Impact of nutritional index on long-term outcomes of elderly patients with coronary artery disease: sub-analysis of the SHINANO 5 year registry.

Nutritional status is a novel approach to prognostic assessment in patients with cardiovascular disease. However, assessment of nutritional status in elderly patients is challenging due to the significant differences between young patients. The TCBI (Triglycerides × Total cholesterol × Body Weight Index) is a novel and simple nutritional index for predicting long-term outcomes in patients with coronary artery disease. This retrospective study evaluated the efficacy of TCBI in 597 elderly (≥ 75 years) patients enrolled in the SHINANO 5 year registry. The SHINANO 5 year registry, a prospective observational multicenter cohort study, had enrolled 1501 consecutive patients who underwent elective/urgent percutaneous coronary intervention (PCI). In this study, patients were categorized into TCBI quartile groups. The primary endpoints were the occurrence of major adverse cardiac and cerebrovascular events (MACCE), including all-cause death, stroke, and myocardial infarction at 5 year. The mean duration of follow up was 4.3 ± 1.7 years. The average patient age was 80.9 ± 4.3 years. MACCE was observed in 61 (40.9%) patients in the lowest TCBI quartile group. Kaplan-Meier analysis demonstrated an inverse relationship between MACCE and TCBI (log-lank P < 0.001). Multivariate analysis demonstrated that low TCBI significantly predicted the incidence of MACCE (hazard ratio: 1.44, 95% confidence interval: 1.03-2.00; P = 0.031). The TCBI is useful in predicting long-term outcomes in elderly patients undergoing PCI.

The usefulness of brachial-ankle pulse wave velocity in predicting long-term cardiovascular events in younger patients.

Brachial-ankle pulse wave velocity (baPWV) is known as a significant predictor of cardiovascular events. However, the previous studies have not considered age, which can affect the baPWV value. We evaluated the predictive value of baPWV for cardiovascular events in various age groups. From January 2005 to December 2012, all patients admitted to our department with any cardiovascular disease and underwent ankle-brachial index (ABI) measurement were enrolled in the IMPACT-ABI registry. The primary endpoints included major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, and stroke). Of the 3131 patients enrolled, 2554 were included in the analysis, whereas 577 were excluded due to missing baPWV data, ABI ≤0.9 and/or >1.4, and the previous endovascular therapy and/or surgical treatment for peripheral artery disease. Patients were divided according to age 30-59 years (n = 580), 60-69 years (n = 730), 70-79 years (n = 862), and ≥80 years (n = 330). The cumulative incidence of MACE through 5 year was significantly higher in the high baPWV group (>1644 cm/s) than in the low baPWV group (≤1644 cm/s; 8.7 vs. 4.6%; log-rank: p < 0.001). However, among the age groups, only the 30-59-year group showed a significant difference in MACE incidence between those with high and low baPWV (7.0 vs. 0.9%; log-rank: p = 0.001). In conclusion, the baPWV could serve as a useful marker to predict cardiovascular events, particularly among younger patients.

[Multiple hepatic metastases due to germ cell tumor on initial clinical presentation].

A 31-year-old man presented with abdominal pain. Abdominal computed tomography (CT) demonstrated heterogeneously enhanced liver masses and chest CT revealed an anterior abnormal mass. He was admitted for further examination and treatment. The patient's serum beta-HCG level was markedly elevated (2,300ng/ml) and liver biopsy revealed the presence of choriocarcinoma and positive immunostaining for HCG. The patient was suspected to have combined germ cell tumor in the mediastinum with multiple liver metastases. He was treated with 8 cycles of BEP therapy (cisplatin. etoposide, bleomycin) and the beta-HCG level was normalized. We report a case of germ cell tumor with multiple and diffuse hypervascular masses in the liver as the initial clinical manifestation.

Inflammatory Cytokine Levels After Endovascular Therapy in Patients With Peripheral Artery Disease.

