Best use of drug-eluting stents

Drug-eluting stents should be avoided in patients with diabetes, short lesions, or large vessel sizes due to high restenosis risk. Extended dual antiplatelet therapy also poses bleeding complications, making bare metal stents a safer option for some patients

DES: New elements in the debate

Recent studies on DES have shown mixed results, with some suggesting increased risk of late thrombosis but no impact on mortality or myocardial infarction. However, other data indicate benefits in terms of reduced reinterventions and improved outcomes for high-risk patients.

The TRANSCEND study

The TRANSCEND study found that telmisartan modestly reduced the outcome of cardiovascular death, heart attack, stroke, and hospitalization for heart failure. Additionally, fewer patients receiving telmisartan were hospitalized for any cardiovascular reason compared to placebo.

The BEAUTIFUL study

The BEAUTIFUL study shows ivabradine significantly reduces hospitalization for fatal and non-fatal myocardial infarction by 36% and coronary revascularisation by 30% in high-heart-rate patients. Ivabradine is safe and well-tolerated, even when used with other cardiovascular drugs.

Genetic testing?

Genetic testing has significantly improved the detection of individuals at risk for sudden cardiac death in athletes. This technology enables informed decision-making regarding care and training continuation among athletes. However, its use in asymptomatic genetic carriers with normal phenotypes is a topic of controversy.

New genes found for inflammatory bowel disease in children

Researchers have discovered two new genes that increase the risk of developing childhood inflammatory bowel disease. The study found a compelling candidate, TNFRSF6B, which is involved in tumor necrosis factor signaling and may provide a target for drug development.

Computed tomography provides anatomy -- we need ischemia!

Cardiac computed tomography (CTA) is reliable for excluding coronary artery disease but lacks hemodynamic relevance and poses radiation risks. Fundamental insights into CAD suggest a graded prognosis according to ischemia severity, making revascularization unnecessary in some cases.

LEADERS (Limus Eluted from A Durable versus ERodable Stent coating)

The LEADERS study found that a biolimus-eluting stent with a biodegradable polymer is as safe and effective as a sirolimus-eluting stent with a durable polymer, reducing the risk of restenosis. The results suggest that this new generation of drug-eluting stents may offer improved long-term safety and effectiveness.

Sex hormones link to heart risk

A new study led by the University of Leicester found that men's sex hormones, particularly estradiol and estrone, are associated with increased cardiovascular risk factors such as high total cholesterol and LDL-cholesterol. This suggests that natural endogenous estrogens may play a role in increasing heart disease risk in men.

Neurogenesis in the adult brain: The association with stress and depression

The adult brain's capacity for neurogenesis is closely tied to stress and depression, with research showing that chronic stress can inhibit new cell growth in the hippocampus. However, antidepressant treatment has been shown to stimulate neurogenesis, suggesting a potential therapeutic target for treating major depressive disorders.
