Background—Off-pump coronary artery bypass grafting compared with coronary revascularization with cardiopulmonary bypass seems safe and results in about the same outcome in low-risk patients. Observational studies indicate that off-pump surgery may provide more benefit in high-risk patients. Our objective was to compare 30-day outcomes in high-risk patients randomized to coronary artery bypass ...

BACKGROUND We hypothesize that implantation of left ventricular assist device through off-pump technique is feasible and has a comparable result to implantation on cardiopulmonary bypass and could improve one-year survival. METHODS This retrospective, observational, single-center study was conducted on 29 consecutive patients at our institution who underwent off-pump left ventricular assist d...

There are controversies about the possible benefits of off pump coronary artery bypass grafting (OPCABG) compared to on-pump coronary artery bypass grafting (ONCABG). For a better perspective on this important issue, we performed a meta-analysis of randomized controlled trials, comparing the two techniques. The objective of this study was to verify which technique applied in Coronary Artery Byp...

background & purpose: air pollution has been known as one of the most effective factors on cardiovascular, pulmonary and infectious diseases. this study aims to determine the relation between mortality rate and air pollution in mashhad during 2007-2009. materials & methods: data of air pollution, mortality rate and geographic factors were collected during 2007-2009 and analyzed. mortality rate,...

OBJECTIVE Off-pump coronary artery bypass grafting may result in fewer myocardial and vascular complications than on-pump. Although differences in aortic manipulations likely play a role, the systemic responses of endothelial progenitor cells to both types of operations have not been examined. We sought to examine endothelial progenitor cell characteristics after off-pump versus on-pump coronar...

backgroundseveral studies have examined the relationship between human development index (hdi) and various health outcomes. the aim of this study was to investigate the relationship between hdi, and infant mortality rate, mortality rate of children under one year and under 5 years, maternal mortality rate, and total fertility rate.materials and methodsin this ecologic study, data on hdi, total ...

BACKGROUND This prospective non-randomized clinical study was done to compare Off-pump and On-pump myocardial revascularization by Troponin I release in patients undergoing first elective coronary artery bypass graft used to evaluate myocardial injury. METHODS One hundred an twenty patients were non-randomly assigned to a Off-pump or On-pump myocardial revascularization group. Cardiac Troponi...
