ALL ROADS LEAD TO CCF

Heart Failure• Final common pathway for many cardiovascular

diseases whose natural history results in symptomatic or asymptomatic left ventricular dysfunction

• Prevalence: Asymptomatic- 4%. Symptomatic 2-3%, 10-20% in those

aged>75yrs.

• Risk of death is 5-10% annually in patients with mild symptoms and increases to as high as 30-40% annually in patients with advanced disease.

Epidemiologyè Most common cause of hospitalization >65 years of

age

Congestive Heart Failure

“The situation when the heart is incapable of maintaining a cardiac output adequate to accommodate metabolic requirements and the venous return”

- Eugene Braunwald

Definition• AHA/ACC defines…

A complex syndrome resulting from any structural or functional cardiac disorder that impairs the ability of the ventricles to fill with or eject blood.

• ESC defines…A Clinical symptoms/ signs secondary to abnormal ventricular function.A complex clinical syndrome in which the heart is incapable of maintaining a cardiac output adequate to accommodate metabolic requirements and the venous return.

The Donkey Analogy Ventricular dysfunction limits a patient's ability to perform the routine activities of daily living…

Main causes

• Coronary artery disease - 70%• Hypertension

• Valvular heart disease – 10%• Cardiomyopathy – 10%• Others – Drugs, Toxins, Nutritional,

Infective, Infiltrative, Cor pulmonale, etc.

Risk Factorsè Coronary heart disease is the foremostè CHD as a primary cause:-

• SOLVD Trial (75% of the cases) • Hillingdon trial (36% of cases)• Framingham heart study (46% in men and 27% in

women

è Coronary artery disease and hypertension (either alone or in combination) account for cases > 90% in the Framingham study

NYHA Functional Classification of heart failure

• Class I: No limitation of physical activity

• Class II: Slight limitation of physical activity

• Class III: Marked limitation of physical activity

• Class IV: Unable to carry out physical activity without discomfort

Lancet. 1993; 342:821-828

ACE Inhibitors in Heart failure • For many years, diuretics and digitalis were accepted as

standard first-line therapy for HF.

• More recently, however, large and well designed clinical studies have shown consistently that ACE inhibitors improve survival and reduce morbidity in patients with LVSD, a condition that leads to chronic HF.

• A meta-analysis of 32 randomised controlled trials in which ACE inhibitors were compared with standard therapy or placebo in 7105 patients with symptomatic HF has shown statistically significant overall reductions with ACE inhibition in both total mortality and in a combined end-point of mortality or hospitalisation*

Summary • In sum, both ACE inhibitors and ARB are

considered appropriate first-line therapy for the treatment of patients with heart failure and LVSD barring a contraindication to therapy.

• Although there is some overlap in the contraindications to their use, existing data indicates significant differences in side effect profiles and tolerability between the two classes.

INDEX

Results from COMETè Carvedilol improves vascular outcomesè Carvedilol provides better protection against vascular eventsè Carvedilol significantly reduces the occurrence of all MIs by 29%è Carvedilol reduces hospitalization for unstable angina by 17%

As compared to metoprolol…è Carvedilol reduces the risk of any MI, any unstable angina or

any stroke by 19%è The effect of v on the combined end point of MI or stroke was

significant (HR 0.75) and the effect on fatal MI or fatal strokewas highly significant (HR 0.46)

Reduces Mortality, Improves Survival

Concluding Remarksè Administering carvedilol in addition to conventional

therapy reduces mortality and attenuates myocardial re-modelling in patients with left ventricular dysfunction following acute MI

è Moreover, mortality has been significantly lower with carvedilol than with metoprolol in patients with mild to severe CHF, suggesting that carvedilol may be the preferred β-blocker

INDEX

Diuretics in HF • Diuretics produce symptomatic benefits

more rapidly than any other drugs for heart failure.

• They can relieve peripheral oedema within hours or days, whereas the clinical effects of digitalis, ACE inhibitors, or beta-blockers may require weeks or months to become apparent (Hall 1995; Packer 1983)
