Women at heart: Stop the bias

A study of 3779 patients found women were 20% less likely to undergo an exercise test or angiography due to suspected coronary obstruction. Despite proven coronary disease, women received less aggressive treatment and were twice as likely to die or suffer a heart attack compared to men.

Casting a wide net to fight coronaviruses

A team of researchers has developed an antiviral inhibitor that is active against several coronaviruses, including those causing the common cold and SARS. The compound targets the main protease enzyme, which is crucial for viral replication, and shows promise as a potential treatment for coronavirus-related diseases.

Cardiac benefits of sport

Increased physical activity reduces coronary heart disease and cardiac mortality rates by 30-40% compared to inactive individuals. Exercise training also improves endothelial function, reducing atherosclerosis and plaque formation, and can even extend life expectancy in patients with stable coronary artery disease.

Arrhythmias and sport

The study found that adolescents and young adults involved in competitive sports had a two and a half times higher risk of sudden death. ECG screening identified vulnerable young people, reducing sports-related sudden death from hypertrophic cardiomyopathy.

Interpersonal and social rhythm therapy proven to be an effective treatment for bipolar disorder

Interpersonal and Social Rhythm Therapy (IPSRT) has been found to be an effective treatment for bipolar disorder, helping patients manage daily routines and relationships to prevent mania and depression. The study suggests that IPSRT is particularly beneficial for individuals with more regular social routines and better physical health.

Percutaneous aortic valve replacement

The Cribier-Edwards Percutaneous valve offers a less invasive solution for patients with fibro-calcific native aortic valves, reducing mortality rates associated with untreated disease. Recent developments include custom retrograde delivery systems and larger valve sizes, improving procedure success rates.

NORVIT

Researchers from Norway found that treating patients with high doses of B vitamins after a heart attack does not prevent recurrent heart disease or stroke. In fact, high doses of B vitamins may increase the risk of cardiovascular disease, particularly among those with impaired renal function.

ESC Congress 2005: ISSUE II

A new study demonstrates that improved patient selection methods lead to significantly better therapy outcomes for patients with suspected neurally-mediated syncope. The study used implantable loop recorders and found a lower recurrence rate in patients who received pacemaker therapy.
