1 / Ejection Fraction 🔹 HF w reduced EF (HFrEF): LVEF ≤40% 🔹 HF w preserved EF (HFpEF): LVEF ≥50% 🔹 HF w mildly reduced EF (HFmrEF): LVEF 41–49% 🔹 HF w improved EF (HFimpEF): LVEF ≤40% + ≥10 pt increase from baseline, w/ 2nd >40% But what about systolic vs diastolic?

Epic list of tricky diagnoses in IM by Anil Makam. My take on each of them: 🟡 UTI: historical precedent in medical education has made many clinicians anchor on "UTI" in patients with bacteriuria, which is fairly prevalent in our elders & often asymptomatic. This is worsened by

Using the Neutrophil-to-Lymphocyte Ratio as a “free upgrade to the CBC” (h/t 𝙟𝙤𝙨𝙝 𝙛𝙖𝙧𝙠𝙖𝙨 💊) helped me to diagnose aortic dissection in a young patient recently. If you’re discharging a patient with a NLR >10, it’s worth a second look.
