Oral Levosimendan in Patients with Severe Chronic Heart Failure --the Persist Study

This is a report of a randomized clinical trial of oral levosimendan as a chronic treatment for HFrEF. 300 patients were included in the trial which lasted 6 months. The primary endpoint, which was not achieved, was a novel composite that included symptoms and mortality. The secondary endpoints of NT-proBNP and patient questionnaire were achieved. Serious adverse events were not encountered.

Pharmacotherapy in Pulmonary Arterial Hypertension: A Systemic Review and Meta-Analysis

Unbiased meta-analysis of the approved pulmonary vasodilator therapies for PAH. The authors improved upon two previous meta-analyses by addressing some of the limitations in those analyses. By pooling the available literature, they sought to determine the effect of the classes of medication on total mortality and secondarily to assess their impact on other clinical endpoints, including dyspnea, exercise tolerance, hemodynamics, and adverse effects

Modern Age Pathology of Pulmonary Arterial Hypertension

Authoritative review of the pathology of PAH, with a focus on the impact of modern treatments by leading experts. They show that in patients with advanced disease there is a distinct spectrum of pulmonary vascular and nonvascular pathologies, including localized interstitial and perivascular inflammation. In this set of patients who were being treated with the modern drug therapies, the appearance of classical pulmonary vascular lesions related to the disease was unaffected.

Targeting of Platlet-Derived Growth Factor Signaling in Pulmonary Arterial Hypertension

Detailed review of the role of PDGF in PAH. The authors provide solid evidence that inhibition of PDGFR signaling by imatinib mesylate represents an encouraging therapeutic concept and is likely to become an additional targeted therapy for PAH. In addition to existing therapies, this anti-proliferative approach has the potential to establish a sustained reduction of the underlying pulmonary vascular remodeling.
