Percutaneous coronary intervention in the elderly: current updates and trends

Abstract

Ischemic heart disease is the leading cause of death with acute coronary syndrome accounting for more than 30% of causes of mortality in the elderly population. The rate of growth of the older segment of the population has increased exponentially and will become more pronounced in the future. Historically, there has been a paucity of clinical trials investigating the challenges and outcomes of more invasive treatment strategies such as percutaneous coronary intervention (PCI) for that very segment of the population. However, the safety, efficacy, and outcomes of PCI in the older population have started to receive more attention, leading to some changes in their trends. There are several factors that make interventional cardiologists more resistant to direct the elderly to PCI. Most of these challenging factors, such as the complexity of coronary lesions, frailty, hematological and vascular changes, are discussed in this review. In addition. more advanced technologies have been introduced to PCI platform such as second- and third-generations stents, several alternative approaches have been adopted like transradial approach and the usage of bivalirudin instead of heparin and GP IIb/IIIa inhibitor, and several imaging modalities have been optimized to assess patients’ outcome and prognosis more accurately. Several recent studies have shown better results when these strategies are adopted. The most recent recommendations regarding performing PCI in the elderly are also discussed in this review.
