LEFT VENTRICULAR TWIST AND LEFT VENTRICULAR UNTWIST RATE – GOOD
PARAMETERS TO MONITOR RECOVERY OF GLOBAL LEFT VENTRICULAR
FUNCTION AFTER TREATMENT
New Data From the World Congress of Cardiology
BEIJING, 18 JUNE 2010. Left ventricular twist (LVT) and left ventricular untwist rates (LVUR), measures of
myocardial deformation during contraction and relaxation, might be good parameters to monitor the recovery
of global left ventricular (LV) function after treatment, according to new data presented today at the World
Congress of Cardiology (WCC) Scientific Sessions in Beijing, China.
Results of a new study conducted in 88 patients demonstrated that left ventricular strain (LVS), left
ventricular strain rates (LVSR), LVT and LVUR are reduced in acute myocardial infarction (AMI) patients
early after reperfusion and recover incompletely upon follow-up.
“Accurate methods for the assessing cardiovascular function are crucial to reduce mortality and morbidity
connected to cardiovascular diseases,” said Dr. Krasimira Hristova, MD, FESC, National Heart Hospital,
Sofia, Bulgaria. “The presence of substantially viable myocardium is recognized as an important
determinant of recovery of LV function after AMI. Assessment of myocardial viability early after acute
infarction provides a valuable tool for prediction of functional recovery with improved clinical outcome.”
The study evaluated 88 subjects: 22 normal volunteers (mean age 31 years ±5), and 66 patients with AMI
(mean age 65 years ±12). Echocardiography was performed in all subjects within 36 hours (baseline), after
revascularization via angioplasty, and after four. Apical and basal short axis images were acquired (frame
rate 67±5 frames/s) and also apical long axis views were analyzed offline in order to extract the strain (rate)
and rotation (rate) curves. Finally, the infarct size was estimated based on MRI delayed enhancement and
expressed as a percentage of the total LV volume.
About the World Congress of Cardiology
The World Congress of Cardiology Scientific Sessions is the official congress of the World Heart Federation
and is held every two years. Through the Congress the World Heart Federation offers an international stage
for the latest developments in science and public outreach in the field of cardiovascular health. The World
Congress of Cardiology places emphasis on the complementary nature of science and public outreach and
strives to spread the message that through individual, community and patient-care interventions, the growing
epidemic of cardiovascular diseases can be prevented. www.worldcardiocongress.org
About the World Heart Federation
The World Heart Federation is dedicated to leading the global fight against heart disease and stroke with a
focus on low- and middle-income countries via a united community of more than 200 member organizations.
With its members, the World Heart Federation works to build global commitment to addressing
cardiovascular health at the policy level, generates and exchanges ideas, shares best practice, advances
scientific knowledge and promotes knowledge transfer to tackle cardiovascular disease – the world’s number
one killer. It is a growing membership organization that brings together the strength of medical societies and
heart foundations from more than 100 countries. Through our collective efforts we can help people all over
the world to lead longer and better heart-healthy lives. For more information, please visit www.worldheart.org
