Changes in coronary artery disease five years after coronary bypass surgery

Abstract

Seventy-nine patients underwent repeat coronary angiographies five years after coronary bypass surgery. Ninety-eight of 122 inserted grafts (80%) were patent. Significant coronary obstruction (greater than 50% reduction of luminal diameter) developed in 43/79 patients (54%) and was associated with a longer duration of angina before surgery and a lower diastolic blood pressure at the five-year follow-up, but significantly related to such factors as age, sex, type of angina, previous myocardial infarction, hypertension, hyperlipaemia, diabetes or smoking. The total number of significant obstructions increased from 230 to 308 (34%). Progression of pre-existing changes to occlusion was common and the number of occlusions increased 95% in non-grafted arteries compared with 48% in grafted arteries until the five-year evaluation. Fifty-seven of 81 new significant obstructions (70%) were found in non-grafted coronary arteries. The proximal part of the right coronary artery was most commonly affected with 19/57 (33%) of these new obstructions. A significant stenosis regressed in three patients. At the five-year follow up, 74/79 patients (94%) had less symptoms than before operation and 27/79 patients (34%) were asymptomatic. Nine patien...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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
