BACKGROUND: The efficacy of continuous retrograde del Nido cardioplegia for myocardial protection is still controversial. We hypothesised that antegrade and retrograde cardioplegia offer equivalent safety for myocardial protection in the David I procedure. METHODS: We retrospectively reviewed 33 patients undergoing the David I operation with antegrade or retrograde del Nido solution from June 2014 to January 2016. The outcomes were compared. The follow-up was 1 month to 15 months...

Arsenic trioxide (As2O3) is utilized for treating patients suffering from hematological malignancies particularly acute promyelocytic leukemia. Unfortunately, the extensive application of this chemotherapeutic agent has been limited due to its adverse effects such as cardiotoxicity. Ellagic acid, as a phenolic compound, has shown to exert antioxidant, anti-inflammatory, antifibrotic, and antiatherogenic properties. It is also capable of protecting against drug toxicity. In this study, we evaluated whether ellagic acid can protect against As2O3-induced heart injury in rats...

BACKGROUND: Prostaglandin E1 (PGE1) is widely used as a pretreatment for myocardial reperfusion injury in animal experiments. However, the cardioprotective effects of PGE1 in patients have not been established. We performed a meta-analysis to investigate whether PGE1 is cardioprotective, based on the reduction of correlative reperfusion injury events (CRIE), major adverse cardiac events (MACE), and biomarker release in patients with ischemia reperfusion injury. METHODS: The Medline, EMBASE, and Cochrane databases were searched for randomized clinical trials confirming the effects of PGE1...

Doxorubicin (DOX) is a highly effective antineoplastic drug; however, the clinical use of DOX is limited by its dose dependent cardiotoxicity. This study was conducted to evaluate the cardioprotective effect of sea cucumber and valsartan against DOX-induced cardiotoxicity in rats. Also, the role of exposure to low dose γ radiation (LDR) on each of them was investigated, since LDR could suppress various reactive oxygen species-related diseases. Rats received DOX (2.5mg/kg, ip) in six equal injections over a period of 2weeks, sea cucumber (14...

PURPOSE: Methotrexate is an anti-inflammatory drug that has been shown to have anti-ischemic effects. Our aim was to evaluate if methotrexate could reduce infarct size in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: We randomly assigned patients with STEMI to receive either methotrexate or placebo. Primary outcome was infarct size determined by calculating the area under the curve (AUC) for creatine kinase (CK) release. Secondary outcomes were AUC of CK MB (CK-MB) and AUC of troponin I; peak CK, peak CK-MB, and troponin I; B-type natriuretic peptide (BNP) level, high-sensitivity C-reactive protein (hsCRP) result, and erythrocyte sedimentation rate (ESR); left ventricular ejection fraction (LVEF); thrombolysis in myocardial infarction (TIMI) frame count; Killip score; mortality and reinfarction incidence; and incidence of adverse reactions...

Rapid ventricular pacing (RVP) is used during transcatheter aortic valve implantation (TAVI). RVP disturbs myocardial oxygen balance, and when prolonged, it may cause procedure-related myocardial injury (PMI). This study investigated whether a longer duration of RVP increased the occurrence of PMI or worsened long-term mortality after TAVI. We retrospectively analyzed data from 188 patients who underwent TAVI in our institute from January 2013 to July 2015. Myocardial injury was represented by the peak value of creatine kinase-myocardial band (CK-MB) within 72 h after the procedure; an increase greater than 5 times the upper reference limit was regarded as PMI...
