Acute Coronary Syndromes

Acute coronary syndrome (ACS) is most commonly caused by a heart attack (myocardial infarction) where blood flow to the heart is suddenly blocked. This is usually caused by a blood clot from a ruptured coronary artery atherosclerotic plaque. Other causes include spontaneous coronary artery dissection (SCAD), which most commonly occurs in women. ACS is usually treated in a cath lab with angioplasty and the placement of a stent to prop the vessel open.

Beta-blockers do not benefit heart attack patients with a normal LVEF
The new meta-analysis included data from nearly 18,000 patients. Overall, patient outcomes were quite similar for patients who did and did not undergo beta-blocker therapy.
AI dramatically improves the detection of severe heart attacks
Researchers put an advanced AI model to the test, using it to evaluate the ECG results of more than 1,000 patients. It performed quite well.
Stem cell patch shows potential to heal heart patients—no surgery or transplant required
The new patch is implanted through a tiny incision and held in place with a biocompatible adhesive. It then helps the heart recover over time, replacing dead tissue that would typically never be able to regenerate.
COVID-19, other infections linked to major cardiovascular risks—researchers push for vaccination
Adults are three times as likely to have a heart attack or stroke after a COVID-19 infection than when they are healthy. The risks are even greater for the flu.
FDA clears new AI-enabled coronary plaque analysis software
Circle Cardiovascular Imaging, a Canadian medtech company, received the key approval for its cvi42 | Plaque platform.

A promising SELUTION: Sirolimus-eluting balloon from Cordis makes impression at TCT 2025

The SELUTION SLR Drug-Eluting Balloon was the topic of two different late-breaking clinical trials at TCT 2025. Both studies found that the device was noninferior to traditional treatments after one year. Long-term data are still needed.

Poor oral health tied to much higher risk of heart attack, stroke

Regularly going to the dentist, researchers added, may reduce cardiovascular risks by a significant margin.

PCI for eruptive calcified nodules: Drug-eluting stents, drug-coated balloons both linked to poor outcomes

In some cases, researchers noted, CABG may be a better treatment option. The group emphasized that alternative therapies are still needed to improve patient care.
