1.The Potential Role of Biomarkers Associated with ASCVD Risk: Risk-Enhancing Biomarkers
Journal of Lipid and Atherosclerosis 2019;8(2):173-182
Serum cholesterol is major risk factor and contributor to atherosclerotic cardiovascular disease (ASCVD). Therapeutic cholesterol-lowering drugs, especially statin, revealed that reduction in low-density lipoprotein cholesterol (LDL-C) produces marked reduction of ASCVD events. In the preventive scope, lower LDL-C is generally accepted as better in proven ASCVD patients and high-risk patient groups. However, in patients with low to intermediate risk without ASCVD, risk assessment is clinically guided by traditional major risk factors. In this group, the complement approach to detailed risk assessment about traditional major risk factors is needed. These non-traditional risk factors include ankle-brachial index (ABI), high-sensitivity C-reactive protein (hsCRP) level, lipoprotein(a) (Lp[a]), apolipoprotein B (apoB), or coronary artery calcium (CAC) score. CAC measurements have an additive role in the decision to use statin therapy in non-diabetic patients 40–75 years old with intermediate risk in primary prevention. This review comprises ASCVD lipid/biomarkers other than CAC. The 2013 and 2018 American College of Cardiology/American Heart Association (ACC/AHA) guidelines suggest these factors as risk-enhancing factors to help health care providers better determine individualized risk and treatment options especially regarding abnormal biomarkers. The recent 2018 Korean guidelines for management of dyslipidemia did not include these biomarkers in clinical decision making. The current review describes the current roles of hsCRP, ABI, LP(a), and apoB in personal modulation and management of health based on the 2018 ACC/AHA guideline on the management of blood cholesterol.

2.Acute Heart Failure and Its Management
Journal of Neurocritical Care 2018;11(1):13-22
The prevalence of heart failure (HF) is rapidly increasing throughout the world, and is closely associated with serious morbidity and mortality. In particular, acute HF is one of the main causes of hospitalization and mortality, especially in elderly individuals. In Korea, the socioeconomic burden of HF is substantial. Because of this, the Korean HF society developed chronic and acute HF management guidelines in 2017, adapted process while including as much data from Korean studies as possible. The scope of the current review, which is based on the Korean HF guidelines, includes the definition, diagnosis, and treatment of acute HF with reduced or preserved ejection fractions of various etiologies.

OBJECTIVE: To observe the contrast spreading patterns in the retrodiscal (RD) approach for transforaminal epidural steroid injections and their effect on pain reduction. METHOD: Patients with L5 radiculopathy who were scheduled to receive lumbar TF-EPB were consecutively included. We randomly divided them into the L4-5 RD and L5-S1 RD groups and administered 1 cc of contrast dye into epidural space. We observed the shape and the location of contrast dye on the anterior-posterior and lateral views. We injected 1 cc of 0.5% lidocaine mixed with 20 mg of triamcinolone, and checked the pain intensity before and two weeks after the procedure by using visual analogue scale (VAS). RESULTS: In the L4-5 RD group (n=30), contrast spread over the L4 nerve root in 27 cases and the L4 and L5 nerve roots in 3 cases. In the L5-S1 RD group (n=33), contrast spread over the L5 nerve root in 20 cases, the S1 nerve root in 3 cases, and the L5 and the S1 nerve roots in 10 cases. The contrast spreading patterns could be divided into 4 patterns: the proximal root in 40 cases, the distal root in 19 cases, the anterior epidural space in 3 cases and an undefined pattern in 1 case. CONCLUSION: In RD lumbar TF-EPB, the contrast dye mostly went into the cephalic root and about 60% spread over the proximal nerve root. There was less pain reduction when the contrast dye spread over the distal nerve root.

Myocardial infarction (MI) and stroke often share the same risk factors and pathogenic mechanism. Sometimes they can occur in the same patient proximately, occurring days or weeks apart. However, the simultaneous occurrence of MI and stroke is rare and presents a diagnostic and therapeutic challenge. Specifically, an acute stroke can alter typical features of MI. Thus, recognition of the coexistence of these two events requires a high threshold of suspicion. The authors describe two patients who presented with simultaneous stroke and MI development. The two events developed on the same day in both patients. The second patient did not have chest pain, whereas chest symptoms could not be assessed in the first patient secondary to altered mental status. After the diagnoses were made using clinical and laboratory findings, urgent percutaneous coronary intervention was performed in both patients.

PURPOSE: Hybrid therapy with catheter ablation of the cavo-tricuspid isthmus (CTI) and continuation of anti-arrhythmic drugs (AAD), or electrical cardioversion with AADs might be alternative treatments for patients with persistent atrial fibrillation (AF). The goal of study was to assess the long term success rate of hybrid therapy for persistent AF compared to antiarrhythmic medication therapy after electrical cardioversion and identify the independent risk factors associated with recurrence after hybrid therapy. MATERIALS AND METHODS: A total of 32 patients with persistent AF who developed atrial flutter after the administration of a class Ic or III anti-arrhythmic drug were enrolled. This group was compared with a group (33 patients) who underwent cardioversion and received direct current cardioversion with AADs. Baseline data were collected, and electrocardiogram and symptom driven Holter monitoring were performed every 2-4 months. RESULTS: There was no significant difference in the baseline characteristics between the groups. The 12 month atrial arrhythmia free survival was better in the hybrid group, 49.0% vs. 33.1%, p=0.048. However, during a mean 55.7+/-43.0 months of follow up, the improved survival rate regressed (p=0.25). A larger left atrium size was an independent risk factor for the recurrence of AF after adjusting for confounding factors. CONCLUSION: Despite favorable outcome during 12 month, the CTI block with AADs showed outcomes similar to AAD therapy after electrical cardioversion over a 12 month follow up period. Minimal substrate modification with AADs might be an alternative treatment for persistent AF with minimal atrial remodeling.

