Hyperglycemia-induced reactive oxygen species (ROS) generation contributes to development of diabetic cardiomyopathy. Nuclear factor E2-related factor 2 (Nrf2), a redox-sensing transcription factor, induces the antioxidant enzyme expressions. Diallyl trisulfide (DATS) is the most powerful antioxidant among the sulfur-containing compounds in garlic oil. We investigated whether DATS inhibits hyperglycemia-induced ROS production via Nrf2-mediated activation of antioxidant enzymes in cardiac cells exposed to high glucose (HG). ⋯ Our findings indicate that DATS protects against hyperglycemia-induced ROS-mediated apoptosis by upregulating the PI3K/Akt/Nrf2 pathway, which further activates Nrf2-regulated antioxidant enzymes in cardiomyocytes exposed to HG.

β-blocker use in patients after percutaneous coronary interventions: one size fits all? Worse outcomes in patients without myocardial infarction or heart failure.
The influence of β-blocker therapy on prognosis in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI) has not been fully explored. ⋯ β-blocker therapy was associated with worse 3-year clinical outcomes in CAD patients who underwent PCI but had no history of MI or HF. Randomized trials are warranted to identify appropriate subsets of patients who could truly benefit from long-term use of β-blockers in this setting.
