[Non-transmural myocardial infarctions. Evolutive ecgraphic and angiographic clinical aspects (author's transl)]
Insights
Fifty-nine cases of non-transmural myocardial infarction were analyzed. Many patients experienced chest pain, with some progressing to transmural infarction, but long-term outcomes varied significantly.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Non-transmural myocardial infarction represents a distinct clinical entity.
- Understanding its characteristics and prognosis is crucial for patient management.
Purpose of the Study:
- To report on fifty-nine cases of non-transmural myocardial infarction.
- To analyze the clinical course, outcomes, and electrocardiographic findings.
Main Methods:
- Diagnosis based on clinical, electrocardiographic (ECG), and enzyme data.
- Follow-up of fifty-five patients for nineteen months.
- Coronary angiography performed in fifteen patients.
Main Results:
- Four patients developed transmural myocardial infarction post-admission.
- Six deaths occurred during follow-up; thirty-one were asymptomatic.
- Fourteen patients experienced angina, often preceding the initial event.
- ECG remained normal in thirty-seven patients.
Conclusions:
- Non-transmural myocardial infarction has a variable clinical course and prognosis.
- Pre-existing angina may be a significant factor in affected patients.
- Further investigation, including coronarography, aids in understanding disease patterns.
Abstract:
The authors report fifty-nine cases of non-transmural myocardial infarction. The diagnosis was made on the basis of clinical electrocardiographic data and enzyme changes. The clinical course was characterized by several chest pain attacks; a transmural myocardial infarction occurred in four patients a few days after admission. Out of fifty-five patients, followed for a nineteen - months period, six died, thirty-one were asymptomatic and fourteen complained of angina. In the last group, chest pain was generally present before the non-transumural myocardial infarction. The ECG were within normal limits in thirty-seven patients. The coronarographic patterns found in fifteen patients are also described and discussed.
