The Quality of Life after Myocardial Infarction (QLMI) instrument can be used to measure quality of life in a patient who has had an acute myocardial infarction (AMI). The instrument identifies those problems that are most frequent or important to patients. The authors are from McMaster University in Hamilton, Ontario, Canada.
The instrument consists of 26 items occurring during the last 2 weeks. Responses are shown based on different colored cards.
Blue card: 1, 2, 4, 6, 8, 10, 11, 12, 13, 14, 15, 16, 17, 19, 20, 22, 23, 24, 25
Yellow card: 3, 5, 26
Pink card: 18, 21
Gray card: 7
Green card: 9

where:
• The values for the gray card did not have a slot for "somewhat satisfied", with the next 3 items moved up 1 slot, and the final entry "none of the time". This doesn't make sense to me, so I took the liberty of modifying the card.
symptoms subscore =
= SUM(points for items 6, 9, 14, 17 and 20)
restriction subscore =
= SUM(points for items 12, 15, 18 and 21)
confidence subscore =
= SUM(points for items 3, 19, 22, 24 and 26)
self-esteem subscore =
= SUM(points for items 2, 11, 13, 16, 23, 25)
emotion subscore =
= SUM(points for items 1, 4, 5, 7, 8 and 10)
total score =
= SUM(points for all 26 items)
Interpretation:
• minimum symptom subscore: 5
• maximum symptom subscore: 35
• minimum restriction subscore: 4
• maximum restriction subscore: 28
• minimum confidence subscore: 5
• maximum confidence subscore: 35
• minimum self-esteem subscore: 6
• maximum self-esteem subscore: 42
• minimum emotion subscore: 6
• maximum emotion subscore: 42
Performance:
• The instrument was found to be reliable and responsive.
• It correlates with other measures in quality of life, anxiety and depression.
