    BOLILE PERICARDULUI Diaconu Oana Mihaela    DEFINITIE * Pericardita acuta-   sindrom produs de inflamatia pericarduluiprin variate cauze, caracterizat prin dureri toracice, frecaturapericardica, revarsat pericardic si modificari electrocardiograficecaracteristice . * Tamponada pericardica sau cardiaca   consta incompresiunea cordului de catre revarsatul pericardic careafecteaza umplerea diastolica a ventriculilor, generand tulburariclinice si hemodinamice severe prin reducerea debitului cardiac sicresterea presiunii venoase sistemice si pulmonare. Pericardita constrictiva - apare ca urmare a unui proces defibrozare (±calcificare) la nivelul ambelor straturi pericardice carese transforma intr-o “cusca”rigida pe parcursul unei evolutii delunga durata (ani,sau mai rar luni) dupa variate momente cauzale-episod definit de pericardita acuta infectioasa in general dar maiales TBC, iradiere, interventii chirurgicale cardiace.      Clasificarea pericarditelor  * clinica →pericardita acuta (sub 6 sapt.) →fibrinoasa→lichidiana (efuziva)→pericardita subacuta (6 sapt- 6 luni) →efuziv-constictiva→constrictiva→pericardita cronica (peste 6 luni) →constrictiva→efuziva→adeziva (nonconstrictiva)* etiologica →  infectioasa→ neinfectioasa→ prin mecanisme de hipersensibilizare sau autoimunitate    ETIOLOGIE * idiopatica * infectioasa →virala: vir.Coxsackie, Echovirus, Adenovirus, mononucleozainfectioasa, varicela, hepatita B, SIDA→bacteriana: stafilococ, pneumococ, streptococ, Neisseriameningitidis, Neisseria gonorrhoeae, legionella→ Tuberculoza→fungica: histoplasmosis, candida, blastomicosis→alte infectii: toxoplasmoza, amebiaza, echinococoza, boala Lyme* neinfectioasa → neoplazii: pulmon, san, leucemii, limfom, b.Hodgkin→ IMA, sdr. Dressler → uremie (cu sau fara hemodializa)→radiatii
