Despite the ongoing development in invasive cardiovascular interventions and pharmacological therapies over the past 25 years, cardiovascular diseases (CVD) continue to account for 31% of all deaths worldwide. This amounts to 17.9 million deaths per year, a number that is expected to grow to more than 23.6 million by 2030, according to WHO estimates. According to the European Cardiovascular Disease Statistics 2017 (Wilkins et al., 2017), CVD caused 3.9 million deaths in Europe alone. As reported by the 2019 Heart Disease and Stroke Statistics of the American Heart Association (Benjamin et al., 2019), every 40 s, an American will suffer from a myocardial infarction (MI).In the recent years, effective medicines allowed to better control blood cholesterol levels, to lower blood pressure and, finally, to reduce inflammation, which contributed to improved management of patients with CVD. However, the first symptom of CVD in more than 50% cases is acute cardiovascular event or sudden cardiac death. This background calls for more reliable risk assessment allowing earlier disease detection and for improved therapeutic approaches.Atherosclerosis and arterial thrombosis, the underlying causes of cardiovascular morality, can manifest as acute coronary syndromes, stroke or peripheral arterial disease. Drug delivery systems, which enable for example targeted application of medicines should have an enormous impact for the affected patients, as personalized tools to support the physicians in both the choice and the administration of recommended therapies. Among the potential therapeutic targets of novel drug delivery systems and biomaterial implants are vulnerable atherosclerotic plaques, ischemic myocardium, cerebro-, retino-, and renovascular disorders, but also thrombosis. Besides, cardiovascular stents, prostheses and patches can serve as tools for local drug delivery to enhance vascular healing and prevent neoatherosclerosis. The road from the ambitious experimental ideas to the clinical routine remains difficult, however. There are several Grand Challenges that must be addressed to overcome the hurdles for the development of drug delivery systems that will improve the outcomes of patients with CVD. Besides the biggest obstacle, which is the clinical safety and translation, also innovation, personalization and drug delivery on-demand represent major challenges. These challenges are discussed in detail below.
