Cardiovascular disorders

Condensed Abstract: The prevalence and prognostic importance of CM occurring as a consequence of AF is poorly defined. This study investigated the incidence of CM in patients with AF, its clinical features and long-term outcomes. We demonstrated that CM is common in patients presenting acutely with newly diagnosed rapid AF,...

Loop diuretics are currently recommended by scientific societies and associations of cardiology for treatment of symptoms of heart failure. Furosemide, which belongs to this pharmacological group, is the most commonly used in this disease. Torasemide prolonged-release is an equally effective alternative to furosemide for that purpose, although it is thought...

Improvements in multislice computed tomography (MSCT) angiography of the coronary vessels have enabled the minimally invasive detection of coronary artery stenoses, while quantitative coronary angiography (QCA) is the accepted reference standard for evaluation thereof. Sixteen-slice MSCT showed promising diagnostic accuracy in detecting coronary artery stenoses haemodynamically and the subsequent introduction...

The goal of the present correlational study is to test the hypothesis that anger initiates essential hypertension in Canadian Caucasian adults with a family history of hypertension. The study population will include a cohort of 100 men and women aged 25 to 45 years at enrollment recruited from the University...

Endothelin (ET) is an important modulator of renal function through its binding to ETA and ETB receptors in renal tissue. Various renal cells have the ability to synthesize and release endothelin-1 and elevated plasma and urinary endothelin levels have been measured in patients with chronic kidney diseases. Within the last...

Lung perfusion/ventilation was introduced as a means to minimize cardiopulmonary (CPB)-related pulmonary ischemic injury. Current results in the literature are divergent, and the role of gas exchange during lung perfusion/ventilation during CPB, remains undefined. This report details a) the technique of continuous lung perfusion/ventilation during CPB, b) provides initial observations,...

Background: Statins are recommended as first line therapy for the prevention of cardiovascular disease. Some individuals are statin intolerant or may need additional cholesterol lowering to achieve their cholesterol targets. Purpose: To review the pharmacology, clinical efficacy and safety of colesevelam mono- and combination therapy in patients with hypercholesterolemia. Data source: English-language...

Aldosterone blockade has been shown to be effective in reducing total mortality in patients with severe heart failure due to systolic left ventricular dysfunction and in patients with heart failure post myocardial infarction. Increasing evidence suggests that aldosterone blockade alone and or in conjunction with an angiotensin converting enzyme inhibitor...

Calcified aortic valve disease is a slowly progressive disorder that ranges from mild valve thickening with no obstruction of blood flow, known as aortic sclerosis, to severe calcification with impaired leaflet motion or aortic stenosis. In the present work we describe a rapid, reproducible and effective method to carry out...

Familial hypercholesterolemia is a genetic disorder caused by a mutation in the low density lipoprotein (LDL) receptor gene. The homozygous type of the disease is rare and causes tendon xanthomas and coronary artery disease during the early years of life. Premature coronary artery occlusive disease in familial homozygous hypercholesterolemia might...

Acute coronary syndrome (ACS) in pregnancy has traditionally been considered to be a rare event, but the combination of normal physiological changes of pregnancy and more prevalent cardiovascular risk factors are increasing its incidence in this population. The present report describes a 39 year-old woman that is seven weeks pregnant...

OWR is a genetic disease, transmitted as an autosomal dominant disorder characterized by arteriovenous malformations pre-dominantly involving the mucocutaneous epithelium. One of the significant complications is the development of arteriovenous fistulas in different organs like the liver and brain. One of the rarest complications of this arteriovenous conduit is a...

We experienced a successful surgical Williams’s syndrome case of extended aortoplasty by means of Doty’s method (two sinus reconstructions) for congenital supravalvular aortic stenosis. Case was 29-year-old woman, who had no complaint except heart murmur and dyspnea. The retrograde aortography and Digital Subtraction Angiography (DSA) demonstrated localized stenosis just above...

Objective: Earlier studies have reported that a decrease in exercise capacity might indicate endothelial dysfunction. However, the effects of improvement of endothelial functions on exercise capacity have not been evaluated. The aim of the present study is to investigate the effects of nebivolol on flow-mediated dilatation (FMD), and on the...

