Cost-effectiveness in unstable economies: the case of sacubitril/valsartan in heart failure with reduced ejection fraction in Argentina.

Background: Sacubitril/valsartan (an Angiotensin receptor-neprilysin inhibitor-ARNI) is one of the cornerstones in the management of patients with heart failure with reduced ejection fraction (HFrEF) having demonstrated significant reductions in both mortality and hospitalisations as compared with enalapril. It proved to be a cost-effective treatment in many countries with stable economies. In Argentina, a country with chronic financial instability and a fragmented health care system, the estimation of its cost-effectiveness requires to consider local financial data.

Use of aliskiren in Latin America in a real-world setting: aliskiren in Latin America Study (ALAS).

Background: Hypertension (HTN) is one of the major risk factors for cardiovascular disease in Western countries, and disease control is of major relevance in order to reduce cardiovascular morbidity and mortality. Different approaches have shown efficacy, and one of the proven therapies for HTN control is the blockade of the renin-angiotensin-aldosterone system, which may be accomplished by means of various drugs with different modes of action. Aliskiren is a novel direct renin inhibitor that reduces both angiotensin I and II blood levels.
