Ultrasound and a blood test can increase survival after myocardial infarction

25.01.2011
Two relatively simple methods, an ultrasound investigation and a blood test to measure the level of a substance known as BNP, can predict survival and future heart failure following acute coronary syndromes. This is the conclusion of a thesis presented at the University of Gothenburg, Sweden.

Acute coronary syndromes, such as myocardial infarction and unstable angina, are among the most common causes of emergency medical care and death in Sweden for both women and men.

"The ability to predict the future course of the syndrome in a patient may improve the possibility of providing extra preventative treatment for those with the highest risks. Or, and this may be more important, the possibility of following these patients with more frequent check ups in order to detect early whether the patient's health is deteriorating", says biomedical scientist, Anita Persson.

The study on which the thesis is based showed that elevated levels of B-type natriuretic peptide (BNP) in the blood were associated not only with an impaired ability of the heart to pump blood, but also with the risk of rehospitalisation due to heart failure following acute coronary syndromes, and premature death. One noteworthy finding was that the correlation between high BNP and future risk was present also for those patients who did not show signs of heart failure during the first acute episode.

The other method that Anita Persson has evaluated is the use of ultrasound, in a technique known as "Doppler echocardiography", to assess leakage at one of the valves in the heart. It proved to be the case that the ultrasound investigation can predict not only increased mortality but also increased rehospitalisation due to heart failure.

She found, by comparing many different properties of the function of the heart determined by Doppler echocardiography, that an increased volume of the left ventricle and increased pressure during the filling phase of the heart action or increased stiffness of the ventricle were associated with a poorer prognosis and an increased risk of complications.

The study is based on a large group of patients with acute coronary syndromes who received care between September 1995 and March 2001 in the Coronary Care Unit at Sahlgrenska University Hospital. "Including the echocardiography variables on their own or in combination with the level of BNP in the risk assessment can be a relatively simple means of identifying high-risk patients and those who have the best preconditions for avoiding

complications", says Anita Persson.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
