Malattia Cronica : tempo…..

“A disease that persists for a long time.

A chronic disease is one lasting 3 months or more, by the definition of the U.S.

National Center for Health Statistics.

“A disease lasting indefinitely. “

“An illness marked by long duration or frequent recurrence”

Malattia Cronica : prognosi….

“Chronic diseases generally cannot be preventedby vaccines or cured by

medication, nor do they just disappear

“A disease that can be controlled but not cured”

“A disease with one or more of the following characteristics: permanence,

leaves residual disability, caused by non-reversible pathological alternation,

requires special training of the patient for rehabilitation, or may require a

long period of supervision, observation, or care”

Authors’ conclusions

Exercise training improves exercise capacity and quality of life in patients mild to moderate heart failure in the short term. One study found beneficial effects of exercise on cardiac mortality and hospital readmissions over 3 years of follow-up, the remaining included studies did not aim to measure clinical outcomes and were of short duration.

The findings of the review are based on small-scale trials in patients who are unrepresentative of the total population of patients with heart failure.

Other groups (more severe patients, the elderly,women) may also benefit. Large-scale pragmatic trials of exercise training of longer duration, recruiting a wider spectrum of patients are needed to address these issues.

“The results of this meta-analysis strongly support respiratory rehabilitation including at least four weeks of exercise training as part of the spectrum of management for patients with COPD.

We found clinically and statistically significant improvements in important domains of quality of life, including dyspnea, fatigue emotional function.

When compared with the treatment effect of other important modalities of care…rehabilitation resulted in greater improvements in important domains of health-related quality of life and functional exercise capacity.”


Slide32 l.jpg

Conclusion

Early pulmonary rehabilitation after admission to hospital for acute exacerbations of COPD is safe and leads to statistically and clinically significant improvements in exercise capacity and health status at three months.

Adesione e malattie croniche

  • Nonostante la ricerca clinica abbia raggiunto risultati rilevanti

  • per il trattamento e per il controllo delle patologie croniche,

  • più del 50% dei pazienti cronici

  • non riesce ad eseguire correttamente la terapia consigliata

  • Good doctors use

  • both

  • individual clinical expertise

  • the best available evidence,

  • and

  • neither is enough

  • The scientific knowledge to achieve this goal already exists.

Potential for Europe

  • If there are 40 million individuals with a 10 year CV risk of 25%

  • In the absence of treatment every year there will be 1 million strokes and HA

  • About half these could be averted (10 year CV risk 11.25%)

Combination Pharmacotherapy and Public Health Research Working Group Report (CDC & US Experts)

  • Developing countries may manufacture and distribute variations of Combination Pharmacotherapy without waiting for the developed world.

  • We think Combination Pharmacotherapy offers the potential to decrease the incidence of CVD worldwide.

  • This expert panel believes that the concept of CP shows sufficient promise to justify the additional scientific testing of its potential public health applications.

  • Specifically, we recommend further evaluation

“ Regimens of aspirin, two blood-pressure drugs, and a statin could halve the risk of death from cardiovascular disease in high-risk patients.

This approach is cost-effective according to WHO recommendations, and is robust across several estimates of drug efficacy and of treatment cost.

Developing countries should encourage the use of these inexpensive drugs that are currently available for both primary and secondary prevention.”

“Now who's playing God?”

A Polypill for Everything ?

Is polypill approach feasible and effective in preventing cardiovascular damage?
