Stress echocardiography is a valuable clinical tool for diagnostics and
to functionally assess coronary artery disease.
Various forms of cardiovascular stress (exercise test, pharmacological
stress
echocardiography, atrial pacing) are used at Stress Echocardiography.
According to the recent guidelines of the American College of
Cardiology/American
Heart Association pharmacological stress echocardiography with either
dobutamine
or dipyridamole is a class 1 indication (of documented effectiveness
and usefulness)
for the diagnosis of coronary artery disease and for the prognostic
stratification
of patients with known coronary artery disease.
The American Society of Echocardiography has also recommended with
either
dobutamine or dipyridamole as the preferred modality in patients who
cannot exercise.
Dobutamine echocardiography has also been used safely in the assessment
of patient
status after myocardial infarction and in the differentiation of viable
myocardium
from myocardial scar in patients being considered for coronary
revascularization.
Viable myocardium exhibits a visible contractile reserve in response to
low-dose
dobutamine infusion. At higher-dose dobutamine infusion, the inotropic
stimulation
creates an oxygen supply/demand mismatch rendering the myocardium
ischemic.
This biphasic response, with regional augmentation of function at
low-dose dobutamine
followed by deterioration of regional function at high-dose dobutamine,
is highly
predictive of functional recovery after revascularization.
We have begun to work with the creation of such software, which should
add the
software for Echocardiography used at work on Ultrasound Diagnostic
Systems
of the various manufacturers. Low cost of the programs, easy use and
the
additional features of the analysis of researches will make STRESS BROWSER,
TEE BROWSER and TTE BROWSER
effective assistants for any doctor who is carrying out
Echocardiography.
Electrocardiography and 2D echocardiography are mainly used as methods
of monitoring
work of heart at Stress Echocardiography. Modern Ultrasound Diagnostic
Systems with
digital architecture and special software are used at Stress
Echocardiography.
For successful functioning of the program it is enough to have a
computer low-end: Pentium 233 ЬЬе or higher, 32 Mb RAM, the
videoadapter 8 Mb, 20 Mb free on HDD, operational systems WINDOWS 98,
98SE, ME, NT4, WIN2000, XP. Other additional equipment is not required.
The software is delivered on CD ROM, also containing an electronic
Interactive
Help System and the user's manual. Delivery is carried out by
international mail
after the money order of the contractual sum to the account of the firm
- supplier,
which is the guarantor. More detailed information about conditions of
delivery it
is possible to find out by e-mail.
On the following page the
slides giving representations
about opportunities and features of software functioning are submitted.
You may download the Trial
Version Setup Program (v. 1.0).
More detailed information about software and its demonstration version
can be
received on Russian-language
pages
of the site. There it is possible to exchange opinions on the offered
software
and to discuss professional topics.
You can ask any questions by
e-mail. It is desirable in English or Russian.
