Protocol - Myocardial Infarction

Description:

This measure assesses if an individual has had a myocardial infarction (MI) through collection of personal history of disease, treatment and procedure histories, and medical record abstraction.

Protocol:

1. Has a doctor ever told you that you had a myocardial infarction or heart attack?

[] 1 Yes

[] 0 No

[] 9 Don't Know

2. Have you had an outpatient or day surgery procedure to unblock blocked or narrowed blood vessels of the heart (called a PTCA, coronary angioplasty, stent, or atherectomy)?

[] 1 Yes

[] 0 No

Remainder of protocol to be abstracted from patient's hospital medical records.

3. Was there an acute episode of pain, discomfort or tightness in the chest, left arm or jaw within 72 hours of the hospitalization or within 72 hours of the in-hospital event?

[] Yes

[] No

[] Unknown

4. Was the discomfort or pain diagnosed as having a non-cardiac origin?

[] Yes

[] No

[] Unknown

5. Were electrocardiograms (ECGs or EKGs) recorded?

[] Yes

[] No

[] Unknown

If "No" or "Unknown," skip to 6.

Record dates of ECGs and make two copies of FOUR ECG tracings as described below. Send one copy to the ECG Reading Center and attach one copy to this form:

-- If four or fewer tracings were made, include all tracings.

-- If more than four tracings were made, include:

1. First two codable tracings after admission (ECG#1-First and ECG#2)

2. Last codable tracing prior to discharge or death (discharge tracing) (ECG-Last)

3. Last codable tracing on day 3 (or the first tracing thereafter) following an admission or in-hospital event (ECG#3)

4. The next codable tracing after day 3

-- If the participant is readmitted (transferred) to the ICU/CCU because of a new episode of chest pain, the first codable tracing may be sent.

Serum Enzymes

6. Were any cardiac enzyme measurements performed during this admission?

[] Yes

[] No

If "No," skip to end.

7. Did the participant have any active liver disease (cirrhosis, hepatitis, liver cancer, etc.)?

[] Yes

[] No

If "Yes," specify:

_____________________________________________________

8. Is there any evidence of hemolytic disease during this hospitalization?

[] Yes

[] No

9. Is there any mention of the participant having either trauma, a _ procedure, or rhabdomyolysis within one week prior to the measurement of the cardiac enzymes?

[] Yes

[] No

[] Unknown

If "Yes," please specify type of trauma or procedure below.

Date m/d/y: __ / __ / __ __

Type of Trauma or procedure:

__________________________________________

* Please complete ENZYME CHART. *

10. Myocardial infarction

[] Definite

[] Probable

[] No MI (skip to end)

If “Definite” or “Probable” enter date of MI (MM/DD/YYYY): __ __ / __ __ / __ __ __ __

Criteria

11. Chest Pain

[] Present

[] Absent

12. Cardiac Enzymes

[] Abnormal

[] Equivocal

[] Incomplete

[] Normal

13. ECG Serial Reading (pick one)

[] Evolution of Major Q-Wave

[] Evolution of ST-T Elevation with or without Q-Wave

[] New LBBB

[] Evolution of ST-Depression/Inversion alone

[] Evolution of Minor Q-Wave alone

[] Single ECG with Major Q-Wave

[] Single ECG with LBBB, described as new

[] Absent, Uncodable or Other ECG

14. Procedure-related:

[] Yes, cardiovascular

[] Yes, non-cardiovascular

[] No

Diagnostic Criteria:

Acute, Evolving or Recent MI

Either one of the following criteria satisfies the diagnosis for an acute, evolving or recent MI:

1. Typical rise and gradual fall (troponin) or more rapid rise and fall (CK-MB) of biochemical markers of myocardial necrosis with at least one of the following:

ischemic symptoms;
development of pathologic Q waves on the ECG;
ECG changes indicative of ischemia (ST segment elevation or depression); or
coronary artery intervention (e.g., coronary angioplasty).

2. Pathologic findings of an acute MI.

Established MI

Any one of the following criteria satisfies the diagnosis for established MI:

1. Development of new pathologic Q waves on serial ECGs. The patient may or may not remember previous symptoms. Biochemical markers of myocardial necrosis may have normalized, depending on the length of time that has passed since the infarct developed.

2. Pathologic findings of a healed or healing MI.

Personnel and Training Required

An interviewer who is trained to conduct personal interviews with individuals from the general population is required to complete the protocols from the Cardiovascular Health Study (CHS) and the Women's Health Initiative (WHI). The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "don't know" response is provided.

*There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).

A trained and certified Hospital Record Abstractor is required to complete the protocol from the Multi-Ethnic Study of Atherosclerosis (MESA). This person should be trained to perform medical record and chart abstraction using various hospital records.

Equipment Needs

None

Requirements

Requirement Category	Required
Major equipment	No
Specialized training	Yes
Specialized requirements for biospecimen collection	No
Average time of greater than 15 minutes in an unaffected individual	No

Mode of Administration

Interviewer-administered question, Medical record abstraction

Life Stage:

Adult

Participants:

Cardiovascular Health Study (CHS): >65 years old

Women's Health Initiative (WHI): women ages 50–79 years old*

Multi-Ethnic Study of Atherosclerosis (MESA): ages 45–85 years old

*While this questionnaire was used in a women's study, the Cardiovascular Working Group deems it appropriate to use with men.

Specific Instructions:

If the respondent answers "yes" to question 1 or question 2, the interviewer should complete the rest of the protocol. If the respondent answers "no" or "don't know," then the protocol is deemed complete.

Selection Rationale

A combination of four protocols was chosen to obtain sufficient data to assess whether a person had a myocardial infarction. Obtaining a personal history of myocardial infarction and treatment procedures, in combination with medical record abstraction, will provide a high level of specificity and reliability.
