  • Percutaneous extracorporeal life support (P-ECLS) is a useful modality for the management of refractory cardiac or pulmonary failure. However, venoarterial P-ECLS may result in a complication of left ventricular distension. In this case report, we discuss a patient with drug-induced dilated cardiomyopathy managed with venoarterial P-ECLS and a left atrial vent catheter. The venoarterial P-ECLS was modified to a paracorporeal left ventricular assist device (LVAD) by removing the femoral venous cannula. After 28 days of hospitalization, the patient was successfully weaned from the paracorporeal LVAD and discharged home from the hospital.

  • Soluble epoxide hydrolase (sEH) is a metabolic regulator of epoxyeicosatrienoic acids (EETs). EETs have many beneficial effects, vasodilation, anti-diabetes, anti-inflammation, cardiovascular protection, renal protection. Therefore, selective sEH inhibitors have a potential for treating these diseases. In the present study, screening methods for sEH inhibitors using PHOME ((3-phenyl-oxiranyl)-acetic acid cyano-(6-methoxynaphthalen-2-yl)-methyl ester) and 14-15-EET as substrates were established. To determine selectivity, microsomal epoxide hydrolase (mEH) inhibition assay was also developed using styrene oxide as a substrate of microsomal epoxide hydrolase. Our results obtained from 12-[[(tricyclo[3.3.1.13,7]dec-1-ylamino)carbonyl]amino]-dodecanoic acid (AUDA) used as a positive sEH inhibitor and valpromide used as a positive mEH inhibitor showed that these methods are useful for discovery of drug candidates.

  • The aim of this study was to fabricate a dextran polyelectrolyte multi-layer on a bare metal stent (BMS) and to evaluate bio-physical properties of the layer. Diethylaminoethyl-dextran (DEAE-D) as a polycation and dextran sulfate (DS) as a polyanion were successively coated on the bare metal stent by a well-known layer-by-layer procedure. The morphology of the stent surface and its cell adhesion were studied after each coating step by scanning electron microscopy. The stent showed more blotched and slightly rougher morphology after dextran-DS coating. The contact angle of the DEAE-DS group ($39.5{\pm}0.15^{\circ}$) was significantly higher than that of the BMS group ($45.16{\pm}0.08^{\circ}$), indicating the improvement of hydrophilic. The SMC proliferation inhibition in the DEAE-DS-coated stent group ($20.9{\pm}0.04%$) was stronger than that in the control group ($21.7{\pm}0.10%$ in DS-coated group only). The DEAE-DS coating is desired for stent coating materials with biocompatibility and anti-restenosis effect.

  • Clopidogrel is used to reduce the risk of cardiovascular events in patients with atherosclerosis documented by recent ischemic stroke, recent myocardial infarction (MI), or established peripheral arterial disease (secondary prevention). Clopidogrel is metabolized by CYP3A4, and the active metabolites inhibit platelet aggregation. The purpose of this study was to assess clopidogrel only versus clopidogrel + others (aspirin, CYP3A4 inhibitor, and CYPBA4 inducer) in terms of cardiovasculalr events and bleeding complications. We reviewed the charts of patients who visited between August 1, 2002 and August 31, 2003, retrospectively. Total 72 patients were included and they consisted of 5 groups; clopidogrel group (n=36), clopidogrel + aspirin group (n=11), clopidogrel + CYP3A4 inhibitor group (n=15), clopidogrel + aspirin + CYP3A4 inhibitor group (n=6), clopidorel + CYP3A4 inducer group (n=4). The primary endpoints at 6 months, 12 months were the composite of cardiovascular (CV) events. The secondary end-point was the incidence of bleeding events at 6months, and 12months. At 12months, the primary endpoint was not significantly different among the five groups (p=0.056). In comparison of two groups as clopidogrel only versus clopidogrel + others (aspirin, CYP3A4 inhibitor and CYP3A4 inducer), the primary endpoint was significantly different (p=0.02). The CV events were increased in the clopidogrel + others group. The secondary end point was not significantly different among the five groups (p=0.52). However, time to bleeding events was 230.8 in the clopidogrel group and 74.7 in the clopidogrel + others group (p = 0.046). In conclusion, clopidogrel interaction with aspirin, CYP3A4 inhibitor, and CYP3A4 inducer affected cardiovascular events and bleeding events. Drug interaction of clopidogrel with concurrent medications should be considered cautiously.

