N/A To evaluate the clinical differences between Q wave myocardial infarction and non-Q wave myocardial infarction, the records of 336 patients with first myocardial infarction were reviewed. According to the presence or absence of Q waves on electrocardiogram, the patients were divided into two groups: a Q wave myocardial infarction group and a non-Q wave myocardial infarction group. The results were as follows: 1) According to standard electrocardiographic criteria, among 336 patients 271 patients (80.6%) had Q wave myocardial infarctions, and 65 patients (19.4%) had non-Q wave myocaridal infarctions. 2) The average age and male-to-female ratio were similar in the two groups. There were no significant differencres between the two groups in serum cholesterol levels and in incidences of a history of hypertension and diabetes mellitus. 3) Peak cardiac enzyme levels of CPK and LDH were significantly higher in the Q wave myocardial infarction group than in the non-Q-wave myocardial infarctions group. 4) When the complications of arrythmia, congestive heart failure and hospital mortality were compaired, incidences of AV block and congestive heart failure were significantly higher in the Q wave myocardial infarction group, but there was no difference in hospital mortality between the two groups. 5) Incidences of recurrent angina, congestive heart failure, reinfarction, death, and cause of death were not different statistically between the two groups, even though there was a tendency to have more recurrent angina and reinfarction in the non-Q wave myocardial infarction group and more congestive heart failure in the Q wave myocardial infarction group.
