Resp: Pulmonary Hypertension: Free MSRA Podcast

🫁FREE MSRA PODCAST –Pulmonary Hypertension (PH)A clear, structureddeep dive into this complex and high-yield topic for your MSRA revision. 🧠Key Learning Points📌Definition• PulmonaryHypertension (PH) = elevated pressure in thepulmonary arteries• Increases strain on the right side of the heart, whichcan lead to right heart failure 📌WHO Classification (5Types)🩺 Group 1 – Pulmonary Arterial Hypertension (PAH): • Idiopathic (IPAH) • Heritable (e.g., BMPR2 mutations) • Drug-induced(e.g., fenfluramine) • Associated: CTDs (scleroderma), HIV, portal HTN, congenital heartdisease❤️ Group 2 – Due to left heart disease🌬️ Group 3 – Due to lung disease/hypoxia (e.g., COPD, ILD)🧱 Group 4 – CTEPH (chronicthromboembolic PH)🧩 Group 5 – Multifactorial/unclear causes (e.g.,sarcoid, myeloproliferative disease) 📌Pathophysiology• Vasoconstriction + vascular remodelling + endothelialdysfunction→ ↑ Pulmonaryvascular resistance→ ↑ Pulmonary arterypressure→ Right ventricular hypertrophy→ Right heartfailure 📌Risk Factors🧬 Genetic (BMPR2 mutations)🦠 HIV infection🌬️ COPD, interstitial lung disease🩸 Recurrent PE → CTEPH💊 Drugs (e.g., appetite suppressants)🤰 Pregnancy (high-risk) 📌Symptoms• Progressive dyspnoea, fatigue,angina-like chest pain• Syncope, especially on exertion• Signs of right heart failure: oedema, raised JVP,hepatomegaly• Rarely:haemoptysis, arrhythmias 📌Diagnosis🔍 Stepwise approach: • Blood tests:autoimmune screen, TFTs, LFTs • ECG: RV strain,RBBB • CXR: enlarged PA,RV • Echo: estimate of PA pressure, RV function • Right heart catheterisation = definitive (gold standard) • V/Q scan: for CTEPH • CT chest, cardiacMRI, sleep study, lung function tests 📌Management🎯 Depends on group classificationand severityTreat underlying cause (e.g., SSc, HIV, sleep apnoea)Targeted PH therapy • Endothelin receptor antagonists (bosentan)  • PDE5 inhibitors (sildenafil)  • Prostacyclin analogues (epoprostenol)  • Guanylate cyclase stimulators, CCBs (if vasoreactive)Supportive: oxygen, diuretics, anticoagulation (CTEPH), exercise rehabAdvanced: Atrial septostomy, lung transplant 📌Prognosis• Varies with typeand treatment• Untreated idiopathic PAH: median survival ~2–3 years• With moderntherapies: improved outcomes• CTEPH may be curable with pulmonaryendarterectomy 📌Complications💔 Progressive right heart failure🫁 Respiratory infections💉 Thromboembolism⚡ Arrhythmias🤰 Extremely high maternal mortality – pregnancy is contraindicated🫀 Sudden cardiac death 📎More PulmonaryHypertension MSRA Resources:📝 Revision Notes: https://www.passthemsra.com/topic/pulmonary-hypertension-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/pulmonary-hypertension-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/pulmonary-hypertension-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/pulmonary-hypertension-rapid-quiz/🎓 Respiratory Course: https://www.passthemsra.com/courses/respiratory-for-the-msra/ Hashtags#MSRA#PulmonaryHypertension #MSRARevision #RespiratoryMSRA #BMPR2 #CTEPH#RightHeartFailure #MSRAFlashcards #MSRAExam #NICEGuidelines #MedicalEducation#MSRAOnlineRevision
