Abstract
Aging is one of the most important cardiovascular risk factors. Age-related morphologic changes in large resistance vessels include an intima-media-thickening and increased deposition of matrix substance, ultimately leading to a reduced compliance and an increased stiffness of the vessels. Aging of the heart is mainly characterized by an increase of the left ventricular mass in relation to the chamber volume and a decrease of diastolic function. There is some controversy in regard to the question if these changes in the vessel wall are the consequence of aging or if a decrease in physical activity is a major contributor of this process. With age the cardiovascular profile is changing. Whereas smoking is less prominent, arterial hypertension and diabetes mellitus are more often encountered. Primary and secondary prevention through cardiovascular risk factor management is also very important in the aging population due to the increased risk of acute vascular complications with age. Preventive measures have to include life style factor interventions as well as optimized drug therapy. There is no scientific evidence that vascular aging can be prevented by administration of supplements such as antioxidant vitamins. Aspirin is effective for cardiovascular prevention up to a higher age. Betablockers and ACE-inhibitors are generally underused in older patients after myocardial infarctions. Statins are effective in reducing cardiovascular complications up to an age of 80 years. Myocardial infarction in elderly patients is often characterized by atypical symptoms and may be even silent. Interventional therapy in elderly patients is as successful as in younger patients but has an increased complication rate. Ambulatory cardiac rehabilitation in elderly patients leads to significant improvements of physical capacity, well-being and quality of life and may help to prevent social isolation.
