Abstract
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.
