A: CORONARY ARTERY DISEASE Flashcards
A general term that refers to several diseases other than atherosclerosis
Coronary Artery Disease
heart disease with primary manifestations that result from myocardial ischemia owing to atherosclerotic CAD
Ischemic Heart Disease
An episodic, reversible oxygen insufficiency, is the most common form of IHD
Angina Pectoris
Chest discomfort that are attributable to insufficient myocardial oxygen
Angina Pectoris
Types of Angina
*Stable (Classic) Angina
*Unstable Angina
*Angina Decubitus
*Prinzmetal Angina
More predictable pattern
Stable (Classic) Angina
Stable (Classic) Angina is relieved by
Rest or Nitroglycerin
Pain has referred as SQUEEZING, GRIP LIKE SUFFOCATING
Stable (Classic) Angina
Lasts for minutes
Stable (Classic) Angina
Angina at rest
Unstable Angina
Decreased responded to NTG
Unstable Angina
Angina Decubitus is also known as
Nocturnal angina
Not specifically related to either rest or exertion
Angina Decubitus
Gravitational forces shifts fluid within body
Angina Decubitus
Angina Decubitus drugs reduce left ventricular volume
Diuretics alone or in combination
Angina Decubitus: Nitroglycerin may relieve
Paroxysmal nocturnal dyspnea (PND)
Occurs at rest
Prinzmetal Angina
What drugs are used for the treatment of Prinzmetal Angina
Calcium Channel Blocker and Beta blockers
In this type of Angina, the Nitroglycerin doesn’t provide relief
Prinzmetal Angina
Bind bile acids within the intestines and prevent from being reabsorbed
Bile Acid Binding Resins
Drugs of Bile Acid Binding Resins
- Cholestyramine
- Colestipol
- Colesevelam
Inhibit the enzyme HMG-CoA, resulting in reduction of cholesterol
Statins or HMG COA Inhibitor
Drugs of Statins or HMG COA Inhibitor
*Atorvastatin
*Fluvastatin
*Lovastatin
*Pitavastatin
*Pravastatin
*Rosuvastatin
*Simvastatin
Inhibits cholesterol synthesis and lower LDL and bile acids
Fibric Acid Derivatives
Precautions in Fibric Acid Derivatives
- GI effects
- Affects Liver function test
Drugs of Fibric Acid Derivatives
Fenofibrate and Gemfibrozil
Lowering of LDL and triglycerides
Niacinamide
Respiration of oxidation - reduction reactions
Niacinamide
Indication of Niacinamide
Elevated total cholesterol and low LDL
Special Precautions in Niacinamide
- GI effects
- Itchy skin
- Cases of severe liver toxicity
Inhibits the intestinal absorption of cholesterol and related phytosterols
Ezetimibe
Indication of Ezetimibe
- Adjunctive therapy along with dietary measures
- Used in combination with STATINS
Venous dilation
Nitrates
Indication of Nitrates
Acute attacks of angina pectoris
Associated with long term use of nitrates
Nitrate Tolerance
Reduction of oxygen demand
Beta Blocker
Safety Precautions in Beta Blocker
- Should be avoided in Prinzmetal angina
- Asthma is a relative contraindication
- Hypoglycemia
All beta blockers are likely to be equally effective for
Stable angina
Reverse coronary spasm by inhibiting calcium influx
Calcium Channel Blockers
Decrease coronary vascular resistance
Calcium Channel Blockers
Used in stable angina that is not controlled by nitrates and beta blockers and in patients for whom beta blocker therapy is not advisable
Calcium Channel Blockers
Drugs of Calcium Channel Blocker
Verapamil
Diltiazem
Nifedipine
Inhibits platelet aggregation induced by adenosine diphosphate
Ticlopidine
Just like ticlopidine but produces anti thrombotic effect
Clopidogrel
Drugs of Antiplatelet Agents
Aspirin
Ticlopidine
Clopidogrel
Recommended for clinically diagnosed hypertensive agents who are experiencing angina
ACE & ARBs
