• La diagnosi è certa?• Possiamo migliorare la terapia?

– Verapamile 240, irbesartan, 300, furosemide 25, spironolattone 37.5, idroclorotiazide (aggiunto), sintrom?

• Quanto una terapia aggressiva delle comorbidità – diabete, obesità, ipotiroidismo - può influenzare l’evoluzione dello SC?

Treatment of cardiac Treatment of cardiac pathophysiologicalpathophysiologicalmechanismsmechanisms

• Maintain atrial contraction Cardioversion for A FibSequential A-V Pacemaker

• Prevent or reduce LVH Antihypertensive drugs

Surgery (AVR for AS)• Prevent/treat ischemia -blocker, Ca++ entry blocker

Nitrates• Reduce HR/increase -blocker, Ca++ entry blocker

filling time Digitalis (AF)• Avoid LVOT obstruction Avoid arterial vasodilatators• Reduce interstitial fibrosis Ace-i/ARBs, antialdosterone

Goal of therapy Methods of treatment

• Nessun trattamento ha mostrato convincentemente di ridurre la mortalità e la morbidità

• Diuretici: riducono edema e dispnea

• Terapia aggressiva per il controllo della PA (ACEI/ARB 1a scelta)

• Terapia aggressiva per il controllo dell’ischemia

• Controllo della FC nei pazienti in FA (verapamil)

• Terapia aggressiva del diabete

In absence of a comprehensive diastolic assessment

Simple echocardiographic criteria

- left atrial enlargement- normal LV dimension- left ventricular hypertrophy- wall motion abnormalities- elevated pulmonary pressures

Considerazioni

• Tipico paziente con SC diastolico vedi dia andrea da inserire eventualmente anche dia su FP dispnea cardiaca

• Mai ricoveri ospedalieri per sc almeno negli ultimi 7 anni (in precedenza comunque solo ricoveri per FA da cardiovertire eccetto uno dei primi episodi di FA associati ad

importante sintomatologiaSC) prognosi favorevole• Gestione integrata MMG-Cardiologo• Poteva essere proponibile ablazione FA in

passato almeno?

Si poteva fare di meglio?

• Forse si, forse no……credo di no

EF “CUT-OFF” : 40% or 50%EF “CUT-OFF” : 40% or 50% ?1) Some studies report a EF cut-off 40% and others 50%

2) The frequency of EF among 40-50% is approximately 10%

3) When preserved EF was defined as >50% the results of mortality, readmission and functional decline remained similar to the group of EF 40-50% (Smith GL et al, JACC 2003)

The predominant pathophysiological cause of heart failure in these patients is abnormal diastolic function (Zile MR)
