SCAD and Shock: Understanding Spontaneous Coronary Artery Dissection Summary: This infographic delves into Spontaneous Coronary Artery Dissection (SCAD), a critical cause of acute coronary events, predominantly affecting women and often linked to pregnancy or postpartum periods. It explores the proposed mechanisms, angiographic appearances, acute management strategies, and long-term care, emphasizing…
Peripartum Cardiomyopathy and Cardiac Arrest Summary: This infographic provides a comprehensive overview of the unique considerations in managing cardiac arrest in pregnant patients. It covers differential diagnosis, important physiologic changes, adaptations to ACLS protocols, post-arrest care, and the role of extra-corporeal life support (ECLS) during pregnancy and postpartum. Key points…
Peripartum Cardiomyopathy and Cardiogenic Shock Definition of Peripartum Cardiomyopathy (PPCM):Diagnosis includes heart failure near the end of pregnancy or within five months postpartum, with LV ejection fraction <45% and idiopathic LV dysfunction excluding other causes. Role of PAC in Cardiogenic Shock:Parameters like cardiac power output (CPO) and pulmonary artery pulsatility…
COVID and Cardiogenic Shock Diagnose Cardiogenic Shock at BedsideOn exam, look for signs of poor flow: narrow pulse pressure, labored respirations or Cheyne-Stokes respirations, abdominal bloating/nausea, evidence of volume overload, and cool extremities. If PAC is available, a mixed venous O₂ less than 55-60% is suggestive of cardiogenic shock. COVID…
5 Steps of Pulmonary Embolism (PE) Management Suspect PE Consider Risk Factors: Recent surgery, prolonged immobilization, active cancer, etc. Symptoms: Sudden onset of dyspnea, chest pain, and tachycardia. PERC Criteria: Utilized to rule out PE in low-risk patients. Estimate Risk of PE Clinical Tools: Use Well's score and Geneva score…
B.R.A.S.H Syndrome Bradycardia, Renal Failure, AV Nodal Blockade, Shock, and Hyperkalemia This infographic provides a comprehensive look at B.R.A.S.H syndrome, a critical condition resulting from the interaction of AV nodal blockade, hyperkalemia, and renal failure, leading to bradycardia and shock. Differential Diagnosis B.R.A.S.H results from the combined effects of AV…
Inotropes This infographic provides a detailed breakdown of inotropes, including their mechanisms, clinical applications, and adverse effects. What are Inotropes? Inotropes increase the force of myocardial contraction. Their effects vary depending on which adrenergic receptors they activate: Alpha-1: Vasoconstriction Beta-1: Increases inotropy (contractility) and chronotropy (heart rate) Beta-2: Vasodilation Why…
VA ECMO Increases Afterload This infographic illustrates the hemodynamic effects of VA ECMO (veno-arterial extracorporeal membrane oxygenation) on left ventricular performance, focusing on the pressure-volume (P-V) loop and the implications of increased afterload. P-V Loop at Different ECMO FlowsThe diagram shows how higher ECMO flow rates increase afterload, limiting left…
