First clinical report of echo left ventricular function during intracoronary SSO2 infusion after anterior STEMI stenting
Cardiac Interventions Today
A man in his mid 40s presented to the emergency department (ED) with a chief complaint of severe substernal chest pain with associated nausea and vomiting that began 3 hours prior. On arrival at the ED, the patient’s blood pressure was 138/91 mm Hg, his heart rate was 70 bpm, and his respiratory rate was 18 to 20 breaths/min with oxygen saturation > 95% on room air. A physical examination showed a regular heart rate and rhythm with no murmur, rubs, or gallops. The baseline troponin was 0.10 ng/mL. The electrocardiogram (ECG) showed prominent anteroseptal/lateral ST-segment elevations with reciprocal inferior changes. A bedside transthoracic echocardiogram (TTE) showed a left ventricular ejection fraction (LVEF) of 30% to 35%. He was given a 324-mg oral tablet of aspirin, a 180-mg oral tablet of ticagrelor, and placed on intravenous (IV) nitroglycerin and IV heparin prior to transfer to the cardiac catheterization lab. The patient’s history included prior diagnoses of hypertension and hyperlipidemia.
