Coronary artery bypass graft markers: history, usage, and effects

AbstractCoronary artery bypass grafting (CABG) is one of the most common procedures in the United States as many Americans suffer from coronary heart disease and undergo CABG each year. While CABG has been performed for decades, questions remain regarding the benefits graft marker placement provides for patient therapy and outcomes. Markers at the proximal graft anastomosis aim to improve the efficiency and reduce the risks of subsequent, post-coronary artery bypass grafting coronary angiography by decreasing fluoroscopy time and contrast volume used. Graft markers have been shown to reduce fluoroscopy time and contrast volume, but concerns exist regarding their potentially negative impact on patient outcomes by increasing procedural time and possibly affecting graft patency. The relationship between graft markers and graft patency has not been studied in depth, and there is little evidence to show that graft patency is determined by graft marker placement. Because of the potential benefits to patients and the limited risks, it is important to continue studying graft marker usage and their effects on long-term outcomes.

A previously healthy, well-appearing 42-year-old female living in a modern, high-rise apartment in downtown Los Angeles calls 9-1-1 at 5:30 am complaining of worsening of a burning, epigastric pain she had been experiencing for the last three days. She reports associated nausea and non-bloody, non-bilious vomiting, and that she couldn’t manage to get comfortable in bed until she finally decided to call for help at daybreak. During her 9-1-1 call, she reports “pain, like heartburn, that just woke me up again and I had to throw up, … and then I was sweating so much.” Using the Los Angeles Tiered Disp...

This review tries to answer the following 15 questions: Is atherosclerosis a systemic or a regional disease? Is atherosclerosis in any particular region focal or diffuse? What is the quantity of atherosclerotic plaques in endarterectomy specimens of the right coronary artery in patients undergoing coronary artery bypass grafting (CABG) compared to that in the right coronary artery in patients with fatal coronary artery disease? How do the units used for measuring arterial narrowing by angiography compare to the units used for measuring arterial narrowing at necropsy? What do atherosclerotic plaques consist of in coronary a...

AbstractPurpose of the ReviewCoronary artery disease is a major cause of mortality and morbidity in the world, and PCI and CABG account for over a million procedures performed annually in the USA. The goal of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is to achieve complete revascularization (CR) if at all possible. However, restenosis and stent thrombosis (ST) remain the Achilles heel of contemporary PCI with restenosis rates between 10 and 30% with bare metal stents to 5 –15% after drug-eluting stents and ST rates of around 0.8 vs 1.2%, respectively. Routine angiography after...

Conclusions: Our study suggested that incident CHD was positively associated with plasma levels of titanium and arsenic, and inversely associated with selenium. Additional research is needed to confirm these findings in other populations. https://doi.org/10.1289/EHP1521 Received: 22 December 2016 Revised: 17 September 2017 Accepted: 19 September 2017 Published: 19 October 2017 Address correspondence to T.

CONCLUSIONS: This updated Cochrane Review found that for people with CHD, there was no evidence that psychological treatments had an effect on total mortality, the risk of revascularisation procedures, or on the rate of non-fatal MI, although the rate of cardiac mortality was reduced and psychological symptoms (depression, anxiety, or stress) were alleviated; however, the GRADE assessments suggest considerable uncertainty surrounding these effects. Considerable uncertainty also remains regarding the people who would benefit most from treatment (i.e. people with or without psychological disorders at baseline) and the specif...

AbstractLipoprotein  (a) (Lp (a)) is one risk factor for the development of cardiovascular diseases. Several studies have shown that Lp (a) hyperlipoproteinaemia has a particular influence on the development of coronary heart disease (CHD). A retrospective single-centre observation study was performed to evaluate the effectiveness of lipid apheresis on the basis of consecutively performed percutaneous coronary interventions (PCI) in patients with high Lp (a) values and angiographically documented CHD.In 23  pts (male 18, age 60.04 ± 0.58 years) with angiographicall...

Prognostic value of angiographic follow-up in patients undergoing percutaneous coronary interventions (PCIs) of the left main coronary artery (LMCA) still remains uncertain. The aim of the study was to compare clinical characteristics, mortality, and major cardiovascular events in patients with versus without angiographic follow-up after PCI of the LMCA as well as to identify independent risk factors for death after PCI of the LMCA. Study population consisted of 217 patients of 290 consecutive participants who underwent PCI of the LMCA and subsequently were divided into 2 groups: angiographic follow-up group (angio FU grou...
