This study aims to evaluate the electrophysiological properties of the heart conduction system in patients with unexplained polymorphic ventricular tachycardia (VT) and/or ventricular fibrillation (VF), in patients with specific genetic mutations regarding sudden cardiac death or sudden cardiac arrest, in their family members and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Also a National Dutch registry for patients with unexplained polymorphic VT and/or VF and their family members will be created. By combining the data from the registry and the results of ECGI, The investigators hope to identity risk markers for patients at higher risk for apparently idiopathic ventricular fibrillation, and use these for an adapted flow chart for the 'general'population of patients at risk for unexplained polymorphic VT and/or VF. The investigators aim to be able to identify patients before the first arrhythmic event, and aim for better treatment strategies in the future.
This study evaluates whether addition of the thromboxane receptor antagonist to chronic aspirin therapy improves endothelial function and reduces non-platelet thromboxane generation in patients with established cardiovascular disease. Half of participants will receive ifetroban and the other half will receive matchcing placebo for the 4 week study period.
Annually 13000 Norwegians experience an ischemic stroke. The number of stroke is anticipated to increase with 50% within 2030 due to a growing number of elderly. Many of them will have severe function deficits and reduced quality of life. The investigators have established a cohort consisting of 800 patients with first time ischemic stroke treated at hospitals in Central Norway. The investigators want to study the incidence and prognostic markers for death, recurrent stroke and severe functional deficits during a period of 10 years after the initial ischemic stroke. The investigators want to focus on the impact of physical functioning, the level of physical activity and use of medication for secondary prevention on the incidence of death, recurrent stroke and severe functional deficits. The investigators are especially interested in the importance of fulfilling the treatment targets for blood pressure and cholesterol and the importance of smoking cessation in stroke survivors. Our objective is to improve todays stroke treatment and achieve a more efficient use of the health resources in order to increase survival after stroke maintaining a good physical and psychological function and quality of life.
Epidemiological and clinical evidence suggests that high-dose intake of long-chain n-3 fatty acids have a favorable role in altering blood TG and non-HDL cholesterol when combined with statins in hyperlipidemic patients. Their efficacy in altering low density lipoprotein cholesterol particle size and concentration is yet to be confirmed. This study evaluates the effects of adding 4/day eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) to stable statin therapy on blood TG, non-HDL, LDL-C as well as small dense (sdLDL) particle concentration in a group of hyperlipidemic patients. In this randomized, placebo-controlled, double-blind parallel group study, 44 subjects who were already on statin therapy for > 8 weeks and had non-HDL-C levels above the National Lipid Association Recommendations were randomized into two groups. For 8 weeks, together with their prescribed atorvastatin, the intervention group received 4g/day EPA+DHA (in ethyl ester form) while the control group received 4g/day olive oil (placebo). Baseline measurements of non-HDL-C, TG, TC, HDL-C, LDL-C, VLDL-C and sdLDL were repeated at week 8. Differences in dietary intake were assessed with a weighed 3-day food diary at week 4. Primary outcome measures are the percent change in non-HDL-C and sdLDL particle concentration from baseline to the end.
Cardiovascular disease is the leading cause of death in RA patients. This increased risk may be apparent even before the clinical recognition of RA. The optimal approach for identification of patients with increased CV risk has yet to be fully established and a substantial proportion of RA patients at high risk remain unidentified. Heart failure (HF) has been recently recognized as an important contributory factor to the excess CV mortality associated with RA (more than myocardial ischemia), and RA patients with concomitant HF have twice the risk of CV death compared with patients with RA alone. HF in RA typically presents with occult or atypical clinical symptomatology, tend to be managed less aggressively and have poorer outcomes. For developing effective preventive strategies, the evaluation of patients in early asymptomatic stages is of great importance. The investigators propose to perform an observational longitudinal study (with cases and controls) including RA patients (with and without HF) from a single centre to determine cardiovascular profiles that may be associated with higher risk for developing symptomatic HF and CV events. For this purpose the investigators will use clinical, echocardiographic, serum biomarker, and genetic data
Chronic kidney disease (CKD) affects 8-16% of the world's population, and is independently associated with cardiovascular disease (CVD). As renal function declines, rates of major adverse cardiovascular events, cardiovascular and all-cause mortality increase. In addition to hypertension, increased arterial stiffness is characteristic of CKD, a marker of CVD risk, and an independent predictor of mortality in CKD patients. The endothelium is an important regulator of arterial stiffness, and endothelial dysfunction is a feature of CKD and a predictor of CVD. Current treatment of CKD is limited and aims to reduce blood pressure and proteinuria through the use of angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB). However, many patients still progress to end-stage renal failure and often these patients die as a result of CVD. A novel peptide, apelin, is proposed to be a potential treatment for CKD, with additional cardiovascular benefits. The AlPaCKa study investigators will carry out forearm blood flow and renal clearance studies in 25 patients with CKD and 25 matched healthy volunteers to determine the effects of apelin on cardiovascular and renal parameters. It is hoped apelin will be confirmed as a potential future treatment for CKD.
