Lone pulmonary hypertension.
Lone (or primary), pulmonary hypertension (P.H.T.) may be defined as a condition of high pressure in the pulmonary artery associated with right ventricular hypertrophy for which no cause can be found outside the pulmonary vessels. The diagnosis is one which is made by exclusion of other diseases which are known to be potential or predisposing causes of P.H.T. The most important of these are chr...
متن کاملThalassemia Associated Pulmonary Hypertension
Cardiac disease is the main cause of death in both forms of thalassemia; thalassemia major (TM) and thalassemia intermedia (TI). Pulmonary hypertension (PH) is one of the cardiopulmonary morbidities with high mortality that, if not treated, may trigger right-sided heart failure and premature death. PH is defined as a mean pulmonary artery pressure of ≥25 mmHg at rest or ≥30 mmHg during exercise...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
متن کاملPulmonary Hypertension Registry: a 10-Year Experience
Background: Pulmonary Arterial Hypertension (PAH), a fatal orphan disease, is defined as increased mean Pulmonary Arterial Pressure (mPAP) above 25 mm/Hg, Pulmonary Capillary Wedge Pressure (PCWP) below 15 mm/Hg, and pulmonary vascular Resistance over 3 Wood Unit (WU). Although Pulmonary Hypertension (PH) is a relatively prevalent disease, the idiopathic form (iPAH) is a rare disease with a pre...
متن کاملPulmonary hypertension caused by pulmonary venous hypertension.
The effect of pulmonary venous hypertension (PVH) on the pulmonary circulation is extraordinarily variable, ranging from no impact on pulmonary vascular resistance (PVR) to a marked increase. The reasons for this are unknown. Both acutely reversible pulmonary vasoconstriction and pathological remodeling (especially medial hypertrophy and intimal hyperplasia) account for increased PVR when prese...
