4.Updated risk assessments for sudden cardiac death in hypertrophic cardiomyopathy patients with implantable cardioverter-defibrillator
The Korean Journal of Internal Medicine 2023;38(1):7-15
Hypertrophic cardiomyopathy (HCM) is a genetic disease associated with a risk of malignant ventricular tachyarrhythmias and sudden cardiac death (SCD). Assessment of the SCD risk is crucial for its clinical management, and there has been considerable interest in developing risk stratification strategies. An implantable cardioverter-defibrillator (ICD) is a life-saving treatment for patients with HCM who are at a high-risk of ventricular tachyarrhythmias and SCD. However, a substantial number of ICD recipients experience adverse effects arising from inappropriate device therapy and implant-related complications. This has led to numerous investigations of the risk of SCD and the indications for ICD implantation. American guidelines were recently updated to include new risk markers, including left ventricular systolic dysfunction, apical aneurysm, and extensive late gadolinium enhancement, while European guidelines recommend individualized estimated 5-year SCD risk assessment models. Studies evaluating other risk factors for SCD in patients with HCM have also been published. Drawing on recent guidelines and publications on clinical risk factors, we focus this review on updated risk assessments for SCD with ICD therapy in patients with HCM.
5.Residual Cardiovascular Risk Remains Despite of Statin Treatment: Importance of High-Density Lipoprotein Cholesterol.
Korean Journal of Medicine 2011;80(4):397-401
Lowering low-density lipoprotein-cholesterol (LDL-C) is the primary target to prevent cardiovascular events in patients with dyslipidemia at high risk for cardiovascular disease. Many patients on statin therapy have initial or recurrent coronary heart disease events despite reductions in LDL-C. Indeed, 2/3 of patients on statin therapy suffer from residual risk. Low high-density lipoprotein-cholesterol (HDL-C) and high triglycerides levels are modifiable and important factors to resolve a residual risk. Especially, low serum levels of HDL-C (< 40 mg/dL for men, < 50 mg/dL for women) are highly prevalent and are recognized as an independent risk factor for cardiovascular morbidity (myocardial infarction, stroke, peripheral arterial disease, and restenosis after coronary stenting) and mortality. Thus, therapy focusing on raising HDL-C may be an important paradigm for treating and slowing progression of atherosclerosis, coronary heart disease, and co-morbid metabolic disorders. In this review, we discuss the importance of HDL-C based on experimental and large scaled clinical trials.

Therapeutic hypothermia in cardiac arrest patients is associated with favorable outcomes mediated via neuroprotective mechanisms. We report a rare case of a 32-year-old male who demonstrated complete recovery of signal changes on perfusion-weighted imaging after therapeutic hypothermia due to cardiac arrest. Brain MRI with perfusion-weighted imaging, performed three days after ending the hypothermia therapy, showed a marked decrease in relative cerebral blood flow (rCBF) and delay in mean transit time (MTT) in the bilateral basal ganglia, thalami, brain stem, cerebellum, occipitoparietal cortex, and frontotemporal cortex. However, no cerebral ischemia was not noted on diffusion-weighted imaging (DWI) or fluid-attenuated inversion recovery (FLAIR) sequences. A follow-up brain MRI after one week showed complete resolution of the perfusion deficit and the patient was discharged without any neurologic sequelae. The mechanism and interpretation of the perfusion changes in cardiac arrest patients treated with therapeutic hypothermia are discussed.

Journal of the Korean Radiological Society 2018;79(3):175-180
Intracranial chordoma is a rare tumor, originating from embryonic remnants of the primitive notochord. It typically appears as an enhancing extradural midline tumor with bone involvement. We introduce a rare case of a 27-year-old male who had a nonenhancing intradural chordoma showing paramedian location, involving the left cavernous sinus, Meckel's cave, and prepontine cistern. The pathologic diagnosis was confirmed as an intradural chordoma. The imaging findings of this unusual case of a nonenhancing intradural paramedian chordoma will be presented with the differential diagnosis focused on the epidermoid cyst.

BACKGROUND AND OBJECTIVES: Empirical evidence is lacking on the cumulative disease burden of obesity and hypertension and its impact on cardiac function and exercise capacity. The purpose of this study was to determine whether the presence of obesity and hypertension together was associated with cardiac dysfunction and exercise capacity. SUBJECTS AND METHODS: Using a retrospective study design, medical records were reviewed for echocardiographic and treadmill exercise stress test data. Subjects were grouped according to four categories: normal control, obese, hypertensive, or obese and hypertensive. RESULTS: Obese, hypertensive persons showed significantly lower Ea and E/A ratio and greater E/Ea ratio, deceleration time, left ventricular (LV) mass, and LV mass index compared to their counter parts (normal control, obese and/or hypertensive) (all p<0.05), after controlling for age and sex. After controlling for age and sex, significant differences in exercise capacity indices were found, with the obese group having shorter exercise time, lower metabolic equivalents, and lower maximal oxygen uptake than the normal control, hypertensive, or both groups (all p<0.05). The hypertensive or obese and hypertensive group had greater maximal blood pressure compared with the normal control group (all p<0.001). Obese and hypertensive persons were approximately three times more likely to have diastolic dysfunction (odd ratio=2.96, p=0.001), when compared to the reference group (normotensive, non-obese, or hypertensive only persons). CONCLUSION: Diastolic dysfunction was associated with obesity and/or hypertension. The cumulative risk of obesity and hypertension and their impact on diastolic dysfunction which could be modifiable could reduce exercise capacity.

PURPOSE: The purpose of this study was to identify occurrence of needle stick and sharp injuries(NSI) among students, level of faculty stress, and necessity of informed consent when students practice injection skills in fundamentals of nursing practice (FNP). METHODS: Data were collected using self-reporting questionnaires and 74 faculty members who teach FNP responded it. Questionnaires included general characteristics, experiences of NSI, stress level, and informed consent. Data were analyzed using frequency, percent and paired t-test. RESULTS: Of 74 faculty members, 51.4% experienced NSI 3~4 times or more during their FNP classes. Major procedures causing NSI during FNP were ‘ breaking the neck of ampules’, ‘ disposing of used items’, and ‘ inserting needles’. The stress level of faculty was higher and more than doubled when training with human beings compared to manikins. Most faculties (86.5%) agreed to the necessity of informed consent so that the safety of faculty and students could be protected and to provide enough information even though only 10.8% of faculty in this study got informed consent. CONCLUSION: Because there is high risk in every procedure of NSI, faculty has a high level of stress during injection practice in FNS. Therefore, it is necessary to develop a standard NSI precaution program for junior nursing students and discuss informed consent.
