The elderly are a rapidly growing segment of the population with a high likelihood of acute coronary disease and worse outcomes after acute coronary syndromes than younger groups. Although underrepresented in clinical trial populations, they benefit to an equal or greater extent from treatment with proven medications and interventions, and survivors to hospital discharge have excellent longer term functional outcomes. With consideration of individual preferences for treatment and inherent risks for side-effects in this population, age alone should not determine management of elderly acute coronary syndrome patients.

Prosthetic valve endocarditis (PVE) is associated with a high mortality during the early and midterm follow-up despite diagnostic and therapeutic improvements; its incidence is increasing and reaches 20-30% of all infective endocarditis episodes. In this review, changes in epidemiology, microbiology, diagnosis and therapy that have evolved in the past few years are analyzed. Staphylococci (both Staphylococcus aureus and coagulase-negative Staphylococcus) have emerged as the most common cause of PVE and are associated with a severe prognosis. ⋯ Therapy is not indicated by evidence-based recommendations but mostly on identification of the high-risk conditions. A PVE is a common indication for surgery, whereas medical treatment alone may be achieved in a few instances. Systematic prophylaxis should be used to prevent this severe complication of cardiac valve replacement.

ReviewCardiological features in idiopathic inflammatory myopathies.
Idiopathic inflammatory myopathies (IIMs) represent a heterogeneous group of autoimmune systemic diseases characterized by chronic muscle weakness and inflammatory cell infiltrates in skeletal muscle. The most frequent IIMs, such as adult-onset polymyositis and dermatomyositis, display a wide range of clinical manifestations other than myositis, including skin changes, Raynaud's phenomenon and interstitial lung disease. Cardiac involvement is now well recognized as a clinically important manifestation in patients with polymyositis or dermatomyositis, although its actual frequency is still uncertain. ⋯ Chronic inflammation producing myocyte degeneration, tissues fibrosis and vascular alterations can explain the majority of reported cardiac features in myositic patients. Although previous works reported an association between heart involvement and some myositis-specific autoantibodies (namely anti-signal recognition particle), electrocardiography, echocardiography and, where necessary, heart magnetic resonance remain the mainstay for diagnosing and monitoring myocardial inflammation in these diseases. Anyway, a complete multiorgan assessment and a careful analysis of autoantibodies should be performed in every patient in order to define any possible distinct disease entities with different prognosis within the spectrum of IIMs.

ReviewMedical therapy of pericardial diseases: part II: Noninfectious pericarditis, pericardial effusion and constrictive pericarditis.
The treatment of pericardial diseases is largely empirical because of the relative lack of randomized trials compared with other cardiovascular diseases. The main forms of pericardial diseases that can be encountered in the clinical setting include acute and recurrent pericarditis, pericardial effusion with or without cardiac tamponade, and constrictive pericarditis. Medical treatment should be targeted at the cause as much as possible. In this article, the therapy of more common forms of noninfectious pericarditis (pericarditis in systemic autoimmune diseases and neoplastic pericardial disease), pericardial effusion, and constrictive pericarditis is reviewed.
