The effects of orally administered atenolol on the coronary hemodynamics and prostaglandin metabolism in angina pectoris patients

A KuritaK Mizuno


The effects of oral atenolol on coronary hemodynamics and prostaglandin metabolism have been investigated in 8 chronic stable angina pectoris patients who underwent the supine bicycle ergometer. At rest, atenolol taken orally reduced the pressure-rate product significantly (P < 0.05) but did not significantly affect the coronary sinus blood flow or the coronary sinus pressure. During exercise, atenolol also reduced the pressure-rate product significantly (P < 0.05) but did not significantly affect the coronary sinus blood flow, the coronary sinus pressure, or the coronary vascular resistance. Atenolol also did not significantly affect the thromboxane B2/6-keto prostaglandin F1 alpha ratio in the arterial blood before and after exercise but did reduce this ratio in the coronary sinus blood by 15% from 1.9 +/- 1.1 to 1.5 +/- 0.46 (P < 0.10) after exercise. These results indicate that atenolol taken orally does not significantly depress the coronary hemodynamics. However, the effects of atenolol on the prostaglandin metabolism could not be clearly determined.

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.

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.

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.
