CHA₂DS₂-VASc Case-Based Questions
Case 1
A 76-year-old male presents to your clinic with a history of persistent atrial fibrillation diagnosed two months ago. His medical history includes hypertension for 10 years and heart failure with reduced ejection fraction (EF 35%). He is compliant with his medications, which include a beta-blocker, ACE inhibitor, and diuretic. He has no history of stroke, diabetes, or vascular disease.
What is his CHA₂DS₂-VASc score, and what is the appropriate recommendation regarding anticoagulation therapy?
Case 2
A 68-year-old female presents with newly diagnosed atrial fibrillation. She has a past history of type 2 diabetes mellitus and underwent coronary artery bypass grafting (CABG) 5 years ago for ischemic heart disease. She denies any history of stroke or transient ischemic attack. Her blood pressure today is 132/84 mmHg, and she is currently not on any antihypertensives.
Based on her clinical profile, calculate her CHA₂DS₂-VASc score and determine the need for anticoagulation.
Case 3
A 58-year-old man presents for routine follow-up and is incidentally found to be in atrial fibrillation on ECG. He reports no symptoms and has no prior history of cardiovascular disease, diabetes, or hypertension. His physical exam and lab results are unremarkable. He is a non-smoker, non-drinker, and exercises regularly.
Should anticoagulation be initiated for stroke prevention in this patient? Justify your answer using the CHA₂DS₂-VASc score.
Case 4
A 72-year-old woman with a history of hypertension and prior ischemic stroke presents to your clinic for management of her atrial fibrillation. She also has moderate chronic kidney disease and osteoarthritis but no known diabetes or vascular disease.
Determine her CHA₂DS₂-VASc score and outline the management strategy for stroke prevention in atrial fibrillation.
Case 5
A 65-year-old male patient is referred for evaluation of newly diagnosed atrial fibrillation. He has a history of peripheral artery disease and poorly controlled type 2 diabetes. He denies any history of stroke, heart failure, or hypertension. He is currently on aspirin and a statin.
What is his CHA₂DS₂-VASc score? Would you recommend anticoagulation therapy?
