Objective:To assess the safety of sildenafil and dofetilide in patients with pulmonary arterial hypertension (PAH) in a population-based cohort of adult patients with PAH who met the WHO II criteria for PAH.
Patients:The study was a prospective, randomized, double-blind, parallel-group, multicentre, open-label trial with two sites in the USA and 2 sites in the UK. The trial was conducted at the University of Liverpool, United Kingdom. The protocol was approved by the Research Ethics Committee for Human Research of the University of Liverpool, UK (reference no. 09/0.039).
Interventions:Patients were initially assessed for PAH using the International Index of Echocardiography (IIEF) scale and the International Pulmonary Arterial Hypertension (IIHP) questionnaire. The IIEF questionnaire is a comprehensive questionnaire consisting of 5 items: 1) heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulmonary vascular resistance (PVR) at time of assessment. In addition, the IIHP questionnaire is a combination of 5 questions: 1) HR, pulmonary artery pressure (PAP), and pulmonary vascular resistance (PVR); 2) SBP, diastolic blood pressure (DBP), and pulmonary vascular resistance (PVR); 3) DBP, pulmonary artery systolic pressure (PASP), and pulmonary artery distensibility (PAD); 4) PVR, pulmonary artery distensibility index (PADI); 5) HR, systolic and diastolic BP, and HR, pulmonary artery distensibility index (PADI-R).
Results:The study group included 70 patients with PAH, which included 29 males and 15 females with age ranging from 18 to 90 years (mean age of 64 years). The median age was 55 years with a range of 18 to 84 years. The mean PAP was 34 mm Hg, the mean DBP was 28 mm Hg, and mean HR was 39 beats per minute (range: 15 to 45 beats per minute). The median PVR was 0.4 mL/m2, the mean PADI was 4.8 mL/m2, and the mean PADI-R was 3.2 mL/m2. There were no significant differences between the groups on any of the demographic and clinical variables.
Conclusions:Although the IIEF questionnaire is highly sensitive and accurate for assessing HR and PAP in patients with PAH, the IIHP questionnaire is a valuable tool for the assessment of HR in patients with PAH.
Pulmonary arterial hypertension (PAH) is a leading cause of morbidity and mortality in adults. It is estimated to affect approximately 1% of all adult deaths in the United States.1 The prevalence of PAH in the general population is approximately one-third to one-half that of adults.2PAH is characterized by the narrowing of the pulmonary arteries.3 PAH is the result of an imbalance between a decrease in blood supply and an increase in blood flow in the pulmonary veno-artery, which results in the development of pulmonary hypertension (PH).
PAH can be divided into two forms. The first is a form of pulmonary hypertension (PH) which is classified into one of the following groups: idiopathic PAH, congenital PAH, and secondary to the congenital PAH, or idiopathic PAH.
Secondary PH, which is defined as the development of any part of the pulmonary vascular tree in an infant and may be a symptom of idiopathic PAH.
Secondary PH is a group of clinical signs and symptoms associated with PAH.3,5 The term “secondary PH” describes a more specific form of PH that has not been described in the literature.3,5 Secondary PH encompasses the following:
Primary PH:There are two main types of secondary PH: idiopathic PAH and idiopathic pulmonary arterial hypertension (IPAH).6 These are distinguished by their presence of either a decrease in pulmonary arterial blood flow or an increase in systemic vascular resistance, which are referred to as “ secondary PH”.7
Secondary PH can be defined as a reduction in systemic vascular resistance and/or a change in the pulmonary vasculature and the end-arterial resistance index (a measure of pulmonary vascular resistance), a measure of systemic vascular resistance.
