Study Notes
Heart Failure Causes
- Common causes include coronary artery disease, high blood pressure, and diabetes.
- Other factors include congenital heart defects, valve diseases, and certain medications.
Heart Failure Symptoms
- Advanced heart failure symptoms include shortness of breath at rest, swelling of the legs and ankles, and significant fatigue.
- These symptoms indicate the heart is severely weakened and unable to effectively pump blood.
Heart Failure Medications
- Diuretics are the primary medication class used to reduce fluid overload in heart failure.
- Diuretics help the body eliminate excess fluid, reducing pressure on the heart and improving its function.
Heart Failure Diagnosis
- Echocardiogram is the most helpful test for assessing cardiac function in heart failure.
- It provides detailed images of the heart's structure and function, allowing doctors to diagnose heart failure and monitor its progression.
Heart Failure Therapy
- The main goal of heart failure therapy is to improve the heart's function and quality of life for patients.
- Treatment aims to manage symptoms, prevent complications, and slow the progression of the disease.
Common Causes of Heart Failure
- High Blood Pressure: Constantly high blood pressure puts stress on the heart.
- Coronary Artery Disease: Blockages in the arteries that supply blood to the heart muscle can weaken it.
- Heart Valve Disorders: Leaky or stiff heart valves make the heart work harder.
- Congenital Heart Defects: Heart abnormalities present at birth.
Symptoms Indicative of Advanced Heart Failure
- Shortness of breath at rest: This is a significant sign that the heart is struggling to pump blood effectively even when not active.
Medications for Fluid Overload
- Diuretics: This medication class helps to remove excess fluid from the body, reducing the strain on the heart.
Diagnostic Test for Cardiac Function
- Echocardiogram: This imaging test allows healthcare professionals to assess the heart's structure and function, crucial in diagnosing and managing heart failure.
Goal of Heart Failure Therapy
- Improve quality of life: Through medication and lifestyle changes, the goal is to manage symptoms, improve the heart's function as much as possible, and extend life expectancy.
Pathophysiological Changes in Heart Failure
- Ventricular Remodeling: The ventricles of the heart, responsible for pumping blood, can change shape and size. This negatively impacts their ability to function effectively.
Factors Contributing to Heart Failure Progression
- Age: While age can play a role, the most significant factors are lifestyle choices, presence of existing conditions, and adherence to treatment plans.
Exercise Response in Heart Failure
- Decreased Exercise Tolerance: The heart muscles are weakened, leading to a decrease in the body's ability to sustain physical activity.
Biochemical Marker in Heart Failure
- Brain Natriuretic Peptide (BNP): This hormone is released by the heart when it is under stress and is a marker of heart failure severity that can be measured in blood tests.
Compensatory Mechanism in Heart Failure
- Activation of the Renin-Angiotensin-Aldosterone System (RAAS): This system, normally involved in blood pressure regulation, can be overstimulated in heart failure, leading to salt and water retention, further straining the heart.
