Cariovascular

BACKGROUND: Only a few studies that investigated dietary intakes of folate, vitamin B6, and vitamin B12 in relation to cariovascular disease (CVD). This study aimed to assess the association of dietary folate, vitamin B6, and vitamin B12 with CVD in the United States population. METHODS: A cross-sectional analysis of 65,322 adults aged ≥ 20 years who participated in the Third National Health and Nutrition Examination Survey (NHANES III) and NHANES 1999-2018...

OBJECTIVES: We aimed to evaluate the levels of serum lipoprotein a, LP (a), in Jordanian patients with type 2 diabetes mellitus (DM); and to examine its relation to glycemic control, metabolic syndrome (MS) and duration of DM. The LP (a) is considered one of the independent risk factors for coronary artery disease (CAD) in the general population. METHODS: Fasting blood samples were drawn from 51 diabetic patients with type 2 DM and 31 non-diabetic age and sex control subjects...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infects host cells with angiotensin receptors, leading to pneumonia linked to COVID-19. The virus has a double impact on the cardiovascular system, the infection will be more intense if the host has cardiovascular co-morbidities and the virus can cause life-threatening cardiovascular lesions. Therapies associated with COVID-19 may have adverse cardiovascular effects. Therefore, special attention should be given to cardiovascular protection during COVID-19 infection...

BACKGROUND: Obesity increases mortality, and is linked to cardiovascular diseases and metabolic syndrome (MetS). Therefore, the purpose of this study was to analyze the ability of different adiposity indices to identify subjects with MetS among people with intermediate cariovascular risk. MATERIALS AND METHODS: The cross-sectional study involved 2478 subjects, recruited by the MARK study. Adiposity measures: general adiposity by body mass index (BMI), central adiposity by waist-to-height ratio (WHtR), fat mass percent by the Clínica Universidad de Navarra-body adiposity estimator (CUN-BAE), percentage of body fat and of visceral adipose tissue by body roundness index (BRI) and visceral obesity and general adiposity with body shape index (ABSI)...

PURPOSE: Increasing evidence of a link between erectile dysfunction and cardiovascular disease suggests a shared vascular etiology with endothelial dysfunction as a plausible underlying biological mechanism. To our knowledge whether this association is different for large arterial endothelium compared to microvascular endothelium has not yet been established. We investigated the association of erectile dysfunction with macrovascular and microvascular endothelial function. MATERIALS AND METHODS: A sample of 390 men with a mean age of 55...

BACKGROUND/AIM: Silent myocardial ischemia (MI) can be detected in subjects with any symptoms, in patients after myocardial infarction and in coronary patients who have episodes of symptomatic, as well as of silent MI. This study was carried out to evaluate the frequency, characteristics and prognostic significance of silent MI detected in stress echocardiography test in patients after myocardial infarction. METHODS: In 210 patients within three months after myocardial infarction exercise test was performed...

The investigation included the study of 68 kidneys obtained from the persons of different age which died from mechanical asphyxia (control group) and 110 kidneys from the patients which died from cardiovascular failure that developed against a background of an ischemic heart disease, atherosclerosis, hypertension and their combinations. The studies were conducted using the complex of methods, which included macromicroscopic, histological, scanning electron microscopy and morphometry. In the patient group, vessel tortuosity, microvaricosities, contour irregularities and vessel deformations were found...

In spite of the improvement on chemotherapy results in treating testicular cancer and the introduction of adjuvant chemotherapy to node negative (as well as node positive) breast cancer patients, there is still present a wide spectrum of early and late toxic manifestations. The combination of cisplatin, vinblastine and bleomycin given to testicular cancer might result in cariovascular, neurological, gastrointestinal and renal problems. Late effects of cyclophosphamide, methotrexate and 5-fluorouracil given to breast cancer patients might cause obesity, amenorrhea and infertility...

The teratogenicity and developmental toxicity of valproic acid (VPA) was investigated in Sprague-Dawley CD rats at doses of 0, 150, 200, 300, 400, and 600 mg/kg administered by gavage on days 7-18 of gestation. The VPA-600 dose was maternally toxic, causing death in two of four dams. This dose produced 100% embryonic resorption. The VPA-400 dose was maternally toxic in as much as maternal weight gain was reduced, but no deaths occurred. At this dose five of fifteen litters were completely resorbed, and 52% of all embryos were resorbed...

Heart rate and forearm blood flow responses were measured during experimental tasks requiring sensory intake, sensory rejection, and a mixture of the two behaviors. Subjects were 29 college students who had been categorized using Rotter's locus of control scale. Significant increases in both cardiovascular indices were seen in all three tasks; the responses were smaller, however, during sensory intake. Internals showed a differential response of forearm blood flow. In contrast, externals showed a similar vasodiatation across all tasks...

Detailed cardiorespiratory studies were performed in 10 volunteers in whom general anesthesia was induced with thiopental 3 mg/kg and diazepam 0.4 mg/kg.Minimal changes in blood pressure were noted with both agents. Depression of total peripheral resistance lasted in excess of 20 minutes with diazepam but had returned to control levels with thiopental, elevations in cardiac rate and output were most evident and lasted longer with diazepam. In the healthy volunteer induction of anesthesia with diazepam causes alterations in cardiovascular parameters which are more profound than with thiopental...
