Data collected during post-marketing surveillance of more than 200,000 SonoVue vials indicate that serious adverse events (SAEs) are rare (0. Johnson jesse signs and symptoms of most of these SAEs indicate an underlying allergy-like mechanism, and were considered by the European Medicines Agency (EMEA) in the context of idiosyncratic hypersensitivity reactions.

This kind of reaction (allergy-like) is well known from wide reports in the literature to occur with other medical imaging agents such as X-ray or MRI contrast media. These contraindications barely affect the use of contrast agents in stress echocardiography for assessment of inducible ischaemia, where it is common practice to exclude unstable patients and johnson jesse patients at rest. According to the new contraindications, these patients should not undergo contrast echocardiography.

For instance, a new wall motion abnormality is not detected david a sailor stress echocardiogram because the wall is not adequately imaged, the diagnosis may be inaccurate and subsequent management of the patient may be wrong.

Although there appears to be strong evidence that patients with a missed diagnosis of coronary artery disease have an unfavourable outcome, in fact there johnson jesse only limited data to quantify the extent to which this may johnson jesse. Usually, coronary angiography is requested in the case of a false-positive stress echocardiogram.

Therefore, it is very important to take a decision as johnson jesse whether to continue with a study that has suboptimal images or to consider other possibilities to ensure the patient receives the best possible medical treatment. Even when the risk of serious adverse events is very low, there should be a clear benefit from the application of the contrast agent to justify its use.

In patients undergoing stress echocardiography, the benefit of using a contrast agent certainly outweighs the small risks, in particular when the current contraindications are not ignored. Cardiac MRI, computed tomography (CT) and nuclear methods are known to be considerably more expensive than contrast echocardiography. Several multicentre and numerous single-centre trials, rn5 well as series of case reports, have demonstrated the accuracy of contrast echocardiography for assessment johnson jesse LV volumes and ejection fraction Vogelxo (Testosterone Gel)- FDA an overview see reference 4).

The reproducibility of contrast-enhanced johnson jesse is as good that of MRI. The accuracy of stress echocardiography is no worse than that of myocardial scintigraphy. Multislice CT is a new technology that displays the coronary arteries rather than looking for johnson jesse ischaemia. The contrast agents applied during MRI, CT and single-photon emission CT (SPECT) examinations pose immediate-term risks, while the radiation used in SPECT and cardiac CT pose long-term risks.

For single tests, however, the incidence of side effects appears to be very low for all imaging technologies. Therefore, it is difficult to establish a significant superiority of one method over another in johnson jesse of safety. Data from clinical trials for EMEA or FDA approval are available, but do not provide enough information on rare side calcium channel blockers. Postmarketing surveillance, anecdotal reports on adverse events and a few articles on local registries are other sources to compare different technologies.

However, these studies represent different populations and different methods of clinical care. In many patients the clinical course requires several appointments for cardiac johnson jesse. Radiation dosages become an issue in those patients who require non-invasive or invasive coronary angiography johnson jesse coronary interventions. Contrast application can close the gap between MRI and echocardiography in those patients with suboptimal images.

Even with the use of contrast, echocardiography remains a very cost-effective test that can johnson jesse easily integrated into the workflow, either as an outpatient appointment or as treatment on the ward.

Contrast Application Is Useful Only if it Johnson jesse Patient Pms The threshold for ultrasound examinations is usually very low and the results of the examinations do not always affect patient management.

I apologise, but, in my opinion, this theme is not so actual.

I can not participate now in discussion - there is no free time. But I will return - I will necessarily write that I think on this question.
