The morbidity of coronary heart disease (CHD) is high, and the prognosis is unfavorable. Fibrinogen is both coagulation and inflammation factor, which has important influence on the occurrence and development of CHD. Previous studies reported that fibrinogen had relevance with traditional risk factors of CHD such as hypertension, diabetes and subclinical diseases such as left ventricular hypertrophy. The incidence of CHD increases with the fibrinogen level increasing. The fibrinogen level is higher in patients with CHD than that in healthy people. The coronary stenosis degree is heavier and the lesion is wider in patients with hyperfibrinogenemia. But the effects of fibrinogen on the secondary prevention of CHD is controversial. This paper summarized research progress based on the new understanding to fibrinogen on CHD recently.
Objective To search and review the best clinical evidence to compare the clinical therapeutic effects and safety between TAVR and SAVR, thereby guiding its clinical use and providing references of treatments for such patients. Methods EMbase (1974～2016), MEDLINE (1996～2016) and The Cochrane Library (Issue 5, 2016) were systematically retrieved to collect randomized control trials, case-control studies and meta-analyses. Then, we assessed the quality of all the evidences to develop treatments based on those evidences and the situations of such patients. Results We identified 21 articles, including 2 articles of meta-analysis. With regard to the mortality and incidence of cardiovascular events, TAVR was not worse than SAVR. In addition, TAVR was more dominant than SAVR for patients who combined more basic diseases. Conclusion TAVR is one of the effective treatments for most patients with severe AS after sufficient assessment.
