Chronic Thromboembolic Pulmonary Hypertension (CTEPH) Results From an International Prospective Registry

Background— Chronic thromboembolic pulmonary hypertension (CTEPH) is often a sequel of venous thromboembolism with fatal natural history; however, many cases can be cured by pulmonary endarterectomy. The clinical characteristics and current management of patients enrolled in an international CTEPH registry was investigated. Methods and Results— The international registry included 679 newly diagnosed (≤6 months) consecutive patients with CTEPH, from February 2007 until January 2009. Diagnosis was confirmed by right heart catheterization, ventilation-perfusion lung scintigraphy, computerized tomography, and/or pulmonary angiography. At diagnosis, a median of 14.1 months had passed since first symptoms; 427 patients (62.9%) were considered operable, 247 (36.4%) nonoperable, and 5 (0.7%) had no operability data; 386 patients (56.8%, ranging from 12.0%– 60.9% across countries) underwent surgery. Operable patients did not differ from nonoperable patients relative to symptoms, New York Heart Association class, and hemodynamics. A history of acute pulmonary embolism was reported for 74.8% of patients (77.5% operable, 70.0% nonoperable). Associated conditions included thrombophilic disorder in 31.9% (37.1% operable, 23.5% nonoperable) and splenectomy in 3.4% of patients (1.9% operable, 5.7% nonoperable). At the time of CTEPH diagnosis, 37.7% of patients initiated at least 1 pulmonary arterial hypertension–targeted therapy (28.3% operable, 53.8% nonoperable). Pulmonary endarterectomy was performed with a 4.7% documented mortality rate. Conclusions— Despite similarities in clinical presentation, operable and nonoperable CTEPH patients may have distinct associated medical conditions. Operability rates vary considerably across countries, and a substantial number of patients (operable and nonoperable) receive off-label pulmonary arterial hypertension–targeted treatments. # Clinical Perspective {#article-title-40}Background— Chronic thromboembolic pulmonary hypertension (CTEPH) is often a sequel of venous thromboembolism with fatal natural history; however, many cases can be cured by pulmonary endarterectomy.

Electrophysiologic studies in atrial fibrillation: Slow conduction of premature impulses: A possible manifestation of the background for reentry

Extrastimulus-induced intraatrial conduction delays were measured in 12 patients with documented episodes of atrial fibrillation (AF) by recording atrial electrograms at the high right atrium, His bundle region, and coronary sinus. Seventeen patients with and without heart disease, but without atrial arrhythmias served as the control group. During baseline-paced atrial rhythms, a conduction delay zone could be delineated, near the atrial effective refractory period, during which all extrastimuli produced conduction delays. When compared at the same paced cycle lengths (500 to 650 ms), the patients with AF had shorter atrial effective refractory periods (mean ± standard deviation 206 ± 24.1 versus 233 ± 28.2 in control patients, p Patients with AF had a higher tendency than control subjects to develop slow intraatrial conduction, as well as shorter effective refractory periods. Since both features would favor reentry, they may be the electrophysiologic manifestations of the abnormalities making these patients prone to atrial reentrant arrhythmias. Repetitive atrial responses were of no predictive value. Sinus nodal dysfunction was frequently found, but was not essential for the occurrence of AF.

Imatinib mesylate as add-on therapy for pulmonary arterial hypertension: results of the randomized IMPRES study.

Background— By its inhibitory effect on platelet-derived growth factor signaling, imatinib could be efficacious in treating patients with pulmonary arterial hypertension (PAH). Methods and Results— Imatinib in Pulmonary Arterial Hypertension, a Randomized, Efficacy Study (IMPRES), a randomized, double-blind, placebo-controlled 24-week trial, evaluated imatinib in patients with pulmonary vascular resistance ≥800 dyne·s·cm−5 symptomatic on ≥2 PAH therapies. The primary outcome was change in 6-minute walk distance. Secondary outcomes included changes in hemodynamics, functional class, serum levels of N-terminal brain natriuretic peptide, and time to clinical worsening. After completion of the core study, patients could enter an open-label long-term extension study. Of 202 patients enrolled, 41% patients received 3 PAH therapies, with the remainder on 2 therapies. After 24 weeks, the mean placebo-corrected treatment effect on 6-minute walk distance was 32 m (95% confidence interval, 12–52; P=0.002), an effect maintained in the extension study in patients remaining on imatinib. Pulmonary vascular resistance decreased by 379 dyne·s·cm−5 (95% confidence interval, −502 to − 255; P<0.001, between-group difference). Functional class, time to clinical worsening, and mortality did not differ between treatments. Serious adverse events and discontinuations were more frequent with imatinib than placebo (44% versus 30% and 33% versus 18%, respectively). Subdural hematoma occurred in 8 patients (2 in the core study, 6 in the extension) receiving imatinib and anticoagulation. Conclusions— Imatinib improved exercise capacity and hemodynamics in patients with advanced PAH, but serious adverse events and study drug discontinuations were common. Further studies are needed to investigate the long-term safety and efficacy of imatinib in patients with PAH. Clinical Trial Registration— URL: http://www.clinicaltrials.gov.

