Study Notes

Heart Failure Overview

Heart failure is the heart's inability to supply adequate oxygenated blood, leading to fluid buildup in the pulmonary or systemic circulation.
It's a complication of many heart conditions, resulting from structural or functional problems in the ventricles.
Key symptoms include dyspnea (shortness of breath), fatigue, and fluid retention.
The older term "congestive heart failure" is less accurate.
Left-sided failure causes pulmonary congestion, while right-sided failure shows systemic congestion. Both may occur independently or together.
Acute pulmonary edema, fluid in the lungs, is a severe symptom of left-sided heart failure and a life-threatening condition.

Acute Pulmonary Edema

Acute pulmonary edema is characterized by fluid buildup in the lungs.
It causes marked difficulty breathing, leading to a sensation of suffocation and chest oppression.
Symptoms include heightened heart rate and blood pressure, further stressing the heart.
Hypoxemia (low oxygen in the blood) can worsen the problem, creating a harmful cycle leading to rapid death if not addressed promptly.

Heart Function and Dysfunction

The heart acts as a pump, maintaining blood flow to supply the body's tissues and organs with necessary oxygen and nutrients.
Heart disorders, genetic, metabolic and environmental, can affect its function.
Cardiac dysfunction presents in two primary ways: directly at the heart (chest pain, palpitations, etc.) or extracardiac symptoms (caused by blood flow issues to organs).
Left ventricle is more susceptible to damage than the right, and therefore left-sided heart failure is more common.

Heart Failure Statistics and Prognosis

5.7 million Americans (2.3% of the U.S population) had heart failure in 2009.
Heart failure prevalence increases with age, impacting a greater percentage of individuals aged 75 and older.
Heart failure was directly, or indirectly, noted in more than 280,000 deaths (1 in 9) in 2008.
Heart failure prognosis is poor. 80% of men, 70% of women under 65 with heart failure die within 8 years of diagnosis, with 50% dying within 5.
1-year mortality rate is high, at 1 in 5.
Sudden cardiac death is 6 to 9 times more likely in patients with heart failure.
Deaths from heart failure increased 35.3% from 1992-2002..

Heart Failure and Dental Treatment

Patients with heart failure are at higher risk during dental procedures.
Dental treatment plans should consider the extent of heart dysfunction.
Acute pulmonary edema (a symptom of worsening heart failure) due to physiological or emotional stress during dental treatment is a significant concern.
Patients should be adequately assessed prior to procedures to avoid triggering acute situations.
