Current practice of testing athletes at rest may miss signs of right ventricular dysfunction that can lead to sudden death. A new study shows that exercise echocardiography can detect changes in the right ventricle's functioning during physical activity, providing a potential diagnostic tool for cardiologists managing athletes.
A new study by SEPTAL-CRT found that mid-septal RV lead placement in heart failure patients undergoing CRT results in similar outcomes compared to the conventional apical position. The study showed no differences in clinical outcome or implantation success rates between the two groups.
Research associates high traffic-related air pollution exposure with increased right ventricular mass and volume, linking it to a higher risk of heart failure and cardiovascular death. The study found that participants exposed to higher levels of nitrogen dioxide had greater right ventricular changes.
Researchers tracked premature babies into their 20s and found that those born prematurely had a smaller but heavier right ventricle with thicker walls and less pumping capacity. The earlier the birth, the greater the impact on right ventricle size and function.
A UAlberta research team found that medications for Pulmonary Arterial Hypertension (PAH) could have adverse effects on the heart. ERAs decrease the strength of contraction in diseased right ventricles, which may be beneficial due to increased endothelin levels.
A new study finds that physical fitness significantly lowers the risk of death in diabetes patients with heart abnormality. Diabetic patients who were physically fit had a lower risk of death compared to those who were not physically fit, regardless of the presence or absence of left ventricle wall thickness.
A new study uses advanced imaging to measure tricuspid valve anatomy and predict the severity of leakage. The research found that pulmonary arterial pressure, annulus area, and papillary muscle position are correlated with the grade of tricuspid regurgitation.
Researchers found that extreme endurance exercise can cause damage to the right ventricle of the heart, which can lead to arrhythmias and reduced performance. While the damage is reversible in most athletes, five out of 40 studied showed permanent scarring, suggesting a susceptibility to long-term effects.
The CRISP AMI trial found that intra-aortic balloon counterpulsation does not reduce infarct size in patients with ST segment elevation myocardial infarction (STEMI) without cardiac shock. The study showed no significant difference in infarct size between the groups, but IABC was associated with lower mortality rates.
A new medication, ivabradine, has been shown to reduce both heart rate and volume in patients with cardiac insufficiency, leading to a significant reduction in mortality and hospitalizations. This discovery holds promise for a new approach to treating this condition.
A study found that ICD patients are living longer, with an average of nine years after implantation. However, right ventricular pacing negatively affects survival rates, while cardiac resynchronization therapy (CRT) improves outcomes.
A recent study presented at the American Society of Echocardiography conference supports the safety profile of GE Healthcare's diagnostic heart ultrasound contrast agent Optison. The study data confirm that Optison is safe for use in patients with certain medical conditions, providing further assurance of its efficacy and safety.
The right ventricle's size and pumping ability vary by age, gender, and ethnicity, with older adults having smaller but stronger hearts. The study found that men have larger right ventricles than women, while African-Americans have smaller ones compared to Caucasians.
A new study from the Heart and Stroke Foundation of Canada found that marathon runners who are not adequately prepared can experience heart damage due to inadequate aerobic fitness. The study used MRI measurements to determine who is at risk of cardiac injury, highlighting the importance of proper training and cardiovascular testing.
Researchers identified molecular changes and right ventricular diastolic dysfunction in patients with restrictive ventricular septal defect, a seemingly benign congenital heart disease. Early detection and treatment may prevent future complications and improve outcomes for these patients.
Researchers at Henry Ford Hospital found that a continuous flow left ventricular assist device (LVAD) improves function on the right side of the heart, reducing central venous pressure and pulmonary artery pressures. The study, which monitored 41 patients, also showed significant improvements in measures related to tricuspid regurgitat...
Researchers found that lower oxygen saturation is associated with left ventricle hypertrophy and diastolic dysfunction in children with sickle cell disease. The study suggests that the beginning of adult heart disease may start in childhood, highlighting the need for further research.
Research found that long-term anabolic steroid users had weaker left ventricle function and impaired diastolic function compared to non-steroid users. Eighty-three percent of steroid users had low ejection fraction, linked to increased risk of heart failure and sudden cardiac death.
Researchers found that abnormal QRS duration is a significant predictor of sudden cardiac death, especially in patients with hypertension. The study suggests that regular electrocardiograms can be used as a warning signal for increased risk of sudden cardiac death.
Researchers found that nuclear stress tests can detect diastolic dysfunction with a high specificity rate, identifying patients at risk of heart failure. The test plots out the heartbeat and measures the left ventricle filling pressure, providing a prognostic value in predicting diastolic dysfunction.
A recent study presented at TCT symposium showed that the vast majority of patients who underwent MitraClip procedure did not need surgery three years later and experienced improved left ventricle function. The device also reduced mitral regurgitation severity and promoted reverse remodeling, leading to better patient outcomes.
A novel catheter technique successfully patched ventricular septal defects (VSDs) in nearly all patients, restoring normal blood circulation and relieving fluid backup in the lungs. After recovery, patients regained enough strength to safely undergo surgical repair or return to active lives.
A new study published in the European Heart Journal has found that high-level endurance athletes with ventricular arrhythmias often have dysfunctional right ventricles. The research suggests that endurance exercise may contribute to changes in the heart that lead to dysfunction and heart rhythm disturbances.
A study in mice identifies genetic origins of cardiomyopathy for the first time, revealing a link to the desmoplakin gene and progressive heart disease. The discovery may lead to better understanding and targeted therapies for patients with arrhythmogenic right ventricular cardiomyopathy.
A new study shows that the GeoForm mitral valve repair ring can reverse damage caused by congestive heart failure and improve symptoms in patients with severe mitral valve regurgitation. The ring has been approved for tightening leaky mitral valves, but also changes the shape of the left ventricle to help it contract better.
A study published in Circulation found that smoking causes the aorta to stiffen, reducing its ability to relax and widen. This can lead to increased pressure on the left ventricle, which pumps blood throughout the body.
