About

Cardio Shock

This medical app calculates CPO and PAPi to help assess patient candidacy for mechanical support. It utilizes formulas based on research from The Detroit Shock Initiative to provide these critical medical calculations.

Highlights
  • CPO calculation
  • PAPi calculation
  • Mechanical support assessment
  • Based on Detroit Shock Initiative findings
  • BSA and Fick formulas

Calculate CPO and PAPi to assess if patient is a candidate for mechanical support. The "recommendations" are based on the findings of The Detroit Shock Initiative: Basir MB, Schreiber T, Dixon S, Alaswad K, Patel K, Almany S, Khandelwal A, Hanson I, George A, Ashbrook M, Blank N, Abdelsalam M, Sareen N, Timmis SBH, O'Neill Md WW. Feasibility of early mechanical circulatory support in acute myocardial infarction complicated by cardiogenic shock: The Detroit cardiogenic shock initiative. Catheter Cardiovasc Interv. 2018 Feb 15;91(3):454-461. doi: 10.1002/ccd.27427. Epub 2017 Dec 20. PubMed PMID: 29266676. Disclaimer: Please note that this app does not replace clinical judgement. I can not take responsibility for the outcomes of the use of this app. There is no single standard formula for the calculation of BSA or cardiac output. Many authors recommend reducing peak oxygen consumption to 110mL O2/min for patients over the age of 75. This app uses the standard 125mL O2/min for all patients. Formulas: BSA is calculated as square root (heigh*weight)/36 Fick calculated as 125xBSA/ ((SAO2-SVO2) * hgb * 13.4. Finally: I have no relevant financial conflicts of interests or financial gains from use of this app. I'm just another idealistic general cardiology fellow looking to make a difference.

The IVUSAID App is a free educational mobile application which has been developed to teach medical professionals how to use intravascular ultrasound (IVUS) for PCI guidance based on the current guidelines using our extensive experience and large database of complex coronary cases. Despite the growing body of evidence for clinical benefits of IVUS-guided PCI, IVUS remains underutilized in much of the world including the United States. Challenges in image interpretation and education are among the barriers to widespread adoption of IVUS in everyday clinical practice. Mount Sinai Heart is a global leader within the field of interventional cardiology as well as mobile apps development. The myriad of cases and pathology which are seen in The Mount Sinai Cardiac Catheterization Laboratory make it the perfect center to educate medical professionals within this field. The Key Concepts section of IVUSAID describes principles of IVUS, image acquisition, and concepts of ultrasound behavior in various tissues. The Image Interpretation section of the app has dozens of representative cross-sectional images, videos, and descriptions of plaque types, stent apposition and expansion, artifacts, and more. A short video for each type of lesion or artifact and post-stent findings, in addition to an annotated representative cross section aims to overcome a major limitation of any article or book on IVUS which present a static image, since the actual IVUS pullback is dynamic. Twenty-one complex coronary cases demonstrate IVUS guidance in a variety of patient presentations and lesions including ACS, LM bifurcation, severely calcified lesions and calcified nodules, spontaneous coronary artery dissection, and malapposed stents as well as how IVUS was used to inform treatment decisions. An extensive quiz section helps deliver educational content in a more interactive format where answers are accompanied by detailed explanations and references. We hope that IVUSAID will help techs, fellows, and early-career physicians incorporate IVUS in their daily practice for stent sizing, post-stent optimization, and identification of appropriate treatment strategies.
