Background Insulin resistance, decreased response of peripheral tissue to normal insulin levels, is known to be related to cardiometabolic diseases. Cardiopulmonary fitness is also considered to be related to these comorbidities. Therefore, we investigated the relationship between insulin resistance and cardiopulmonary fitness by performing a 3-minute step test in a Korean non-diabetes mellitus (DM) population. Methods A total of 118 non-DM subjects were enrolled during their routine health check-up. Insulin resistance was measured by …

Purpose Weight loss reduces cardiovascular risk factors in the obese. However, weight reduction through diet negatively affects long-term bone health. The aim of study was to determine the ability of combined aerobic and resistance exercise (CE) to reduce weight and cardiovascular risk without diminishing bone health. Methods Twenty-five young adults participated in an 8-week weight loss CE program. Subjects were allocated to an obese group or a control group by body mass index (BMI). Body weight, BMI, body composition …

Hypertension is designated as either essential (primary) hypertension or secondary hypertension and is defined as a consistently elevated blood pressure exceeding 140/90 mmHg. Hypertension is called “the silent killer” because it often causes no symptoms for many years, even decades, until it finally damages certain critical organs. In various causes of hypertension, obesity is an increasing health problem worldwide, and several epidemiological studies have identified a positive association between obesity and an …

Purpose: Compared with symptom-limited cardiopulmonary exercise test (CPET), timed walking tests are cheaper, well-tolerated and simpler alternative for assessing exercise capacity in coronary artery disease (CAD) patients. We developed multivariate models for predicting peak oxygen consumption (VO2peak) from 6-minute walk test (6MWT) distance and peak shuttle walk speed for elderly stable CAD patients. Methods: Fifty-eight CAD patients (72 SD 6 years, 66% men) completed:(1) CPET with expired gas analysis on a cycle …

Extracellular fluid (ECF) is associated with blood pressure, but reports on the status of the ECF volume in hypertension have been inconsistent. The aim of this study was to assess the ECF volume status in hypertensives with regard to body size in a large cohort. We performed a single-center case–control observation study for patients who visited the outpatient hypertension clinic and health examination center. For all eligible participants, we examined the body composition, including fluid compartments, using a noninvasive bioimpedance …

Objective: The accuracy of anthropometric surrogate markers such as the body adiposity index (BAI) and other common indexes like the body mass index (BMI), waist‐to‐hip ratio (WHR) and waist‐to‐height ratio (WHtR) to predict metabolic sequelae is essential for its use in clinical practice. Design and Methods: Thus, we evaluated the strength of BAI and other indexes to relate with anthropometric parameters, adipocytokines, blood lipids, parameters of glucose‐homeostasis and blood pressure in 1,770 patients from the Salzburg …

Objective This study investigated the number of Korean adults who had a normal body mass index (BMI) but high body‐fat percentage (BF%) and determined their increased risk factors for cardiovascular diseases, including high blood pressure, hyperglycemia, and dyslipidemia. Design and Methods This cross‐sectional study was based on 12,386 subjects (6,534 men and 5,852 women), with a normal BMI, between 30 and 49 years of age. Subjects were categorized into two groups by BF%(normal BF% group, BF%< 25 for …

Obesity is a major risk factor for cardiometabolic disease, but the effect of body composition on vascular aging and arterial stiffness remains uncertain. We investigated relationships among body composition, blood pressure, age, and aortic pulse wave velocity in healthy individuals. Pulse wave velocity in the thoracic aorta, an indicator of central arterial stiffness, was measured in 221 volunteers (range, 18–72 years; mean, 40.3±13 years) who had no history of cardiovascular disease using cardiovascular MRI. In univariate analyses, age (r …

Although there is evidence that vitamin D deficiency relates to expression of chronic disease, relationship between vitamin D and cardiovascular disease predictors have not been clearly demon strated in Korean. Our objective was to assess the correlation between vitamin D and the …

Background Abnormal left ventricular (LV) structure and diastolic function are frequently detected in a variety of heart diseases, and insulin resistance has been suggested to be associated with LV diastolic dysfunction (LVDD). The aims of this study were to determine the association between LVDD or LV structure and metabolic syndrome (MetS) or insulin resistance, and whether or not the associations are independent of age, blood pressure, and plasma glucose level. Methods A total of 1599 subjects (1161 men and 398 women), 25–83 …
