Study Notes
Congestive Heart Failure (CHF)
- CHF occurs when the heart cannot pump blood efficiently, resulting in insufficient oxygen-rich blood reaching vital organs.
- The left ventricle becomes congested with blood due to reduced pumping capacity.
- This leads to several consequences, including:
- Increased blood volume due to salt and water retention in the kidneys, thereby increasing blood pressure.
- Pulmonary edema (fluid buildup in the lungs), causing shortness of breath.
- Increased heart rate (HR) and blood vessel constriction (vasoconstriction) due to sympathetic nervous system stimulation.
- Activation of the renin-angiotensin system.
- Reduced cardiac output (CO) and consequently lower oxygen delivery to vital organs like the brain, heart, and kidneys.
CHF Symptoms
- Common symptoms include coughing, tiredness, dizziness, and visual disturbances.
- Pulmonary edema, manifesting as shortness of breath, is a notable symptom.
- Swelling in the abdomen (ascites), legs, and ankles may occur.
- Fluid buildup around the lungs (pleural effusion) is also a potential symptom.
- Weakened myocardial (heart muscle) function may also occur.
CHF Treatment: Drug Therapy Goals
- Dual goals of drug therapy include:
-
Symptom relief: Aiming to alleviate congestion and improve cardiac performance.
- Inotropic drugs: Digoxin, dopamine, dobutamine (increase heart contractility).
- Vasodilators: ACE inhibitors/AT1 antagonists, hydralazine, nitrates (relax blood vessels).
- Beta-blockers: Metoprolol, bisoprolol, carvedilol (regulate heart rate and reduce workload on the heart).
-
Disease progression prevention/reversal: To enhance long-term survival.
- ACE inhibitors/AT1 antagonists: (reduce blood pressure, protect the heart).
- Beta-blockers: (contributing to heart protection and survival).
- Aldosterone antagonists (e.g., spironolactone): (manage fluid retention).
-
Symptom relief: Aiming to alleviate congestion and improve cardiac performance.
CHF Treatment: Non-Pharmacological Measures
- Rest and salt restriction are crucial non-pharmacological components of CHF management.
