Acute haemodynamic effects of felodipine in congestive heart failure

European Journal of Clinical Pharmacology
H EmanuelssonF Waagstein


The haemodynamic effects of felodipine 0.1 mg/kg p.o., a new arteriolar dilator, were studied in 7 patients with severe congestive heart failure of NYHA Class IV (Group A) and in 3 patients in Class II-III (Group B). In Group A, measurements were made before and 1 and 4 h after felodipine administration. There was a substantial fall in systemic arterial pressure, which was not associated with a compensatory tachycardia. In fact, there was a fall in heart rate from 92 to 82 beats/min 1 h after drug administration. The pulmonary capillary wedge pressure was reduced from 22 to 14 mm Hg and the cardiac index and stroke volume index rose significantly. Consequently, there was a marked reduction in systemic vascular resistance. In Group B measurements were performed at rest and during exercise before and 1 h after felodipine. The pulmonary wedge capillary pressure during exercise was lower than in the control situation. Coronary sinus flow was increased and there was a pronounced fall in coronary vascular resistance. The results would suggest that felodipine, by virtue of its ventricular unloading potency, might be a valuable drug in the treatment of congestive heart failure.

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.