Health literacy is the ability to access, understand, evaluate and apply information in order to communicate with health professionals and understand health instructions but also, promote, maintain and improve health throughout life. Health literacy (HL) is known as a health determinant. An association has been shown between low HL and poorer health outcomes such as increased number of unscheduled hospitalisation or emergency visits, low medication adherence and poor health status. These have been particularly demonstrated with cardiovascular diseases, which combine risk factors (emergency hospitalization, reduction in the length of hospital stays, and complex secondary preventive drug treatments). Despite large scientific international literature about HL and health outcomes, no information is available in France on the prevalence of low HL level among patients managed for neuro-cardio-vascular diseases. It has been shown in other countries that healthcare professionals overestimate the HL level of their patients and do not adapt information to the HL level. Therefore, patients with low HL do not understand and/or are not able to use properly the information they receive. Having a better knowledge of HL level and characteristics in these patients is necessary to develop tools for helping healthcare professionals to identify patients with low HL level and to realize the role of HL as a determinant of health. It will also provide more precise information on the difficulties or needs of patients with different levels of health literacy.
The present study will investigate the effect of prior walking on postprandial metabolism and endothelial function in centrally obese South Asian and White European men. Participants will complete two, 2-day trials in a random, crossover design separated by at least a week. On day 1, participants will either rest or complete a 60 minute walk at 60% maximal oxygen uptake. On day 2, participants will arrive at 08:00 having fasted overnight and a baseline venous blood sample and endothelial function measurement will be taken. Participants will consume a high-fat breakfast and lunch and 12 subsequent venous blood samples will be taken throughout the day at standardised intervals to measure a variety of coronary heart disease risk markers. A second endothelial function measurement will be completed 2 hours after the breakfast. Blood pressure will be measured every hour. It is expected that the South Asian participants will have impaired metabolism and endothelial function compared to their European counterparts but the bout of exercise performed on day 1 will mitigate these responses.
Women with a history of preeclampsia (PE) have increased risk of hypertension and cardiovascular disease (CVD) later in life. Thus, PE is acknowledged as an independent risk factor for CVD, which is the number one cause of death in women in the western part of the world. Objective: The purpose of this study is to investigate 1) the prevalence of CVD after PE, 2) which women have the highest risk of developing CVD, 3) when early stages of CVD can be detected in women with previous PE and 4) how CVD progress over time. Methods: 1000 women with previous PE between the age of 35-55 years will be invited to participate in a follow-up study consisting of anthropometric measurements, blood pressure measurement, urine- and blood samples, cardiac CT-scan and questionnaires. Coronary atherosclerosis will be evaluated using CT imaging.The women will be compared with women with a formerly uncomplicated pregnancy, Summary: The study will provide new important information to guide future clinical follow-up, and potentially prevent disease and early death in a large group of women with a history of PE.
The Sponsor is developing the test medicine, AZD5718, for the potential treatment of cardiovascular disease. The study is an open-label, single dose study involving 6 healthy male subjects. The volunteers will receive a single dose of 200 mg radiolabelled AZD5718 (14C-AZD5718 Oral Suspension) containing not more than 9.9 MBq of radiocarbon. Volunteers will attend the clinic for 9 days (Day -1 to Day 8) to receive a single dose of the test medicine. It is planned that the volunteers will be discharged as a group once all volunteers have reached the discharge criteria. This may result in the subjects being discharged as a group prior to completion of the planned residency period. If the discharge criteria are not met by volunteers by Day 8, the individual volunteers who have not met the criteria will remain in the clinical unit for a further 48 h (until Day 10). A follow-up call will take place 7 to 10 days after discharge to ensure the ongoing wellbeing of volunteers.
