The kinetocardiogram during the isoproterenol test for the assessment of coronary heart disease

Cardiology
C Strozzi, G Cocco

Abstract

50 patients, 20 without heart disease and 30 with coronary heart disease (CHD), were studied by kinetocardiography (KCG), before and after administration of isoproterenol (initial dose 2 microgram/min, maximum dose 6 microgram/min). In the control subjects the KCG was unaffected by the drug. In contrast, in most of the patients with CHD isoproterenol induced the appearance or the increase of paradoxical systolic bulges, which are regarded as the expression of ventricular dyskinesia resulting from isoproterenol-induced transient regional ischemia. This test is recommended as a valuable noninvasive method for the diagnosis of ischemic ventricular dyskinesia.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
