Why does heart valve disease find the elderly?

Degenerative heart valve disease and calcific heart valve disease are relatively common diseases of the elderly, the former is mainly manifested by the thinning and lengthening of the structures supporting the valve, which in turn leads to a weakening of the support of the valve leaflets, resulting in incomplete closure; the latter refers to an originally normal valve or on top of a mild valve abnormality, with increasing age, the heart valve thickens, hardens, and deforms, resulting in valve stenosis or incomplete closure. Geriatric heart valve disease progresses very slowly and may not be asymptomatic for a significant period of time. However, when heart valve stenosis and insufficiency become severe, chest tightness on exertion, shortness of breath, lower extremity edema, and even inability to lie flat may occur. Heart valve disease may lead to heart failure, arrhythmia, syncope, angina and sudden death in the elderly. Because older adults often suffer from coronary heart disease, hypertension and other heart conditions, the symptoms that lead to valve disease are often masked from the attention of the patient. As the average human life expectancy is increasing, the incidence of age-related heart valve disease is increasing and rises with age. The etiology of the disease is not well understood. The main risk factors are age (risk increases 2-fold every 10 years with age), gender (aortic valve sclerosis occurs more frequently in men and the risk is 2-fold higher than in women), smoking (smoking increases the risk by 35%), hypertension (risk increases by 20% in those with a history of hypertension), and other risk factors including overweight, high blood lipids, and FK3. Early asymptomatic age-related heart valve disease does not require treatment and can be monitored dynamically; when symptoms appear, appropriate medication or surgery should be administered.
