Coronary artery disease is a pathological condition in which a coronary artery is narrowed or blocked, usually as a result of atherosclerosis. Stable angina, or 'angina pectoris', is the chest pain or discomfort that can result from the impaired blood flow through the blood vessels in the heart muscle, and usually occurs after exercise or stress.
In 1993, Lincoff and Topol claimed that the thrombolytic treatment of ST-segment elevation myocardial infarction was suboptimal in many patients and gave an ‘illusion of reperfusion’. In this Perspective article, the authors propose that a similar illusion of revascularization exists for contemporary percutaneous revascularization in patients with coronary artery disease and ischaemia, and identify how outcomes might be improved.
In the NOTION-3 trial, percutaneous coronary intervention reduced the occurrence of major adverse cardiac events compared with conservative treatment in patients who were undergoing transcatheter aortic valve implantation for severe aortic stenosis and who had stable coronary artery disease.
Findings from the ORBITA-COSMIC trial show that treatment of patients with stable coronary artery disease using a coronary sinus reducer improves angina symptoms but does not increase transmural myocardial perfusion.
In the ORBITA-2 trial, percutaneous coronary intervention was associated with a lower angina symptom score compared with a placebo procedure in patients with stable angina who were receiving minimal or no antianginal medication.
A machine learning model trained using clinical data from electronic health records generated a novel in silico quantitative score for coronary artery disease
Previous genome-wide association studies of coronary artery disease (CAD) have discovered multiple susceptibility loci but have largely failed to uncover causal genes. A new study identifies hundreds of likely causal genes underlying the genetic risk for CAD.
