Patient handout

Acute HF — diabetic cardiomyopathy

PRODUCTION

1. Your condition

This handout is for acute hf — diabetic cardiomyopathy. Your care team identified this based on: dyspnea / orthopnea / edema in t2dm ≥10 yr without obstructive cad or long-standing htn → diabetic cardiomyopathy pathway.

Other reasons your team may use this plan: nt-probnp elevated + hba1c >9% + concurrent diabetic microvascular complications (retinopathy/nephropathy/neuropathy); echo grade ii/iii diastolic dysfunction + lvh + impaired gls (global longitudinal strain) in diabetic patient — early diabetic cardiomyopathy; cardiac mri diffuse subendocardial lge pattern + increased t1/ecv in diabetic patient with hf.

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

semaglutide0.25 mg SC weekly × 4 wk → titrate to 2.4 mg weekly (HFpEF + obesity) or 1 mg weekly (T2DM)SCweeklySTEP-HFpEF (Kosiborod NEJM 2023 PMID 37877559) — semaglutide 2.4 mg weekly in obese HFpEF: 5%+ weight loss, KCCQ + 6MWD improvement; SELECT cardiovascular benefit independent of T2DM
metformin500 mg PO BID, titrate to 1000 mg BIDPOBIDADA 2024 first-line oral; HOLD during acute illness (lactic acidosis risk); restart when stable + eGFR ≥30

furosemide40 mg IV (or 2.5x outpatient dose for chronic users — DOSE-AHF PMID 21366472)IV/POq12h titrate to UOP 100–200 mL/hStandard ADHF decongestion; DOSE-AHF — high-dose strategy improves dyspnea more than low; transition to PO when stable
sacubitril-valsartan24/26 mg PO BID titrate to 97/103 mg BIDPOBIDPIONEER-HF (Velazquez NEJM 2019 PMID 30403955) — in-hospital initiation safe + reduces NT-proBNP more than enalapril; ACC/AHA 2022 HF Class I in HFrEF

Plan: Diabetic cardiomyopathy ADHF — SGLT2i-first regimen (EMPULSE PMID 35347356 + ACC/AHA 2022 HF + ADA 2024)

3. When to call your provider

Contact your care team if any of the following happen:

  • Progressive HF on max the four foundational heart-failure medications → advanced HF / transplant eval
  • Worsening renal function → reassess SGLT2i + ARNI
  • New microvascular event → intensify glucose + BP control

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

  • DKA (T1DM) or HHS (T2DM) superimposed on ADHF — combined cardiogenic + osmotic emergency(life-threatening)
  • Pioglitazone or rosiglitazone prescribed in patient with HF (transferred from other facility or continued from outpatient regimen)
  • Saxagliptin prescribed in patient with HF — SAVOR-TIMI 53 (Scirica NEJM 2013 PMID 23992602) HF hospitalization signal

5. Follow-up

Cardiology + endocrinology co-clinic; STRONG-HF–style up-titration weekly × 4; HbA1c at 3 mo; ophthalmology + nephrology follow-up; semaglutide initiation if HFpEF + obesity; CGM consideration
