Pulmonary Hypertension Due to Left Heart Disease

The most common cause of pulmonary hypertension is left heart disease, arising in response to increased left ventricular or left a trial filling pressures[1,2,3]. During the 5th World Symposium held in Nice, France, in 2013, the consensus was reached to maintain the general scheme of previous clinical classifications, placing the Pulmonary Hypertension due to left heart disease in Group 2 [4]. PH is defined by a mean pulmonary arterial pressure >25 mmHg. In the case of PH associated with LHD, this is associated with a pulmonary capillary wedge pressure >15 mmHg or left ventricular end-diastolic pressure (LVEDP) > 18 mm Hg [1,5]. Pulmonary hypertension due to left-sided heart disease is associated with higher morbidity and mortality [6,7,8]. This study is done to know the pattern of clinical presentation of pulmonary hypertension and to see the gender difference.