We evaluated the impact of endovascular therapy (EVT) on inflammatory cytokine levels and its relationship with in-stent restenosis in patients with peripheral artery disease. The study prospectively enrolled 35 patients with intermittent claudication who underwent EVT of the iliofemoral artery. Levels of interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and tumor necrosis factor α (TNF-α) were measured using enzyme-linked immunosorbent assay before and at 2 hours, 4 hours, and 3 months after EVT. All cytokine levels increased significantly after EVT (IL-6 [pg/mL]: from 1.51 [0.84-1.93] before EVT to 6.97 [4.05-20.41] at 2 hours and 13.29 [4.57-31.88] at 4 hours; MCP-1 [pg/mL]: from 326.65 [265.60-406.55] before EVT to 411.18 [341.21-566.27] at 2 hours and 519.36 [383.58-644.85] at 4 hours; TNF-α [pg/mL]: from 1.08 [0.77-1.29] before EVT to 1.25 [0.94-1.81] at 2 hours and 1.27 [0.95-1.59] at 4 hours, all P < .001). However, cytokine levels did not differ significantly between lesions with and without in-stent restenosis. Overall, our results suggest that EVT significantly increases IL-6, MCP-1, and TNF-α levels in the ischemic leg, but this effect is not associated with a higher rate of in-stent restenosis.

A 2-year follow-up of oxidative stress levels in patients with ST-segment elevation myocardial infarction: a subanalysis of the ALPS-AMI study.

We sought to determine whether serial measurements of oxidative stress levels could serve as a predictive marker for cardiovascular (CV) events in patients with ST-segment elevation myocardial infarction (STEMI). Biological antioxidant potential (BAP) levels were measured at admission and at 6, 12, and 24 months in 69 patients with STEMI. The CV events abruptly increased 6 to 10 months after successful percutaneous coronary intervention in patients with STEMI, and the 6-month BAP levels were significantly lower in patients with CV events (2456 µmol/L [interquartile range: 2237-2615 µmol/L]) than in those without (2849 µmol/L [2575-2987 µmol/L], P < .001). A decreased 6-month BAP level was an independent and significant predictor of long-term CV events (hazard ratio = 2.45; 95% confidence intervals 1.10-5.78; P = .04). Our findings suggest that serial changes in antioxidant capacity, assessed by BAP levels, may serve as a predictive marker for CV events after STEMI.

Clinical Impact of Rapid Reduction of Low-Density Lipoprotein Cholesterol Level on Long-Term Outcome of Acute Myocardial Infarction in the Statin Era: Subanalysis of the ALPS-AMI Study.

BACKGROUND: The optimal period to achieve target percent reduction of low-density lipoprotein cholesterol (LDL-C) level for secondary prevention of acute myocardial infarction (AMI) is not well established. METHODS: The Assessment of Lipophilic vs. Hydrophilic Statin Therapy in AMI (ALPS-AMI) study enrolled 508 patients (mean age, 66.0± 11.6 years; 80.6% male) who were hospitalized for AMI and underwent percutaneous coronary intervention (PCI). Of these patients, 81 were excluded because of the absence of LDL-C measurements at 4 weeks after randomization. In the remaining 427 patients, the target LDL-C level reduction of ≥30% was achieved and not reached within 4 weeks after randomization in 204 cases (early reduction group) and 223 cases (late reduction group). The groups were formed prospectively and analyzed with regard to the composite end point (major adverse cardiovascular event [MACE]: all-cause death, myocardial infarction, and stroke) and clinical outcomes. RESULTS: MACE were significantly more frequent in the late reduction group compared to the early reduction group (9.4% vs. 3.4%, P = 0.013). The incidence of cardiac deaths was also significantly higher in the late reduction group (3.1% vs. 0.5%, P = 0.044). On age-adjusted Cox proportional hazards analysis in statin-naïve patients, percent reduction of LDL-C level during the initial 4 weeks (HR, 0.98; 95% CI: 0.97-0.99, P = 0.042) and baseline LDL-C level (HR, 0.98; 95% CI: 0.97-0.99, P = 0.033) predicted adverse events. CONCLUSIONS: Rapid reduction of LDL-C level is strongly associated with favorable outcome in patients with AMI.

Infective endocarditis associated with mitral valve prolapse in a patient with Klinefelter syndrome.

We herein report a case of infective endocarditis associated with mitral valve prolapse (MVP) in a 34-year-old man with Klinefelter syndrome. The patient was admitted with a fever and headache that had persisted for three weeks. Repeated blood cultures showed growth of Streptococcus oralis. Echocardiography demonstrated severe mitral regurgitation with a large vegetation attached to the prolapsed anterior leaflet. Surgical plasty of the mitral valve was performed because the vegetation measured over 10 mm in diameter and there was a risk of recurrence of embolic complications. This case demonstrates the link between MVP and Klinefelter syndrome and highlights the importance of performing cardiovascular screening and preventing endocarditis.
