What this Trial Is About
In the field of cardiovascular medicine, there are two differing groups of patients that remain puzzling to clinicians: patients who are not expected to have coronary artery disease (CAD) yet are diagnosed with significant CAD; and those who are have multiple risk factors for CAD but do not have CAD. Bats exhibit unique phenotypes including long lifespans and likely reduced atherosclerosis. Prior work has identified multiple molecular mechanisms of suppressing the activation of inflammasomes, causally linked to atherosclerosis. The investigators hypothesize there are different molecular markers that confer protection or increased risk for CAD, some of which may be similar to bats. Thus, the aim of this study is to identify molecular markers that contribute to or are protective against acute coronary syndrome (ACS) through analyzing the genetics, peripheral blood and atherosclerotic samples from both extreme patient groups using single-cell RNA sequencing and multi-omics approach. In addition, novel anti-atherosclerotic mechanisms and factors from bat studies will be assessed in the human samples. Identification of novel targets that prevent or cause CAD has the potential to aid in the early identification of high-risk patients and development of new therapeutics to combat this growing epidemic. To conduct this study, patients who have undergone a coronary angiogram or a CT coronary angiogram that fall into the both extremes will be recruited and blood samples will be taken for the above analysis. These will be compared to a group of controls (low risk without disease and high risk with disease).
