Q

Pt s/p cardiac transplant 10 months ago now presents with exertional dyspnea and abdominal pain cannon a waves on EKG. What will help establish diagnosis?

Q

Difference btw restrictive cardiomyopathy and constrictive pericarditis?

Why is this difference important?

A

Restrictive Cardiomyopathy - Has Elevated BNP due to Very large heart (HTN, AS, Sarcoid, Amyloid, Hemachromatosis, Cancer and Fibrosis.)

Constrictive Has Pericardial Knock. (Skull Around heart) - In USA Radiation #1 Cause.

Surigical pericardiectomy can relieve symptoms and prolong life with patients with Constriction.

Q

What should be excepted in black patients older than 50 who have left ventricular wall thickening that is not explained by HTN or AS and present with heart failure and features of diastolic dysfunction?

Q waves in anteroseptal leads without regional wall motion abnormalities “ pseudo-infarct”

A

Cardiac Amyloidosis (Cause of Restrictive Cardiomyopathy - Pts will have elevated BNP due to diastolic heart failure, No pericardial Knock).

Endomyocardial biopsy is more sensitive than Abdominal fat pad biopsy