Pulmonary vascular remodeling in pulmonary hypertension due to chronic heart failure.

Pulmonary hypertension (PHT) associated with chronic heart failure (CHF) is a risk factor of right ventricular failure after heart transplantation (HT). Our aim was to study pulmonary vascular changes in patients with CHF and to assess any correlation with haemodynamic data.

Survival in pulmonary hypertension in Spain: insights from the Spanish registry

A pulmonary hypertension (PH) registry (Spanish Registry of Pulmonary Arterial Hypertension) was undertaken to analyse prevalence, incidence and survival of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) in Spain, and to assess the applicability of recent survival prediction equations. Voluntary reporting of previously diagnosed and incident PAH or CTEPH cases (July 2007–June 2008) was performed. Demographic, functional and haemodynamic variables were evaluated. 866 patients with PAH and 162 with CTEPH were included. PAH associated with toxic oil syndrome and pulmonary veno-occlusive disease were reported for the first time in a PAH registry. Estimated prevalences were as follows: PAH, 16 and CTEPH, 3.2 cases per million adult inhabitants (MAI). Estimated incidences were as follows: PAH, 3.7 and CTEPH, 0.9 cases per MAI per yr. 1-, 3- and 5-yr survival was 87%, 75% and 65%, respectively, with no differences between PAH and CTEPH. Male sex, right atrial pressure and cardiac index were independent predictors of death. Matching between observed survival and that predicted by different equations was closer when the characteristics of the cohorts were similar. Epidemiology and survival of PAH patients in the Spanish registry are similar to recent registries. Characteristics of the population from which survival prediction equations are derived influence their applicability to a different cohort. CTEPH is much less prevalent than PAH, although has a similar survival rate.

Impact of mild pulmonary hypertension on mortality and pulmonary artery pressure profile after heart transplantation.

BACKGROUND Pulmonary hypertension is a risk factor for early mortality after transplantation, but the risk threshold is debated. Also, little is known about the evolution of pulmonary circulation after transplantation. The aim of this study was to determine the influence of current risk pulmonary pressure parameters on early post-operative mortality and to assess the time-related changes in pulmonary pressure after surgery. METHODS One hundred twelve consecutive transplanted patients were studied retrospectively to determine the influence of trans-pulmonary gradient of >12 mm Hg and pulmonary vascular resistance of >2.5 Wood units, at baseline or after vasodilator test, on early mortality. A multivariate analysis was used to study the hemodynamic parameters associated with early mortality. The pulmonary pressures of all surviving patients were studied for up to 3 years after surgery. RESULTS Early mortality in the groups with and without pulmonary hypertension were 24.4% and 5.6%, respectively (p =.009). The only variable that was independently associated with early mortality was the pulmonary vascular resistance index (odds ratio = 1.459). Mild pulmonary hypertension disappeared 1 year after heart transplantation. CONCLUSIONS Mild pulmonary hypertension is a risk factor for early postoperative mortality. The hemodynamic parameter most closely associated with early mortality is pulmonary vascular resistance index. The hemodynamic profile of pulmonary circulation after heart transplantation is partially dependent on the level of pulmonary hypertension before transplantation, at least during the first year after surgery.

Clinical and pathologic manifestations of pulmonary vascular disease in the toxic oil syndrome

The toxic oil syndrome in Spain affected greater than 20,000 people. In the initial stages, it was characterized by a respiratory distress syndrome with myalgias and eosinophilia. Pulmonary hypertension developed in 20% of the patients and in many, it has spontaneously regressed. Nevertheless, in a small subgroup, it has progressed to a malignant course of cor pulmonale, leading rapidly to death. Clinical and pathologic features of 40 patients with severe pulmonary hypertension due to the toxic oil syndrome are presented (32 female and 8 male patients; mean age 26 +/- 13 years). The study began in June 1981, which was near the onset of the toxic oil epidemic, and ended in December 1987, greater than 6 years later. The pulmonary hypertension is clinically and pathologically indistinguishable from primary pulmonary hypertension. Direct endothelial injury by the toxic agent is proposed as the initial trigger of this type of pulmonary hypertension, but an interaction between the toxic agent and specific individual susceptibility is probably required in its pathogenesis.
