how can we diffrentiate between - zkadhem - ArchivalUser - 02-20-2008 restrictive cardiomyopathy and constrictive pericarditis? 0 - ArchivalUser - 02-20-2008 restrictive cardiomyopathy..........function of diastole. E.Fraction slightly reduces. CO remains normal. xray shows crdiomegaly. contrict pericard.............xray shows normal heart. ekg shows PR segment depression. auscultation revels low intensity of apex beat. 0 - ArchivalUser - 02-20-2008 clinical findings more or less the same? Echo helps in diagnosis. thickening of myometrium in restrictive cardiomyopathy. any other inputs. i always struggle with this one. thanks zkadhem for posting this thread. 0 - ArchivalUser - 02-20-2008 hi biochem2... restrictive cardiomyopathy is char. by diastolic dysfunction due to a stiff ventricular wall.cxr shows only mild enlargment of the cardiac silhoutte.ECHO-->shows symmetrically thickened ventricle walls,normal or slightly reduced lt ventricular size and normal ornear normal systolic function.kussmoul's sign is positive.the apical impulse is easily palpable in restrictive cardiomyopathy as opposed to constrictive pericarditis. with constrictive pericarditis --->cxr may show pericardial calcification and the ctscan usually shows increased thickness of the pericardium.Kussmoul's sign may also be positive .The myocardium thickness is normal in pericaditis. 0 - ArchivalUser - 02-20-2008 RCM------decreased LVEF Pericarditis------increased LVEF |
