Angiotensin II receptor blockers (ARBs) are one of the most frequently used antihypertensive drugs with good tolerability and are indicated for treatment of many cardiovascular morbidity. Findings from clinical studies conducted in the past decade, suggest a possible relationship between some ARB-active substances, and certain malignancies cannot be excluded. ⋯ However, according to the current official position of FDA, the cardiovascular benefits of ARB therapy far outweigh the risks. Based on the limited information available, this review aims to provide medical practitioners with a clearer view on the balance of the benefits and risks of ARBs.

Randomized Controlled Trial Comparative Study
Diagnostic performance and cost of CT angiography versus stress ECG--a randomized prospective study of suspected acute coronary syndrome chest pain in the emergency department (CT-COMPARE).
Coronary CT angiography (CCTA) has high sensitivity, with 3 recent randomized trials favorably comparing CCTA to standard-of-care. Comparison to exercise stress ECG (ExECG), the most available and least expensive standard-of-care worldwide, has not been systematically tested. ⋯ CCTA had improved diagnostic performance compared to ExECG, combined with 35% relative reduction in length-of-stay, and 20% reduction in hospital costs. These data lend further evidence that CCTA is useful as a first line assessment in emergency department chest pain.

Randomized Controlled Trial Multicenter Study
Acute decompensated heart failure patients admitted to critical care units: insights from ASCEND-HF.
Little is known about global patterns of critical care unit (CCU) care and the relationship with outcomes in patients with acute decompensated heart failure (ADHF). Whether a ward or a CCU admission is associated with better outcomes is unclear. ⋯ Management of patients with ADHF varies significantly, and after adjustment, CCU care was associated with higher risk of early mortality, not explained by international differences. These findings may help to improve the early decisions regarding risk stratification of patients hospitalized with ADHF.

Numerous registries, including the most recent ESC Euro-observational registry, have reported a large and persistent gap between real-life practice in the use of life-saving evidence-based therapies (such as renin angiotensin antagonists, beta-blockers, mineralocorticoid receptor antagonists) and recommended practices in international guidelines. Although the use of multiple renin angiotensin aldosterone system-inhibitors is associated with the development of worsening renal function and hyperkalemia in patients with heart failure and reduced ejection fraction, increased efforts should be expended to initiate and maintain target doses of these agents so as to provide their benefits on mortality and hospitalizations for heart failure.
