I don't know where I was going when I drew Julius Caesar (yes, the resemblance is a little questionable I suppose), but I still felt the need to share him with the world. As I'm currently cramming all the information I can about cardiology, I've decided to fill this post with a cardiology fact of the day!
The difference between eccentric and concentric hypertrophy:
Eccentric hypertrophy: increased preload, hypertrophic sarcomeres added in series.
Associated causes: mitral/aortic regurgitation, left to right shunt
Associated cardiomyopathy: dilated cardiomyopathy
Concentric hypertrophy: increased afterload, hypertrophic sarcomeres added in parallel.
Associated causes: Hypertension, aortic stenosis
Associated cardiomyopathies: hypertrophic and restrictive cardiomyopathies

The difference between systolic and diastolic dysfunction:
Systolic dysfunction: volume overload, decreased ventricular contraction and decreased ejection fraction.
Associated causes: ischemia, myocardial infarction, dilated cardiomyopathy
Diastolic dysfunction: resistance to filling and normal ejection fraction.
Associated causes: hypertension, aortic stenosis, hypertrophic cardiomyopathy, restrictive cardiomyopathies
