[Possibilities and limits of the diagnosis of coronary disease in general practice]
Insights
This study discusses angina pectoris diagnosis and management. It emphasizes early investigation, especially coronary angiography, for recurrent angina post-surgery or post-infarction, and in men with typical primary angina.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Angina pectoris, a symptom of coronary artery disease, presents in various forms.
- Prinzmetal angina is less common and often overlooked by general practitioners.
- Specific clinical scenarios necessitate prompt and thorough diagnostic evaluation.
Purpose of the Study:
- To outline diagnostic strategies for different types of angina pectoris.
- To emphasize the role of coronary angiography in specific patient groups.
- To guide the management of angina pectoris when medical therapy fails.
Main Methods:
- Review of diagnostic approaches for angina pectoris.
- Discussion of indications for coronary angiography.
- Consideration of patient demographics (sex) in diagnostic decision-making.
Main Results:
- Recurrent angina after bypass surgery and post-infarction angina warrant immediate coronary angiography.
- In men with typical primary angina, angiography is crucial to assess surgical candidacy if medical therapy fails.
- Women with typical primary angina require similar evaluation, acknowledging a higher likelihood of normal coronary arteries.
Conclusions:
- Early and active investigation, including coronary angiography, is vital for managing specific angina presentations.
- Atypical angina forms, particularly with normal resting and exercise ECGs, still require consideration for further investigation.
- Diagnostic strategies should be tailored, considering the probability of underlying coronary artery disease and patient characteristics.
Abstract:
Among the various forms of angina pectoris related to coronary artery disease, the Prinzmetal type is only seldom within the diagnostic possibilities of the general practitioner. Angina pectoris recurring after coronary artery bypass surgery calls for prompt coronary angiography. An active approach is also justified in postinfarction angina because of the usually severe underlying coronary lesions. Therefore, failure of medical therapy calls for further early investigations. In typical primary angina pectoris in man, failure of medical therapy requires angiography mainly to determine whether surgery is feasible. The same attitude should be followed in women, but bearing in mind that the probability of intact coronary arteries is much greater. The goal of the examination is then to "calm" the situation. In atypical forms of primary angina pectoris there is a high probability of intact coronary arteries, especially if the ECG at rest and at exercise remains normal. Nevertheless, this probability is not sufficiently great to exclude further investigations (isotopic or angiographic, according to the adopted policy).

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
