The Role of Pyroptosis in Coronary Heart Disease

The incidence and mortality of cardiovascular diseases, of which coronary heart disease (CHD) is a significant cardiovascular burden, are on the rise. Pyroptosis as an incipient programmed cell death mediated by inflammasomes can sense cytoplasmic contamination or interference and is typically marked by intracellular swelling, plasma membrane blistering and intense inflammatory cytokine release. As research on pyroptosis continues to progress, there is mounting evidence that pyroptosis is a vital participant in the pathophysiological basis of CHD. Atherosclerosis is the major pathophysiological basis of CHD and involves pyroptosis of endothelial cells, macrophages, vascular smooth muscle cells, and other immune cells, often in association with the release of pro-inflammatory factors. When cardiomyocytes are damaged, it will eventually lead to heart failure. Previous studies have covered that pyroptosis plays a critical role in CHD. In this review, we describe the properties of pyroptosis, summarize its contribution and related targets to diseases involving angina pectoris, myocardial infarction, myocardial ischemia in perfusion injury and heart failure, and highlight potential drugs for different heart diseases.