  • Background and Objectives: Real-world clinical data, outside of clinical trials and expert centers, on adverse events related to the use of SyncCardia total artificial heart (TAH) remain limited. We aim to analyze adverse events related to the use of SynCardia TAH reported to the Food and Drug Administration (FDA)'s Manufacturers and User Defined Experience (MAUDE) database. Methods: We reviewed the FDA's MAUDE database for any adverse events involving the use of SynCardia TAH from 1/01/2012 to 9/30/2020. All the events were independently reviewed by three physicians. Results: A total of 1,512 adverse events were identified in 453 "injury and death" reports in the MAUDE database. The most common adverse events reported were infection (20.2%) and device malfunction (20.1%). These were followed by bleeding events (16.5%), respiratory failure (10.1%), cerebrovascular accident (CVA)/other neurological dysfunction (8.7%), renal dysfunction (7.5%), hepatic dysfunction (2.2%), thromboembolic events (1.8%), pericardial effusion (1.8%), and hemolysis (1%). Death was reported in 49.4% of all the reported cases (n=224/453). The most common cause of death was multiorgan failure (n=73, 32.6%), followed by CVA/other non-specific neurological dysfunction (n=44, 19.7%), sepsis (n=24, 10.7%), withdrawal of support (n=20, 8.9%), device malfunction (n=11, 4.9%), bleeding (n=7, 3.1%), respiratory failure (n=7, 3.1%), gastrointestinal disorder (n=6, 2.7%), and cardiomyopathy (n=3, 1.3%). Conclusions: Infection was the most common adverse event following the implantation of TAH. Most of the deaths reported were due to multiorgan failure. Early recognition and management of any possible adverse events after the TAH implantation are essential to improve the procedural outcome and patient survival.

  • This study was designed to elucidate the anti-inflammatory, cardiovascular, anti-thrombotic and analgesic effects of Shintongchugeotang. The anti-inflammatory effect was measured by the method of carragenin induced edema, protein leakage test using CMC-pouch, and the analgesic effect was measured by the acetic acid method and hot plate method, and the effect of Shintongchugeotang on the cardiovascular system was observed by the change of flow rate of Ringer solution in the vascular system in the ear of rabbit, and the contraction and dilatation of rat tail artery. Death rate, platelet aggregation, plasma coagulation activity was observed for the measurement of the anti-coagurative effect of Shintongchugeotang. The result was as follows : 1. After the administration of Shintongchugeotang extract, Carragenin induced edema and CMC-pouch protein leakage were significantly decreased. 2. The slight analgesic effect of Shintongchugeotang extract was confirmed by the observation of writhing syndrome, paw licking time, and escape time. 3. The drug increased the auricular blood flow in rabbit. 4. The drug relaxed the artery contraction by pretreated norepinephrine in rat. 5. The drug inhibited the death rate of mouse which was led to thromboembolism by serotonin and collagen. 6. The drug inhibited the platelet aggregation in rat. 7. The drug prolonged the prothrombin time and activated partial thromboplastin time on the test of plasma coagulation factor activity in rat, but was not valuable.

  • This review summarizes gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions. Gender differences in pharmacokinetics are categorized by four major factors: absorption/bioavailability, distribution, metabolism, and elimination. There are sex-based differences in gastric emptying time, gastric alcohol dehydrogenase activity, apparent volume of distribution, ${\alpha}1$-acid glycoprotein level, phase I (CYP) and phase II metabolizing enzymes, glomerular filtration rate, and drug transporters. This review also reports gender differences in pharmacokinetics and pharmacodynamics of cardiovascular agents, central nervous system acting agents and antiviral agents. In addition, it has been reported that females experience more adverse reactions such as coughing, tachycardia, nausea, vomiting, rash, hypersensitivity, hepatotoxicity, and metabolic disorder after taking cardiovascular, central nervous system acting and antiviral agents. Therefore, in order to provide optimal drug dosage regimens both in male and female, gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions must be considered.
