Intense light therapy may lower risk of myocardial injuries after non-cardiac surgery

A study published in Annals of Translational Medicine found that intense light therapy can lower troponin levels and increase ANGPTL4 protein, protecting heart tissue. The treatment may reduce the risk of myocardial injuries after non-cardiac surgery, which affects 20% of patients and increases one-year mortality rates.

The heart of female elite athletes adapts differently than those of male elite athletes

Research led by Amsterdam UMC reveals the hearts of female elite athletes have different characteristics compared to their male counterparts. Female athletes exhibit dilation of the heart chambers, whereas males show thickening in combination with a dilation of the heart muscle. This finding can aid doctors in identifying possible hear...

Male bodybuilders face high risk of sudden cardiac death, especially those who compete professionally

A study published in the European Heart Journal found that male bodybuilders have a high risk of sudden cardiac death, with professional bodybuilders facing a more than fivefold increase in risk. The study highlights the need for greater awareness, preventive strategies and policy changes within the bodybuilding community.

Heart vest could help predict sudden cardiac death risk

A new study by UCL researchers suggests that a vest mapping the heart's electrical activity could help identify people at high risk of sudden cardiac death. The electrocardiographic imaging (ECGI) vest combines signals with MRI images to generate 3D models, potentially predicting risk factors for life-threatening heart rhythms.

Cause of sleep disturbance in cardiac disease identified: Ganglia play previously unrecognized role

A study published in Science reveals that ganglia in the neck region are responsible for disrupting melatonin production and causing sleep disturbances in people with heart conditions. Researchers found that macrophages accumulate in the ganglion, leading to inflammation and scarring, which can be treated with drugs.

CNIC scientists uncover opposing roles of p38 proteins in cardiac hypertrophy

A study by CNIC scientists has identified a key role for the MKK3/6–p38γ/δ signaling pathway in cardiac hypertrophy. Inhibition of p38α promotes an unexpected activation of the other branch of the pathway, consisting of the proteins MKK3, p38γ, and p38δ. This activation induces another key pathway in cardiac hypertrophy, the mTOR pathway.

Molecular pathway driving maladaptive processes in heart failure elucidated by scientists at Lewis Katz School of Medicine at Temple University, opening door to new therapeutic strategies

Researchers at Lewis Katz School of Medicine at Temple University discover a molecular pathway driving maladaptive processes in heart failure, revealing the importance of GRK5's catalytic activity and nuclear presence. The study opens doors to new therapeutic strategies for treating this devastating condition.

CNIC scientists describe one of the mechanisms underlying cardiac hypertrophy

Researchers at CNIC have identified a new mechanism involved in the regulation of cardiac hypertrophy, which may spur the development of new tools for its treatment. The SRSF4-GAS5-glucocorticoid receptor axis plays a crucial role in regulating ventricular function and preventing excessive heart muscle growth.

A change of heart

Cardiac diseases cause pathological growth leading to heart failure. Researchers found epigenetic marks responsible for this growth are lost in disease, allowing cells to switch back to fetal form and leading to irregular rhythms. This finding points to a new strategy for epigenetic therapy.

Researchers ID genetic cues for a big heart

Duke researchers discovered a gene called Raf that acts as a switch to turn on Yorkie, making fly hearts grow bigger. The study sheds light on the genetic circuitry of signals governing growth and may help understand how human hearts respond to disease.

'SIRT'ain security: the protein SIRT3 protects the heart

A new study reveals that Sirt3 helps protect the mouse heart by blocking cardiac hypertrophic response through Foxo3a-dependent antioxidant defense mechanisms. Mice lacking Sirt3 developed enlarged hearts, while those overexpressing Sirt3 were protected from cardiac hypertrophy under similar conditions.

Researchers developed a new mouse model to predict the loss of orally taken drugs due to metabolism by CYP3A, a key enzyme involved in first-pass metabolism. The study found that mice lacking functional CYP3A proteins accumulated docetaxol at higher levels, demonstrating the enzyme's role in intestinal metabolism.

Decreased diabetic cardiac death from losartan?

A post-hoc analysis of the LIFE study found that losartan significantly reduced sudden cardiac death in diabetic patients with hypertension and left ventricular hypertrophy compared to atenolol. The results showed a nearly 50% risk reduction in sudden death for losartan-treated patients.
