Complications and Prognosis

Complications and prognosis

\ Prognosis is expressed in broad clinical terms; individual outcome depends on age, comorbidities (e.g., HIV, hypertension), and timely intervention. In Kenya, rheumatic aetiology often leads to earlier presentation of mitral lesions, wher
Key points for the examiner’s mind‑set:
Severity ≠ loudness – a quiet murmur may hide critical obstruction (e.g., severe aortic stenosis with low cardiac output).
Chronology matters – acute severe regurgitation (papillary‑muscle rupture, aortic dissection) carries a dramatically worse short‑term prognosis than chronic compensated lesions.
Complication hierarchy – atrial fibrillation in mitral stenosis is a red flag because embolic stroke risk rises sharply; the examiner expects you to link rhythm disturbance to the underlying valve lesion.

Prognostic pearls for the examiner
The dominant determinant of survival is extent of fibrosis on HRCT (PMF = worst).
Continued exposure after diagnosis shortens survival by 2–3 years on average.
Presence of TB or malignancy overrides the natural history of the pneumoconiosis – the examiner expects you to prioritize treatment of these complications.
DLCO falling below 40 % predicted is a red flag for impending respiratory failure and is often asked as a trigger for referral for lung transplantation (rare in Kenya but conceptually important).

Prognostic pointers that an examiner expects you to mention:
Left ventricular ejection fraction (LVEF) – the strongest predictor of mortality; <35 % confers high risk.
NYHA functional class – each class increase roughly doubles the 1‑year mortality risk.
Renal function – a rise in serum creatinine 0.3 mg/dL after initiation of ACE‑I/ARB signals poorer outcome.
Serum natriuretic peptide trend – failure of BNP/NT‑proBNP to fall after 48 h of optimal therapy suggests ongoing congestion and higher rehospitalisation risk.

Prognostic thinking for the examiner
Identify the stage and aetiology – pre‑renal, intrinsic, post‑renal.
Ask: “Is there a reversible cause still present?” (e.g., ongoing obstruction, persistent nephrotoxin).
Scan for red‑flag complications (AEIOU). Presence of any moves the candidate toward early RRT and a poorer prognosis.
Mention renal recovery trajectory : complete, partial, or progression to CKD/ESRD, and link it to the underlying pathology (ATN → good recovery, severe glomerulonephritis → higher CKD risk).
