  • Introduction

  • The Heart Attack Survival Calculator provides an instant assessment of the probability of surviving an acute myocardial infarction (commonly called heart attack). The probability calculation is derived from a statistical disease model, developed by MediQual, which is based on twenty-one different independent variables. Initially, the Heart Attack Survival Calculator is calibrated for normal values, assuming a patient is sixty years old. If the patient's age is changed, the normal values will automatically adjust.
  • How to navigate

  • The Survival Calculator is designed like many web applications. Two buttons - CALCULATE and RESET - generate results and clear them. Underlined blue text is linked to supporting information pages for your convenience. All information pages have a navigation bar at the top for easy reference. To enter data, click on the appropriate box to enter numbers or press the space bar to mark a check box. On most browsers, the Tab key will move your cursor from box to box.
  • How to calculate

  • To begin a calculation, click the RESET button to move the cursor to the Age box under Patient History. Begin by entering the patient's age in years (the default is set at 60). Hit the Tab key to move to the next box. Continue to enter values or mark check boxes until all patient data has been entered. Click on the blue section headers if you need definitions or other assistance. If you lack complete data, like a missing lab result, simply use the displayed normal value. Click the CALCULATE button and the probability of survival will be instantly displayed.

    To modify your calculation, enter a new value in a box and click CALCULATE for a new result. Click RESET to restore normal values for a new calculation.
