The ratio of M1/M2 macrophages in epicardial adipose tissue of CAD patients is changed compared with that in non-CAD patients. Human coronary atherosclerosis is associated with macrophage polarization in epicardial adipose tissue.

These data may indicate that PPAR-γ agonist become the way for preventing or delaying aortic aneurysm progression in patients. More studies will be needed to clarify this drug effects in detail.

Two adult patients with previous transient cerebral ischemic attacks (TIAs) or chest oppression were referred for further investigation. A swaying pedicled tumor was detected in the left atrium of the former patient and in the left coronary cusp of the latter by echocardiography. The TIA, or angina-like attack, was anticipated to be caused by thromboembolism of the tumor. Both patients underwent tumor extirpation. The histological findings demonstrated that both tumors were benign papillary fibroelastoma limited to the endocardium/endothelium layer. In conclusion, early surgical resection of a cardiac papillary fibroelastoma should be performed.
