BACKGROUND: Left ventricular (LV) remodeling is closely linked to the progression of heart failure. There are limited data on the epidemiology of new onset LV remodeling among elderly women, which requires further investigation. METHOD: We examined data from a community-based cohort of women aged > 65 years, who had received > 2 echocardiography scans from 2009 to 2014. Exclusion criteria for patients included prior echocardiographic evidence of left ventricular enlargement (LVE) or hypertrophy (LVH)...

BACKGROUND: Therapeutic hypothermia (HT) in out-of-hospital cardiac arrest STEMI patients aims to improve their neurological prognosis, but it has been associated with slow coronary flow and cardiac thrombotic events. We sought to serially assess endothelial function during the first 48h after admission in out-of-hospital cardiac arrest STEMI patients, under therapeutic hypothermia (HT). METHODS: From January 2015 to August 2015, eighteen consecutive out-of-hospital cardiac arrest STEMI patients eligible for primary PCI received HT at admission and were included in the study (HT group)...

During blood pressure (BP) measurement, the recommended positioning of the cuff bladder center is directly above the brachial artery. We investigated the relevance of incorrect cuff positioning during (1) auscultatory measurement with an appropriate or improperly small cuff and (2) oscillometric measurement with a wide-range cuff designed to guarantee accurate measurements regardless of position. In subjects with wide BP and arm circumference ranges, (1) auscultatory BP was repeatedly measured with a properly positioned cuff (reference) and, simultaneously, with an identical cuff placed on the other arm in either a correct or an incorrect position (test)...

The early arterial dysfunction linked with obesity and a sedentary lifestyle heightens the likelihood of suffering from future cardiovascular events. Whole-body vibration training (WBVT) may improve systemic arterial stiffness (brachial-ankle pulse wave velocity (baPWV)) and muscle strength in pre- and post-menopausal women. However, the effectiveness of WBVT to impact the arterial segments included in baPWV is unknown. The aim of this study was to investigate the effects of WBVT on aortic and leg arterial stiffness in young sedentary overweight/obese women...

BACKGROUND: In nonhypertensive individuals, lower levels of 25-hydroxyvitamin D (25[OH]D) have been associated with an increased risk of hypertension, and vitamin D deficiency has been associated with endothelial dysfunction in such individuals. However, the effect of vitamin D supplementation on endothelial dysfunction in nonhypertensive individuals has not been examined in a rigorous fashion. METHODS: In this randomized, double-blind, placebo-controlled trial of nonhypertensive, nondiabetic overweight, or obese individuals with vitamin D deficiency (body mass index ≥25 and 25[OH]D ≤ 20 ng/ml), we assigned subjects to receive either ergocalciferol (50,000 units) or matching placebo, once a week for 8 weeks...

BACKGROUND: Peripheral arterial disease (PAD) is a costly source of morbidity and mortality among older persons in the United States. Dietary intake plays a role in the development of atherosclerotic cardiovascular disease; however, few studies have examined the relation of food intake or dietary patterns with PAD. OBJECTIVE: We examined the relation between habitual dietary intake at midlife and incident PAD over ∼20 y of follow-up. DESIGN: Among 14,082 participants enrolled in the ARIC (Atherosclerosis Risk in Communities) Study initially free of PAD, dietary intake was assessed at baseline in 1987-1989 by using a modified Harvard food-frequency questionnaire...

BACKGROUND: The complete resection is one of the most crucial requirements to achieve favorable outcomes in oncologic surgery. The apex of the lung is surrounded complicatedly by the clavicle, the first rib, the subclavian artery and vein, and the brachial plexus. Therefore, the image information especially about the infiltration of adjacent anatomic structures, facilitates the surgery in the apical lung cancer. CASE PRESENTATION: A 70-year-old man presented at our hospital with a computed tomography (CT) scan showing a tumor at the left lung apex that infiltrated the chest wall...

Left ventricular (LV) diastolic dysfunction and subsequent overt heart failure are more prevalent in elderly women. Close interaction between arterial stiffness and LV morphology/function has been reported. The aim of this study was to investigate whether there is an age- and gender-dependent relationship between arterial stiffness and LV diastolic function. A total of 819 subjects (58.6 ± 13.3 years, 50.2% men) without structural heart disease (LV ejection fraction ≥50%) were retrospectively analyzed...

Adrenaline is known to prolong the duration of local anesthesia but its effects on the pharmacokinetic processes of local anesthetic drugs are not fully understood. Our objective was to develop a compartmental model for quantification of adrenaline's impact on the pharmacokinetics of perineurally-injected lidocaine in the dog. Dogs were subjected to paravertebral brachial plexus block using lidocaine alone or adrenalinated lidocaine. Data was collected through a prospective, randomised, blinded crossover protocol performed over three periods...

Specific flavonoid-rich foods/beverages are reported to exert positive effects on vascular function; however, data relating to effects in the postprandial state are limited. The present study investigated the postprandial, time-dependent (0-7 h) impact of citrus flavanone intake on vascular function. An acute, randomised, controlled, double-masked, cross-over intervention study was conducted by including middle-aged healthy men (30-65 years, n 28) to assess the impact of flavanone intake (orange juice: 128·9 mg; flavanone-rich orange juice: 272·1 mg; homogenised whole orange: 452·8 mg; isoenergetic control: 0 mg flavanones) on postprandial (double meal delivering a total of 81 g of fat) endothelial function...

Elevated brachial blood pressure (BP) in childhood tracks into adulthood. Central BP and measures of arterial stiffness, such as aortic augmentation index (AIx) and pulse wave velocity (PWV), have been associated with future cardiovascular disease. This pilot study assessed the feasibility of noninvasively measuring these parameters in preschool children and explored factors that may be associated with elevated BP in this age group. Brachial BP was measured using an electronic oscillometric unit (Dinamap PRO 100) and defined as elevated when systolic BP (SBP) and/or diastolic BP (DBP) was ≥ the 90th percentile for age, gender, and height...

BACKGROUND: There is growing evidence of an interaction between HIV-infection, anti-retroviral therapy (ART) and cardiovascular diseases (CVD). Epidemiological studies in Europe and North America have been observing a shift towards an increased incidence of coronary heart disease and acute myocardial infarctions in HIV-infected populations compared to the general population even after adjusting for traditional cardiovascular risk factors. Despite South Africa (and sub-Saharan Africa, SSA) being regarded as the epicentre of the global HIV epidemic, very little is known about the prevalence of cardiovascular risk factors and precursors of vascular disease in HIV-infected populations in this region...