BACKGROUND: Nitrous oxide (N2O) is much cheaper than recently introduced volatile anesthetics such as sevoflurane and desflurane, and can reduce the consumption of these anesthetics. The use of N₂O is under current debate. The purpose of this study was to evaluate economic effect of 50% N₂O during sevoflurane anesthesia in Korea. METHODS: Seventy patients were randomly allocated to Group A or Group N. Anesthesia induction was performed using propofol, rocuronium, and 3–5% of sevoflurane with air (Group A) or 50% N2O (Group N). Fresh gas flow (FGF) was 6 L/min during induction, and 3 L/min for maintenance. Mean arterial pressure (MAP), heart rate (HR), bispectral index (BIS), and minimum alveolar concentration (MAC) were recorded. The consumption of sevoflurane was measured at every 10 minutes for the first 1 hour. The economic effect was analyzed based on the payment criterion of Korean National Health Insurance Service. RESULTS: MAP, HR, BIS, and MAC showed no differences between the two groups. The sevoflurane consumptions for the first 1 hour were 39.2 ± 6.3 ml in Group A and 29.2 ± 4.9 ml in Group N (P < 0.01); and the N₂O consumption was 93.7 ± 1.5 L in Group N. The total costs of inhaled anesthetics were 16,190 (14.8 USD) and 13,062 (12.0 USD) Korean won for the first 1 hour in Groups A and N, respectively. CONCLUSIONS: Use of 50% N₂O with 3 L/min FGF reduced the sevoflurane consumption by 25% and anesthetic cost by 20% for the first 1 hour.

BACKGROUND/AIMS: In the bare-metal stent era, routine follow-up coronary angiography (RFU CAG) was used to ensure stent patency. With the advent of drug-eluting stents (DESs) with better safety and efficacy profiles, RFU CAG has been performed less often. There are few data on the clinical impact of RFU CAG after second- or third-generation DES implantation in clinically stable patients with coronary artery disease; the aim of this study was to examine this issue. METHODS: We analyzed clinical outcomes retrospectively of 259 patients who were event-free at 12-month after stent implantation and did not undergo RFU CAG (clinical follow-up group) and 364 patients who were event-free prior to RFU CAG (angiographic follow-up group). Baseline characteristics were compared between the groups. RESULTS: The Kaplan-Meier estimated total survival and major adverse cardiac event (MACE)-free survival did not differ between the groups (p = 0.100 and p = 0.461, respectively). The cumulative MACE rate was also not different between the groups (hazard ratio, 0.85; 95% confidence interval, 0.35 to 2.02). In the angiographic follow-up group, 8.8% revascularization was seen at RFU CAG. CONCLUSIONS: RFU CAG did not affect long-term clinical outcome after second- or third-generation DES implantation in clinically stable patients.

A 57-year-old female with lumbar spinal stenosis at L4-S1 was scheduled to undergo posterolateral interbody fusion. Intubation with a 7.0 size ID cuffed reinforced tracheal tube (Mallinckrodt(TM), Mallinckrodt Medical Atholen, Ireland) was uncomplicated, and any air leakage was not detected at that time. Two hours after the start of operation, an air leak was apparent at the trachea during ventilation in the prone position. Closer inspection of the inflation tube and pilot balloon showed that the pilot balloon had become detached. Because she was being operated on in the prone position, and ventilation was only possible at a less than optimal state, we attempted to fix this without having to reintubate the patient's trachea. Our solution involved inserting a 21-gauge needle into the inflation tube and a handheld aneroid manometer was then connected to it. The tube cuff was thereafter inflated up to a pressure of 20 cmH2O. In conclusion, careful manipulation is recommended when performing intubation and a needle connector may help secure the airway if the pilot balloon becomes detached during the procedure.

PURPOSE: The purpose of this study was to assess the potential benefit of a 5-hydroxytryptamine receptor antagonist, sarpogrelate-based triple antiplatelet therapy (TAPT) in comparison with dual antiplatelet therapy (DAPT) in patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). MATERIALS AND METHODS: 119 patients of STEMI were retrospectively assessed. All patients received aspirin and clopidogrel per standard of care. Among them, 53 patients received an additional loading dose of sarpogrelate and a maintenance dose for 6 months post-PCI (TAPT group), while others did not (DAPT group). RESULTS: The rates of complete ST-segment resolution at 30 minutes post-PCI and post-procedural thrombolysis in myocardial infarction flow were not significantly different between the two groups (52.8% vs. 48.5%, p=0.200; 92.5% vs. 89.4%, p=0.080). In addition, no significant differences were observed between the two groups with regard to 30-day and 12-month clinical outcomes (cardiac death, myocardial infarction, stent thrombosis, target vessel revascularization, and severe bleeding). Meanwhile, improvement in left ventricular (LV) systolic function was observed in the TAPT group [ΔLV ejection fraction (LVEF)=17.1±9.4%, p<0.001; Δglobal longitudinal strain (GLS)=−9.4±4.2% , p<0.001] at 6 months, whereas it was not in the DAPT group (ΔLVEF= 8.8±6.5%, p=0.090; ΔGLS=−4.6±3.4%, p=0.106). In multivariate analyses, TAPT was an independent predictor for LV functional recovery (odds ratio, 2.61; 95% confidence interval, 1.16–5.87; p=0.003). CONCLUSION: Sarpogrelate-based TAPT improved LV systolic function at 6 months in STEMI patients undergoing primary PCI.
