Application of Single-Cell Genomics in Cardiovascular Research

Cardiovascular diseases (CVDs) are the leading cause of death in the global world. The emergence of single-cell technologies has greatly facilitated the research on CVDs. Currently, those single-cell technologies have been widely applied in atherosclerosis, myocardial infarction, cardiac ischemia–reperfusion injury, arrhythmia, hypertrophy cardiomyopathy, and heart failure, which are extremely helpful in elucidating the underlying mechanisms of CVDs from physiological and pathological perspectives at DNA, RNA, protein, post-transcriptional, post-translational, and metabolite levels. In this review, we would like to briefly introduce the current single-cell technologies, and will focus on the utilization of single-cell genomics in various heart diseases. Single-cell technologies have great potential in exploration of CVDs, and widespread application of single-cell genomics will promote the understanding and therapeutic treatments for CVDs.
