Glutamate and Diastolic Function in Patients Undergoing Aortic Valve Repair

HypertrophyLeft Ventricular3 more

Purpose: The effect of intravenous glutamate infusion on myocardial diastolic function and overall hemodynamics were studied in patients undergoing elective aortic valve replacement with severe aortic stenosis and associated left ventricular hypertrophy . Methods: 25 patients will be included in this double-blind randomized placebo-controlled study. Glutamate was administered intravenously immediately after aortic cross-clamp release. The patients receive either a low dose of 30mg kg-1 h-1 (LG-group) or high dose of 60 mg kg-1 h-1 (HG-group) or placebo (P-group) at a rate of 3.3ml kg-1h-1 for 2h. Transesophageal echocardiography (TEE) is used to measure diastolic and systolic ventricular function before sternotomy (T0), and 2h (T2), 3h (T3) and 6h (T4) after release of cross clamp. Additionally routine hemodynamic parameters are measured intraoperatively.

The Effects of Lowering Dialysate Sodium in Hypertensive Hemodialysis Patients

HypertensionArteriosclerosis1 more

Unfavorably high sodium intakes remain prevalent around the world. A negative sodium gradient in hemodialysis treatment results in absolute sodium removal via diffusive transport of sodium from the blood to the dialysate, and it may be a potentially useful tool to improve sodium loading due to excess dietary sodium intake. The purpose of this study is to determine whether a in small negative sodium gradient could improve blood pressure level, arterial stiffness and left ventricular hypertrophy in hypertensive hemodialysis patients, who had been achieving and maintaining their dry weight assessed by bioimpedance spectroscopy.

Left Ventricular HypertrophyInsulin Resistance2 more

Thickening of the heart muscle (left ventricle) known medically as Left Ventricular Hypertrophy (LVH) is very common in patients with heart disease. This increases risk of cerebrovascular/cardiovascular event. LVH is asymptomatic and managed by the use of medication to control blood pressure, however LVH may be seen in normotensive patients where factors such as obesity and insulin resistance are present. Insulin resistance is a condition where although the body produces insulin it is unable to utilize it effectively. Metformin, a drug used to treat diabetes, can reduce insulin resistance and cause weight loss, it may therefore improve LVH. This study will investigate the ability of metformin to reduce LVH in patients with heart disease, this may be a novel way forward in the risk reduction of cerebrovascular/cardiovascular events. Participants will be identified throughout NHS Tayside, those eligible will be randomly allocated to either metformin or a dummy medication (placebo) and will receive one year of treatment. At the beginning of the study, the thickness of the heart muscle will be measured by ultrasound scan and cardiac Magnetic Resonance Imaging (cMRI). We will also perform non-invasive tests to measure blood vessel function. These tests will be repeated after one year. At the end of the study, we will investigate the difference between placebo treatment and metformin treatment. This study is funded by the British Heart Foundation.

Reduction of Left Ventricular Hypertrophy After Eplerenone Therapy

Hypertension,EssentialObstructive Sleep Apnea1 more

Obstructive sleep apnea syndrome (OSA) is the most frequent sleep disorder characterized by excessive decrease in muscle tone of the soft palate, the tongue and the posterior pharyngeal wall. It leads to airway collapse. In cases of decreased airway passage hypoventilation (hypopnea) occurs while periodic lack of airflow is called apnea. An obstructive sleep apnea syndrome is recognized as an independent cardiovascular risk factor. OSA is very common in patients with resistant hypertension. RAH is diagnosed when blood pressure remains elevated despite simultaneous use of 3 antihypertensive agents from different groups of drugs at optimal to maximum doses, including a diuretic. In patients with OSA frequent episodes of hypoxemia during sleep result in the repeated activation of the sympathetic nervous system. What is more, the episodes of respiratory disorders increases in levels of aldosterone serum concentration with following sodium and water retention and elevation of blood pressure finally. An increased aldosterone level also stimulates synthesis of collagen, promotes stiffening of the arterial wall, myocardial fibrosis with heart muscle remodeling and takes part in development of left ventricular hypertrophy (LVH) - common complication of hypertensive patients with OSA. Several studies, including the Sleep Heart Health Study have confirmed that severe OSA is associated with high prevalence of concentric hypertrophy through sympathetic activation and vasoconstriction. Eplerenone is a selective mineralocorticoid receptor inhibitor. It has no affinity for glucocorticoid, progesterone and androgen receptors and therefore has lower risk of side effects. Eplerenone lowers blood pressure and inhibits heart muscle fibrosis. The hypotensive effect is caused by reduction of fluid retention. Probably, in patients with OSA, a reduction of fluid accumulation especially at the level of the neck may contribute to lowering the resistance in the upper respiratory tract and in that way it may help to decrease the severity of OSA. As LVH remains a strong and independent predictor of total mortality and death from cardiovascular causes, in this study we want to assess whether the addition of Eplerenone to a standard antihypertensive therapy will favorably change left ventricular geometry. We also want to check if the addition the Eplerenone to a standard antihypertensive therapy could be an effective therapeutic option for patients with OSA and RAH.
