[The natural development of arteriosclerotic coronary disease. Coronarographic study in time intervals]
Insights
Smoking is the only identified risk factor predicting the progression of coronary atherosclerosis in patients with coronary artery disease. Coronary arteriography revealed lesion progression linked to angina and myocardial infarction, while resting ECG showed no predictive value.
Area of Science:
- Cardiology
- Atherosclerosis Research
Background:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Understanding the progression of coronary atherosclerosis is crucial for patient management.
- Identifying factors influencing disease progression can aid in risk stratification.
Purpose of the Study:
- To determine the rate of progression of coronary atherosclerosis in patients with established CAD.
- To identify clinical and angiographic factors associated with the progression of coronary atherosclerotic lesions.
- To evaluate the predictive value of resting electrocardiogram (ECG) for disease evolution.
Main Methods:
- Serial coronary arteriography performed at least twice with several months between procedures in 96 CAD patients.
- Angiographic assessment to identify patients with progression versus non-progression of coronary lesions.
- Analysis of clinical data, including smoking status and resting ECG, in relation to angiographic findings.
Main Results:
- A significant proportion of patients showed progression of coronary atherosclerotic lesions.
- Angiographic progression of lesions across major coronary branches correlated with worsening angina and myocardial infarction.
- Current smoking was identified as the sole significant risk factor predicting the progression of coronary atherosclerosis.
Conclusions:
- Coronary atherosclerosis progression is a dynamic process in a subset of CAD patients.
- Angiographic evidence of widespread lesion progression is linked to adverse clinical events.
- Smoking cessation should be strongly advised as it is a key modifiable factor influencing CAD progression.
Abstract:
In 96 patients with coronary artery disease a coronary arteriography was performed twice at least with some months' interval, in order to establish the rate of progression of coronary atherosclerosis and the factors which could affect this progression. It was possible to select patients with progression of the coronary arteria lesions from patients with no increase of coronary stenosis. From the angiographic point of view, the progression of angina and the appearance of myocardial infarction are connected with a general progression of arterial lesions on all main coronary branches. As to the electrocardiographic aspects, the ECG at rest give no informations about the evolution of the coronary disease. Among the risk factors the smoking only has some importance in order to predict the progression of the coronary atherosclerosis.
