II. Epidemiology

  1. Prevalence: 5.2 Million with CHF in the United States
  2. Incidence: 400,000 cases CHF diagnosed per year
  3. Morbidity: 870,000 hospitalizations (estimates in 2013 approach 1 Million)
    1. Re-hospitalization rate within 30 days approaches 20%
  4. Mortality: 200,000 patients die from CHF per year
  5. CHF costs
    1. Accounts for 5-10% of all hospital admissions
    2. Annual U.S. Cost: $38.1 billion ($44.6 billion by 2015)

III. Pathophysiology

  1. Heart Failure is a syndrome, not a disease
    1. Heart Failure is a final common pathway
    2. Maximize treatment of the underlying causes
    3. Control the causes and prevent end organ damage

IV. Precautions

  1. Heart Failure is a clinical diagnosis best made by an astute clinician with history and exam
  2. Labs (e.g. BNP) and diagnostics (e.g. Echocardiogram) should be adjunctive only to confirm and follow the diagnosis

VI. Causes

VII. Types

  1. Systolic Dysfunction (60-70% of Heart Failure cases)
    1. Decreased contractility
    2. Decreased Left Ventricular Ejection Fraction
  2. Diastolic Dysfunction (30-40% of Heart Failure cases)
    1. Decreased compliance
    2. Decreased filling
    3. Variable Left Ventricular Ejection Fraction

VIII. Labs

Ontology: Edema (C0013604)

Definition (MEDLINEPLUS)

Edema means swelling caused by fluid in your body's tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body.

Causes of edema include

To keep swelling down, your health care provider may recommend keeping your legs raised when sitting, wearing support stockings, limiting how much salt you eat or taking a medicine called a diuretic - also called a water pill.

Definition (NCI) Swelling caused by excess fluid in body tissues.
Definition (UWDA) Pathological transudate within one or more tissues.
Definition (NCI) Accumulation of an excessive amount of watery fluid in cells or intercellular tissues.
Definition (CSP) swelling from excessive accumulation of serous fluid in tissue.
Definition (MSH) Abnormal fluid accumulation in TISSUES or body cavities. Most cases of edema are present under the SKIN in SUBCUTANEOUS TISSUE.

Ontology: Heart failure (C0018801)

Definition (NCI) A disorder characterized by the inability of the heart to pump blood at an adequate volume to meet tissue metabolic requirements, or, the ability to do so only at an elevation in the filling pressure.
Definition (NCI) Inability of the heart to pump blood at an adequate rate to fill tissue metabolic requirements or the ability to do so only at an elevated filling pressure.
Definition (MEDLINEPLUS)

Heart failure is a condition in which the heart can't pump enough blood throughout the body. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should.

The weakening of the heart's pumping ability causes

  • Blood and fluid to back up into the lungs
  • The buildup of fluid in the feet, ankles and legs - called edema
  • Tiredness and shortness of breath

The leading causes of heart failure are coronary artery disease, high blood pressure and diabetes.

Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.

Heart failure is a serious condition. About 5 million people in the U.S. have heart failure. It contributes to 300,000 deaths each year.

NIH: National Heart, Lung, and Blood Institute

Definition (CSP) inability of the heart to pump blood at an adequate rate to fill tissue metabolic requirements or the ability to do so only at an elevated filling pressure.
Definition (NCI) Inability of the heart to pump blood at an adequate rate to meet tissue metabolic requirements or the ability to do so only at an elevated filling pressure.
Definition (MSH) A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
