Cholesterol and fat in blood creates plaque in arteries Plaque buildup called atherosclerosis Narrowing of the arteries causes less blood flow to heart and oxygen is deprived to heart, called ischemia Plaque can rupture, causing a clot, which can lead to a heart attack (myocardial infarction or MI) Leads to chest pain with or without activity, fatigue, shortness of breath Atherosclerotic Plaque What is Cardiovascular Disease?

Ensure patient is on appropriate statin therapy and is adherent to medications If aspirin is recommended, make sure patient understands which one, how to take it Assess for side effects to statins (muscle pain, fatigue) Statins can have side effects which deter patients from taking them Identify cost-related issues (i.e., rosuvastatin can be costly) Encourage positive lifestyle choices 6

Irregular rhythm or quivering of the atria of the heart Affects 2.7 million people in the United States Different causes include high blood pressure, coronary artery disease, and other unknown causes Symptoms of AF include fatigue, dizziness, rapid heartbeat Can lead to strokes, heart failure, additional arrhythmias Causes 15-20% of strokes What is Atrial Fibrillation (AFib or AF)?

Patients often take a blood thinner to reduce stroke risk Stroke risk is calculated to assess if medication is needed Most common anticoagulant used is warfarin (Coumadin) Newer oral anticoagulants are available for AF Rivaroxaban (Xarelto) Factor Xa Inhibitor Apixaban (Eliquis) Direct Factor Xa Inhibitor Dabigitran (Pradaxa) Direct Thrombin Inhibitor Pharmacotherapy Vitamin K antagonist (works on many clotting factors) Most common and used for multiple clotting disorders Warfarin requires special monitoring to ensure safety International Normalized Ratio (INR) is primary blood test Goal INR for AF is typically 2-3, checked every 1-6 weeks Bleeding can be reversed by Vitamin K or blood products Coumadin Tablets Generic Tablets What is Atrial Fibrillation (AFib or AF)?

INR affected by antibiotics, heart medications, and many other common medications (including OTCs!) Dark, leafy green vegetables, green tea, liver, and other Vitamin K containing foods all lower the INR Exercise, alcohol intake, tobacco use, and general health can affect INR One missed day or extra dose of warfarin can affect INR Therefore, it is very important to teach patients their lifestyle, medication, diet, and health changes can affect their INR, and will therefore need closer monitoring!
