The Dragonfly Initiative suddenly took me back to those halcyon days of yore, when I could just sit for hours studying things that I find are of little-to-no clinical relevance. Chronic renal failure? Obsolete. It's Chronic Kidney Disease. Congestive Heart Failure? Obsolete. It's just Heart Failure, or Decompensated Heart Failure, now. There is no such thing as Non-Insulin-Dependent Diabetes Mellitus, either. It's either DM type I or type II. Beta-blockers are standard of care in Decompensated Heart Failure. Digoxin is almost useless, except as a way to achieve rate-control in atrial fibrillation. The difference between Q-wave Myocardial Infarctions and non-Q-wave Myocardial Infarctions are academic and don't make a difference in terms of treatment. What we care about are ST-elevations: STEMIs vs NSTEMIs/unstable angina. And it's all called Acute Coronary Syndrome now.
