Iron is fundamental for life-essential processes. However, it can also cause oxidative damage, which is thought to trigger numerous pathologies, including cardiovascular diseases. The role of iron in the pathogenesis of atherosclerosis is still not completely understood. Macrophages are both key players in the handling of iron throughout the body and in the onset, progression and destabilization of atherosclerotic plaques. Iron itself might impact atherosclerosis through its effects on macrophages. However, while targeting iron metabolism within macrophages may have some beneficial effects on preventing atherosclerotic plaque progression there may also be negative consequences. Thus, the prevailing view of iron being capable of accelerating the progression of coronary disease through lipid peroxidation may not fully take into account the multi-faceted role of iron in pathogenesis of atherosclerosis. In this review, we will summarize the current understanding of iron metabolism in the context of the complex interplay between iron, inflammation, and atherosclerosis.

Implantation of drug-eluting stents (DES) is the dominant treatment strategy for patients with symptomatic coronary artery disease. However, the first-generation DES had substantial drawbacks, including delayed healing, local hypersensitivity reactions and neoatherosclerosis, which all led to a steady increase in major adverse cardiovascular events over time. Subsequently, newer-generation DES were introduced with thinner struts, different scaffold designs (to improve deliverability while maintaining radial strength), different durable and biodegradable polymers – and in some cases no polymer (to improve vascular biocompatibility) – and new antiproliferative drug types and doses. Currently, >30 different DES are commercially available in Europe, with fewer available in the USA but with many new entrants coming onto the US market in the next few years. Never before have cardiologists been faced with so many choices of stent, each with its own unique design. In this Review, we detail preclinical and pathology studies for each stent design, examining thromboresistance, speed of neointimal coverage and completeness of healing, including endothelialization. We conclude by discussing how these design characteristics might affect the potential for shortening the minimum duration of dual antiplatelet therapy needed after coronary intervention.
