Filter by:Cardiovascular disease is the most common cause of death in the world. Most of the attention in treating ischemic heart disease (IHD) is understandably directed toward treating coronary artery disease. However there are other treatable culprits in these patients. Left ventricular hypertrophy (LVH) is widespread in IHD patients, even in the absence of hypertension. It is a strong predictor of cardiovascular events and all-cause mortality. In one study, the presence of LVH was a stronger predictor of mortality than either multivessel cor-onary disease or impaired LV function. Metformin is an antihyperglycemic agent with a history of successful use in type 2 diabetes. In the UKPDS (United Kingdom Prospective Diabetes Study), metformin was associated with a 39% lower risk of myocardial infarction compared with conventional therapy. Metformin also offered dual benefits of improving vascular function and lessening ischemia in nondiabetic patients. Hence, the main aim of this study was to assess whether metformin could regress LVM in patients with IHD. The secondary aim was to assess the effect of metformin on LV volumes and endothelial function in this patient group.
Out-patients with coronary heart disease or hypertension will fill out a depression screening questionnaire while waiting in a cardiac clinic. Using a randomised-controlled study design half of the patients will receive a patient-targeted written screening feedback. This feedback contains information about depression in general, depression-severity adapted treatment guidelines and contact-information for treatment. Patients in the control group receive no direct screening-feedback but their cardiologist will be informed about the screening result. All patients with a positive screening-result will be contacted after one month and six months and asked for symptoms of depression, and their use of health care. The aim of this study is to evaluate the efficiency of this minimal intervention on the course of depressive symptom in patients with known coronary heart disease or hypertension.
The aim of this study is to evaluate the effects of N-acetyl cysteine on periprocedural myocardial infarction and major cardiac and cerebral events in patients undergoing percutaneous coronary intervention and who have moderate to high risk for contrast induced nephropathy.
In a previous study, the investigators delivered graphs to family physicians that outlined the proportion of patients with a history of diabetes or heart disease achieving evidence-based quality targets derived from guideline recommendations. A qualitative evaluation found that participating family physicians did not act upon the feedback for two main reasons. First, they felt that targets recommended in guidelines often did not apply for particular patients. Second, they complained that had difficulty using the feedback reports that only provided aggregate level data for clinical action. In this cluster-randomized trial, the investigators test two approaches to conducting audit and feedback that aims to address these issues. The investigators hypothesize that feedback identifying a small number of patients at high-risk for cardiovascular events requiring action will more effectively lead to changes in clinical behavior than feedback identifying all patients not reaching optimal care targets.
The specific aim of this study is to assess whether a device approved by the FDA to measure pulse oximetry can accurately estimate cardiac output.
The purpose of this study is to assess the effectiveness and safety of rivaroxaban compared with placebo (inactive medication), in reducing the risk of death, myocardial infarction or stroke in participants with heart failure and significant coronary artery disease following an episode of decompensated heart failure.
Little is known on the prevalence of sleep disorders and their role in the increased prevalence of cardiovascular diseases in the developing world. We To assess the prevalence of major sleep disorders in a rural South American population, and to determine whether these conditions are associated with a poor cardiovascular health or with the occurrence of stroke or ischemic heart disease. This is a three-phase, population-based, door-to-door survey in Atahualpa. During phase I, all residents aged ≥40 years will be screened with validated Spanish versions of five questionnaires to evaluate major sleep disorders. In phase II, neurologists will examine persons suspected of having a sleep disorder and a random sample of negative individuals to assess the prevalence of these conditions and to validate the accuracy of questionnaires. In phase III, patients with a confirmed sleep disorder will undergo nocturnal polysomnography for achieving a more specific diagnosis. The occurrence of sleep disorders will be correlated with the cardiovascular health of the population as well as with the presence of stroke and ischemic heart disease. This epidemiological study may prove cost-effective in improving sleep conditions of people living in rural areas of developing countries, and may be used as a model for the evaluation of sleep disorders and their cardiovascular correlates in these populations.
Cardiovascular complications account for the highest mortality in type 2 diabetic patients, mainly due to coronary artery disease (CAD). Most of the attention in treating CAD in type 2 diabetes is understandably directed toward treating coronary artery conditions. However there are other treatable culprits in these patients. Left ventricular hypertrophy (LVH) is widespread in type 2 diabetic patients with CAD, even in the absence of hypertension. It is a strong predictor of cardiovascular events and all-cause mortality. Regression of LVH has been associated with an improved prognosis, independent of change in blood pressure (BP). Therefore, cardiovascular events and mortality in type 2 diabetes with CAD might will be reduced if the investigators can find novel therapies to regress LVH. Alpha-lipoic acid reduces oxidative stress which then regresses LVH. Alpha-lipoic acid can improve endothelial function in diabetic conditions. Hence, the main aim of this study was to assess whether alpha-lipoic acid could regress LVM in type 2 diabetic patients with CAD.
The purpose of this study is to examine the improvement of myocardial blood flow induced by regained vasomotor functions of the stented coronary segment after resorption of BVS over time.
The primary objective of this project is to demonstrate that a new approach to cardiac stress imaging that combines treadmill exercise with cardiac magnetic resonance (CMR) provides valuable clinical information in a cost-effective manner.
