Filter by:The RITMO (Registro Italiano sul trattamento del Tronco coMune non protettO) observational study will appraise the prevalence, management strategy, and prognosis of unprotected left main coronary artery disease in Italy.
The purpose of the study was to investigate the dose-response effect of increasing doses of Bifidobacterium animalis ssp lactis (BB-12) and Lactobacillus paracasei ssp paracasei (CRL-431) on the immune response, blood lipids, gut microflora, recovery from feces and overall tolerance in healthy young adults.
The primary objective is to show superiority in survival of the modified method with the LUCAS Chest Compression System, compared to the conventional manual resuscitation method in patients suffering from out of hospital sudden cardiac arrest.
The objective of this trial is to examine the long-term effects of a diet low in carbohydrates, as compared to one low in fat, on cardiovascular disease risk factors, including blood pressure (BP), body weight and composition, serum lipids, plasma glucose, insulin, adipocytokines (adiponectin, leptin, resistin), and C-reactive protein (CRP) among obese adults. The investigators will test the following hypotheses: Hypothesis 1: Compared to a low fat diet, a diet low in carbohydrates will reduce systolic and diastolic BP over 12 months; Hypothesis 2: Compared to a low fat diet, a diet low in carbohydrates will reduce body weight, total percent body fat, and waist circumference over 12 months; Hypothesis 3: Compared to a low fat diet, a diet low in carbohydrates will reduce serum levels of LDL-cholesterol and triglycerides and increase serum levels of HDL-cholesterol over 12 months; Hypothesis 4: Compared to a low fat diet, a diet low in carbohydrates will reduce plasma levels of glucose and insulin levels over 12 months; and Hypothesis 5: Compared to a low fat diet, a diet low in carbohydrates will reduce plasma levels of leptin, resistin, and CRP and increase plasma levels of adiponectin over 12 months.
Cardiovascular disease (CVD) is a serious health concern for American Indians, but there have been few behaviorally based programs to lessen CVD risk among this population. The purpose of this study is to evaluate whether a Web-based program, in addition to usual medical care, can lower CVD risk factors among American Indians who have type 2 diabetes and a high risk of developing CVD.
Cardiovascular disease (CVD) and diabetes are health conditions that are strongly influenced by a person's diet. Although the best diet to prevent CVD and diabetes is uncertain, reducing intake of saturated and transunsaturated fats is known to help lower cardiovascular risk. However, even diets low in these fats can vary widely in other energy providing nutrients, particularly carbohydrates. This study will determine the effects of a higher versus lower carbohydrate diet, each with a high or low glycemic index (GI) composition, on risk factors for CVD and diabetes.
Sleep-disordered breathing (SDB) is a condition in which a person experiences frequent breathing pauses during sleep, also known as sleep apnea. There is evidence that the recurrent sleep arousal and associated shortage of oxygen in the body may increase risk for cardiovascular disease (CVD). It is believed that treatment with continuous positive airway pressure (CPAP) may reduce certain risk factors for heart disease, including markers of inflammation and oxidative stress. This study will evaluate the effectiveness of CPAP in reducing CVD risk factors in people with SDB.
The purpose of this study was to determine whether computer-driven protocolized weaning is superior to physician-directed non-protocolized weaning in over-24-hours-ventilated surgical intensive care unit (ICU) patients. The main hypothesis was that weaning duration differs between both methods. Secondary hypotheses were that reintubation rate, duration of mechanical ventilation, intensive care unit (ICU) length of stay and workload for physicians and nurses differ between both methods.
The purpose of this study is to determine, with Positron Emission Tomography (PET), the role of nitric oxide in the age-associated effect on fatty acid and glucose delivery on myocardial substrate metabolism.
Cardiovascular is a major cause of mortality in Iran, accounting for 45.7% of deaths. In Golestan (North Eastern Iran) preliminary findings from follow-up of the Golestan Cohort are consistent with national figures: with 45% (at least 22 of 48 deaths) of all deaths attributed to cardiovascular events. Cardiovascular diseases will become an increasing problem as the Iranian population ages. In 2003 Law and Wald proposed prevention of cardiovascular disease using fixed-dose combination therapy combining antihypertensive, lipid lowering and antiplatelet drugs in a single preparation. They proposed that this treatment should be offered to all persons at high risk of cardiovascular disease whether or not they have elevated blood pressure or elevated serum lipid concentrations. This pilot study aims to investigate the safety and efficacy of fixed-dose combination therapy with two antihypertensive drugs, aspirin and atorvastatin in a population who would not currently be considered eligible for antihypertensive treatment or for lipid lowering treatment. Methods: This is a double-blind randomized controlled trial. The intervention group will be assigned to take a tablet consisting of a single daily tablet comprising Aspirin 81mg, Hydrochlorothiazide 12.5mg, Enalapril 2.5mg and Atorvastatin 20mg. The control group will be assigned to an identical placebo. The population studied includes men aged 50 to 80 (inclusive) and women aged 55 to 80 (inclusive) who are currently not eligible for or taking antihypertensive or lipid lowering therapy. Persons who are found at baseline to have blood pressure >160/100 mm Hg, total cholesterol >240mg/dL, existing cardiovascular disease or to be taking antihypertensive ore lipid lowering therapy are excluded. It is intended to randomize and follow up 500 subjects for 12 months. The primary outcome for the purpose of sample size calculation is change in systolic blood pressure. Additional outcomes include change in diastolic blood pressure, change in LDL cholesterol and occurrence of adverse events.
