Aortocoronary vein bypass in patients with angina pectoris

Acta Medica Scandinavica

Abstract

In the 3-year period from May 1971 to April 1974, 90 patients had aortocoronary bypass for angina pectoris at Ulleval Hospital. One patient died shortly after the operation (operative mortality 1.1%). There were no further deaths in the observation period. Clinical improvement was seen in 93% of the patients, early shunt patency in 92%. The study suggests that patients with isolated affection of the right coronary artery should not have bypass, because these patients 1) had less severe symptoms, 2) had better preserved left ventricular function, and 3) seemed to have a smaller chance of benefiting from the operation than the other patients. Multiple shunts gave good clinical results and carried no higher surgical risk than did single shunts. Good clinical results were seen also in patients with occluded shunts provided they had at least one patent shunt too. Graft occlusion occurred early and was associated with low graft flow as measured intraoperatively. Graft occlusion was not usually followed by demonstrable myocardial necrosis. In view of the small operative risk and the high score of symptom relief it is concluded that all patients with angina pectoris that does not readily respond to medical treatment, should be consider...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Incretins

Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.
