2013 ACCF/AHA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines

This document is an international evidence-based guideline on the diagnosis and management of idiopathic pulmonary fibrosis, and is a collaborative effort of the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society, and the Latin American Thoracic Association. It represents the current state of knowledge regarding idiopathic pulmonary fibrosis (IPF), and contains sections on definition and epidemiology, risk factors, diagnosis, natural history, staging and prognosis, treatment, and monitoring disease course. For the diagnosis and treatment sections, pragmatic GRADE evidence-based methodology was applied in a question-based format. For each diagnosis and treatment question, the committee graded the quality of the evidence available (high, moderate, low, or very low), and made a recommendation (yes or no, strong or weak). Recommendations were based on majority vote. It is emphasized that clinicians must spend adequate time with patients to discuss patients' values and preferences and decide on the appropriate course of action.

Definition, prevalence and pathophysiologic role of iron deficiency in pulmonary vascular disease


 Introduction:
 Right ventricular (RV) diastolic dysfunction in pulmonary arterial hypertension (PAH) remains poorly understood. In this study, we used RV pressure-volume (PV) loops to assess RV diastology as a function of afterload in PAH.
 
 
 Methods:
 RV PV loops were prospectively measured in control (n=9) and PAH (n=39) patients at rest and during supine bike exercise. PAH patients were stratified by effective arterial elastance (Ea), a lumped measure of total afterload, into two groups: high afterload (HA, n=20) and severe afterload (SA, n=19).
 
 
 Results:
 PAH groups were matched with respect to age, sex, and PAH medication usage. Ea at rest and exercise was higher in SA PAH (1.8 vs. 0.6 mmHg/ml, P <0.0001 at rest; 2.3 vs 0.8 mmHg/ml, P < 0.0001 with exercise). In the SA group, RV end-diastolic pressure (RVEDP) was higher at rest (13.3 vs 7.6 mmHg, P = 0.0017) and rose markedly with exertion (23.4 vs 13.1 mmHg, P=0.0001). Because RV volumes changed similarly in both groups, SA patients exhibited stiffer RVs (dP/dV 0.30 vs 0.11 mmHg/mL, P=.024). To understand pericardial-interventricular interactions, we calculated the RVEDP-to-pulmonary capillary wedge pressure (PCWP) ratio and the left ventricular (LV) transmural filling pressure (LVTMFP). RVEDP/PCWP was substantially higher in SA (2.1 vs 1.0, P=.005). Therefore, even though PCWP rose considerably in SA (mean 16 mmHg), exercise LVTMFP was significantly reduced in SA vs HA PAH (-7.5 vs 2.55 mmHg, P=0.002). Along with reduced LV size seen by concomitant echo, we thus revealed blunted LV filling specifically in SA PAH. Accordingly, exercise cardiac index, stroke volume index, and LV stroke work index were all markedly reduced in SA PAH.
 
 
 Conclusions:
 Severe afterload in PAH results in high RV diastolic pressures and RV stiffening, which in turn blunt LV filling and LV output with exertion. Due to ventricular interactions, exercise PCWP may rise considerably in PAH, thus reducing its ability to differentiate from left heart disease.
