    BACKGROUND: We sought to investigate the influence of the extent of myocardial injury on left ventricular (LV) systolic and diastolic function in patients after reperfused acute myocardial infarction (AMI). METHODS: Thirty-eight reperfused AMI patients underwent cardiac magnetic resonance (CMR) imaging after percutaneous coronary revascularization. The extent of myocardial edema and scarring were assessed by T2 weighted imaging and late gadolinium enhancement (LGE) imaging, respectively. Within a day of CMR, echocardiography was done. Using 2D speckle tracking analysis, LV longitudinal, circumferential strain, and twist were measured. RESULTS: Extent of LGE were significantly correlated with LV systolic functional indices such as ejection fraction (r��=��-0.57, p��<��0.001), regional wall motion score index (r��=��0.52, p��=��0.001), and global longitudinal strain (r��=��0.56, p��<��0.001). The diastolic functional indices significantly correlated with age (r��=��-0.64, p��<��0.001), LV twist (r��=��-0.39, p��=��0.02), average non-infarcted myocardial circumferential strain (r��=��-0.52, p��=��0.001), and LV end-diastolic wall stress index (r��=��-0.47, p��=��0.003 with e') but not or weakly with extent of LGE. In multivariate analysis, age and non-infarcted myocardial circumferential strain independently correlated with diastolic functional indices rather than extent of injury. CONCLUSIONS: In patients with timely reperfused AMI, not only extent of myocardial injury but also age and non-infarcted myocardial function were more significantly related to LV chamber diastolic function.ope

    Efficacy and Safety of Da-Chai-Hu-Tang in Lipid Profiles in High-Risk, Statin-Treated Patients with Residual HyperTG: A 12-Week, Randomized, Active-Control, Open Clinical Study

    Da-Chai-Hu-Tang (DCHT) is a herbal extract that has been shown to reduce serum triglyceride (TG) levels in animal experiments as well as small clinical trials. This study aimed to evaluate the efficacy and safety of DCHT in high-risk, statin-treated patients with residual hypertriglyceridemia (hyperTG). This was a 12-week, randomized, active-controlled, open-label, single-center trial. Of these patients, 42 had high cardiovascular risks whose LDL cholesterol levels were controlled by statin treatment; however, with TG levels of 200 to 500 mg/dL they were randomly assigned 1:1 to the OMEGA3 or DCHT group. The primary endpoint was defined as the percentage change in TG at 12 weeks, and changes in other lipid profiles and endothelial cell function were included as secondary endpoints. Safety analyses were also conducted. In the OMEGA3 group, the average TG level decreased from 294.5 &plusmn; 72.0 to 210.0 &plusmn; 107.8 mg/dL (p = 0.004), and in the DCHT group, from 288.7 &plusmn; 59.1 to 227.5 &plusmn; 98.1 mg/dL (p = 0.001). The percentage change in TG was &minus;27.6 &plusmn; 33.6 and &minus;22.4 &plusmn; 24.1 (p = 0.58), respectively, and there was no significant difference between the two groups. There were no severe adverse events in either group. In high-risk, statin-treated patients with residual hyperTG, the administration of OMEGA3 or DCHT for 12 weeks resulted in a significant reduction in TG, and the effect of DCHT was not inferior to that of OMEGA3

    Efficacy and safety of electroacupuncture in acute decompensated heart failure: a study protocol for a randomized, patient- and assessor-blinded, sham controlled trial

    Abstract Background The purpose of this trial is to evaluate the effectiveness and safety of electroacupuncture in the treatment of acute decompensated heart failure compared with sham electroacupuncture. Methods This protocol is for a randomized, sham controlled, patient- and assessor-blinded, parallel group, single center clinical trial that can overcome the limitations of previous trials examining acupuncture and heart failure. Forty-four acute decompensated heart failure patients admitted to the cardiology ward will be randomly assigned into the electroacupuncture treatment group (n = 22) or the sham electroacupuncture control group (n = 22). Participants will receive electroacupuncture treatment for 5 days of their hospital stay. The primary outcome of this study is the difference in total diuretic dose between the two groups during hospitalization. On the day of discharge, follow-up heart rate variability, routine blood tests, cardiac biomarkers, high-sensitivity C-reactive protein (hs-CRP) level, and N-terminal pro b-type natriuretic peptide (NT-pro BNP) level will be assessed. Four weeks after discharge, hs-CRP, NT-pro BNP, heart failure symptoms, quality of life, and a pattern identification questionnaire will be used for follow-up analysis. Six months after discharge, major cardiac adverse events and cardiac function measured by echocardiography will be assessed. Adverse events will be recorded during every visit. Discussion The result of this clinical trial will offer evidence of the effectiveness and safety of electroacupuncture for acute decompensated heart failure.

    Acute Effect of Evolocumab on Lipoprotein(a) Level and Inflammation in Patients with Coronary Artery Disease

    Background: Several studies have shown that high plasma lipoprotein(a) concentrations are associated with an increased risk of arteriosclerotic cardiovascular disease. Thus, Lp(a) has emerged as a new therapeutic target. Circulating proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are new lipid-lowering agents that reduce low-density lipoprotein cholesterol as well as Lp(a). Methods: We analyzed the short-term effects of one-time administration of evolocumab (a PCSK9 inhibitor) on the lipid profiles (especially Lp(a)) and inflammatory markers in Korean patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). Sixty-four patients with CAD who underwent PCI were enrolled in this trial. Evolocumab (140 mg) was administered to patients within 24 h after PCI. Lipid profiles and inflammatory marker levels were measured at baseline and 2 weeks later. Results: The PCSK9 inhibitor significantly reduced the baseline levels of Lp(a) (&minus;9.2 mg/dL, p &lt; 0.001), but high-sensitivity C-reactive protein (+0.07 mg/dL, p = 0.272) was not significantly different after 2 weeks. In patients with an Lp(a) level of 50 mg/dL or more, the Lp(a) level decreased significantly by approximately 30%, from 95.6 mg/dL to 67.0 mg/dL (p &lt; 0.001). Conclusions: One-time PCSK9 inhibitor treatment may be effective in lowering Lp(a) levels in Korean patients in the short term
