La Marat\u00f3 2014: malalties del cor<\/h2>\n

A Catalunya, una de cada quatre persones mor a causa d\u2019una malaltia del cor.<\/strong><\/p>\n

Poden afectar tothom, tant homes com dones, i a qualsevol edat: des de nadons fins a gent gran. Les malalties del cor s\u00f3n la primera causa d\u2019ingr\u00e9s hospitalari i fan perdre molta qualitat de vida a les persones que en s\u00f3n v\u00edctimes.<\/p>\n

El cor<\/h2>\n

El cor \u00e9s un m\u00fascul que t\u00e9 un sistema el\u00e8ctric propi. Cada est\u00edmul el\u00e8ctric el fa contraure per impulsar la sang. En rep\u00f2s, el cor batega a un ritme constant de seixanta batecs per minut.<\/p>\n

El cor bomba cinc litres de sang cada minut, que es distribueix per tot el cos a trav\u00e9s de les art\u00e8ries i les venes, i t\u00e9 unes v\u00e0lvules que nom\u00e9s permeten que la sang vagi endavant.<\/p>\n

El cor no es regenera. Per tant, el cor que tenim quan naixem \u00e9s gaireb\u00e9 el mateix que tenim quan morim. Ha de funcionar tota la vida.<\/p>\n

Com emmalalteix<\/h2>\n

La xarxa el\u00e8ctrica pot envellir, tenir curt circuits o altres problemes. Quan no funciona b\u00e9, el cor pot deixar de contraure\u2019s de manera sincr\u00f2nica i perd el ritme. \u00c9s el que s\u2019anomena ar\u00edtmia. L\u2019ar\u00edtmia m\u00e9s perillosa \u00e9s la fibril\u2022laci\u00f3 ventricular: el cor tremola i no \u00e9s capa\u00e7 de bombar la sang. S\u2019ha d\u2019aturar r\u00e0pidament, sin\u00f3 provoca mort sobtada. A Catalunya, m\u00e9s de 3.000 persones moren per aquesta causa cada any.<\/p>\n

Quan les v\u00e0lvules s\u2019obren o es tanquen malament es donen les valvulopaties, i provoca que la sang no circuli en la direcci\u00f3 correcta.<\/p>\n

El cor pot tenir defectes de naixement. Pot ser que no estigui completament ben format. Aquestes malalties s\u2019anomenen cardiopaties cong\u00e8nites.<\/p>\n

Les art\u00e8ries que nodreixen el m\u00fascul card\u00edac s\u2019anomenen art\u00e8ries coron\u00e0ries. Quan una es tapa parcialment, causa dolor amb l\u2019esfor\u00e7 (angina de pit). Quan es tapa totalment, mor una part del cor i es produeix el que en diem infart.<\/p>\n

El m\u00fascul del cor pot afeblir-se per diferents motius. Quan el cor no t\u00e9 prou for\u00e7a per bombar la sang, la persona nota cansament i ofec. \u00c9s el que es coneix com a insufici\u00e8ncia card\u00edaca.<\/p>\n

Tractaments<\/h2>\n

Cada vegada es van perfeccionant els tractaments i s\u2019intenten adequar a les necessitats de cada pacient. N\u2019hi ha un ventall molt ampli que va des de medicaments fins a operacions a cor obert.<\/p>\n

La tecnologia \u00e9s cada cop m\u00e9s sofisticada i ja hi ha des de marcapassos sense cables a desfibril\u2022ladors implantables sota la pell.<\/p>\n

Moltes operacions s\u2019intenten fer a trav\u00e9s de cat\u00e8ters que entren per art\u00e8ries de la cama o del canell. Aquest \u00e9s el cas de les pr\u00f2tesis de v\u00e0lvules o els \u201cstents\u201d. El gran avantatge: els pacients pateixen menys i en 3 o 4 dies poden tornar a casa.<\/p>\n","protected":false},"excerpt":{"rendered":"
