Preclinical Cardiovascular Studies
Cardiovascular disease is a major cause of morbidity and mortality in our
aging population, and the number one killer around the globe, accounting for
more than 30 percent of deaths worldwide and 45 percent of deaths in the industrial
nations.
In the United States, cardiovascular disease is responsible for nearly one
million deaths annually. The direct cost of cardiovascular disease is estimated
at over $150 billion; and the cost in human suffering is immeasurable. Without
effective prevention
and intervention efforts, these numbers will continue to increase in coming
years.
Perry Scientific’s preclinical cardiovascular division offers a series
of animal models. These preclinical models may be used also for drug testing,
screening, and to evaluate the therapeutic effects of new compounds on cardiac
diseases.
Perry Scientific has focused on creating the most productive, respected and
innovative models for cardiac drug discovery, each designed to address unmet
clinical needs in the management of patients suffering from heart disorders
and its complications.
Brief Summary of Some of Perry Scientific’s
Preclinical Cardiovascular Animal Models
Atrial arrhythmias (fibrillation and flutter). Sustained atrial flutter
models are performed around an anatomical obstacle such as the tricuspid
valve or linear incision in the right atrium free wall. Sustained atrial
fibrillation models are determined following several weeks of fast atrial
stimulation (greater than 400 beats per minute).
Ventricular tachycardia models are developed either
in vivo or in vitro around a damaged tissue of the myocardium tissue
and by using an isolated Langendorff perfuse heart.
Myocardial infarction, ischemia or coronary artery disease models
are prepared by partially or totally obstructing the blood flows through
the coronary arteries (occlusion/reperfusion, tissue hypoxia and surgery
to mitigate tissue damage).
Heart failure models are many and variable and are
produced by methods such as damaging the aortic or the mitral valves.
Cardiomyopathy and pericarditis models are carefully
prepared by chronic application of proprietary powders.
Autonomic nervous system activation/deactivation models
are produced by either direct stimulation of the vagal nerves and stellate
ganglions, by neurotransmitters, blockers or by using the spectral analysis
methods.
Perry Scientific can offer these models in a variety of different animal
species such as dogs, pigs, rats, rabbits and mice. Perry Scientific
has the ability to test the invasive and non-invasive cardiac resuscitation
devices in different animal models. All studies are performed at Perry
Scientific’s state-of-the-art, AAALAC-accredited vivarium located in San Diego.
For all our projects, we assemble project teams across department lines
and, if required for their specific expertise, with other consultants.
Perry Scientific serves the biotech industry by supplying preclinical
services such as new drug testing and evaluation, contract animal housing
and services, preclinical model development, management of research studies
and statistical and data analysis.
