In addition to its role in the removal of damaged and unneeded proteins, the ubiquitin-proteasome system (UPS) may play a key role in coronary artery disease (CAD). To investigate the expression of ubiquitin in monocytes and lymphocytes isolated from patients at different stages of CAD, 120 patients with CAD (40 with acute myocardial infarction [AMI], 40 with unstable angina pectoris [UAP] and 40 with stable angina pectoris [SAP]) were selected; 40 patients with normal coronary arteries served as controls. At both the mRNA and protein levels, ubiquitin expression was higher in patients with CAD than in controls, and patients with AMI had a much higher expression of ubiquitin (at both the mRNA and protein levels) than those with SAP and UAP. These data indicate that ubiquitin expression increased with increasing severity of CAD, suggesting that ubiquitin may play a critical role in the development and progression of CAD.

A 79-year-old female patient with multiple myeloma who had no prior cardiac disease history developed an acute myocardial infarction on day 5 after receiving bortezomib and dexamethasone (BD). After treatment of coronary stenoses by stents, she received another course of BD therapy and developed angina pectoris on day 5 after the therapy. Bortezomib's antitumor effect is due to the inhibition of proteasome activity. This inhibition may increase endothelial progenitor cell apoptosis and decrease endothelial nitric oxide synthase/nitric oxide (eNOS/NO), thus leading to coronary spasm. It is, therefore, important to carefully monitor patients being treated with bortezomib for the potential occurrence of ischemic heart disease.
