Study Notes

Cardiovascular Disease

Cardiovascular Disease is a broad topic encompassing various conditions affecting the heart and blood vessels.
Risk factors for cardiovascular disease include, but are not limited to: congestive heart failure, hypertension, age over 75, diabetes, stroke or TIA, vascular disease and those aged 65-74.
Atrial fibrillation (AF) and atrial flutter (AFL) are common arrhythmias.
Anticoagulation therapy is crucial for managing atrial fibrillation.
Other common arrhythmias include premature atrial contractions (PACs) and premature ventricular contractions (PVCs).
Inflammatory and infectious heart conditions such as, acute pericarditis, myocarditis, and infective endocarditis are also discussed.
Various diagnostic tools including ECG, echocardiograms, and cardiac markers are used in evaluating these conditions.

Learning Objectives

The document outlines key learning objectives, including recommending ablation for AF, prescribing anticoagulants, anticoagulation in older adults and considering premature atrial contractions/premature ventricular contractions as predictors of atrial fibrillation.
It also covers guideline recommendations, antibiotic prophylaxis and acute pericarditis.

Key Practice Recommendations

Recommendations on managing AF include synchronized direct current cardioversion, catheter ablation, and/or pharmacotherapy.
Anticoagulation is recommended based on risk factors, using CHA2DS2-VASc score and HAS-BLED score
Colchicine plus nonsteroidal anti-inflammatory drugs are first-line treatment for acute pericarditis
Antibiotics are crucial in cases of infective endocarditis.
