A new study published in the Journal of the American College of Cardiology found that women are less likely to exhibit signs of structural heart disease, which is a precursor to fatal cardiac arrest. This means that fewer women may be eligible for current treatments that can prevent sudden cardiac arrest.
A large study found acute heart attack patients received an average of 14.5 millisieverts of ionizing radiation, equivalent to 725 chest X-rays, during their hospital stay. Physicians may be unaware of cumulative dose accumulation from tests and should consider radiation exposure when diagnosing and treating heart attacks.
After a heart attack, patients experience shortness of breath and chest pain due to elevated cardiac biomarkers TnT and NTBNP. These biomarkers signal ongoing problems or past issues, highlighting the need for targeted treatment.
Researchers developed microscopic polymer beads that can deliver an antioxidant enzyme into the heart, reducing dying cells and improving heart function after a simulated heart attack. The enzyme, superoxide dismutase (SOD), soaks up toxic free radicals produced during a heart attack.

A Kaiser Permanente program bundled two generic, low-cost drugs and gave daily doses to 68,560 people with diabetes or heart disease for two years, preventing 1,271 heart attacks and strokes. The study found a 60% reduction in hospitalization rates for heart attack or stroke among those taking the bundled drugs.