Objectives: There is an established causal link between obesity and cardiovascular outcomes. The aim of this review was to determine whether an independent relationship exists between anthropometric measurements of weight (typically body mass index [BMI]) and cardiovascular outcomes (e.g. angina, myocardial infarction, congestive heart failure, stroke, and mortality due to...

Hypertension is the leading cause of disability and cardiovascular mortality world-wide. Approximately one-third of the US adult population and over a billion people world-wide have hypertension. Despite increased awareness of hypertension and availability of many effective antihypertensive agents, only one third of patients achieve their target blood pressure (BP). All...

Pitavastatin is an HMG-CoA reductase inhibitor that significantly reduces the plasma levels of total cholesterol, LDL-C and triglycerides, while also causing modest elevation of the plasma high-density cholesterol (HDL-C) level. This statin is minimally metabolized by the cytochrome P-450 (CYP) isozymes; it is glucuronized and converted to the inactive lactone...

Prevention is better than cure best applies here. As per many authors, posterior leaflet chordae preservation prevent Left ventricular rupture (LVR) and preserve LV geometry. We are presenting here 5 types of left ventricular rupture (LVR) post Mitral valve replacement (MVR) with different methods to repair with the advantages and...

The renin-angiotensin system can be inhibited through inhibition of angiotensin I generation from angiotensinogen by direct renin inhibitors, inhibition of angiotensin II generation from angiotensin I by angiotensin-converting enzyme inhibitors and by direct inhibition of the action of angiotensin II receptor level. Aliskiren, the first direct renin inhibitor to reach...

Background: Due to the rise in the number of reports of stress cardiomyopathy in the literature, awareness of this condition is increasing. Although different names have been used to describe this condition, the similarities in clinical, electrocardiographic, echocardiographic, and angiographic features suggest that they represent the same spectrum of diseases...

Hypertension can lead to significant morbidity and mortality, and requires lifestyle modifications with or without drug therapy to achieve target blood pressure control. Various classes of anti-hypertensive medications are available to healthcare providers. Choice of medications is based not only on efficacy but also tolerability and cost. Aliskiren is the...

Aspirin and clopidogrel are the most commonly used antiplatelet agents in patients with coronary artery disease. The existence of resistance to these agents has been a controversial issue and new drugs are being developed to overcome this problem. Laboratory tests, which can identify resistance and correlate this with clinical outcome,...

Several clinical studies demonstrate a beneficial role of angiotensin-converting enzyme (ACE) inhibitors in patients with myocardial infarction, hypertension and diabetes mellitus. This review focuses on the effects of ramipril, a weak inhibitor of ACE that is rapidly hydrolyzed to ramiprilat, an active metabolite. The Heart Outcome Prevention Evaluation (HOPE) study...

Once used only as third-line therapy in the management of chronic pain states, methadone is now being used as first- and second-line therapy. Most risks and the stigma associated with methadone use have been known for years. Only over the past decade or so have the unique pharmacokinetic-pharmacodynamic properties and...

Suppression of the Renin-Angiotensin-Aldosterone system (RAAS) is an established intervention in the management of cardiovascular disease. Large, randomized controlled trials have provided a sound evidence base for the use of mineralocorticoid receptor antagonists to block the end product of the RAAS in the treatment of heart failure. However, the place...

Antiplatelet therapy is the cornerstone in the modern therapy of patients with acute coronary syndromes (ACS), because of the unique role of platelets in coronary thrombosis. Clopidogrel in combination with aspirin is the current “gold standard” for reducing cardiovascular events in such patients, providing a synergistic platelet inhibition through different...

Chronic stable angina pectoris results from a fixed coronary arterial obstruction causing an imbalance between myocardial oxygen supply and demand. Current therapy aims to reduce cardiovascular events (vasculoprotective) thereby improving survival, and/or relieve ischemic symptoms (antianginal) thereby improving the quality of life. Vasculoprotective therapy consists of lifestyle modification, antiplatelet agents,...
