title: Ageing and the cardiovascular system.
abstract: Heart disease is the most common cause of death in elderly people. Cardiovascular aging is a continuous and irreversible process. It has a decline rate that varies among individuals and can be modulated by three conceptually different influences, namely, physiological changes due to the passage of time, adaptive sequeles of previous diseases or surgery in younger life, and influence of the individual lifestyle or their own cardiovascular risk factors. The main practical consequences of aging processes are a progressive change in the morphological, functional, and semiological characteristics of the cardiovascular system and an increase in the number of age-related cardiovascular disorders. The main morphological cardiovascular changes with aging happen in the structure of cardiac tissue and chambers, in the conduction system, and in the coronary arteries. But the cardiac function at rest in healthy elderly persons is adequate to meet the body's need. A normal or almost normal cardiac output in the elderly is to be maintained by increasing the stroke volume and the ejection fraction due to an augmented cardiac filling (preload). Atypical clinical pictures are very common in elderly patients with cardiovascular disease. For example, non-cardiac symptoms are the often presenting features. Concerning the treatment of cardiovascular diseases in the elderly, the clinician needs to consider age-related factors as multimorbidity and disabilities, the possible side effects and/or interactions due to pharmacodynamic or/and pharmacocinetic changes. And he has to take into account the social and financial situation of his patient.
