Older women who have their first heart attack face a serious risk of death. Researchers looked at post‑menopausal women who were part of a large health study to see how many survived and what factors influenced their chances. The study followed these women over time, recording when they had a hear
After a heart attack, the body's defense system kicks in. It's like a cleanup crew showing up to fix the damage. But how does this crew know where to go and what to do? It turns out, tiny messengers called chemokines play a big role. These messengers are like text messages sent by special cells in
Heart attacks are serious, and spotting them early is crucial. Scientists have been working on new ways to see heart damage using special tiny particles and advanced imaging. These particles, called nanoparticles, are not new. But the way they are used here is different. The usual method involves u
Type 2 myocardial infarction, or T2MI, is a type of heart attack that doesn't fit the usual pattern. It's not caused by a blockage in the heart's arteries, but rather by other issues like low blood pressure or a heart rhythm problem. This makes it tricky to spot and treat. Researchers looked at a b
After a heart attack, the heart needs new blood vessels to heal and work better. But the low-oxygen environment after a heart attack makes it hard for these new vessels to form. ATF4 is a protein that might help with this process. Scientists did some experiments to see how ATF4 works. They used cel
Heart disease is a big deal. It's one of the leading causes of death worldwide. But what if we could use our genes to predict who is at risk? That's where polygenic risk scores (PRS) come in. These scores look at many genes to see if someone might be more likely to develop coronary artery disease (C
After a heart attack, the body's immune system kicks into high gear. It's like a rescue team rushing to the scene. Among these immune cells, a specific type called regulatory T cells (Tregs) has caught the attention of researchers. These Tregs produce a protein called Amphiregulin (AREG). This prote
Heart attacks are scary. They happen when blood flow to the heart is blocked. This can cause serious damage. But what if there was a way to help the heart heal itself? Enter SNHG15, a long non-coding RNA. It's a type of molecule that doesn't make proteins but plays a big role in how cells work.
Cancer patients face a unique challenge when it comes to detecting heart attacks. The standard tests, which rely on high-sensitivity cardiac troponin T/I (hs-cTnT/I), often fall short in this group. This is where the European Society of Cardiology (ESC) 0/1-h hs-cTnT/I algorithms come into play. The
Heart attacks are scary and can happen suddenly. Doctors need to act fast. That means a lot of tests and checks. Some of these tests are pretty new. They can spot problems quickly. This can save time and money. But are they always the best choice? First, let's talk about heart attacks. They
