A large international clinical trial found that stable patients who received late angioplasty after a heart attack did not have better outcomes than those on medical therapy alone. The study suggests that routine late opening of the blocked artery is unnecessary and should be reserved for unstable patients.
A new study published in the New England Journal of Medicine found that patients who undergo angioplasty to open their totally blocked coronary arteries days after a heart attack do not reduce their risk of having another heart attack, going into heart failure, or dying. The study, which involved over 2,166 patients on five continents,...

A new study finds that health care spending generates significant health benefits, with a return on investment of $1.55 to $1.94 for every dollar spent. The research demonstrates the value of estimating the impact of health care investments and challenges policymakers to consider cost-effectiveness in their decision-making.
A team of researchers has identified a potential alternative therapeutic option to COX-2 inhibitors by targeting microsomal prostaglandin E synthase-1 (mPGES-1). Inhibiting mPGES-1 suppresses PGE2 expression while augmenting PGI2 production, without affecting blood clotting or blood pressure.
Researchers found that low-dose aspirin prevents platelet clumping in both sexes, with women's platelets reacting more strongly to aspirin before treatment. The study suggests that further research is needed to determine who benefits from aspirin and under what circumstances it works.
A new study published in JAMA found that women are at a higher risk of developing angina, a symptom of chest pain or discomfort due to insufficient oxygen supply to the heart muscle. Women with angina and diabetes are particularly at risk of experiencing high rates of death from heart disease

Researchers analyzed data from 30,324 heart attack patients treated at U.S. hospitals and found that the BNP test was primarily used on high-risk patients with congestive heart failure or older age. However, younger and seemingly healthier patients with elevated BNP levels were at a two to four times greater risk of dying in the hospital.
Researchers found Computed Tomographic Angiography (CTA) quickly and accurately ruled out coronary artery disease in 67% of cases, reducing hospital stay by 45% and saving $300 per patient.
