Acute coronary syndrome risk calculation in patients with chest pain at the Emergency Department

This web page aims to help clinicians to assess clinical risk for acute coronary syndrome in patients presenting with chest pain at the Emergency Department. Please follow the instructions below.

Instructions 

Based on our research study, the formula below provides a simple way to calculate the chance of having acute coronary syndrome in individuals who have chest pain. Just fill out 5 values below.


Gender: female = 0, male = 1

Age: years

CAD: previous history of coronary artery disease

DM: no diabetes = 0, diabetes = 1

Chest pain: having one character of angina pain including  chest tightness; squeeze pain at retrosternum; referred to shoulder, arm, or mandible; dyspnea or tachypnea; associated with sweating or palpitation without other obvious causes; syncope or fainting; improved with sublingual nitroglycerin.



From these five values, you will get the probability of having acute coronary syndrome in patients with chest pain. The highest probability is 1 or 100%.
