Randomized Controlled TrialDiagnostic value of poor R-wave progression in electrocardiograms for diabetic cardiomyopathy in type 2 diabetic patients.
Diabetic cardiomyopathy (DCMP) is a common complication of diabetes and is associated with increased mortality. It has been suggested that a poor R-wave progression in a resting electrocardiogram (ECG) could be a sign of cardiomyopathy. ⋯ LV diastolic dysfunction is more frequently observed in diabetic patients with poor R-wave progression in ECG, which may be an early sign of LV dysfunction and DCMP in diabetics.

ReviewRenin inhibitors in chronic heart failure: the Aliskiren Observation of Heart Failure Treatment study in context.
Renin-angiotensin aldosterone system (RAAS) activation is a key neurohormonal contributor to the progression of chronic heart failure. Strategies that block this activation have consistently demonstrated major beneficial impacts on morbidity and mortality in this setting. Direct renin inhibitors (DRIs) present a novel opportunity to block at an additional or alternative step in this pathway, that being conversion of angiotensinogen to angiotensin I. ⋯ Large-scale outcome trials are, however, required to definitively determine the benefits of a DRI strategy additional to, or as an alternative to, conventional approaches such as ACE inhibitors in the systolic chronic heart failure setting.
