Study Notes
Cardiovascular Pharmacology
- Cardiovascular pharmacology encompasses various medications targeting heart and blood vessels.
- Medications for heart conditions are categorized into different types, including those for blood vessels, hyperlipidemia, anticoagulants, and antiplatelet agents.
Myocardial Ischemia - Angina
- Angina is not a disease, but a symptom of an underlying condition.
- It's characterized by pressure, squeezing, or pain in the chest.
- Angina occurs when a portion of the heart muscle is deprived of sufficient oxygen.
Anti-Ischemic Drug Therapy
- Anti-ischemic drugs aim to reduce myocardial oxygen consumption.
- Strategies include lowering heart rate, blood pressure, and myocardial contractility.
- Increasing myocardial oxygen supply, specifically through coronary vasodilation, is another crucial aspect.
Nitroglycerin (Anti-Ischemic)
- Nitroglycerin is a vasodilator, widely used for treating angina.
- This drug provides relief to chest pain associated with reduced blood supply to the heart.
Common Calcium Channel Blockers (e.g., Nimodipine)
- Nimodipine is a lipid-soluble calcium channel blocker.
- It crosses the blood-brain barrier, a characteristic making it useful post intracerebral bleeding.
- Vascular spasm, narrowing of the arteries. and reduced blood flow are characteristics addressed by this drug.
Main Types of Calcium Channel Blockers
- Dihydropyridines (e.g., Nimodipine): target blood vessels, causing relaxation.
- Non-dihydropyridines (e.g., Diltiazem, Verapamil): target both blood vessels and heart muscle, effective in treating heart rhythm problems.
Thiazide Diuretics
- Thiazide diuretics are common for fluid reduction.
- They also cause blood vessel relaxation.
- Precautions include avoiding their use in cases of dehydration, anuria, electrolyte abnormalities, and known hypersensitivity.
Angiotensin Receptor Blockers (ARBs)
- ARBs (also known as angiotensin II receptor antagonists) are used in high blood pressure and heart failure therapy.
- They are also used in chronic kidney disease and prescribed post heart attack.
Chronic and Acute Heart Failure
- Chronic heart failure is a progressive condition where the heart struggles to pump blood effectively.
- Acute heart failure is a sudden, life-threatening condition where the heart cannot perform its pumping function adequately.
