Select and explain. 
A. PAP>25mmHg; PCWP>lmmHg, B. PAP >25mmHg; PCWP < 15mmHg, C. PCWP >25mmHg; PAP > 15mmHg, D. PCWP >25mmHg; PAP < 15mmHg
B: PAP >25mmHg; PCWP < 15mmHg
Answer: B: PAP >25mmHg; PCWP < 15mmHg 
Explanation: Ans. is 'b' i.e., PAP > 25mmHg; PCWP < 15mmHg o Pre-capillary Pulmonary Hypertension is defined by Mean Pulmonary Artery Pressure (PAP) > 25mmHg and Pulmonary Capillary Wedge Pressure (PCWP) < 15mm Hg (thereby excluding a cardiac cause).o PH has been defined as an increase in mean pulmonary' arterial pressure (PAP) > 25 mmHg at rest as assessed by right heart catheterization (RHC).DefinitionCharacteristicsClinical group(s)Pulmonary- hypertension (PH)o Mean PAP > 25mmHgo AllPre-capillary PHo Mean PAP > 25mmHgo PWP < 15mmHgo CO normal or reducedo Palmonaty arterial hypertension o PH due to lung diseaseso Chronic thromboembolic PHo PH with under and/or multifactorial mechanismsPost-capillary PHo Mean PAP > 15 mmHgo PWP > 15 mmHgo CO normal or reducedo PH due to left heart disease
