Pulmonary hypertension in the era of mechanical circulatory support.
The researchers summarized the literature available to highlight the definition, pathogenesis, and prognosis of pulmonary hypertension (PH) due to left heart disease (LHD). Additionally, they discussed the use of mechanical circulatory support (MCS) in this population. Then, they provided recommendations regarding the management and reassessment of PH due to LHD in the specific context of MCS.

Use of heart failure medical therapies among patients with left ventricular assist devices: insights from INTERMACS.
The authors examined the use of heart failure medications before and after left ventricular assist devices (LVAD) implant in adult patients enrolled in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). They found that overall use of neurohormonal antagonists was low after LVAD implant, whereas use of loop diuretics and amiodarone remained high, and concluded that heart failure medication use is highly variable, but appears to generally increase after LVAD implantation.

Comparative effectiveness of cardiac resynchronization therapy among patients with heart failure and atrial fibrillation: Findings from the National Cardiovascular Data Registry's Implantable Cardioverter-Defibrillator Registry.
The researchers investigated the outcomes of patients with both atrial fibrillation and heart failure who receive cardiac resynchronization therapy with defibrillator (CRT-D) compared with an implantable cardioverter-defibrillator (ICD) alone. They found that CRT-D was associated with lower risks of mortality, all-cause readmission, and heart failure readmission, as well as with a similar risk of complications compared with ICD alone.

Effectiveness and safety of aldosterone antagonist therapy use among older patients with reduced ejection fraction after acute myocardial infarction.
The purpose of this paper is to describe how aldosterone antagonist treatment is used among older myocardial infarction (MI) patients in routine practice. They found that aldosterone antagonist use was not associated with lower mortality except in symptomatic HF patients, and risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists, as was risk of acute renal failure compared with patients not prescribed aldosterone antagonists. They concluded that these results underscore the importance of close post-discharge monitoring of this patient population.

Comparative effectiveness of implantable cardioverter defibrillators for primary prevention in women.
The researchers examined clinical practice data to compare survival rates among women with heart failure with or without a primary prevention implantable cardioverter defibrillator (ICD). Theyn found that among patients with heart failure with reduced left ventricular ejection fraction, a primary prevention ICD was associated with a significant survival advantage among women and among men.
