Patients treated with beta blocker metoprolol for 30 days before and after noncardiac surgery were less likely to have heart attacks, but more likely to die or have strokes one year later. The study found that the benefits of beta blockers in reducing heart attacks did not outweigh the increased risk of death or stroke.
A study found that women with breast cancer who took the beta blocker carvedilol during chemotherapy had lower levels of a protein indicative of heart injury, but no difference in heart function. The study's lead author notes that further research is needed to confirm these findings and explore potential benefits for higher-risk patients.
A large trial found that statins significantly reduced major adverse cardiac events among patients undergoing PCI, but not in the broader population.

A new study by researchers at the University of Gothenburg supports the notion that Selective Serotonin Reuptake Inhibitors (SSRIs) exert a specific antidepressant effect. Contrary to the 'placebo effect' theory, SSRIs are shown to be effective in treating depression, even in patients without side effects.
A study found that steroid treatment for IgA nephropathy was associated with a significantly higher risk of serious adverse events, primarily infections. The trial was stopped early due to an unexpectedly high rate of serious infections and two deaths.
