Nanotechnology has emerged as a transformative force in cardiac technology, offering unprecedented opportunities to improve the diagnosis, monitoring, and treatment of cardiovascular diseases. Manipulation of materials at the nanoscale enables exploitation of unique physicochemical properties, including high surface area, tunable surface chemistry, and enhanced biological interactions, facilitating the development of advanced tools that address limitations of conventional cardiac approaches. This chapter presents a comprehensive overview of nanotechnology-enabled innovations that are reshaping contemporary cardiovascular care through precision, personalization, and intelligent system integration. The chapter begins by outlining fundamental principles of nanoscale engineering, with emphasis on structure–function relationships that govern favorable interactions with blood components and cardiac tissues. It reviews recent advances in bioinspired materials, hybrid nanostructures, and functionalized nanoparticles, highlighting their applications in cardiac diagnostics, imaging, and therapy. Special attention is given to targeted and stimuli-responsive nanodrug delivery systems capable of releasing therapeutics in response to pathological cues such as inflammation, oxidative stress, or enzymatic activity, thereby enhancing therapeutic efficacy while minimizing systemic toxicity. Next-generation nanosensors are discussed as key enablers of real-time cardiac monitoring, capable of continuously assessing electrophysiological signals, biochemical biomarkers, and hemodynamic parameters. Their integration into wearable and implantable platforms supports remote monitoring, early disease detection, and personalized cardiology. Advances in nanoparticle-based contrast agents for cardiac imaging are also examined, demonstrating their ability to enable molecular-level visualization of inflammation, fibrosis, and vascular dysfunction prior to overt structural changes. Beyond diagnostics, nanotechnology has driven significant progress in cardiovascular implants and interventional devices. Nanoengineered stents, valves, and grafts exhibit improved endothelialization, reduced thrombogenicity, and enhanced durability, while nanofibrous scaffolds and targeted cell delivery systems show promise for cardiac tissue regeneration. Finally, the chapter addresses challenges related to nanotoxicology, safety, regulation, and clinical translation, and highlights emerging trends in precision cardiology, smart nano-integrated devices, artificial intelligence-assisted monitoring, and digital health convergence.
