  1. Il paziente cardiologico & DISTURBI RESPIRATORI DURANTE SONNO Vincenzo Patruno SOC Pneumologia Riabilitativa I.M.F.R. - Udine

  2. due punti di vista.................. Paziente con apnee durante sonno  quali malattie cardiache ? Paziente con malattie cardiache  quali apnee durante sonno?

  3. Hypertension Cardiac Arrhythmia CoronaryIschemicdisease HeartFailure Epidemiology: discovered the association OSA

  4. Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of Hight Blood Pressure “OSA as first of identifiable causes of hypertension” Chobanian AV. JAMA 2003, 289:2560

  5. 2007 EUROPEAN SOCIETY OF CARDIOLOGY – EUROPEAN SOCIETY OF HYPERTENSION GUIDELINES ….FIRST ACKNOWLEDGE OSA AS ONE OF THE FACTORS RESPONSIBLE FOR RESISTANT HYPERTENSION The Journal of Clinical Hypertension Volume 9, Issue Supplement s1, pages 2–6, January 2007

  6. AtrialFibrillation In a substudy of the Sleep Heart Health Study, individuals with severe sleep apnea had four times the odds of having AF (OR 4.02, 95% CI 1.03–15.74) compared with individuals without OSA, even after adjusting for possible confounding factors. Mehra R, Association of nocturnal arrhythmias with sleep-disordered breathing. The Sleep Heart Health Study. Am J Respir Crit Care Med 2006;173: 910–6. Another cohort study of 3542 patients showed that OSA is an independent risk factors for AF (HR 3.29, 95% CI 1.35–8.04, P . 0.009) Gami AS Obstructive sleep apnea, obesity, and the risk of incident atrial fibrillation. J Am Coll Cardiol 2007;49:565–71.

  7. AF recurrence….. …patients with OSA have a 25% greater risk of AF recurrence after catheter ablation than those without OSA (risk ratio 1.25, 95% confidence interval 1.08 to 1.45)….

  12. Cuore e Respiro: Due punti di vista Paziente con apnee  quali malattie cardiache ? Paziente con malattia cardiaca quali apnee ?

  13. Central Sleep Apnea & Chronic Heart Failure 40% of CHF patients have CSA-CSR Javaheri S. Circulation 1998, 97:2154–2159 -. 27% of CHF patients have CSA-CSRDON D. SIN.AM J RESPIR CRIT CARE MED 1999;160:1101–1106. 69% of CHF patients have CSA-CSR Lanfranchi P. Circulation 2003 feb 11 107/5) 727-732

  20. Clinically, CSA–CSR was associated to higher mortality in CHF

  21. In a large community based study CSA-CSR was not found to be associated with increased mortality

  22. QUALE E’ IL SIGNIFICATO DEL CSR ? FENOMENO CHE RISPECCHIA UN DANNO D’ORGANO……..

  23. QUALE E’ IL SIGNIFICATO DEL CSR ? 1) Meccanismo in se capace di danneggiare il cuore…..? 2) Meccanismo “di compenso” più benefico che dannoso…..?

  24. 258 CHF + CSA/CRS (mean Age 63, FE% 24, AHI 40) CPAP Group 130 Control Group 128 2 years follow-up

  25. CANPAP Commentary • CANPAP study very selective patient set – strongly CSR / CSA (low OSA prevalence) • Beta Blockers not used in all subjects • Low over-all event rate (deaths) leave study under-powered for meaningful conclusions • Early increased mortality with CPAP, but without regard tousage or efficacy

  26. Conclusioni • Nello scompenso cardiaco cronico associato ad apnee ostruttive il trattamento con CPAP migliora la funzione cardiaca • Nello scompenso cardiaco cronico associato ad apnee centrali non sono ancora disponibili evidenze definitive che la correzione efficace del disturbo respiratorio porti a un miglioramento della sopravvivenza...

  27. one last question....... .......agire con il ventilatore per correggere il CSR o agire per migliorare l’emodinamica (che poi il CSR si corregge da solo)? Questo è il problema... http://dx.doi.org/10.1016/j.ijcard.2013.04.107

  28. The unloading effect of CPAP therapy decreases both preload and stroke volumes (SV) in patients with low pulmonary capillary wedge pressure (PCWP). In contrast, PAP therapy increases SV in a state of high PCWP in patients with either exacerbated or stable CHF. This intriguing phenomenon can be explained by diastolic ventricular interaction. Unloading the RV by lower body negative pressure in patients with severe CHF reduces the external constraint on LV filling, resulting in the paradoxical dilation of the LV with a rightward shift of the interventricular septum. Under these circumstances, the Frank-Starling law predicts an increase in SV.
