Heart failure with preserved ejection fraction (HFPEF) may be as common and as lethal as heart failure with reduced ejection fraction (HFREF). Three randomized trials of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ie, renin-angiotensin system [RAS] antagonists) did not reach primary end points but may have had selection bias or been underpowered. ⋯ Among patients with heart failure and preserved ejection fraction, the use of RAS antagonists was associated with lower all-cause mortality.

Management of gout: a 57-year-old man with a history of podagra, hyperuricemia, and mild renal insufficiency.
Gout is an ancient disease. Despite significant advances in the understanding of its risk factors, etiology, pathogenesis, prevention, and treatment, millions of people with gout experience repeated attacks of acute arthritis and other complications. The incidence of gout is increasing, most likely reflecting increasing rates of obesity and other lifestyle factors, including diet. ⋯ Using the case of Mr R, a 57-year-old man with a history of podagra, hyperuricemia, and mild renal insufficiency, the diagnosis and treatment of gout are discussed. For those with moderate to severe gout, urate-lowering treatment can eliminate acute attacks of arthritis and prevent complications. In the near future, it is likely that new risk factors for gout will be identified and new ways of preventing and managing this common disease will become available.
