Insights
Single-vessel coronary artery disease is not always benign, often leading to myocardial infarction. Invasive therapy may offer better improvement than medical treatment for these patients.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Single-vessel coronary artery disease (SVCD) was historically viewed as a benign condition.
- Medical therapy was often considered the optimal treatment for SVCD.
Purpose of the Study:
- To assess the effectiveness of medical therapy versus surgical intervention for single-vessel coronary artery disease.
- To evaluate the association of SVCD with adverse cardiac events such as myocardial infarction and aneurysm.
Main Methods:
- A retrospective study of 323 patients with ischemic heart disease and confirmed single-vessel coronary artery disease.
- Coronary angiography was used to identify the affected vessel and assess disease severity.
- Patients were divided into two groups: 42 undergoing coronary artery bypass surgery and the remainder receiving medical therapy.
Main Results:
- Single-vessel coronary artery disease was frequently associated with myocardial infarction and post-infarction aneurysm.
- The left anterior descending artery was the most commonly affected vessel, with involvement linked to poorer outcomes.
- Surgical intervention led to better clinical improvement compared to medical management, although survival rates were not statistically different.
- Circumflex artery lesions presented a surprisingly high risk.
Conclusions:
- Single-vessel coronary artery disease can be associated with significant adverse events, challenging its benign perception.
- Invasive therapies, including percutaneous transluminal coronary angioplasty, may be increasingly justified for recent onset angina due to promising results.
- The findings suggest a potential shift towards considering more aggressive treatment strategies for specific SVCD presentations.
Abstract:
Single-vessel coronary disease has been considered so far a benign condition, for which the medical therapy may represent the optimal treatment. In order to assess the effectiveness of this approach, we studied 323 patients who had come to our attention for ischemic heart disease and resulted affected by single-vessel coronary artery disease. From our data it appears that single-vessel coronary artery disease is frequently associated with myocardial infarction and post-infarction aneurysm. Coronary angiography indicated that left anterior descending coronary artery is the most frequently affected vessel, and that its involvement is often associated with lethal outcome. Forty-two out of the 323 patients underwent coronary artery bypass surgery; the remaining patients were medically treated. Surgical patients showed a better improvement respect to the medical group, while survival was not statistically different. An unexpected result was the relatively high risk in circumflex artery lesion. These data may justify a broader utilization of invasive therapy in recent onset angina, in light of the excellent results recently obtained with percutaneous transluminal coronary angioplasty.
