* To provide physical activity recommendations for people with cardiovascular disease, an Expert Working Group of the National Heart Foundation of Australia in late 2004 reviewed the evidence since the US Surgeon General’s Report: physical activity and health in 1996. * The Expert Working Group recommends that: o people with established clinically stable cardiovascular disease should aim, over time, to achieve 30 minutes or more of moderate intensity physical activity on most, if not all, days of the week; o less intense and even shorter bouts of activity with more rest periods may suffice for those with advanced cardiovascular disease; and o regular low-to-moderate level resistance activity, initially under the supervision of an exercise professional, is encouraged. * Benefits from regular moderate physical activity for people with cardiovascular disease include augmented physiological functioning, lessening of cardiovascular symptoms, enhanced quality of life, improved coronary risk profile, superior muscle fitness and, for survivors of acute myocardial infarction, lower mortality. * The greatest potential for benefit is in those people who were least active before beginning regular physical activity, and this benefit may be achieved even at relatively low levels of physical activity. * Medical practitioners should routinely provide brief, appropriate advice on physical activity to people with well-compensated, clinically stable cardiovascular disease.

Objective: To estimate the prevalence of heart failure (HF) and left ventricular (LV) systolic dysfunction in a population-based sample of older Australians. Design, setting and participants: A cross-sectional survey of 2000 randomly selected residents of Canberra, aged 60-86 years, conducted between February 2002 and June 2003. Participants were assessed by history, physical examination by a cardiologist, and echocardiography. Main outcome measures: Age- and sex-specific prevalence rates of clinical HF and LV systolic dysfunction (defined as LV ejection fraction

The Neural Crest (NC) is a multipotential group of cells that arises from the dorsal aspect of the neural tube early in development. It is well established that a group of NC cells named Cardiac Neural Crest (CNC) migrates to the heart and plays a critical role in the remodeling of the aortic arch arteries and septation of the outflow tract. In this study, using the mouse mutant Pax3sp/sp that has CNC deficits I have identified a putative novel role for the CNC in regulating apoptosis in the atrioventricular (AV) endocardial cushion. The AV endocardial cushion undergoes remodeling to give rise to the cardiac AV valves. Using a transgenic mouse that carries the LacZ reporter gene under the control of the Dopachrome tautomerase promoter (Dct-LacZ), I found that another NC derived population, melanocyte precursors, also contribute to the AV endocardial cushion and developing AV valves. The analysis of Dct-LacZ embryos at different stages showed that NC cells already committed to the melanocytic fate migrate to the heart along the same initial pathway taken by those that will populate the skin. Hypopigmented mice carrying mutations in the Kit and Endothelin receptor b genes, that are critical for the proper development of skin melanocytes, do not have cardiac melanocytes indicating that cardiac and skin melanocyte precursors share the same initial signaling requirements. The analysis of murine adult hearts showed that melanocytes are mostly found in the atrial sides of the tricuspid and mitral valve leaflets. The distribution of melanocytes in the AV valves corresponds exactly to areas of high Versican B expression, a proteoglycan essential for the process of AV valve remodeling. To evaluate a potential role for melanocytes in the AV valves, a nanoindentation analysis of the tricuspid valves of wild type, hypopigmented and hyperpigmented mice was performed. The storage modulus, a measure of stiffness, for the leaflets obtained from hyperpigmented mice was considerably higher (10.5GPa) than that for the leaflets from wild type (7.5GPa) and hypopigmented animals (between 3.5 and 5.5 GPa) suggesting that melanocytes may contribute to the mechanical properties of the AV valves.
