INTRODUCTION: Pulmonary hypertension (PH) is characterized by pulmonary vascular remodeling, right heart failure, and reduced survival. PH can be PH without left ventricular (LV) dysfunction - pulmonary arterial hypertension (PAH) - (Dana point Class I) and PH with LV dysfunction - pulmonary venous hypertension (PVH) - (Dana point Class II). Whatever the underlying cardiac disease, the presence of PH in patients with heart failure is associated with poor prognosis. Right ventricular dysfunction by ventricular interdependence can cause LV dysfunction.
OBJECTIVE: We aim to provide a distinction between PAH and PVH by echocardiography.
METHODS: Retrospective cross-sectional single-center data of 1075 subjects having PH as defined by echocardiography was collected. These were segregated into mild, moderate, and severe categories. The same cohort of PH subjects was also segregated by E/e' derived pulmonary capillary wedge pressure (PCWP) values. Echocardiographic measurements and effort tolerance in Mets were analyzed. Data for 707 normal subjects were taken from an earlier published study on normative echocardiographic measurements of healthy Indians.
RESULTS: Our findings show that PAH and PVH can be distinguished using PCWP value >15 mmHg obtained by applying Nagueh's formulaon E/e'.
CONCLUSION: We recommend that PCWP derived from E/e' should be reported with pulmonary artery systolic pressure measurement to distinguish between PAH and PVH.
