E’ possibile fare una stratificazione dei rischi affidabile ?

EHS HF II: data collection

Patients screened at the emergency area, including cardiac care unit (CCU) or intensive care unit (ICU), as well as on ward facilities (internal medicine or cardiology)

133 participating hospitals: university hospitals (47%) community or district hospitals (49%) private clinics (4%)

30 European countries Recruitment from 21 October 2004 until 31 August

Research in acute HF: Conclusions

Morbidity and mortality of patients with acute HF remain unacceptably high

Treatment of acute HF continues to remain largely anecdotal without much progress in the last decades

Risk stratification with the identification of simple clinical variables seems to be feasible in any clinical setting

In any case, the application of risk scores in the real world of acute HF could be limited by: The heterogeneity of this clinical condition The different patho-physiological background The various clinical settings (and doctor profiles) in which patients with AHF

are managed Further efforts should be focused on planning research in the

field of AHF

What do we need ?

Data on the clinical characteristics. Definition, sub-clasification (ST/non-ST ) Data on the exact pathophysiology of each

subtype. Better ways to risk-stratify the patients. Treatments to:

Reduce MortalityReduce Morbidity (worsening heart failure?)Rapid and safe symptoms relief

Or in other words … everything…

Comparison of decompensated heart failure with acute myocardial infarction

Decompensated Acute myocardial Heart failure infarction

Hospitalization per year(in US) 1,000,000 1,000,000

In-Hospital Mortality 3-12% 3-7%

Readmission rate (60 days) 35% 10%

Guidelines for risk stratification No Yes

Guidelines for therapy Yes (ESC) Yes

No (AHA/ACC)
