Episode 4: Acute Congestive Heart Failure
May 1, 2010
Dr. Eric Letovsky, an expert in ECG and acute heart failure from Valley Credit Hospital, teams up with Dr. Brian Steinhart, a researcher in cardiac biomarkers at St. Michael's Hospital, to explore the complexities of diagnosing and managing acute congestive heart failure in emergency settings. They discuss practical diagnostic strategies, including the use of BNP and Troponin, as well as the role of ultrasound. The duo emphasizes the challenges in treatment, especially concerning drug considerations and immediate management tactics like BiPAP.

Episode notes
Limit ED Echo To Specific Indications
- Reserve urgent formal echocardiography for new murmur, young unexplained heart failure, or suspected valvular rupture; use ED ultrasound mainly for tamponade.
- Brian Steinhart warns incidental chronic dysfunction on echo can mislead diagnosis.
Treat Hypertensive Pulmonary Edema With Nitrates And BiPAP First
- In hypertensive acute pulmonary edema, prioritize oxygen, early BiPAP, and nitrates before diuretics.
- Eric Letovsky starts 100% O2, calls RT for BiPAP, gives sublingual then IV nitroglycerin and delays furosemide until sympathetic tone reduces.
Avoid Routine High Dose Morphine In Acute Heart Failure
- Avoid routine high‑dose morphine; if used, give small single doses and recognize registry data may be confounded.
- Brian Steinhart prefers 3–4 mg limited dosing and cites ADHERE used much larger cumulative doses.
