Prevention of heart failure.

Purpose Of Review: Chronic heart failure imposes a significant health burden and remains a substantial and increasing problem despite advances in therapy. Hence, prevention of heart failure is a priority.

Recent Findings: Various risk factors have been identified that contribute to the development of heart failure.

Pleuropericarditis and pericardial tamponade associated with inflammatory bowel disease.

Extraintestinal manifestations have been described with inflammatory bowel disease (IBD). Cardiac involvement in IBD is rare and may present as pericardial effusion, myopericarditis and conduction defects. Here we present a case of IBD with asymptomatic pericardial tamponade.

Aortic stenosis: is it simply a degenerative process or an active atherosclerotic process?

Aortic stenosis remains the most common cause of cardiac valve replacement in developed countries. The prevalence of this condition increases with age, and many of the risk factors for coronary artery disease also appear related to the development and progression of aortic stenosis. Recent studies also suggest a relationship between calcium and lipid accumulation in both coronary artery disease and aortic stenosis.

Modulation of cardiovascular remodeling with statins: fact or fiction?

The concept of cardiac remodeling implies a complex mixture of myocardial ischemia, and increased wall stress that results in molecular, cellular and interstitial changes in the heart. Clinically, cardiac remodeling is manifested as a change in size, shape and function of the heart. Morphologically the key feature of remodeling is myocyte hypertrophy, myocyte loss from necrosis or apoptosis, as well as interstitial cell growth especially fibroblast proliferation leading to myocardial fibrosis.

Dietary recommendations in the prevention and treatment of coronary heart disease: do we have the ideal diet yet?

To respond to the question of the best "heart-healthy" diet, we reviewed the effects of common diets on lipids, their efficacy, advantages, and limitations. The high-protein, low-carbohydrate diet is effective for weight loss over the short term, but its long-term benefits remain unproved. The very low-fat diet decreases levels of total and low-density lipoprotein cholesterol and, with lifestyle modifications, may slow progression of coronary atherosclerosis.

Beta-blockade in chronic heart failure: does it work in everyone?

Chronic heart failure continues to exact a heavy burden on society due to high morbidity and mortality, in spite of advances in management. Beta-adrenergic blockade, by the suppression of sympathetic activity, attenuates the adverse ventricular remodeling seen in heart failure, and decreases mortality and hospitalization rates. Recently reported trials, meta-analyses, and sub-analyses extend the benefit of beta-blockade to severe heart failure, women, elderly patients, and African Americans.
