of patients will be angina-free 10 years after their operation. [33] Myocardial infarction is rare five years after a CABG, but its risk increases with time. [34] The risk of sudden death for CABG patients is low. [34] Quality of life is also high for at least five years, then can slowly start to decline. [35]
In women, the increase continues sharply until age 60 to 65 years. [ 34 ] Aging is also associated with changes in the mechanical and structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance and may subsequently lead to coronary artery disease.
In terms of the cause of aortic regurgitation, is often due to the aortic root dilation (annuloaortic ectasia), which is idiopathic in over 80% of cases, but otherwise may result from aging, syphilitic aortitis, osteogenesis imperfecta, aortic dissection, Behçet's disease, reactive arthritis and systemic hypertension.

Symptoms of the acute coronary syndromes are similar. [8] The cardinal symptom of critically decreased blood flow to the heart is chest pain, experienced as tightness, pressure, or burning. [9] Localization is most commonly around or over the chest and may radiate or be located to the arm, shoulder, neck, back, upper abdomen, or jaw. [9]
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and is driven by elevated levels of cholesterol in the blood. [9]
The incidence of stroke, including fatal stroke, is 1–2% per year. The surgical mortality of endarterectomy ranges from 1–2% to as much as 10%. Two large randomized clinical trials have demonstrated that carotid surgery done with a 30-day stroke and death risk of 3% or less will benefit asymptomatic people with ≥60% stenosis who are ...
