The number of elderly patients admitted to cardiac intensive care units (CICU) is significantly increasing. Nowadays, novel diagnostic and therapeutic tools allow to treat the vast majority of cardiac acute diseases, nonetheless care of elderly patients requires a careful clinical evaluation. A favorable proportion of cost-effectiveness is warranted, aimed at avoiding futile procedures or treatments. On the other hand, the availability of minimally invasive procedures carries forward old limits to treatments in elderly patients in CICU. It appears evident that age cannot per se represent a limit in the care of elderly people. The present review gives insights in the management of the most common cardiovascular disease settings in elderly patients in the CICUs, thus providing important tools in complex decision-making.
